“…Using a camera trap methodology, we documented for the first time the presence of at least 10 different individuals, including adults of both sexes, and possibly a pregnant female in a coastal wetland located in Nayarit. The relative abundance index obtained in this work (1.28 bobcat photographs / 100 camera days), is similar, for example, to that reported for the bobcat in coniferous forests in Virginia, USA (1.36;Kelly and Holub 2008), and in Tlaxcala, México (1.27;Flores-Morales et al 2019). It is even higher than at sites defined in the species distribution models as ideal ecosystem for the species, such as Sierra Gorda in Guanajuato, where relative abundance values of 0.15 were reported in submontane scrub and 0.09 in pine-oak forest (Charre- Medellín et al 2016).…”

El gato montés, Lynx rufus, es una de las seis especies de felinos silvestres que habitan en México. Se distribuye desde el nivel del mar hasta los 3,600 m, ocupando una gran variedad de hábitats entre los que se encuentran los desiertos, ecosistemas de montaña y humedales. Sin embargo, a la fecha, no existe información ecológica de la especie en humedales costeros. El objetivo general de este trabajo es proveer la primera información ecológica obtenida de forma sistemática sobre el gato montés en la Planicie Costera de Nayarit (PCN). Evaluamos su presencia histórica y actual, su abundancia relativa y patrones de actividad. Determinamos la presencia histórica del gato montés en la PCN mediante una búsqueda en bases de datos electrónicas utilizando las palabras: “Lynx”, “rufus”, “lince”, “bobcat” y “Nayarit”. Implementamos el protocolo del Censo Nacional del Jaguar usando cámaras trampa en un área de 72 km2 para documentar la presencia, distribución, abundancia relativa y patrones de actividad del gato montés. A través de la búsqueda en bases de datos encontramos 23 registros de gato montés en un área de al menos 3,000 km2 de la PCN. A partir de nuestro trabajo de campo obtuvimos 30 registros independientes con una abundancia relativa de 1.28 fotografías de gato montés / 100 días cámara. Documentamos la presencia de al menos 10 individuos diferentes, incluyendo adultos de ambos sexos y una hembra presuntamente embarazada. Su actividad es nocturna; 40 % de los registros ocurrieron entre las 00:00-06:00 hr. El gato montés habita los ecosistemas costeros de Nayarit. Los valores elevados de abundancia relativa sugieren una población estable en la PCN con respecto a lo que ha sido reportada en hábitat ideales para la especie tales como los matorrales y bosques templados. Su actividad nocturna coincide con lo que reportan otros trabajos para la especie. Aunque, en general, el gato montés se adapta bien al disturbio generado por actividades humanas, los impactos que estas tienen sobre sus poblaciones en los humedales costeros aún se desconocen. Para asegurar la permanencia de sus poblaciones es necesario realizar futuros estudios sobre su dieta, reproducción, ámbito hogareño y conectividad genética de la especie en los ecosistemas costeros del occidente de México.

“…Our results suggest that the wolf did not avoid areas attended by humans (cf. Flores‐Morales et al , , for the coyote Canis latrans ). Consistent with previous works (Darimont et al , ; Theuerkauf et al , ; Theuerkauf, ; Nelson et al , ), in PNP the wolf may avoid the contact with humans by concentrating its activity bouts in the night hours.…”

“…Human disturbance (i.e. human activity, distance to settlements and livestock grazing) has also been reported as an important factor shaping the behaviour of large mammals (Flores‐Morales et al , ; Yang et al , ), which may modify their spatiotemporal behaviour to reduce encounters with humans (Theuerkauf et al , ; Yang et al , ). The alteration of spatiotemporal patterns of activity can increase species exposure to local threats, including predation and poaching (Jacob & Brown, ; Sih et al , ; Mori et al , ).…”

Spatiotemporal mechanisms of coexistence in an European mammal community in a protected area of southern Italy

Assessing the spatiotemporal overlap amongst animal species living in sympatry helps to shed light on mechanisms of interspecific coexistence. We analysed the spatiotemporal coexistence in a predator–prey system through multiyear camera trapping, in a mountainous protected area of southern Italy (January 2012–January 2017). Temporal activity patterns and their interspecific overlap, as well as spatial overlap, were estimated for a top predator, that is the wolf Canis lupus, three species of wild ungulates, four mesocarnivores, one small herbivore, livestock and humans. A wide nocturnal temporal overlap was detected between the wolf and almost all the other species (71–91%). The highest temporal (91%) and spatial (63%) overlaps were reported between the wolf and the red fox Vulpes vulpes. For wolf‐ungulate pairs, the highest temporal overlap (88%) was reported for the wild boar Sus scrofa, its local main prey. Considering all the other species pairs, spatial overlap was low (i.e. lower than 45%), whereas temporal overlap was substantial (71–91%). Our findings support a significant role of interspecific spatial partitioning in shaping coexistence amongst considered species, which might be influenced by differences in spatial distribution of different food resources.

Resting metabolic rates increase with elevation in a mountain‐dwelling lizard

Individuals that inhabit broad elevational ranges may experience unique environmental challenges. Because temperature decreases with increased elevation, the ectotherms living at high elevations have to manage limited activity time and high thermoregulatory effort. The resting metabolic rate (RMR) of a postabsorptive animal is related to its total energy requirements as well as many other fitness traits. Mesquite lizards (Sceloporus grammicus) living on La Malinche Volcano, Mexico, inhabit a wide elevational range with some populations apparently thriving above the tree line. We measured the RMR of lizards from different elevations (i.e., 2,600, 3,200, and 4,100 m) at four ecologically relevant temperatures (i.e., 15, 25, 30, and 35 °C) and found that RMR of mesquite lizards increased with temperature and body mass. More importantly, lizards from the high‐elevation population had mass specific RMR that was higher at all temperatures. While the higher RMRs of high‐elevation populations imply higher metabolic costs at a given temperature these lizards were also smaller. Both of these traits may allow these high elevation populations to thrive in the face of the thermal challenges imposed by their environment.
