FOLLOW IT BY STREAMING 

(link available on the day of the broadcast)

The “Meetings Espresso” son the formato of talks that have been taking place in the IIM-CSIC with the aim of getting to know each other better between nós,to better understand the activity carried out at our centre and explore the world of marine science, encouraging scientific and technical discussion and strengthening links between groups onde both research and technical staff can take part for share their work, experiences and results.

Son events designed especially for the our staff, but everyone is invited the join through our streaming broadcast.

This new formato will be held every two weeks, to the 10:00 hours in the Assembly Hall of the IIM-CSIC will be accompanied by complimentary coffee (“Espresso”) for favorecer the bo fluír of the communication.

Desta vez encontrámonos with the our compañeira, Natalia Petit, of the Group of Ecoloxía and Marine resources

“Sustainable fisheries the largo plazo in the environment cambiante: integrando the genética of poblaciones the sciences pesqueras”.

The cambios in the condicións físicas, químicas and biolóxicas of the hábitats marine, orixinados by diversas activities humanas (é dicir the Global Change), complican the avaliacións necesarias for garantir the sustainability the longo prazo of the resources pesqueiros natural. For prosperar, the species marine deben adaptarse to the new condicións ambientais mediante the proceso of selección natural, that utiliza the variabilidade xenética presente in the poboacións of the species the materia prima.

With all, the episodios of sobreexplotación xeran diminucións in the tamaños of the poboacións, reducindo proporcionalmente the their niveis of diversidade xenética and, potencialmente, the capacidade of the species for adaptarse the cambios in the environment. THE xenética of the poboacións é the disciplina encargada of investigar the cambios in the niveis and patróns of diversidade xenética of the poboacións, proporcionando the marco teórico sólido for evaluate tanto the posible perda of variabilidade xenética by explotación the tempo necessary for the its recuperación.

Desta maneira, the inclusión of the xenética of poboacións in the avaliacións of the marine resources explotados é of suma importance and urxencia for garantir the sustainability the longo prazo destes resources.

Natalia Petit-Marty 

Xenetista and bióloga evolutiva. Obtivo the its Licenciatura in Xenética in 1999 in Arxentina, onde also iniciou the its carreira researcher abordando temas relacionados with the xenética of poboacións of insectos infestas. In 2003, trasladouse the Spain and comezou the its tese doutoral in xenética of poboacións and evolución molecular, in the marco of the programme of doutoramento in Xenética of the University Autónoma of Barcelona, obtendo the grao of Doutor with máxima cualificación in 2008.

Between 2009 and 2013, levou the cabo various projects, mainly centrados in the xenómica of poboacións of species of primates, the researcher postdoutoral in the Institute of Bioloxía Evolutiva of Barcelona. In 2014, estableceuse in the Illa of Menorca, onde traballou of forma independente, focalizándose mainly in temas relacionados with the conservación marine. In 2019, trasladouse the Hong Kong for desempeñarse the researcher postdoutoral in the Swire Institute of Marine Science of the University of Hong Kong, onde desenvolveu projects relacionados with the mecanismos of adaptación of species marine to the cambios in the condicións of the sea. Finally, in 2022, obtivo the posición postdoutoral financiada polthe actions Marie Skłodowska-Curie (MSCA) for traballar in the Project “Potencial adaptativo to the change in the condicións of the environment in species of fish explotadas” in the Institute of Marine Research (IIM -CSIC) in Vigo, the cal é the its posición current.

Natalia publicou vinte and four artigos scientific, sendo the autora main in once deles; colaborou in different projects scientific the nivel national and international and participa activamente in activities of science outreach for concientizar on the vulnerabilidade of the marine environment to the activities humanas.
