“…Brown howler monkeys, alike their congenerics, are known for their high resilience to habitat disturbance, which has been associated with their highly flexible folivorousfrugivorous diet, including the exploitation of cultivated foods (Dias and Rangel-Negrín, 2015;Bicca-Marques, 2016, 2017), and their home ranges often <15 ha. Brown howler populations in peri-urban areas in southern Brazil are commonly confined to small (<10 ha) private forest fragments (Printes et al, 2010;Chaves and Bicca-Marques, 2013;Corrêa et al, 2018). These discrete subpopulations may interact in patchy metapopulations and persist longer than those more isolated in the landscape.…”

“…This resilience has been associated with their highly flexible folivorous-frugivorous diet, including the exploitation of cultivated foods in gardens and orchards (Dias and Rangel-Negrín, 2015; Chaves and Bicca-Marques, 2016, 2017), and their home ranges often <15 ha. Brown howler monkey populations in peri-urban areas in southern Brazil are commonly confined to small (<10 ha) private forest fragments (Printes et al, 2010; Chaves and Bicca-Marques, 2013; Corrêa et al, 2018). These discrete subpopulations may interact as metapopulations and may therefore play an important role in the conservation of this threatened species that is also highly susceptible to outbreaks of yellow fever (Almeida et al, 2012; Bicca-Marques et al, 2017; Buss et al, 2019).…”

Urbanization and deforestation impose severe challenges to wildlife, particularly for forest-living vertebrates. Understanding how the peri-urban matrix impacts their survival is critical for designing strategies to promote their conservation. We investigated the threats faced by brown howler monkeys (Alouatta guariba clamitans) in peri-urban regions of Rio Grande do Sul (RS) and Santa Catarina (SC) states, southern Brazil, by compiling conflicts reported over more than two decades. We assessed the major conflicts, their distribution among age-sex classes, and the predictors of conflict-related mortality using GLMMs. After 20+ years of monitoring, we compiled 540 conflicts (RS=248 and SC=292). Electrocution in power lines was the most frequent cause of death or injury (37%), followed by dog attack (34%), run over (17%), and human mistreatment (12%). The occurrence of lethal injuries ranged from 5% to 69% depending on the type of conflict and state. The overall post-conflict mortality was 56%. Adult males and females were the major victims in both states. The minimal adequate GLMM explained 83% of the variation in conflict-related mortality. State, conflict type, and age-sex class were the main predictors of mortality. Overall, mortality was lower in SC and after human mistreatment, and higher among adult females than in the other classes. We found that the survival of brown howlers in the forest-urban interface is constrained by both the urban infrastructure and the growing interactions with humans and domestic and stray dogs. We propose the placement of aerial bridges, road signs and speed bumps in areas of frequent animal crossing, the sterilization of stray dogs, and the sensitization of local inhabitants on the importance of respecting and protecting wildlife to reduce their conflicts with humans and domestic animals in the forest-urban interface.Graphical AbstractHIGHLIGHTSWe investigated the threats faced by brown howler monkeys in peri-urban regions of southern Brazil.After 20+ years of monitoring, we compiled 540 conflicts between monkeys and humans in the two study regions.The main conflicts were electrocution (37%), dog attack (34%), run over (17%), and mistreatment (12%).Lethal injuries ranged from 5% to 69% depending on conflict type.State, conflict type, and age-sex class explained 83% of the variation in conflict-related mortality.

“…The first, the Programa Macacos Urbanos in Porto Alegre, Brazil, lodged a legal complaint against the state power company, citing primate electrocutions as an environmental crime. The judgment was entered in favor of the plaintiff and obliged the company to install approximately US$30,000 worth of insulation materials on the grid (Printes et al, 2010).…”

Infrastructure Development and Ape Conservation

Infrastructure development in Africa and Asia is expanding at breakneck speed, largely in biodiversity-rich developing nations. The trend reflects governments' efforts to promote economic growth in response to increasing populations, rising consumption rates and persistent inequalities. Large-scale infrastructure development is regularly touted as a way to meet the growing demand for energy, transport and food-and as a key to poverty alleviation. In practice, however, road networks, hydropower dams and "development corridors" tend to have adverse effects on local populations, natural habitats and biodiversity. Such projects typically weaken the capacity of ecosystems to maintain ecological functions on which wildlife and human communities depend, particularly in the face of climate change.This volume-State of the Apes: Infrastructure Development and Ape Conservationpresents original research and analysis, topical case studies and emerging tools and methods to inform debate, practice and policy with the aim of preventing and mitigating the harmful impacts of infrastructure projects on biodiversity. Using apes as a proxy for wildlife and ecosystems themselves, it identifies opportunities for reconciling economic and social development with environmental stewardship. This title is available as an open access eBook via Cambridge Core and at www.stateof theapes.com.

“…The 25 ha squares totally or partially covered with native forests -which are mainly influenced by the Atlantic forest in a subtropical climate -constituted the sample units. Each unit was visited by two or more researchers, for at least two hours, to check for the occurrence of howlers by either direct sighting of individuals or the presence of feces (BUSS, 1996, PRINTES et al, 2010.…”

“…Efforts to return a few individuals of non-threatened species to the wild are not usually considered conservationist measures, nor are measures focused on individual members of endangered species (SOORAE & BAKER, 2002). Nevertheless, because howlers are considered locally and regionally threatened and conflicts with humans in Porto Alegre and vicinity are frequent (PRINTES, 1999;PRINTES et al, 2010;LOKSCHIN et al, 2007), the PMU considered that it was necessary to manage individual howler monkeys.…”

ABSTRACT. Human interventions in natural environments are the main cause of biodiversity loss worldwide. The situation is not different in southern Brazil, home of five primate species. Although some earlier studies exist, studies on the primates of this region began to be consistently carried out in the 1980s and have continued since then. In addition to important initiatives to study and protect the highly endangered Leontopithecus caissara Lorrini & Persson, 1990 and Brachyteles arachnoides E. Geoffroy, 1806, other species, including locally threatened ones, have been the focus of research, management, and protection initiatives. Since 1993, the urban monkeys program (PMU, Programa Macacos Urbanos) has surveyed the distribution and assessed threats to populations of Alouatta guariba clamitans (Cabrera, 1940) in Porto Alegre and vicinity. PMU has developed conservation strategies on four fronts: (1) scientific research on biology and ecology, providing basic knowledge to support all other activities of the group; (2) conservation education, which emphasizes educational presentations and long-term projects in schools near howler populations, based on the flagship species approach; (3) management, analyzing conflicts involving howlers and human communities, focusing on mitigating these problems and on appropriate relocation of injured or at-risk individuals; and finally, (4) Public Policies aimed at reducing and/or preventing the impact of urban expansion, contributing to create protected areas and to strengthen environmental laws. These different approaches have contributed to protect howler monkey populations over the short term, indicating that working collectively and acting on diversified and interrelated fronts are essential to achieve conservation goals. The synergistic results of these approaches and their relationship to the prospects for primatology in southern Brazil are presented in this review.

Primatologia no sul do Brasil: uma abordagem transdisciplinar para a conservação do bugio-ruivo Alouatta guariba clamitans (Primates, Atelidae) na região de Porto Alegre, Brasil.
