Seafood consumption has been traditionally very important in Spain (about 36.5 kg per capita
consumed in 2003). Hake (merluza) is the main fish species consumed in quantity and value
terms in Spain. But commercialised as hake can be found several fish species and presentations.

The collective chemosensing of nonexcitable mammalian cells involves a biochemical network that features gap junction communications and heterogeneous single cell activities. To understand the integrated multicellular chemosensing, we study the calcium dynamics of micropatterned fibroblast cell colonies in response to adenosine triphosphate (ATP) stimulation. We find that the cross-correlation function...
Antarctic krill are a key component of the diet of Adélie penguins inhabiting the Western
Antarctic Peninsula (WAP), yet our understanding of the variability of krill distribution
patterns within nearshore penguin feeding grounds is limited. A recent study of the foraging
patterns of penguins breeding in the northern WAP suggests...
Nassau grouper Epinephelus striatus are a large bodied, top level predator that is ecologically important throughout
the Caribbean. Although typically solitary, Nassau grouper form large annual spawning aggregations at predictable times in specific
locations. In 2003, The Cayman Islands Marine Conservation Board established protection for a newly rediscovered Nassau
grouper...
Satellite imagery of chlorophyll a concentration (chl a) provides the only holistic perspective
of productivity in marine ecosystems worldwide, yet its utility for understanding and
predicting the distribution of upper trophic-level predators remains equivocal. We tested the
hypothesis that remotely sensed chl a measurements spanning a decade can predict marine...
North Atlantic right whales were instrumented with suction-cup mounted, time-depth recorders (TDR) during the summers of 2000 and 2001 to examine their diving and foraging behavior. Simultaneous observations of temperature, salinity and the vertical distribution of their principal prey, Calanus finmarchicus stage 5 copepodites (C5), were obtained alon

Mesoscale fronts occur frequently in many coastal areas and often are sites of elevated
productivity; however, knowledge of the fine-scale distribution of zooplankton at these
fronts is lacking, particularly within the mid-trophic levels. Furthermore, small (<13 cm) gelatinous
zooplankton are ubiquitous, but are under-studied, and their abundances underestimated
due to...

Fishing overcapacity has lead to unsustainable harvesting and rent dissipation in global fisheries. Only government intervention of some kind can lead to a reduction in capacity. If efficiency is the primary objective for the regulator, then the least efficient vessels should be decommissioned. Here we analyze the Swedish fishery using...
Increasingly, natural resource management agencies and nongovernmental organizations are sharing monitoring data across geographic and jurisdictional boundaries. Doing so improves their abilities to assess local-, regional-, and landscape-level environmental conditions, particularly status and trends, and to improve their ability to make short-and long-term management decisions. Status monitoring assesses the current...
