Biological interactions between fish and jellyfish in the northwester Mediterranean

Tilves Matheu, Uxue (Date of defense: 2019-05-16)

Jellyfish are important components of marine ecosystems, being a key link between lower and higher trophic levels. Jellyfish blooms occur sporadically and unpredictably in coastal areas and often have important socio-economic ...

Biology, ecology and ecophysiology of the box jellyfish Carybdea marsupialis (Cnidaria: Cubozoa) = Biologia, ecologia i ecofisiologia de la cubomedusa Carybdea marsupialis (Cnidaria: Cubozoa)

Acevedo Dudley, Melissa Judith (Date of defense: 2016-10-24)

Over the last years, the sightings of the cubomedusa Carybdea marsupialis have increased in the Mediterranean Sea and this has been linked to an increase in its abundance. Consequently, this phD thesis addresses some ...

Citizen sciences technologies for operational monitoring of aquatic ecosystems

Rodero García, Carlos (Date of defense: 2023-05-29)

(English) Light attenuation is a critical factor in aquatic ecosystems for many physical and biological processes. Water transparency plays an essential role in understanding the variations of the ecological environment ...

In situ direct study of filtration and respiration rate of Mediterranean sponges = Estudio in situ de la filtración y la respiración de esponjas mediterráneas

Morganti, Teresa Maria (Date of defense: 2016-07-27)

Sponges play important roles in the functioning of marine ecosystem in which they are abundant. These roles range from stabilizers of substrate, to acting as major link between benthic and pelagic realms by filtering large ...

Population dynamics, interactions and evolution of marine microbes using genomic approaches

Latorre Pérez, Francisco (Date of defense: 2023-02-03)

(English) There is a myriad of microorganisms on Earth contributing to global biogeochemical cycles. In the surface ocean, the smallest microbes (picoplankton) are responsible for an important fraction of the total atmospheric ...

Return of the marine heterotrophic flagellates: diversity, distribution and gene expression patterns

Obiol Plana, Aleix (Date of defense: 2023-01-27)

(English) Marine heterotrophic flagellates (HF) are very small (2-5 µm) unpigmented protists that are dominant bacterial grazers in the ocean, where they link the transfer of carbon from bacterial cells to higher trophic ...
