Black-footed ferret (Mustela nigripes), a North American species presumed extinct in 1979 until it was rediscovered in 1981. Same thing happened to the Bermuda petrel, peccary, venomous Cuban Solenodon etc.
And the list is much bigger.
The main argument is that if there is no concrete reason, why the organisations are putting the term 'extinct' for a species?
Is it not controversial and funny?
Is it not time to rethink about this problem?
Please jot down your opinions here with any updates in this area.
Thanks in advance.

Answer
It's a very interesting question because in many cases it doesn't seem justified to declare any species extinct if it's not found after conducting a few field surveys. It is clearly mentioned in the 'IUCN Red List categories and criteria, version 3.1, second edition' that "A taxon is Extinct when there is no reasonable doubt that the last individual has died. A taxon is presumed Extinct when exhaustive surveys in known and/or expected habitat, at appropriate times (diurnal, seasonal, annual), throughout its historic range have failed to record an individual. Surveys should be over a time frame appropriate to the taxon’s life cycle and life form."1 The significance of the criteria I see is that it motivates researchers to get involved in more thorough field surveys in order to get any clue about presumed extinct species. In many cases presumed extinct species were rediscovered after a gap of a few years, but it doesn't mean that the previous researcher failed to locate the plant due to less dedication, we know that the distribution of many species is extremely random and the geographical area is so vast, and in some cases inaccessible.
In my opinion, it's not controversial but yes the criteria should be more precise and after the field surveys which failed to record an individual, there should be a set time period after which species should be declared extinct. We also have to understand that we can't be everywhere and thus we miss the plant's population and it happens a lot. If we set a certain time period there are many chances that the researcher could find the species before getting extinct status.

The majority of medicinal plants are obtained from wild resources, making them a worldwide valued resource. Destructive harvesting usually leads to resource exhaustion and even extinction of species. As a result, the long-term usage of medicinal herbs should be considered, as should good harvesting procedures. What techniques and methodologies ensure that medicinal plant resources are conserved and used sustainably?
Relevant answer
Answer
In-situ and ex-situ conservation is the best solution for the conservation and sustainable management of medicinal plants but community awareness is also important. In most cases, the medicinal plants are collected by untrained or unprofessional local shepherds, plant collectors, some local traders, and even schoolchildren. They do not know even the plant part used as medicine and active ingredients and collecting/harvesting the plant's irrational ways like if the medicinal part of the plant is leaves, instead of collecting some leaves they cut the whole plants; if the active ingredients or medicinal part of the plant is root then they uproot the plant before seed setting which is the major reason of poor regeneration and sustainability of the plant resource in a certain area. There is thus a need first to identify the people who are involved in plant collection the to provide them training on the proper time of harvesting and collection techniques sustained without degrading the basic resources. There should be a clear-cut government policy on medicinal plant collection and trade following sustainable harvest and management principles.

In the context of accelerating the development of industry, global production, exploitation of raw materials, pollutants and waste emissions, increasing greenhouse gas emissions, accelerating the global warming process, protection of the natural environment, natural ecosystems, nature protection and biodiversity is one of the main challenges of the 21st century.
In view of the above, what do you think are the most effective methods, technologies, instruments for nature protection, natural ecosystems and biodiversity currently?
Please reply

Answer
Dear Mary,
Yes, I fully agree with you. Man-made greenhouse gas emissions are causing climate change, including the ongoing process of global warming. This process adversely affects the condition of the planet's biosphere, including it reduces the level of biodiversity of natural ecosystems. In addition, the deforestation process accelerates these unfavorable trends, which result in accelerating the process of global warming and the extinction of many species of flora and fauna. It is imperative to urgently carry out a pro-environmental transformation of the economy in order to build a sustainable, green, zero-emission zero-growth economy and a circular economy. The sooner this is done, the less degradation of the biosphere and climate will occur in the near future. This is a key goal of global environmental policy and to significantly reduce the level of future loss of biodiversity in natural ecosystems.
Thank you very much,

Question

I will be conducting a study that will determine which and how factors, such as biodiversity, influence urban green space quality, in relation to human psychological and physical health. In this process, biodiversity will be measured through the Simpson's Index of Biodiversity.
The initial rationale of choosing this particular index is that it calculates how diverse an area is (D). However, it would seem that this does not account for instances of biotic homogenization, or the introduction of non-native fauna and flora. Would there be other indices or measures that may quantify or at least account for biotic homogenization?
Any help would be appreciated. Thank you.

