ResumenOne of the main goals of natural history collections is to preserve for a long term the specimens used for describing and naming new species for science. In this sense, the Biological Reference Collections (CBR) at the Institut de Ciències del Mar of the Consejo Superior de Investigaciones Científicas are a key site for the study and research on marine biodiversity since they act as a scientific marine reference facility. The concept of natural history collections is not dead. On the contrary, biological collections are dynamic and continuously incorporate species new to science, as well as relevant specimens related with the temporal dynamics in marine biogeography. Also, we are far from knowing all life stages of species, and in this way, the knowledge of larval and yet undescribed stages is relevant for solid and precise field and laboratory species identification. Genetic analyses are widely used and voucher specimens need to be deposited in biological collections. As an example, the recent dynamics in the decapod crustacean collection are presented. Presently, a total of 35 species types are present in our collection, of which 13 are holotypes. In the past two years two new holotypes, namely Uroptychus cartesi Baba & Macpherson, 2012 and Munidopsis ariadne Macpherson, 2011, as well as other types, have been deposited in our collections. Overall the CBR gather presently a total of 467 different decapod crustacean species, mainly from Mediterranean and adjacent Atlantic waters, but also from the Southeast Atlantic and other marine areas where the Institut de Ciències del Mar has performed research projects. We will present how new research topics influence the growth of this collection. If we look at the new arrivals, several patterns arise: species new to science, larval and juvenile stages (life history), DNA vouchers for phylogenetic or population biology studies, species expanding their range naturally or in a human induced way (invasive alien species, biogeographical dynamics, global change,...) and rare or poorly known species. So, new specimens and holotypes have arrived for scientific and reference use!
