I have some environmental covariates derived from the digital elevation model (slope, gradient, channel network distance, etc.) in raster format.
I want to identify areas of similarity between the covariates and somehow identify the smallest possible size area (or areas) to serve as a reference area.
  1. Soil data points will be collected to create predictive models in this reference area.
  2. The predictive models developed in the reference areas should fit when extrapolated to regions outside the reference area.
  3. Therefore, the covariates will cover this external area.
Relevant answer
Answer
Erupting volcanoes cause sudden, drastic change in an area, forcing organisms to evolve rapidly to adapt to the new environment. Change in an organism's environment forces the organism to adapt to fit the new environment, eventually causing it to evolve into a new species. They eventually become different species. So that changes in environmental conditions can affect the survival of individual organisms or an entire species. Short-term environmental changes, like droughts, floods, and fires do not give populations time to adapt to the change and force them to move or become extinct. However, short and long term environmental changes Quiz - Quizizz. What is an example of how organisms respond to short term changes in the environment? Animals tend to eat a lot more before the change occurs to have stored energy. Animals will go extinct or die due to the short term change. Therefore, in evolutionary theory, adaptation is the biological mechanism by which organisms adjust to new environments or to changes in their current environment. The idea of natural selection is that traits that can be passed down allow organisms to adapt to the environment better than other organisms of the same species.

Everyone knows, the fast changing climatic condition with altered physical factors due to various anthropologic activities. Humans are unable to handle the issue of climate change due to growing needs and population. So, how nature will resolve the issue of climate change without human interference?
Relevant answer
Answer
If greenhouse gas emissions continue to grow in the coming years, the global warming process will accelerate and become an irreversible process in the next several dozen years. Therefore, climate change can be so great that nature will not solve the problem either. Forest fires, droughts, and weather anomalies will intensify. The biodiversity of natural ecosystems will quickly decline, it will be impoverished in terms of the composition of flora, fauna, fungi and microorganisms, and in terms of the genetic composition of the planet Earth's biosphere. Nature will not stop these unfavorable processes of climate change, but will be subject to these processes. So nature, preserving the biodiversity of natural ecosystems, can be helped primarily by people who, by implementing the principles of sustainable development, social environmental (ecological) responsibility, pro-ecological reforms of implementing eco-innovations in economic processes, etc., and other pro-ecological transformation of the traditional brown economy into a sustainable green economy / circular economy can save the biosphere of planet Earth from the climate crisis. If it's not too late, of course. But no matter how much time is left for the implementation of this pro-ecological action plan, it must be implemented urgently.

Infectious ecology is a new line of research. In a clear way, it was formulated in 2017. In 2018, some works were carried out that showed the significance and real novelty of this scientific approach. On its basis, new theoretical interpretations of a whole range of infectious diseases can be given.
The case of KDD is not unique. There are a considerable number of infectious novelties that are difficult to understand in the dominant scientific terms. An example would be ebola. In the infectious ecology, an attempt is made to re-state the problem and to find a new solution for the KDD.
The basic idea is that we are dealing with another manifestation of the discrete activation of the pathogenic properties of microorganisms. As in many other cases, the cause is a change in soil geochemistry. That it is a pretext for the manifestation of the pathogenic properties of Phytophthora agathidicida. This is usually associated with agriculture and anthropogenic changes.

Dear Dimitry,
You may be interested in Chaboussou, Sante des Plantes, une revolutions agronomique, (1985) translated as Healthy Crops, A New agricultural Revolution. (2004). It describes how agrochemicals cause the proliferation of pests and diseases. We are starting a new project to bring this up to date and confirm/or deny the ideas. I would be happy to cooperate.

Christian Nold (2009) in his book of essay Emotional Cartography aims to 
explore the political, social and cultural implications of visualising intimate biometric data and emotional experiences using technology.
In my research (http://www.pocitovemapy.cz/index-en.html) I work with term emotional mapping, but I have been told by some other researchers, readers and reviewers, that emotional mapping is not the correct term, as emotions is not what is being mapped.
I usually ask people to identify places on the map, where they feel afraid (mapping of safety), where they "like it" (spatial preferences), but also places where they spend free time, or places where it is dirty (environment pollution, etc.).
Which term, would you suggest for this kind of subjective mapping - would it be emotional maps or maps of perceptions? And what do you think is the main difference?
Thank you!
Relevant answer
Answer
Kind Jiri,
may be "Sentimapping" a more suitable neologism for Your theoretical and practical purposes ? At least, just to respect the difference between "emotion" and "sentiment", given that in a map, usually, we try to represent something that is closer to a sentiment towards a place, an object, ecc., much more than to a unique emotion...
Just an idea.

