Article
Full-text available
Small pelagic fishes have the ability to disperse over long distances and may present complex evolutionary histories. Here, Old World Anchovies (OWA) were used as a model system to understand genetic patterns and connectivity of fish between the Atlantic and Pacific basins. We surveyed 16 locations worldwide using mtDNA and 8 microsatellite loci fo...
Article
Full-text available
Natural populations of widely distributed organisms often exhibit genetic clinal variation over their geographical ranges. The European anchovy, Engraulis encrasicolus, illustrates this by displaying a two-clade mitochondrial structure clinally arranged along the eastern Atlantic. One clade has low frequencies at higher latitudes, whereas the other...

Genetic variation (mtDNA) of the European conger eel, Conger conger, was compared across five locations in the north-eastern Atlantic (Madeira, Azores, South Portugal, North Portugal and Ireland) and one location in the western Mediterranean (Mallorca). Genetic diversity of conger eel was high, and differentiation among regions was not significant....
Presentation
Small pelagic fishes (SPF) play a central role in marine ecosystems and are particularly sensitive to environmental changes. They are ectothermic, have high-metabolic requirements and high dependence on aerobic metabolism. In the context of climate change, shifts in these populations may have dramatic consequences in the ecosystem, and consequently...
Article
Full-text available
Spawning habitats of cold-water, European small pelagic fishes have shifted poleward in the last three decades coincident with gradual ocean warming. We predicted present-day, season-specific habitat suitability for spawning by European sardine Sardina pichardus in the Atlantic Ocean and Mediterranean and Black Seas, and projected climate-driven ch...
Article
Full-text available
Climate change often leads to shifts in the distribution of small pelagic fish, likely by changing the match-mismatch dynamics between these sensitive species within their environmental optima. Using present-day habitat suitability, we projected how different scenarios of climate change (IPCC Representative Concentration Pathways 2.6, 4.5 and 8.5)...
Article
Full-text available
Ongoing climatic changes, with predictable impacts on marine environmental conditions, are expected to trigger organismal responses. Recent evidence shows that, in some marine species, variation in mitochondrial genes involved in the aerobic conversion of oxygen into ATP at the cellular level correlate with gradients of sea surface temperature and...

Science-based management of marine fisheries and effective ecosystem monitoring both require the analysis of large amounts of often complex and difficult to collect information. Legislation also increasingly requires the attainment of good environmental status, which again demands collection of data to enable efficient monitoring and management of...

While studying marine organisms with complex life cycles, identifying the patterns, processes, timings and habitats associated with early-life stages becomes critical to our understanding on how populations vary over time. Here, we aimed to characterize the breeding population of a temperate cryptobenthic fish, the ringneck blenny Parablennius pili...

Under the hypothesis ”bigger-is-better”, it is expected that larger fish produce larger offspring. Larger initial body sized larvae were found to be able to maintain advantage to important life-history events and therefore have higher chances of survival. Here, we characterized the reproductive male population of the ringneck blenny Parablennius pi...

Full-text available
The European anchovy has been the focus of numerous population genetic studies, most of which exposing high levels of haplotype diversity. However, Keskin and Atar (2012) revealed rather singular results of null haplotype diversities. We therefore call for caution when considering these findings.

Ecological niche modelling (ENM) determines habitat suitability of species by relating records of occurrence to environmental variables. Here, we investigated habitat suitability of four terrestrial slugs of the genus Geomalacus from the Iberian Peninsula using ENM. The potential distribution of these species was estimated using maximum entropy mod...

In the marine pelagic realm, the lack of prominent barriers to dispersal is thought to facilitate the connectivity of populations and prevent their genetic differentiation. Moreover, small pelagic fishes are generally characterized by large population sizes and consequently low levels of genetic drift. The “central-marginal” theory postulates that...

Question
Hi to all,
I'm looking for examples of marine organisms whose genetic patterns show that individuals/ populations from the Bay of Biscay are genetically closer to the northwestern Mediterranean specimens rather than to Atlantic adjacent areas. Does anyone know?
Thank you very much.

Project
The BiodivAMP project – Development of tools for monitoring and protection of biodiversity in Marine Protected Areas along the Portuguese coast (ref. FA_96_2017_045) is supported by Fundo Azul programme, in the scope of the public announcement for Monitoring and Protection of the marine environment, by the Directorate General for Maritime Policy of the Portuguese Ministry of the Sea. BiodivAMP is built along 3 main axis: - Elaboration of a Good Practice Guide for monitoring, management and governance of MPAs in the Portuguese coast; - Implementation of a pilot project using environmental DNA as a non-invasive tool for biodiversity monitoring; - Promote Portuguese MPAs and disseminate the project results and activities, aiming to show the public the importance of these protected areas, as well as making tools available for stakeholders to manage AMPS in an effective and sustainable way.

Project
MARE http://www.mare-centre.pt/en ISPA http://www.ispa.pt/ Kids Dive is an educational project that intends to bring ocean literacy to a wide audience of children (8-17 years old). What distinguishes this program from others is that it is performed by scientists and it is 100% practical, including a diving experience. The dive includes educational activities intrinsically related to two workshops presented in the same day: (1) "How to displastify the Ocean" raising questions and solutions on plastic pollution and (2) "Wonders of marine biodiversity" bringing augmented reality to explore the diversity of marine organisms. This educational program is further complemented by a second day visiting a local marine intertidal area, a third day in a guided visit and workshop in Lisbon Oceanarium and a forth day attending the National Geographic Summit, which started in Lisbon (Portugal) in 2017 with an enormous success. To wrap up, a short 5-10 min. documentary is produced for each project edition (60 children) so that they can share their experience with all their colleagues at school and families at home.

Project
Small pelagic fishes (SPF) have extreme ecological and economical importance in marine ecosystems. Nonetheless, SPF are particularly vulnerable to environmental changes, being ectothermic, their performance is highly dependent on aerobic metabolism and on sea surface temperature. In this project, we will implement a multidisciplinary approach to determine the impact of temperature increment on SPF, using the European pilchard Sardina pilchardus as a model-system. We aim to understand the response of two different populations of sardines in terms of metabolic, physiological, reproductive and behavioural responses to climate change. Several questions will be addressed in this proposal: do sardines from different geographic locations have different metabolic, physiological and behavioural responses at increasing temperatures? Does temperature increments affect reproduction? What are the carry-over and acute effects on sardine larvae when exposed to higher temperatures? How will populations? distribution respond to future climate change projections? The adaptation to changing environments and how organisms will respond to climate change are key discussion topics in contemporary biology and this project will contribute with novel and original findings to the study of the biological and ecological adaptation of marine fishes to ocean warming.
