Questions related to Wildlife Conservation
I am facing a problem that I cannot solve at the moment. I want to calculate a population size (small mammals) and my choice fell on the Jolly-Seber model. Everything is clear as far as the calculation is concerned. My problem at the moment is the data. The season is from April to October. During this time, traps are set and nest boxes are checked at undefined intervals (but the nest boxes are always checked monthly). The animals are tagged and released. My data range from 2019 to 2022.
The problem at the moment is the data base. Do I calculate the population size from survey to survey, e.g. April 2019 to May 2019, then from May to June, from June to July and so on, or can I calculate from year to year? Then I could look at how many individuals were captured and tagged in 2019, how many of those individuals were recaptured in 2020, how many were added in 2020 and so on until 2022.
Then I could theoretically calculate the population size from year to year or based on 2019 (which individuals from 2019 were also captured in 2022?).
My question is whether this calculation is possible from year to year or whether I have to calculate from session to session within a season? Between the seasons is winter, during which the animals hibernate. An individual caught in 2019 could be caught again in 2022!
Calculating from year to year seems to make more sense to me and is much more bearable, especially when preparing the data - although this plays a subordinate role.
Thanks in advance.
The local human cost of wildlife conservation
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?
I need the names of the top journals related with wildlife conservation or birds.
The world is changing and humans are the main reason for the change. Because of human activity, we are heading into the sixth mass extinction. The human population is growing very fast and now if we take any radical step then the whole system will collapse. Though for Wildlife conservation we need to make bold steps.
So how successful we will be in wildlife conservation?

I’m looking for literature/advice regarding how to implement a bird survey (abundance/density estimation) in areas/habitats with dense vegetation and rough terrain, like tropical rain forest. It seems to me, that point-counts are the method that best fits such conditions. However, what kind of sampling designs should I implement in order to meet the statistical requirements? That is, in very mountainous areas locating the points randomly or systematically (neither there is apperent stratification) seems almost impossible because of the logistical difficulties of accessing and locating the selected sites. The only viable alternative seems to be to follow trails already present in the area and to locate the plots (with a first random point) along the paths, every 250 m or so. Additionally, I think that some points can be located at both sides of the trails (walking 250 m on either side of the trails may be feasible at some points). However, this “design” seems to violate the assumption of randomness in selecting the sample units. Any comments or suggestion of alternative design will be welcomed.
Hi, I am a Biodeserts PhD student working on socio-economics in deserts. We developed a survey about wildlife conservation and community development in Sahara-Sahel, North Africa. We would be very thankful if you can answer the survey and share it among your family and friends: https://forms.gle/T2FkYpMEfhU9o8gFA.
In this case, forest rangers (Respondent 1-Quantitative Data) and local community (Respondent 2-Qualitative Data) in a protected area.
Aware that managed breeding is still a controversial issue, I believe that one conservation endeavor should not discard the other or worse, antagonize the other based on personal opinion or theoretical discipline gain. In situ and ex situ have both proven to be necessary to avoid extinction of critically endangered species.
I could cite several examples but one should be representative for all: the Arabian Oryx (Oryx leucoryx). Extinct in the wild but some individuals breeding in Zoological Parks. Today the Arabian Oryx is reintroduced successfully in former range areas and numbers in the wild are increasing. Why leave managed breeding as "the last resource"? And when is the time to put in action "the last resource"?
There are conservationists who cannot tolerate the extinction of a species for anthropogenic causes and believe that intervening on specific species is a responsibility. There are others who consider a species better extinct than detached from its habitat, even partially. Discussion can go on forever…but no one can ascertain the future of our Planet with 100% certainty and state which solution is the best.
Hi! I am working on bats. I am eager to mount low cost, light weight, long battery life navigation devices. I will also mount ibutton temperature and humidity sensor along with navigation device. The purpose of attaching navigation and temperature sensor to bat is to 1) measure temperature at the level of bat in the canopy of roost tree. 2). navigation device help recover temperature sensor in case temperature sensor is lost and also help track bats foraging areas. Requirement for temperature sensor and navigation device is 1) light weight (20-40gm) Measure temperature (-20 to+80) Humidity Measurement (95% RH to 100% RH) Extended battery life (>5 Years). I found out these devices Remora 2 (GPS 4G) https://www.digitalmatter.com/Devices/4G-GPS-Tracker-Devices/Remora2 and Ibutton Temperature Senor https://www.embeddeddatasystems.com/DS1923-F5--Hygrochron-Temperature-Humidity-iButton_p_101.html
Please suggest any better option for meeting my research objectives?
Consumption of wild animals is bound with the rural economy in developing countries. Sometime, demand for Wild Animal Foods (WAF) is very high in developed countries too.
However, experts think the Coronavirus transmitted from live animals to human through the food. If this is a truth, impacts of consumption of wild animals on Global Economy is significant, and enforcement of lows at international level is essential to control this.
I would like to discuss about the feasibility of enforcement of lows at national and international level to control WAT.
I have an issue and I'm hoping you can give me possible solutions or some advice. I, and two other co-authors, had an accepted paper (since 2019 October) in a great wildlife journal that has an open access condition (== it is necessary to pay a fee). At the time of manuscript submission, I was in another institution that was willing to pay my fee slice (1/3, == U$ 520). Now, I'm in another institution that doesn't have this kind of support. I now have 2/3 of the fee, I contacted the journal and explained all this, and they don't care (in fact). So, we are now wondering to change the manuscript submission to another journal (without needed payment) and start the process all again. We did not sign any license yet. (1) Could you indicate a wildlife journal with not too long a submission process? (2) Do you think if I wrote that it was an accepted manuscript in the cover letter the process could be shorter?
Thank you all
A general discussion on the approach to making children aware that wildlife is on the verge of extinction, and what their generation can do to try and slow this process
The Apo Island conservation project is an example of how a scientist was able to work with local fishermen to educate them about the need for a marine sanctuary. Details at:
I want to measure the relative usage of riparian corridors and measure how pressures, like vineyards and vineyard fence types, outside the corridor affect the diversity and density of the wildlife species using the corridors.
The types of vineyard fencing being: high exclusion, no fencing, and whether we can determine how trellises affect diversity, density, and use.
My advisor wants to know how I'd tell who is migrant and who is a resident.
Other than visually, using genetic testing, or tagging, I'm not sure how I'd be able to determine who was a migrant using the corridor and who found it to be a suitable habitat (enough to reside there permanently). A friend of mine said mentioned a statistical analysis one can do that basically assumes who falls into what category, but I can't find an example of the analysis.
Anyone have some ideas? It would be greatly appreciated.

