We encourage and support conservation-oriented field research and are happy to share the following publications about work done by field researchers at Reserva Las Gralarias. We know that only by documenting and understanding the many processes at work in nature can we hope to successfully conserve it over the long-term. Thank you to all of our field researchers for their hard work. (For a PDF version of the publication list, click here.)

Kerbs (2015) Ornitología Neotropical 26. This article documents with photographs the first cases of use as a food source of the “camacho”, a native arum found in northwestern South America. One widespread bird species and one Chocó endemic bird species were observed feeding on the fruits of the plant which is known to be a fast colonizer of disturbed areas as well as common in the wet primary forest. This plant and related species could prove to be valuable transitional plants to draw birds from nearby forest and thus aid in the regeneration of disturbed zones.
High prevalence of Batrachochytrium dendrobatidis in an Andean frog community (Reserva Las Gralarias, Ecuador). 2014. Guayasamin, Mendoza, Longo, Zamudio, and Bonaccorso. This article describes the results of a study of the fungus known as “chytrid’ which has affected frogs world-wide and was thought to be responsible for large-scale extinctions. The results found at Reserva Las Gralarias show that local species of frogs are tolerant to chytrid infection and thus raise questions about the entire theory.
