Simple SummaryFree-range sloths living in an urban environment are rare. In this study, opinions, attitudes, and interactions with a population of Bradypus variegatus were investigated through short, structured interviews and informal, opportunistic observations of people in the pubic square where the sloths live. A questionnaire was applied to people in the square where the sloths live. Opinions about population size differed greatly and younger people were concerned as to whether the square was an appropriate place for them. Some human-sloth interactions showed the consequences of a lack of biological knowledge. Sloths are strictly folivorous and are independent of human sources of food. Apparently, sloths are indifferent to humans. Despite the good intentions of people, there are many misconceptions about the behaviour and needs of sloths, which causes low wellbeing for the animals. These results demonstrate that actions in environmental education of the public could be beneficial for sloths.AbstractFree-range sloths living in an urban environment are rare. In this study, the opinions, attitudes, and interactions with a population of Bradypus variegatus were investigated through short, structured interviews of people in the pubic square where the sloths live, in addition to informal, opportunistic observations of human-sloth interactions. A questionnaire was applied to people in the square where the sloths reside, and informal, opportunistic observations of human-sloth interactions were made. 95% of respondents knew of the sloths’ existence in the square and 87.8% liked their presence. Opinions about population size differed greatly and younger people were concerned as to whether the square was an appropriate place for them. Some human-sloth interactions showed the consequences of a lack of biological knowledge. People initiated all sloth-human interactions. The fact that sloths are strictly folivorous has avoided interactions with humans and, consequently, mitigated any negative impacts of the human-animal interaction on their wellbeing. These results demonstrate that, while there is a harmonious relationship between people and sloths, actions in environmental education of the square’s public could be beneficial for the sloths.

Background and Aim: The brown-throated sloth (Bradypus variegatus) is widely distributed in three biomes: The Amazon, Atlantic Forest, and Caatinga. Some subpopulations are isolated in urban areas in Brazil, usually in squares and small woods. Due to the scarcity of reference values, an investigation was carried out on the hematology and blood biochemistry of brown-throated sloths from urban areas. Materials and Methods: Blood was collected by venipuncture in the femoral vein from 19 brown-throated sloths for hematological and biochemical analyses, living in two municipalities; Teófilo Otoni (TO) (Minas Gerais State) and Rio Tinto (RT) (Paraíba state), in the Atlantic Forest biome, Brazil. The samples were analyzed in specialized veterinary laboratories using automatic cell counters and slide fixation staining methods. Results: The two subpopulations of brown-throated sloths had no significant differences in most hematological values, with the exception of a higher leukocyte concentration (p<0.01) in the RT sub-population. The difference in leukocyte concentration suggests an idiosyncratic effect, as the animals were healthy and the stress of the capture was acute, not chronic. The concentrations of urea, creatinine, and alkaline phosphatase (ALP) were similar (p<0.05) in brown-throated sloths from TO and RT. Likewise, the liver enzyme concentrations (ALP, alanine transaminase [ALT], and aspartate transaminase [AST]) did not differ between the two subpopulations (p<0.05). Conclusion: Compared to another study, brown-throated sloths from TO and RT have higher plasma concentrations of ALT and ALP, suggestive of a hepatic overload. Hematological and blood biochemical findings of TO and RT can be used as clinical reference values for brown-throated sloths living in an urban environment.

Free-range sloths living in an urban environment is rare. In this study, human opinions, attitudes and interactions with a population of Bradypus variegatus in a public square were investigated. A questionnaire was applied to people in the square where the sloths reside, and informal, opportunistic observations of human-sloth interactions were made. 95% of respondents knew of the sloths&rsquo; existence in the square and 87.8% likes their presence. Opinions about population size differed greatly and younger people were concerned if the square was appropriate place for them. Some human-sloth interactions showed the consequence of lack of biological knowledge. People initiated all sloth-human interactions. The fact that sloths are strictly folivorous has limited their interactions with humans and consequently minimised negative impact of the human-animal interaction on their wellbeing. These results demonstrate that while there is a harmonious relationship between people and sloths, actions in environmental education of the square&rsquo;s public could be beneficial for the sloths.

The teaching-learning process becomes more attractive when practical classes are used as part of methodological tools. Aiming (i) to stimulate the interest of high school students in the microbiological world and (ii) to provide didactic experience for microbiology graduate students, practical classes were undertaken. These classes were carried out during 2016 and 2017 using the infrastructure at Universidade Federal de Viçosa. Briefly, laboratory classes were prepared and taught by microbiology graduate students and an evaluation questionnaire was answered by the participants after the classes. Approximately 95% of high school students, from both years, evaluated the experience outside the school routine as very good and good; in detail, 90.09% (2016) and 100% (2017) of graduate students evaluated this experience as very good and good. The relationship between high school and graduate students also increased the curiosity of the former regarding the university environment. Accordingly, information retention regarding the ‘microbiology world’ was verified after 1 year and the students were able to remember important terms related to the microbiology class. In addition, this work allowed graduate and high school students to build a closer relationship and created an excellent teaching-learning strategy for both.
