“…We determined potential prey species based on available literature (Hayward et al, 2016; Luja et al, 2020; Perera-Romero et al, 2021) and followed the protocol described by Sanderson & Harris (2012) for the organization and analysis of camera-trap photographs. We calculated the relative abundance index (RAI) using the formula proposed by Maffei et al (2004): RAI = ( C /SE) × 100 where C is the number of photographic captures, SE is the sampling effort (number of cameras per monitoring day) per 100 camera days (standard correction factor).…”

Habitat fragmentation threatens biodiversity worldwide, particularly affecting large-bodied species that require vast territories and move across long distances, including most large felids. The jaguar Panthera onca has lost more than half of its habitat throughout its range and its subpopulations are becoming isolated, making them susceptible to local extinction. Knowledge about the status of its subpopulations in highly fragmented environments is lacking but urgently needed. Using camera traps during 2019–2020, we estimated number of individuals, age classes and sex ratio, occupancy, relative abundance and density of jaguars in Nayarit, western Mexico. We also determined the relative abundance of potential prey and estimated the land-cover change rate during 1999–2019, using GIS. We found that a resident subpopulation of five adult females, two adult males and one cub, at a high density (5.3 individuals/100 km2), is supported by at least 14 wild prey species. Natural habitat in the area is rapidly decreasing because of expanding agriculture and shrimp farming: agricultural areas increased from 39 to 50% and mangroves decreased from 35 to 26% of the study area over 20 years. The high jaguar population density and the diversity and relative abundance of remaining wild prey are remarkable, considering that natural habitat in the area is highly fragmented, shrinking rapidly and embedded in a matrix of human-dominated land-cover types. Effective conservation actions are needed urgently, including the protection of patches with native vegetation, reforestation to maintain connectivity between these patches, and the involvement of local communities.

“…Moreover, water deposits commonly favor the presence of organisms that constitute an important food source for a variety of vertebrates (Gossner et al, 2020). Therefore, water availability can directly or indirectly affect population dynamics (Gandiwa et al, 2016), movement (Chamaillé‐Jammes et al, 2013), habitat use (Bennitt et al, 2014), spatial distribution (Paredes et al, 2017), and interspecific interactions (Perera‐Romero et al, 2021) of all terrestrial vertebrates.…”

Camera trapping reveals multispecies use of water‐filled tree holes by birds and mammals in a neotropical forest

2021

Using camera traps, we documented that 21 bird and 9 mammal species use water‐filled tree holes (dendrotelmata) in the seasonal tropical forest of the Calakmul Biosphere Reserve, in southern Mexico. These species visited dendrotelmata primarily for foraging and drinking. The overall use of dendrotelmata was equally frequent between dry and rainy seasons but drinking behavior increased among birds during the dry season. Abstract in Spanish is available with online material.

“…Thus, it is possible that the need to meet their water requirements outweighs the negative interactions among badger) and canids (Lehner 1981;Minta et al 1992;Clark et al 2015) the species in our study site. In previous studies it has been recorded that the probability of negative interactions between species might increase especially when there are limited resources such as water (Rosenstock et al 1999;Krausman et al 2006;Perera-Romero et al 2021). However, negative interactions, such as kicking, pushing, or chasing among species, when using waterholes were not recorded in our study site as in other studies (Rosenstock et al 2004).…”

“…Waterholes are sources of water for many species of different taxa, such as reptiles, birds, and mammals (Martínez-Kú et al 2008;Delgado-Martínez et al 2018), and several of these species also use waterholes as refuge and resting areas (Martínez-Kú et al 2008). However, species can also be negatively affected when visiting waterholes due to the increased risk of predation or competitive interactions (Rosenstock et al 1999;Krausman et al 2006;Hall et al 2013;Perera-Romero et al 2021).…”

Vertebrates visiting natural waterholes in a tropical seasonal habitat in central México

La distribución espacial y temporal de la disponibilidad de agua impacta el comportamiento de las especies. Particularmente en hábitats áridos, los pozos de agua son fuentes de agua para muchas especies. Presentamos registros interesantes de vertebrados que visitaron pozos de agua naturales mediante cámaras-trampa durante la estación seca en un bosque tropical seco del centro de México. Durante la estación seca (diciembre de 2015, mayo de 2016 y abril-mayo de 2019), colocamos siete cámaras-trampa durante 135 días en siete pozos de agua. Este método utilizado fue parte de las actividades de monitoreo y conservación, implementadas dentro de una amplia unidad de manejo de vida silvestre en el centro de México. Registramos 20 especies de vertebrados visitando los pozos de agua: 15 mamíferos, cuatro aves, y un reptil. La co-ocurrencia entre especies sin interacciones negativas, y algunos registros de conducta incluyeron: eventos de juego, acicalamiento y frotamiento contra piedras; se observó a algunas especies esperando su turno para beber. Pudimos identificar al menos cuatro individuos de Mephitis macroura. Nuestro estudio también enfatiza un aspecto básico, pero quizás subestimado en los últimos años producto del uso de cámaras-trampa: la observación cualitativa de animales a través de fotografías. Estas observaciones pueden revelar aspectos básicos e interesantes de la historia natural de las especies que permiten mejorar el conocimiento sobre la coexistencia en un mismo lugar.
