Mediterranean Sea invaded by alien species
Date:5/23/2011

en species that have recently been introduced. The pufferfish toxin, tetrodotoxin, causes muscle paralysis, which can lead to respiratory arrest. In the worst case the outcome can be fatal. In the coastal environments that Kalogirou has studied, the pufferfish has become a dominant species, which has led to both ecological and social effects.

"There does seem to be an awareness at the European level of how quickly species spread into new areas, but there is a lack of basic knowledge of monitoring methodology, specific life characteristics of alien species and risk assessments. The impact of alien species, known as biological contamination, is something that must be taken into account in environmental impact assessments,"Kaligirou notes.
