An updated list is presented of the alien species in the transport or introduction invasion stage in inland waters of the Iberian Peninsula. The list is based on a systematic assessment of information in collaboration with a wide expert team from Spain and Portugal. This list is an important tool to support the implementation of the IAS Regulation, particularly in prevention measures and in the development of a...
Se presenta una lista actualizada de las especies exóticas invasoras que se encuentran en la etapa de transporte o de introducción en aguas continentales de la Península Ibérica. La lista se basa en una evaluación sistemática de la información en colaboración con un amplio equipo de expertos de España y Portugal. Esta lista es un instrumento importante para la aplicación del Reglamento de la Unión Europea (UE) ...

Mangroves act as buffer areas for marine systems, providing a barrier to contamination from continental sources by retaining metal pollutants. This study evaluates metal and semimetal contamination in the water column and sediments of four mangroves located on the volcanic island of São Tomé. Several metals had a widespread distribution, with occasional high concentrations, linked to potential sources of contam...
Different invertebrate groups are often exploited on sediment shores and mudflats, including poly- chaetes, sipunculids, bivalves and crustaceans. The commercial importance of polychaetes and sipun- culids, that has increased in the early 2000's because of its use as a food source for the aquaculture sector and a growing demand of worms for use as sea angling bait, seems to be declining nowadays. In Portugal bai...
DNA barcoding has the potential to overcome taxonomic challenges in biological community assessments. However, fulfilling that potential requires successful amplification of a large and unbiased portion of the community. In this study, we attempted to identify mitochondrial gene cytochrome c oxidase I (COI) barcodes from 1024 benthic invertebrate specimens belonging to 54 taxa from low salinity environments of ...
Jellyfish modulate the energy fluxes between compartments of aquatic ecosystems and the period that energy remains within each compartment. However, the contribution of different sources of organic matter (OM) to the production of most estuarine jellyfish species is unknown. Therefore, this study aimed to identify and quantify the putative sources of OM for Blackfordia virginica (Cnidaria, Hydrozoa) Mayer, 1910...