I appreciate your interest, although patterns of homogenization have been well studied, their specific ecological and evolutionary consequences remain unexplored. I know an article which has given a lot of good information. (https://doi.org/10.1016/j.tree.2003.09.010)

Answer
Dear Colleagues and Friends from RG,
Recently, positive trends have emerged that may confirm the thesis about the growing level of pro-environmental awareness of citizens. One example of positive trends in this matter is the growing percentage of citizens who do not buy live Christmas trees cut down for Christmas, but artificial trees or Christmas trees grown in pots from plantations. I am one of those people who do not buy cut trees, but buy growing Christmas trees in pots and then put them into the ground in a nearby green area. A dozen or so Christmas trees that I have planted are already growing in two urban green areas. I have noticed that there is a growing number of people who do likewise. Another example of positive trends confirming the growing level of pro-environmental awareness of citizens is the growing percentage of citizens who mow lawns less and less frequently, set up flower meadows and home gardens with flowers, including vegetables and fruit. Since in recent years the share of discounters and other large-format stores in the overall sale of food products and agricultural products offering highly processed products and agricultural produce mainly from large-area farms that do not apply the principles of sustainable, pro-environmental organic farming has increased, citizens more and more often buy agricultural products directly from farmers running farms applying the principles of sustainable, pro-environmental organic farming or establishing their own home gardens where they grow fruit and vegetables for their own needs. Pesticides and other chemical plant protection products are usually not used in the home flower and fruit and vegetable gardens. In addition, people who run this type of home gardens usually have a high level of pro-environmental and ecological awareness and therefore also apply other principles typical of sustainable organic farming. Another example of positive, pro-environmental changes confirming the thesis about the growing level of pro-environmental awareness of citizens is the growing percentage of citizens who reliably sort waste, and municipalities and municipal city cleaning companies are gradually expanding the number of fractions into which waste is sorted and conducting social, pro-ecological campaigns encouraging waste sorting. . Municipal cleaning companies of the city, in consultation with the municipal authorities, periodically carry out collection of waste sorted into several fractions of waste in individual city districts and permanently in designated places in the city. In return, citizens returning sorted waste receive flowers, potted herbs, bush seedlings, bulbs or seeds for flowers, herbs, shrubs, etc. More and more citizens are taking part in these pro-environmental campaigns to collect sorted waste. In this way, the habits of reliable waste sorting are strengthened and the scale of recycling, i.e. the re-use of raw materials obtained from sorted waste for the production of new products, is growing. Another example of positive, pro-environmental trends is also the growing share of pro-ecological investment projects submitted by citizens to the commune as part of competitions for investment projects implemented by the commune and financed under 1 percent. the so-called participatory budget of the municipal budget. More and more proposals submitted in these competitions by citizens concern the creation of additional green areas in urban areas and the organization and protection of already existing green areas, including city parks. In some communes, cyclical picnics and festivals for citizens are organized, during which pro-ecological educational campaigns for children, adolescents and adults are organized. During these educational campaigns, contests in ecological, environmental, biology, etc. are conducted. Such pro-ecological educational campaigns are carried out by municipal departments of environmental management, local libraries or associations and non-governmental organizations cooperating with the commune, active in the field of pro-environmental social campaigns. Since many aspects of these positive, pro-environmental trends have emerged in recent years, the question of the role of the SARS-CoV-2 (Covid-19) coronavirus pandemic in this matter, i.e. the scale of the pandemic's impact on improving the pro-environmental awareness of citizens, may be relevant.

Taxonomy (a branch of biology), for example, is a basic science discipline that primarily deals with the identification, classification, and nomenclature of plants. It also contributes to biodiversity and conservation. However, it has been largely overlooked in recent times due to the fact that it has been unable to grow broader impacts or, maybe, due to other emerging applied fields. This question is being posed to discuss the broader impacts of basic sciences in general, and taxonomy in particular.

