... The researchers set out to determine which of two competing hypotheses for the origin of chytridiomycosis was more plausible. If the fungus was recently introduced to an area, the researchers would expect to find a single genotype that had spread by clonal reproduction. If, however, the fungus is endemic to a...Satellite tracking will help answer questions about penguin travels

...unlight that reaches the forest floor. Some of the competing plants die because they can't get enough light.
