“…Despite the presence of species in these biomes there are records of small populations isolated in forest fragments (Moraes-Barros et al, 2010;Pedrosa and Castro, 2014;Andrade et al, 2020). Its presence in urban environments also is record (Manchester and Jorge, 2003;Manchester and Jorge, 2009;Silva et al, 2017;Pedrosa and Castro, 2018;Brandão et al, 2019, Andrade et al, 2020, in areas such as public squares and gardens (Pedrosa and Castro, 2018). Consequently, this is associated to the effects of the urbanization process, which modifies landscapes and fragments natural habitats (Pedrosa et al, 2016).…”

The brown-throated three-toed sloth Bradypus variegates Schinz, 1825 (Pilosa: Bradypodidae) is an arboreal mammal with wide distribution in the neotropical region. However, the presence of this species in urban environments has attracted attention due to the threats that this environment can offer to this species. In this context, the present study investigated the impacts over brown-throated three toed sloth’s population living in an urban area of Rio Tinto, Paraíba, as well as, analyze data from Wildlife Screening Center (Centro de Triagem de Animais Silvestres - CETAS) and the conservation units of Paraíba, to understanding threats and main factors that led individuals to these institutions. From 2011 to 2014 a sloth’s population was studied at João Pessoa Square in Rio Tinto. From 2010 to 2015 was analyzed data from CETAS, Guaribas Biological Reserve (GBR), Barra do Rio Mamanguape Environmental Protection Area (BRM-EPA) and Arruda Câmara Municipal Zoobotanical Park (AC-MZP).The place that most registered the receipt of sloths was CETAS (65.5%), followed by GBR (17.8%), AC-MZP (15%), and BRM-EPA (1.8%). Offspring were significantly more impacted than adults, because were recorded highest number of injured and dead individuals in CETAS. Offspring not survived also at João Pessoa Square in Rio Tinto (urban environment) until the reproductive phase, due to falls or the rejection of their mothers during parental care. The urbanized matrix causes changes in the parental care of the mother sloths, implying the early abandonment of their offspring. In addition, inadequate introductions of sloths at João Pessoa Square causing malnutrition in individuals due to the lack of insufficient nutrients available, and electric shocks caused by high voltage wires, resulting in death or limb amputation of adult sloths. To minimize these impacts, urban environments needs to be controlled, through tree pruning, prohibit the introductions of sloths and increase the diversity of plant species in this area.

“…A preguiça-comum (Bradypus variegatus, ordem Pilosa, superordem Xenarthra) é encontrada desde florestas da Nicarágua até a Mata Atlântica, no sul do Brasil [9]. Sua presença é comum em áreas antropizadas da Amazônia, e tem como principais ameaças atropelamentos, distribuições elétricas e caça para consumo humano [1,26,27]. Os espécimes resgatados, frequentemente enfermos, exigem atendimento clínico de emergência [17,22,24].…”

Background: The brown-throated sloth (Bradypus variegatus) occurs from the Nicaragua to Brazil. In brazilian amazonian, these animals are rescued with illnesses caused by anthropic actions. Emergencial treatment of sloths is complex because is a lack of specie-specific information allied to a particularly physiology. They have low metabolism and physiological parameters during resting time is 4-7 breaths/min, 40-100 heartbeats/min and temperature between 32-35ºC. They are also folivores, predisposing cases of dehydration and even hypovolemic shock. This study aimed to report the emergency treatment performed on a specimen of Bradypus variegatus affected by hypovolemic shock due to dehydration.Case: A male sloth weighing 2.7 kg was attended at the Veterinary Hospital-Wild Animals Sector of the Federal University of Pará (HVSAS-UFPA), victim of untreated hypovolemic shock due three days of forced eating with inadequate food, which resulted in dehydration, non-hemorrhagic hypovolemic shock, and severe apathy. Physiological parameters were 8 breaths/min, heart rate 90/min and rectal temperature of 33°C. Treatment begun with fluid therapy taking account of 10% of body dehydration (270 mL Ringer lactate, 8 mL vitamin complex and 2 mL glucose), for respiratory decompensation nebulization was conducted with epinephrine (0.5 mL/kg), and intramuscular administration of vitamin B complex (1 mg/kg), metoclopramide (0.2 mg/kg), ranitidine (0.5 mg/kg), and dexamethasone (0.3 mg/kg) to metabolic stimulation improvement. Physiological parameters were monitored every 10 min for the first 12 h of hospitalization. The management were gradually established as the clinical conditions were improved, including forced feeding, daily walks, and enclosure adapted for the minimal behavioral and biological requirements. After 14 days of intensive treatment, the animal was considered ready for release.Discussion: Treatment of critically ill and unnourishment patients requires prompt interventions. Animals with low metabolism potentially have reduced chances of success, therefore, a prompt establishment of viable airways and body temperature maintenance would allow the efficient drugs metabolization. Severe dehydration can lead to animal death by hypovolemic shock, as a consequence of low blood volume, diminish in blood pressure and in the amount of oxygen in body supply, so fluid replacement is essential, as well as stimulating respiratory compensation through bronchodilator drugs. Furthermore, metabolic stimulation is important in cases to prevent numbness, which is common in very weak sloths. The constant monitoring of physiological parameters since at first moment of hospitalization provided parameter to decide about particular needs adaptations during the animal recovery time. Such protocols described for the brown-throated sloth was absent in the literature. In conclusion, the therapeutic and management protocol implemented and adapted to a particular patience, as brown-throated sloth, resulted in a gradual clinical improvement and allowed to its return for the natural environment.

“…The B. variegatus were found in many cities cohabiting with humans as at Paraíba Federal University, where it lives in a density of approximately 2.26 animals/ha (Silva et al 2017). Within the city of Rio de Janeiro, Rio de Janeiro state, Brazil, it is currently found in the neighborhood of the Atlantic Forest Fiocruz Campus (CFMA-FIOCRUZ), often in hazard situations.…”

Management of Wild Sloths in an Anthropized Area at Atlantic Forest

Bradypus variegatus Schinz, 1825, is one of the four extant three-toed sloths. We report data on the management of free-living sloths in the Atlantic Forest Fiocruz Campus, Rio de Janeiro, Brazil. From 2013 to 2017, we have captured 23 sloths in hazard. The animals were microchipped and released in Pedra Branca State Park. Here we also report two recaptures, a mating observation and a case of electrocution, highlighting the importance of management for improving the knowledge in biology and conservation of this species.
