Abstract:Empirical evidence has often shown a large-scale positive co-occurrence of biodiversity-rich and densely populated regions. This biogeographical pattern has important implications for conservation biology. Previous studies have supported two of the potential mechanisms behind this pattern: the distributions of biodiversity and of human beings tend to match climatic patterns, and human beings have settled in regions of higher habitat heterogeneity or they may have increased it. There has been little testing and… Show more
“…The results of Barbosa et al (2010) at the largest sampling grain contrast with the findings of Luck et al (2010), who examined the congruence between HPD and bird species richness across Australia at a grain size of 11 grid cells. Luck et al (2010) found that the positive correlation between HPD and species richness remained even after controlling for variation in sampling effort.…”

“…After accounting for variation in sampling effort and area, Barbosa et al (2010) find that the positive relationship between Carabid species richness and HPD across regions largely disappears. However, and most surprisingly, they find that the negative correlation between HPD and richness across 10 Â 10 km grid cells reverts to a positive correlation (although the partial r 2 is very small).…”

“…As Barbosa et al (2010) notes, variation in sampling effort has largely been ignored by researchers working on the HPD-species richness correlation, although it could reasonably be described as 'the elephant in the room'. Indeed, the positive correlation between HPD and species richness could simply be an artefact of greater sampling in areas with more people.…”

“…In our study (Barbosa et al, 2010), we tested whether a sampling artefact applies to the species-people correlation for carabids in Italy at three spatial grains of analysis. As the commentaries by Luck (2010) and McKinney (2010) point out, there has been little consideration of variation in sampling effort in previous regional studies of the coexistence of biodiversity and people.…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