According to the evaluations we have made among our colleagues on this subject and our own inquiries, another requirement has emerged. This means that there is a lack of standardization of the numbers used in the world's herbaria and given as the plant type codes. For example, for a plant samples of a species, collected from Turkey, stored in Geneva (G) herbarium, it has a different codes in other herbarium. For this reason, the species should be presented with the herbarium codes to be added to the country origin codes. Or some other digitising and coding systems. In this way, both the origin is indicated and even the collected plants can be classified. What do you guys think about it?
"TUR-G 125" instead "G 125"
Country codes are given below:
Relevant answer
Answer
The idea of standardising herbarium numbers is ill advised. Apart from the fact that it may create uncalled-for additional work if implemented retroactively, it may hamper the purpose of herbarium numbers which, usually, are accession numbers. There is some tradition, in smaller institutions in particular, for using herbarium numbers as a surrogate for collectors' numbers, which means that they are assigned to duplicate specimens as well, whether stored in the original place or distributed as gifts or on exchange. This leads to problems and errors; in particular, accession numbers are unique and can thus be cited in order to differentiate between duplicates, which is sometimes essential when it comes to type designation.
As an aside, there is already a system in place that is well known and widely used, which having been implemented in the JStor Global Plants images database (https://plants.jstor.org). It is not confusing and does not cause additional labour: it uses any existing herbarium numbers prefixed by the official "Index herbariorum" herbarium code (or "acronym"). The numbers are prefixed by the adequate number of zeros to match the longest extant (or foreseen) number used in that herbarium.

Hello,
This is for an undergrad paper I need to complete.
I am comparing the R^2 from a regression of 3 biodiversity measures: phylogenetic, functional and species richness to see which one is the best predictor of primary production.. Phylogenetic had a r2 of 0.28 and species richness had a r2 of 0.21, while functional diversity 0.077.
I was wondering if I could state from the r2 values that phylogenetic diversity was the best predictor? Since species richness had a r2 of 0.21, is it too similar to say phylogenetic is better than species richness?

How should the systems of nature protection and biodiversity of natural ecosystems be dispersed in order to increase the effectiveness of these systems and reduce the scale of degradation of the natural environment?
What do you think should be improved in nature conservation systems and biodiversity of natural ecosystems in addition to just increasing financial outlays on nature conservation policies conducted by government agencies and ministries of the environment?
A significant part of financial expenditures of nature conservation and biodiversity policy is devoted to the promotion of nature protection and natural environment protection issues. However, the effectiveness of this type of promotional campaigns is low, because without applying legal restrictions, enterprises do not change their technologies to be more ecological if they do not see in this business realized in a short time. Even the occasional UN climate summits in which government representatives from the majority of countries take part do not cause significant real changes in the policy of nature protection and biodiversity? Usually, the largest industrial economies in the world do not sign the obligations of rapid reduction of greenhouse gases and the issue of increasing spending on environmental innovation in the energy sector. Why, despite the growing scale of public awareness, there is no significant improvement in the implementation of nature conservation and biodiversity policy, there are no real measures that would result in a significant reduction of greenhouse gas emissions and the slowing of the global warming process?

Dear Roman Bohdan Hołyński,
Thank you for your response. Yes, of course population growth has been going fast for hundreds of years. This issue has been pointed out since the beginning of the first industrial revolution in the 17th and 18th centuries. We now have the fourth technological revolution, the problem is many times larger and still the same questions. Until now, technological progress, including in the field of new technologies increasing the efficiency of agricultural production, has solved the problem of feeding the rapidly growing population. On the other hand, however, in the least developed countries, the scale of poverty and food shortage is becoming a rapidly growing problem. In addition, climate change causing droughts, forest fires, soil barrenness, pest infestations etc. exacerbate these problems. Until recently, technological progress seemed to solve the key problems of the development of civilization. However, in recent years there has been more and more evidence to challenge this thesis. If the process of global warming accelerates in the next decades, the above problems will quickly worsen and the technological progress will become insufficient to solve them. Therefore, our view on this issue is very similar.

My problem is I have quite a solid dataset that highlights patterns of responses to droughts in 2003 but when it comes to the 2018 data I only have the hydrological data but Biotic data was only collected again in 2020. So there is a 2-year Biotic gap.
The 2020 biotic data does somehow fit my hypothesis but without the response Due to lack of data, it's hard to write about it in any way that doesn't take too many liberties.
How does one go about writing about the inferred response in this data gap in a meaningful way?
Relevant answer
Answer
You can apply data imputing, or missing data imputation. A simple approach is to use statistical methods to estimate a value from those values that are present, then replace all missing values with the calculated statistic.There are also machine learning or random forest algorithms and packages that allow correlations over time and can automatically detect and deal with missing data :)

