Dr. Ryan King, Department of Biology, Baylor University, will join several other investigators on a John Wesley Powell Center for Analysis and Synthesis Working Group, "Analyses of contaminant effects in freshwater systems: synthesizing abiotic and biotic stream datasets for long-term ecological research."
The objective will be to synthesize the >20 years of standardized hydrological, chemical, and ecological samples collected from streams and rivers across the U.S. to investigate how human activities have influenced stream ecosystems.
Stephen Cook successfully defended his dissertation, "Spatiotemporal Examination of Benthic Algal and Macroinvertebrate Assemblage Structure Across a Gradient of Phosphorus Enrichment" in May 2019 and officially graduated on August 19th, 2019 with a PhD in Biology. Congratulations, Stephen!
Stephen Cook's first publication, which was published in Ecology, has been recognized as one of the most downloaded in 2018. Ecology is the flagship journal of the Ecological Society of America and recognized as one of the top journals in the field.
Moncie Wright successfully defended her dissertation "Interactions Between Titanium Dioxide Nanoparticle Exposure and Grazing Organisms on Periphyton Biomass and Community Composition" and graduated with the Doctor of Philosophy degree in Biology from Baylor University on Saturday, December 15, 2018, in the Ferrell Center, Waco, Texas.
Caleb Robbins successfully defended his dissertation, "From Landscapes to Streams: The Pattern and Function of Labile Dissolved Organic Carbon" in July 2018. Caleb graduated with the Doctor of Philosophy degree in Biology from Baylor University on August 11, 2018, in the Ferrell Center, Waco, Texas.
Brittany Perrotta coauthored two high-impact papers in 2018: "Engineered nanoparticles interact with nutrients to intensify eutrophication in a wetland ecosystem experiment", published in Ecological Applications and "Size-Based Differential Transport, Uptake, and Mass Distribution of CeO2 Nanoparticles in Wetland Mesocosms", published in Environmental Science & Technology. Way to go, Brittany!
Dan Hiatt published his 2nd dissertation chapter entitled "Effects of stream velocity and phosphorus concentrations on alkaline phosphatase activity and carbon:phosphorus ratios in periphyton" in the journal Hydrobiologia. Dan is in the home stretch, just wrapping up that last chapter. Go Dan, go!
Stephen Cook, a Ph.D. student in the Aquatic Ecology Lab, received news that his first paper, "Freshwater eutrophication sharply reduces temporal beta diversity," will be published in Ecology, the flagship journal of the Ecological Society of America. Congratulations, Stephen!
Moncie Wright published the first chapter of her dissertation in Science of the Total Environment, a journal with an impact factor of 5.0 (which is very good). The title of her paper is "Titanium dioxide nanoparticle exposure reduces algal biomass and alters algal assemblage composition in wastewater effluent-dominated stream mesocosms." Two other chapters are close to submission. Congrats, Moncie!
TITAN has been updated on CRAN (the R comprehensive archive network) and can be installed using one of dozens of CRAN mirrors from anywhere in the world. TITAN has been applied in ~140 studies since it was first published in 2010, with more users every year. This update is intended to make diagnostics more straightforward in addition to faster processing times.
King and his lab group will be funded for at least a second year to study the effects of headwater streams on downstream ecosystems in Alaska. The award, from the Alaska State Wildlife Fund and US FWS, totals $98,700 for fiscal year 2018.
Dan Hiatt and Caleb Robbins, both PhD candidates in the Aquatic Ecology lab, published their study showing that alder, an upland shrub with N-fixing bacterial symbionts, generates so much excess N at the catchment scale that it controls N2-fixation in boreal streams of Alaska.
For more than three decades a legal dispute raged between Oklahoma and Arkansas over acceptable phosphorus levels in the scenic waterways along the Illinois River. The issue eventually reached the U.S. Supreme Court in 1992. Now, a three-year study conducted by Baylor biology professor Ryan S. King recently helped settle the long-standing dispute.
WACO, Texas (April 3, 2014) -- Ryan S. King, associate professor of biology in Baylor’s College of Arts and Sciences, was awarded a $600,000 grant to estimate the appropriate phosphorus level in the Illinois River and nearby rivers and streams and help settle an on-going legal dispute between Oklahoma and Arkansas that reached all the way to the Supreme Court in 1992.
The Illinois River, a tributary of the Arkansas River, runs for 145 miles through Arkansas and Oklahoma. For decades, the two states have fought over pollution in the river, with Oklahoma blaming Arkansas for polluting the river with elevated phosphorus from municipal waste water and poultry fertilizers, which leads to an increase in algae growth. …
