New altitudinal record for white-lipped peccary Tayassu pecari (Link, 1795) in Ecuador, with notes about activity patterns and herd size

White-lipped peccaries (Tayassu pecari) represent a key element of trophic networks in tropical rainforest ecosystems by playing the dual role of consumer and prey. Despite their importance, pressures on their populations have increased during the last few decades due to hunting and deforestation across its distributional range. These pressures may have led the remaining populations to move into new territories and to change their migratory and gregarious behaviour. In this study, we used photographic records from camera traps to collect data on biogeography of white-lipped peccaries in order to answer some questions about the demography, distribution and population size of the species in Ecuador's western Amazonia. We present new altitudinal records for the species (2,000 metres above sea level), along with some notes on herd size and activity patterns. This information is valuable for obtaining a better understanding of the species distribution and population status in order to achieve better conservation plans.