The World Environment Day 2020: Call for Book Chapters
Dear Colleagues,
Greetings of the day!
The World Environment Day (WED) is commemorated on 5th June of every year to promote awareness about the importance of conserving the environment for our better future and sustainability. The foods we eat, the air we breathe, the water we drink, all comes from nature. We are entirely dependent on nature’s services. The theme for this year’s World Environment Day is biodiversity. The more biodiverse an ecosystem is, the more difficult it is for one pathogen to spread rapidly or dominate; whereas, biodiversity loss provides the opportunity for pathogens to pass between animals and people. Human actions, including deforestation, encroachment on wildlife habitats, intensified agriculture, and acceleration of climate change, have disturbed the delicate balance of nature. We have changed the system that would naturally protect us and have created conditions that allow particular pathogens–including coronaviruses–to spread.
I am delighted to inform you that the Faculty of Applied Sciences, AIMST University is going to publish a book to commemorate the World Environment Day-2020 (WED-2020).

For two populations A and B, there are situations in which there is a two way exchange of individuals between the populations, and there are situations in which there is no exchange of individuals between the populations. I have thought before of a situation involving one way isolation between two populations, in which it's easy for individuals from population A to immigrate to population B, but impossible for members of population B to immigrate to population A.
Are there any examples of the one way isolation I mentioned between populations?
Any example for marine populations?
Do you know the names of any of the specific species that would be examples of this?

Hola estimado Dr. Abdiel.
Tiene un punto muy interesante de discusión. Un caso tan específico como el que mencionas sólo lo he leído en insectos como Prodiplosis longifila y sus hospederos. Puede ver este caso que menciono en este artículo:
Por otra parte, en organismos marinos, el hecho de que los individuos de la población B no migren a la población A, podría ser raro, dado que las corrientes marinas y otros factores naturales (ejm. huracanes, sustratos flotantes, etc.) en teoría deberían facilitar el libre paso de individuos (sobre todo me refiero a macroalgas, que son los organismos con los que he trabajado). Sin embargo, el istmo de Panamá, por ejemplo, es una barrera efectiva que pudo generar vicarianza o especiación alopátrica en muchas de las especies marinas que conocemos, hacia el caribe y pacífico oriental tropical. Al menos, en rodófitas como en Bostrychia y Polysiphonia, entre otras, y sobre todo en los ambientes de manglar en los que prosperan (o incluso en corales), esto podría ser viable, pero requeriría de comprobación filogeográfica. Esto lo menciono, porque he encontrado muchas especies de macroalgas en ambas costas de Colombia, pero no sabemos cómo ocurrió el paso de estas poblaciones de algas y el efecto del istmo de panamá en este proceso. Además, el efecto localizado de la dispersión de esporas en istmos, bahías estrechas, con estuarios poco interconectados, o con impacto antrópico, podría eventualmente limitar la migración de una población B a la A.... Me llamó la atención el tema que propusiste, y ubiqué unos artículos en algunas especies marinas en las que puede existir evidencia sobre tu pregunta. Te dejo por acá los links de los artículos, por si te interesa profundizar el tema. Un saludo cordial, Diego:

