What is the smallest viable reproducing population, such as in a human population. By viable I mean a population which keeps genetic defects low (enough). A very strongly related question: what is ...
Colony Collapse Disorder is a well studied phenomenon relating to the decline of bee populations - has this disorder, or its equivalent, been observed in other colony-based species?
Natural selection is a central tenet of evolution. However, most biologists seem determined to prevent the extinction of the species that have been selected against. Why is this? Preservation of ...
I have a biology assignment and we have to explain various methods and strategies for conservation, two of which are: Biological control Introduced Species What is the difference between ...
In some animals (like dogs) size seems like it's controlled mostly by just a few genes (IGF1, and the genes that repress it). I'm curious: (1) Does other miniaturization takes a similar route (for ...
Let's think about the slash and burn method and its effects on the ecosystem. Cutting down trees that rise all the way up to the canopy would expose the plants at ground level to more light, so would ...
I am not a biologist but I just wonder if all species are interdependent. I mean if the tiger becomes extinct does it affect the ecosystem? If the mosquito or mouse become extinct does it affect the ...
