“…In temporary ponds, the strength of this relationship measured as the z value of the power (log–log) model varied largely across different systems, suggesting additional important factors involved in structuring pond diversity (Alahuhta et al, 2021). A consistent external contributor to the diversity of ecological islands is the surrounding habitat matrix (Csergő et al, 2014; Martín‐Queller et al, 2017; Matias et al, 2013). By varying the properties of the landscape matrix, e.g.…”

“…While islands have been the classic focus of isolation effects, isolation can also emerge on the mainland, due to either large geographic distances between populations (in continuous and recently fragmented habitats, McIntyre and Hobbs 1999, Watson 2002, Laurance 2008), or environmental discontinuities between suitable habitat patches in ecological islands (Csergő et al 2014, Tapper et al 2014, Steinbauer et al 2016). However, mainland isolation is likely to differ from classic marine island isolation, as mainland habitat islands lack an abrupt saltwater barrier and experience higher spatial or temporal connectivity (Haila 2002, 2002, Driscoll et al 2013, Ó Marcaigh et al 2021).…”

Spatial isolation is a key driver of population‐level variability in traits and genotypes worldwide. Geographical distance between populations typically increases isolation, but organisms face additional environmental barriers when dispersing between suitable habitat patches. Despite the predicted universal nature of the causes of isolation, global comparisons of isolation effects across taxa and geographic systems are few. We assessed the strength of isolation due to geographic and macroclimatic distance for paired marine island and paired mainland populations within the same species. Our meta‐analysis included published measurements of phenotypic traits and neutral genetic diversity from 1608 populations of 108 plant and animal species at a global scale. As expected, phenotypic differentiation was higher between marine islands than between populations on the mainland, but we found no consistent signal for differences in spatial patterns of neutral genetic diversity between the two systems. Geographic distance had comparatively weak effects on the spatial patterns of phenotypes and neutral genetic diversity. These results suggest that spatial patterns of phenotypic variation are determined by eco‐evolutionary pressures that differ more between islands than between mainland populations, while the spatial variability of neutral genetic diversity might be shaped by rather similar processes in the two systems. Our approach demonstrates that global biodiversity models that include island biology studies may progress our understanding of the interacting effects of spatial habitat structure, geographic‐ and environmental distances on biological processes underlying spatial population variability. We formulate future research directions for empirical tests and global syntheses in the field.

“…Although some studies have correlated genetic diversity with species diversity (e.g., Avolio et al., 2012; Blum et al., 2012; Csergö, Hufnagel, & Höhn, 2014; Wei & Jiang, 2012), few have been conducted in México (outside the REBISO; e.g., Simental-Rodríguez et al., 2014; Wehenkel, Bergmann, & Gregorius, 2006) and none has related genetic diversity with the ecological function of species as intended in this research. The aim of this study was to determine the genetic diversity of a random sample of bat species in a semievergreen tropical forest at REBISO and explore whether this genetic diversity is correlated with the ecological role they play in the ecosystem.…”

Species that are functionally equivalent but with little taxonomical relationship may display similar genetic patterns if the ecological function evolves genetically in the same way. This study investigated the levels of genetic diversity in the D-Loop gene of random samples collected from 21 bat species inhabiting El Ocote Biosphere Reserve (REBISO, for its acronym in Spanish), and whether the genetic diversity pattern could be associated with the ecological role. Genetic differences between functional groups, localities, and species were evaluated through generalized linear models using the Gaussian distribution error family for nucleotide diversity (p) and the Poisson family for haplotype diversity (h) and segregating sites (s). To study the clustering pattern of species based on nucleotide variation, genetic distances (Kimura's two-parameter model) between functional groups were calculated, and a Principal Components Analysis on genetic diversity parameters was run. Most of the species analyzed (20) maintained genetic diversity levels ranging from medium to high in all genetic diversity estimators. According to genetic distances, the species with the same ecological function shared a greater number of nucleotide substitutions, with some exceptions. The Principal Components Analysis did not detect any genetic structure in relation to the ecological function. Our study found no association between the diversity of the D-Loop gene and ecological function; nonetheless, it confirms the importance of REBISO as a reservoir of bat species richness and genetic diversity in Mexico.
