The permanent presence of Las Nubes in the Alexander Skutch Biological Corridor and its ongoing relationship with local and regional communities and stakeholders give us a privileged position to carry out long-term research.

Las Nubes supports student research through research grants and promotes Faculty research projects in collaboration with partners outside York University. Research emphasis has been interdisciplinary and often action-oriented, including on establishing the current status of the biological populations in the area, as well as promoting sustainable land management practices, exploring options of rural community tourism, arts-based research on social-environmental relations, and corroborating links between different land uses and biodiversity richness, such as the important link between a multilayered and diversified shade coffee canopy and avian migratory habitat, among others. others.

Mammal Monitoring Project

This project continues to generate much valuable information about biodiversity in the region, including the confirmation (and amazing photographs) of at least 13 species of mammals, including armadillos, wild boars, ant-eaters, white-collared peccaries, coyotes, ocelots, pumas (mountain lion) and the endangered river otter among others in the biological corridor. This project has already provided evidence of the presence of endangered species in the corridor, key information that continues to confirm the vital importance that the corridor and its ecological connectivity has for species conservation.

With the SINAC, MINAE & Tropical Science Centre, we currently have 8 cameras in the Alexander Skutch Biological Corridor. The following are some of the images captured by our cameras:


Amphibians and Reptiles Project

This project emerged as an attempt to identify and locate the so-called ‘lost amphibians’ or those species that have disappeared from the scientific radar from a significant amount of time (sometimes decades). In 2016, the then MES student Andrés Jiménez Monge, initiated in conjunction with Dr. Felipe Montoya a database of amphibians and reptiles found in the ASBC.

This initiative was born after encountering a particular species (Atelopus various) during a walk with students during the Las Nubes field course. Since then, several endemic and endangered species of amphibians and reptiles have been spotted by local communities in ASBC. The development of this focal citizen science project can help track endangered species populations whilst creating new meanings within the community in order to support the conservation.

The Alexander Skutch Biological Corridor (ASBC) is an Ark (ARCA in Spanish) of biodiversity, with abundant plants and invertebrates, over 300 species of birds and a great variety of mammals.

ASBC is also a preferred space for amphibians and reptiles. We invite you to participate in ARCA, sharing your photographs (On our facebook page). With this, we are creating an inventory of amphibians and reptiles (frogs, toads, salamanders, lizards, caecilians, iguanas, snakes, turtles) found in ASBC, and at the same time will work on the education and protection of these species.


Ecology of Plant-Hummingbird Interactions

Led by Catherine Graham of the Swiss Federal Research Institute with the support of the European Research Council, and in Costa Rica by María Alejandra Maglianesi of the State Distance University (UNED), this project seeks to determine how the interactions between plants and hummingbirds vary at different elevations. The project area extends from 700 m to 3,000 m a.s.l. in the Cordillera de Talamanca, which is the most extensive mountain range in Costa Rica. Within this gradient in the south-central area of ​​the country, there are four altitudinal bands with three sites in each one, for a total of 12 sites distributed from Cerro de la Muerte to Pérez Zeledón. The Las Nubes Biological Reserve is one of the study sites. To collect the project data, the visits that the hummingbirds make to the plants are observed, the flowers they feed on are counted, and the hummingbird species are noted. These data are collected along a 1.5 km transect at each study site and interactions are recorded using time-lapse cameras. Read the latest report

Ecology of Plant-Hummingbird Interactions (EPHI) Project


The Fisher Fund for Neotropical Conservation supports a wide range of research projects which focus on issues such as tropical deforestation, sustainable development, and biodiversity conservation.
