A new species of Serracutisoma (Opiliones: Gonyleptidae: Goniosomatinae) from the coastal Atlantic Rain Forest of Paraná and São Paulo states, Brazil

open access: yesZoologia (Curitiba), 2014
Serracutisoma gnaspinii sp. nov. is described from the coastal Ombrophylous Dense Atlantic Rain Forest of Paraná and São Paulo states. It differs from other Serracutisoma by having a retrolateral row of spines on femur IV, a rounded white-mark on the ...

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 ...

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.

Diversification at the narrow sea-land interface in the Caribbean: phylogeography of endemic supralittoral Ligia isopods

open access: yesFrontiers in Ecology and Evolution, 2014
Phylogeographic studies have provided valuable insights into the evolutionary histories and biodiversity of different groups in the Caribbean, a region that harbors exceptional terrestrial and marine biodiversity.

But they move! Vicariance and dispersal in southern South America: Using two methods to reconstruct the biogeography of a clade of lizards endemic to South America. [PDF]

open access: yesPLoS ONE, 2018
This study aims to identify events that modeled the historical biogeography of Phymaturus, using three methodologies: Spatial Analysis of Vicariance (VIP), Statistical Dispersal-Vicariance Analysis (S-DIVA), and Bayesian Binary Method MCMC (BBM).

Pleistocene Aquatic Refuges Support the East–West Separation of the Neotropical Catfish Trichomycterinae (Siluriformes: Trichomycteridae) and High Diversity in the Magdalena, Guiana, and Paraná-Paraguay Basins

open access: yesDiversity, 2023
(1) Background: Trichomycterinae represent 60% of the species in the family and, while seven genera comprise 1–3 species each, Trichomycterus and Cambeva have over 180 known species between them.

Pleistocene Legacies in the Contemporary Population Genetic Structure of an Acid-Specialised Crayfish, the Threatened Sand Yabby <i>Cherax robustus</i>. [PDF]

open access: yesEcol Evol
This study describes the contemporary genetic structure of a vulnerable short‐range endemic crayfish which is restricted to the heavily fragmented heathland‐peatland complexes of southeast Queensland across a range of approximately 200 km2. Using high‐resolution genome‐wide SNP sequencing, we estimate that population divergence in this species ...

Phylogenetic paleobiogeography of Late Ordovician Laurentian brachiopods [PDF]

open access: yesEstonian Journal of Earth Sciences, 2014
Phylogenetic biogeographic analysis of four brachiopod genera was used to uncover large-scale geologic drivers of Late Ordovician biogeographic differentiation in Laurentia. Previously generated phylogenetic hypotheses were converted into area cladograms,
