Interspecies somatic cell nuclear transfer (iSCNT) is an emerging assisted reproductive technology (ART) for preserving Nature’s diversity. The scarcity of oocytes from some species makes utilisation of readily available oocytes inevitable. In the present study, we describe the successful cloning of coyotes (Canis latrans) through iSCNT using oocytes from domestic dogs (Canis lupus familiaris or dingo). Transfer of 320 interspecies-reconstructed embryos into 22 domestic dog recipients resulted in six pregnancies, from which eight viable offspring were delivered. Fusion rate and cloning efficiency during iSCNT cloning of coyotes were not significantly different from those observed during intraspecies cloning of domestic dogs. Using neonatal fibroblasts as donor cells significantly improved the cloning efficiency compared with cloning using adult fibroblast donor cells (P < 0.05). The use of domestic dog oocytes in the cloning of coyotes in the present study holds promise for cloning other endangered species in the Canidae family using similar techniques. However, there are still limitations of the iSCNT technology, as demonstrated by births of morphologically abnormal coyotes and the clones’ inheritance of maternal domestic dog mitochondrial DNA.

Although the domestic dog (Canis lupus familiaris) is today ubiquitous throughout most of South America, it may have been a relatively late arrival in Amazonia. A dog’s comparative value to contemporary indigenous people in the tropical lowlands of Northeastern South America relates directly to its role in hunting; otherwise, it can be regarded with the same ambivalence attributed to other exotic domesticates, most of which tend to be poorly integrated into indigenous human societies. Despite cultivating a formidable array of native plants and demonstrating a marked proclivity for pets, indigenous Amazonians had few, if any, native animal domesticates. The elaborate esteem bestowed on valued hunting dogs by indigenous societies in Northeastern South America can contrast markedly with their attitude toward other exotic animal domesticates. This is likely rooted in their ontological perspectives of animal others and may be based upon a pre-Columbian template of tamed autochthonous canids.

Os mamíferos desempenham um papel fundamental no ecossistema como o controle populacional e a regeneração de matas. Buscou-se com este trabalho, obter uma amostragem preliminar da mastofauna presente em um remanescente de floresta atlântica, utilizando-se de armadilha fotográfica, contribuindo com maiores informações a respeito do uso de habitat por estes animais na área de estudo, local característico de um corredor ecológico, devido a sua paisagem ser bem semelhante ao mesmo. Foram obtidos registros de seis espécies de mamíferos silvestres pertencentes a quatro famílias e três ordens: quatro Carnivora (Cerdocyon thous, Lontra longicaudis, Galictis cuja, Canis lupus familiaris), um Didelphimorphia (Didelphis aurita) e um Rodentia (Hydrochoerus hydrochaeris), sendo que não foi possível a identificação de uma espécie. Ressalta-se a importância da presença da espécie Lontra longicaudis, que possui o estado de conservação quase ameaçada no estado de São Paulo.

This communication describes two attacks by domestic and wild carnivores in Caceres County, localized in the Pantanal area, an extensive flooded plain in Mato Grosso State, Midwest region of Brazil. The first attack took place in an urban area and was caused by a Rottweiler dog (Canis lupus familiaris) created by the family of the victim. Another attack occurred in a rural area, caused by a jaguar (Panthera onca), which was disturbed while feeding, characterizing an unprovoked attack. Both the patients were wounded in the forearm, with different severity of the wounds. The lesions restricted to the forearm were the consequence of the victims using their arms as a shield, featuring the "defense" injuries, but the severity of the wounds were proportional to the strength of the attacking carnivore. Health staffs and emergency centers should be alert for soft tissue and bone injuries in the observed body regions after domestic and wild animal attacks.
