Loss of habitat and connectivity erodes species diversity, ecosystem functioning, and stability in metacommunity networks (2017, background): “In addition, biodiversity loss may impact the stability of ecosystem functioning as communities with low diversity are less resistant to environmental fluctuations, (Isbell et al. 2011, 2015), leading to more variable population and aggregate biomass (Gonzalez and Loreau 2009, Hector et al. 2010).”
Biodiversity and Ecosystem Functioning (2014, background): “Experimental fragmentation, another form of nonrandom community change, reduced the diversity and community biomass of arthropods in microcosm fragments (Gonzalez & Chaneton 2002).”
Contrasts between habitat generalists and specialists: an empirical extension to the basic metacommunity framework. (2009, background): “Other metacommunity studies have examined the role of connectivity and dispersal between patches (Gonzalez et al. 1998, Forbes and Chase 2002, Gonzalez and Chaneton 2002), the effects of dispersal and predation at local and metacommunity scales (Kneitel and Miller 2003, Cadotte 2006), or used…”
Traits explain community disassembly and trophic contraction following experimental environmental change (2012, background): “Immigration from adjacent high-quality (moist) areas may have boosted species richness and increased long-term survival of metapopulations (Gonzalez & Chaneton, 2002; Binzenhoefer et al., 2008), although no effect of the corridor treatment was observed for patterns of abundance.”
The metacommunity concept: a framework for multi-scale community ecology (2004, background): “One well-studied example of this first kind derives from experimental work using carpets of epilithic moss, containing a species-rich assemblage of microarthropods; experiments showed that altering landscape connectivity influenced several community properties, such as local and regional diversity a”
Confounding factors in the detection of species responses to habitat fragmentation (2005, background): “Although no direct estimates have yet been made for the half-life of invertebrate extinction debts, Gonzalez (2000) and Gonzalez & Chaneton (2002) found that the extinction debt of microarthropods in an experimentally fragmented moss microsystem was apparently paid in six to twelve months.”
Biodiversity-Ecosystem Function Research: Is It Relevant to Conservation? (2005, background): “…food webs brings us closer to connecting BDEF research and conservation concerns, but ultimately we need to consider the underlying causes of biodiversity change and their direct effects on ecosystem function (Gonzalez & Chaneton 2002, Schmid & Hector 2004, Srivastava 2002, Wardle 2002, Figure 1).”
Species richness and evenness respond in a different manner to propagule density in developing prairie microcosm communities (2007, unknown): “Alternatively, if rare species are more likely to go locally extinct (Duncan and Young 2000; Gonzalez and Chaneton 2002; Wilsey and Polley 2004), then evenness of the remaining species would increase slightly in concert with each decrease in richness due to local extinction.”
Small-scale habitat use and assemblage structure of ground-dwelling beetles in a Patagonian shrub steppe (2006, background): “A better knowledge of microhabitat use by arthropods may help to understand community assembly (Morin, 1999), as well as predicting biodiversity changes due to habitat loss (Gonzalez and Chaneton, 2002; Tews et al., 2004).”
Metacommunity diversity depends on connectivity and patch arrangement in heterogeneous habitat networks (2011, background): “Fragmentation in the moss system has previously shown to cause non-random extinction of mesostigmatid mites consistent with their being large-bodied, top predators (Gilbert et al. 1998, Gonzalez et al. 1998, Gonzalez and Chaneton 2002, Staddon et al. 2010).”
Realistically Low Species Evenness Does Not Alter Grassland Species-Richness-Productivity Relationships (2004, background): “Plant extinctions at the regional level (Fischer and Stocklin 1997, Duncan and Young 2000) and invertebrate extinctions at the local level (Gonzalez and Chaneton 2002) have been reported to be higher among rare species.”
Species evenness and productivity in experimental plant communities (2004, background): “…abundance, both because such species appear to be inherently vulnerable (Fischer and Stöcklin 1997, Rooney and Dress 1997, Duncan and Young 2000, Gonzalez and Chaneton 2002) and because chance events are likely to have a larger impact on small populations (MacArthur and Wilson 1967, Pimm et…”