Recent scientific literature refers to the North American elk (wapiti) as either Cervus elaphus or Cervus canadensis. Has this debate been settled?
I am looking for incidents of this behavior in the literature, or from government agency reports. Links and citations would be most helpful.
I need to calculate phylogenetic diversity (PD) of many different areas. I found some ways to calculate it, but couldn't decide on which way is better. If anybody has any idea about it please let me know.
I am seeking statistics on the frequency of bat deaths associated with wind turbine operations. I am also seeking information on the type of features associated with high rates of bat mortality, any regulatory setbacks or other measures to reduce mortality and the efficacy of mitigation measures implemented to reduce mortality like reduce cut-in speeds.
I'd be happy if you could point me towards literature that develops models with macroeconomic variables and an explicit representation of biodiversity, or at least one representative species.

Are there papers or studies on conservation vs. conservation conflicts and how to avid and/or manage them? Here in Bulgaria we have at least two such conflicts, where actions to conserve one conservation dependent species are not in favour to other or even worse may further threaten it. For example conservation of the wolf in Bulgaria (especially legislation changes) could lead to illegal actions against wolf (e.g. poison baits use), which do not affect the wolf that much, but are absolutely dangerous to vultures and eagles. This conflict passes through the man-wolf conflict though. The other example is the conservation of the European Suslik (Spermophilus cittelus), which requires well grazed (even may be overgrazed) grasslands to recover and sustain and its conservation, restoration and abundance is fundamental for several other species (e.g. Saker Falcon, Imperial Eagle etc.), but the general nature lovers and botanists are against heavy grazing and keeping grassland in best condition for Susliks. So here is a Conservation-Conservation conflict. To may opinin it should be measured on the base of Conservation value of the species involved, which is not always the case e.g. managers of the Central Balkan National Park in Bulgaria. Any references, notes or discussion will be appreciated.
i have a plan to publish my manuscript in field of volunteering in wildlife and conservation education. I need a (some) collaboration. if you run with this issue, feel free to contact me.

