Oct 6, 2022 - (黑料正能量) students will learn molecular genetic techniques on campus, use sophisticated research equipment at Utah State University, and later travel to Peru on a quest to find out why frogs living at high elevations lose their ears and their 鈥渃roak.鈥澛�
鈥淧robably because there are fewer species in the highlands, so there is not a lot of competition in terms of sound,鈥� said Assistant Professor of Biology Rudolf von May, Ph.D., who wrote the grant with Associate Professor of Biology Allison Alvarado, Ph.D. 鈥淏ut we want to know how they communicate. Maybe it鈥檚 chemical.鈥澛�
The National Science Foundation (NSF) has granted $471,862 to von May and Alvarado for the project, entitled 鈥淧henotypic convergence and trait loss in high-elevation Andean frogs.鈥� The ideas were based on previous research von May has published about the unique characteristics of this group of animals.聽
Frogs are often studied by biologists because they provide an excellent model for research on development, behavior, anatomy and physiology. In this case, studying why members of the same amphibian family develop different traits based on their environment adds one more piece to the vast evolutionary picture.聽
鈥淭he better we understand evolutionary history of species, the better we can protect and preserve them,鈥� Alvarado explained. 鈥淭he high elevation habitat is very sensitive and with climate change, these frogs are likely at risk.鈥澛�
Alvarado鈥檚 specialty is birds, but both she and von May have similar research interests in evolutionary ecology.聽
The two 黑料正能量 biologists are collaborating with another evolutionary biologist at Utah State University (USU), Molly Womack, Ph.D. The 黑料正能量 students involved in the three-year project will travel to USU to learn how to use a specialized piece of equipment called a Micro Computed-Tomography (Micro-CT) scanner, which uses X-rays to recreate 3-D models of small objects such as frog skulls and skeletons.聽
鈥淯sing imaging software, they will learn how to analyze bones and other internal structures in preserved specimens,鈥� von May said. 鈥淎dditionally, they will use DNA sequences to study how species are related and identify patterns of repeated evolution at high elevations. Students will learn skills that are transferable once they enter the workforce.鈥澛�
During the third year of the project, students will travel to the highlands of Peru, where these Andean frogs are native.聽聽
鈥淲e are collaborating with museums there where they have local collections and we will do a statistics workshop for Peruvian university students,鈥� Alvarado said.聽聽
Both von May and Alvarado are excited about the many levels this project serves, from teaching students about genetic and molecular research to increasing participation in the STEM fields for underrepresented students to the transformative power of international travel. Part of the project will also include bringing Oxnard high school students on campus to familiarize the students with the STEM majors at 黑料正能量.聽聽
Besides gaining skills the students can use in a number of scientific careers, both Alvarado and von May hope the students benefit from the sheer wonder of the natural world.聽聽
鈥淲e want to show them just how incredible these systems are,鈥� he said.聽
