    Comportamento de fêmeas de elefantes asiáticos (Elephas maximus) e africanos (Loxodonta africana) em cativeiro: uma abordagem comparativa e sua importância para o bem-estar
    (2024-02-07) Cabral, Isabella Ribeiro de Melo; Schiel, Nicola; http://lattes.cnpq.br/5314455811830714; http://lattes.cnpq.br/7299148914808419
    For animals with complex lifestyles, large size, or a more developed cognitive system, such as elephants, promoting well-being in artificial environments becomes challenging. The study of animal behavior emerges as an essential tool to ensure the well-being of these species, providing management strategies tailored to their specific needs. In our research, we focused on the behavioral repertoire of captive female elephants, aiming to comparatively evaluate the behavioral repertoire of Asian (Elephas maximus) and African (Loxodonta africana) female elephants in these situations. To do this, we observed the behavior of both species through online cameras available at two zoos, each species in one zoo – Prague Zoo (Czech Republic) and Reid Park Zoo (USA) – with rigorous inclusion criteria to standardize the comparison, including: having female elephants, online cameras in the outdoor enclosures of the females, enclosures of similar sizes, similarity in reaction to the size of the elephant group, and group composition. We observed 9 behavioral categories, analyzing 6 (foraging, moving, stationary, self-maintenance, affiliative social, and agonistic social) over 13 days, with 50 hours of observation for each zoo. The Ad libitum method and the 5-minute scan sampling method were used for the elaboration of the ethogram and data collection, respectively. To verify if there were differences in the behavioral repertoire between the two species, we conducted the Mann-Whitney U test. Surprisingly, although the literature indicates differences in some behaviors between African and Asian species, such as foraging, stereotypy, and self-maintenance, we found no statistically significant differences between them in the analyzed categories, suggesting similar behaviors for both species in captivity. Our research suggests that, under the specific conditions of our participating zoos, Asian and African female elephants exhibited similar behaviors. It is essential to emphasize the importance of broader comparative studies, with comprehensive inclusion criteria, to obtain a holistic understanding of the specific behaviors of each species. This knowledge is crucial for the development of more effective care and management practices and strategies in zoo environments. The preservation of these magnificent species requires a continuous commitment to research and the development of adaptive strategies to ensure their well-being in zoo environments.

    A importância do enriquecimento ambiental para primatas em zoológicos
    (2022-05-26) Silva, Mayara de Freitas; Schiel, Nicola; Fuente Castellón, María Fernanda de la; http://lattes.cnpq.br/9523589239670783; http://lattes.cnpq.br/5314455811830714; http://lattes.cnpq.br/8631505182213359
    The use of environmental enrichment seeks to offer the animal in captivity conditions that stimulate its natural behavior, through techniques that modify its environment. Based on this, this research aimed to carry out a systematic review on the use of environmental enrichment as a tool to improve the well-being of primates in captivity, describing the types of enrichment, which are more effective and which groups present positive results from the use. of environmental enrichment. A total of 75 articles were evaluated between the years 1988 and 2021. Data were collected in two databases: Web of Science and Scopus, and the following information was extracted: article title, year of publication, place where it was carried out (institution and country), species, genus and family of the primate that received environmental enrichment, type of environmental enrichment applied, subtype of enrichment, the way in which environmental enrichment was employed, effect of environmental enrichment and how it was evaluated (behaviorally and/or physiologically). The results of this research show that in 63.76% of the times when environmental enrichment was applied, the effects were positive. The most used type of enrichment was social, but the one that most achieved positive effects was food enrichment. The most used method to assess these effects was through behavioral measures. Callitrichidae was the family that, proportionally, had the most positive effects on enrichment. And in relation to gender, Eulemur obtained more positive effects. From the results we can conclude that using environmental enrichment actually improves the well-being of primates in captivity, allowing them to perform natural behaviors and improve their well-being. Producing this type of research makes it possible to gather works on the use of enrichment in different zoos, with different families and genders, and to show the most used forms of enrichment, the successes (positive effects) and failures (negative effects). And in this way, build a database to help zoos apply environmental enrichment in their primates.

    The growing maintenance of animal specimensin captivity, kept in zoos and sanctuaries, and in Centers of Wild Animals Screening (CETAS), have raised more and more the necessity of newstudy approaches oncaptive animals, as means to reach a higher understanding about the behavioral biology of each species. As such, interventionist actions in spaces of captivity and the adequation of enrichment actions for the betterment of animals’ welfarebecome preponderant. Capuchin monkeys (Sapajus libidinosus) are animals native to Brasil, which exhibit a varied range of behaviors, both individual and social.At the same time, they are targets of capture fromboth the traffic of wild animals and scientific studies, precisely due to their behavioral variety and apparent inteligence. The Social Network Analysis comes as a tool in the study of social behaviors, becomingan increasingly more commonpracticein researches with primates worldwide. The Parque Estadual deDois Irmãos (PEDI)owns in its animal collectiona group of four individuals of the aforementioned species. As a way to understand the social relations between the individuals and the use of the captivity space by these animals, this project aimed for the statistical analysis of the behaviors of the subjects over space and time. A collection of data fulfilled through the counting of seconds of each activityand its specific place of happeningwas employed for the group analysis. Socially, the animals were evaluated via the production of sociograms, net structures that relate actors inside a group and the relations established between themselves. The chosen methodology was revealing in what concernsthe general aspects of the reproductive colony studied, but it also allowed a visualization of subtle characteristics between the animals and the space occupied by them. The obtaining of diversifieddata allowed for a bigger understanding of the social dynamics involved, and how further actions and researches canbe executed, bringing more pointed results in the analyses that have as aim the betterment of a captive individual’s welfare.