I'm writing a report for an assignment on the animal welfare issue regarding the rehabilitation of grey squirrels here in the UK. I'm trying to find sources of information from both sides of the argument and one point that I'm struggling to argue for is why we should, one of the points I'm trying to elaborate on is this question.
I am currently investigating how the abundance and diversity of food arthropods of sage-grouse are influenced by various land uses. Ultimately and as land management tools, I would like to generate some predictive models (as simple as possible) which use site characteristics (i.e., plant species, bare ground, sagebrush, etc.) to assess food arthropod abundance and diversity. I am looking forward to hearing any suggestions on how best to approach this research topic.
Are there examples from Europe where winter feeding of red deer has been reduced or eliminated? North American elk (Cervus elaphus) have been fed supplemental hay rations during winter months at the National Elk Refuge (NER) in Jackson Hole, Wyoming since 1912. We are exploring options to reduce reliance on supplemental feeding at NER, but there are very few examples in North America where this has been attempted. Any information from Europe where winter feeding of red deer has been reduced or eliminated would be appreciated.
In my research activity I am increasingly including the analysis of Ecosystem Services and their perception. Indeed, despite having studied dozens of papers and grey literature during my student career, I have found few textbooks. I am looking for a text that summarizes the state-of-the-art about ES and the techniques for their monetary and non-monetary evaluation. Is there any?
I am aware that some sort of mats are used but what kind and where would i find them?
These samples are meat balls with some structures. The idea is someone that work with taxonomy of caterpillars. I have photographies of these samples and if someone have interest, I could send these images.
I am interested in how to classify activity measurements from GPS collars for kangaroos.
I'm trying to ascertain the actual rate of morbidity/mortality resulting directly or indirectly from the use of instrumentation on free-ranging animals. Most 'negative' results are not published. I'd like to assess the scale of this gap in our knowledge to improve procedures. If anyone has anecdotal information or can suggest sources I'd be very grateful. Thanks.
So far I have some estimates from Lotek, Holohil Systems, and ATS. I would love to hear personal experiences about these and any other company's products.
I'm also curious if anyone has some insight into tracking a species that is known to burrow in mud and how the signal might work...

I am designing a study on how to establish a carrying capacity of an isolated habitat for the African elephants. The habitat support also the existence of giraffes, bushbucks, sitatunga, suni antelopes, chimpanzees, ververt monkeys, and black and white colobus monkeys. I need to know what are parameters required to be known and associated models. Welcome for improving my study. Thanks.
I'm looking for published and unpublished informations on the effects on wildlife of the existence or creation / expansion of airports (apart from the bird strike problem). I'm especially interested in the consequences produced by the noise, air pollution and the existence of a network of roads connecting the airports on the density and reproductive success of animals in the surrounding areas. Is there anyone who can give me any suggestions?
I would like calculate the percentage that it represent (extinction by hunting as unique or fundamental cause)from the total worldwide biodiversity
I would like to start to capture Myocastor coypus on its natural distribution, but I found few detailed references on how to deal with the animal in the field. Some information regarding traps size will be useful too.
I need to code the hairy-footedness of a large number of rodents for a statistical analysis. In most cases it is simple enough to code hairy-footed species as 1 and naked footed ones as 0; however, the following five species are described as intermediate in hairy footedness in different references. Furthermore, they are intermediate in different ways and to different degrees (see the description below), so each has to be considered separately. If I had to do a binary coding for this character, what is the more reasonable value (0 or 1) to be assigned to each of the species?
Gerbillus nancillus: “Soles of hind feet partly naked behind, with short hairs at level of the metacarpal bones” (Mammals of Africa, Kingdon et al, 2013) — "It is a relatively small gerbil with partially furred soles (posterior portion naked)", "an almost naked hindfoot sole (it is only partially haired in G.nancillus" (Mammals of Sub-Saharan Africa, Monadjem et al, 2015) — "Intermediate" (Lay, 1983)
Gerbillus nigerae: “[S]oles of hindfoot covered with hairs of variable length” (Mammals of Africa, Kingdon et al, 2013) — "These last three-mentioned species [G. henleyi, G. nancillus, G. nanus] also have naked or semi-naked soles of the hindfeet, which are completely haired over along their length in G.nigeriae" (Mammals of Sub-Saharan Africa, Monadjem et al, 2015) — "Intermediate"(Lay, 1983)
Meriones shawi: "Soles of hindfeet partly hairy" (Mammals of Africa, Kingdon et al, 2013) — “The sole of the hind feet is half covered with very fine fur” (Darvish, 2011)

