Habitat selection and diet composition of greylag geese Anser anser and barnacle geese Branta leucopsis during fall and spring staging in relation to management in the tidal marshes of the Dollard. Changes in preferences of gestating heifers fed untreated or ammoniated straw in different flavours. Influence of free-choice vs. mixed-ration diets on food intake and performance of fattening calves.

The oil released during the Deepwater Horizon (DWH) oil spill may have both shortand long-time impacts on the northern Gulf of Mexico ecosystems. An understanding of how the composition and concentration of the oil are altered by weathering, including chemical, physical and biological processes, is needed to evaluate the oil toxicity and impact on the ecosystem in the northern Gulf of Mexico. T...

Dittrichia viscosa is a Mediterranean ruderal species that over the last decades has expanded into new habitats, including coastal salt marshes, ecosystems that are per se fragile and threatened by human activities. To assess the potential risk that this native-invasive species represents for the genuine salt marsh vegetation, we compared its distribution with that of Inula crithmoides, a taxon...

In recent decades the grass Phragmites australis has been aggressively invading coastal, tidal marshes of North America, and in many areas it is now considered a nuisance species. While P. australis has historically been restricted to the relatively benign upper border of brackish and salt marshes, it has been expanding seaward into more physiologically stressful regions. Here we test a leading...

The landscape of the Mesopotamian floodplain is mainly structured by channel processes, including formation levees, meanders, scrollbars, oxbow lakes, crevasse splays, distributary channels, inter-distributary bays, and marshes. Moreover, several human-made features also form shape this landscape, such as canals, roads, trenches, farms, settlement sites ranging in size from villages to cities. ...

We experimentally examined plant zonation in a previously unstudied Chilean salt marsh system to test the generality of mechanisms generating zonation of plants across intertidal stress gradients. Vertical zonation in this system is striking. The low-lying clonal succulent, Sarcocornia fruticosa, dominates the daily flooded low marsh, while intermediate elevations are dominated by the much tall...

Marshes in the urban Jamaica Bay Estuary, New York, USA are disappearing at an average rate of 13 ha/yr, and multiple stressors (e.g., wastewater inputs, dredging activities, groundwater removal, and global warming) may be contributing to marsh losses. Among these stressors, wastewater nutrients are suspected to be an important contributing cause of marsh deterioration. We used census data, rad...

The drying of saturated soil, and the occurrence of socalled malarious disease, have, from very early periods, been connected as cause and effect; and that invisible, imponderable, chemically unrecognizable agent we call malaria, has been supposed to be more freely evolved the greater the ground saturation. Thus drying marshes have been esteemed more unhealthy than either ground covered altoget...

Abstract. Nature-based solutions are increasingly suggested for mitigating coastal flood risks in the face of climate change. Managed realignment (MR), a adaptation strategy that entails landward defences to restore habitats (often salt marshes), plays pivotal role implementing nature-based zone. Across Europe, more than 130 sites have been implemented so far, often harness their potential miti...
