“…Andean bears (also known as spectacled bears, in Spanish osos de anteojos or osos andinos) are the only bear species in South America and the last surviving lineage of the subfamily Tremarctinae (García-Rangel 2012). Andean bears are a relatively under-studied species (Falconi et al 2020), especially among charismatic megafauna. However, evidence has been accumulating that the species has experienced population declines over the last several decades; the International Union for the Conservation of Nature classifies Andean bears as vulnerable to extinction (Velez-Liendo and García-Rangel 2017).…”

“…En el Perú, algunos de los grandes desafíos que enfrenta la protección del oso andino es la poca información sobre registros de su presencia e interacción con el hombre, en especial, en zonas rurales aisladas y de difícil acceso, como algunas observadas en el departamento de Ayacucho (Cossios et al 2012, Figueroa & Stucchi 2013, Serfor 2016, Falconi 2020. Así, el primer registro documentado del oso andino en Ayacucho data de hace más de 40 años en la provincia de Huanta (Peyton 1980) y, posteriormente, luego de 15 años en la provincia de La Mar mediante entrevista (Pacheco et al 2007).…”

En el presente estudio se determina la presencia del oso andino Tremarctos ornatus y su interacción con el humano en tres territorios comunales de la provincia de La Mar (Ayacucho). Entre setiembre y octubre de 2019, establecimos un total de 22 transectos para identificar rastros de la especie, entrevistamos a la población sobre su interacción con el oso y, finalmente, inspeccionamos cadáveres de ganado cuyas muertes fueron atribuidas a ataques de la especie. En total se registraron 312 rastros de oso andino, la mayoria restos de alimentos, hallados predominantemente en las zonas de puna mas arriba que los bosques montanos. Los pobladores locales conocen y tienen encuentros con el oso andino en campo e identificaron como las amenazas más recurrentes para el oso los incendios de pastizales, la extracción de madera y la ganadería. Además, informan que los osos causan daños a los cultivos y al ganado. No obstante, no se encontraron suficientes evidencias para confirmar que el oso andino hubiese atacado a alguno de los siete cadáveres de ganado evaluados, pero sí se identifico una posible manipulación o consumo en uno de estos. Nuestros resultados resaltan la importancia de combinar muestreos de presencia del oso con observaciones de la población para identificar amenazas y reducir potenciales conflictos humano-oso basado en eventos no completamente confirmados.

“…However, studies that seek movement data are notoriously expensive and even high-quality occurrence data are limited for most species. Andean bears (Tremarctos ornatus)-the only extant ursid in South America-are one such example of a data-poor species (Cáceres-Martínez et al 2020;Falconi et al 2020). This is particularly true within the country of Colombia where many regional environmental authorities have neither the time nor the nancial resources to carry out research on Andean bears yet are responsible for implementing conservation programs for the species within their jurisdictions (Velásquez Durán 2018).…”

Context Conserving or restoring connectivity is a common objective of landscape-scale conservation initiatives. However, precise species occurrence or movement data to inform or validate spatial models are often lacking.Objectives Our objectives were to 1) produce the rst approximation of country-wide connectivity for Andean bears ( Tremarctos ornatus ) in Colombia and 2) demonstrate a novel approach for model validation which uses publicly available web and social media records of a agship species.Methods We used general knowledge about Andean bear habitat associations and indices of ecological integrity to construct a resistance surface across the Colombian Andes. We used this resistance surface to model omnidirectional connectivity using circuit theory. We validated our model with coarse location data acquired from local news stories and social media posts.Results Our model was most sensitive to changes in the resistance values of agricultural landcover and the mid-elevational zone, but uncertainty analysis demonstrated these had little impact on our conclusions regarding the municipalities most conducive to Andean bear movement. Just over one-third of those areas most conducive to Andean bear movement were within protected areas, while 8% coincided with agricultural landcover.Conclusions We constructed a model of connectivity that did not rely on independent, empirically derived location data. Our model is coarse (1 km resolution) but can still provide useful information to practitioners in Colombia who are working with scarce ecological data. More information about how Andean bears move through agricultural landscapes would help improve our understanding of connectivity for this species in Colombia.
