Annual variations of biomass and photosynthesis in Zostera marina at its southern end of distribution in the North Pacific

Eelgrass Zostera marina in subarctic Greenland: dense meadows with slow biomass turnover in cold waters

“…We used air temperature as a substitute for sea-water temperature because local monthly water temperatures were not always provided in the cited literature. Previous studies show a close correlation between air and water temperature (Cabello-Pasini et al 2003, Lee et al 2006, although deviations occur due to factors such as local sea currents, upwelling of cool water to the sea surface and river runoff. The geo graphical coordinates were ob tained either directly from the cited literature or deduced from the descriptions of the sampling sites.…”

“…The dense and typically mono specific stands contribute to carbon storage, nutrient retention, sediment stabilization, improvement of water clarity and enhanced biodiversity (van der Heide et al 2007, McGlathery et al 2012. Eelgrass is distributed over a wide latitudinal range (~5000 km) from warm subtropical regions of the eastern Pacific (26°N, Gulf of California) in the south to arctic regions in the north (Ostenfeld 1927, den Hartog 1970, Cabello-Pasini et al 2003, Green & Short 2003. It has been observed as far north as the ABSTRACT: Eelgrass Zostera marina L. is the most dominant seagrass species throughout the temperate northern hemisphere, and knowledge on its distribution and production in relation to climatic conditions is relevant for predicting the future of the meadows.…”

Benthic metabolism in San Quintin Bay, Baja California, Mexico

“…The most conspicuous benthic community in the system is the eelgrass (Zostera marina) (IbarraObando & Huerta-Tamayo 1987, Poumian-Tapia & Ibarra-Obando 1999. Ward et al (2003) assessed changes in major habitat coverage between 1987 and 2000. As simplified and generalized from Ward et al (2003), marine habitats are represented by exposed and submerged eelgrass, mudflat, channel (deep mud) and salt marsh (Fig.…”

Annual and perennial life history strategies of Zostera marina populations under different light regimes

“…Z. marina is the most widely distributed marine angiosperm in the northern hemisphere and commonly exhibits a perennial life cycle (Cabello-Pasini et al 2003, Park et al 2009). Perennial Z. marina populations depend on both asexual and sexual reproduction to maintain existing meadows and colonize new regions, but the contribution of each reproductive strategy varies greatly, ABSTRACT: The seagrass Zostera marina is genetically considered to be perennial, but annual populations of this species exist as well and are under severe environmental stress in many geographical locations.…”
