Under the cover of darkness: Foraging behaviour increases on cloudy, new moon nights in a pelagic seabird

open access: yesIbis, EarlyView.
While many visual predators feed exclusively during the day, others exploit foraging opportunities at night, although the efficiency with which they do so is strongly influenced by ambient light levels. We investigated the influence of variation in nocturnal light on the foraging behaviour of a small pelagic seabird, the European Storm‐petrel ...

Larval Arctic cod (Boreogadus saida) exhibit stronger developmental and physiological responses to temperature than to elevated pCO2

open access: yesJournal of Fish Biology, EarlyView.
Abstract High‐latitude ecosystems are simultaneously warming and acidifying under ongoing climate change. Arctic cod (Boreogadus saida) are a key species in the Arctic Ocean and have demonstrated sensitivity to ocean warming and acidification as adults and embryos, but their larval sensitivity to the combined stressors is unknown. In a laboratory multi‐

Distribution and ecology of the four Macrourus species by‐caught in the longline fishery at South Georgia, Southern Ocean

open access: yesJournal of Fish Biology, EarlyView.
Abstract Although Macrourus species are the main by‐catch across Southern Ocean longline fisheries, including around South Georgia, the lack of species‐specific data has hindered effective management and ecological understanding. Aggregation of macrourids at genus level masks critical interspecific differences in life‐history strategies and ...

Struktur vertikal upwelling – downwelling di Samudera Hindia Selatan Jawa hingga Selatan Bali berdasarkan salinitas musiman periode 2004 – 2010

open access: yesDepik Jurnal, 2013
Salinitas berperan penting untuk mengidentifikasi fenomena upwelling dan downwelling. Upwelling yang terjadi di samudera Hindia Selatan Jawa hingga Selatan Bali dipengaruhi oleh angin musim, ENSO (El Nino Southern Oscillation) dan IOD (Indian Oscillation

Remote-Sensing Estimation of Upwelling-Frequent Areas in the Adjacent Waters of Zhoushan (China)

open access: yesJournal of Marine Science and Engineering
Upwelling, which mixes deep and surface waters, significantly enhances the productivity of surface waters and plays a critical role in marine ecosystems, especially in key fishing areas like Zhoushan.

Influence of coastal upwelling on the air–sea gas exchange of CO2 in a Baltic Sea Basin

open access: yesTellus: Series B, Chemical and Physical Meteorology, 2013
During coastal upwelling cold water from the ocean interior with high CO2 concentration is brought up to the surface, allowing this water to interact with the atmosphere. This sets the stage for events with potentially altered sea–air CO2 fluxes.

Coastal upwelling seen in ocean temperature data

open access: yes, 2014
The phenomenon of wind-driven upwelling occurs when high coastal winds blow over the ocean surface, pushing warm surface waters offshore and allowing cooler, more nutrient rich water from below to rise up to the surface.

Age and growth of the spiny butterfly ray Gymnura altavela (Elasmobranchii, Gymnuridae) in the Southwest Atlantic (in situ) and under human care in a public aquarium (ex situ): Plasticity and population patterns

open access: yesJournal of Fish Biology, EarlyView.
Abstract This study provides the first age and growth assessment of the endangered spiny butterfly ray, Gymnura altavela (Linnaeus, 1758), in the Southwest Atlantic, while also updating the growth parameters (asymptotic disc width—DW∞ and growth coefficient—k) estimated in an ex situ a marine aquarium setting.

Upwelling intensity structures free-living and particle-associated bacterial communities in an eastern boundary upwelling system

open access: yesFrontiers in Marine Science
Eastern Boundary Upwelling Systems (EBUS) are among the most productive oceanic regions, driven by the upwelling of cold, nutrient-rich, and low-oxygen waters. These systems are increasingly affected by climate change, with intensified upwelling activity

Nodular Lesions in the Pyloric Caeca of Sardinella aurita (Teleostei) Associated With the Cestode Anthobothrium sp. 1 Larvae (Platyhelminthes: Eucestoda) Off Tunisia, Mediterranean Sea

open access: yesJournal of Fish Diseases, EarlyView.
ABSTRACT Examination of round sardinella Sardinella aurita Valenciennes, 1847 (Clupeidae) from the Gulf of Tunis (Tunisia) revealed the first local and Mediterranean record of Anthobothrium sp. 1 sensu Jensen & Bullard, 2010 (Tetraphyllidea incertae sedis, Anthobothrium).
