Volcanism rather than climatic oscillations explains the shared phylogeographic patterns among ecologically distinct plant species in the southernmost areas of the South American Arid Diagonal
(Elsevier Gmbh, 2020-08)
Shared genetic patterns within a community of ecologically distinct species may reflect the role of past geoclimatic events imprinting species evolutionary history. Although Pleistocene glaciations are the most important ...
Testing species hypotheses in the mangrove genus Rhizophora from the Western hemisphere and South Pacific islands
(2020-01-01)
The determination of species limits is key to biology, with practical implications for conservation policy makers, lawyers and stakeholders. However, naming species may be a difficult task as interspecific hybridization ...
Molecular and morphological differentiation among Torrent Duck (Merganetta armata) populations in the Andes
(Wiley Blackwell Publishing, Inc, 2019-09)
Birds living in riverine environments may show weak population structure because high dispersal abilities required to track habitat dynamics can result in gene flow over broad spatial scales. Alternatively, the configuration ...
Recurrent connections between Amazon and Atlantic forests shaped diversity in Caatinga four-eyed frogs
(2016-05-01)
Aim: The Caatinga is a widespread but poorly known biome in South America. Its historical stability is controversial and different types of evidence provide support to contrasting hypotheses. We investigate how past biome ...
Multilocus phylogeography of the endemic and endangered angular angelshark (Squatina guggenheim) in the Southwest Atlantic Ocean
(2022-01-01)
The angular angelshark (Squatina guggenheim) is a coastal endangered angel shark from the Southwest Atlantic Ocean and one of the major bycatch victims. Despite major concerns about this species, little is known about its ...
Filogeografía comparativa de cuatro especies de reptiles escamados en el altiplano cundiboyacense, cordillera oriental de Colombia
(Universidad Nacional de ColombiaBogotá - Ciencias - Maestría en Ciencias - BiologíaDepartamento de BiologíaFacultad de CienciasBogotá, ColombiaUniversidad Nacional de Colombia - Sede Bogotá, 2021)
En el estudio de la distribución geográfica de la estructura genética intraespecífica y de los procesos y mecanismos subyacentes, el enfoque comparativo permite encontrar congruencias entre especies codistribuidas, y de ...
Physical mapping of the Nile tilapia (Oreochromis niloticus) genome by fluorescent in situ hybridization of repetitive DNAs to metaphase chromosomes - a review
(Elsevier B.V., 2004-03-05)
The Nile tilapia (Oreochromis niloticus) has received increasing scientific interest over the past few decades for two reasons: first, tilapia is an enormously important species in aquaculture worldwide, especially in ...
