Cameras and carcasses: historical and current methods for using artificial food falls to study deep-water animals [PDF]

, 2007
Deep-ocean animals remain poorly understood compared to their shallow-water relatives, mainly because of the great cost and difficulty involved in obtaining reliable ecological data.

Morphosedimentary, Structural and Benthic Characterization of Carbonate Mound Fields on the Upper Continental Slope of the Northern Alboran Sea (Western Mediterranean)

Geosciences, 2022
Carbonate mounds clustering in three fields were characterized on the upper continental slope of the northern Alboran Sea by means of a detailed analysis of the morphosedimentary and structural features using high-resolution bathymetry and parametric ...

Distribution of skates and sharks in the North Sea: 112 years of change [PDF]

, 2016
How have North Sea skate and shark assemblages changed since the early 20th century when bottom trawling became widespread, whilst their environment became increasingly impacted by fishing, climate change, habitat degradation and other anthropogenic ...

Faunal zones of demersal fish across the continental shelf to slope in Tosa Bay, south-western Japan.

NIPPON SUISAN GAKKAISHI, 1985
Data on 47 otter trawls towed at depths of 30 to 400m in Tosa Bay show demersal fish fauna changes by depth. Results of cluster analysis of the data suggest that three distinct faunal zones exist on the continental shelf (30 to 100m), upper continental slope (165 to 400m), and between them (100 to 165m).

Escape Survival and Scale Damage Assessment of Red Mullet (Mullus barbatus Linnaeus, 1758) during Bottom Trawling in the Central Mediterranean Sea

Biology, 2023
Stock assessments routinely evaluate the status of commercially harvested species, but seldom account for the possible mortality of released or escaping fish.

Long-term change in benthopelagic fish abundance in the abyssal northeast Pacific Ocean [PDF]

, 2006
Food web structure, particularly the relative importance of bottom-up and top-down control of animal abundances, is poorly known for the Earth's largest habitats: the abyssal plains.

Contrasting management regimes indicative of mesopredator release in temperate coastal fish assemblages

Ecology and Evolution, 2023
The absence of functional top predators has been proposed as a mechanism acting to shape fish assemblages in temperate marine ecosystems, with cascading effects on lower trophic levels.

Supplements to the generalized quantitative assessments of benthic macrofauna in the Far-Eastern Seas and adjacent waters of the Pacific Ocean. Report 2. Regional and bathymetric features of biomass and density of its distribution for fish and some groups of invertebrates

Известия ТИНРО, 2016
Data on mean annual biomass (t) of the bottom macrofauna groups and main species in the Far-Eastern Seas and adjacent waters of the Pacific Ocean, by bathymetric ranges, and on density of their distribution (t/km2) are summarized.

STABILITY OF THE SPATIAL STRUCTURES OF DEMERSAL ASSEMBLAGE IN THE MOROCCAN SOUTHERN ATLANTIC ZONE

Applied Ecology and Environmental Research, 2007
Abstract. In this paper we study the stability of the spatial structure of demersal assemblages of the Moroccan southern Atlantic zone, ranging between Cap Boujdor (26°N) and Cap Blanc (20°50 'N). The data used are the frequencies of demersal species captured during trawling surveys along the continental shelf to less than 120 meters of depth; the ...

Temporal changes in the dietary niche of sympatric seals provides insight into the role of competition in population declines

Oikos, EarlyView.
Competition theory suggests that interspecific prey competition can result in changes to the dietary niche, but obtaining timeseries of data from sympatric species experiencing temporal variation in competition is challenging. Scotland is an important area for two species of seals, but over the past 20 years, populations of harbour seals Phoca vitulina
