Broad scale population estimates of declining species are desired for conservation efforts. However, many secretive including large carnivores, such often difficult. Based on published density obtained through camera trapping, presence/absence data, and globally available predictive variables derived from satellite imagery, we modelled occurrence a carnivore, the jaguar, across species' entire range. We then combined these models in hierarchical framework to estimate total population. Our...
Olfactory communication among mammals remains poorly studied yet may be key to understanding their ecology. This is particularly true for mammalian carnivores, which rely extensively on scent marking communication. Previous research suggests that carnivore latrines play a large role in both intra- and interspecific Despite the apparent complexity of mammal use latrines, little work has examined behavior patterns species visit latrines. We used motion-triggered video cameras study at ocelot...
The jaguar Panthera onca is threatened throughout its range and categorized as Near Threatened on the IUCN Red List. To inform conservation of population in Corcovado National Park, Costa Rica, size was estimated using data from a 3-month camera trap study. Individuals were identified their coat patterns. resulting density estimate 6.98 ± SD 2.36 individuals per 100 km 2 lower than expected. sex ratio 1.33 males female, minimum home ranges two 25.64 6.57 . Hunting pressure white-lipped...
Abstract Evaluating range‐wide habitat use by a target species requires information on occurrence over broad geographic regions, process made difficult rarity, large spatiotemporal sampling domains and imperfect detection. We address these challenges in an assessment of for jaguars ( Panthera onca ) outside protected areas Central America. Occurrence records were acquired within 12 putative corridors using interviews with knowledgeable corridor residents. developed Bayesian hierarchical...
Due largely to their success in undisturbed areas, the conservation of large carnivores is tied protected areas.However, because area requirements, -and -will also always be linked areas outside areas.Retaliatory killing jaguars near reserves and corridors between threatens severely decrease jaguar populations corridors, thus decreasing ecological viability for species.Resolving this conflict will allow utilize human-dominated landscape, provide opportunities corridor conservation, enhance...
Habitat characteristics and human activities are known to play a major role in the occupancy of jaguars Panthera onca across their range, however key variables influencing jaguar distribution Tortuguero National Park, Costa Rica, have yet be identified. This study evaluated Park surrounding area. Jaguar detection/non-detection data was collected using digital camera traps distributed within boundaries protected Local community members were also interviewed determine occurrence Park's buffer...
Human activities such as habitat degradation and fragmentation threaten biodiversity in Neotropical areas. This work proposes an analytical methodology to identify natural areas Central America with anthropogenic impact, analyzing the presence of antimicrobial resistance genes (ARGs) accordance their theoretical relationship human-related activities. Sixteen ARGs were quantified feces different individuals 13 jaguars (Panthera onca) pumas (Puma concolor) three conservation Costa Rica by...
Abstract Understanding how human modification of the landscape shapes vertebrate community composition is vital to understanding current status and future trajectory wildlife. Using a participatory approach, we deployed largest camera‐trap network in Mesoamerica date investigate anthropogenic disturbance occupancy co‐occurrence terrestrial species tropical biodiversity hotspot: Osa Peninsula, Costa Rica. We estimated richness different categories land protection with rarefaction analysis...
Connectivity of natural areas through biological corridors is essential for ecosystem resilience and biodiversity conservation. However, robust assessments in corridor are often hindered by logistical constraints the statistical challenges modeling data from multiple species. Herein, we used a hierarchical community occupancy model Bayesian framework to evaluate status medium large-sized mammals critical link Mesoamerican Biological Corridor (MBC) Costa Rica. We camera traps deployed...
<p>Existe poco conocimiento sobre el impacto que tienen los jaguares las tortugas marinas anidan en Parque Nacional Tortuguero, Costa Rica. Este estudio evaluó de la depredación jaguar tres especies (<em>Chelonia mydas</em>, <em>Dermochelys coriácea</em> y <em>Eretmochelys imbricata</em>) Tortuguero. Los reportes fueron obtenidos empleando dos metodologías, revisión literaria (eventos registrados antes del 2005) monitoreos semanales a lo largo playa...
Located in Costa Rica, Pacuare Nature Reserve has a long established history of wildlife monitoring programs primarily focused on species nesting marine turtles and the Agami herons (Agamia agami) found within reserve. Our research represents first assessment local terrestrial mammal populations. Data was collected by using seven camera trap stations distributed boundaries From April 2015 to March 2016, after total 1 643 nights, we were able identify 11 terrestrial mammalian six orders...
Abstract Understanding species‐environment relationships at large spatial scales is required for the prioritization of conservation areas and preservation landscape connectivity carnivores. This endeavour challenging jaguars ( Panthera onca) , given their elusiveness, local nature most jaguar studies, precluding extrapolation to larger areas. We developed an occupancy model using occurrence data across five countries Central America, collected from camera‐trap studies 2–12 months' duration,...
Abstract Aim Planning conservation action requires accurate estimates of abundance and distribution the target species. For many mammals, particularly those inhabiting tropical forests, there are insufficient data to assess their status. We present a framework for predicting species using jaguarundi ( Herpailurus yagouaroundi ), poorly known felid which basic information on is lacking. Location Mesoamerica South America. Time Period From 2003 2021. Taxa yagouaroundi. Methods combined...
Aunque se sabe que los jaguares (Panthera onca) habitan en el Área de Conservación Guanacaste, Costa Rica, existen sectores dentro del área donde no ha confirmado la presencia especie. Por lo tanto, presente nota documentamos primeros registros jaguar Península Papagayo, Guanacaste. Entre periodo comprendido entre febrero y agosto 2022 emplearon métodos invasivos, incluyendo cámaras trampa extracción ADN muestras fecales, para determinar especie estudio. Después 6,093 noches muestreo,...
La Iniciativa del Corredor Jaguar pretende mantener la conectividad de esta especie. En Costa Rica, iniciativa inició en el Subcorredor Biológico Barbilla-Destierro. este Subcorredor, se ha identificado pavimentación un camino lastre (asociado a las obras mitigación social Proyecto Hidroeléctrico Reventazón), como una potencial barrera para jaguar (Panthera onca) y otras especies. Este estudio sugiere método identificar los cruces fauna sobre camino. Se tomaron datos junio 2011 enero 2012....
Abstract Ocelots (Leopardus pardalis) are a wide-ranging felid species, occurring from southern United States to northern Argentina. They occupy various habitats and usually considered the most abundant wild cat species in Neotropics. However, genetic studies that include free-ranging Mesoamerican ocelots rare generally based on small sample sizes. This is first conservation genetics study Costa Rica second one Mesoamerica has conducted assessment of at countrywide scale. We evaluated...
Poca información ha sido generada sobre la biodiversidad del Refugio Nacional de Vida Silvestre Barra Colorado, Costa Rica. En el presente estudio determinamos abundancia relativa y patrón actividad ciertas especies mamíferos terrestres. Durante periodo 2014 se empleamos diez cámaras trampa, las cuales fueron distribuidas dentro refugio. Después un total 1 611 noches muestreo, identificaron 15 distribuidos en siete órdenes 11 familias. Las más abundantes Dasyprocta punctata, Leopardus...