Gerbillurus vallinus*: "Hairy footed gerbils" "soles partially furred" (Mammals of Africa, Kingdon et al, 2013) — "the anterior soles of the hindfeet are furred" (The Complete Book of the Southern African Mammals, Mills and Hes, 1997) —“Soles of hind feet of G. vallinus are naked from heel to the middle of the sole” (Dempster et al, 1999)
*I know it is called the brush-tailed hairy-footed gerbil, but unlike the other congeners that I have looked at the back half of the foot is described as naked).
I am interested to undertake a study on determination of level of inbreeding in elephant population in an isolated habitat. The nature of study area is thick forest, hence collection of fecal samples is the relevant approach to study Genetics of elephants.

Considering C-hat adjustment when looking at occupancy modelling analysis.
Every day a vernacular landscape dies. Every day, the abusive exploitation of land is literally erasing the landscape so its occupants can no longer live from the land. This situation has provoked, among other things, the massive migration of refugees, the crisis in the quality of air and water, the downgrading of nourishment and wellbeing in general. Can we, as scientists, come to the rescue? How? What would you suggest to do on the small scale of your immediate community, or on behalf of humanity at large? Let's dream and then create together a plan of action, or many plans, according to the knowledge, discipline and training of each of us.
Below is a brief anthology of sharp and diverse definitions of landscape/nature to focus our reflection from diverse points of view.
Hey! I'm an optimist! Let's get to work together!
Conference Paper Landscape: A Treasury of Definitions
I am interested in reviewing the topic of small mammal mortality within discarded bottles, and information available is severily biased towards the northern hemisphere and in developed countries (USA and Western Europe). Does anyone has information from tropical areas? or from other continents?. This is surpising to me, because I know that discarded bottles is a aproblem worldwide (result of human development). There is information of discarded bottles as a potential source for some diseases like dengue or malaria (the rain water contained in bottles allow mosquitoes to lay their eggs). But nothing about small mammals dead inside bottles.
Dear Researchers and Academics;
I work on the 100% renewable power Global Grid subjects. I am interested in the locations of very large and large renewable power plants.
During my research, I define and describe the importance of the soil conservation regions, water conservation regions and forest conservations regions. These regions have to be untouchable (no settlement, no concrete, no metal, etc.; soil conservation only for agriculture, water conservation only for clean fresh water, forest conservation only for forests). These regions should be large and very large sites.
I thought and assumed that the international governing bodies (e.g. the United Nations) had already worked on these topics, defined, decided, and published a Global Soil Conservation Map (worldwide protected sites), a Global Water Conservation Map (protected lakes, rivers, underground water, etc.) and a Global Forest Conservation Map (protected forests) for large protected areas agreed upon and published by international consensus (like by the United Nations).
All authorities (regional, national, international) have to obey the borders of these defined and published large protected areas.
I could not find any official map (a map for soil, a map for water, a map for forest) yet.
Can you please send me a Global Soil Conservation Map, a Global Water Conservation Map and a Global Forest Conservation Map, if there is one for Global Soil Conservation, one for Global Water Conservation and one for Global Forest Conservation.
If there are GIS files for these maps in some formats such as for Google Earth, ESRI ArcGIS, they will be very useful for my research.
I would like to thank all of you who contribute to this question in advance.

