Morphometrics and Taxonomy of Bats of the Genus Pteronotus (Subgenus Phyllodia) in Venezuela
TLDR
The analyses indicate that the subspecies endemic to the Península de Paraguaná, P. p. Expand
Molecular Systematics of Mouse Opossums (Didelphidae: Marmosa): Assessing Species Limits using Mitochondrial DNA Sequences, with Comments on Phylogenetic Relationships and Biogeography
TLDR
Preliminary phylogenetic analyses of sequence data from the mitochondrial cytochrome-b gene representing 12 of the 14 morphologically defined taxa recently treated as valid species of Marmosa (Marmosa) in the aforementioned revisionary work support the recognition of M. isthmica and M. simonsi as species distinct from M. robinsoni, and the recognitionof M. waterhousei asspecies distinct fromM. Expand
Phylogenetic Relationships of Mouse Opossums (Didelphidae, Marmosa) with a Revised Subgeneric Classification and Notes on Sympatric Diversity
TLDR
These clades have broadly overlapping geographic distributions, especially in western Amazonia, where the arboreal insectivorous-frugivorous niche of Marmosa is apparently partitioned among multiple sympatric congeners. Expand
Can biotic interactions cause allopatry? Niche models, competition, and distributions of South American mouse opossums
TLDR
The results and a review of numerous studies in whichBiotic interactions restrict species distributions support a previously overlooked phenomenon: biotic interactions can isolate populations of a species. Expand
Faunal nestedness and species–area relationship for small non-volant mammals in “sky islands” of northern Venezuela
We study the biogeography of small non-volant mammals in mesic montane sky islands of northern Venezuela. Fieldwork, examination of museum specimens, and critical use of literature yielded speciesExpand
Chapter 2. Taxonomy, Distribution, and Natural History of the Genus Heteromys (Rodentia: Heteromyidae) in Central and Eastern Venezuela, with the Description of a New Species from the Cordillera de
Abstract Heteromys anomalus is widely distributed along the Caribbean coast of South America and had been considered the only spiny pocket mouse present in Venezuela for several decades. RecentExpand
Taxonomy based on science is necessary for global conservation
Author(s): Thomson, Scott A; Pyle, Richard L; Ahyong, Shane T; Alonso-Zarazaga, Miguel; Ammirati, Joe; Araya, Juan Francisco; Ascher, John S; Audisio, Tracy Lynn; Azevedo-Santos, Valter M; Bailly,Expand
Photography-based taxonomy is inadequate, unnecessary, and potentially harmful for biological sciences.
The question whether taxonomic descriptions naming new animal species without type specimen(s) deposited in collections should be accepted for publication by scientific journals and allowed by theExpand
Are we overestimating the niche? Removing marginal localities helps ecological niche models detect environmental barriers
TLDR
Test whether this issue obfuscates detection of an obvious environmental barrier existing in northern Venezuela – that of the hot and xeric lowlands separating the Península de Paraguaná from mainland South America is tested. Expand
The Taxonomic Status of Mazama bricenii and the Significance of the Táchira Depression for Mammalian Endemism in the Cordillera de Mérida, Venezuela
TLDR
ENM analyses revealed the existence of suitable climatic conditions for M. rufina in the Táchira Depression during the last glacial maximum and even at present, suggesting that gene flow between populations in the CO and CM may have occurred until at least the beginning of the current interglacial period and may continue today.
