An update on the physiology of two- and three-toed sloths BJMBR
Gilmore,D.P.; Da-Costa,C.P.; Duarte,D.P.F..
Physiological and pharmacological research undertaken on sloths during the past 30 years is comprehensively reviewed. This includes the numerous studies carried out upon the respiratory and cardiovascular systems, anesthesia, blood chemistry, neuromuscular responses, the brain and spinal cord, vision, sleeping and waking, water balance and kidney function and reproduction. Similarities and differences between the physiology of sloths and that of other mammals are discussed in detail.

Anatomical aspects of the nerves of the leg and foot of the giant anteater (Myrmecophaga tridactyla, Linnaeus, 1758) Arq. Bras. Med. Vet. Zootec.
Cruz,V.S.; Cardoso,J.C.; Araújo,L.B.M.; Souza,P.R.; Silva,M.S.B.; Araújo,E.G..
Although distal stifle joint nerve distribution has been well established in domestic animals, this approach is scarcely reported in wild animals. Therefore, the aim of this study was to describe the nerves of the leg and foot of Myrmecophaga tridactyla with emphasis on their ramification, distribution, topography and territory of innervation. For this purpose, six adult cadavers fixed and preserved in 10% formalin solution were used. The nerves of the leg and foot of the M. tridactylawere the saphenous nerve (femoral nerve branch), fibular and tibial nerves and lateral sural cutaneous nerve (branches of the sciatic nerve) and caudal sural cutaneous nerve (tibial nerve branch). The saphenous nerve branches to the skin, the craniomedial surface of the leg,...

Dental occlusal surface area in relation to body mass, food habits and other biological features in fossil xenarthrans Ameghiniana
Vizcaíno,Sergio F.; Bargo,M. Susana; Cassini,Guillermo H..
The Xenarthra includes the most intriguing mammals from the Cenozoic of South America: the glyptodonts (Cingulata) and the ground sloths (Tardigrada). Their masticatory apparatuses are diverse and peculiar, with a strongly reduced, hypselodont dentition that lacks enamel and displays different degrees of lobation. The goal of this study is to investigate the relationship between dental occlusal surface area (OSA) and diet, and other physiological factors in fossil xenarthrans. Over one hundred and fifty specimens, including living herbivorous epitherians and both extinct and living xenarthrans, were measured and photographed, and their OSA estimated and plotted against body mass. For most fossil xenarthrans OSA is smaller than expected for extant...

Differentiation and characterization of burrows of two species of armadillos in the Brazilian Cerrado RChHN
Guilherme Trovati,Roberto.
BACKGROUND: Signs left by some mammals such as tracks, trails, burrows, scratches, feces, hair, and others can be an important tool for species identification. This study was conducted in the Itirapina Ecological Station, in the southern Brazilian Cerrado, whose main objectives were to (1) compare the burrow morphometric variables of Cabassous unicinctus and Euphractus sexcinctus and (2) check for differences in the occurrence of foraging burrows in two different environments: areas with vegetation (shrubby grassland) and areas without vegetation (roads). The collected measures of armadillo's burrows have been width, height, depth, and angle relative to the soil. To record foraging burrows (<70 cm), the linear transect methodology was used...

Differentiation of Xenarthra (Mammalia) species through the identification of their fecal bile acid patterns: An ecological tool RChHN
ARAUJO,M. SOLEDAD; CIUCCIO,MARIANO; CAZON,ADA V; CASANAVE,EMMA B.
The analysis of feces is a fundamental tool for field work, especially to identify the presence of certain species in an area. Fecal bile acids and their relative concentration follow patterns that are species-specific, and can be characterized by Thin Layer Chromatography (TLC). This technique has been used for differentiating feces of several mammal species; however it has never been used for Xenarthra species. In this work, 96 feces of Xenarthra species were analyzed by TLC to determine the bile acid pattern. The species were: Zaedyus pichiy (n = 10), Chaetophractus vellerosus (n = 5), Chaetophractus villosus (n = 57), Dasypus kybridus (n = 4), Priodontes maximus (n = 2), Tamanduá tetradactyla (n = 14) and Myrmecophaga tridactyla (n = 4). There were...

Establishment of an anesthetic protocol for semen collection by electroejaculation in six-banded armadillos (Euphractus sexcinctus Linnaeus, 1758) Arq. Bras. Med. Vet. Zootec.
Sousa,P.C.; Amorim,R.N.L.; Lima,G.L.; Paiva,A.L.C.; Paula,V.V.; Freitas,C.I.A.; Silva,A.R..
ABSTRACT The aim was to verify the effects of different anesthetic protocols used during electroejaculation (EEJ) in six-banded armadillos (Euphractus sexcinctus). Four sexually matured animals were physically restrained and subjected to semen collection by the EEJ following three treatments: The control group consisted of no use of anesthesia; in the others, the anesthetic combinations xylazine/ketamine/propofol or butorphanol/ ketamine/propofol were administered. For each group, twelve procedures were conducted for EEJ. Semen was evaluated for volume, color, aspect, motility, sperm concentration, morphology, viability, and functional membrane integrity. The highest efficiency (100% ejaculates) was achieved when the control group was used; the...