Globally, there are more than 45,000 large dams in operation in over 150 countries and another 1500 or so are currently under construction according to World Wildlife Fund (WWF). Dams and weirs have been built on rivers (a barrier across a river) to achieve a number of benefits including water storage, irrigation supply, drinking water, preventing floods, navigation, hydroelectricity production, and recreation etc. In recent time, most dam construction is taking place in the developing world, such as in China and India. 46 new large dams being planned or under construction in the Yangtze River basin in China; 27 in the La Plata basin in South America; 26 in the Tigris and Euphrates Basin in Turkey, Syria and Iraq. Dams are also planned on three other rivers: the Salween in China, Thailand and Myanmar, the Kizilirmak in Turkey, and the Ganges in China, Nepal, India and Bangladesh.
The development of engineering infrastructure such as dams and weirs over rivers has modified rivers ecosystems threatening the water quality (e.g. salinity, cold water pollution) and water dependent biodiversity (e.g. native fish). Dams disconnect rivers from their flood plains and wetlands, reduce water flows in rivers, and affect the migratory patterns of fish. In general, water retention by dams eliminates or reduces spring runoff or flood pulses that often play a critical role in maintaining downstream riparian and wetland ecosystems including the lifecycle of fish. Older dams release water that is stored at the bottom of the dam, which is typically colder and adversely affects species adapted to warmer temperatures. Such an effect is sometime referred to as ‘cold water pollution’. The construction of a dam on a river can block or delay upstream fish migration between feeding and breeding zones and thus may contribute to the decline and even the extinction of species. As a consequence of dams, for example, some unique species and habitats are/will be threatened including freshwater native fish, river dolphins, porpoises and water birds. One estimate reveals that dams and associated uses of water have altered two-thirds of the world’s major rivers.
In Australia, the Federal Government Department (Commonwealth Environmental Water Office) has acquired/is acquiring water with the goals/objectives to increase water flows in rivers and wetlands (commonwealth environmental water). Reduced flows in the Murray Darling Basin (MDB) have already caused environmental problems (increased salinity, increased algal blooms/cyanobacterial blooms, decline in native fish and bird populations and poor wetland health). This environmental water has been/is being recovered through water saving infrastructure upgrades, water purchases (direct buybacks of water entitlements from irrigators) and other water recovery programmes in order to protect or restore the environmental assets of the MDB. The environmental water will help protect and restore the resilience of the MDB’s rivers, wetlands, floodplains, lakes and red gum forests, together with the plants and animals that depend on them. In a number of countries (e.g. third world countries), people may not be familiar with environmental water or environmental flows and a need for environmental water for biodiversity.
Question: Do you agree that there is a need for environmental water/environmental flows to protect biodiversity where dams have been built or to be built? If so, how can we achieve a balance between water usages for consumptive purposes (drinking water, industry and irrigated agriculture) and meeting the demand for environmental flows for smooth functioning of river ecosystems and river biodiversity?

Due to the current civilization progress in recent decades, acceleration of the development of industry, automotive, urban agglomerations, intensification of agricultural production, etc. and related greenhouse gas emissions, global warming, ozone layer depletion in the atecologicalecologicalmosphere, increase of environmental pollution, growing problem of smog in urban agglomerations, the increase in pollution of the seas and oceans to which unsorted waste is thrown away is cut out as part of the predatory economy of tropical forests in the Amazon and other largest natural forest ecosystems.
In addition, the secondary effect of global warming of the Earth's climate is the increasing, more frequent weather anomalies, including drought, leading to steppe and desertification of areas that were previously natural forest ecosystems or areas exploited by agriculture.
As a result of the above-mentioned processes, every year many species of flora and fauna disappear forever.
As a result, natural biodiversity diminishes, which for millions of years evolved evolutionally on Earth.
In this way the natural resources of the planet Earth are irretrievably in decline.
In view of the above, the issue of environmental protection and biodiversity is one of the most important challenges of humanity in the 21st century.

The Amazon rainforest is the largest complex of the natural forest ecosystem of the planet Earth. The Amazon rainforest it is a natural complex of forest ecosystem with rich biodiversity. In these Amazonian ecosystems there are still many, millions of species of flora and fauna that have not yet been fully discovered or described.
The scale of felling and thinning stands in the Amazon's forest is so large that every day the scale of this unique biodiversity decreases and many species of living organisms cease to exist.
Human civilization in this way destroys one of the greatest achievements in the development of life, the evolution of ecosystems on Earth.
This is a very serious problem to solve in the 21st century.

However, in this time of global biodiversity crisis, we are constantly confronted with prioritizing. Recently I read somewhere that in the Arctic, the photosynthetic algae should be taken care of and not the polar bears. Also in temperate regions, where the habitats are under enormous pressure, shouldn't we pay the greatest attention to the producers/plants? On the local level (local administration, journalists) I am constantly confronted with the question: who do we save first?

MDE (mid-domain effect) was proposed in 1994 by Collwell and Hurtt, and was subsequently studied deeply. There were also strong criticisms of MDE (Zapata et.al. 2005; Hawkins et al., 2005). In 2009 Collwel et al. wrote: "Like any idea that calls for an entirely new way of looking at an old problem, MDE has, at times, been either too quickly embraced or too quickly dismissed, but has generally met with appropriate scepticism and gradual acceptance".
The statement above does not seem very clear. If one looks at studies of diversity gradients incorporating MDE, there is a rather clear picture. Almost all studies in which explanatory power of MDE was detected it accounted for less than 50% of variability (which is quite low). On the other hand, many studies showed that MDE has no importance (e.g. Aliabadian & Sluys 2008), or that it is correlated with other variables such as climate and says nothing additional (e.g. Kessler et al. 2011). In addition, the relationship between MDE and diversity distribution is inevitable at some degree and this relationship grows in strength as the pattern approaches a perfectly symmetrical hum-shape distribution.
I have an impression that MDE is just a wasted time. Is this true?

