“…1). There are two climates: one sub-humid at elevations 1400 m and the other hot sub-humid <1400 m. Principal vegetation types include pine-oak forest, broadleaf forest, tropical deciduous forest, agriculture and anthropogenic grassland (Monroy-Vilchis et al, 2008a;Zepeda et al, 2008).…”

The composition and energetic content of puma (Puma concolor) diet in Sierra Nanchititla Natural Reserve (SNNR), Mexico, were determined. We collected 183 scats, where 27 components were identified by occurrence (88.07% mammals). The puma's diet was mainly composed of armadillo (Dasypus novemcinctus, 40.33%), white-nosed coati (Nasua narica, 11.93%) and white-tailed deer (Odocoileus virginianus, 6.17%). Energetic analysis of prey indicates that the puma prefers those with higher energetic content (kcal/kg). The prey with the most energetic contribution is armadillo (2398.70 kcal/kg), followed by white-nosed coati (2225.25 kcal/kg) and finally white-tailed deer (2165.52 kcal/kg). The differences in energetic content between prey species were statistically significant. The number of individuals killed/year on average to support a puma was 51 armadillos, 16 white-tailed deer and 7 white-nosed coatis. The results indicate a greater consumption of prey that provide more kilocalories to the predator, and suggests the importance of quality meat in the diet of pumas.

“…El presente estudio, sumado a posteriores iniciativas, que continúen documentando la presencia de felinos en zonas poco exploradas de la costa del Pacífico, son particularmente necesarias para delimitar nuevas áreas de conservación de felinos en: áreas del Bajo Balsas que colindan con el Estado de México y Guerrero en el Este, los bosques secos del Noroeste del Bajío, Este del Eje Neovolcánico y la Sierra Madre del Sur. Estas nuevas coberturas permitirían incrementar la conectividad entre poblaciones, para establecer una red con las pocas áreas naturales protegidas existentes del centro y occidente del país como Jalisco y el Estado de México (Monroy-Vilchis, Sán-chez, Aguilera-Reyes, Suarez, & Urios, 2008;Aranda, Botello, & López-de Buen, 2012). De esta manera, la exploración de todas estas áreas, permitirá seguir incrementando el conocimiento sobre los factores que determinan los patrones de distribución de felinos a lo largo de gradientes ecológicos, permitiendo contar con mayores elementos para enfrentar el impacto humano actual y amenazas futuras como el cambio climático, el cual se anticipa tendrá un impacto significativo en la región al aumentar la temperatura promedio (3.6°C) y disminuir la precipitación anual promedio (-7.8%) en las próximas décadas (Sáenz-Romero et al, 2010;Sáenz-Romero et al, 2012) AGRADECIMIENTOS Agradecemos el apoyo en campo brindado por estudiantes del Laboratorio de Ecología de Vertebrados Terrestres Prioritarios.…”

Distribution patterns of wild felids (Carnivora: Felidae) in the dry tropics of Central-Western Mexico. The Michoacán state is characterized by the existence of important environmental heterogeneity in terms of climate, topography and types of vegetation, which includes the worldwide endangered tropical dry forest. Some reports indicating the presence of the six species of felids occurring in Mexico in this region have been made; however, evidence to support these reports is scant, and filling this lack of information is particularly critical in the case of threatened species or habitats. The aim of this study was to systematize and analyze data distribution patterns of felids in the state of Michoacán, in the Central-Western Mexico. We conducted a review of literature and databases to compile species presence records in the study region. Moreover, we analyzed data obtained from ten years of field work conducted in the region, in which complementary methods (detection of direct and indirect evidence of species occurrence along transects, camera-trapping and interviews to local people) were applied to detect the presence of felid species. We compiled a total of 29 presence records of felids in the region from our review. Additionally, field work, which accumulated 1 107.5 km of walked transects, and 8 699 camera-trap days, produced 672 records of species presence. Lynx rufus was the species with the lowest number of records and the most restricted distribution. In contrast, the species with the greatest number of records was Leopardus pardalis (n = 343). In general, 89% of felids records occurred below 1 000 masl. Overall mean annual temperature of presence records was 24 °C and mean annual precipitation was 1 040 mm. The species whose presence records showed the most distinctive pattern, in terms of temperature and precipitation associated, was L. rufus (15.8 ± 1.3°C and 941 ± 171 mm). Results of a cluster analysis showed that areas supporting different combinations of eco-regions and types of vegetation could be grouped in five clusters having different assemblages of felid species and camera-trapping records. This study results useful to garner a more comprehensive view of the distribution patterns of felids in a region with important environmental contrasts and subjected to an increased human pressure. Moreover, this study provides insights that further our understanding of the relationship between environmental variables and felid distribution patterns which may have an impact for conservation and management strategies at the local and regional levels.

“…Recientemente se estimó para México, que la biomasa de los artiodáctilos, grupo que reúne a unas de las principales presas del jaguar (Rosas-Rosas et al 2008), aumenta en zonas con precipitaciones que van de 500-1 000mm ya que permiten alta productividad primaria (Mandujano & Naranjo 2010). La precipitación es un factor crítico que regula la productividad del ecosistema (Svoray & Karnieli 2010), según los valores de porcentaje de precipitación, los cuales reflejan la productividad primaria, esta zona presenta áreas con vegetación densa y pendientes pronunciadas, lugares menos perturbados que proveen refugio a este felino (Monroy-Vilchis et al 2008, Monroy-Vilchis et al 2009. Las características anteriormente mencionadas además de la temperatura y precipitación favorables se presentan en la zona ubicada como hábitat potencial del jaguar.…”

Potential distribution of jaguar, Panthera onca (Carnivora: Felidae) in Guerrero, Mexico: persistence of areas for its conservation. Studies about the permanence of natural protected areas are important, because they contribute to the promotion of the conservation target and to optimize economical and human resources of specific areas. Although there are no natural protected areas in Guerrero, it has suitable habitat for the jaguar, a common species used for planning and management of conservation areas. Since, there is actual evidence that environmental and anthropogenic variables may modify vertebrate species distribution with time, in this study we predicted the potential distribution of Panthera onca using MaxEnt for this Southeastern region. In addition, we made a projection considering the effect of a moderate climate change scenario, to evaluate the stability of the conservation area for a period of 24 years. Furthermore, we applied three threat scenarios for the actual prediction to define conservation priorities areas. In our results, we have found that 18 361Km 2 (29%) of this state has a permanent suitable habitat for jaguar conservation in the Sierra Madre del Sur and Pacific coast, with a possible loss of 2 000km 2 in 24 years. This habitat is characterized by a 56% of temperate forest (mainly conifers and hardwoods 34%), and 35% of tropical deciduous forest. With the projections, the Southeastern region resulted with the higher anthropogenic impacts, while at the same time, an area of 7 900km 2 in the Central-Western state was determined as a priority for conservation. To assure jaguar conservation, we propose the inclusion of this new conservation area, which is located in the Sierra Madre del Sur, with which we may potentially preserve other 250 species of threatened vertebrates. This way, the suggested habitat conservation may represent a local effort in Guerrero and will strengthen the biological corridor network for P. onca protection in Latin America. Rev. Biol. Trop. 60 (3): 1357-1367. Epub 2012 September 01.
