Bradypus Pygmaeus (Pilosa: Bradypodidae)

  title={Bradypus Pygmaeus (Pilosa: Bradypodidae)},
  author={Virginia Hayssen},
Abstract Bradypus pygmaeus Anderson and Handley, 2001, the pygmy three-toed sloth, is a dwarf bradypodid that is 1 of 4 species of Bradypus. It is easily distinguished from its conspecifics by its small size and restricted distribution (endemic to Isla Escudo de Veraguas of Bocas del Toro, off the Caribbean coast of Panama). B. pygmaeus is found exclusively in red mangroves at sea level, and it is listed as critically endangered by the International Union for the Conservation of Nature and… 
Choloepus hoffmanni (Pilosa: Megalonychidae)
A high-canopy folivore with a disjunct range with a northern population in Central America and northern South America and a southern population in South America, C. hoffmanni is listed as “Least Concern” by the International Union for Conservation of Nature and Natural Resources.
Digital Cranial Endocasts of the Extinct Sloth Glossotherium robustum (Xenarthra, Mylodontidae) from the Late Pleistocene of Argentina: Description and Comparison with the Extant Sloths
This study, which represents the first exhaustive analysis of digital endocasts of a fossil sloth, reveals the importance of the application of new methodologies, such as CT scans, for elucidating the evolutionary history of this peculiar mammalian clade.
Ecophysiological steps of marine adaptation in extant and extinct non‐avian tetrapods
Ecophysiological features in extant non-avian marine tetrapods representing 31 marine colonizations are reviewed to test whether there is a common pattern across higher taxonomic groups, such as mammals and reptiles, to reconstruct the evolutionary history of marine adaptation.
Sloths in the city: unexpectedly high density of pale-throated three-toed sloths (Bradypus tridactylus) found in an urban forest patch in Paramaribo, Suriname
In October 2012 individuals associated with the Green Heritage Fund Suriname organized a rescue of arboreal mammals displaced during deforestation of a 6.8 ha plot in northwest Paramaribo. Rescued or


Captive health and husbandry of the Bradypodidae
Historically, three-toed sloths have presented poor maintenance records in captivity, rarely exceeding captive lifespans of more than 1 month, but this is a species that can be maintained more successfully in captivity with application of established care techniques from a successful collection.
The islands of Bocas del Toro, Panama, were sequentially separated from the adjacent mainland by rising sea levels during the past 10,000 years. Three-toed sloths (Bradypus) from five islands are
Phylogenetic relationships among sloths (Mammalia, Xenarthra, Tardigrada): the craniodental evidence
The results imply that the split between the two extant sloth genera is ancient, dating back perhaps as much as 40 Myr, and that the similarities between these two taxa present one of the most dramatic examples of convergent evolution known among mammals.

The vast terrain between Panama and Tierra del Fuego contains some of the world's richest mammalian fauna, but until now it has lacked a comprehensive systematic reference to the identification,
Cranial osteology and function in the tree sloths, Bradypus and Choloepus. American Museum novitates ; no. 2739
In sloths, the retention or loss of elongate anterior teeth and the ramifications that follow from these changes can be regarded as the most important factors in explaining the differences seen in cranial structure between Choloepus andSome megalonychids and Bradypus and some megatheriids.
Phylogenetic relationships among ascomycetes: evidence from an RNA polymerse II subunit.
Findings show that a slowly evolving protein-coding gene such as RPB2 is useful for diagnosing phylogenetic relationships among fungi, and suggests that fruiting body formation and forcible discharge of ascospores were characters gained early in the evolution of the Ascomycota.
