Aim Beta diversity can be partitioned into two components: dissimilarity due to species
replacement and dissimilarity due to nestedness (Baselga, 2010, Global Ecology and …

Earth's climate has experienced strong changes on timescales ranging from decades to
millions of years. As biodiversity has evolved under these circumstances, dependence on …

Freshwater fish represent one-fourth of the world's vertebrates and provide irreplaceable
goods and services but are increasingly affected by human activities. A new index …

Appropriation of fresh water to meet human needs is growing, and competition among users
will intensify in a warmer and more crowded world. This essay explains why freshwater …

Aim The 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 …

Animals and plants worldwide are structured in global biogeographic regions, which were
shaped by major geologic forces during Earth history. Recently, humans have changed the …

Abundance‐based assemblage dissimilarity can be partitioned into components accounting
for (i) balanced variation in abundance, whereby the individuals of some species in one site …

Aim One of the main gaps in the assessment of biodiversity is the lack of a unified framework
for measuring its taxonomic and functional facets and for unveiling the underlying patterns …

Site‐to‐site variation in species composition (β‐diversity) generally increases from low‐to
high‐diversity regions. Although biogeographical differences in community assembly …

Dissimilarity measures can be formulated using matching components that can be defined
as the intersection in terms of species composition of both sets (a) and the relative …
