“…During the time of the study, C. l. familiaris showed high activity patterns that clearly generate interference with activity patterns of C.thous, probably causing alterations in its behaviour. This idea is supported by Lenth et al (2008), who detected levels of alteration in activity patterns caused by domestic dogs over species like grey foxes (Urocyon cinereoargenteus). Sime (1999) warns about the negative effect of C. l. familiaris on foxes in general and Ordeñana et al (2010) found that where human activity is http://ciencias.javeriana.edu.co/investigacion/universitas-scientiarum concentrated, other carnivores were displaced.…”

“…In the case of species such as C. thous and canids in general, Lenth et al (2008), Torres & Prado (2010), as well as Abi-Said & Amr (2012) agree that these species change their habits from diurnal to nocturnal as a result of pressures generated by human settlements and the introduction of exotic species. Both of these pressures exist in the SFFOQ; there is the presence of human settlements, and the confirmed presence of exotic species such as C. l. familiaris, which had crepuscular and nocturnal habits, causing interference or maybe competition for resources with C. thous.…”

“…Bogotá Additionally, monitoring mammal diversity and activity patterns is important due to the relationships of these animals with anthropogenic dynamics, as supported by evidence outside and inside protected areas affected by human presence (Ordeñana et al 2010, Lira-Torres & Briones-Salas 2012, Gonthier & Castañeda 2013, Lynam et al 2013, in agriculture lands near forests (Cove et al 2013), in interfaces between rural and urban areas (Abi Said & Amr 2012, Saito & Koike 2013, as well as in relation with the presence of exotic species (Ordeñana et al 2010, Lenth et al 2008. Therefore, monitoring species community diversity and activity patterns are fundamental aspects when evaluating species vulnerability within a protected area.…”

Between the second semester of 2009 and the first semester of 2011, camera traps were set up in conserved and disturbed habitats in the Otún Quimbaya Flora and Fauna Sanctuary. From a sampling effort of 2,066 camera-days, 673 photographs of 157 independent events were obtained for eight species of wild mammals and a domestic one. Their activity patterns were mainly nocturnal even for those species reported as diurnal. The impact of human interference and exotic species was evident for two species: Tapirus pinchaque and Cerdocyon thous. The former was observed below its altitudinal range with activity patterns mainly crepuscular and nocturnal. The second was observed in the same habitats where domestic dogs were found, with activity patterns mainly crepuscular and nocturnal. These findings suggest that both species have altered their activity patterns. Actions must be focused on decreasing the interaction of these mammals with humans and domestic dogs.

“…Dogs may pose a great threat to Madagascar's endemic primates as dog owners use dogs for hunting wildlife, and free-roaming and feral dogs may venture into the forest to hunt on their own. Dogs also threaten lemurs through competition interference, and may transfer zoonotic diseases to endemic primates (Butler and du Toit 2002, Butler et al 2004, Manor and Saltz 2004, Galetti and Sazima 2006, Lenth et al 2008, Lacerda et al 2009, Vanak and Gompper 2009, Young et al 2011. While many dogs that enter Madagascar's forests can be considered to be feral, i.e., unowned and unhabituated to humans, many others are owned by individuals, but are not restrained.…”

