Effects of geostrophic kinetic energy flux on the three-dimensional distribution of fish larvae of mesopelagic species (Vinciguerria lucetia, Diogenichthys laternatus, Benthosema panamense and Triphoturus mexicanus) in the southern Gulf of California during summer and fall seasons of stronger stratification were analyzed. The greatest larval abundance was found at sampling stations in geostroph...

We combined conventional dietary sampling (2002) with stable isotope analysis of nitrogen (δ15N) and carbon (δ13C) in feathers of Leach’s storm-petrels Oceanodroma leucorhoa (2001 and 2002) to investigate temporal, sexand age-related variation in diet and trophic position, at Baccalieu Island, Newfoundland, Canada. Nestlings are fed mainly fish and crustaceans (ca. 90 and 9% by mass, respective...

An important aspect of population dynamics for coral reef fishes is the input of new individuals from the pelagic larval pool. However, the high biodiversity and the difficulty of identifying larvae of closely related species represent obstacles to more fully understanding these populations. In this study, we combined morphology and genetic barcoding (Cytochrome Oxidase I gene) to characterize ...

Mesopelagic fish populations are characterised by high species richness and abundance, have been identified as important contributors to the active carbon fluxes in open ocean. We report variability communities of mesopelagic between five zones around Iberian Peninsula, i.e. Balears Alboran Mediterranean, Cadiz, Lisboa Galicia Atlantic. Day night samples were collected from 7 layers water colum...

The feeding habits of 4 species of Plesionika inhabiting the Alboran Sea (SW Mediterranean) at depths between 29 and 790 m were analyzed. Included within the trophic guild of nonmigratory macroplankton feeders, Plesionika spp. preferably exploited mesopelagic resources (mainly euphausiids and Myctophidae). Deep-bathyal species (P. martia, P. gigliolii and P. edwardsi) fitted better within this ...

A region of distinct oceanographic features that result from the meeting of several water masses is marked by Cape Hatteras, North Carolina, between the Middle Atlantic Bight (MAB) and South Atlantic Bight (SAB). The features are dynamic, corresponding, in part, to the degree of water exchange between the MAB and SAB. The extent of larval "sh transport via these features could have implications...

The remote Franz Josef Land (FJL) Archipelago is the most northerly land in Eurasia and its fish fauna, particularly in nearshore habitats, has been poorly studied. An interdisciplinary expedition to FJL in summer 2013 used scuba, seines, and plankton nets to comprehensively study the nearshore fish fauna of the archipelago. We present some of the first underwater images for many of these speci...