Protection of the environment, natural ecosystems and biodiversity should be an integral part of the concept of sustainable pro-ecological economic development?
In the context of growing and increasing environmental pollution and declining areas of natural ecosystems, the importance and need to improve environmental protection systems, natural ecosystems and biodiversity is increasing. Biodiversity is one of the most important issues of natural ecosystems and life on Earth. Maintaining high biodiversity on Earth should be a challenge and one of the main goals of human functioning on the Earth in the 21st century and in subsequent centuries.
In connection with the above, protection of the environment, natural ecosystems and biodiversity should be an integral part of the concept of sustainable ecological development. In some countries, the concept of sustainable pro-ecological economic development is implemented successively, primarily in the field of renewable energy sources, improvement of waste segregation techniques and recycling development. However, in many countries these issues are still insufficiently developed.
Still too small financial resources are allocated in many countries for the development of renewable energy sources, improvement of waste segregation and recycling techniques. In addition to the private sector, besides enterprises implementing ecological innovations, it is necessary to increase expenditures and develop strategic pro-ecological reform projects, including restructuring of the mining industry of minerals supplying classic energy sources and development of energy based on renewable energy sources. This development should be supported and coordinated by environmentally friendly state intervention, and due to the high investment costs of construction of power plants producing electricity from renewable energy sources should be co-financed from the state public finance funds.
In this way, it will be possible to slow down the ongoing global warming process in the 21st century and thus slow down the process of devastating the natural environment, draining green areas characterized by high biodiversity. Biodiversity is a very important issue in the context of the analysis of ecology, sustainable development and the protection of the natural environment, including, in particular, the natural positions of biologically complex ecosystems, i.e. those that are characterized by high biodiversity. Maintaining biodiversity of natural ecosystems is one of the most important problems and tasks for people in the 21st century.

Biodiversity is diverse in virtually unlimited degree, which results from the essence of processes of evolution of species, filet lines and entire ecosystems. It is thanks to the millions of years of evolutionary processes on Earth that there are so many different natural and highly diverse ecosystems in which different species of flora, fauna, fungi and microorganisms adapt to life in different and very diverse geographical and climatic environments.
The largest biodiversity of ecosystems and species functions in natural environmental environments in which ecosystems have evolved without human impact through millions of years of climatic and geographical conditions enabling the development of various life forms. These types of high biodiversity sites can be found in unpolluted rainforest ecosystems in tropical forests, in temperate climates and in coral reefs.
Unfortunately, human civilization activity contributes to the successive and accelerating process of biodiversity reduction by dying out species of living organisms. The areas of natural natural ecosystems are decreasing, including those in which the greatest biodiversity is diagnosed, such as the rainforests of the Amazon. The protection of naturalistic ecosystems and thus the protection of the planet's biodiversity is the most important challenge for mankind in the 21st century.

There are several options for improving the institutional framework for biodiversity incentives:
(1) decentralization of resource management decision making to local levels
(2) engaging and reorienting government institutions
(3) establishing new national and international institutions
(4) establishing functional linkages between key institutional actors
Are you agree with this? any more to add?
Relevant answer
Answer
This is an interesting topic of discussion, but I fear it is not possible to make great extrapolation of advice from one place to another. Decentralization of resource management decisions to local levels, for instance, seems fine and make sense. But, it can be a double-edged sword, as highlighted by Girma Kelboro. Local people is usually much more aware of their needs and the resilience of local environment to disturbance (for instance). However, local authorities are much more exposed to conflicting pressures with other local actors. In many developing countries, where most struggle for biodiversity is concentrated now, people who act outside the law (deforesters, garimpeiros, drug dealers) often have the means to coerce by the threat of violence or are more likely to corrupt local minor authorities in the front line, which can end up decreasing law enforcement. In these cases, decision making centered at federal institutions may be more resistant to these pressures. Anyway, a leadership committed to conservation can make a big difference at any level (as mentioned by R.T. Corlett), but a great leadership at national level is invaluable. The disaster of the environmental administration of Brazil under way is a sad example. They are acting specially in your points 2 and 4 in a bad way.

