Effects of global climate change on geographic distributions of Mexican Cracidae

Large-Herbivore Distribution and Abundance: Intra- And Interspecific Niche Variation in the Tropics

“…complete distributions and at smaller spatial scales Holt 2003, Murphy andLovett-Doust 2007). There is an increasing demand for this detailed ecological information, in view of its importance in guiding conservation measures in the face of global climate change (see Peterson et al 2001, Hughes 2003, Rondinini et al 2005, Sagarin et al 2006. Our results indicate clear interspecific differences in the factors affecting the abundance of three sympatric large herbivores across the tropical savannas of northern Australia.…”

“…Although considerable effort has been devoted to identifying factors that influence species abundance, Sagarin et al (2006) stress that, despite the many advances in experimental ecology over recent decades, we are severely ''observationlimited'' with regard to detailed information on abundance across species' distributions, particularly at larger spatial scales. This information is urgently required to allow us to adequately address large-scale environmental changes, such as global climate change (Peterson et al 2001, Hughes 2003, Rondinini et al 2005.…”

Correlates of vulnerability to climate-induced distribution changes in European avifauna: habitat, migration and endemism

“…Prioritizing the conservation of species with small ranges is long-standing practice, but is even more important in the light of predicted climate change. For range-restricted species, designations of PAs within the predicted distribution, and the creation of stepping stones and corridors to facilitate dispersal, are critical, particularly for poor dispersers (Peterson et al 2001). Endemic and near-endemic species typically have smaller reductions in range size compared to cosmopolitan species, but have lower overlap values.…”

Climate Change and Biodiversity: Some Considerations in Forecasting Shifts in Species' Potential Distributions

“…This approach uses georeferenced primary occurrence data for species, in combination with digital maps representing environmental parameters, to build models of the ecological requirements of species-the set of conditions suitable and necessary for long-term survival of populations of the species without immigrational input. Then, such conditions are located on landscapes, and maps created to indicate the distributional potential of the species (Pearson and Dawson 2003;Peterson et al 2001;Thuiller 2003). With this approach, distributional shifts caused by climatic change, in both the past and the future, can be estimated based on the fact that the niche model is characterized in ecological space-conditions with which a species is associated at present can be sought on modeled future or past climate scenarios ( Fig.…”

“…Previous studies have shown that dispersal patterns are species-specific, and also depend on the geography of the area, which can make predictions difficult (Clark et al 2003; et al 1998b;Dullinger et al 2004;Post and Forchhammer 2002;Travis and Dytham 2002). As a result, some authors do not attempt to present definite future distributional predictions, but rather a set of possible scenarios based on different dispersal assumptions, ranging from no dispersal to universal dispersal (Peterson et al 2001). In this way, one can at least bracket possible effects of climate change on species' distributions.…”
