What does species richness tell us about functional trait diversity? Predictions and evidence for responses of species and functional trait diversity to land‐use change
Global Ecology and Biogeography - Tập 19 Số 4 - Trang 423-431 - 2010
Margaret M. Mayfield, Stephen P. Bonser, John W. Morgan, Isabelle Aubin, Sean McNamara, Peter A. Vesk
ABSTRACTIn the conservation literature on land‐use change, it is often assumed that land‐use intensification drives species loss, driving a loss of functional trait diversity and ecosystem function. Modern research, however, does not support this cascade of loss for all natural systems. In this paper we explore the errors in this assumption and present a conceptual...... hiện toàn bộ
Functional relationships beyond species richness patterns: trait matching in plant–bird mutualisms across scales
Global Ecology and Biogeography - Tập 23 Số 10 - Trang 1085-1093 - 2014
D. Matthias Dehling, Till Töpfer, H. Martin Schaefer, Pedro Jordano, Katrin Böhning‐Gaese, Matthias Schleuning
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
Heather Bird Jackson, Lenore Fahrig
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. Sc...... hiện toàn bộ
Partitioning the turnover and nestedness components of beta diversity
Global 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
The relationship between species replacement, dissimilarity derived from nestedness, and nestedness
Global Ecology and Biogeography - Tập 21 Số 12 - Trang 1223-1232 - 2012
Andrés Baselga
ABSTRACTAim  Beta diversity can be partitioned into two components: dissimilarity due to species replacement and dissimilarity due to nestedness ( hiện toàn bộ
Decomposing functional β-diversity reveals that low functional β-diversity is driven by low functional turnover in European fish assemblages
Global Ecology and Biogeography - Tập 22 Số 6 - Trang 671-681 - 2013

Refugia: identifying and understanding safe havens for biodiversity under climate change
Global Ecology and Biogeography - Tập 21 Số 4 - Trang 393-404 - 2012
Gunnar Keppel, Kimberly P. Van Niel, Grant Wardell‐Johnson, Colin J. Yates, Margaret Byrne, Ladislav Mucina, A.G.T. Schut, Stephen D. Hopper, Steven E. Franklin
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
Above‐ground biomass estimation in closed canopy Neotropical forests using lidar remote sensing: factors affecting the generality of relationships
Global Ecology and Biogeography - Tập 12 Số 2 - Trang 147-159 - 2003
Jason Drake, Robert G. Knox, R. Dubayah, David B. Clark, Richard Condit, J. B. Blair, M. A. Hofton
ABSTRACTAim Previous studies have developed strong, site‐specific relationships between canopy metrics from lidar (light detecting and ranging) remote sensing data and forest structural characteristics such as above‐ground biomass (AGBM), but the generality of these relationships is unknown. In this study, we examine the generality of relatio...... hiện toàn bộ
Land use and climatic factors structure regional patterns in soil microbial communities
Global 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 regimes
Global Ecology and Biogeography - Tập 23 Số 7 - Trang 821-824 - 2014
David M. J. S. Bowman, Brett P. Murphy, Grant J. Williamson, Mark A. Cochrane
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
