Human and domestic animal populations as a potential threat to wild carnivore conservation in a fragmented landscape from the Eastern Brazilian Amazon

Domestic dogs in rural area of fragmented Atlantic Forest: potential threats to wild animals

“…Due to vaccine failures, dogs are suspected of transmitting rabies in some countryside's around the world (CARNIELI et al, 2009). In recent years few scientifi c studies were conducted in rural areas of Brazil regarding dog vaccination against distemper, parvovirusis and leptospirosis (WHITEMAN et al, 2007). The contact or proximity of wild animals with unvaccinated dogs suggests a high risk of infectious diseases transmission.…”

Domestic dogs in a fragmented landscape in the Brazilian Atlantic Forest: abundance, habitat use and caring by owners

“…According to Lacerda et al (2009) the maned wolf (Chrysocyon brachyurus Illiger) and the giant anteater (Myrmecophaga tridactyla Linnaeus) seem to avoid areas with dog tracks. In a fragmented landscape in the Amazon, the presence of domestic dogs is related to disease transmission for wild carnivores (Whiteman et al, 2007). In the Brazilian Atlantic Forest, dogs have also been reported to threaten wildlife.…”

“…In megadiverse areas like Africa and Latin America, domestic dogs (Canis lupus familiaris Linnaeus) pose serious risks to native species as vectors of diseases, predators and competitors (Butler and Bingham, 2000;Butler and du Toit, 2002;Fiorello et al, 2006;Galetti and Sazima, 2006;Oliveira et al, 2008;Whiteman et al, 2007). Such threats are more important in rural and periurban areas of tropical regions, where households typically own dogs that are allowed to roam and breed freely (Butler and Bingham, 2000;Butler and du Toit, 2002;Kitala et al, Therefore, this work presents basic data about abundance, caring and behaviour of domestic dogs in a fragmented landscape in the Brazilian Atlantic Forest, which can be used to evaluate and mitigate the impacts of this exotic species in this Biodiversity Hotspot.…”

Determinación de parásitos gastrointestinales en carnívoros en el centro de México

“…La acelerada urbanización y la fragmentación del hábitat han incrementado la interacción entre animales domésti-cos y silvestres lo que puede resultar en el intercambio de ecto y endoparásitos (Whiteman 2007). Además, ésta es fortalecida por hábitos humanos como la incorrecta deposición de los desechos o deposición intencional de alimento para animales silvestres (Bradle & Altizer 2007); sin conocer los daños que puede causar a la salud pública y a la fauna silvestre y doméstica (Reperant et al 2007).…”

“…La variación en la prevalencia parasitaria y en las especies parásitas previamente reportadas y en las encontradas para los tres carnívoros puede deberse a cambios en los factores climáticos, ya que se han registrado cambios en la carga parasitaria de acuerdo con la estación (Hernández-Camacho et al 2011). Asimismo, el número de asentamientos humanos y su cercanía a la zona de estudio incrementa la posibilidad de interacciones con animales domésticos; los cuales son considerados transmisores de una gran variedad de parásitos (Whiteman 2007).…”
