Nitrogen Fixation in Subtropical Seagrass Sediments: Seasonal Patterns in Activity in Santa Rosa Sound, Florida, USA [PDF]

Journal of Marine Science and Engineering, 2021
Seagrass beds are important coastal habitats that are diminishing globally. Nitrogen, a key nutrient, often limits seagrass growth. Nitrogen fixation provides new, bioavailable nitrogen to the plants.

Long range gene flow beyond predictions from oceanographic transport in a tropical marine foundation species [PDF]

Scientific Reports, 2023
The transport of passively dispersed organisms across tropical margins remains poorly understood. Hypotheses of oceanographic transportation potential lack testing with large scale empirical data.

Changes in the Rhizosphere Prokaryotic Community Structure of Halodule wrightii Monospecific Stands Associated to Submarine Groundwater Discharges in a Karstic Costal Area [PDF]

Microorganisms, 2023
Belowground seagrass associated microbial communities regulate biogeochemical dynamics in the surrounding sediments and influence seagrass physiology and health.

Nitrogenase Activity Associated with Halodule wrightii Roots. [PDF]

Appl Environ Microbiol, 1982
Nitrogen fixation (acetylene reduction) associated with roots of the seagrass Halodule wrightii was measured offshore near Beaufort and Moorhead City, N.C. Rates of acetylene reduction were higher in aerobic than in anaerobic assays and were linear for up to 5 days.

Assessing morphological variations in the seagrass genus Halodule (Cymodoceaceae) along the Brazilian coast through genetic analyses [PDF]

PeerJ
Background Seagrass meadows are distributed globally and provide critical ecological functions and ecosystem services, but seagrasses are still poorly studied compared with other coastal and marine foundation species.

Seagrass Halodule wrightii as a new habitat for the amphioxus Branchiostoma californiense (Cephalochordata, Branchiostomidae) in the southern Gulf of California, Mexico [PDF]

ZooKeys, 2019
The first record of the amphioxus Branchiostoma californiense on seagrass patches of Halodule wrightii in the Gulf of California is reported. Sixty individuals (19 males, 18 females, and 23 undifferentiated) were collected in May 2017 at Bahía Balandra ...

Examining Marine Assemblages Across an Inverse Salinity Gradient. [PDF]

Mol Ecol
ABSTRACT Salinity gradients and fluctuations can create a natural ecological filter, with few species tolerating salinity above 50 practical salinity units (PSUs). We investigated how an inverse salinity gradient affected marine community diversity and composition in Shark Bay, a remote hypersaline coastal embayment in Western Australia.

Pathogenicity and phylogeny of Labyrinthula spp. isolated in Washington and Oregon, USA. [PDF]

J Eukaryot Microbiol
Abstract The class Labyrinthulomycetes constitutes a multitude of species found ubiquitously in the environment, and includes pathogens of corals, hard clams, turfgrasses, and seagrasses. Labyrinthula zosterae, the causative agent of seagrass wasting disease, has been associated with declines in seagrass coverage since the 1930s.

Trait Plasticity and Warming Vulnerability in a Structurally Diverse Seagrass Ecosystem. [PDF]

Ecol Evol
Zostera capensis in Langebaan Lagoon exhibits marked spatial and seasonal variation in morphology, driven by temperature, turbidity and tidal exposure. Field results show that small‐ and large‐leaved morphotypes reflect phenotypic plasticity in response to environmental gradients, with both forms approaching their upper thermal limits under ...
