Hábitos alimentarios del Puma concolor (Carnivora: Felidae) en el Parque Nacional Natural Puracé, Colombia
Neotropical puma (Puma concolor) diet is scarcely known, in particular that of mountain dwelling individuals from Northern South America. This is the first study on pumas from the paramo and the first puma diet analysis for Colombia. The puma diet was studied from 2007 to 2009 in the Puracé National...

Neotropical puma (Puma concolor) diet is scarcely known, in particular that of mountain dwelling individuals from Northern South America. This is the first study on pumas from the paramo and the first puma diet analysis for Colombia. The puma diet was studied from 2007 to 2009 in the Puracé National Park in the South Colombian Andes. Paramos are unique neotropical high altitude ecosystems which store and regulate water, and are currently threatened by agricultural expansion and climate change. Seven latrines were monitored for three years and scat collected, washed and dried. Items in scat such as hair, bones, claws and others were separated. Hairs were inspected by microscopy and compared to voucher hair museum specimens. Bone fragments, claws and teeth were also compared to museum collections and identified wherever possible. Additionally, six cameras were set along game trails to document puma and potential prey presence in the area. Food items from five species were identified in 60 puma scats; Northern Pudu (Pudu mephistophiles) was the most important prey in their diet. A total of 354 camera trap-nights photographed a male and female puma, Northern pudu and Spectacled bear (Tremarctos ornatus). The main conclusion suggests a strong dependence of puma on the threatened and mysterious Northern Pudu in paramo habitats. This behavior might reflect restricted prey availability in the high Andes mountains of Colombia, and highlights the plasticity in the puma diet. Conservation actions in the paramo should thus, focus on focal wild species, and in particularly those that show a relationship, such as the one evidenced here with the dependence of puma on Northern Pudu. These findings contribute to increase the little known ecology of Andean puma populations and the species as a whole in Colombia. Baseline data on puma prey populations in different ecosystems throughout their range, is critical to understand the regional requirements for survival, and design conservation actions, to follow and evaluate the need for particular protected areas along their geographical gradients. |

We the aim to contribute with conservation strategies, we used line transects (distance method) to estimate the population density of the river dolphin, S. guianensis, in the estuarine region of Cananéia, Southeastern Brazil. The study, developed from May 2003 until April 2004, dur-ing dry and rainy seasons and different times of the day, included a sampling area divided into three sectors according to their proximity to the open sea: Sector I (the closest to the open sea); Sector II (with a large flow of fresh water and a salient declivity); and Sector III (with a large flow of fresh water and non salient declivity). Onboard random sampling was carried out in all three sectors, and dolphins seen from the bow to 90° on both port and starboard sides, were registered along with their position and distance from the boat. The total density found was 12.41ind/km² (CV=25.53%) with an average of 2.2 individuals per group for both periods of the day, morning and afternoon. Densities also varied between dry and rainy seasons, being lower in the first with 5.77ind/km² (CV=27.87%) than in the second 20.28ind/km² (CV=31.95%), respectively. Regarding the three sectors, a non-causal heterogeneous distribution was found: Sector I was the most populated (D=33.10ind/km², CV=13.34%), followed by Sector II (D=7.8ind/km², CV=21.07%) and Sector III (D=3.04ind/km², CV=34.04%). The aforementioned area, due to its proximity to the open sea, has the highest salinity level and therefore has the greatest chance of holding most of the marine fish schools which can be cornered by dolphins on high declivity areas during fishing activities. This suggests that food availability may be the most important factor on the river dolphin’s distribution in the estuary. Similar studies will contribute to a better understanding of these populations and are essential for future conservation strategies.
