Study identifies 231 non-indigenous marine species in Portugal

Barlavento28 August 2026 at 12:55

A new national inventory identified 231 non-indigenous marine species in Portugal, confirming the presence of these organisms in Portuguese waters. This study represents an important update to the knowledge about the country's marine biodiversity.

Among the catalogued species, five had never been previously recorded in Portuguese territory, expanding scientific knowledge about the introduction of species on the national coasts.

The inventory was published by Barlavento and constitutes an essential tool for the monitoring and tracking of non-indigenous marine species that have colonized Portuguese ecosystems.

Nepal, Glacier Collapse, Global Warming and Man

A glacier collapse in Nepal, occurring on August 26, 2026, was apparently caused by global warming and generated a seismic signal equivalent to a magnitude 5.2 earthquake, according to the United States Geological Survey (USGS). The article explores the relationship between glacier collapse, climate change, and human responsibility in these increasingly frequent geological phenomena.

Sines Port among strategic points for the entry of non-indigenous marine species in Portugal

A scientific study led by MARE and ARNET identified Sines Port as one of the strategic zones for the entry of non-indigenous marine species in Portugal, accounting for 231 confirmed species in national waters, an increase of about 75% compared to the 133 identified a decade ago. The research, published in Marine Pollution Bulletin and involving 31 researchers from 11 universities, points to navigation as the main pathway of introduction, through ballast water and organisms attached to ship hulls. In mainland Portugal, 39% of species originate from the North Pacific. Researchers warn of the need for monitoring and prevention in port areas such as Sines, due to intense shipping activity and its inclusion in major international routes.
