Dybiec Selected for NOAA's Margaret A. Davidson Fellowship

5/20/2022

Comments

 
Congratulations to Jake Dybiec on being selected for the 2022-2024 cohort of NOAA's Margaret A. Davidson Graduate Fellowships. As part of the program's second class, Jake joins other graduate students from around the country who will be conducting timely research at National Estuarine Research Reserves. Jake's project will investigate the interactive effects of nutrient enrichment and wave action on marsh resilience at the Weeks Bay NERR.

UA Presentations on Marsh Restoration at JASM 2022

5/16/2022

Comments

 
Drs. Julia Cherry, Shelby Rinehart, and Behzad Mortazivi, as well as grad students Emily Fromenthal and Jacob Dybiec, presented talks in a session on coastal wetland restoration and management in the Anthropocene at the Joint Aquatic Sciences Meeting in Grand Rapids, MI. These talks provided overviews of our research on the recovery of carbon storage and nitrogen removal in restored marshes of the MS-AL Gulf Coast, using those data to develop a metric-based model of functional recovery, comparisons of insect communities in created and natural tidal marshes, and the effects of burrowing crabs on marsh sediments.

New Paper on Surface Elevation Change at Grand Bay NERR

Salt panne and marsh habitat at Grand Bay NERR
A new collaborative paper on surface elevation change and accretion at Grand Bay was published today in Wetlands Ecology and Management. As part of the project, we examined patterns of change at five sites spanning the coastal elevation gradient, including low marsh dominated by Spartina alternflora, mid-marsh dominated by Juncus roemerianus, mid-elevation salt pannes, and high marsh dominated by Cladium jamaicense. We then compared them to rates of water-level rise for the region. Results from this study suggest that the Juncus marshes higher in the tidal frame are the most vulnerable to sea-level rise.

Jake wins best oral presentation award.
Congratulations to Jake Dybiec, a Ph.D. student in the Cherry Lab! He was recognized for giving the best oral presentation at the 2022 Mississippi Water Resources Conference, which was held in Starkville, MS on April 12-14th. Jake used data collected as part of our Sea Grant project to develop a preliminary metric-based indicator of functional recovery in restored tidal marshes of the Mississippi-Alabama Gulf Coast.

Cherry Lab Members Present at CERF 2021 Conference

Multiple members of the Cherry lab presented their research at the CERF virtual conference this week. Dr. Cherry (on behalf of former grad student Erin Smyth) and Taylor Ledford, a graduate student in the Mortazavi lab, presented back-to-back anchor talks in the Coastal Restoration: Challenges, Successes and Innovations Session. They presented on projects examining the recovery of ecosystem functions in constructed marshes, which were conducted as part of the CRIMSON project.  Dr. Shelby Rinehart, a postdoc in the Cherry lab, and graduate students, Jake Dybiec and Emily Fromenthal, also presented posters on their CRIMSON research. Their posters examined burrowing crab impacts on marsh soils, sediment flux dynamics, and shifts in insect functional groups in natural and constructed marshes along the Fowl River in Alabama.

New Paper Examines Impacts of Nutrient Enrichment on Mangrove Cays in Belize

10/13/2021

Comments

 
A new paper by Simpson and others, published this week in Oecologia, details changes in mangrove cay size over time, as well as differences in forest structure and hydro-edaphic characteristics of paired cays with and without bird rookeries. Rookeries represent a potential source of nutrient inputs to mangrove systems that can serve as a proxy for increases in anthropogenic nutrient loading to coastal ecosystems. Cays with bird rookeries disappeared 13 times faster than those without birds, and these losses corresponded with lower soil organic matter, lower soil total nitrogen and carbon content, greater aboveground biomass, and greater leaf nitrogen concentration on rookery cays. Collectively, these results suggest that nutrient enrichment may reduce ecosystem stability and accelerate cay loss.

Cherry and Mortazavi Present Restoration Research at ALWRC

Drs. Cherry and Mortazavi both presented aspects of their collaborative research comparing ecosystem functions in natural and constructed wetlands at this week's Alabama Water Resources Conference. Mortazavi presented on the the recovery of nitrogen removal capacity in two constructed marshes along the Fowl River in Alabama, while Cherry presented on the recovery of carbon storage capacity in those same wetlands. Theses studies were carried out by a team of graduate students and postdocs in the Cherry and Mortazavi labs as part of the ongoing CRIMSON project.

Dybiec and Fromenthal Awarded SWS Research Grants

Congratulations to Jake Dybiec (Ph.D. student) and Emily Fromenthal (M.S. student), both of whom received student research grants from the Society of Wetland Scientists to support their graduate research. Jake's project examines the role of sedimentation in mediating the outcomes of competition between Spartina alterniflora and Juncus roemerianus​, and Emily's project compares insect communities between natural and restored marshes, with a focus on pollinators.

New Publication on Ecosystem Functions in Natural and Restored Marshes

5/28/2021

Comments

 
A second paper on research at our Fowl River marsh sites has been published in Restoration Ecology. In this study, Ledford et al. compared carbon fluxes and nitrogen removal rates between one natural and two constructed tidal marshes. Porewater ammonium, gross ecosystem productivity (GEP), ecosystem respiration, denitrification, and DNRA were similar among the three marshes, with the exception of greater denitrification in one of the two constructed sites. These results suggest that marsh restoration did recover some ecosystem functions in these 33-year-old constructed marshes.

Cherry Lab Welcomes New Postdoc

3/1/2021

Comments

 
We are excited to welcome Dr. Shelby Rinehart to the lab as a postdoctoral researcher. After earning his Ph.D. from the San Diego State University and University of California Davis Joint Doctoral Program in Ecology in 2018, Shelby was a scientific advisor for Westlands Water District in California and a Zuckerman Postdoctoral Fellow at the Hebrew University of Jerusalem in Israel. Shelby’s current research interests focus largely on understanding how trophic diversity affects ecosystem function under changing climates, and how consumer functional traits, like foraging strategy, may help predict the outcomes of these interactions.