Exotic carnivores, particularly feral and domestic dogs, represent a serious threat to Madagascar's endemic fauna. We obtained information from the local community about dogs in villages in and around Ranomafana National Park (RNP), Madagascar. Surveys were conducted (N=359) to assess local opinions of dogs, reasons for owning dogs, and the willingness of dog owners to participate in spay/neuter/vaccine programs. Of surveyed individuals without dogs (N=211), 58.9% of respondents reported negative feelings towards free-roaming dogs, with only 1% of respondents identifying free-roaming dogs as a positive aspect of village life. Of individuals with dogs (N=148), 8.1% of respondents reported using their dog for hunting, and 41.2% reported that their dog had killed at least one wild animal, with 11.8% reporting that this occurred on a weekly basis. Villagers approve of spay/neuter/vaccine programs and 90.3% of respondents with dogs state they would use them if freely available. The interest in veterinary services combined with a generally negative attitude towards free-roaming dogs indicates that a spay/neuter/vaccine program would be an effective means of controlling dog populations. RÉSUMÉLes carnivores exotiques, particulièrement les chiens domestiques et ceux retournés à l'état sauvage, représentent une menace sérieuse pour la faune endémique de Madagascar. Nous avons récolté des informations auprès des communautés riveraines sur les chiens vivant dans les villages et autour du Parc National de Ranomafana (RNP) au sud-est de Madagascar. Nous avons mené des enquêtes (N=359) afin d'évaluer les avis de la communauté locale sur les chiens, les raisons pour lesquelles les gens possèdent ces animaux et la volonté des propriétaires pour s'engager dans un programme de stérilisation/vaccination canine. Les villageois qui ne possédaient pas de chiens (N=211) représen-taient 58,9 % des personnes interrogées ; ils ont rapporté avoir des sentiments négatifs envers les chiens errants et seulement 1 % des personnes interrogées ont vu un aspect positif pour la vie du village dans les chiens errants. Parmi les propriétaires de chiens (N=148), 8,1 % des personnes interrogées ont rapporté utiliser leur chien pour la chasse et 41,2% des personnes interrogées indiquent que leur chien a déjà tué au moins un animal sauvage, dont 11,8 % rapportant que cela arrivait toutes les semaines. Les villageois approuvent le programme de stérilisa-tion/vaccination canine et 90,3 % des propriétaires de chiens y auraient volontiers recours si celui-ci était gratuit et librement disponible.

“…No entanto, a maioria dos estudos realizados no Brasil foi conduzida em áreas protegidas ou em ambiente periurbano (Horowitz, 1992;Monteiro-Fillho, 1995;Marinho-Filho et al,1998;Lacerda, 2002;Rodrigues, 2002;Gaspar, 2005;Negrão & Valladares-Pádua, 2006;Campos et al, 2007;Oliveira et al, 2008;Srbek-Araujo & Chiarello, 2005e 2008, sendo que poucos foram realizados em áreas rurais não protegidas da Mata Atlântica (Galetti & Sazima, 2006;Torres, 2008;Torres & Prado, 2010), locais relativamente mais expostos a invasão por cães domésticos.…”

Pinotti, Camila S. de Barros, Natalia Rossi, Gustavo de Oliveira, Camilla P. Pagotto, Thais K. (Williamson, 1992(Williamson, , 1993. Porém, em vários casos a proporção pode ser bem mais alta (Williamson & Fitter, 1996;Williamson 1996). Características morfológicas, fisiológicas e da história de vida parecem determinar quais espécies são invasoras eficientes (Manchester & Bullock, 2000). Por exemplo, árvores invasoras do gênero Pinus possuem maior massa de sementes, crescimento mais rápido e maior frequência de liberação de sementes do que as não invasoras (Rejmánek & Richardson, 1996). Segundo Ehrlich (1986), diversas espécies de vertebrados invasores possuem hábitos alimentares generalistas, curto tempo de geração, alta habilidade de locomoção, grande variação genética populacional e alta plasticidade ecológica.Outro fator que pode influenciar no sucesso de uma invasão é a vulnerabilidade da área alvo . Apesar de que todas as comunidades ecológicas podem, em certa medida, sofrer invasões biológicas (Crawley, 1987; Usher et al. 1988), características do habitat e fatores ambientais podem ser mais importantes do que características das espécies para determinar o sucesso de uma invasão (Newsome e Noble, 1986). É amplamente aceito que ambientes alterados pelo homem são mais facilmente invadidos e que distúrbios, tanto em escala ampla como local, são importantes na facilitação de invasões . Por outro lado, locais com pouca perturbação humana e com uma grande riqueza de espécies nativas tendem a conter poucas espécies invasoras . A maior probabilidade de 6 que áreas perturbadas apresentem recursos não utilizados, dado o efeito de distúrbios sobre espécies nativas, e que não abriguem agentes controladores, como predadores e competidores, podem ser as razões para a maior vulnerabilidade à invasão . No entanto, a probabilidade de invasão também depende da pr...
