Does the biogeographic origin of species matter? Ecological effects of native and non‐native species and the use of origin to guide management (2016, background): “The impacts of non-native species on ecosystem function are potentially even greater at global and continental scales, a scale often too large for biodiversity-ecosystem function experiments, where beta and gamma diversity are declining (Sax & Gaines 2003).”
Niche‐based modelling as a tool for predicting the risk of alien plant invasions at a global scale (2005, background): “Economic globalization thus, is, also reducing the regional distinctiveness of the Earth’s biota ( Sax & Gaines, 2003 ).”
Functional identity is more important than diversity in influencing ecosystem processes in a temperate native grassland (2008, background): “Globally, anthropogenic species loss, species invasions and intensification of natural resource use are dramatically altering biotic communities (Sax & Gaines 2003).”
Is local biodiversity declining or not? A summary of the debate over analysis of species richness time trends (2018, background): “Sax and Gaines (2003) were among the ﬁ rst to show that rates of species introductions into large regions (e.g., islands, mainland ecosystems) sometimes equal or exceed rates of species extinctions.”
On defining and quantifying biotic homogenization (2006, background): “…activities have led to decreased global species diversity, the opposite pattern is often observed at regional and local scales where the establishment of exotic species frequently outweighs the loss of native species, so total species diversity increases over time (reviewed in Sax & Gaines, 2003).”
A conceptual framework for comparing species assemblages in native and exotic habitats (2005, background): “Recent work by Sax et al. (2002) and Sax and Gaines (2003) has stressed that species diversity may change as a consequence of exotic species invasions in different ways (increasing, decreasing or remaining unchanged), at different spatial scales (global, regional and local), for different taxonomic…”
Invasion Biology 1958-2005: The Pursuit of Science and Conservation (2004, background): “…to widespread species introductions, the common contention that species introductions lead to declines in regional and local biodiversity was challenged by several investigators (Rosenzweig 2001, Davis 2003, Sax and Gaines 2003), a point that had actually been made much earlier by Harper (1965).”
Biotic homogenization: a new research agenda for conservation biogeography (2006, background): “Although human activities have led to decreased global species diversity as a result of species extinctions, at regional and local scales the introduction of non-indigenous species has often outweighed the loss of natives such that species richness has increased over time (Sax & Gaines, 2003).”
Worldwide freshwater fish homogenization is driven by a few widespread non-native species (2016, background): “Indeed, in most regions the number of non-native species introduced exceeds the number of extirpations, which ultimately leads to an increase in local species richness (Sax and Gaines 2003; Cassey and Lockwood 2007; Cadotte et al. 2009).”
Incursion and excursion of Antarctic biota: past, present and future (2006, neutral): “…but at smaller (e.g. individual island) scales there are Biotic transport in and out of Antarctica © 2006 The Authors Global Ecology and Biogeography , 15 , 121–142, Journal compilation © 2006 Blackwell Publishing Ltd 123 often increases in richness (Sax et al ., 2002; Sax & Gaines, 2003).”
The biogeography of naturalization in alien plants (2006, background): “The net effect on species diversity therefore depends on the spatial and temporal scale under consideration, and on the balance between naturalization and extinction (Sax et al., 2002; Sax & Gaines, 2003).”
Integrating the Study of Non-native Plant Invasions across Spatial Scales (2006, background): “For plant invasions, changes in species richness can be summarized across scales as increases in local diversity due to the arrival of new species, and decreases at the global scale by homogenization of the biota (Sax and Gaines 2003).”
Tree species richness and density affect parasitoid diversity in cacao agroforestry (2004, background): “The maintenance of natural forest canopy as shade trees in the cacao agroforestry system may have conserved, or even enhanced (see Sax & Gaines, 2003), the naturally occurring number of parasitoid families.”
