Horizontal and vertical distribution of mesozooplankton species richness and composition down to 2,300 m in the southwest Atlantic Ocean

open access: yesZoologia (Curitiba), 2014
We describe the species richness, distribution and composition of mesozooplankton over the continental shelf and slope, and in the water masses in the Campos Basin, southwest Atlantic Ocean. We analyzed the mesozooplankton from two oceanographic cruises (

Vitamin A and carotenoids in certain invertebrates. III. Euphausiacea [PDF]

open access: yesJournal of the Marine Biological Association of the United Kingdom, 1955
Our published work has shown that the northern euphausiids, Meganyctiphanes norvegica, Thysanoessa raschii and T. inermis, contain much higher concentrations of vitamin A than we have found in any other marine Crustacea (Kon & Thompson, 1949a; Batham, Fisher, Henry, Kon & Thompson, 1951; Fisher, Kon & Thompson, 1952, 1953, 1954).

Lengths of Stay and Stopover Strategies of Western Sandpipers During Migration at Two Sites in British Columbia, Canada

open access: yesEcology and Evolution, Volume 15, Issue 1, January 2025.
Stopover duration (length of stay, LOS) is a key variable in avian migration ecology that reflects behavioral decisions to obtain fuel or continue travel between breeding and non‐breeding areas. We find the LOS of Western Sandpipers differs between two important stopover sites on the Pacific Coast of Canada, reflecting different migration strategies ...

Deepwater Sharks at Their Northern Limits—Distribution, Diet and Trophic Relations

open access: yesMarine Ecology, Volume 46, Issue 1, January 2025.
ABSTRACT Deepwater areas and continental slope regions south and west off Iceland are characterized by a relatively high species diversity and abundance of sharks that likely play a critical ecological role within this ecosystem. The study investigates trophic ecology of the sharks employing stomach content analysis and stable isotope analysis of ...

Which Novel Ingredient Should be Considered the “Holy Grail” for Sustainable Production of Finfish Aquafeeds?

open access: yesReviews in Aquaculture, Volume 17, Issue 1, January 2025.
ABSTRACT The immense production of fishmeal and fish oil is dramatically intensifying the severe state of pelagic fisheries overexploitation. The latter in conjunction with the increasing demand for low‐cost protein‐rich food supply prompt aquaculture to employ new practice. Several novel dietary ingredients are currently under evaluation for potential
