Beta diversity and latitude in North American mammals: testing the hypothesis of covariation (2004, background): “However, current models cannot explain satisfactorily the observed spatial patterns for some continents (Bokma et al. 2001, Hawkins and Diniz-Filho 2002) and some of the more basic features of those patterns are still insufficiently explored (Zapata et al. 2003).”
The Mid‐Domain Effect and Species Richness Patterns:What Have We Learned So Far? (2004, methodology): “In two dimensions, if polygons (representing geographic ranges) are randomly placed within a bounded area (for example, on the map of a continental area, for terrestrial species), a peak of polygon overlap (species richness) is produced near the center of the area (Ney-Nifle and Mangel 1999; Bokma e”
Seasonality, the latitudinal gradient of diversity, and Eocene insects (2010, result): “…diversity patterns, or including longitude as well as latitude, the hypothesis produces many equivocal or contradictory results, and some of its assumptions appear problematic (Bokma et al. 2001; Zapata et al. 2003, 2005, references therein; but see Colwell et al. 2004a; Currie and Kerr 2008).”
The elevational gradient in Andean bird species richness at the local scale: a foothill peak and a high‐elevation plateau (2005, result): “By contrast, other authors (Bokma and Mönkkönen 2000, Koleff and Gaston 2001, Bokma et al. 2001, Hawkins and Diniz-Filho 2002, Diniz-Filho et al. 2002, Zapata et al. 2003) have dismissed a significant influence of MDE on spatial richness patterns, criticizing MDE model assumptions as unrealistic,…”
Environmental and geometric constraints on Indo-Pacific coral reef biodiversity (2005, background): “Finally, there is a speciation–extinction model that exhibits an MDE ( Bokma et al. 2001 ).”
On the Generality of the Latitudinal Diversity Gradient (2004, result): “The mid-domain models were criticized for the structure of the null model (Bokma et al. 2001; Diniz et al. 2002) and for the restricted importance of mid-domain effects for narrow-ranging species (Jetz and Rahbek 2002), which may account for a large proportion of the tropical diversity.”
A comprehensive evaluation of predictive performance of 33 species distribution models at species and community levels (2019, background): “As discussed in previous studies, this is because dispersal processes, historical contingencies, and missing covariates (Foster et al. 2012) generate spatial variation in species communities (Bokma et al. 2001, Fernando et al. 2007, Kessler 2009).”
