Carbon emissions threaten marine species
No one had great expectations about the outcome of discussions on climate change at the recent G8 summit of the world's wealthiest nations in Scotland, and the modest resulting statement did little to reassure researchers that the topic is being taken as seriously as many feel it demands. " At the heart of the communique is a disappointing failure by the leaders of the G8 unequivocally to recog...
متن کاملDigestive Enzymes in Marine Species
The proteolytic activities of the digestive tract of three carnivorous fish species (Sebastes mentella, Scophthalmus maximus, Sparus aurata) have been studied. The activity found in the stomach showed a pH optimum of 2.0 for all species, whereas this was in the alkaline range (9.5-10.0) in the intestinal extracts. Similar optimal temperature was measured for all species, although higher residua...
متن کاملPotential ramifications of the global economic crisis on human-mediated dispersal of marine non-indigenous species.
The global economy is currently experiencing one of its biggest contractions on record. A sharp decline in global imports and exports since 2008 has affected global merchant vessel traffic, the principal mode of bulk commodity transport around the world. During the first quarter of 2009, 10% and 25% of global container and refrigerated vessels, respectively, were reported to be unemployed. A la...
متن کاملGlobal Invasions of Marine and Estuarine Habitats by Non-Indigenous Species: Mechanisms, Extent, and Consequences1
Synopsis. Non-indigenous species (NIS) are increasingly conspicuous in marine and estuarine habitats throughout the world, as the number, variety, and effects of these species continue to accrue. Most of these NIS invasions result from anthropogenic dispersal. Although the relative importance of different dispersal mechanisms varies both spatially and temporally, the global movement of ballast ...
متن کاملNon-indigenous species as stressors in estuarine and marine communities: Assessing invasion impacts and interactions
Invasions by non-indigenous species (NIS) are recognized as impoltant stressors of many communities throughout the world. Here, we evaluated available data on the role of NIS in marine and estuarine communities and their interactions with other anthropogenic stressors, using an intensive analysis of the Chesapeake Bay region as a case study. First, we reviewed the reported ecological impacts of...
