Ecology 6th Edition by Charles Krebs

تمرين 1

Amphibian populations have been declining in many parts of the world during the past 20 years (Stuart et al. 2003). Discuss the hypotheses proposed to explain these declines and suggest a research plan to rescue these populations. Davidson and Knapp (2007) discuss multiple causes for these declines, and Whitfield et al. (2007) provide a global overview of the problem.
