Sediment-effects on seagrass Zostera muelleri in New Zealand
… to determine sediment effects on the seagrass Zostera muelleri in terms of light attenuation and substrate physico-chemical alteration. Within this research framework, provision of assistance for successful seagrass restoration was also considered. The principal research question for this …

Ecology and ecophysiology of Zostera capensis: responses and acclimation to temperature
… of the threatened, habitat-forming seagrass, Zostera capensis in Langebaan Lagoon, a marine protected area that forms part of the West Coast national park, South Africa; and the physiological strategies that allow this habitat to persist in sub- and supra-optimal temperatures. First, the …

Molecular and physiological investigation of trace metal stress in seagrass, Zostera muelleri
Despite the vast research on the negative effects of anthropogenic pollution on marine organisms, little is known about the toxicity responses of seagrasses to such perturbations. Understanding seagrass responses at the molecular level will ensure adequate conservation strategies to mitigate the …

Experimental studies of interactions between Zostera marina and the associated benthic fauna
… of eelgrass plants from plants within the Zostera bed; (3) Measure the seasonal variation of eelgrass turion length over an annual cycle and determine its correlation to biomass (dry weight); (4) Examine, by means of field experiments, the importance of incident solar irradiation in …

Acclimation of marine macrophytes (Saccharina latissima and Zostera marina) to water flow
… alga Saccharina latissima and the angiosperm Zostera marina, to water flow in nature and in controlled experiments. Limitation of photosynthesis of both species by the availability of dissolved inorganic carbon (DIC) was increased under low current velocities. Physiological acclimation to low …

Potential Impacts of Climate Change on Photochemistry of <i>Zostera Marina</i> L.
… and survival of the temperate eelgrass <em>Zostera marina L</em>., but the acclimation of photoprotective mechanisms in this context has not been characterized. This study aimed to quantify the long-term impacts of ocean acidification on photochemical control mechanisms that promote …

Estudios sobre el crecimiento en Zostera noltii Hornem: Dinámica estacional y aspectos ecofisiológicos
Zostera noltii es una fanerógama marina de pequeño porte que habita el intermareal de gran parte de la costa Atlántica Europea. En los fangos intermareales del sur de la Peninsula Iberica, bajo condiciones estacionales habituales, estas poblaciones describen un patrón anual unimodal controlado …

Molecular and cellular investigations of photosynthesis driven carbon fixation in the seagrass Zostera muelleri
Seagrasses are marine foundation species that have evolved to live in shallow coastal waters, an environment regularly subjected to changes through tidal patterns and anthropogenic activity. Global seagrass coverage is declining worldwide, mainly driven by decreasing water quality due to …

Blue carbon sequestration potential in Zostera marina eelgrass beds of the K'omoks Estuary, British Columbia
… for carbon sequestration was assessed in Zostera marina eelgrass bed sediments of the K’ómoks Estuary. Some of the assessed areas are found to be non-depositional. In areas of deposition the sediment accumulation rate is 0.23 to 0.78 g cm-2 yr-1, and the carbon concentration range in …

New Zealand seagrass (Zostera muelleri) response to acute sedimentation: Linking non-structural carbohydrate reserves to resilience
… affects New Zealand’s only seagrass species, Zostera muelleri. This thesis, therefore explores how Z. muelleri responds to catastrophic burial (acute) events in Tauranga Harbour, New Zealand. Non-structural carbohydrates (NSC) are synthesised and stored in seagrass tissues when photosynthetic …

Physico-chemical factors influencing the spatial and temporal distribution of the seagrass Zostera capensis in Langebaan lagoon
… the main physico-chemical factors influencing Zostera capensis biomass and distribution in Langebaan Lagoon. Five sites within the Langebaan Lagoon were selected and within these sites a minimum of three and maximum of ten Z. capensis beds were sampled, depending on the availability of the …

Studies of the horizontal and vertical distributional patterns of diatoms epiphytic on eel grass, Zostera marina L.
… periodicity of diatoms epiphytic on eelgrass, Zostera marina L., in the vicinity of Gloucester Point, Virginia. Samples were collected in August 1963 and June and July 1964. Horizontal and vertical distributional patterns were demonstrated with respect to the change of total numbers of …

Interactive effects of temperature and grazing by seagrass limpets (Siphonaria compressa and Fissurella mutabilis) on seagrass (Zostera capensis)
… and at a local level, cover of the seagrass Zostera capensis has declined by 38% over the last 50 years in Langebaan Lagoon, with associated losses of invertebrate abundance by 70% in certain areas. Two limpets, Siphonaria compressa and Fissurella mutabilis depend on Zostera capensis for …

Physiological and Molecular Responses of Eurythermal and Stenothermal Populations of <i>Zostera Marina</i> L (Eelgrass) to Climate Change
… populations of cosmopolitan species such as <em>Zostera marina</em> L. (eelgrass) remains largely unknown. This study analyzed whole-plant performance metabolic profiles and gene expression patterns of distinct eelgrass populations in response to CO<sub>2</sub> enrichment. Populations were …

Evaluating eelgrass (Zostera marina) as a juvenile habitat for rockfishes : contributions of site characteristics and larval supply to juvenile abundance
… conservation planning. In this study, the use of Zostera marina beds in Barkley Sound by juvenile rockfishes (Sebastes spp.) was investigated. Rockfish have been observed in Z. marina beds by many researchers, however, their abundance and distribution between beds has been shown to be variable. …

On the life history, systematics and ecology of Ruppia maritima L. (Potamogetonaceae) in lower Chesapeake Bay
… Bay, Ruppia maritima L. (Potamogetonaceae) and Zostera marina L. (Zosteraceae) form an important submerged aquatic vegetation community. Research in Chesapeake Bay has focused primarily on Zostera marina. Ruppia maritima occurs abundantly in large monospecific stands as well as in mixed stands …
