If you have any feedback on how we can make our new website better please do contact us. We would like to hear from you. 


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.

  • Patterns of parental care in Neotropical glassfrogs: fieldwork alters hypotheses of sex-role evolution. 2017. Delia, Bravo-Valencia and Warkentin. This lengthy paper analyzes the role of male and female adult glassfrogs in providing care for egg masses and hypothesizes some changes in current theories of glassfrog evolution.

  • The Natural History, Distribution, and Conservation of Lonely Rainfrogs, Pristimantis eremitus. 2016. Hutter, Liu, Kell, Lyons and Guayasamin. This paper details the results of a 13-month study of the Lonely Rainfrog at Reserva Las Gralarias.

  • Macroinvertebrate community composition, food web structure, and emergence rate of Neotropical cloud-forest streams in Mindo, Ecuador. 2016. Harris, A. Thesis for MSc. Grand Valley State University.

  • Cryptic diversity concealed in the Andean cloud forests: two new species of rainfrogs (Pristimantis) uncovered by molecular and bioacoustics data. 2015. Hutter and Guayasamin. This paper describes two new species split from Pristimantis calcarulatus, one based on field work at Reserva Las Gralarias.

  • Phenotypic plasticity raises questions for taxonomically important traits: a remarkable new Andean rainfrog (Pristimantis) with the ability to change skin texture. 2015. Guayasamin, Krynak, Krynak, Culebras and Hutter. This paper describes a new species of frog discovered by Kathy and Tim Krynak at Reserva Las Gralarias which was found to change its skin texture within minutes from spiny to smooth, the first known vertebrate to have such an ability and which raises questions about the currently accepted taxonomy of frogs.

  • Amphibian conservation (Centrolenidae) in neotropical cloud-forest streams using stable isotopes to measure energy subsidies. 2015. Harris, Rios-Touma, Encalada and Snyder. This is a presented poster based on MSc field work at Reserva Las Gralarias.

  • Xanthosoma undipes (Araceae) as a food source for Black-chinned Mountain-Tanager (Anisognathus notabilis) and Orange-bellied Euphonia (Euphonia xanthogaster) in Northwest Ecuador. 2015. Kerbs. Ornitología Neotropical 26. This paper documents with photographs the first cases of use as a food source of the “camacho”, a native arum found in northwestern South America.

  • High prevalence of Batrachochytrium dendrobatidis in an Andean frog community (Reserva Las Gralarias, Ecuador). 2014. Guayasamin, Mendoza, Longo, Zamudio, and Bonaccorso. This paper describes the results of a study of the fungus known as “amphibian 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.

  • Physical habitat, macroinvertebrate community structure, and stream metabolism in the headwaters of an Ecuadorian cloud forest stream network. 2014. Snyder, Harris and Lyons. This is a presented poster based on MSc field work at Reserva Las Gralarias.

  • The territoriality, vocalizations and aggressive interactions of the red-spotted glassfrog, Nymphargus grandisonae, Cochran and Goin, 1970 (Anura: Centrolenidae). 2013. Hutter, Escobar-Lasso, Rojas-Morales, Gutiérrez-Cárdenas, Imba, Guayasamin. This paper describes the calls and various aspects of behavior of the red-spotted glassfrog from Reserva Las Gralarias, Mindo, Ecuador and from Manizales, Caldas, Colombia.

  • Applications of geographic information systems and remote sensing techniques to conservation of amphibian habitats in Northwestern Ecuador. 2013. Palacios, M. Thesis for MSc. Universidad Tecnológica Iberoamericana.

  • Evaluate the Phylogenetic and Morphological Diversity of the Hummingbird Community: How does this diversity change over the elevation gradient? Initial project report 2012 Weinstein.

  • A new cryptic species of glassfrog (Centrolenidae: Nymphargus) from Reserva Las Gralarias, Ecuador. Hutter and Guayasamin. 2012. This paper describes a new species of glassfrog Nymphargus lasgralarias discovered at Reserva Las Gralarias in 2011.

  • Hyloscirtus criptico etc description pdf,   Coloma et al. 2012. This is a lengthy monograph with species description of the new species of glass frog Hyloscirtus criptico that was discovered at Reserva Las Gralarias in 2011 as well as the species description of Hyloscirtus princecharlesi and a review of the molecular phylogenetics of stream treefrogs.
