To Study Blinking, a Scientist Needed a Literal Bird’s Eye View

It took a customized headpiece to monitor when and how much a grackle blinked in flight.

Source: To Study Blinking, a Scientist Needed a Literal Bird’s Eye View

 

When Jessica Yorzinski chased great-tailed grackles across a field, it wasn’t a contest to see who blinked first. But she did want the birds to blink.

Dr. Yorzinski had outfitted the grackles, which look a bit like crows but are in another family of birds, with head-mounted cameras pointing back at their faces. Like other birds, grackles blink sideways, flicking a semitransparent membrane across the eye. Recordings showed that the birds spent less time blinking during the riskiest parts of a flight. The finding was published Wednesday in Biology Letters.

Dr. Yorzinski, a sensory ecologist in the Department of Ecology and Conservation Biology at Texas A&M University, had been wondering how animals balance their need to blink with their need to get visual information about their environments.

Texas A&M researchers investigate effects of hydrology and climate on tree growth

A team of researchers from the Department of Ecology and Conservation Biology and the Department of Geography at Texas A&M University recently published research on tree growth in Biogeosciences.

Study contributors included Ajinkya Desphande, a doctoral candidate in the Department of Ecology and Conservation Biology, Thomas W. Boutton, Ph.D., Regents Professor and Sid Kyle Endowed Chair in Biogeochemistry; Ayumi Hyodo, Ph.D., research assistant professor; and Georgianne W. Moore, Ph.D., professor in Ecology and Conservation Biology and Charles W. Lafon, Ph.D. professor and assistant department head in the Department of Geography at Texas A&M University.

Deshpande and team used tree ring chronologies and stable isotopes of carbon in wood to understand how hydrology and climate affect the growth of trees in a bottomland hardwood forest.

“Bottomland hardwood forests, which are interspersed along the gulf coast, support unique floral biodiversity and have the potential to store floodwaters during major storm events and alleviate flooding risk in urban areas such as the Houston metropolis,” Deshpande said. “However, if optimum forest productivity and health is damaged during extreme droughts and floods, these important ecosystem services may be lost.”

Results indicated more favorable growing conditions and lower stress in trees growing under wetter hydrological conditions. Deshpande and colleagues concluded that management and conservation strategies dependent on site-specific conditions are critical for the health of these wetland forests under a rapidly changing hydroclimate.

“This study provides the first dendrochronological baseline for this region and a better understanding of favorable conditions for the growth and health of these forests, which can assist in management decisions such as streamflow regulation and conservation plans,” the article states.

Deshpande recently defended his thesis and will graduate from the doctoral program in Ecosystem Science and Management in December.

Feagin receives the 2020 Robert G. Dean Coastal Academic Award

Written by Justin Agan ’18

Rusty Feagin, Ph.D. recently received the Robert G. Dean Coastal Academic Award from the American Shore & Beach Preservation Association (ASBPA).

Feagin, a professor in the Department of Ecology and Conservation Biology (ECCB) and the Department of Ocean Engineering at Texas A&M University, was recently awarded the Robert G. Dean Coastal Academic Award from the American Shore & Beach Preservation Association, ASBPA. Feagin received this honor for his significant contributions to coastal science and his mentorship of the next generation of coastal scientists and engineers.

Feagin’s research centers on how living material, like plants and microflora, affect the processes of coastal erosion. He teaches classes like Coastal Processes and Ecosystem Management, Wetlands and Riverine Restoration, among others, that are attended by students from multiple different majors. 

“I enjoy mentoring grad students because its more one-on-one and it’s a bigger time investment,” Feagin said. “Over several years, you really get to know someone and what makes them tick and it gives you enough time to learn where they are strong in science and how to help them best apply themselves.”

One of Feagin’s current projects involves the building of a living shoreline by building several miles of an oyster reef in Carancahua Bay, a northern extension of Matagorda Bay on the Texas Coast, to reduce waves and decrease erosion while also increasing habitat for fish and other species in the environment.

“We’re trying to figure out ways that we can stop the erosion, but also increase the number of fish and the overall environment for fishing and hunting so that we can help the local economy,” Feagin said. 