Histological Study of the Salivary Glands in Zaedyus pichiy (Mammalia, Xenarthra, Dasypodidae) International Journal of Morphology
Estecondo,Silvia; Codón,Stella Maris; Casanave,Emma Beatriz.
The histology of the salivary glands of the armadillo Zaedyus pichiy (Desmarest, 1804) was studied. Three pairs of major compound tubuloacinar salivary glands, parotid, submandibular and sublingual, were distinguished. The parotid gland is histologically a serous gland. The submandibular gland consists of two lobes. The anterior lobe is composed of mixed and serous acini. The posterior lobe is predominantly mucous. There is a reservoir or salivary bladder, related with the anterior lobe. The sublingual gland is mixed, composed of mucous acini with scattered serous demilunes

Kinematic description of the vertical climbing of Dasypus novemcinctus (Xenarthra, Dasypodidae): the first report of this ability in armadillos Mastozool. neotrop.
Costa,Fabiana R; Clerici,Giannina P; Rosa,Patrícia S; Ribeiro,Leonardo L; Rocha-Barbosa,Oscar.
Armadillos are well-known quadrupeds whose digging abilities classify them differently into many fossorial categories. This is the first time a kinematic description is provided on the vertical climbing sequences performed by these animals, more specifically by the nine-banded armadillo Dasypus novemcinctus. After an opportunistic observation of climbing behavior, video recording sessions were setup to document wire mesh climbing. The individuals climbed up to its top showing four distinct ways of vertical progression, such as lat­eral and diagonal-sequences as well as few styles that resemble the asymmetrical motions used by quadrupeds on land. Sharp claws were used as strategic points of attachment on a substrate, and tails provided additional support...

Modelo de suprimento sanguíneo do intestino grosso do tamanduá bandeira (Myrmecophaga tridactyla) Ciência Rural
Souza,Ana Lúcia Rezende de; Rezende,Lorenna Cardoso; Mortoza,Amanda Rocha; Ferreira,Jussara Rocha.
Em seis animais adultos Myrmecophaga tridactyla estudou-se o modelo de suprimento sanguíneo do intestino grosso, que é dependente das artérias mesentérica cranial (AMCr) e caudal (AMC). Os espécimes coletados conforme as normas do IBAMA (Instituto Brasileiro do Meio Ambiente e dos Recursos Naturais Renováveis) foram perfundidos com água (40 C), injetados com látex corado, fixados em formol e conservados em solução alcoólica (50%). O mesocólon está disposto na linha sagital mediana e fixa o intestino grosso à parede dorsal do abdome. Derivaram da AMC: a artéria retal cranial, sete a 14 artérias cólicas e uma ou duas artérias ileocólicas, que apresentaram anastomoses de irrigação com a AMCr. A AMC finaliza-se na borda mesocólica das alças intestinais,...

Morphology and Histological Annual Changes of the Oviduct of Chaetophractus villosus (Mammalia, Xenarthra, Dasypodidae) International Journal of Morphology
Codón,Stella Maris; Casanave,Emma Beatriz.
The morphological features of the oviduct in the armadillo Chaetophractus villosus (Desmarest, 1804) were studied. In the simple columnar epithelium, ciliated cells, secretory cells, and cells of the bottom of the folds are described. The most remarkable findings are the increase in number of ciliated cells, when present, from the fimbriae to the uterus, being the isthmus practically lined by ciliated cells, and that secretory cells are more abundant in the apical zone of the ampulla and fimbriae, than in the isthmus. Morphological changes along the year in the different portions are described.

Rezende,L. C; Monteiro,J. M; Carvalho,P; Ferreira,J. R; Miglino,M. A.
The macroscopic anatomy and vascularization of the stomach compartments of Bradypus torquatus were examined in five animals from the University of São Paulo College of Veterinary Medicine and Zootechny collection. The method included aqueous perfusion of the arterial network, colored latex injection, fixation in formaldehyde (10%) and preservation in Laskovisk solution. Dissections were performed under mesoscopic light and photo documentations were performed for description and data analysis. In these animals, the largest abdominal organ was the stomach, which internally presented the cardiac, fundic and prepyloric regions, subdivided in six compartments (cardiac right, middle and left; fundic; pre-pyloric I and II). The stomach was irrigated by the left...

Morphology of the Diaphragm Muscle in Southern Tamandua (Tamandua tetradactyla) and its Importance in Cases of Traumatic Hernia Anais da ABC (AABC)
AZEVEDO,ÉRICA F.S.; SILVA,DANIELA R. COSTA E; NATIVIDADE,TAMIRES V.S.; GIESE,ELANE G.; LIMA,ANA RITA DE; SOARES,PAOLA C.; BRANCO,ÉRIKA.
ABSTRACT The wall of the diaphragm can be affected by changes caused by physical trauma, allowing the passage of viscera between the abdominal cavity and thoracic cavity, thus reducing the space for pulmonary expansion, leading to the formation of hernia and possible death. Thus, we aimed to characterize, size and determine the topography of the diaphragmatic muscle in the Southern Tamandua, since clinical and surgical activities in wild animals have become a reality more and more present in veterinary medicine. We used six adult animals, x-rayed and dissected, followed by collection of fragments of muscular portions for histological analysis. Initially we observed that the animals presented 17 thoracic vertebrae, 3 lumbar vertebrae and 5 sacral vertebrae....

