Benthic metabolism across a gradient of anthropogenic impact in three shallow coastal lagoons in NW Florida
Seagrasses are being lost at alarming rates worldwide, most often due to anthropogenic effects, but few reports have examined how seagrass loss affects the metabolism of coastal ecosystems. Here, we address this question by comparing both areal and system-integrated daytime benthic metabolic rates across 3 lagoons in the North Central Gulf of Mexico that display varying levels of abundance of t...
متن کاملCharacterization of Polyphenolic Content in the Aquatic Plants Ruppia cirrhosa and Ruppia maritima -A Source of Nutritional Natural Products.
Herein, the polyphenolic content in extracts of Ruppia cirrhosa (Petagna) Grande and Ruppia maritima L.was fully characterized for the first time. High amounts of the main compound chicoric acid (CA) (≤30.2 ± 4.3 mg/g) were found in both Ruppia species. In addition, eight flavonoids, namely the 3-O-glucopyranosides and 3-O-galactopyranosides, as well as malonylated 3-O-glycosides of quercetin a...
متن کاملMetagenomes of Mediterranean Coastal Lagoons
Coastal lagoons, both hypersaline and freshwater, are common, but still understudied ecosystems. We describe, for the first time, using high throughput sequencing, the extant microbiota of two large and representative Mediterranean coastal lagoons, the hypersaline Mar Menor, and the freshwater Albufera de Valencia, both located on the south eastern coast of Spain. We show there are considerable...
متن کاملThe effect of Ruppia cirrhosa features on macroalgae and suspended matter in a Mediterranean shallow system
The importance of shallow waters as a reservoir of biodiversity has been evidenced everywhere in the world both at temperate and tropical latitudes (Gray 1997; Duarte 2000; Raffaelli 2000; Pusceddu et al. 2003). Shallow waters function as a buffer system of interchange between open sea and land, and aquatic macrophytes represent key species regulating fluxes of energy and matter (Wetzel 1975). ...
متن کاملStable nitrogen isotopes in coastal macroalgae: geographic and anthropogenic variability.
Growing human population adds to the natural nitrogen loads to coastal waters. Both anthropogenic and natural nitrogen is readily incorporated in new biomass, and these different nitrogen sources may be traced by the measurement of the ratio of stable nitrogen isotopes (δ(15)N). In this study δ(15)N was determined in two species of macroalgae (Ascophyllum nodosum and Fucus vesiculosus), and in ...
