Regulation of gh expression in gilthead sea bream pituitary

This is the 10th volume of Advances in Comparative Endocrinology, a series of books that collect the communications presented at the congresses of the Iberian Association for Comparative Endocrinology (AIEC). This round number marks roughly 20 years since the foundation of AIEC and the beginning of the biennial meetings organized by AIEC affiliated groups. In 2005, our Comparative Endocrinology and Integrative Biology group CEIB-CCMAR organized the 5th AIEC meeting and it was a pleasure to welcome the 12th AIEC Congress back again to Faro, Portugal, in 2019 (26-28 September). Volume X includes contributions resulting from plenary, keynote, oral or poster presentations, and authored by almost 150 senior or young scientists and students, which show the latest advances in the fields of reproduction, energy metabolism, genomics, evolution, stress, immune response and growth in both vertebrates and invertebrates. Studies range from fundamental questions on endocrinology to environmental challenges, animal production and welfare, or the mechanisms of disease, and reach beyond the Iberian borders. In addition to Portugal and Spain, the science presented here comes from institutions in Canada, Chile, France, Norway and USA. About 30% of the communications result from international cooperation, and over 55% were direct collaborations between institutions. AIEC aims to promote collaborations and its congresses are a privileged stage for networking.Supported by funds from the Ministerio de Ciencia, Innovación y Universidades (MICIUN) (AGL2017-89436-R and RTI2018- 100757-B-I00), 2017SGR-1574 and XRAq.
