Allozymatic divergence between border populations of two cryptic species of the Drosophila buzzatii cluster species (Diptera: Drosophilidae)
(PERGAMON-ELSEVIER SCIENCE LTD, 2010)
Drosophila antonietae and Drosophila gouveai are allopatric, cactophilic, cryptic and endemic of South America species, which aedeagus morphology is considered the main diagnostic character. In this work, single close ...
Ecological and Spatial Patterns Associated with Diversification of the Shrub Genus Tetraglochin along Southern-Central Andes (Rosaceae)
(Springer, 2019-02-26)
In addition to the degree of geographical isolation (sympatry, parapatry, allopatry and peripatry), ecology can be an important factor promoting diversification of lineages, both by niche divergence as well as niche ...
Allopatric speciation in ticks: genetic and reproductive divergence between geographic strains of Rhipicephalus (Boophilus) microplus
(BioMed Central, 2009-02)
Background: The cattle tick, Rhipicephalus (Boophilus) microplus, economically impact cattle industry in tropical and subtropical regions of the world. The morphological and genetic differences among R. microplus strains ...
Ecological singularity of temperate mesopredatory myliobatoid rays (Chondrichthyes: Myliobatiformes)
(Csiro Publishing, 2016-06)
Many myliobatoid rays are important mesopredators, having significant effects on coastal benthic communities. In tropical and subtropical high-diversity oligotrophic ecosystems, they partition their trophic resources, which ...
Early stages of divergence: phylogeography, climate modeling, and morphological differentiation in the South American lizard Liolaemus petrophilus (Squamata: Liolaemidae)
(Wiley Blackwell Publishing, Inc, 2012-03)
This study examines the phylogeographic structure within the Patagonian lizard Liolaemus petrophilus and tests for patterns of between-clade morphological divergence and sexual dimorphism as well as demographic and niche ...
Body size and allometric shape variation in the molly Poecilia viviparaalong a gradient of salinity and predation
(BioMed Central, 2014-12)
Background: Phenotypic diversity among populations may result from divergent natural selection acting directly on traits or via correlated responses to changes in other traits. One of the most frequent patterns of correlated ...

(Biomed Central Ltd, 2014-12-04)
Background: Phenotypic diversity among populations may result from divergent natural selection acting directly on traits or via correlated responses to changes in other traits. One of the most frequent patterns of correlated ...
Ecological divergence and hybridization of Neotropical Leishmania parasites
(National Academy of Sciences, 2021)
New evidence on the systematic and phylogenetic position of Parides burchellanus (Lepidoptera : Papilionidae)
(Blackwell PublishingOxfordInglaterra, 2008)
Hierarchical determinants of the functional richness, evenness and divergence of a vertebrate predator assemblage
(2009)
Environmental factors are hypothesized to affect the functional diversity of assemblages hierarchically. First, ecological filters constrain the range of functional traits potentially displayed by an assemblage by determining ...
