Field comparison of sardine post-flexion larval growth and biochemical composition from three sites in the W Mediterranean (Ebro river coast, bays of Almería and Málaga)

open access: yesScientia Marina, 2006
Late larval stages of sardine (16-23 mm) were sampled during the 2003 spawning season in their nursery grounds located off the Ebro river mouth, on the Catalan coast, and in two bays of the Alborán Sea coasts, the Bay of Almería and the Bay of Málaga ...

Linking biosurface reactivity and photosynthesis to investigate Sphagnum mosses as ecosystem engineers

open access: yesNew Phytologist, EarlyView.
Habit photographs of field‐collected and in vitro‐cultivated (c) Sphagnum spp. used for experiments. Summary Sphagnum mosses regulate peatland carbon storage, hydrology, nutrient cycling, and ecosystem functioning. However, the links among their surface chemistry, photosynthesis, responses to submersion and pH remain poorly understood.

The Zooplankton International Geospatial dataset: A global repository of spatiotemporal freshwater zooplankton community composition data from lakes and reservoirs to support ecological research

open access: yesLimnology and Oceanography Letters, Volume 11, Issue 5, September 2026.
Abstract Zooplankton transfer substantial energy in aquatic food webs and are used as indicators of environmental change. Syntheses of zooplankton community dynamics globally require datasets that span a wide range of environmental gradients; however, these datasets are limited due to methodological differences across programs, taxonomic ...

Reproductive biology of black hakes (Merluccius polli and M. senegalensis) off Mauritania

open access: yesCiencias Marinas, 2011
Black hake, Merluccius polli and M. senegalensis, are demersal species that inhabit the continental shelf and upper slope off Morocco, Mauritania, and Senegal, and are targeted by Spanish trawlers and bottom longliners. Merluccius senegalensis generally

Spatial Strategies in Coral Transplantation: A Systematic Review of Clustered Versus Widespread Configurations

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 8, August 2026.
ABSTRACT Active coral reef restoration incorporates ecological engineering principles. Yet, the spatial arrangement of transplanted colonies, one of the few design parameters directly controlled by practitioners, remains poorly explored empirically. We conducted a systematic review following PRISMA guidelines to evaluate how clustered (high‐density ...

Metal contamination in Portman Bay (Murcia, SE Spain) 15 years after the cessation of mining activities

open access: yesCiencias Marinas, 2008
To evaluate the state and temporal trends of the residual metal contamination caused by the dumping of mine tailings into Portman Bay (SE Spain) during the 20th century, concentrations of Hg, Cd, Pb, Cu, Zn, and As in wild mussels (Mytilus ...

Submarine Flank Collapses at Tagoro Volcano: Insights From Bathymetric Surveys and 3D Multiphase Simulations

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.
Abstract Volcanic islands are prone to flank instabilities that can generate tsunamis even when mobilized volumes are moderate. This study investigates submarine collapses during the 2011–2012 eruption south of El Hierro, which built the Tagoro submarine volcano.

GEOGRAFIA MARINHA - A RETOMADA DO ESPAÇO PERDIDO

open access: yesRevista da ANPEGE, 2017
Durante a fase de exploração do século 19 a oceanografia se encontrava firmemente enraizada na geografia. Com o aumento da necessidade de estudos mais detalhados e quantitativos a oceanografia teve que se especializar e subdividir nas suas diferentes ...

Transient Ecological Niches for Diazotrophs in Upwelling Bays

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.
Abstract Diazotrophs, microorganisms capable of fertilizing the ocean through biological nitrogen fixation (BNF), are widespread in the oceans, including upwelling bays. However, their ability to respond to short‐lived upwelling pulses, lasting only a few days, remains poorly understood. To investigate diazotrophy across temporal scales, we analyzed 18
