The southern temperate forest of Chile and Argentina is a unique ecosystem, which is home to a great diversity of plant and animal species that are unique in the world. Unfortunately, these environments are highly impacted by human activity.The austral temperate forest of Chile and Argentina is a very unique ecosystem, which holds a large number of endemic plants and animals. Unfortunately, these environments are highly threatened due to human activity.

The system

We studied the spatial and temporal dynamics at the landscape level of three species of endemic frogs (Darwin's frog, rosy leaf litter frog, and spotted frog) infected with the chytrid fungus (Batrachochytrium dendrobatidis). This fungus produces chytridiomycosis, an emerging infectious disease in Chile and various regions of the world.We study the spatio-temporal dynamics, at the landscape level, of three endemic frogs (Darwin's frog, rosy ground frog, gray wood frog) infected with the chytrid fungus (Batrachochytrium dendrobatidis). This fungus causes the chytridiomycosis, an emerging infectious disease in Chile and several regions of the world.

This is an applied ecology project, where we will propose recommendations that can be used by those responsible for managing and creating conservation policies to ensure the persistence of metapopulations of wood anurans, even in the presence of chytridiomycosis.This is an applied project where we will provide recommendations that can be understood and used by conservation practitioners and policy makers in order to ensure the persistence of metapopulations of forest anurans even under the presence of recurrent chytridiomycosis.

To study the metapopulation dynamics of three endemic amphibians of the southern temperate forest. Study the metapopulation dynamics of three amphibians endemic to the austral temperate forest.

1.

Understand the spatio-temporal dynamics of the chytrid fungus in Darwin's frog metapopulations, and the influence of possible reservoirs on this process.Understand the spatio-temporal dynamics of the chytrid fungus within Darwin's frog metapopulations, and the role of potential chytrid reservoirs over this process.

2.

To test the effectiveness of a mitigation measure against chytridiomycosis (exclusions) in Darwin's frog populations.Trial a mitigation action against chytridiomycosis (exclusionary fences) in wild Darwin's frog populations.

3.

Design guidelines for population and epidemiological management of Darwin's frog metapopulations.Design guidelines to assist the population and epidemiological management of Darwin's frog metapopulations.
