Mangroves are among the most well described and widely studied wetland communities in the world. The greatest threats to mangrove persistence are deforestation and other anthropogenic disturbances that can compromise habitat stability and resilience to sea-level rise. To persist, mangrove ecosystems must adjust to rising sea level by building vertically or become submerged. Mangroves may direct...
The terrestrial environment in the vicinity of La Hague nuclear reprocessing plant (COGEMA) is potentially influenced by two sources (atmospheric and marine) and by three ways of radionuclides transfer: 1) atmospheric fallout from old nuclear bombs experiments, 2) atmospheric fallout from gaseous throwing out from the reprocessing plant 3) marine aerosol and degassing (sea to land transfer) bea...
The present report deals with the measurement of fall-out radioactivity in Denmark in 1974. Strontium-90 was determined in samples from all over the country of precipitation, soil, ground water, sea water, grass, dried milk, fresh milk, grain, bread, potatoes, vegetables, fruit, total diet, drinking water, and human bone. Furthermore, 90Sr was determined in local samples of air, rain water, gra...
Comparisons were made of metal concentrations in water and sediment with those in the muscle and livers of three species of fish caught in four seawater reservoirs (two in the Odiel estuary and two in the Bay of Cádiz). The concentrations of a large number of metals in the water, sediment and fish were higher in the Odiel reservoirs than in those in Cádiz. We found high metal-enrichment factors...
Mission To safely collect and treat wastewater in compliance with all regulatory requirements using state‐of‐the‐ art technology in the most cost‐effective manner in order to improve the environment and enhance the quality of life in Fairfax County. Focus The Wastewater Management Program includes wastewater collection and conveyance, wastewater treatment, and planning and monitoring program a...
Patterns of seed dispersal in the wild sea beet (Beta vulgaris ssp. maritima) are predicted to be influenced by marine currents because populations are widely distributed along the European Atlantic coast. We investigated the potential influence of marine currents on the pattern of spatial genetic structuring in natural populations of sea beet. Populations were located along the French coasts o...
Systematically investigating the impacts of Pleistocene sea-level fluctuations on mangrove plants may provide a better understanding of their demographic history and useful information for their conservation. Therefore, we conducted population genomic analyses of 88 nuclear genes to explore the population dynamics of a mangrove tree Lumnitzera racemosa across the Indo-West Pacific region. Our r...
The coupling of renewable energy and hydrogen technologies represents in the mid-term a very interesting way to match the tasks of increasing the reliable exploitation of wind and sea wave energy and introducing clean technologies in the transportation sector. This paper presents two different feasibility studies: the first proposes two plants based on wind and sea wave resource for the product...
Marine-derived nutrients can increase primary productivity and change species composition of terrestrial plant communities in coastal and riverine ecosystems. We hypothesized that sea nutrient subsidies have a positive effect on nitrogen assimilation and seedling survival of non-nitrogen fixing species, increasing the relative abundance of non-nitrogen fixing species close to seashore. Moreover...
Cherry laurel (Laurocerasus officinalis Roemer Syn: Prunus laurocerasus L.) is a perennial wild fruit plant that is widely distributed in and around South-Eastern Black Sea, Marmara Sea, the Caspian Sea in the North and the East. However, breeding success of cherry laurel depends on early harvest, transient differences in taste, fruit color and flavor due to large number of biotic and abiotic s...
