Why is this Spartina falling down?

Yesterday, while surveying a brackish marsh restoration site near Port Arthur, Texas, we noticed that some of the planted Spartina alterniflora appeared to be falling down (left), especially around the edges of constructed mounds. Although the plants grew quickly (they are only about a year old!), is erosion around the edges of the mound going to undermine the long term success of these plantings? We noticed that mounds with fill added so that the sides are less steep seemed to have more upright plants (below). These shallower areas, however, had extensive cyanobacterial mats (green mats in the water in the picture below). What are the impacts of dense cyanobacterial mats on the animals in this system?

Postdoc and grad student positions

Postdoctoral Researcher: Wetland Restoration Ecology

Department of Marine Biology, Texas A&M University at Galveston

A postdoctoral researcher position is available to work with Dr. Anna Armitage and Dr. Antonietta Quigg in the Department of Marine Biology at Texas A&M University in Galveston. The associate will take a leadership role with a two-year project assessing the effects of landscape engineering (e.g., sediment source, hydrology) on restored brackish marsh ecological functions. Possible research fields include patterns of productivity, carbon sequestration, and the development of food webs in restored marshes.

Required qualifications: Ph.D. or equivalent in Biology, Ecology, or related field.

Additional qualifications desired: Experience with field ecology methodologies, community ecology, use of stable isotopes, productivity measurements; strong writing skills.

Special requirements: Physical ability to conduct research in the hot and humid conditions typical of Gulf of Mexico coastal wetlands.

Responsibilities: The associate will be expected to conduct independent research, provide some assistance to graduate students, write research articles, and generate reports for the funding agency.

Start date is September 1, 2008. For full consideration, submit applications by July 1, 2008. Submit TAMU application, statement of interest and experience, and CV at the online submission website, tamujobs.tamu.edu (NOV# 081262). In addition, please have three references submit letters of recommendation directly to Dr. Anna Armitage (armitaga@tamug.edu) with a cc to Betty Thompson (thomspob@tamug.edu).

Graduate student: Wetland Restoration Ecology

Department of Marine Biology, Texas A&M University at Galveston

We are seeking a M.S. or Ph.D. student to participate in a two-year project assessing the effects of landscape engineering (e.g., sediment source, hydrology) on restored brackish marsh ecological functions. Possible research fields include patterns of productivity, carbon sequestration, and the development of food webs in restored marshes.

Required qualifications: B.S. or equivalent in Biology, Ecology, or related field.

Additional qualifications desired: Relevant coursework or experience with field ecology methodologies, community ecology, use of stable isotopes, productivity measurements; strong writing skills.

Special requirements: Physical ability to conduct research in the harsh heat and humidity typical of Gulf of Mexico coastal wetlands.

Responsibilities: The graduate student will be expected to conduct independent research and assist with generating reports for the funding agency.

Desired start date is Spring 2009. Application deadline is July 2, 2008 or until a candidate is selected. Send statement of interest and experience, CV, unofficial transcripts, GRE scores (if available), and three letters of reference in electronic format to Dr. Antonietta Quigg (quigga@tamug.edu).
