The latest taxonomic, distributional, habitat and conservation status information is presented for a total of 91 species of marine and terrestrial mammals presently or historically known from Nova Scotia. Four of them are extirpated and one is extinct. Of the 86 remaining species 51 are terrestrial (46 native, 5 introduced). The terrestrial mammals include 9 species of Insectivora, 6 (+ one tentative) of Chiroptera, one Primate, 12 Carnivora, 1 Perrissodactyla, 3 Artiodactyla, 19 Rodentia and 1 Lagomorpha. Native species include Boreal, Transition Zone and Austral elements, the result of Nova Scotia’s mid-latitude position on the continental coast.The 32 recorded marine species include 6 Carnivora (5 seals, walrus) and 26 Cetacea: Delphinidae (10 species), Phocoenidae (1), Monodontidae (1), Kogiidae (2), Physeteridae (1), Ziphiidae (4), Eschrichtiidae (1, extirpated), Balaenopteridae (5) and Balaenidae (1).Since 1971 four small mammal species (Sorex gaspensis, S. dispar, Glaucomys volans and Microtus chrotorrhinus) have been added to the provincial fauna, as a result of the first systematic and intensive sampling ever done in Nova Scotia. All are disjunct and three of them are restricted to forested talus habitats in the Cobequid Mts. or the Cape Breton Highlands. With the two disjunct species already known (Sorex arcticus maritimensis and Peromyscus leucopus caudatus), there are 6 disjunct mammals in the province, comprising 14.3 % of native non-volant terrestrial mammals, 33 % of insectivores and 18.8 % of native rodents. Two of them (Sorex gaspensis and Microtus chrotorrhinus) occur only on Cape Breton Island. No other area of similar size north of Mexico has a comparable proportion of disjunct mammals.Cape Breton Island historically has had a depauperate mammal fauna, lacking 8 species that were present on the adjacent mainland. The building of the connecting Canso Causeway in 1953-55 had a major zoogeographic impact, as it caused the western third of the strait to freeze over in winter and allowed the invasion and establishment of four large mammal species (Canis latrans, Procyon lotor, Mephitis mephitis and Lynx rufus).Le document présente l’information la plus récente sur la taxonomie, la répartition, l’habitat et la situation de 91 espèces de mammifères marins et terrestres qui vivent actuellement ou ont déjà vécu en Nouvelle-Écosse. Quatre d’entre elles ont disparu et une est éteinte. Sur les 86 autres espèces, 51 sont terrestres (46 espèces indigènes et 5 espèces introduites). Les mammifères terrestres comprennent 9 Insectivora, 6 (+ une espèce provisoire) Chiroptera, un Primate, 12 Carnivora, un Perrissodactyla, 3 Artiodactyla, 19 Rodentia et un Lagomorpha. La Nouvelle-Écosse étant située à une latitude moyenne sur la côte continentale, les espèces indigènes qui y vivent sont des éléments de la zone boréale, de la zone de transition et de la zone australe.Parmi les 32 espèces marines signalées, on compte 6 Carnivora important a (5 phoques et le morse) et 26 Cetacea: Delphinidae (10 espèces), Phocoenidae (1), Monodontidae (1), Kogiidae (2), Physeteridae (1), Ziphiidae (4), Eschrichtiidae (1, disparue), Balaenopteridae (5) et Balaenidae (1).Depuis 1971, à la suite du premier échantillonnage systématique et intensif mené en Nouvelle-Écosse, quatre espèces de petits mammifères (Sorex gaspensis, S. dispar, Glaucomys volans et Microtus chrotorrhinus) se sont ajoutées aux espèces fauniques de la province. Ce sont toutes des espèces disjointes, et trois d’entre elles sont confinées aux talus d’éboulis boisés des monts Cobequid ou des hautes-terres du Cap-Breton. Si on inclut les deux espèces disjointes déjà connues (Sorex arcticus maritimensis et Peromyscus leucopus caudatus), il existe 6 espèces disjointes de mammifères dans la province, qui représentent 14,3 % des mammifères terrestres indigènes qui ne volent pas, 33 % des Insectivores et 18,8 % des Rongeurs indigènes. Deux d’entre elles (Sorex gaspensis et Microtus chrotorrhinus) ne sont présentes que dans l’île du Cap-Breton. Au nord du Mexique, aucune autre région de taille semblable n’a une telle proportion d’espèces disjointes de mammifères.Dans le passé, l’île du Cap-Breton renfermait relativement peu de mammifères : on y trouvait 8 espèces de moins que dans la partie continentale de la Nouvelle-Écosse. La construction de la levée de Canso en 1953-1955 a eu un impact important zoogéographique du fait que, depuis, le tiers ouest du détroit gèle durant l’hiver, ce qui a permis à quatre espèces de gros mammifères (Canis latrans, Procyon lotor, Mephitis mephitis et Lynx rufus) de gagner l’île et de s’y établir.

