Abstract As urbanisation continues to reduce the available habitat for wildlife some species, such as the black-and-gold howler monkey (Alouatta caraya) in Pilar, southwest Paraguay, are making their homes in anthropogenic environments. Understanding an animal's home range is an important first step to understanding its ecological needs, an essential requirement for robust conservation plans. In this study we determined the home ranges and core areas of five groups of urban dwelling A. caraya using Minimum Convex Polygon (MCP) and Kernel Density Estimation (KDE) Analysis. We used a Spearman’s Correlation to explore the relationship between home range size and group size. All five groups had home ranges of less than 10 ha and used core areas of less than 1ha. Group size had no significant relationship to home range size. We provide the first estimates of home range for A. caraya in an urban environment in Paraguay. Though the home ranges of the urban A. caraya in Pilar, Paraguay fall at the smaller end of the spectrum of range sizes in Alouatta they are not abnormal for a species in this genus.

O presente trabalho teve por objetivo avaliar como o bugio (Alouatta caraya) está inserido no contexto do turismo de observação de vida silvestre no Pantanal Sul e seu reconhecimento enquanto espécie-bandeira, além de pautar recomendações para o ecoturismo na região pantaneira. A área de estudo contempla a região do Pantanal sul-mato-grossense. Para a coleta de dados foi aplicado um formulário semiestruturado aos turistas que visitaram o Pantanal Sul e moradores locais da região do Passo do Lontra (Pantanal do Miranda) e da Curva do Leque (Pantanal do Abobral/Nhecolândia). Para a aplicação dos formulários foram realizadas entrevistas in loco e via plataforma digital online. Para identificação do bugio enquanto espécie-bandeira foram utilizados critérios conforme literatura científica. Foram entrevistadas 106 pessoas, entre turistas e residentes da comunidade local. De acordo com os critérios adotados, pode-se dizer que A. caraya reúne vários atributos que a tornam espécie de alto valor para a conservação sistêmica do Pantanal. A mesma pode ser considerada uma das espécies-bandeira do Pantanal, emblemática para o ecoturismo e uso educacional, contribuindo para a formação de uma consciência socioambiental de proteção à biodiversidade em sua totalidade.

Abstract Objective: In this study, we investigated the occurrence of papillomavirus (PV) infection in non-human primates (NHP, Platyrrhine) of northeastern Argentina by using broad-spectrum PCR primers at the L1 gene. In addition, we conducted a phylogenetic and coalescence analysis of viral sequences to explore their evolutionary history and evaluate the co-speciation hypothesis in the context of primate evolution. Methods: We obtained samples of 57 individuals from wild and captive populations of Alouatta caraya, Sapajus nigritus and Sapajus cay. We assessed PV infection by PCR amplification with the CUT primer system and sequencing of 337 bp (112 amino acids) of the L1 protein. The viral sequences were analyzed by phylogenetic and Bayesian coalescence methods to estimate the age of the most common recent ancestor (tMCRA) with BEAST, v1.4.8 software. We evaluated viral/host tree congruence with TreeMap v3.0. Results: We identified two novel putative PV sequences of the genus Gamma- PV in Sapajus sp and Alouatta caraya (SPV1 and AcPV1, respectively). The tMRCA of SPV1 was estimated at 11,941,682 years before present (ybp) and that of AcPV1 at 46,638,071 ybp, both predating the coalescence times of their hosts: 6.4 million years (MYA) and 6.8 MYA, respectively. Based on the comparison of primate and viral phylogenies, we could not reject the null hypothesis that the PV tree is no more congruent with the host tree than a random tree would be (P>0.05). Thus, a model of virus-host coevolution was rejected. Conclusion: This study presents the first report of PV infection in Platyrrhine species from Argentina, expands the range of described hosts for these viruses, and proposes new scenarios for their origin and dispersal.

The expansion of human populations associated with urbanization results in extensive modification of natural habitats. While many species cannot persist in these highly modified environments, some species adopt new strategies, which contribute to their survival. Several primate species have persisted in altered habitats, including members of the genus <i>Alouatta</i>. To improve our understanding of this interplay, we compared glucocorticoid (GCC) levels in male and female black and gold howler monkeys (<i>Alouatta caraya</i>) in urban and rural areas in northeastern Argentina. Fecal samples (<i>n</i> = 60) were collected from adults and hormone extracts were analyzed by enzyme immunoassays (EIA). Monkeys living in urban areas (females: 109.15 ± 18.83; males: 106.15 ± 10.48) had lower GCC<i></i>levels than monkeys living in rural areas (females: 152.01 ± 19.50; males:139,82 ± 10.85). Interestingly, males living in urban areas had lower GCC levels compared to those living in rural areas, whereas no differences were observed in GCC levels between females living in urban and rural areas. While these results suggest that urban areas may provide a release from intergroup competition for male howler monkeys, future work is needed to better understand the dynamics of this association to best inform management and conservation of this vulnerable species.

<p>Este proyecto es una tarea de extensión desde el ámbito de la investigación de monos aulladores negros y dorados (Alouatta caraya) y de zorros (Cerdocyon thous, Lycalopex gymnocercus) que habitan en las zonas de interfase urbano-rural de la Estación Biológica Corrientes (EBCo, CCT, CONICET) y un proyecto de UN- NE+SALUD 2019. Los objetivos generales incluyeron proponer acciones para la detección temprana de ciertas enfermedades en la comunidad desde la participación ciudadana. Se efectuaron una serie de encuentros con ciudadanos/as de las localidades de la ciudad de Corrientes y Mburucuyá sobre el conocimiento de la ecología y epidemiología de estas especies centinelas. La meta es impulsar una red integrada por ciudadanos/as locales motivados/as por la búsqueda personal y colectiva de soluciones a problemáticas ambientales y epidemiológicas En total se llevaron a cabo tres presentaciones del proyecto a la que asistieron un total de 120 personas, y ocho talleres con la participación de 62 personas entre ambas localidades, que consistieron en salidas de campo en áreas protegidas y rurales, práctica de análisis coproparasitológicos y elaboración de proyectos de acción. La red de "Centinelas en acción" en la región noreste de Argentina actuará como nodo de comunicación entre los profesionales, los participantes capacitados y los actores de zonas urbanas, periurbanas o rurales que coexistan y se relacionen con estas especies centinelas. Es de interés promover la sensibilización de la comunidad sobre estas temáticas de Salud pública y de Salud de los Ecosistemas, desde una actividad investigativa y de ciencia ciudadana, generando concientización y la implementa- ción de acciones para asegurar la conservación de estas especies a largo plazo.<br /><br /><br /></p>
