Phylogeny and temporal diversification of Calomys (Rodentia, Sigmodontinae): implications for the biogeography of an endemic genus of the open/dry biomes of South America.
Mosaics of convergences and noise in morphological phylogenies: what's in a viverrid-like carnivoran?
These results support the removal from the traditionally held Viverridae of several viverrid-like taxa into three distinct families: Nandiniidae, Prionodontidae (Prionodon), and the newly defined Eupleridae (including Cryptoprocta, Fossa, Eupleres plus all "mongoose-like" Malagasy taxa).
Taxonomic revision of the long-nosed armadillos, Genus Dasypus Linnaeus, 1758 (Mammalia, Cingulata)
The aim is to revise the taxonomy of the long-nosed armadillos and properly define the taxa and to designate a lectotype for D. novemcinctus and a neotype for Loricatus hybridus.
Host-plant dependent wing phenotypic variation in the neotropical butterfly Heliconius erato
It is proposed that this variation in forewing size and shape in the butterfly Heliconius erato phyllis can be an important factor in resource specialization and partner recognition, possibly triggering reproductive isolation and sympatric speciation in phytophagous insects.
Combining geometric morphometrics and pattern recognition to identify interspecific patterns of skull variation: case study in sympatric Argentinian species of the genus Calomys (Rodentia:…
This work applies statistical procedures from the field of pattern recognition to three-dimensional geometric morphometric data based on skull landmarks to identify sympatric species C. laucha, C.musculinus and Calomys venustus.
Phylogenetic systematics and tempo of evolution of the Viverrinae (Mammalia, Carnivora, Viverridae) within feliformians: implications for faunal exchanges between Asia and Africa.
Cranial and chromosomal geographic variation in manatees (Mammalia: Sirenia: Trichechidae) with the description of the Antillean manatee karyotype in Brazil
It is hypothesize that the Amazon River mouth may be acting as a reproductive barrier for the T. m.
Inferring adaptation within shape diversity of the humerus of subterranean rodent Ctenomys
Analysis of the humerus of four species of Ctenomys from southern Brazil revealed unexpected patterns because C. lami was the species phenetically more distant from C. flamarioni and not C. torquatus as expected from ecological data and phylogenetic relationships.
INTERSPECIFIC PATTERNS OF SKULL VARIATION BETWEEN SYMPATRIC BRAZILIAN VESPER MICE: GEOMETRIC MORPHOMETRICS ASSESSMENT
The combination of geometric morphometrics and pattern recognition techniques seems suitable for systematic analyses aimed at elucidating interspecific patterns of morphological variation in closely related species in field studies and museum specimens.
The correct name of the endemic Dasypus (Cingulata: Dasypodidae) from northwestern Argentina.
The correct name for the long-nosed armadillo of intermediate size occurring in the Argentinean provinces of Jujuy and Salta is Dasypus mazzai Yepes 1933, a distinct endemic species from northwestern Argentina undistinguishable from D. yepesi.