Wild Turkeys

Wild Turkey (Meleagris gallopavo Linnaeus, 1758) populations have grown considerably in the Midwestern U.S. alongside mesocarnivores, such as coyotes (Canis latrans Say, 1823) and bobcats (Lynx rufus (Schreber, 1777)). However, few studies have assessed habitat overlap between mesocarnivores and turkeys with a goal to understand potential impacts of mesocarnivores on turkeys. We captured and radiomarked bobcats, coyotes, and Wild Turkey hens in southern Illinois during 2011–2013 in an agricultural landscape and created single-species resource selection and overlap models. Wild Turkeys and bobcats demonstrated concentrated use in forested areas, whereas coyote use was highest in agricultural areas. We documented Wild Turkey nests (n = 107) and hen mortalities (n = 28), which were used to model the effect of bobcat, coyote, and Wild Turkey habitat use on turkey nest success and mortality. Increased coyote use was associated with higher nest success and increased turkey use was associated with higher probability of mortality. These findings suggest that top predators, such as coyotes, may be important and beneficial for ground-nesting avian species. With coyotes acting as the top predator throughout much of the Midwest, they are likely reducing densities of other important turkey nest predator species, thereby increasing nest success.

Canid Species

To investigate interspecific relationships between gray foxes (Urocyon cinereoargenteus) and sympatric coyotes (Canis latrans) and bobcats (Lynx rufus), we quantified occurrence of food items in carnivore scats and used relative abundances of scats on transects to assess space use. Dietary-overlap indices between the two canid species were high during summer and fall ([Formula: see text] = 0.89) when fruits were prevalent in scats of both species, and were lower during winter and spring ([Formula: see text] = 0.70) when fruits were less available. Foxes differed most from coyotes in their relatively less frequent ungulate consumption. Fox–bobcat dietary-overlap indices were relatively low in summer and fall ([Formula: see text] = 0.37) and greater in winter and spring ([Formula: see text] = 0.74). Foxes differed most from bobcats in their more frequent consumption of fruits and less frequent consumption of lagomorphs. Abundance of fox scats was positively correlated with abundance of coyote scats during both winter–spring (r = 0.52, p = 0.02) and summer–fall (r = 0.75, p < 0.001) and with abundance of bobcat scats during winter–spring (r = 0.59, p < 0.01) and summer–fall (r = 0.22, p > 0.10). Thus, despite similarities in diet, we found no evidence that gray foxes avoided these larger predators in space.

And Behavior

Previous research showed that Coyotes (Canis latrans) and other canids might be more vulnerable to capture near the boundary or outside of their home ranges, making the capture of specific individuals within their territories difficult. Information concerning capture vulnerability relative to home range boundaries for other carnivores is lacking. During a four-year study of carnivore ecology in Kansas, we compared capture locations of Coyotes, Bobcats (Lynx rufus), and Raccoons (Procyon lotor) to their home range boundaries to determine if they were more likely to be captured inside, or near the periphery of, their home ranges. Resident Coyotes were captured disproportionately more often (P < 0.01) near the periphery of their home ranges, whereas Bobcats, Raccoons, and transient Coyotes were captured equally (P > 0.05) in both areas of their home ranges. Differences in capture vulnerability within and between species might be related to differences in social organization and behavior.

Existe poca información acerca del ciclo silvestre de Toxoplasma gondii en carnívoros y marsupiales silvestres en México. El objetivo de este estudio fue determinar la presencia de anticuerpos contra T. gondii en carnívoros y marsupiales silvestres en el noreste de México. La frecuencia de T. gondii en los especímenes capturados fue: margay (Leopardus wiedii; n=3; 33%), jaguarundi (Puma yagouaroundi; n=2; 0%), lince (Lynx rufus; n= 1; 100%), coatí (Nasua narica; n=7; 42%), coyote (Canis latrans; n=4; 25%), zorra gris (Urocyon cinereoargenteus; n=3; 66%), zorrillo (Conepatus leuconotus; n=1; 0%), y tlacuache (Didelphis sp.; n=5; 20%). Se comprueba la infección natural con T. gondii en carnívoros y marsupiales silvestres en el noreste de México.
