Population monitoring of the long lost and thought extinct Tandayapa Andean Toad (Rhaebo olallai) in Northwest Equador.

» Read Progress Reports

Discovered nearly 50 years ago, the Tandayapa Andean Toad is one of the rarest anuran species in western Ecuador. Since 2014, hundreds of search hours have been spent trying to locate living individuals – all without success. But in 2012, Ryan's team discovered a small population in northwest Ecuador.

Understanding the geographic distribution of any species is critical to conservation efforts. Team Lynch will set out and deploy several Song Meter SM4 acoustic recorders in the remote and rugged area of the Rio Manduriacu Reserve to determine the geographic extent of the only known living population of the Tandayapa Andean Toad and identify other potential populations. The Song Meter SM4s will allow his team to better determine the extent of this population and increase the group's ability to detect species across the landscape in a resource-efficient manner.

The project will have an immediate and profound impact on the conservation of a species that is on the brink of extinction. To that end, the data collected by the Song Meters will be analyzed using Kaleidoscope Pro with its new acoustic Cluster Analysis. The results will be shared with the global research and conservation communities.

Texas Pollinator PowWow Bat Education.

» Read Progress Reports

Dr. Comer is a professor of Forest and Wildlife Management in the Arthur Temple College of Forestry and Agriculture at Stephen F. Austin State University. He teaches roughly 200 undergraduates each year and incorporates extensive field-based, hands-on learning opportunities addressing a variety of wildlife research and management techniques, including acoustic monitoring.

Working in conjunction with the Texas Pollinator PowWow of Nacogdoces, Christopher will be using iPad-powered Echo Meter Touch bat detectors to lead almost 300 bat walk participants in a spring time, guided night hike while acoustically identifying bats. This large-scale education and outreach project is designed to increase the awareness of bat ecology and bat conservation among attendees of current and future PowWows. Just as important, the acoustic data will determine a baseline species occurrence list for public conservation properties in the area. The equipment will also be used in support of research projects examining the relationships between bat occurrence and various vegetation characteristics in forested communities.

Escape from deadly disease: Can environmental refugia save tropical mountain frogs from extinction?

» Read Progress Reports

The eastern slopes of the Andes Mountains is home to the world's largest diversity of frog species, but many threatened species have suffered populations collapses because of the fungal disease, chytridiomycosis.

Dr. Catenazzi will use Song Meter acoustic recorders and Kaleidoscope Pro software to collect and analyze frog vocalization data covering six threatened species listed on the IUCN Red list. The results will be used to locate environmental refugia where frogs that are highly susceptible to chytridiomycosis can persist. Discoveries of surviving populations will be shared with governmental and non-governmental organizations to guide future conservation efforts. Alessandro's team will use the data to improve Red List assessments for species affected by this deadly fungus.

Alessandro will share his findings in peer-reviewed scientific publications, social media and a blog featured by AmphibiaWeb.