Answer
Google Maps has the most reliable and accurate database for geocoding (assigning lat lon coordinates to addresses), here are instructions for their API: https://developers.google.com/maps/documentation/geocoding/intro
If you're familiar with QGIS (https://www.qgis.org/en/site/forusers/download.html), you can install plugin called MMQGIS and easily geocode list of locations in CSV format, here are instructions how to download and use the plugin: https://www.lib.uwo.ca/madgic/projects/gis/Geocoding%20Using%20QGIS.pdf
You should prefer using Google as a source rather than OpenStreetMap (OSM).

From January 2014 to December 2016, I conducted monthly field trips in three different areas of Dhaka city, Bangladesh to investigate how butterflies survive in an inner-city habitat. I have found that the species richness (I did not count the species abundance) is declining with time.
Presently, I have:
* monthly species-specific data of three continuous years (36 continuous months) of the three different areas
* Four environmental variables (temperature, rainfall, humidity and sunshine hours)
* Pollution level
* IUCN Red List status
* Land-use analysis of these three different areas
Now, I am really confused considering the proper way to link these pieces of information! Could anyone of you please share some ideas?

The conditions in the different geographic areas are clearly different, this causes that the same taxa undergo transformations that can be both morphological and physiological, this is used in studies related to the adaptability that is able to develop a certain organism before different conditions, which Tells us its ability to survive under unequal conditions, and in case of possessing any component that can be exploited, such as pigments, it is possible to extrapolate the conditions of the environment where it produces to be exploited later.

From January 2014 to June 2016, through the continuous field trips, I have listed all those butterflies which were spotted. Now, I have analysed the land area management of Dhaka city which contains over 17 million inhabitants. The total species number is 136 and a good number of them are Endangered and Vulnerable according to regional IUCN Red List 2016. How can I synchronize these data? Is it possible to make a conservation management plan with the help of this research? Please help..
Relevant answer
Answer
Field data are always useful to draw CM plans. In fact, it often happens that CM plans are incomplete because information that actually existed could was not incorporated to them. The papers below show three such cases (for various taxa) where Management Plans, field data, and literature or IUCN data all had occurrence data that were absent from the other sources, resulting in partial knowledge and therefore less-than-optimal plans. Data synchronization was accomplished through database mining and GIS analytics. Methods are explained in the papers.
The difference between the amount of knowledge in a plan, and the amount of existing knowledge that could have been put in a plan, should become a priority especially when endangered species are present. The fourth reference (link) below is a draft for a document dealing with this type of gap analysis.

Hi Nathan,
I think what you want to do may require a very high resolution earth observation dataset, something between 1 to 5m resolution. Having said that, you should think about carrying out an Object-Based Image Analysis. First, go through the works of Prof. Thomas Blaschke, he is an expert in this area. I learnt some of the techniques from his works. On the other hand, you may wish to go through the following papers at the links below:

I know this is question highly depended on geographic location, but is there an average deposition of NH4 from the atmosphere into a body of freshwater? I'm specifically looking for a reference that gives the amount of NH4 deposited into a litre (or m2- surface area) of water per year. I'm looking for references ideally from the UK. 
I'm specifically looking for references that report atmospheric deposition, independent of dust/rain/bird droppings etc. 
Any help or advice pointing me in the right direction will be very much appreciated.

Ammonia is NH3, which is a very light gas,whereas ammonium (NH4) is a basic radical. The gas being far lighter than air, & very sparingly soluble under high pressure, I find it surprising as to how the gas can dissolve in fresh waters from atmosphere under natural conditions.

Hello
I would like to know if any simple bioclimatic index has been proposed (as Humidex or Heat Index for mixing the effect of temperature and humidity) to include the deleterious effect of strong winds when T > 37°C or so. I know that some indices already include the cooling effect of strong winds (as net effective temperature) when T is low but I am rather interested by the warming effect of winds. I add that I am looking for a synthetic index (not as complex as UTCI for example).
Thank you in advance

Dear Vincent Moron
The most simple and enough  accurate Index you need was developped by Baruch Givoni "The Index of Thermal Stress" ITS  # 5.6 and #16.1,c (The building Bioclimatic Chart).
.See in his book "Man Climate and Architecture" Applied Science Publishers - London 1976 Reprinted 1901
Take into account that certainly you must consider that no "acceptable discomfort" will you found under the sun, but in the shade properly dressed. Then the formulation is much simple if direct solar radiation is not considered.
Then you need to evaluate which is the acceptable E/Emax value you need according to the sweat rate Inex of humidity. Certainly no Comfort will be found at 37 degC, But you can define the (also) acceptable low metabolic rate...

The great alluvial Plain of Catania (Piana di Catania) is situated in the East of the mediterranean island of Sicily. Basically two rivers flow there along the sides of the plain into the sea: Simeto and Gornalunga. The region is absolutely ideal for bronze age water engineers to build the usual bronze age water engineering. Yet, I cannot find any academic work on this.
