Trophic Ecology of Deep-Sea Megafauna in the Ultra-Oligotrophic Southeastern Mediterranean Sea

Frontiers in Marine Science, 2022
The trophic ecology of fourteen species of demersal fishes and six species of demersal decapod crustaceans from the continental slope and rise of the Southeastern Mediterranean Sea (SEMS) was examined using stable isotope analysis. Mean δ13C values among

Cadmium accumulation in coastal demersal fish [PDF]

Marine Ecology Progress Series, 2006
The hepatic Cd burden, measured on 291 individuals of 4 species of demersal fish (Gadus morhua, Reinhardtius hippoglossoides, Hippoglossoides platessoides, and Raja radiata), is 2 to 5 times higher in fish from the open Gulf of St. Lawrence than in fish from the St. Lawrence Estuary, 600 km landward. The higher Cd burden in the open Gulf is not related

Distribution of Demersal Fishes on Unconsolidated Bottom Habitat of the Northern Gulf of Mexico [PDF]

, 2021
Benthic habitat on the continental shelf in the northern Gulf of Mexico (NGoM) is dominated by large plains of unconsolidated terrigenous sediment. This unconsolidated bottom habitat (UBH) is presumed to be sparsely inhabited by demersal fishes, and ...

Convergence and plasticity in the adaptive radiation of cichlid fishes [PDF]

, 2013
Ever since Charles Darwin and Alfred Wallace (1858) propelled our understanding about the importance of natural selection in the transformation of species, researchers endeavoured to use this intellectual foundation to explain larger patterns of ...

Diet of two large sympatric teleosts, the ling (Genypterus blacodes) and hake (Merluccius australis). [PDF]

PLoS ONE, 2010
Ling and hake are tertiary consumers, and as a result both may have an important structuring role in marine communities. The diets of 2064 ling and 913 hake from Chatham Rise, New Zealand, were determined from examination of stomach contents.

The Role of Carrion Supply in the Abundance of Deep-Water Fish off California [PDF]

, 2012
Few time series of deep-sea systems exist from which the factors affecting abyssal fish populations can be evaluated. Previous analysis showed an increase in grenadier abundance, in the eastern North Pacific, which lagged epibenthic megafaunal abundance,

Associações entre macroinvertebrados e peixes demersais na armação do Itapocoroy, Penha, Sc, Brasil

Brazilian Archives of Biology and Technology, 1998
In the period of January and December, 1995, there were collected by means of overtrawl, 12977 samples of macroinvertebrates and demersal fishes, in the Armação do Itapocoroy, Penha (SC), between the depths of 6 to 10 meters, in the periods of morning ...

Coral-inhabiting Trapezia crabs forage on demersal plankton

Frontiers in Marine Science, 2022
The Trapeziidae constitute a widely distributed and common family of obligatory coral-dwelling crabs on Indo-west Pacific coral reefs, feeding on coral tissue and mucus.

The effect of fishing on demersal fish community dynamics: an hypothesis [PDF]

ICES Journal of Marine Science, 2001
Fishing acts like a predator; it alters the extent of competition and allows the coexistence of competitive species. To test this hypothesis, several component elements are addressed. The variability of biomass in demersal fish communities is analysed to seek evidence that biotic interactions play a role in community dynamics.

The effects of fishing on demersal fish communities of the Scotian Shelf [PDF]

ICES Journal of Marine Science, 2000
Since the 1970s, average individual weight of commercially targeted demersal fish on the Scotian Shelf (Canada) decreased by 51% on the eastern shelf and by 41% on the western shelf. For both systems, the integrated community size spectrum showed long-term declines in proportions of large fish and survey cpue of most targeted species.
