amphibian populations are decliningrapidly worldwide. the fungus Batrachochytrium dendrobatidis (Bd) has contributedto this decline: this pathogen causes severeskin infections in many amphibian species,leading to massive die-offs. efforts to saveamphibians from Bd have met with limitedsuccess, and there is little evidence thatfrogs and other amphibians have acquiredresistance to Bd on their own.
Population Growth
R and K Selection
R and K selection are concepts in ecology used to describe traits in the fluctuation of a population or population dynamics. For example, they describe the life-association traits between parent and offspring, such as quantity or number of young ones born at a time, quality of parental care, the age to maturity, and reproductive effort.
