“…Pair formation was recorded in 10 occasions and some individuals were paired with different dogs in some occasions. Most pairs dogs can be preyed upon by native species (Butler et al, 2004). Farrel et al (2000), for example, found remains of domestic dogs in puma scats in Venezuela.…”

“…Disease transmission seems, however, to be the most important disturbance effect in many continental countries (Cleaveland et al, 2000;Frolich et al, 2000;Anderson et al, 2003;Hammer et al, 2004). Past studies have explored the presence of domestic dogs in wild areas or their impact on wild species (Herranz et al, 2002;Butler et al, 2004;Manor and Saltz, 2004;Anderson et al, 2006), however few studies have been conducted in Neotropical forests. These include predation on native species (Kruuk and Snell, 1981;Barnett and Rudd, 1983), potential disease transmission (Ryan et al, 2003;Fiorello et al, 2004;Deem and Emmons, 2005;McFadden et al, 2005;Fiorello et al, 2006), and social biology of free-roaming dogs (Daniels and Bekoff, 1989;Fielding and Mather, 2001).…”

Presence of exotic species in forest remnants is a major concern for the conservation of wild species, not only on islands, where potential impact is higher. Although the problem is widespread and increasing, there are few studies on Neotropical forests. Here we quantify the occurrence of domestic dogs (Canis lupus familiaris) in an Atlantic forest reserve in south-eastern Brazil (Santa Lúcia Biological Station -SLBS). Throughout two years of monitoring with camera traps (2,142 camera-days), 25 records of 16 individual dogs were obtained in the interior of SLBS, making dogs the fourth most frequently recorded species of mammals in general and the first-ranking among Carnivora, ahead of the ocelot and puma, the top two terrestrial predators present in SLBS. Dogs entered the forest year round, in almost half of the sampled months (48%), and predominantly during daytime (89%). They were detected in various trails inside the reserve, but mostly in areas nearest to the reserve's border (<200 m from the edge). Record rates of domestic dogs did not correlate significantly with climate variables, with frequency of mammal records and richness in general, or with any particular mammal species (Spearman rank correlation, p > 0.05 in all cases), suggesting an erratic, nonseasonal pattern of entrance in the reserve. Data indicate that domestic dogs can be abundant and frequent visitors to little disturbed Atlantic forest reserves even when these are located in regions of low density of human population. The potential impact to native fauna is discussed.Keywords: Atlantic forest, camera traps, Canis lupus familiaris, domestic dogs, exotic species.Cães-domésticos em remanescentes de Mata Atlântica no sudeste do Brasil: padrões de entrada e de ocupação obtidos a partir de armadilhas fotográficas Resumo A presença de espécies exóticas em remanescentes florestais é um dos maiores problemas para a conservação de táxons silvestres, não apenas em ilhas, onde o impacto potencial do contato entre os grupos citados revela-se mais significativo. Apesar deste problema ser amplo e crescente, poucos são os estudos desenvolvidos em florestas Neotropicais. Neste sentido, o presente estudo objetivou caracterizar a presença de cães-domésticos (Canis lupus familiaris) em uma reserva de Mata Atlântica localizada no Sudeste do Brasil (Estação Biológica de Santa Lúcia -EBSL). A partir de dois anos de monitoramento com armadilhas fotográficas (2.142 câmeras-dia), foram obtidos 25 registros de 16 indivíduos no interior da EBSL. Com relação ao número de registros obtidos, o cão-doméstico foi a quarta espécie mais registrada, considerando a mastofauna de maneira geral, e a primeira entre os Carnivora, estando à frente da jaguatirica e da onça-parda, os dois principais predadores terrestres presentes na EBSL. Os cães-domésticos entraram na reserva durante todo o ano, apresentando registros em quase metade dos meses de amostragem (48%), predominantemente ao longo do dia (89%). Os espécimes foram detectados em várias trilhas no interior da EBSL, ...

