Fulbright Scholar arrives from Turkey
Dr. Okan Külköylüoğlu from Abant Izzet Baysal University (Bolu, Turkey) recently arrived to begin his Fulbright Fellowship at Texas State University. Dr. Külköylüoğlu is a leading expert on the taxonomy and ecology of ostracods. These are very small aquatic crustaceans in the Class Ostracoda. They inhabit a variety of aquatic ecosystems, including marine and freshwater. There are about 65,000 – 70,000 described species including extant and fossil forms. However, there are likely thousands more undescribed species. Examining samples sent to him in the past few years, Dr. Külköylüoğlu has described seven new genera from Texas. In comparison, only 52 species had previously been described for Texas. Over the next year, Okan will continue examining local samples and will no doubt discover additional new species. Okan’s host during his stay is Dr. Joe Veech whom he will be working with to learn new statistical techniques for analyzing species diversity. He will also be working closely with Dr. Benjamin Schwartz and other local scientists in his quest to discover and learn more about the diversity of this group of interesting organisms here in Texas. Okan’s wife Hati is also a biologist and has accompanied him on his visit along with their two sons, Poyraz (age 10) and Uras (age 7). We welcome Okan and his family to the department and university.

Researchers awarded funding to study endangered lizard species
Dr. Thom Hardy and Dr. Mike Forstner have been awarded a $930,000 research contract from the Texas Comptroller’s Office to conduct field surveys and develop a habitat model for the Dunes Sagebrush Lizard (Sceloporus arenicolus) in west Texas. The lizard is a candidate for endangered species listing with the United States Fish and Wildlife Service. It has primarily been threatened by habitat destruction and fragmentation. Thus there is a need to better identify the distribution of current and potential habitat and find ways of preserving that habitat. (Posted February 23, 2017)

Major funding acquired to aid in the conservation of mussels
The Texas Comptroller’s Office has dedicated $2.3 million in funds toward research on the distribution and abundance of five mussel species in basins of the Brazos, Colorado, and Guadalupe Rivers. The research will be directed by Dr. Tim Bonner, professor in the Department of Biology. In general, mussels are a highly imperiled group of species particularly in the Midwest and southeastern USA. However, much remains to be learned about the basic ecology and distribution of many species, including those in Texas. Beginning this year, Dr. Bonner and colleagues will start filling in the knowledge gaps. Their research is intended to help the United States Fish and Wildlife Service in their official assessment of the conservation status of the five species. In addition to field surveys and habitat assessments, the research will also aim to develop techniques for captive propagation. (Posted January 12, 2017)

Four undergrad students in Biology receive university research funding
Four undergrad students in the Department of Biology have been awarded funding from the university's Undergraduate Research Fund. They are Amanda Patillo (pictured to the left), Aiko Amano, Kayley Smith, and Ashley Summers. Amanda is working in the lab of Dr. Dana Garcia on a project studying how mouse eyes undergo retinomotor movements under changing light conditions. The project investigates a transporter protein that exports a chemical signal out of the retina and into the subretinal space where it can then travel to the RPE to induce pigment granule movements. Aiko is working in the lab of Dr. Noland Martin and Kayley and Ashley are both working in Dr. Shannon Weigum's lab. Congratulations to these students! (Posted December 9, 2016)

Nowlin, Team Ramp Up for EAHCP Refugia Study (Posted July 2016)
When springflows reach extremely low flows during dry weather conditions, the Edwards Aquifer Habitat Conservation Plan (EAHCP) triggers protection measures for the EAHCP covered species relying on those springs for survival. The species will be collected and placed in manmade facilities known as "refugia." The program anticipates being able to save animals for possible reintroduction back into the environment after drought of record conditions subside. An important step in implementing this program has been initiated by Dr. Weston Nowlin, Associate Professor of Biology at Texas State University. He recently briefed the EAHCP’s Science Committee on his Refugia Captive Propagation Study. Dr. Nowlin and his research team will focus their studies on the Comal Springs Riffle Beetle, Peck’s Cave Amphipod and Texas Troglobidic Water Slater, all found in and around Comal Springs. Collecting these very small creatures to study is a major challenge in itself. Nowlin said the team will use a combination of lures and nets to capture the species before bringing them back to the lab to separate them. A refugium is an artificial setting where the species can be housed when taken out of the wild. It is particularly important to be prepared when natural and human activity combine to place the habitat of the species in jeopardy. While at these refugia laboratory facilities, researchers will also study the species to expand knowledge of their biology, life histories and effective reintroduction techniques. Another aspect of the overall refugia program is the collection of endangered species known as "standing stock," which will always exist in laboratories for drought of record reasons and catastrophic events such as a large oil or fuel spill in the river. This effort provides the EAHCP the capability to reintroduce the covered species into their habitat after a catastrophic event. You can listen to an interesting interview with Dr. Nowlin at this EAHCP website link.
Tiny Beetle Big Bug on Campus in Texas State Lab (Posted July 2016)
Amid the valves, water lines, PVC, gauges, plywood and dark mesh coverings in a lab in San Marcos, several Comal Springs Riffle Beetles have settled into their new homes outside of the wild. While only about the size of strawberry seed, these tiny insects are endangered and living in the Comal Springs. Consequently, they are protected in the Edwards Aquifer Habitat Conservation Plan (EAHCP). "Essentially, we started from scratch in learning about the Comal Springs Riffle Beetle," said Dr. Weston Nowlin, biology department associate professor at Texas State University. "There was some anecdotal information about these guys, but no one had done any kind of research on this species. We are trying to learn its tolerance to varying water temperature or dissolved oxygen concentrations because low flows in the Edwards Aquifer during droughts can raise water temperature and reduce dissolved oxygen." Nowlin explained that capturing these riffle beetles in spring openings is done by putting out cloth lures, which the beetles seem to like. He said that standardizing this capture method will also help in determining whether populations of the beetles are growing or declining. The Comal Springs Riffle Beetle feeds on biofilm growing on organic matter that comes from overhanging tree leaves and wood. In the lab, they get a steady diet of decomposing leaves. Nowlin also mentioned that it took weeks to figure out which of the beetles were male and female. They are now using that new information to determine how to successfully breed them in a lab. "So, why should we care about this minuscule invertebrate? One, it is on the endangered species list outlined in our federal permit. The other notion is that the more we know about these species, the better we can manage Edwards Aquifer levels because we will know at what points the habitat in the springs begin to suffer during droughts. We think these creatures may have been around for millions of years. We need to take time to learn about them. ‘Overall, our research is off to a good start. But this is painstaking work given this beetle is so, so small.".
