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 other an anti-tropical distribution, with decreasing towards tropics. distribution pattern these clades been explained as consequence secondary contact...
Climate change often leads to shifts in the distribution of small pelagic fish, likely by changing match-mismatch dynamics between these sensitive species within their environmental optima. Using present-day habitat suitability, we projected how different scenarios climate (IPCC Representative Concentration Pathways 2.6, 4.5 and 8.5) may alter large scale European sardine Sardina pilchardus (a model species) 2050 2100. We evaluated variability species-specific optima allowing a comparison...
Anthropogenic pressures on marine ecosystems are increasing worldwide, causing loss of biodiversity and ecosystem functioning, driving species towards risk extinction. To protect vulnerable habitats, Marine Protected Areas (MPAs) increasingly established worldwide as conservation measures. Seahorses act flagship for coastal due to their charismatic appearance high vulnerability habitat degradation. Here, the suitability two European seahorse species, Hippocampus hippocampus guttulatus, was...
ABSTRACT Different plastics require specific recycling methods, but mixing various types can complicate their together. In this study, an innovative method for mixed was developed, based on the principle of dissolution–precipitation, focusing a plastic mixture typically found in bins. Initially, different solvents were employed to dissolve polymers individually being dissolution extent determined. Using data, together with solubility parameters, including Hildebrand coefficients and others,...
Abstract Aim As part of an emerging effort to understand the role played by climatic fluctuations in shaping geographical distributions and abundances marine organisms, we examined genetic patterns leading‐edge populations European anchovy, Engraulis encrasicolus , its American counterpart, morphologically similar silver eurystole North Atlantic Ocean. Location Adults were collected from western Atlantic, eastern (from Norway Ghana) Mediterranean. Methods A 1045 bp fragment mt DNA cytochrome...
Abstract Climate change is restructuring biodiversity on multiple scales and there a pressing need to understand the downstream ecological genomic consequences of this change. Recent advancements in field eco‐evolutionary genomics have sought include evolutionary processes forecasting species' responses climate (e.g., offset), but date, much work has focused terrestrial species. Coastal offshore species, fisheries they support, may be even more vulnerable than their counterparts, warranting...
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 sardine Sardina pichardus Atlantic Ocean and Mediterranean Black Seas, projected climate-driven changes suitable areas from 2050-2099 under IPCC – RCP 8.5 scenario. Sea surface temperature distance to coast had greater influences habitats, reflecting temperature-...
The establishment of high-throughput sequencing technologies and subsequent large-scale genomic datasets has flourished across fields fundamental biological sciences. introduction resources in fisheries management been proposed from multiple angles, ranging an accurate re-definition geographical limitations stocks connectivity, identification fine-scale stock structure linked to locally adapted sub-populations, or even the integration with individual-based biophysical models explore life...
Temperature is a determinant cue for several behavioral, physiological, and metabolic processes in fish, which occur within range set to optimize species fitness. Understanding how ocean warming will impact species, at individual population levels, is, therefore, of utmost relevance management conservation purposes. This knowledge assumes particular when it comes with unique life history traits that experience multiple threats, such as seahorses. study aimed assess the effects on growth,...
Ongoing climatic changes, with predictable impacts on marine environmental conditions, are expected to trigger organismal responses. Recent evidence shows that, in some species, variation mitochondrial genes involved the aerobic conversion of oxygen into ATP at cellular level correlate gradients sea surface temperature and dissolved oxygen. Here, we investigated adaptive potential European sardine Sardina pilchardus populations offshore Iberian Peninsula. We performed a seascape genetics...

These sharks closely resemble each other, have overlapping geographical ranges are difficult identify by morphological characters. Non‐metric multidimensional scaling variables indicates a clear...
Ecological niche modelling (ENM) determines habitat suitability of species by relating records occurrence to environmental variables. Here, we investigated four terrestrial slugs the genus Geomalacus from Iberian Peninsula using ENM. The potential distribution these was estimated maximum entropy modelling. For this used published presence records, together with observations our fieldwork, and 10 layers variables in a crossvalidation design 'minimum predicted area' as measure success. each...
Accurate collection of biometric data is important for understanding the biology and conservation marine organisms, including elasmobranch teleost fish, both in nature controlled environments where monitoring specimens' health mandatory. Traditional methods involving specimen capture handling are invasive, stressful, disruptive. Some techniques like underwater visual census or laser photogrammetry have been used noninvasive collection, but they limitations biases. The application...
Abstract 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 understand genetic patterns connectivity of fish between Atlantic Pacific basins. We surveyed 16 locations worldwide using mtDNA 8 microsatellite loci for parameters, (cyt b ; 16S) nuclear (RAG1; RAG2) regions dating major lineage-splitting events within Engraulidae family. The OWA divergences (0–0.4%) are...
Objetivo: Analisar as técnicas cirúrgicas terapêuticas empregadas em pacientes com apendicite aguda. Métodos: Trata-se de uma revisão integrativa, artigos publicados entre 2014 e 2024 nas línguas portuguesa, inglesa espanhola o conteúdo disponibilizado na íntegra.

The earth's climate system and the global ocean have been warming up, since mid-twentieth century it is expected that ocean's temperature will rise in next years even more [1], [2], [13], [25], [28]. For ectotherms, such as fish, a determinant cue for several behavioural [29], physiological [24], metabolic processes [6]. Seahorses' particular life history makes them vulnerable to human or natural disturbances [17]. long snout seahorse, Hippocampus guttulatus, one of two species inhabit...
The European anchovy has been the focus of numerous population genetic studies, most which exposing high levels haplotype diversity. However, Keskin and Atar (2012) revealed rather singular results null diversities. We therefore call for caution when considering these findings.
