Habitat Selection Response of Small Pelagic Fish in Different Environments. Two Examples from the Oligotrophic Mediterranean Sea
A number of scientific papers in the last few years singled out the influence of environmental conditions on the spatial distribution of fish species, highlighting the need for the fisheries scientific community to investigate, besides biomass estimates, also the habitat selection of commercially important fish species. The Mediterranean Sea, although generally oligotrophic, is characterized by...
متن کاملDoes habitat or depth influence catch rates of pelagic species?
The efficiency of a pelagic longline fishing operation and the species composition of the resulting catch is influenced primarily by the relationship between the distribution of hooks and species vulnerability, with vulnerability described by either depth or some suite of environmental variables. We therefore fitted longline catch rate models to determine whether catch is estimated better by ve...
متن کاملChasing after Non-cyanobacterial Nitrogen Fixation in Marine Pelagic Environments
Traditionally, cyanobacterial activity in oceanic photic layers was considered responsible for the marine pelagic dinitrogen (N2) fixation. Other potentially N2-fixing bacteria and archaea have also been detected in the pelagic water column, however, the activity and importance of these non-cyanobacterial diazotrophs (NCDs) remain poorly constrained. In this perspective we summarize the N2 fixa...
متن کاملInformation Technology and Firm Profitability in Network Environments
Despite prolific research on IT business value, this stream of research still encounters considerable limitations such as inconsistent findings of the direct link between IT and firm profitability and the demonstration of the indirect relationship between IT and specific aspects of firm value without explicitly considering network environments. To overcome the limitations caused by utilizing th...
متن کاملOrientation in “Featureless” Environments: the Extreme Case of Pelagic Birds
During the breeding period, pelagic birds such as petrels and penguins commute between their colony and distant foraging grounds. Like migrating birds, they are able to travel large distances to reach suitable environmental conditions and/or food supplies. To accomplish their astonishing foraging trips, they should dispose of similar navigation capacities. Pelagic birds present a particular int...
