Temporal and spatial variations in the quality of water in El Gergal Reservior, Seville, Spain [PDF]

open access: yes, 2004
It is often difficult to define ‘water quality’ with any degree of precision. One approach is that suggested by Battarbee (1997) and is based on the extent to which individual lakes have changed compared with their natural ‘baseline’ status. Defining the

Variability of the Deep‐Water Inputs From the Adriatic and Aegean Seas Over the Period of Sapropel S1 Deposition Based on Foraminiferal Nd Isotopes

open access: yesGeophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Deep‐water of the eastern Mediterranean basins mainly forms in the Adriatic Sea and episodically in the Aegean Sea. However, past and future variability under changing temperature and freshwater inputs remains unclear. We reconstruct seawater εNd from Northern Ionian Sea cores to trace intermediate‐ and deep‐water provenance during the ...

Architectural Organization of Dinoflagellate Liquid Crystalline Chromosomes

open access: yesMicroorganisms, 2019
Dinoflagellates have some of the largest genome sizes, but lack architectural nucleosomes. Their liquid crystalline chromosomes (LCCs) are the only non-architectural protein-mediated chromosome packaging systems, having high degrees of DNA superhelicity,

Environmental governance in the face of collapse: The case of Acapulco, Mexico, between tourist splendour and ecological risk

open access: yesEcological Solutions and Evidence, Volume 7, Issue 2, April/June 2026.
Underwater clean‐up efforts in Acapulco Bay reveal the visible consequences of chronic coastal pollution. This study shows how Environmental Risk Assessments (ERAs) can integrate scientific evidence, regulatory frameworks and practitioner experience to identify pollution sources and guide more effective coastal governance in cities of the Global South.

Climate variability in SE Europe since 1450 AD based on a varved sediment record from Etoliko Lagoon (Western Greece) [PDF]

open access: yes, 2017
To achieve deeper understanding of climate variability during the last millennium in SE Europe, we report new sedimentological and paleoecological data from Etoliko Lagoon, Western Greece.

The Evolution of Giant Clam Science: From Foundational Studies to Emerging Frontiers

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
This review synthesizes nearly two centuries of giant clam research, identifying dominant themes, knowledge gaps, and emerging opportunities. Ecology, physiology, aquaculture, genomics, and biomineralization dominate the field, whereas anatomy and biotechnology remain underexplored. Future progress requires stronger integration of genomics, physiology,

Hitchhikers on an Invader: The Parasitic Leech Myzobdella lugubris and the Epibiotic Barnacle Amphibalanus improvisus on the Atlantic Blue Crab Callinectes sapidus in Southwestern Europe

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
This study documents the first worldwide record of the parasitic leech Myzobdella lugubris and the commensal barnacle Amphibalanus improvisus associated with invasive Atlantic blue crabs (Callinectes sapidus) in southwestern Europe. Molecular analyses confirmed the identity of these Western Atlantic native species, highlighting a complex multi‐level co‐

Hypolimnetic anoxia in oligotrophic lakes and its effects on nutrient supply and phytoplankton communities

open access: yesEcosphere, Volume 17, Issue 4, April 2026.
Abstract Low concentrations of dissolved oxygen (DO) in hypolimnetic waters are becoming more common and could affect nutrient supplies available to phytoplankton communities in meso‐ and eutrophic lakes. We examined the connections among hypolimnetic DO, nutrient concentrations, and phytoplankton communities in 26 oligotrophic lakes in the Kawartha ...

The feeding ecology of some zooplankters that are important prey items of larval fish [PDF]

open access: yes, 1984
Diets of 76 species of fish larvae from most oceans of the world were inventoried on the basis of information in 40 published studies. Although certaln geographlc, size- and taxon-specific patterns were apparent, certain zooplankton taxa appeared in the ...
