“…Causes of seasonal variation in detectability of eastern spotted skunks are unclear. However, patterns of detectibly and capture success of many carnivore species, including other species of skunk, may be attributed to season shifts in resource availability, home range size, habitat use, and foraging ability (Bailey , Bixler and Gittleman , Zapata et al , Cantú‐Salazar et al , Doty and Dowler ).…”

Eastern spotted skunk (Spilogale putorius) populations have declined throughout much of their range in the eastern United States over recent decades. Declines have been attributed to habitat loss or change, increased competition with sympatric mesocarnivore species, or disease. To better understand the extant distribution of spotted skunks in the Appalachian Mountains of western Virginia, USA, we used a detection‐non‐detection sampling approach using baited camera traps to evaluate the influence of landscape‐level environmental covariates on spotted skunk detection probability and site occupancy. We conducted camera trap surveys at 91 sites from January to May in 2014 and 2015. Spotted skunk occupancy was associated with young‐aged forest stands at lower elevations and more mature forest stands at higher elevations. Both land cover types in this region can be characterized as having complex forest structure, providing cover that varies with stand age, species composition, elevation, and management regime. Our results provide insight into factors that influence spotted skunk spatial distribution and habitat selection, information that can be used to generate conservation assessments and inform management decisions. © 2017 The Wildlife Society.

“…Se observaron varios ejemplares de zorrillo pigmeo en la localidad de Acapulco en el sitio de Brisas del Marqués. Éste es el mustélido más pequeño del continente americano, además de ser una especie endémica y de distribución restringida, a las selvas bajas de la costa del Pacífico, que va desde Sinaloa hasta el istmo de Tehuantepec en Oaxaca (Cantú-Salazar et al, 2005;Medellín et al 1999). El zorrillo pigmeo ya había sido reportado en Puerto Marqués, en la década de los setenta, momento en el cual se capturaron 19 ejemplares en sitios rocosos con suelos suave (López-Forment y Urbano, 1979).…”

RESUMENLas selvas secas son uno de los ecosistemas más diversos y amenazados en Latinoamérica. Se realizó un muestreo de la mastofauna terrestre en dos localidades de las selvas secas del estado de Guerrero en el Pacífico mexicano. En total se registraron 44 especies de mamíferos terrestres que pertenecen a 20 familias y 8 órdenes, lo que representa el 9% de la mastofauna terrestre del país y el 29% para el estado de Guerrero. De las especies encontradas, 9 son endémicas a México. Sobre el estado de conservación, 3 de ellas se encuentran amenazadas y 3 en peligro de extinción de acuerdo a la lista mexicana de especies en riesgo. A nivel mundial, 2 especies son consideradas vulnerables. Destacan los registros del zorrillo pigmeo (Spilogale pygmaea), la rata leñera (Hodomys alleni) y el jaguarundi (Herpailurus yagouaroundi). Para los murciélagos Musonycteris harrisoni y Myotis carteri se amplía su rango de distribución con los registros aquí presentados. La diversidad de mamíferos registrada enfatiza la importancia de conservar parches de selva en ambientes altamente urbanizados, así como la necesidad de estrategias que incrementen la conectividad entre los diferentes parches y que consideren las amenazas urbanas a la fauna en estos sitios.Palabras clave: Acapulco de Juárez, Guerrero, mamíferos, Omitlán, selva seca.ABSTRACTThe tropical dry forest represents one of the most diverse and threatened ecosystems in Latin America. We carried out a survey of the terrestrial mammals’ community in two locations at the Mexican Pacific region of dry forest in Guerrero state. We registered 44 species of mammals belonging to 20 families and 8 orders, representing 9 % of Mexico’s terrestrial mammals and 29 % of Guerrero’s. About 9 species of the mammals reported in this study are endemic to Mexico. About the conservation status, 3 species are classified as “threatened” and 3 as “endangered” in the Mexican list of endangered species. In the global context, 2 species are listed as vulnerable. Also, the presence of the pygmy skunk (Spilogale pygmaea), the allen’s woodrat (Hodomys alleni) and the presence of the jaguaroundi (Herpailurus yagouaroundi), is noteworthy. With the records in this study, we extend the known distribution of the bats Musonycteris harrisoni and Myotis carteri. The great diversity and peculiarity of the found mammals emphasize the importance of conserve forest patches in highly urbanized, also the need of strategies that increment the connectivity between the patches and consider the urban threats, as roadkill’s, in these sites.Key words: Acapulco de Juárez, dry forest, Guerrero, mammals, Omitlan.

“…Changes in abiotic factors such as climate across habitats and seasons, as well as anthropogenic disturbance, lead to spatial and temporal variation in food availability [119][120][121][122][123][124][125][126][127], and as food availability changes, many animals respond by altering their diet [119,124,[128][129][130][131]. For example, mantled howler monkeys (A. palliata) on Barro Colorado Island, Panama spend 46% of feeding time consuming fruits during months when fruit availability is high but spend 85% of feeding time consuming leaves during months when fruit availability is low [119].…”

IntroductionAs sequencing technology makes data generation faster, cheaper, and more comprehensive, studies of gut microbial communities are multiplying at an astonishing rate. As a result, our understanding of the host-gut microbe relationship is constantly improving. Studies to date have demonstrated that the gut microbiota contributes to host nutrition, health and behavioral patterns by providing energy and nutrients, improving immune function, and influencing the production of neuroactive molecules [1][2][3][4][5][6][7][8][9][10][11][12]. Changes in the composition of the gut microbial community are known to lead to changes in its function, which can alter host nutrition, health and behavior [6,[13][14][15][16][17][18][19][20][21][22][23]. Environmental factors such as diet or social contact are largely responsible for determining the composition of the gut microbial community [24][25][26][27][28][29][30][31], but host genotype also affects the abundances of some microbial genera [28,32,33].Because host-gut microbe relationships are influenced to some extent by host genotype, and gut microbial community composition differs according to host phylogeny [34][35][36], discussions of the co-evolution of host and gut microbiota are common in the current literature [7,[34][35][36][37]. Some researchers argue that since microbes are found in animals as simple as earthworms, the co-evolution of animals and bacteria has been Co-evolution in context: The importance of studying gut microbiomes in wild animals Abstract Because the gut microbiota contributes to host nutrition, health and behavior, and gut microbial community composition differs according to host phylogeny, co-evolution is believed to have been an important mechanism in the formation of the host-gut microbe relationship. However, current research is not ideal for examining this theme. Most studies of the gut microbiota are performed in controlled settings, but gut microbial community composition is strongly influenced by environmental factors.To truly explore the co-evolution of host and microbe, it is necessary to have data describing host-microbe dynamics in natural environments with variation in factors such as climate, food availability, disease prevalence, and host behavior. In this review, I use current knowledge of host-gut microbe dynamics to explore the potential interactions between host and microbe in natural habitats. These interactions include the influence of host habitat on gut microbial community composition as well as the impacts of the gut microbiota on host fitness in a given habitat. Based on what we currently know, the potential connections between host habitat, the gut microbiota, and host fitness are great. Studies of wild animals will be an essential next step to test these connections and to advance our understanding of host-gut microbe co-evolution. KeywordsGut microbiota • host-microbe • co-evolution • habitat • ecology • fitness occurring for more than 800 million years [38,39]. Additionally, the increased complexity and stabilit...
