Microbial communities and biogeochemistry in an area of Engraulis encrasicolus spawning in the Sicilian Channel

Frontiers in Marine Science, 2014
Attempts to merge marine food webs and marine biogeochemical research have recently been developed in response to the need to understand how global change will impact marine ecosystems and resources (Salihoglu et al., 2013; Painting, et al., 2013). Among the multiple drivers that influence ecosystem dynamics, Link et al.

Sources and impacts of inorganic and organic fine sediment in salmonid spawning gravels in chalk rivers

, 2012
Poor salmonid spawning habitat due to excessive fine sediment inputs has been identified as a major factor limiting survival in chalk rivers. A lack of knowledge about the complex processes and factors affecting survival was the driver for this study and
