Low-Cost Citizen Science Effectively Monitors the Rapid Expansion of a Marine Invasive Species

João Pedro da Silva Encarnação finished his PhD in Marine Science in 2024 at the University of Algarve, merging scientific knowledge on invasive species with contribution from citizen science. His current research topics include marine invasive species, as the Atlantic blue crab and the weakfish, tropicalization and redistribution of species in coastal areas, while improving the collaboration between academia and society with citizen science in the study and management of biological invasions in the marine environment. So far has published 10 peer-reviewed scientifc articles as first author and 10 others as co-author. Has participated in several national and international projects and scientific expeditions, and contributed with photographs to 7 books. Founder and coordinator of the NEMA citizen science campaign: www.NEMAlgarve.com.

POSTCARD FROM QUELIMANE (ZAMBÉSIA, Mozambique)

Francisco Leitão, Alexandra Teodósio and João Encarnação went to Quelimane, Moçambique to participate in the kickoff of the project BioFISH.

Nos últimos anos, os investigadores do Centro de Ciências do Mar (CCMAR) reportaram o aparecimento de mais de uma dezena de espécies invasoras no estuário do Guadiana. A nova espécie detetada é um hidróide, que ao incrustar-se em estruturas artificiais traz efeitos negativos não só a nível do ecossistema, mas também a nível sócio-económico.

Os investigadores do Centro de Ciências do Mar (CCMAR) descobriram no estuário do Guadiana um valioso recurso pesqueiro: o caranguejo-azul, uma espécie característica da América do Norte, que agora vive a mais de sete mil quilómetros de casa.

A espécie é nativa da costa leste da América do Norte, mas foi encontrada pela primeira vez no estuário Guadiana na passada semana por pescadores de Vila Real de Santo António, e identificada por dois investigadores do Centro de Ciências do Mar (CCMAR).

A corvina americana, ou corvinata, não é natural de águas nacionais, mas mesmo tratando-se de uma espécie invasora já está instalada nos estuários dos nossos rios. Por isso, os investigadores do CCMAR vão dar a conhecer numa prova de degustação, de que forma se pode consumir este peixe e assim tentar aliviar a pressão que esta espécie faz nos nossos recursos pesqueiros.

Records of tropical and sub-tropical species in the Portuguese Southwest coast points to a poleward shift in species distribution.

João Encarnação will be assessing the present distribution of new species across the Algarve coast.

CCMAR celebrated 29 years of foundation and announced the winners of the "Aos olhos do CCMAR" contest with the aim of promoting and disseminating the scientific works of our researchers.

CCMAR's NEMA project participates with the organization of two Underwater FotoBlitz. The initiative takes place across the country from 10 to 18 October.

Biological invasions are one of the many consequences of a globalized world. Thus, early detection and eradication of invasive species are crucial to prevent significant economic impacts.

From May 29 to June 6, the National and Iberian Week on Invasive Species occurs. The NEMA project participates in this week in collaboration with the recognized Algarvian Chef and Michelin star winner Chef Leonel Pereira.

The challenge set by our researchers is to find and photograph the fireworm in the Algarve waters. The underwater Fotoblitz is organised by the NEMA (New Marine Species of the Algarve) platform and takes place from 14 August in five different locations.