When talking to visitors of our museum/zoo, some of the most frequent questions asked are "Why is keeping species from going extinct an activity worthwhile to pursue?" or "Why does it matter if this midge or that tick is going extinct?".
While most biologists will probably reply that species have very specific roles in their ecosystems and thus the extinction of one species can probably affect others, too, or that each species is part of the richness of our nature (a value in itself so to speak), some non-biologists are often not that easily convinced (especially when you refer to species not very attractive to the human eye). What even more hampers an easy answer is that more than 99% of species that ever existed have died out in the course of evolution. So what is all that conservationist effort, to 'preserve the current state' all about? Changes in biodiversity and mass extinctions have always happened, so why don't we let it just happen now (to put it insensibly)? There are also some human related arguments, for example "we breathe air and thus need plants of some sort". But that does not mean I need every plant species on the planet to produce oxygen, crops will do that, too...
I would like to hear your thoughts on this to have some good arguments at hand when dealing with the next inquisitive visitor. ;-)

A watch can work without the glass covering the clock face. A watch surely can work removing one of the tiny gears from the inside. And will probably still work if you remove a different tiny gear instead the one we mentioned before. You can also wet a bit the clock, and hopefully it will work without much problem...
But a watch will probably fail if we remove too many pieces or damage it too badly... And then you will have to buy a new one.
So, the World is a watch, and biodiversity are the gears that keep it moving.
How many pieces we want to remove or how much damage we want to apply to see if it stop working?
The problem is that buying a new World is not in the immediate schedule!
And so, that is why conserving biodiversity matters.

Hello,
is it possible to use the linear discriminant analysis (LDA) to determine which of the analyzed variables best separates the different groups (which are already known)?
For example, I want to understand how 3 different croplands are different in terms of ecosystem services provisioning. So, I decide to measure 4 variables for each ecosystem (Soil Carbon, Dry matter, Biodiversity, and GHG) and then I run an LDA analysis (on PAST 3.4 here)
I get this result (see the attached picture). Here clearly the Grassland seems to be more different than the other two croplands (because it is more displaced than the other two croplands on the X-axis).
Would it be correct to conclude that this grassland differs most from the other 2 crops and this seems to be determined by its level of biodiversity?
Thanks (and of course, these data are not real. That's just an example)

Hello Matteo,
It would be correct to say that the centroid (mean on the linear composite of the variables forming the first discriminant root or function) for the grasslands group is further from the aggregate (all cases) centroid, or from the centroids of the other two groups. However, the display doesn't inform you as to what variable(s) are most influential in the function.
For that, you'd have to look at both: (a) standardized function coefficients, and (b) variable-function correlations (sometimes called loadings or structure coefficients). If variables are uncorrelated, then standardized function coefficients alone will let you know the relative magnitude of emphasis being placed on each variable in the function. If correlated, then you have to look also at loadings to be sure that you're not letting collinearity confounding your interpretation of relative emphasis as also indicating importance. So, the information presented isn't enough to presume that a single variable (biodiversity) is the reason for the separation in group centroids.
Good luck with your work.

Hey guys, I've been working on a project with my research mentor where I have been delineating watersheds at biological collection sites along the Cahaba River (near Birmingham, AL, an urban area) using ArcGIS, and using these watersheds as "cookie cutters" to cut out a shape of US Land Use data from the USGS. We've been doing this in order to quantify how land is used within the watershed of each site. When I process these data with the biodiversity data derived from each collection event in R, the AIC indicates that Urban Cover within the watershed (as opposed to Agriculture, Grassland, and Forest) best predicts biodiversity, even well away from any urban center. While my project mentor and I think this makes sense (sites further down the river seem to have highest biodiversity, as well as higher Urban Cover), we can't see any other trends. We've tried using river miles from the mouth of the Cahaba and catchment size to see if we can keep Urban Cover constant and find other trends, but AIC still favors Urban Cover as a predictor. Is there a way that we can hold Urban Cover as a constant, so that we can search for trends elsewhere within the data? Would really appreciate your input.

Can you share any interesting photo concerning butterflies you'd met in nature in your country or during your voyages abroad?
Can you also comment it shortly with a place and date you'd spot it? Also its name. If you are not sure you may ask other participants about the specy name, instead.
E.g.: In May 2019 I'd spend my holidays in Greece, and met there the above Epicallia villica, the cream-spot tiger, a moth of the family Erebidae.
