A demographic approach to understanding the effects of climate on population growth.

摘要: Amphibian life history traits are affected by temperature and precipitation. Yet, connecting these relationships to population growth, especially for multiple populations within a species, is lacking precludes our understanding of amphibian dynamics distributions. Therefore, we constructed integral projection models five along an elevational gradient determine how climate season affect growth terrestrial salamander Plethodon montanus the importance demographic vital rates under varying scenarios. We found that was typically higher at highest elevation compared lower elevations, whereas inactive conditions, represented late fall, winter early spring, produced greater variation in than active conditions (late summer, fall). Furthermore, survival were consistently more important, as measured elasticity, fecundity, large females had greatest elasticity all other body sizes. Our results suggest changing those would individuals, may have impact on growth. recommend future experimental studies focus better elucidate mechanisms which can survival.