The ASBPA, founded in 1926 to combat the effects of coastal erosion with science and lobbying for government policy change, bestows multiple special awards each year to individuals and coastal projects for their contributions to their mission. The Robert G. Dean award recognizes individuals in academia that have made significant contributions to coastal science or engineering and fostered the education of new coastal scientists or engineers. 

Feagin was nominated for this award by one of his colleagues, Cris Weber, a Senior Managing Coastal Engineer at Anchor QEA, a science and engineering firm. He also received multiple letters of support from students, former students, and other colleagues for the honor

Parker, Rogan awarded U.S. Senator Phil Gramm Fellowship

The Department of Ecology and Conservation Biology is pleased to announce that Mickey Parker and Jordan Rogan were among seven doctoral students who received a 2020 U.S. Senator Phil Gramm Doctoral Fellowship.

Texas A&M University and the Office of Graduate and Professional Studies awards this fellowship to “current doctoral students whose excellence in both research and teaching exemplifies the meaning of scholar/mentor in the highest sense,” the announcement reads.

As 2020 U.S. Senator Phil Gramm Fellows, Parker and Rogan will receive a personalized award certificate and a $5,000 fellowship.

Mickey Parker

Mickey Parker

“Receiving the U.S. Senator Phil Gramm Doctoral Fellowship is particularly meaningful for me because it recognizes both scholarly research and mentorship. Appreciation for the mentorship I’ve received throughout my career has driven my desire to guide students in achieving their goals. However, I never anticipated how large of a role that mentoring students would play in my development as a scientist. Working closely with students in the field and the classroom has undoubtedly made me a better communicator and ecologist. For me, scholarship and mentorship are tightly linked, with each informing the other. I am humbled to be recognized alongside such an accomplished group of doctoral students who have proven themselves to be consummate scholars and mentors. “

Parker is a Ph.D. candidate in the Ecology and Evolutionary Biology (EEB) Doctoral Program and an active member of the Applied Biodiversity Science (ABS) multi-disciplinary doctoral program. Parker’s dissertation research focuses on restoring populations of declining species—specifically, the dunes sagebrush lizard—through conservation translocations. He has presented research at 17 local, national and international conferences and has co-authored seven peer-reviewed journal articles, technical notes and book chapters. Over the course of his career, Parker has mentored at least 20 undergraduate students. He brings his passion for teaching aspiring biologists to the classroom, where he has been a lab instructor for three courses.

Jordan Rogan

“I am thrilled and humbled to be named one of the 2020 recipients of the U.S. Senator Phil Gramm Doctoral fellowship. Teaching and mentoring have played a large role in my graduate career thus far. Both outlets have provided unique opportunities to engage with and provide learning opportunities and guidance to a wide variety of students, the majority of whom are very passionate about science, research and learning. I have greatly enjoyed getting to know the students I have worked with, and in several cases, watching them advance into their own graduate careers or professions in the sciences and research. It has been a deeply fulfilling and impactful experience to teach and mentor students throughout my doctoral program in the Department of Ecology and Conservation Biology at Texas A&M, and I look forward to continuing my work in teaching and mentorship.”

Rogan is a Ph.D. candidate in the Department of Ecology and Conservation Biology (ECCB) and a member of the Applied Biodiversity Science (ABS) multi-disciplinary doctoral program. Her dissertation research takes a multi-disciplinary approach to assess the impact of anthropogenic land-use change on mammal biodiversity in Monteverde, Costa Rica. She has taught two different undergraduate lab courses in her department for multiple semesters, and has been a featured guest lecturer in several courses. Rogan has also served as a mentor for Texas A&M undergraduate students in ECCB and in the ABS Conservation Scholars Program funded by the National Fish and Wildlife Foundation, as well as two international students (from Costa Rica and Peru) in research analysis and as field assistants for her doctoral research in Costa Rica. She has received several awards during her time at A&M, including a Fulbright Fellowship. Rogan has actively engaged in STEM outreach in the community, and in various leadership and service roles through multiple student organizations and university committees including the entirely student-led science and research exhibition, The Ecological Integration Symposium. She will present her final thesis to the community to aid in on-the-ground, collaborative conservation initiatives.
