Population responses to observed climate variability across multiple organismal groups

A major challenge in ecology is to understand how populations are affected by increased climate variability. Here, we assessed the effects of observed variability on different organismal groups (amphibians, insects, mammals, herbaceous plants and reptiles) estimating extent which interannual variation annual population growth rates (CV?) absolute value long-term rate (|log ?|) were associated with short-term We used empirical data (? 20 consecutive years abundances) from 59 wild Northern Hemisphere, quantified variabilities climatic conditions (temperature precipitation active inactive seasons) calculated over four- eight-year sliding time windows. a positive relationship between temperature season at shorter timescale only. Moreover, |log ?| was positively both timescales. Otherwise, direction relationships dynamics (if any) depended largely group question. Both CV? correlated negatively species' lifespan, indicating general differences short-lived long-lived species that not related Our results suggest although temporal magnitude partially variability, demographic responses fluctuations might still be population-specific rather than specific given groups, driven other factors
