Living resources in the sea are essential to economic, nutritional, recreational, and health needs of billions people. Variation biodiversity that characterizes marine systems, which underlies numerous ecosystem services provided humans, is being rapidly altered by changing environmental factors human activity. Understanding underlying causes these patterns, forecasting where future changes likely occur, requires monitoring patterns organism abundance, diversity, distribution health;...
Abstract This article documents the addition of 83 microsatellite marker loci and 96 pairs single‐nucleotide polymorphism ( SNP ) sequencing primers to Molecular Ecology Resources Database. Loci were developed for following species: Bembidion lampros, Inimicus japonicus, Lymnaea stagnalis, Panopea abbreviata, Pentadesma butyracea, Sycoscapter hirticola Thanatephorus cucumeris anamorph : Rhizoctonia solani) . These cross‐tested on grandifolia reyndersii also primer 88 allele‐specific or...
Abstract Butyltins (BTs), polyaromatic hydrocarbons (PAHs), organochlorine pesticides (OCPs), and polychlorinated biphenyls (PCBs) were assessed in a mid‐latitude environment of the Patagonian coast, distant from significant pollutant sources. Bioaccumulation processes through bottom sediment resuspension suggested by BTs level (expressed as ng tin [Sn] g –1 dry wt) found surface (<limit detection [LOD]–166.5 bivalve mollusks (29.4–206.0 wt); whereas imposex incidence was only 15%...
Tributyltin (TBT) and other pollutants are present in Patagonia, associated with maritime traffic human activities. Cause–effect relationship between TBT imposex development females of marine gastropods is well documented. We tested whether the incidence pollution related to detectable shell-shape variations edible snail (Buccinanops globulosus). compared shell shape B. globulosus six contiguous sites on a gradient traffic, by using geometric morphometric analysis. Our results indicated that...
Abstract Aim We evaluated whether patterns of species diversity (α, β and γ) rocky shore assemblages followed latitudinal gradients (i.e. LDGs) along the South American coasts, tested hypotheses related to potential processes sustaining or disrupting expected LDG pattern at various spatial scales. Location Coasts America. Taxon Macroalgae sessile/slow‐moving macrofauna on intertidal shores. Methods changes in composition across 143 sites. The degree replacement loss different scales regions...
Marine Protected Areas (MPAs) require efficient monitoring tools to assess habitats and biodiversity, particularly in remote or understudied regions. This study demonstrates the utility of towed video-diver technique combined with high-resolution video for rapidly surveying benthic associated taxa. Applied Arredondo, a shallow bay within an MPA Atlantic Patagonia, method covered 14,000 m2 through eight transects, utilizing just 180 min dive time ~300 analysis. Substrate types their taxa were...
Assemblages associated with intertidal rocky shores were examined for large scale distribution patterns specific emphasis on identifying latitudinal trends of species richness and taxonomic distinctiveness. Seventy-two sites distributed around the globe evaluated following standardized sampling protocol Census Marine Life NaGISA project (www.nagisa.coml.org). There no clear estimators along gradients or among Large Ecosystems (LMEs); however, a strong gradient in composition (i.e.,...
Butyltins (BTs) were found in sediments and body tissues of the edible gastropod Odontocymbiola magellanica, which imposex has been recorded since 2000. BTs ranged from < MDL to 174.8 ng (Sn) g−1 for TBT, 19.2 DBT, 71.8 MBT. In varied 147.1, 77.0 345.3 DBT MBT, respectively. BT concentrations higher gonads digestive glands than albumen gland foot (edible). The highest both gastropods harbour area, decreasing with distance areas less maritime traffic.

Large-scale patterns of encapsulated embryo development and causal factors determining developmental success in the marine environment have been relevant issues research for decades. We studied embryonic intracapsular oxygen availability Trophon geversianus egg capsules from northern Patagonia (Golfo Nuevo, Argentina). The had a mean duration 112 days (at 12–14°C). initial number eggs per capsule was 197 (mean diameter 270 µm), but on average only four embryos reached juvenile stage. Embryos...
The rocky shore of Punta Este, Golfo Nuevo (Patagonia, Argentina), was sampled by means the standardized NaGISA (CoML) protocol, that aimed to generate biodiversity baseline data in six levels, from high intertidal 10 m depth. Based on generated data, we analysed benthic assemblage structure, species richness, mean abundance and distribution pattern invertebrate functional groups, typifying each subtidal level. is exposed extreme physical conditions higher than any other system studied, with...
Gastropod assemblages from nearshore rocky habitats were studied over large spatial scales to (1) describe broad-scale patterns in assemblage composition, including by feeding modes, (2) identify latitudinal pattern of biodiversity, i.e., richness and abundance gastropods and/or regional hotspots, (3) potential environmental anthropogenic drivers these assemblages. Gastropods sampled 45 sites distributed within 12 Large Marine Ecosystem regions (LME) following the NaGISA (Natural Geography...
High concentrations of metals are accumulated by edible marine resources, affecting human health. Marine gastropods have been commercially captured and consumed in Argentina for decades without official regulations or studies to guarantee their safety. In this study, (cadmium, aluminium, iron, zinc, copper lead) were analysed the first time Buccinanops globulosus, Adelomelon ancilla Trophon geversianus surrounding sediments. Taking into account maximum levels recommended national...
Acquiring marine biodiversity data is difficult, costly, and time-consuming, making it challenging to understand the distribution abundance of life in ocean. Historically, approaches sampling over large geographic scales have advocated for equivalent effort across multiple sites minimize comparative bias. When cannot be equalized, techniques such as rarefaction been applied biases by reverting diversity estimates numbers samples or individuals. This often results oversampling wasted...
Underwater sampling needs to strike a balance between time-efficient and standardized data that allow comparison with different areas times. The roving diver survey involves divers meandering actively searching for species has been useful producing fish lists but seldom implemented benthic taxa. In this study, we used non-destructive technique register associated kelp forests at the sub-Antarctic Bécasses Island (Beagle Channel, Argentina), detecting numerous while providing first multi-taxa...
Abstract. Members of Odontocymbiola magellanica (Volutidae, Odontocymbiolinae) inhabit Argentinean waters from 35°S to the Magallanes Strait. The reproductive biology this potential fishery resource has not been studied before. Male individuals reach maturity at 80 mm and females 90 mm, corresponding ∼7 8 years age, respectively. Mating was observed in field all seasons possess live spermatozoa bursa copulatrix year round, suggesting that living sperm can be preserved for several months....
