Deciphering mollusc shell production: the roles of genetic mechanisms through t...
Clark, Melody S.; Peck, Lloyd S.; Arivalagan, Jaison; Backeljau, Thierry; Berland, Sophie; Cardoso, João CR; Caurcel, Carlos; Chapelle, GauthierMost molluscs possess shells, constructed from a vast array of microstructures and architectures. The fully formed shell is composed of calcite or aragonite. These CaCO3 crystals form complex biocomposites with proteins, which although typically less than 5% of total shell mass, play significant roles in determining shell microstructure. Despite much research effort, large knowledge gaps remain in how molluscs ...
Revealing higher than expected meiofaunal diversity in Antarctic sediments: a m...
Fonseca, V. G.; Sinniger, F.; Gaspar, J. M.; Quince, C.; Creer, S.; Power, Deborah M.; Peck, Lloyd S.; Clark, Melody S.An increasing number of studies are showing that Antarctic mega- and macrofauna are highly diverse, however, little is known about meiofaunal biodiversity in sediment communities, which are a vital part of a healthy and functional ecosystem. This is the first study to analyse community DNA (targeting meiofauna) using metabarcoding to investigate biodiversity levels in sediment communities of the Antarctic Penin...
Acidification effects on biofouling communities: winners and losers
Peck, Lloyd S.; Clark, Melody S.; Power, Deborah; Reis, Joao; Batista, Frederico; Harper, Elizabeth M.How ocean acidification affects marine life is a major concern for science and society. However, its impacts on encrusting biofouling communities, that are both the initial colonizers of hard substrata and of great economic importance, are almost unknown. We showed that community composition changed significantly, from 92% spirorbids, 3% ascidians and 4% sponges initially to 47% spirorbids, 23% ascidians and 29...
Polar marine biology science in Portugal and Spain: Recent advances and future ...
Xavier, José C.; Barbosa, Andrés; Agustí, Susana; Alonso-Sáez, Laura; Alvito, Pedro; Ameneiro, Julia; Ávila, Conxita; Baeta, Alexandra; Canário, JoãoPolar marine ecosystems have global ecological and economic importance because of their unique biodiversity and their major role in climate processes and commercial fisheries, among others. Portugal and Spain have been highly active in a wide range of disciplines in marine biology of the Antarctic and the Arctic. The main aim of this paper is to provide a synopsis of some of the results and initiatives undertak...
