The impact of climatic change on wild animals and plants: a meta-analysis

摘要: Over the last 100 years, global average temperature has increased approximately 0.6° C. Using information from literature, we examine extent to which animals and plants are already exhibiting a discernible change consistent with changing temperatures predicted by our understanding of species’ physiological constraints. The types changes include poleward altitudinal range expansions, movement abundance patterns, shifts in morphometrics, genetics, behavior, timing events such as animal breeding or plant blooming dates. We examined over 2500 articles find those that met following conditions -they span at least 10 years meet two criteria (all association had be statistically significant): 1) A trait one species (e.g., shifting boundary) shows time. 2) That is correlated local temperature. 3) Local time period study. 45 studies meeting these 1250 species. Metaanalyses provide way combine results different and, when taken together, reveal an underlying shift, “fingerprint,” among various taxa locations virtually around globe. Hence, balance evidence obtained suggests significant impact climatic warming form long-term, large-scale alteration populations.
