“…To improve occupancy detection probabilities for Neotropical large carnivores ( Panthera onca , Puma concolor , Linnaeus 1771, and Tremarctos ornatus , Gervais 1855), as well as further improving the precision of occupancy estimates for wildlife in general, we recommend three 600 m transects for sign-based surveys (Isasi-Catalá et al., 2019; Márquez et al., 2017), effectively increasing sampling in the cell by a factor of six as compared to this study.…”

In 2013, we conducted a baseline study on the presence, distribution and occupancy of medium- to large-sized mammals in Bolivia along the San Buenaventura-Ixiamas road that runs parallel to the Madidi National Park and Natural Area of Integrated Management boundary and cuts through the Tacana Indigenous Territory and a number of neighboring private properties. Establishing a 3 km buffer on each side of the road, we studied an 865 km2 area divided into 1 km2 cells and sampled a total of 356 of these cells. In each cell, we established one 300 m transect divided into 25 m sections and registered wildlife sign, mainly footprints, from eight wildlife species or species groups. The transects were placed either along streams (75% of cells) or within forest (25% of cells). Using single-season single-species occupancy models we estimated occupancy (ψ) for Tapirus terrestris (ψ = 0.39), Pecari tajacu (ψ = 0.5), Mazama americana (ψ = 0.56), Dasyprocta spp. (ψ = 0.59), Cuniculus paca (ψ = 0.56), Leopardus spp. (ψ = 0.33), and use for Tayassu pecari (ψ = 0.17) and Panthera onca (ψ = 0.11). Occupancy and use results verified community perceived wildlife corridors between Madidi and its area of influence. We identified additional corridors along many streams crossing the San Buenaventura-Ixiamas road. This connectivity is not only important for wildlife, but also from a food security perspective for the indigenous communities that depend on wildlife as an important source of protein. The results will be used to mitigate the impact of road improvements through the identification of priority areas for maintaining connectivity between Madidi and the surrounding landscape.

“…Silvestre et al (2021) señalan que la reducción de la insostenibilidad se da cuando las comunidades se involucran en planes de manejo para conservar la biodiversidad y satisfacer necesidades económicas. Tal como sucede también en Tamshiyacu Tahuayo con la cacería de ungulados (Hurtado-Gonzales y Isasi-Catalá et al, 2016), en donde los pobladores desarrollaron planes de manejo con acuerdos sustentados en actas comunales. Es decir, los acuerdos de caza son importantes para la conservación de especies (Oliveira y Calouro, 2019).…”

Los pueblos indígenas secoyas y kichwas de la cuenca alta del Putumayo cazan mayormente Cuniculus paca “majás”, Pecari tajacu “sajino” y Tayassu pecari “huangana”, debido a su sabor agradable, mayor biomasa y precio en el mercado. Es por ello que la evaluación de la sostenibilidad de la caza es muy importante para que las comunidades nativas aseguren su alimentación y beneficios económicos. Con ese propósito y la de obtener registros cuantificables, entre el 2017 y 2019 se realizaron evaluaciones de fauna silvestre usando métodos de transectos en banda, registros de huella y de cámaras trampa. La densidad poblacional de pecaríes se obtuvo de la división del número de individuos registrados en el área de estudio. Para el cálculo de la densidad de C. paca, se utilizó el conteo de madrigueras. La presión de caza se estimó obteniendo información sobre el número de animales aprovechados en la zona de caza, recopilados mediante registros de caza y entrevistas a cazadores. Se usaron el modelo de cosecha y consenso cultural para evaluar la sostenibilidad de la caza. Los resultados de este estudio demuestran que la caza está siendo sostenible en las tres especies mayormente aprovechadas. Cabe indicar que, durante el 2019, la especie T. pecari no fue registrada mediante transectos, cámaras trampa ni huellas en las comunidades de Mashunta y Belén, pero fue aprovechada y evidenciada en los registros de caza. En conclusión, las comunidades de los pueblos indígenas secoyas y kichwas realizan cacería sostenible y en consecuencia pueden implementar planes de manejo con fines comerciales.

“…Occupancy models indirectly assess the abundance of the species, given the strong positive correlation between abundance and occupancy when the sampling design is established according to the home range of each species (Royle & Dorazio 2008). Therefore, occupancy was estimated considering camera-trap stations and around each station sampling units of 1 km² and 0.04 km 2 for species with large and small home range, respectively (Isasi-Catalá et al 2016). Detection history matrices were constructed for the 136 sampling units or sites (S = 136) and three occasions or visits (K = 3) defined each as a 10-day period (TC=10).…”

Protected areas, such as the 17,000 km² Manu National Park in Peru, are important for vulnerable species such as the jaguar, and population studies are needed to understand their conservation status. We did a short-term study using 136 paired camera traps stations deployed in three blocks across an area of 820 km² in Manu National Park to estimate: the density and distribution of jaguars, evaluate the availability and distribution of key prey (eight mammals and a bird), and investigate the use of space by predators, using occupancy models that considered environmental variables, prey availability, and competitors. Most prey species had an occupancy (psi) greater than 0.70, without clear patterns in the use of space. The use of space was intensive for ocelot (psi = 0.83, ES = 0.08) and jaguar (psi = 0.67, ES = 0.33), and less intensive for puma (psi = 0.25, SE = 0.07), yet without clear patterns related to the environmental variables we evaluated, the availability of prey and the presence of competitors. We estimate a jaguar density of 2 (ES=0.92; 95% CI =0.8-4.7) to 2.5 (ES=1.07, 95% CI = 1.1-5.6) ind/100 km², corresponding to a population of 193-241 jaguars for the lowlands of Manu. We conclude that jaguars are apparently abundant, both large carnivores and their prey can be found throughout the lowlands of the park, and their presence is not affected by spatial variations in habitat and human pressures.
