“…The puma can be found in different types of land cover with various levels of human modification (e.g., [ 23 ], [ 24 ], [ 25 ], [ 26 ], [ 27 ]). However, the species is believed to avoid highly-modified areas [ 28 ] and to prefer habitats containing proportionally more native vegetation cover [ 24 ].…”

“…The puma is well documented in North America, but there is a lack of studies to provide information about the genetics and ecology of pumas in South America, especially in Brazil. It is argued that the species have only recently recolonized south and southeast regions, following decrease in logging activities after depletion of the Atlantic rainforest in the 1960s [ 27 ]. Although there are evidences that puma may act as source–sink metapopulation structure within these areas (e.g.…”

A mosaic of intact native and human-modified vegetation use can provide important habitat for top predators such as the puma (Puma concolor), avoiding negative effects on other species and ecological processes due to cascade trophic interactions. This study investigates the effects of restoration scenarios on the puma’s habitat suitability in the most developed Brazilian region (São Paulo State). Species Distribution Models incorporating restoration scenarios were developed using the species’ occurrence information to (1) map habitat suitability of pumas in São Paulo State, Southeast, Brazil; (2) test the relative contribution of environmental variables ecologically relevant to the species habitat suitability and (3) project the predicted habitat suitability to future native vegetation restoration scenarios. The Maximum Entropy algorithm was used (Test AUC of 0.84 ± 0.0228) based on seven environmental non-correlated variables and non-autocorrelated presence-only records (n = 342). The percentage of native vegetation (positive influence), elevation (positive influence) and density of roads (negative influence) were considered the most important environmental variables to the model. Model projections to restoration scenarios reflected the high positive relationship between pumas and native vegetation. These projections identified new high suitability areas for pumas (probability of presence >0.5) in highly deforested regions. High suitability areas were increased from 5.3% to 8.5% of the total State extension when the landscapes were restored for ≥ the minimum native vegetation cover rule (20%) established by the Brazilian Forest Code in private lands. This study highlights the importance of a landscape planning approach to improve the conservation outlook for pumas and other species, including not only the establishment and management of protected areas, but also the habitat restoration on private lands. Importantly, the results may inform environmental policies and land use planning in São Paulo State, Brazil.

“…Es notoria la recolonización en varias áreas de la distribución del puma, lo cual sucede con un creciente contacto con comunidades rurales, urbanas y suburbanas. Entre las interacciones que se han registrado pueden mencionarse, por ejemplo las del medio oeste de Estados Unidos (Thompson y Jenks 2010, LaRue et al, 2012 y el Sudeste de Brasil (Mazzolli 2012), y las pampas de la Provincia de Buenos Aires (Chimento & De Lucca 2014).…”

Entre los años 2013 y el 2017, siete (7) interacciones de pumas con comunidades rurales fueron registradas, cuatro (n= 4) de las cuales incluyeron ataques a animales domésticos, y donde la respuesta de la comunidad fue la persecución y muerte del puma. En los otros tres (n 3) registros, no se reportaron daños a rebaños, y los pumas fueron capturados, o por la comunidad, o por el servicio público, y translocados por el servicio público a una nueva área. A pesar del bajo número de muestras, los resultados revelan: (1) que existen casos en los que la población no elimina al felino inmediatamente sucedida la interacción, y solicitan asistencia de las autoridades; (2) aunque las autoridades reaccionan de la mejor manera posible para efectuar translocaciones, en una ocasión un puma silvestre fue enviado a un zoológico y en la otra el puma fue abatido, lo que demanda la implementación de un protocolo para ayudar a la toma de decisiones en estas situaciones. Los resultados también indicarían: (1) que los niveles de tolerancia de la población serían menores cuando hay pérdidas de rebaños domésticos; (2) que las interacciones en áreas residenciales rurales y el registro cerca del litoral desértico, zona distante de hábitats característicos de los pumas, serían indicios de una posible expansión de las poblaciones de pumas.

“…The puma (Puma concolor) is the felid with the largest distribution in America, occupying areas from southern Canada to southern Chile and Argentina (Currier 1983). In this large range, the species inhabits a wide variety of habitats (i. e., savannas, humid forests, deserts) including some periurban landscapes surrounding large cities (Mazzolli 2012;Arias-Alzate et al 2015). In the Neotropics the species is considered the main predator in mountain ecosystems, especially in areas above 2,000 masl (De Angelo et al 2009, Arias-Alzate et al 2015.…”

Even though the puma (Puma concolor) is the second largest felid in America and is widely distributed in both the continent and in Colombia. Knowledge about its food habits in many areas of the Neotropics, especially in the highlands, is still limited. We surveyed nine localities in Tamá NNP (National Natural Park) and its buffer zone monthly from June 2012 to May 2015, between 2,067 and 3,500 masl. We surveyed three linear transects of 2 to 3 km in each locality searching for scats, which were located mainly on mountain ridges. We analyzed fecal contents and estimated the minimum number of samples needed to describe puma diet, as well as the absolute frequency of records for each prey species, their relative frequency of occurrence, and biomass consumed. Potential prey species were identified using photos from camera traps at the same localities. Fecal analysis (n = 45) suggests at least eight species of medium-sized mammals as prey. Of these, three species were the most frequent, contributing 67.87 % of the biomass consumed: Nasua nasua, Mazama rufina and Cuniculus taczanowskii. The latter is a newly reported food item for the puma. No large or domestic species were recorded as part of the species' diet for the study area, in spite of its availability. Considering the potential conflict with communities surrounding the protected area, by the alleged consumption of farm animals by this and other felids, it appears that the availability of wild prey in Tamá NNP is suitable for puma and apparently the species does not need to use alternative prey as livestock. Our data suggest that the minimum number of samples required to estimate the diet in our study area varies between 31 and 41, suggesting that our results (n = 45) are a good estimate of the species' diet. This work highlights the importance of expanding the knowledge about puma foraging ecology in order to generate better conservation strategies for a species of great importance for the dynamics and stability of the Colombian Andean ecosystems. A pesar de que el puma (Puma concolor) es el segundo felino más grande en América y presenta una amplia distribución tanto en el continente como en Colombia. La información sobre los hábitos alimenticios en muchas de las áreas a nivel del Neotrópico, especialmente en zonas altas, aún es limitada. Se realizaron muestreos en nueve localidades del PNN (Parque Nacional Natural) Tamá y su zona de amortiguación mensualmente entre junio del 2012 y mayo del 2015, entre los 2,067 y 3,500 msnm. Se realizaron tres transectos lineales de entre 2 y 3 km (por cada localidad) para búsqueda de heces, las que se ubicaron principalmente sobre las crestas de las montañas. Se analizó el contenido y se estimó el número mínimo de muestras necesario para describir la dieta del Puma, la frecuencia absoluta de las presas, de ocurrencia y biomasa consumida. Las especies potenciales también se obtuvieron a través de cámaras trampa de las mismas localidades. El análisis de excretas (n = 45) indicó al menos ocho especies de mamíferos medianos com...
