Ecology and Evolution, Volume 16, Issue 3, March 2026.European sprat can be divided into distinct genetic groups in the NE Atlantic, that is, Norwegian fjords, Baltic Sea and an oceanic component. The species has been increasingly reported in Icelandic waters since 2017. To investigate the source of introduction, Icelandic sprat has been genotyped and analyzed in comparison with existing reference data ...

Assessing ballast treatment standards for effect on rate of establishment using a stochastic model of the green crab [PDF]
, 2012 This paper describes a stochastic model used to characterize the probability/risk of NIS establishment from ships' ballast water discharges. Establishment is defined as the existence of a sufficient number of individuals of a species to provide for a ...

Ecology and Evolution, Volume 16, Issue 3, March 2026.We report the first record of a non‐native hermatypic coral in Venezuela, exhibiting biological traits characteristic of invasive species. The coral is a member of the genus Acropora (Scleractinia: Acroporidae), native to the Indo‐Pacific. This non‐native petrous coral occurred in a reef of the Morrocoy National Park, in the southern Caribbean.

Role of Reporting in Compliance Monitoring and Enforcement of Ballast Water Management
ASEAN Journal on Science and Technology for Development, 2018 The Decision Support System (DSS) for ballast water management in any given port is dependent on the availability of information on ballast water carried by a ship in advance. Collation of information through Ballast Water Reporting Forms (BWRF) has been
