Partitioning the turnover and nestedness components of beta diversity 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 assessment of beta diversity, disentangling
the contributi... hiện toàn bộ
Landscape modification and habitat fragmentation: a synthesis Tập 16 Số 3 - Trang 265-280 - 2007
Joern Fischer, David B. Lindenmayer
ABSTRACTLandscape modification and habitat fragmentation are key drivers of
global species loss. Their effects may be understood by focusing on: (1)
individual species and the processes threatening them, and (2) human‐perceived
landscape patterns and their correlation with species and assemblages.
Individual species may decline as a result of interacting exogenous and
endogenous threats, including... hiện toàn bộ
Elevation gradients of species‐density: historical and prospective views Tập 10 Số 1 - Trang 3-13 - 2001
Mark V. Lomolino
AbstractStudies of elevation clines in diversity and composition of ecological
communities date back to the origins of biogeography. A modern resurgence of
interests in these elevational clines is likely to contribute important insights
for developing a more general theory of species diversity. In order to gain a
more comprehensive understanding of geographical clines in diversity, the
research pr... hiện toàn bộ
The importance of biotic interactions for modelling species distributions under climate change Tập 16 Số 6 - Trang 743-753 - 2007
Miguel B. Araújo, Miska Luoto
ABSTRACTAim There is a debate as to whether biotic interactions exert a
dominant role in governing species distributions at macroecological scales. The
prevailing idea is that climate is the key limiting factor; thus models that use
present‐day climate–species range relationships are expected to provide
reasonable means to quantify the impacts of climate change on species
distributions. However, ... hiện toàn bộ
Refugia: identifying and understanding safe havens for biodiversity under climate change 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 changing environmental conditions. However, the
study and dis... hiện toàn bộ
Interpreting the replacement and richness difference components of beta diversity Tập 23 Số 11 - Trang 1324-1334 - 2014
Pierre Legendre
AbstractAimThe variation in species composition among sites, or beta diversity,
can be decomposed into replacement and richness difference. A debate is ongoing
in the literature concerning the best ways of computing and interpreting these
indices. This paper first reviews the historical development of the formulae for
decomposing dissimilarities into replacement, richness difference and nestedness... hiện toàn bộ

Bio‐ORACLE: a global environmental dataset for marine species distribution modelling Tập 21 Số 2 - Trang 272-281 - 2012
L. Tyberghein, Heroen Verbruggen, Klaas Pauly, Charles Troupin, Frédéric Mineur, Olivier De Clerck
ABSTRACTAim The oceans harbour a great diversity of organisms whose
distribution and ecological preferences are often poorly understood. Species
distribution modelling (SDM) could improve our knowledge and inform marine
ecosystem management and conservation. Although marine environmental data are
available from various sources, there are currently no user‐friendly,
high‐resolution global datasets... hiện toàn bộ
Bio‐ORACLE v2.0: Extending marine data layers for bioclimatic modelling Tập 27 Số 3 - Trang 277-284 - 2018
Jorge Assis, L. Tyberghein, Samuel Bosch, Heroen Verbruggen, Ester Á. Serrão, Olivier De Clerck
AbstractMotivationThe availability of user‐friendly, high‐resolution global
environmental datasets is crucial for bioclimatic modelling. For terrestrial
environments, WorldClim has served this purpose since 2005, but equivalent
marine data only became available in 2012, with pioneer initiatives like
Bio‐ORACLE providing data layers for several ecologically relevant variables.
Currently, the availa... hiện toàn bộ
The relationship between species replacement, dissimilarity derived from nestedness, and nestedness 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
(Baselga, 2010, Global Ecology and Biogeography, 19, 134–143). Several
contributions have challenged this approach or proposed alternative frameworks.
Here, I review the concepts and methods used in these recent contributions, with
the aim of clarifying: ... hiện toàn bộ
