Functional relationships beyond species richness patterns: trait matching in plant–bird mutualisms across scalesGlobal Ecology and Biogeography - Tập 23 Số 10 - Trang 1085-1093 - 2014

AbstractAimFunctional relationships between species groups on macroecological scales have often been inferred from comparisons of species numbers across space. On large spatial scales, however, it is difficult to assess whether correlations of species numbers represent actual functional relationships. Here, we investigated the fun...... hiện toàn bộ
Are ecologists conducting research at the optimal scale?Global Ecology and Biogeography - Tập 24 Số 1 - Trang 52-63 - 2015

AbstractAimThe spatial extent (scale) at which landscape attributes are measured has a strong impact on inferred species–landscape relationships. Consequently, researchers commonly measure landscape variables at multiple scales to select one scale (the ‘scale of effect’) that yields the strongest species–landscape relationship.

Partitioning the turnover and nestedness components of beta diversityGlobal Ecology and Biogeography - Tập 19 Số 1 - Trang 134-143 - 2010
Andrés Baselga
ABSTRACTAim Beta diversity (variation of the species composition of assemblages) may reflect two different phenomena, spatial species turnover and nestedness of assemblages, which result from two antithetic processes, namely species replacement and species loss, respectively. The aim of this paper is to provide a unified framework for the as...... hiện toàn bộ
Refugia: identifying and understanding safe havens for biodiversity under climate changeGlobal Ecology and Biogeography - Tập 21 Số 4 - Trang 393-404 - 2012

ABSTRACTAim Identifying and protecting refugia is a priority for conservation under projected anthropogenic climate change, because of their demonstrated ability to facilitate the survival of biota under adverse conditions. Refugia are habitats that components of biodiversity retreat to, persist in and can potentially expand from under chang...... hiện toàn bộ
Land use and climatic factors structure regional patterns in soil microbial communitiesGlobal Ecology and Biogeography - Tập 19 Số 1 - Trang 27-39 - 2010
Rebecca E. Drenovsky, Kerri L. Steenwerth, Louise E. Jackson, Kate M. Scow
ABSTRACTAim Although patterns are emerging for macroorganisms, we have limited understanding of the factors determining soil microbial community composition and productivity at large spatial extents. The overall objective of this study was to discern the drivers of microbial community composition at the extent of biogeographical provinces an...... hiện toàn bộ
Pyrogeographic models, feedbacks and the future of global fire regimesGlobal Ecology and Biogeography - Tập 23 Số 7 - Trang 821-824 - 2014

AbstractConceptual and phenomenological macroecological models of current global fire activity have demonstrated the overwhelming control exerted by primary productivity. Fire activity is very high in savanna regions with intermediate primary productivity, and very low in both densely forested regions with high productivity and arid/cold regions with low productivi...... hiện toàn bộ