Poachers and wildlife traffickers are targeting newly discovered species of value by reviewing reported findings made to scientific journals. In response, many journals are removing location details from papers.
If a tagged fish is predated by another fish, for how long time is the tag retained in the stomach of the predator? Are there any published studies? Anything on salmon smolts and in-river predation?
The shift in production of Crocodilian skins from all wild harvests in the early 1980s to captive breeding and ranching in the late 1990's is often hailed as a massive conservation success.
However recent data shows that since 2004, wild harvests have massively increased to around 400,000 in 2012, whilst ranching has fallen to around 50,000 and captive breeding remained around 900,000.
Does anyone know why this is as I have struggled to find an answer in the literature? Focus seems to be on the trade pre 1999 before wild harvests began to increase again.
I have been using the IUCN website (http://www.iucnredlist.org/) recently and they claim to be the largest conservation organisation in the world. Does anyone have any idea as to their effectiveness?
Aside, does anyone have any ideas as to the appropriateness of the Red List Categories (EX, CR, VU, etc.) and their respective criteria? If anyone has any ideas for any additional criteria or any alterations they feel appropriate, I would be very interested to know.
Thank you for the help in advance!
I’m hoping that some of may you have experiences on fallbacks and if there are any mitigating actions to be done, that you would like to share. We have done a study on early vs late migrators and seen that the fallback rates are much higher among the salmon in the early run. Now, the fish are released, after being caught in a fish trap at the first powerplant and then trucked passed them, about 20km above the dam , and the fish I call fallbacks then turn downstream and pass or dies at the powerplant. Is there anything to do? Would it help to release them further up? Or keeping them in a bag for a while before releasing them? Or would a fence or diverter work?
Example of a case study : When the "Grey wolf" was reintroduced into the Greater Yellowstone Ecosystem in 1995, there was only one beaver colony in the park, said Doug Smith, a wildlife biologist in charge of the Yellowstone Wolf Project. Today, the park is home to nine beaver colonies, with the promise of more to come, as the reintroduction of wolves continues to astonish biologists with a ripple of direct and indirect consequences throughout the ecosystem. Cases of how the re-introduction of wolves , changed the river patterns significantly, is also a remarkable study!
Shuklaphanta Wildlife Reserve (SWR) (305 sqkm) of Western Nepal, as a part of Terai Arc Landscape, the global priority tiger conservation landscape, has a significant role in tiger conservation. But the reserve also gets immense pressure of cattle grazing (nearly 20,000 livestock enter SWR daily) from nearby village which is affecting the potential of reserve as tiger habitat. Most of the cattle are unproductive. In many cases local also don't want to keep these unproductive cattle but nobody would buy it. In Nepal cow is regarded as holy animal and killing is not allowed. With no option, they free their animals which ultimately goes into Wildlife Reserve. The cattle population is increasing as unwanted breeding continues during free grazing. In this scenario how could we reduce cattle grazing pressure in SWR? Is there any successful examples from others protected areas?

The government of Mauritius has decided to have a culling of our endemic fruit bat Pteropus niger based on the ground that the population is exploding and that they are acting as a pest, devastating fruit trees. This decision goes against all scientific studies carried out in Mauritius. The culling has already started and they have killed thousands of bats so far. Despite online petitions sent to the government, the decision was not re-considered.
Does anyone know a strategy that might help protect this important species?
The SADs package in R enables fitting species abundance distributions through maximum likelihood models, which is intuitively attractive. However, it seems like the fortran program RAD written by Werner Ulrich enables testing of a greater number of models. Should I use RAD simply because it allows fitting a greater number of models?

Tiger conservation efforts in the last decade only. Which are some of the more reliable sites on the web to get the required info from about Tiger conservation efforts in India?
I plan on using fecal samples to identify individuals within the study area. Within each grid cell I was planning on rather opportunistically hiking in good habitat, along animal paths, etc. As long as the effort is even across grid cells I am hoping that capture/recapture models will be effective? Concerning grid size, I know that probability of recapture is important, so is basing the cell size on the species' typical home range size appropriate? Thanks.
Edit/Update: Additional Info -
I am planning on conducting this research on giant pandas on a pretty small scale (focusing on the borders of Wolong Nature Reserve, perhaps with a 3km buffer on either side). Other research (telemetry studies) has resulted in an average home range size of about 7 square km in this area, using minimum convex polygon (MCP) methods. There is also pretty high spatial overlap in this species. So far I have been considering grid cells of 2.25 square km to ensure effective coverage (the terrain is extremely difficult), which would also result in a grid 2 cells deep on each side of the reserve, keeping with the 3km buffer.
On the other hand, perhaps this increases the chances of unneeded recaptures and the cell size could be increased to around 7 square km? This would also save greatly on time, which is a consideration. I am not sure which is more effective and what the trade-offs are when considering modelling/statistical analysis of the data later.
I'm planning an undergraduate student field project with mark recapture on wild mice and voles, and thinking about marking methods. As individuals only need to be marked for a week I don't want to use tags. I know fur clipping is often used, but what about temporary marks with hair dye or food dye? As this is for a student project with minimal previous experience handling small mammals I'm a bit cautious about using clipping. If you have used food dye / hair dye or know of something published which did, which brand was used (or a link to the reference)?
