Long-term co-occurrence and gregariousness in the migratory common stingray using network analysis Open
Aggregations and social interactions play an important role in the movement ecology of many animals, including elasmobranchs. Several of these species have shown the capability of carrying out complex social behaviours, and the importance …

Long-distance migrations and seasonal movements of meagre (Argyrosomus regius), a large coastal predator, along the Iberian Peninsula coast Open
Background The meagre, Argyrosomus regius , is a large coastal predatory fish inhabiting waters from the north-eastern Atlantic and Mediterranean Sea, where it is targeted by commercial and recreational fisheries. Previous genetic studies …

Meagre (Argyrosomus regius) move westward with favourable flows along the south coast of Portugal Open
Based on acoustic detections from a network of five stations along the south coast of Portugal, 25 transits of tagged meagre were identified between 2019 and 2020, mostly in summer. Comparisons with hourly current measurements from a moore…

Depth and temperature preferences of meagre, Argyrosomus regius, as revealed by satellite telemetry Open
Argyrosomus regius (commonly referred to as meagre), is one of Europe’s largest coastal bony fish species and supports important recreational and commercial fisheries in the Atlantic and Mediterranean coasts. Demand for this species, and m…

Small coastal marine protected areas offer recurring, seasonal protection to the common stingray (Dasyatis pastinaca) Open
Marine protected areas (MPAs) are a crucial tool in safeguarding marine biodiversity. However, elasmobranchs are often not the primary protection target of MPAs, and their contribution to protect these species remains to be better understo…

Ocean warming favours a northern <i>Argyrosomus </i>species over its southern congener, whereas preliminary metabolic evidence suggests that hybridization may promote their adaptation Open
Anthropogenic-induced climate change is having profound impacts on aquatic ecosystems, and the resilience of fish populations will be determined by their response to these impacts. The northern Namibian coast is an ocean warming hotspot, w…

Transdisciplinarity in transformative ocean governance research—reflections of early career researchers Open
This paper interrogates the concept of transdisciplinarity, both theoretically and practically, from a perspective of early career researchers (ECRs) in transformative ocean governance research. Aiming to advance research methodologies for…

Marine Heatwaves Exceed Cardiac Thermal Limits of Adult Sparid Fish (Diplodus capensis, Smith 1884) Open
Climate change not only drives increases in global mean ocean temperatures, but also in the intensity and duration of marine heatwaves (MHWs), with potentially deleterious effects on local fishes. A first step to assess the vulnerability o…

The emergence of marine recreational drone fishing: Regional trends and emerging concerns Open
Online evidence suggests that there has been an increase in interest of using unmanned aerial vehicles or drones during land-based marine recreational fishing. In the absence of reliable monitoring programs, this study used unconventional …

Linefish resilience in the Anthropocene: The proceedings of the 5th Southern African Marine Linefish Symposium Open
The Southern African Marine Linefish Symposium is an event where scientists come together and present any contemporary research relating to linefisheries in the region. The symposium occurs every 4 - 7 years depending on circumstances and …

Implantation, orientation and validation of a commercially produced heart-rate logger for use in a perciform teleost fish Open
Quantifying how the heart rate of ectothermic organisms responds to environmental conditions (e.g. water temperature) is important information to quantify their sensitivity to environmental change. Heart rate studies have typically been co…

Integrated genetic and morphological data support eco‐evolutionary divergence of Angolan and South African populations of <span><i>Diplodus hottentotus</i></span> Open
The genus Diplodus presents multiple cases of taxonomic conjecture. Among these the D. cervinus complex was previously described as comprising three subspecies that are now regarded as separate species: Diplodus cervinus , Diplodus hottent…
