One of the first cryptic mammal species discovered, when it was separated from the morphologically similar R. tumida (= R. bickhami) based on karyological studies. Karyotype of 2n = 42 of R. genowaysi is identical to that observed in R. velilla, but these species are genetically distinct; their ranges do not overlap. R. genowaysi is morphologically very similar to other species within the R. tumida complex and is sympatric with R. bickhami (2n = 34). Monotypic. Distribution. Two nearby localities in Pacific lowlands of S Chiapas, S Mexico. in Vespertilionidae

Data from: Benefits of increased colonist quantity and genetic diversity for colonization depend on colonist identity
Larger numbers of colonists can be more likely to establish and spread due to the benefits provided by either more individuals (quantity) or a greater diversity of genotypes or phenotypes (genetic diversity). However, the value of higher colonist quantity or genetic diversity varies widely across studies, leaving a great deal of uncertainty in how these respective mechanisms affect colonization success. This variability is potentially driven by differences in which traits are present in respective colonist pools ('colonist identity'). Studies with high-performing colonizers (e.g. genotypes pre-adapted to the colonizing environment) may find increasing quantity or diversity to be beneficial because it increases the chance high-performers are sampled, while studies with no high-performers may find no effects of quantity or diversity. Alternatively, quantity and genetic diversity may play little to no role if the smallest populations already contain high-performing colonists because there is no scope for a sampling effect to operate. We conducted a field mesocosm experiment to determine if variability in the benefits provided by increased quantity or genetic diversity relates to colonist traits. Nine distinct genotypes of <i>Daphnia pulex</i>, characterized also by phenotype, were introduced in 'single' (one individual) or 'many' (nine individuals) introduction quantities and at 'low' (monoclonal) and 'high' (mixed genotypes) genetic diversities. We found that larger-bodied <i>D. pulex</i> genotypes benefited less from increased colonist quantity, while increasing genetic diversity tended to have a lower effect on higher growth rate genotypes. Our results show that the trait values of the colonists can determine the benefits gained when colonist quantity or genetic diversity are increased, with potential applications to future research and practical efforts to promote, or prevent, population establishment.
Data from: Maintenance of genetic and morphological identity in two sibling Syrrhopodon species (Calymperaceae, Bryopsida) despite extensive introgression
Bryophytes are a group of land plants wherein the role of hybridization has long been challenged. Using Genotyping by Sequencing to circumvent the lack of molecular variation at selected loci previously used for phylogeny and morphology, we determine the level of genetic and morphological divergence and reproductive isolation between the sibling Syrrhopodon annotinus and S. simmondsii (Calymperaceae, Bryopsida) that occur in sympatry but in different habitats in lowland Amazonian rainforests. A clear morphological differentiation and a low (0.06), but significant Fst derived from the analysis of 183 SNPs were observed between the two species. Conspecific pairs of individuals consistently exhibited higher average kinship coefficients along a gradient of geographic isolation than interspecific pairs. The weak, but significant genetic divergence observed is consistent with growing evidence that ecological specialization can lead to genetic differentiation among bryophyte species. Nevertheless, the spatial genetic structures of the two species were significantly correlated, as evidenced by the significant slope of the Mantel test based on kinship coefficients between pairs of interspecific individuals and the geographic distance separating them. Interspecific pairs of individuals are thus more closely related when they are geographically closer, suggesting that isolation-by-distance is stronger than the interspecific reproductive barrier and pointing to interspecific gene flow. We conclude that interspecific introgression, whose role has long been questioned in bryophytes, may take place even in species wherein sporophyte production is scarce due to dioicy, raising the question as to what mechanisms maintain differentiation despite weak reproductive isolation.
