DOES Bradypus tridactylus Linnaeus (Pilosa: Bradypodidae) OCCUR IN PANAMA? [PDF]

open access: yesTecnociencia, 2016
This note reports the observation of individuals of the genus Bradypus in Darien Forest, Panama, that strongly resemble Bradypus tridactylus rather than the twospecies reported for Panama. The presence of B.

Variación no alométrica en el cráneo del perezoso bayo Bradypus variegatus (Schinz, 1825) (Mammalia, Pilosa, Bradypodidae)

open access: yesGraellsia, 2019
El perezoso bayo Bradypus variegatus (Schinz, 1825) es un mamífero monomórfico, de ontogenia craneal poco conocida. En este estudio analizamos la alometría estática entre tamaño y forma, utilizando 21 especímenes diferentes de edades diversas.

Phylogenetic analysis of 16S mitochondrial DNA data in sloths and anteaters [PDF]

open access: yesGenetics and Molecular Biology, 2003
We sequenced part of the 16S rRNA mitochondrial gene in 17 extant taxa of Pilosa (sloths and anteaters) and used these sequences along with GenBank sequences of both extant and extinct sloths to perform phylogenetic analysis based on parsimony, maximum ...

Morphological analysis of teeth in Bradypus variegatus Schinz, 1825 (Mammalia, Bradypodidae)

open access: yesBiotemas, 2016
Among the sloth species, we may highlight the Bradypus variegatus, found especially in northeastern Brazil. Given the importance and scarcity of information about the digestive tract of wild animals, this article aims to describe dental morphology in ...

Melanism in Bradypus variegatus (Pilosa, Bradypodidae)

open access: yesNotas sobre Mamíferos Sudamericanos, 2020
In January 2011, a brown-throated three-toed sloth, Bradypus variegatus, was observed in an Atlantic Forest area from Rio de Janeiro, southeastern Brazil. The individual presented a blackish fur, indicating a melanic condition.

Brazilian distribution of Amblyomma varium Koch, 1844 (Acari: Ixodidae), a common parasite of sloths (Mammalia: Xenarthra)

open access: yesMemorias do Instituto Oswaldo Cruz, 2002
Amblyomma varium, commonly known in Brazil as the "carrapato-gigante-da-preguiça" (sloth's giant tick) is found from southern Central America to Argentina. The present study adds information on the geographical distribution of A.

A PCR‐RFLP assay for gender assignment in the three‐toed sloths (Bradypus, Pilosa, Bradypodidae)

open access: yesMolecular Ecology Resources, 2010
AbstractThe three‐toed sloths (Bradypus) are slow‐moving arboreal neotropical mammals. Understanding demographic variables (such as sex ratio) of populations is a key for conservation purposes. Nevertheless, gender assignment of Bradypus is particularly challenging because of the lack of sexual dimorphism in infants and in adults, particularly B ...

Morphology, molecular phylogeny, and taxonomic inconsistencies in the study ofBradypussloths (Pilosa: Bradypodidae) [PDF]

open access: yesJournal of Mammalogy, 2011
This study focuses on morphological and molecular data analyses, misidentifications, and phylogenetic inconsistencies regarding Bradypus variegatus (the brown-throated sloth) and B. tridactylus (the pale-throated sloth). Misidentifications were recorded on 75 of 313 museum specimens of Bradypus.

Architectural Properties of Sloth Forelimb Muscles (Pilosa: Bradypodidae)

open access: yesJournal of Mammalian Evolution, 2017
Tree sloths have reduced skeletal muscle mass, and yet they are able to perform suspensory behaviors that require both strength and fatigue resistance to suspend their body mass for extended periods of time. The muscle architecture of sloths is hypothesized to be modified in ways that will enhance force production to compensate for this reduction in ...

Life‐history traits and sexual dimorphism of the Atlantic forest maned sloth Bradypus torquatus (Xenarthra: Bradypodidae)

open access: yesJournal of Zoology, 2005
AbstractThis work presents new data from 48 maned sloths Bradypus torquatus captured between November 2002 and November 2003 in three regions of the Atlantic forest where the largest remnant populations of this species are found. Data from another long‐term study, carried out from 1994 to 1996 and from 1999 to the present (n=14), were also used, making
