主 题：Atlantic Forest biogeography climatic niche latitudinal gradient snakes
摘 要：The climatic niche is a central concept for understanding species distribution,with current and past climate interpreted as strong drivers of present and historical-geographical *** aim is to understand whether Atlantic Forest snakes follow the general geographical pattern of increasing species climatic niche breadths with increasing *** also tested if there is a tradeoff between temperature and precipitation niche breadths of species in order to understand if species with larger breadths of one niche dimension have stronger dispersal constraints by the other due to narrower niche *** breadths were calculated by the subtraction of maximal and minimal values of temperature and precipitation across species *** implemented Phylogenetic Generalized Least Squares to measure the relationship between temperature and precipitation niche breadths and *** also tested phylogenetic signals by Lambda statistics to analyze the degree of phylogenetic niche conservatism to both niche *** niche breadths were not related to *** niche breadths decreased with increasing latitude and presented a high phylogenetic signal,that is,significant phylogenetic niche *** rejected the tradeoff hypotheses of temperature and precipitation niche *** results also indicate that precipitation should be an important ecological constraint affecting the geographical distribution of snake lineages across the South American Atlantic *** then provide a general view of how phylogenetic niche conservatism could impact the patterns of latitudinal variation of climatic niches across this biodiversity hotspot.