“…Dogs can prey upon other mammals, mainly C. paca, M. gouazoubira, and D. azarae. Several authors showed that the presence of dogs in forests can lead to the decline of native species, causing a negative environmental impact (Horowitz, 1992;Lacerda et al, 2009;Oliveira and Cavalcanti, 2002;Butler et al, 2004;Anderson et al, 2006;Galetti and Sazima, 2006;Srbek-Araújo and Chiarello, 2008). Torres and Prado (2010) concluded that by increasing the awareness of residents in the surroundings of a forest is crucial to reduce the impacts of domestic dogs.…”

Sampling allows assessing the impact of human activities on mammal communities. It is also possible to assess the accuracy of different sampling methods, especially when the sampling effort is similar. The present study aimed at comparing two mammalian surveys carried out over a three-year interval, in terms of sampling effort, capture success, abundance of domestic dogs, impact of human activities, and relative biomass using camera traps, in the Serra do Japi Biological Reserve and surroundings, located in Jundiaí, state of São Paulo, southeastern Brazil. The total richness recorded was 13 species, one domestic and 12 wild mammals. Sampling effort in both surveys was similar, but capture success and number of captures differed. The abundance of wild mammals and dogs did also differ between surveys. There was a highly significant correlation between abundance of wild mammals and capture effort for the survey performed in 2006/2007, but not for the survey performed in 2009/2010. The difference between samples may be related to human disturbance, since the number of domestic mammals photographed was higher in the second survey, three years after the first survey. Despite being a reserve, the area is still under pressure from urbanization, biological invasion, environmental degradation, and hunting, which may reduce the abundance of wild mammals.Keywords: survey, diversity, domestic animals, methods, nature reserves.Comparação entre duas amostragens de mamíferos feitas com armadilhas fotográficas no sudeste do Brasil, com foco na abundância de mamíferos silvestres e cães domésticos Resumo Uma das formas de avaliar o impacto das atividades humanas nas comunidades de mamíferos e ter maior conhecimento e acurácia sobre o método utilizado é realizar amostragens, proporcionando a comparação do método, principalmente quando o esforço amostral é semelhante. O presente estudo visou a comparar dois levantamentos de mamíferos realizados na mesma área com três anos de intervalo, quanto aos seguintes aspectos: esforço amostral, sucesso de captura, abundância de cães domésticos, presença de atividades humanas e biomassa relativa das espécies. A riqueza total obtida nos dois períodos de amostragem foi de 13 espécies, sendo 12 espécies selvagens e uma de animal doméstico. O esforço de amostragem para as duas pesquisas foi semelhante, porém o sucesso de captura foi diferente, quando comparados entre si. A abundância de mamíferos selvagens e cães também mostrou diferenças entre os dois períodos. A correlação entre a abundância de mamíferos selvagens e o esforço de captura provou ser altamente significativa para a amostragem realizada em 2006/2007, mas não foi significativa para a realizada em 2009/2010. A diferença entre as amostras pode estar ligada à perturbação humana nesse ambiente, já que o número de animais domésticos fotografados foi maior após três anos de amostragem. Apesar de ser uma área de conservação, também está sujeita a pressões, como especulação imobiliária, invasões, destruição e caça, o que pode estar dim...

“…Diseases of domestic animals threaten wildlife. For example, domestic dogs are carriers of canid diseases transmissible to wild carnivores (Butler et al 2004) and were partly responsible for extinction of the African wild dog Lycaon pictus and decimation of lions Panthera leo in areas of the Serengeti (see Woodroffe 1999). Additionally, livestock can transmit animal diseases (e.g.…”

Protected areas cover 12% of terrestrial sub-Saharan Africa. However, given the inherent inadequacies of these protected areas to cater for all species in conjunction with the effects of climate change and human pressures on protected areas, the future of biodiversity depends heavily on the 88% of land that is unprotected. The study of biodiversity patterns and the processes that maintain them in human-modified landscapes can provide a valuable evidence base to support science-based policy-making that seeks to make land outside of protected areas as amenable as possible for biodiversity persistence. We discuss the literature on biodiversity in 2 sub-Saharan Africa"s human-modified landscapes as it relates to four broad ecosystem categorizations (i.e. rangelands, tropical forest, the Cape Floristic Region, and the urban and rural built environment) within which we expect similar patterns of biodiversity persistence in relation to specific human land uses and land management actions. Available research demonstrates the potential contribution of biodiversity conservation in human-modified landscapes within all four ecosystem types and goes some way towards providing general conclusions that could support policy-making. Nonetheless, conservation success in humanmodified landscapes is hampered by constraints requiring further scientific investment, e.g. deficiencies in the available research, uncertainties regarding implementation strategies, and difficulties of coexisting with biodiversity. However, information currently available can and should support efforts at individual, community, provincial, national, and international levels to support biodiversity conservation in human-modified landscapes.
