Journal ArticleDOI
What determines conformity to Bergmann's rule?
TL;DR: It is suggested that species with large geographical ranges are likely to encounter significant heterogeneity in those factors that influence body size, and are thus likely to exhibit size clines, and that the spatial distribution of key resources within the species range constitutes a significant predictor of carnivore body size.
Journal ArticleDOI
Population Genetics of Speciation in Two Closely Related Wild Tomatoes (Solanum Section Lycopersicon)
TL;DR: It is suggested that speciation occurred under residual gene flow, implying that natural selection is one of the evolutionary forces driving the divergence of these tomato species.
Journal ArticleDOI
Inter-specific hybridization underlies phenotypic variability in Daphnia populations.
Hans Georg Wolf,Mona A. Mort +1 more
TL;DR: Electrophoretic investigations of allozyme-patterns in morphologically typical individuals reveal that each species is fixed for a different allele at the GOT locus, consistent with the assumption that morphological intermediates are formed via interspecific hybridization.
Journal ArticleDOI
The evolution of species concepts and species recognition criteria in plant pathogenic fungi
TL;DR: The Genealogical Concordance Phylogenetic Species Recognition is compared with other species recognition criteria and it is shown that it provides a better discrimination for delimiting species.
Journal ArticleDOI
Coadaptation and taxonomic differentiation of sperm and spermathecae in featherwing beetles.
TL;DR: In each species of the Bambara invisibilis group on Sri Lanka the form of the sperm is highly coadapted structurally with that of the spermatheca, suggesting an important functional morphological relationship between these complementary male and female reproductive structures.
