Signature of the Paleo-Course Changes in the São Francisco River as Source of Genetic Structure in Neotropical Pithecopus nordestinus (Phyllomedusinae, Anura) Treefrog

open access: yesFrontiers in Genetics, 2019
Historical processes that have interrupted gene flow between distinct evolutionary lineages have played a fundamental role in the evolution of the enormous diversity of species found in the Neotropical region.

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.

Coming to America: Multiple Origins of New World Geckos [PDF]

open access: yes, 2011
Geckos in the Western Hemisphere provide an excellent model to study faunal assembly at a continental scale. We generated a time-calibrated phylogeny, including exemplars of all New World gecko genera, to produce a biogeographic scenario for the New ...

Evolutionary diversifications of plants on the Qinghai-Tibetan Plateau

open access: yesFrontiers in Genetics, 2014
The Qinghai-Tibetan Plateau (QTP) is the highest and one of the most extensive plateaus in the world. Phylogenetic, phylogeographic and ecological studies support plant diversifications on the QTP through multiple mechanisms such as allopatric ...

Spotlight on islands.On the origin and diversification of an ancient lineage of the Italian wall lizard Podarcis siculus in the western Pontine Islands [PDF]

open access: yes, 2018
Groups of proximate continental islands may conceal more tangled phylogeographic patterns than oceanic archipelagos as a consequence of repeated sea level changes, which allow populations to experience gene flow during periods of low sea level stands and

Synopsis of the Evippinae (Araneae, Lycosidae) of Israel, with description of a new species

open access: yesEuropean Journal of Taxonomy, 2021
Evippinae (Araneae, Lycosidae) is a subfamily of old-world lycosids, comprising six genera and 67 species, most of them typically found in xeric habitats.

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,

Regional Genetic Structure in the Aquatic Macrophyte Ruppia cirrhosa Suggests Dispersal by Waterbirds [PDF]

open access: yes, 2017
The evolutionary history of the genus Ruppia has been shaped by hybridization, polyploidisation and vicariance that have resulted in a problematic taxonomy. Recent studies provided insight into species circumscription, organelle takeover by hybridization,

Historical biogeography of Thyrsophorini psocids and description of a new neotropical species of Thyrsopsocopsis (Psocodea: Psocomorpha: Psocidae)

open access: yesEuropean Journal of Taxonomy, 2016
When based on phylogenetic proposals, biogeographic historic narratives have a great interest for hypothesizing paths of origin of the current biodiversity.
