Climate change may be a major threat to biodiversity in the next 100 years. Although there has been important work on mechanisms of decline in some species, it generally remains unclear which changes in climate actually cause extinctions, and how many species will likely be lost. Here, we identify the specific changes in climate that are associated with the widespread local extinctions that have already occurred. We then use this information to predict the extent of future biodiversity loss and to identify which processes may forestall extinction. We used data from surveys of 538 plant and animal species over time, 44% of which have already had local extinctions at one or more sites. We found that locations with local extinctions had larger and faster changes in hottest yearly temperatures than those without. Surprisingly, sites with local extinctions had significantly smaller changes in mean annual temperatures, despite the widespread use of mean annual temperatures as proxies for overall climate change. Based on their past rates of dispersal, we estimate that 57–70% of these 538 species will not disperse quickly enough to avoid extinction. However, we show that niche shifts appear to be far more important for avoiding extinction than dispersal, although most studies focus only on dispersal. Specifically, considering both dispersal and niche shifts, we project that only 16–30% of these 538 species may go extinct by 2070. Overall, our results help identify the specific climatic changes that cause extinction and the processes that may help species to survive.

AbstractThe breadth of a species’ climatic niche is an important ecological trait that allows adaptation to climate change, but human activities drive niche erosion. Life-history traits, such as dispersal ability and reproductive speed, instead allow species to cope with climate change. But how do these characteristics act in combination with human pressure to determine niche change? Here we investigate the patterns and drivers of change in the realised climatic niche of 589 terrestrial mammal species. Our goal is to disentangle the impacts of humans, climate change, and life history. We calibrated the past and present climatic niches of each species by considering past climatic conditions (Mid Holocene) within their pre-human impact distributions, and current climatic conditions within the current distributions. Depending on the relationship between past and current niche, we defined four categories of change: “shrink”, “shift”, “stable”, and “expand”. We found over half of the species in our sample have undergone niche shrink, while only 15-18% of species retained a stable niche. After controlling for biogeography, climatic factors were the strongest correlates of species niche change, followed by anthropogenic pressure and species’ life history. Factors that increased the probability of niche shrink include: overall climatic instability in the area (both intermediate or high), large body mass, long gestation time, highly carnivorous or herbivorous diets, historical land-use change, and current human population density. We identified the conditions under which species are less likely to maintain their niche breadth, potentially losing adaptation capacity under climate change. Species with these characteristics require interventions that facilitate natural dispersal or assisted colonisation, to survive to rapidly changing climates.

Migration Potential

Anticipating the next generation of forests requires understanding of recruitment responses to habitat change. Tree distribution and abundance depend not only on climate, but also on habitat variables, such as soils and drainage, and on competition beneath a shaded canopy. Recent analyses show that North American tree species are migrating in response to climate change, which is exposing each population to novel climate-habitat interactions (CHI). Because CHI have not been estimated for either adult trees or regeneration (recruits per year per adult basal area), we cannot evaluate migration potential into the future. Using the Masting Inference and Forecasting (MASTIF) network of tree fecundity and new continent-wide observations of tree recruitment, we quantify impacts for redistribution across life stages from adults to fecundity to recruitment. We jointly modeled response of adult abundance and recruitment rate to climate/habitat conditions, combined with fecundity sensitivity, to evaluate if shifting CHI explain community reorganization. To compare climate effects with tree fecundity, which is estimated from trees and thus is "conditional" on tree presence, we demonstrate how to quantify this conditional status for regeneration. We found that fecundity was regulated by temperature to a greater degree than other stages, yet exhibited limited responses to moisture deficit. Recruitment rate expressed strong sensitivities to CHI, more like adults than fecundity, but still with substantial differences. Communities reorganized from adults to fecundity, but there was a re-coalescence of groups as seedling recruitment partially reverted to community structure similar to that of adults. Results provide the first estimates of continent-wide community sensitivity and their implications for reorganization across three life-history stages under climate change.
