Associate Professor of Biology Sophia I. Passy authored an article in The Proceedings of the National Academy of Sciences USA (PNAS) titled that showed algal coexistence in the stream benthos (the bottom-dwelling community) disobeyed the predictions of one of the most influential theories in ecology: the competition theory. For more than 80 years, this theory has asserted that in competition for one limiting resource, only one species can survive; hence the number of coexisting species equals the number of limiting resources. Numerous investigations in spatially simple communities, such as grasslands and phytoplankton, have supported the competition theory and demonstrated that the number of coexisting species is proportional to the number of resources at low supply, i.e. environmental scarcity generates biodiversity. However, Passy’s research revealed that the continental algal biodiversity in the spatially complex stream benthos was the greatest where all resources were at high supply, but steadily declined as more of them became limiting. The finding has fundamental implications for the understanding of species coexistence, which Passy showed to be dependent on community spatial organization. The patterns of coexistence and the mechanisms that govern them, as described in the paper, are pivotal for biodiversity preservation in freshwaters, such as small to mid-size streams and shallow lakes, where the algal benthos supports the entire ecosystem, including invertebrates and fish.

Forty University of Texas at Arlington undergraduate math and biology students will receive financial assistance, mentoring, seminars, research experience and specially designed course work thanks to a $780,946, five-year grant from the National Science Foundation (NSF). The grant is part of the Interdisciplinary Training Program for Undergraduates in Biology and Mathematics at the National Science Foundation, and it will support a program at UT Arlington called Undergraduate Training in Theoretical Ecology Research (UTTER).
The main objectives of the UTTER program are to enhance undergraduate education and training at the intersection of the biological and mathematical sciences, and to better prepare program scholars to pursue graduate study and careers in fields that integrate the mathematical and biological sciences. The core of the UTTER activity is jointly conducted, long-term research experiences for five interdisciplinary balanced teams of eight undergraduates from the mathematics and biology departments under extensive faculty and peer mentoring from both fields.
World renowned scholars will visit UT Arlington to interact with UTTER participants and share their expertise in research and education at the interface between biology and mathematics with the university community. The program will also enhance university student recruitment and alignment with area community colleges.
Hristo Kojouharov, associate professor of mathematics, is principal investigator for the grant and Associate Professors Doyle Hawkins and Christopher Kribs-Zaleta from the Department of Mathematics are co-principal investigators. Professor James Grover and Assistant Professor Laura Mydlarz are co-principal investigators from the Department of Biology. Associate Professor Laura Gough, from the biology department, will be a faculty associate.

James P. Grover, UT Arlington biology professor, and colleagues from Baylor and Texas A&M universities have received a $498,000 grant from the Texas Parks and Wildlife Department for a comparative study of algae on Lake Waco and Lake Granbury. More than 6 million fish have been killed since 1988 along the Brazos River due to high golden algae levels, according to Texas Parks and Wildlife. In 2007, thousands of dead fish washed up on the shores of Lake Whitney. But this was a small incident when compared to a similar event in 2005, when more than a million fish died in the lake during a three-month period. Officials believe large golden algae blooms contributed to the deaths, attacking the fishes' gills causing them to suffocate. The researchers will try to locate certain coves or "hotspots" in the lakes where conditions are optimal for golden algae growth. They will conduct laboratory experiments on the growth of golden algae and other algae occurring in these lakes. The researchers aim to evaluate manipulation of nutrients in those hotspots as a measure to reduce golden algae growth. They expect to have results in about two years.

Campbell Lab
An NSF-supported, three-year, post-doctoral fellowship is available to study herpetological diversity of Mexico at The University of Texas at Arlington. Applicants should be highly motivated, independent scientists with a sound knowledge of Neotropical herpetology. Desired qualifications include fluency in Spanish, experience conducting fieldwork under difficult conditions, photographic expertise, and leadership abilities in heading up field parties of 6 to 12 persons. Responsibilities will include organization of field trips into remote regions of Mexico for 2-4 weeks at a time, the collection and documentation of scientific materials, and identification and incorporating these materials into permanent collections. Salary is between $28,000 and $32,000. Review of applications is ongoing and will continue until a candidate is selected. The starting date is September 2007.
Applicants must have a PhD in Biology or related field. Applicants should send electronic copy of CV and names (and e-mail addresses) for two referees to:

University of Texas at Arlington Honors College Dean and Professor of Biology Dr. Robert McMahon has been named by the U.S. Department of Interior as a member of the Invasive Species Advisory Committee (ISAC), which advises the National Invasive Species Council (NISC) on matters pertaining to the biology and control of invasive species in the United States.
Dr. McMahon received his doctorate in zoology at Syracuse University and his Bachelor of Arts in Zoology at Cornell University. He has been with UT Arlington since 1972 and has authored more than 125 research and scholarly publications. His areas of research expertise include comparative physiology/physiological ecology of aquatic invertebrates; population bioenergetics/life history strategies; biology and control of macrofouling animals; freshwater and marine invertebrate zoology; molluscan biology (malacology) and biology and control of non-indigenous invasive aquatic and marine invertebrates.
ISAC is made up of 30 individuals representing a broad range of stakeholders including those in the scientific, conservation, agriculture communities, state and tribal governments and industry organizations that are impacted by invasive species.
NISC was established in February 1999 and is co-chaired by the secretaries of the Interior, Agriculture and Commerce. Its members include the secretaries of State, Defense, Transportation, Treasury, Health and Human Services, and Homeland Security and the administrators of the U.S. Environmental Protection Administration, the National Air and Space Administration, U.S. Agency for International Development and the U.S. Trade Representative.
