“…The domestic dog (Canis familiaris, Linnaeus 1758) stands out among invasive mammalian predators, inducing drastic changes in communities and ecosystems around the world (Ritchie, Dickman, Letnic, & Vanak, 2014;Vanak, Dickman, Silva-Rodrı´guez, Butler, & Ritchie, 2014). They interact with native fauna at multiple levels (Vanak & Gompper, 2009), often resulting in negative impacts, such as predation, competition, surplus killing, pathogen spillover, and genetic introgression (Vanak & Gompper, 2009;Young, Olson, Reading, Amgalanbaatar, & Berger, 2011), contributing to the decline of biodiversity (Doherty, Dickman, Nimmo, & Ritchie, 2015;Doherty et al, 2017). The dog derived from Eurasian gray wolves (Canis lupus; Shannon et al, 2015), and since domestication, it has been subsidized and introduced worldwide as a ubiquitous commensal of humans (Vanak & Gompper, 2009.…”

Anthropogenic Disturbances Drive Domestic Dog Use of Atlantic Forest Protected Areas

Domestic dog is the most successful invasive mammalian predator species, and reducing its ecological impacts on wildlife is a central conservation goal globally. Free-ranging dogs can negatively interact with wildlife at multiple levels, posing issues for biodiversity conservation in tropical forests, especially in fragmented Atlantic Forest. To optimize future control programs, it is necessary to identify the main factors influencing their habitat use, particularly in natural reserves. We combined camera trapping data and occupancy models to characterize habitat use of dogs in six Atlantic Forest protected areas (134-36,000 ha). Our results show that dogs were more likely to use sites (É ! 0.90) having higher housing density (!4.00 houses/km 2 ) or higher proportion of croplands and pasture (!75%) relative to sites with no houses (É ¼ 0.23 AE 0.10) or lower proportion of croplands and pasture (É ¼ 0.34 AE 0.08). In addition, dogs had higher detection probability at camera locations on unpaved roads (p ¼ 0.33 AE 0.05) relative to off-road sites (p ¼ 0.18 AE 0.04), and in small protected areas with high housing density, that is, more disturbed sites, dogs had higher detection probabilities. Our findings indicate that the probability of dogs using a site within protected area is mainly driven by type and intensity of human activity in the surroundings. Given the urgent need to control free-ranging dogs within protected areas, we strongly recommend that managers target sites/areas within and near protected areas that have a rural housing density ! 4.00 houses/km 2 or higher proportion of croplands and pasture (!75%).

Underaddressed animal‐welfare issues in conservation

Much progress has been made toward assessing and improving animal welfare in conservation. However, several glaring knowledge gaps remain where animal‐welfare concerns exist but animal‐welfare studies have not been performed in politically sensitive contexts. Based on contemporary issues in Australia, we identified 4 topics that require more research: animal‐welfare oversight for operations designated as management (as opposed to research); animal‐welfare impacts of biological agents used to control invasive animals; welfare of animals hunted recreationally; and animal‐welfare impacts associated with indigenous wildlife use. Animal‐welfare science may be applied to these sensitive topics through simple quantitative studies (e.g., quantifying the frequency of adverse animal‐welfare events). Several such studies have effectively addressed animal‐welfare concerns in similarly contentious contexts, including feral camel (Camelus dromedarius) culling in Australia, recreational hunting in Scandinavia, and indigenous whale hunting in the United States. For discussions of animal welfare in conservation to be evidence‐based, courageous research is required in the 4 key areas we identified.

“…Also, dogs can be considered the most abundant carnivore in some areas of the Brazilian Atlantic Forest (Srbek-Araujo and Chiarello, 2008;Paschoal et al, 2016;Ribeiro et al, 2019). Dogs threaten wild animals due to predation, competition for territory, and disturbance (chasing or harassment) (Young et al, 2011;Silva-Rodríguez and Sieving, 2012;Lessa et al, 2016;Doherty et al, 2017). In addition, the risk of pathogen transmission from dogs to other animals, mainly mammals, is also an important problem.…”

Importantly, dogs are amplifier hosts of different pathogens (Dantas-Torres, 2007;Piranda et al, 2011;Szabó et al, 2013), which means that they can develop infection at sufficient levels to infect other species, such as vectors, increasing the disease transmission (Kilpatrick and Altizer, 2010;Labruna et al, 2011;Piranda et al, 2011).…”

The triad “dogs, conservation and zoonotic diseases” – An old and still neglected problem in Brazil

a b s t r a c tThe presence of domestic/free-ranging dogs in Brazilian protected areas and native vegetation fragments is an important problem, mainly because these animals pose a threat to wild species that live in such areas. In addition, dogs constantly circulate between wildlife environments and urban regions, acting as "bridges" in spillover events. Dogs are traditionally recognized as vectors of zoonoses, which are correct, but their roles as facilitating agents for the "jump" of pathogens from wild animals to humans (and vice versa) are sparsely debated. In this context, this work briefly describes the different roles of dogs in the dynamics and ecology of infectious diseases, using the Brazilian scenario as a study model.
