Cost-efficiency improvement of bivalves shells preparation when tracing their g...

Developing methodologies employed to trace the geographic origin of seafood as accurate and fast as possible can help to speed-up the delivery of results to legal authorities, reduce associated costs and minimize environmental impacts (associated with the residues generated). The present study evaluated if trace element fingerprints (TEF) of a small homogenized subsample of Manila clams (Ruditapes philippinarum...

Revealing the illegal harvesting of Manila clams (ruditapes philippinarum) usin...

The Manila clam (Ruditapes philippinarum) is one of the most traded bivalves in the world. Knowing its harvesting location is therefore paramount to guarantee the safety of consumers. The present study employs fatty acid (FA) profiles of the adductor muscle (AM) to reveal the most likely harvesting location of four batches of Manila clams suspected of having been illegally sourced from the Tagus estuary. In thi...

Response of vertebrate scavengers to power line and road rights-of-way and its ...

Linear infrastructures, such as power lines and roads, are an important source of bird mortality. However, little is known on the potential effect of these infrastructures on local scavenger guilds, their foraging activity and the resulting bird carcass removal patterns. This is an important source of bias in studies aiming to quantify bird fatalities due to linear infrastructures. We used camera-traps to recor...

Supply and larval traits at metamorphosis of a coastal marine invertebrate with...

Patterns of larval supply and larval condition at metamorphosis play key roles in the structure and dynamics of marine populations. Hence, biological and environmental conditions driving the dispersion of larval individuals, shape early life phenotypes, and influence their survival and post-settlement success. We performed a study over two consecutive years at Ria de Aveiro (Portugal), a coastal lagoon influenc...

Distinct Bleaching Resilience of Photosynthetic Plastid-Bearing Mollusks Under ...

The impact of temperature on photo-symbiotic relationships has been highly studied in the tropical reef-forming corals but overlooked in less charismatic groups such as solar-powered sacoglossan sea slugs. These organisms display one of the most puzzling symbiotic features observed in the animal kingdom, i.e., their mollusk-plastid association, which enables them to retain photosynthetic active chloroplasts (i....

Small pelagics in a changing ocean : Biological responses of sardine early stag...

Small pelagic fishes are known to respond rapidly to changes in ocean climate. In this study, we evaluate the effects of future environmental warming (+2°C) during the early ontogeny of the European sardine, Sardina pilchardus. Warming reduced the survival of 30-day-old larvae by half. Length at hatching increased with temperature as expected, but no significant effect was observed on the length and growth at 3...

Foraging behaviour, swimming performance and malformations of early stages of c...

Early life stages of many marine organisms are being challenged by climate change, but little is known about their capacity to tolerate future ocean conditions. Here we investigated a comprehensive set of biological responses of larvae of two commercially important teleost fishes, Sparus aurata (gilthead seabream) and Argyrosomus regius (meagre), after exposure to future predictions of ocean warming (+4 °C) and...
