英文摘要Biologists have considered both winter coldness and temperature seasonality as major determinants of the northern limits of plants and animals in the Northern Hemisphere, which in turn drive the well-known latitudinal diversity gradient. However, few studies have tested which of the two climate variables is the primary determinant. In this study, we assess whether winter coldness or temperature seasonality is more strongly associated with the northern latitudinal limits of tree species and with tree species richness in North America. Tree species were recorded in each of 1198 quadrats of 110 km x 110 km in North America. We used correlation and regression analyses to assess the relationship of the latitude of the northern boundary of each species, and of species richness per quadrat, with winter coldness and temperature seasonality. Species richness was analyzed within 38 longitudinal, i.e., north-south, bands (each being >1100 km long and 110 km wide). The latitudes of the northern range limits of tree species were three times better correlated with minimum temperatures at those latitudes than with temperature seasonality. On average, minimum temperature and temperature seasonality together explained 81.5% of the variation in the northern range limits of the tree species examined, and minimum temperature uniquely explained six-fold (33.7% versus 5.8%) more of this variation than did temperature seasonality. Correlations of tree species richness with minimum temperatures were stronger than correlations with temperature seasonality for most of the longitudinal bands analyzed. Compared to temperature seasonality, winter coldness is more strongly associated with species distributions at high latitudes, and is likely a more important driver of the latitudinal diversity gradient.
