Abstract

Physical and genetic isolation are recognized as significant threats to wildlife, especially in large carnivores inhabiting fragmented landscapes. We conducted an initial genetic assessment of pumas (Puma concolor) using 19 microsatellite loci for the emblematic puma population in the Torres del Paine UNESCO Biosphere Reserve in southernmost Chile, which exhibits some distinctive phenology that some local people speculate may be due to isolation and inbreeding depression. We extracted DNA from 385 scats collected in the field, of which 96 were identified as puma, representing 20 unique individuals. Torres del Paine pumas exhibited an Ho (0.51) only slightly lower than He (0.53), with 2 of the 19 loci significantly out of Hardy–Weinberg Equilibrium. Tests for a recent bottleneck of the population were not significant. The small sample size of individuals notwithstanding, these results seemingly do not support high levels of inbreeding. We also identified individual pumas in the field and assessed them for observable cowlicks (twirls of fur on their backs), a trait some have associated with genetic inbreeding depression in other puma populations. A total of 7 of 39 pumas exhibited cowlicks, consistent with geographic patterns of cowlicks within the species. Our tests exploring population structure among local pumas provided the most support for a single-population cluster, but we explored secondary structures as well, given its conservation implications. We encourage additional sampling in the region to further explore population structure and connectivity and determine the conservation status of the region's pumas to guide the development of best strategies to ensure their persistence.

Abstract

Wildlife must adapt to human presence to survive in the Anthropocene, so it is critical to understand species responses to humans in different contexts. We used camera trapping as a lens to view mammal responses to changes in human activity during the COVID-19 pandemic. Across 163 species sampled in 102 projects around the world, changes in the amount and timing of animal activity varied widely. Under higher human activity, mammals were less active in undeveloped areas but unexpectedly more active in developed areas while exhibiting greater nocturnality. Carnivores were most sensitive, showing the strongest decreases in activity and greatest increases in nocturnality. Wildlife managers must consider how habituation and uneven sensitivity across species may cause fundamental differences in human–wildlife interactions along gradients of human influence.

Abstract

Poca información ha sido generada sobre la biodiversidad del Refugio Nacional de Vida Silvestre Barra del Colorado, Costa Rica. En el presente estudio determinamos la abundancia relativa y el patrón de actividad de ciertas especies de mamíferos terrestres. Durante el periodo 2014 se empleamos diez cámaras trampa, las cuales fueron distribuidas dentro del refugio. Después de un total de 1 611 noches de muestreo, se identificaron 15 especies de mamíferos distribuidos en siete órdenes y 11 familias. Las especies más abundantes fueron Dasyprocta punctata, Leopardus pardalis, Tayassu pecari,Mazama temama, Pecari tajacu y Tapirus bairdii, mientras que Tamandua mexicana reportó la menor abundancia. Se estimaron los patrones de actividad para ocho especies, los cuales fueron similares a lo previamente descrito en la literatura. Estudios adicionales son necesarios con el fin de incrementar nuestro conocimiento sobre la biodiversidad del refugio, información que será esencial para el adecuado manejo del área.

Abstract

Little is known about the effects of jaguars on the population of marine turtles nesting in Tortuguero National Park, Costa Rica. This study assessed jaguar predation impact on three species of marine turtles (Chelonia mydas, Dermochelys coriáceaand Eretmochelys imbricata)that nest in Tortuguero beach. Jaguar predation data was obtained by using two methodologies, literature review (historical records prior the year 2005) and weekly surveys along the 29 km stretch of beach during the period 2005-2013. Our results indicated that jaguar predation has increased from one marine turtle in 1981 to 198 in 2013. Jaguars consumed annually an average of 120 (SD= 45) and 2 (SD= 3) green turtles and leatherbacks in Tortuguero beach, respectively. Based on our results we concluded that jaguars do not represent a threat to the population of green turtles that nest in Tortuguero beach, and it is not the main cause for population decline for leatherbacks and hawksbills. Future research should focus on continuing to monitor this predator-prey relationship as well as the factors that influence it so the proper management decisions can be taken. Existe poco conocimiento sobre el impacto que tienen los jaguares sobre las tortugas marinas que anidan en el Parque Nacional Tortuguero, Costa Rica. Este estudio evaluó el impacto de la depredación de jaguar sobre tres especies de tortugas marinas (Chelonia mydas, Dermo-chelys coriáceay Eretmochelys imbricata)que anidan en Tortuguero. Los reportes de depredación fueron obtenidos empleando dos metodologías, revisión literaria (eventos registrados antes del 2005) y monitoreos semanales a lo largo de la playa (durante el periodo 2005-2013). La depredación del jaguar se ha incrementado de una tortuga en 1981 a 198 tortugas en 2013. Asimismo, los jaguares consumieron anualmente un promedio de 120 (SD= 45) y 2 (SD= 3) tortugas verdes y tortugas baula en Tortugue-ro, respectivamente. Nuestros resultados indican que los jaguares no representan una amenaza para la población de tortugas verdes que anida en Tortuguero, y no son la causa principal de la disminución poblacional de la tortuga baula y carey. No obstante, se recomienda continuar con el monitoreo con el fin de entender cómo esta interacción depredador-presa evolucionará en el futuro.

Abstract

The article discusses the video monitoring program for the species Panthera onca male jaguar cubs captured in Tortuguero beach, Costa Rica on December 7, 2013. Topics covered include installation of camera-trap with video for observing the gestation of cubs suckling milk from their mother within six months until 11 months and vocal calls of adult female to attract her male cubs. Other observations include the female cat grooming the cubs that can help in understanding behavioral development.
