Behavioral Evidence of Predator–Predator Commensalism: Cobia Track and Feed on Prey Disturbed by Southern Stingrays

open access: yesEthology, EarlyView.
We documented a novel predator–predator commensal foraging interaction between cobia (Rachycentron canadum) and a southern stingray (Hypanus americanus) in a shallow coastal habitat of Biscayne Bay, Florida. Using drone‐based observations, we recorded a 7‐min sequence in which a cobia closely tracked the stingray's movements and fed on prey disturbed ...

Thermal evolution of Cathaysian block along the South China margin since the Late Cretaceous: evidence from low-temperature thermochronology

open access: yesFrontiers in Earth Science
The Cathaysian Block has undergone complex tectonic transformation since the Mesozoic, with significant topographic and geomorphological changes due to large-scale magmatism, as well as tectonism in the central area.

Chasing Fish: 130 Years of Innovation, Displacement and Depletion in Scottish Fisheries

open access: yesFish and Fisheries, EarlyView.
ABSTRACT Rebuilding the depleted fisheries of the 21st century requires an understanding of past drivers of their decline. Despite Scotland's central role in the commercial exploitation of North Sea fisheries for over a century, associations between technological innovations, regulatory introductions and fishery landings have not previously been ...

Distribution of surface sediments off Indus delta on the continental shelf of Pakistan [PDF]

open access: yes, 1993
Surface sediments from the continental shelf area off Indus delta were analysed for their textural characteristics and carbonate content. The sediments are largely silt, silty clay and clayey silty sand.

Body Condition as a Shared Response to Environment in a Commercially Important Demersal Fish Assemblage

open access: yesFish and Fisheries, EarlyView.
ABSTRACT Measures of an organism's weight at a given length are often considered reliable indicators of energy reserves or ‘condition’, which can be related to fecundity and risk of mortality. Understanding the impact of environmental change on fish condition may therefore inform sustainable management of human activities in marine ecosystems.

Evolution of the Giant Foresets Formation, northern Taranaki Basin, New Zealand [PDF]

open access: yes, 2002
Plio-Pleistocene aggradation and progradation has resulted in the rapid outbuilding of the continental shelf margin, northern Taranaki Basin. Seismic reflection profiles reveal that this outbuilding is characterised by bold clinoforms which offlap in a ...

Classification of European Illex coindetii and Loligo forbesii Squid Stocks by Trace Element Analysis of Statoliths

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT We investigated whether statolith microchemistry analysis could classify ommastrephid and loliginid squid species into fishery stocks. Statolith nucleus (early life stage) and edge (life stage at time before catch) of Illex coindetii (Verany, 1839) and Loligo forbesii (Steenstrup, 1856) from various areas of the North East Atlantic Ocean and ...

Sources and mechanisms for the enrichment of highly reactive iron in euxinic Black Sea sediments [PDF]

open access: yes, 2004
The deep basinal euxinic sediments of the Black Sea are enriched in iron that is highly susceptible to sulfidization compared to oxic/suboxic continental margin sediments in the Black Sea and oxic/dysoxic continental margin and deep-sea sediments ...
