When a dam’s reservoir is flooded, organic matter is decomposed into mercury which becomes methylmercury. It can be harmful to ecosystems and humans. I was wondering if there could be any way to prevent mercury from being produced or to deal with it if it when a new dam is built.

Hi, On land, the nutrient cycle is closed by decomposer microorganisms (fungi, bacteria). Which organisms have the equivalent role in the sea? Thank you for your time. Cheers, ORF

This is for an alternate Earth that I've been building and rebuilding for years. Sometime between the Paleocene and Eocene epochs, there was a mysterious, sudden, dramatic rise in global temperature. This moment in time was known as the "Paleocene-Eocene Thermal Maximum", shortened into...

Hi I'm Andy, I'm a post-doctoral scholar at UCLA studying Ecology. I'm hoping that ecology can achieve some of the mathematical and theoretical rigor of physics one day.

How are they different? Decomposers - They convert complex molecules into simpler ones. Digestion (by heterotrophs) at any level does it, so why decomposers, another term then? Detrivores - They consume (engulf) dead1 and decaying (means already broken down? well what is that then?2) matter...

Surely this is a huge, huge find, is it not?? A living ecology, isolated for over 5 million years? http://ecowatch.com/2016/05/24/movile-cave-romania/ Scientists Uncover Array of Strange Animals in Cave That Has Been Sealed Off for 5.5 Million Years

Some small birds spiecies cooperate during the winter when searching for food. What are the pros and cons with this behavior? My solution: Cons: They have to share the food, it can be some rivalry => leads to fights. Pros: Easier to find food, when more searching, in the winter it might be...

Hi, I'm seeking information on a branch of mathematics. A few years back one of the education channels had a documentary in which scientists/mathematicians in Costa Rica were able to predetermine how a jungle was laid out by analyzing how the branches of an individual tree were laid out. Anyone...

Does anyone here consider ecology a hard science?

I want to work in ecology and I think it has potential to be a harder science. I like hard sciences and I think sometimes ecology has the image of being a soft science. Does anyone know of the progress being made in ecology? Give me some advice perhaps? Thanks.

As an aspirant scientist, physicist to be more precise, I believe it would be "normal" to be an ecologist. In fact I've always taken care of the Earth in my life since I've been taught to be respectful toward it. This means don't throw objects in nature, don't kill amphibians, don't burn...

So I would like to do an ecology course somewhen during my undergrad, but the requisites for a General Ecology are just too big: -1 year in Zoology and Botany -1 year in General Biology (in order to get the Zoology and Botany) I have studied myself the Smith ecology book and don't find...

Homework Statement A flock of 10 Kolea birds going back to its mating grounds in Alaska from Hawaii gets blown off course and lands on a small island in the Aleutian (with no other Kolea birds) that is 25 km2 and has tundra habitat. The birds are known to have an intrinsic growth rate of 1.8...

I am preparing my examination on next week. I face a challenge question on the textbook but it does not provide any answers. Can someone help me? Two questions distribute 10 marks for each. How can I answer point by point to get all the marks in this questions. Many thanks! Consider this...

Hello I'm interested in pursuing ecological studies. I'm trying to find out as much as I can about the nature of ecological science. I have seen some books in my school library about mathematical ecology and my ecology professor has said that ecology is pretty quantitative. I have hopes that...

Hi, I just found this great forum and I am hoping to get some advice. I am starting an ecology degree with the hope of, one day, getting into grad school. I don't know yet what type of research I would like to do but I want to keep the door to theoretical work open. As my math background is...

Hi, I have a square grid that represents a landscape, each grid cell is forested or non-forested. I am calculating 2 different forest fragmentation metrics. Because there is a finite number of combinations of forest and nonforest cells, there is a finite number of possible values for each...

Pop. Ecology r and K strategists please help Does anyone know what the "K" of k-strategist stands for? I know the "r" in r-strategist stands for rapid but cannot find what the k stands for. Thanks!
