“…In fact, in both environments (and not only in agroforests) visits by domestic dogs seem to be associated with the period of human activity, concentrating during the day, as observed in other studies [e.g. 44,46], and on working days during the week. This suggests that the control of invasion rests on conscious efforts by workers and local residents to limit the movements of their dogs -by keeping them home instead of allowing or stimulating dogs to follow them into agroforests.…”

Although the value of agroforests for biodiversity conservation has been frequently highlighted, little is known about the susceptibility of this production system to biological invasions. Drawing on a camera-trap dataset obtained in 39 sites in an agroforestry mosaic in southern Bahia, Brazil, we investigated whether the conversion of native forests into agroforests and management intensification in agroforests favor the invasion by the most common carnivore worldwide, the domestic dog. We also examined whether domestic dog invasion is more associated with human activity in agroforests than in native forests. While the number of invading dogs was higher in agroforests than in native forests (11 compared to 7 dogs per site), management intensification in agroforests led to a higher mean number of visits per dog. In both habitats (not only agroforests) visits by domestic dogs tended to be concentrated on times of the day (around midday) and days of the week (Monday to Saturday) when there is greater human activity. Despite being permeable to native species, agroforests may act as sink or trap areas given their higher susceptibility to invasion, potentially limiting the value of this production system for biodiversity conservation. Moreover, local management intensification, which has been expanding worldwide, increases the intensity of such invasions, further decreasing the value of agroforests. The value of agroforestry mosaics for conservation thus depends on the management of invasive species and at least in the case of dogs, one of the most common and widely distributed invasive species, this management should focus on the habits and behavior of humans.Keywords: alien species; Atlantic forest; Canis familiaris; land-sharing strategies; wildlife-friendly agriculture. ResumoEmbora o valor das agroflorestas para a conservação da biodiversidade tenha sido freqüentemente destacado, pouco se sabe sobre a suscetibilidade deste sistema de produção à invasão biológica. A partir de um banco de dados obtido através de amostragem com armadilhas fotográficas em 39 sítios de um mosaico agroflorestal no Sul da Bahia, Brasil, nós investigamos se a conversão de florestas nativas em agroflorestas e a intensificação do manejo das agroflorestas favorecem a invasão pelo carnívoro mais comum no mundo, o cachorro doméstico. Nós também verificamos se a invasão por cachorros domésticos está mais associada à atividade humana nas agroflorestas do que nas florestas nativas. Enquanto o número de cães invasores foi maior nas agroflorestas do que nas florestas nativas (11 contra 7 cachorros por sítio), a intensificação do manejo das agroflorestas levou a um maior número médio de visitas por cachorro. Nos dois habitats (não apenas nas agroflorestas), as visitas de cachorros tenderam a se concentrar nos horários do dia (próximo ao meio dia) e nos dias da semana (segunda a sábado) em que existe maior atividade humana. Embora permeáveis às espécies nativas, as agroflorestas podem atuar como áreas sumidouro dada sua maior suscetibilidad...

“…Even recently these species are not cited as targets of poaching in NBSP (Vilela & Guedes 2009). We believe that regional fragmentation and historical poaching is the reason for species local extinction (Reyna-Hurtado et al 2009, Jácomo et al 2013), but also the presence of domestic dogs is worrying because they are responsible for loss of biodiversity via competition, predation and disease (Paschoal et al 2012, Hughes & Macdonald 2013. Domestic dogs need to be eradicated from protected areas.…”

Abstract. Nova Baden State Park (NBSP) is located in theBrazilian Atlantic Forest which is a biodiversity hotspot and priority for conservation. Our aim is to provide a list of large and medium-sized mammal species recorded in NBSP. We made a camera trap survey and opportunistic observations from December 2014 to September 2015, and searched the grey literature. We recorded 12 large and medium-sized mammals in our survey and 11 more species listed in grey literature. The 23 species registered for NBSP belong to eight orders (Carnivora, Primates, Rodents, Cingulata, Pilosa, Didephimorphia, Lagomorpha and Artiodactyla), including threatened species at local, national and global levels. With an important mammal biodiversity, we concluded that avoidance of poaching and the control of domestic dogs need to be priorities for biodiversity conservation of NBSP, with a political management that includes the local community in Park activities.

Gastrointestinal parasites of maned wolf (Chrysocyon brachyurus, Illiger 1815) in a suburban area in southeastern Brazil

We examined 42 maned wolf scats in an unprotected and disturbed area of Cerrado in southeastern Brazil. We identified six helminth endoparasite taxa, being Phylum Acantocephala and Family Trichuridae the most prevalent. The high prevalence of the Family Ancylostomatidae indicates a possible transmission via domestic dogs, which are abundant in the study area. Nevertheless, our results indicate that the endoparasite species found are not different from those observed in protected or least disturbed areas, suggesting a high resilience of maned wolf and their parasites to human impacts, or a common scenario of disease transmission from domestic dogs to wild canid whether in protected or unprotected areas of southeastern Brazil.Keywords: Chrysocyon brachyurus, impacted area, parasites, scat analysis. Parasitas gastrointestinais de lobo-guará (Chrysocyon brachyurus,Illiger 1815) em uma área suburbana no sudeste do Brasil ResumoForam examinadas 42 fezes de lobo-guará em uma área desprotegida e perturbada do Cerrado no sudeste do Brasil. Nós identificamos seis táxons de helmintos endoparasitas, sendo o Filo Acantocephala e a Família Trichuridae os mais prevalentes. A alta prevalência da Família Ancylostomatidae indica uma possível transmissão por cães domésticos, que são abundantes na área de estudo. No entanto, nossos resultados indicam que as espécies de endoparasitas encontradas não são diferentes daquelas observadas em áreas protegidas ou menos perturbadas, o que sugere uma alta resiliência do lobo-guará e seus parasitas aos impactos humanos ou um cenário comum de transmissão de doenças de cães domésticos para um canídeo selvagem, seja em áreas protegidas ou desprotegidas do sudeste do Brasil.Palavras-chave: Chrysocyon brachyurus, área impactada, parasitas, análise fecal.
