Longevity can buffer plant and animal populations against changing climatic variability.
Both means and year-to-year variances of climate variables such as temperature and precipitation are predicted to change. However, the potential impact of changing climatic variability on the fate of populations has been largely unexamined. We analyzed multiyear demographic data for 36 plant and animal species with a broad range of life histories and types of environment to ask how sensitive th...
متن کاملCan Individual and Social Patterns of Resource Use Buffer Animal Populations against Resource Decline?
Species in many ecosystems are facing declines of key resources. If we are to understand and predict the effects of resource loss on natural populations, we need to understand whether and how the way animals use resources changes under resource decline. We investigated how the abundance of arboreal marsupials varies in response to a critical resource, hollow-bearing trees. Principally, we asked...
متن کاملEcological and evolutionary impacts of changing climatic variability.
While average temperature is likely to increase in most locations on Earth, many places will simultaneously experience higher variability in temperature, precipitation, and other climate variables. Although ecologists and evolutionary biologists widely recognize the potential impacts of changes in average climatic conditions, relatively little attention has been paid to the potential impacts of...
متن کاملModelling animal populations in changing landscapes
Models of Mobile Animal Populations (MAP models) simulate long-term land use changes, population trends and patterns of biological diversity on landscapcs of lo3-lo5 ha. MAP models can incorporate information about past land-use pattcrns and management practices and can project future pattcrns based on management plans. We illustrate this approach with an cxamplc of how implerncntation of a US....
متن کاملRates of change in climatic niches in plant and animal populations are much slower than projected climate change.
Climate change may soon threaten much of global biodiversity. A critical question is: can species undergo niche shifts of sufficient speed and magnitude to persist within their current geographic ranges? Here, we analyse niche shifts among populations within 56 plant and animal species using time-calibrated trees from phylogeographic studies. Across 266 phylogeographic groups analysed, rates of...
