The study uses 3D-printed robotic models to study mating behavior of the yellow toad Incilius luetkenii (formerly Bufo luetkenii). The sudden appearance of bright yellow males at the start of the wet season is a familiar phenomenon to those who have spent time in Santa Rosa. A 2015 paper with graduate student Nicolas Rehberg-Besler provided evidence that the color change facilitated sex recognition in this species. Video below and more at the link.

David’s first book on reptiles and amphibians of dry forest was my first field guide to tropical herps and I used it to pieces (literally). I hope that a new generation of dry forest naturalists enjoys this version as much as I did that one.

For those who aren’t aware of this looming challenge, I include a few (not intended comprehensive, just things I have run across in the last year) links below regarding the planned “Canal Seco.” This is an overland cargo route that would run from Limon to Cuajiniquil. Something to keep an eye on.
Much of the work sponsored by the chair will be carried out in Sector Santa Rosa of the ACG, where Dr. Melin is a long time researcher and co-director of the long-running white-faced capuchin research project. Dr. Melin’s work in Santa Rosa has focused on sensory ecology, including the consequences of primate color vision syndromes for foraging behavior.

Dr. Fedigan’s research into the white-faced capuchin monkey (Cebus capucinus) is one of the ACG’s longest running and most productive field research projects, and she has supervised dozens of students who have conducted their research in and around Santa Rosa. Her citation reads:
Linda Marie Fedigan has made enduring contributions to the study of primates, some of our closest evolutionary relatives. Canada Research Chair in Primatology and Bioanthropology at the University of Calgary, she established a world-class research station in Costa Rica’s Àrea de Conservación Guanacaste. Known for her field work, she has conducted groundbreaking long-term studies of the life history and reproductive patterns of female monkeys, which have increased our understanding of how primates adapt to their environments. An exemplary mentor, she is also known for her academic study of the role of women in science.

According to IACG’s informants, the ACG seems to have escaped Hurricane Otto relatively unscathed. Roger Blanco writes:
There really wasn’t any impact on ACG infrastructure, with the exception of some trees fallen across different roads and trails. We have been cleaning those up the last few days. Our major wok has been to support the local emergency committees with ACG staff and drivers helping to move people around, distribute water and food, help make inspections and generally reach out to the most affected communities.
Those of you plugged in to the ACG on social media will have seen many great examples of this work over the last few days as the ACG staff (as well as staff from throughout SINAC) have played a major role in the national response to this crisis.
As you may be aware, tropical storm Otto is expected to make landfall in Costa Rica, potentially as a hurricane. The projected trajectory is along the Costa Rica Nicaraguan border. At the very least ACG can expect heavy rain over the next several days so be aware of potentially bad road conditions and river crossings becoming impassable. Maria Marta has pulled some information together in the document linked below.
