Abstract Gene flow shapes spatial genetic structure and the potential for local adaptation. Among marine animals with nonmigratory adults, presence or absence of a pelagic larval stage is thought to be key determinant in shaping gene populations. In addition, distribution suitable habitats expected influence biological populations their connectivity patterns. We used whole genome sequencing study demographic history reduced representation (double‐digest restriction associated DNA) data...
Knowledge of the mechanisms limiting connectivity and gene flow in deep-sea ecosystems is scarce, especially for sharks. The Portuguese dogfish (Centroscymnus coelolepis) a globally distributed near threatened shark. C. coelolepis population structure was studied using 11 nuclear microsatellite markers 497-bp fragment from mtDNA control region. High levels genetic homogeneity across Atlantic (Φ(ST) = -0.0091, F(ST) 0.0024, P > 0.05) were found suggesting one large unit at this basin. low...
As human exploration and harvesting moves to the high seas, ecological understanding of deep sea has become a priority, especially in those commercially exploited species whose life cycle, habitat use, demographic structure remain poorly understood. Here we combine otolith trace element stable isotope analyses with microsatellite data investigate population connectivity migratory deep-sea black scabbardfish (Aphanopus carbo), sampled along latitudinal gradient spanning much known range...
Abstract Deep-water sharks are highly diverse, vulnerable, and understudied as a group, despite the increasing pressures on their populations. Twenty-five species of deep-water have been recorded in Azores, an oceanic archipelago mid-North Atlantic, that regularly caught bycatch hook-and-line fisheries. Avoiding presents multiple challenges due to high catchability, difficulties correctly identifying species, general lack data these species. This review summarizes findings recent studies...
Trait-based approaches that complement taxonomy-based studies have increased in popularity among the scientific community over last decades. The collection of biological and ecological characteristics species (i.e., traits) provides insight into ecosystem vulnerability to environmental anthropogenic changes, as well functioning. Here, we present FUN Azores trait database, describe our approach, evaluate its scope, compare it other marine databases, explore spatial distribution traits with...
Abstract Introduction Adult-onset autoimmune diabetes (AID) has two different phenotypes: classic type 1 mellitus (T1DM), with insulin requirement just after diagnosis, and latent in adults (LADA). The purpose of this study is to characterize patients AID followed on a tertiary centre, comparing T1DM LADA. Methods We collected data from positive islet autoantibodies, aged 30 years old over at diagnosis. Patients who started the first 6 months were classified as no requirements Data regarding...
The American Diabetes Association proposed two subcategories for type 1 diabetes mellitus: 1A or immune-mediated (IDM) and 1B idiopathic diabetes. absence of β-cell autoimmune markers, permanent insulinopenia prone to ketoacidosis define the second category, whose pathogenesis remains unclear. Only a minority patients fall into this also designated non-immune-mediated (NIDM), which is considered by several authors similar 2 aim study evaluate differences at diagnosis 10 years later...
A comparison of the genetic structure Chimaera monstrosa populations from Atlantic Ocean and Mediterranean Sea was carried out using mitochondrial DNA analysis. Results indicate high significant pairwise Φ ST values with no shared haplotypes between two areas. Furthermore, migration rate estimates suggested absence gene flow basins. These findings, coupled species vertical distribution, suggest that shallow depth Strait Gibraltar may act as a barrier limiting dispersal capabilities these...
Population genetic studies of species inhabiting the deepest parts oceans are still scarce and only until recently we started to understand how oceanographic processes topography affect dispersal gene flow patterns. The aim this study was investigate spatial population structure bathyal bony fish Coryphaenoides mediterraneus, with a focus on Atlantic-Mediterranean transition. We used nine nuclear microsatellites mitochondrial cytochrome c oxidase I from 6 different sampling areas. No found...
According to the most recent taxonomical revision, deep-sea dogfish genus Deania encompasses four species. Three of them, D. calcea, profundorum , and hystricosa occur in North Atlantic. Whilst can be identified by presence a subcaudal keel, other two species are not easily visually distinguished. Uncertainties over identification raises concerns stock units whether management plans adequate. In this study we compared onboard visual specimens, with morphological inspection skin denticles...
The value of interdisciplinarity for solving complex coastal problems is widely recognized. Many early career researchers (ECRs) therefore actively seek this type collaboration through choice or necessity, professional development project funding. However, establishing and conducting interdisciplinary research collaborations as an ECR has many challenges. Here, we identify these challenges the lens ECRs working in different disciplines on a common ecosystem, Norwegian Skagerrak coast. most...
Chondrichthyans (sharks, rays and chimeras) are a fascinating highly vulnerable group of early branching gnathostomes. However, they remain comparatively poorly sampled from the point view molecular resources, with deep water taxa being particularly data deficient. The development long-read sequencing technologies enables analysis phylogenetic relationships through precise reliable assembly complete mtDNA genomes. characterization mitogenome opal chimera Chimera opalescens Luchetti, Iglésias...
The recognition that deep-water sharks are among the most vulnerable marine species to fisheries exploitation led implementation of fishing prohibition regulations in European waters. Reducing unwanted bycatch and mortality key mitigation measure for conservation these species. Yet, few studies have investigated how mitigate common on longline fisheries. Specifically, potential hook type as such a has never been investigated. Here, we conducted experiments test circle hooks affect...
Summary Pituitary infections, particularly with fungus, are rare disorders that usually occur in immunocompromised patients. Cushing’s syndrome predisposes patients to infectious diseases due their immunosuppression status. We report the case of a 55-year-old woman, working as poultry farmer, who developed intense headache, palpebral ptosis, anisocoria, prostration and psychomotor agitation 9 months after initial diabetes mellitus diagnosis. Cranioencephalic CT scan showed pituitary lesion...
Abstract The presence of the opal chimaera, Chimaera opalescens , is reported for first time in deep waters Azores, with capture four specimens by fishermen and video recording an additional five individuals. Species identification was supported 646 bp sequenced fragment mitochondrial gene cytochrome oxidase subunit I. Because C. a recently recognised species that had been recurrently misidentified as rabbitfish, monstrosa historical data Azores were reviewed to assess possible both region....
