Phylogeography of the Cactophilic Drosophila and Other Arthropods Associated with Cactus Necroses in the Sonoran Desert

open access: yesInsects, 2011
Studies on the population genetics, phylogenetic relationships, systematics and evolution of arthropods that inhabit necrotic tissue of cacti in the Sonoran Desert of North America are reviewed. These studies have focused upon several species of insects (

Dinosaurs from the Santonian–Campanian Atlantic coastline substantiate phylogenetic signatures of vicariance in Cretaceous North America

open access: yesRoyal Society Open Science, 2021
During the Cretaceous, diversifications and turnovers affected terrestrial vertebrates experiencing the effects of global geographical change. However, the poor fossil record from the early Late Cretaceous has concealed how dinosaurs and other ...

Basic problems of biogeography

open access: yesNatural History Sciences, 2018
Darwin interpreted most of biogeographic distributions as a consequence of dispersal events. The dispersionist approach lasted till the half of the XX century, but then an alternative paradigm arose: vicariantist biogeography.

Population genomic response to geographic gradients by widespread and endemic fishes of the Arabian Peninsula

open access: yesEcology and Evolution, 2020
Genetic structure within marine species may be driven by local adaptation to their environment, or alternatively by historical processes, such as geographic isolation.

PHYLOGENETIC RELATIONSHIPS AMONG WEST INDIAN XENODONTINE SNAKES (SERPENTES; COLUBRIDAE) WITH COMMENTS ON THE PHYLOGENY OF SOME MAINLAND XENODONTINES [PDF]

open access: yes, 1999
The evolutionary relationships of the West Indian (W. I.) xenodontine snake assemblage has been considered as either monophyletic or paraphyletic. Allozyme data from protein electrophoresis were used to estimate the phylogeny of the W. I.

Land masses and oceanic currents drive population structure of Heritiera littoralis, a widespread mangrove in the Indo‐West Pacific

open access: yesEcology and Evolution, 2020
Phylogeographic forces driving evolution of sea‐dispersed plants are often influenced by regional and species characteristics, although not yet deciphered at a large spatial scale for many taxa like the mangrove species Heritiera littoralis.

Invasive species and biodiversity crises: testing the link in the late devonian. [PDF]

open access: yesPLoS ONE, 2010
During the Late Devonian Biodiversity Crisis, the primary driver of biodiversity decline was the dramatic reduction in speciation rates, not elevated extinction rates; however, the causes of speciation decline have been previously unstudied.

Biogeographical patterns of the neotropical genus Battus Scopoli 1777 (Lepidoptera Papilionidae) [PDF]

open access: yes, 1993
A phylogenetic approach to the groups of species of the neotropical Troidines currently included in the genus Battus Scopoli 1777 has been conducted. In the light of historical and ecological processes of evolution in the neotropical biota, the cladogram

Vicarious goal satiation [PDF]

open access: yesJournal of Experimental Social Psychology, 2011
A signature feature of self-regulation is that once a goal is satiated, it becomes deactivated, thereby allowing people to engage in new pursuits. The present experiments provide evidence for vicarious goal satiation, a novel phenomenon in which individuals experience "post-completion goal satiation" as a result of unwittingly taking on another person ...
