Subtropical gyres are the oceanic regions where plastic litter accumulates over long timescales, exposing surrounding islands to contamination, with potentially severe consequences on marine life. Islands' exposure such contaminants, littered distances in or terrestrial habitats, is due ocean currents that can transport ranges. Here, this issue addressed for Easter Island ecoregion (EIE). High-resolution circulation models used a Lagrangian particle-tracking tool identify connectivity...
Two short biophysical surveys were carried out in order to assess how the decapod crustacean larvae vertical distribution and circulation patterns an equatorward facing embayment (Gulf of Arauco, 37° S; 73° W) influenced larval transport into Gulf. The is located at upwelling area south central Chile features a deep (∼60 m) shallow (∼25 pathway communication with adjacent coastal ocean. Profiles zooplankton, temperature, salinity, dissolved oxygen current velocity measured during 22-h period...
In high altitude environments, extreme levels of solar radiation and important differences ionic concentrations over narrow spatial scales may modulate microbial activity. Salar de Huasco, a high-altitude wetland in the Andean mountains, diversity communities has been characterized associated with strong environmental variability. Communities that differed light history conditions, such as nutrient salinity from different locations, were assessed for bacterial secondary production...

Pleuroncodes monodon is a conspicuous component of the Humboldt Current ecosystem. Benthic adults south ∼22°S are associated with low temperature (T) ∼11°C and dissolved oxygen (DO) (<0.5 mL L−1) waters during hatching period. Because P. mondon inhabits an minimum zone larval release assumed to match most favorable environmental conditions, performance under cold hypoxic conditions its implications have not yet been assessed experimentally. We quantitatively effect DO T within ranges,...
Cyanobacterial toxic blooms are a worldwide problem. In Rio de la Plata basin, anthropic eutrophication and dam construction have promoted an increase in cyanobacteria blooms, especially those of the Microcystis aeruginosa complex (CMA). Here, we describe exceptional observed summer 2019 on coast Río Atlantic Uruguay. We discuss main driving mechanisms using biological, meteorological oceanographic sampling data, satellite images reanalysis. The covered wide surface (Carmelo to Rocha; 500...

In marine benthic ecosystems, larval connectivity is a major process influencing the maintenance and distribution of invertebrate populations. Larval complex to study as it determined by several interacting factors. Here we use an individual-based, biophysical model, disentangle effects such factors, namely vertical migration, growth, mortality, adults fecundity, habitat availability, for gastropod Concholepas concholepas (loco) in Chile. Lower transport success higher dispersal distances...
Understanding patterns of marine connectivity in oceanic islands is a fundamental element for conservation and management fished species. In the present study, level endemic lobster Panulirus pascuensis Reed, 1954 from remote southern Pacific Ocean was estimated, focusing on Motu Motiro Hiva Marine Park (MMH), considered here as source recruits to Easter Island. The adult populations between Eastern Island (EI) Salas y Gomez (SG), center MMH, studied by quantifying reciprocal migration rates...
The knowledge on the mechanisms of population connectivity through larval stages and its implications across time spatial scales is crucial to assess possible biological outcomes marine protected areas (MPA) network designs. We re-analyzed available data meroplankton distribution in Rapa Nui ecoregion around Easter Island (27° S, 109°22′ W) Salas y Gómez (26°28′S, 105°21′W) together with situ satellite physical information evaluate for populations connectivity. geostrophic flow near coast...