New records of the southern naked-tailed armadillo Cabassous unicinctus unicinctus Linnaeus, 1758 (Cingulata: Dasypodidae) in Brazil Biota Neotropica
Anacleto,Teresa Cristina da Silveira; Godoy,Leandro Perez; Tubelis,Darius Pukenis.
The geographic distribution of Cabassous unicinctus is poorly known due to the low number of available records. Two subspecies with distributions limited by the Amazonas River were recognized in 1980. Cabassous u. unicinctus has been found north of this river, while C. u. squamicaudis occurs in areas south of the river. This study aimed to update the distribution records of C. u. unicinctus in Brazil. We compiled records from literature, museum collections and field studies. New records of this subspecies were obtained from the Brazilian states of Acre, Pará, Rondônia and Mato Grosso. These records enlarge a geographic distribution of C. u. unicinctus to Amazonian and Cerrado biomes, regions located south of the Amazon River.

Notice on the ocurrence of supernumerary teeth in the two-toad sloths Choloepus didactylus and C. hoffmanni Mastozool. neotrop.
McAfee,Robert K; Naples,Virginia L.
Supernumerary teeth occur in nearly all modern mammalian orders, although no previous cases have been published for extant pilosans. We report here three specimens of the sloth genus Choloepus, two C. hoffmanni and one C. didactylus, exhibiting supernumerary teeth. All duplicated teeth are maxillary, and all but one on the right side. One C. hoffmanni bears an additional left tooth, suggesting duplication is neither species nor toothrow-side specific. Sloth teeth erupt as simple rounded cones and the different "cusp" patterns characteristic of each extant and extinct genus arise from wear and the differential spacing of upper versus lower dentitions.

Novel 12S mtDNA findings in sloths (Pilosa, Folivora) and anteaters (Pilosa, Vermilingua) suggest a true case of long branch attraction Genet. Mol. Biol.
Barros,Maria Claudene; Sampaio,Iracilda; Schneider,Horacio.
We sequenced 12S RNA mtDNA for the majority of the extant species of sloths and anteaters and compared our results with previous data obtained by our group using 16S RNA mtDNA in the same specimens and to GenBank sequences of the extinct giant sloth Mylodon. Our results suggest that pigmy-anteaters may be a case of the long-branch attraction phenomenon and also show the large genetic difference between the Amazonian and Atlantic forest three-toed sloths, contrasting with the small differences observed between the two non-Atlantic forest forms of sloths. These results have important implications for the taxonomy of sloths and anteaters and strongly suggest the placement of pigmy anteaters in their own family (Cyclopidae) and raising the taxonomic status of...

Occurrence of Cabassous tatouay (Cingulata, Dasypodidae) in Rio Grande do Sul and its potential distribution in southern Brazil Iheringia, Sér. Zool.
Oliveira,Stefan V. de; Corrêa,Luiz L. C.; Peters,Felipe B.; Mazim,Fábio D.; Garcias,Felipe M.; Santos,Janduhy P. dos; Kasper,Carlos B..
ABSTRACT Cabossous tatouay Desmarest, 1804 is considered a rare species in southern South America, and Rio Grande do Sul State, Brazil, records of the species are scarce and inaccurate. This study reports 40 localities for C. tatouay, and provides a map of the species' potential distribution using ecological niche modeling (ENM). The ENM indicated that in this region C. tatouay is associated with open grasslands, including the areas of "Pampas" and the open fields in the highlands of the Atlantic Forest. This study contributes to the information about the greater naked-tailed armadillo in southern Brazil, and provides data key to its future conservation.

Paleobiology of Pleistocene ground sloths (Xenarthra, Tardigrada): biomechanics, morphogeometry and ecomorphology applied to the masticatory apparatus Ameghiniana
Bargo,M. Susana; Vizcaíno,Sergio F..
The fossil xenarthrans include giant forms, the ground sloths (Tardigrada), characteristic of the mammal fauna of the Pleistocene of South America. Although most authors agree in considering them as herbivorous, these forms have not been studied in terms of detailed morpho-functional analyses of their masticatory apparatuses. The aim of this work is the study the masticatory apparatus of the large Pleistocene ground sloths Glossotherium robustum, Lestodon armatus, Mylodon darwini and Scelidotherium leptocephalum (Mylodontidae) applying biomecanichal and morphogeometrical methods, and to compare with the information obtained for Megatherium americanum (Megatheriidae). The results are integrated with recent ecomorphological analyses that include three...
