PESI - a taxonomic backbone for Europe
2015
Reliable taxonomy underpins communication in all of biology, not least nature conservation and sustainable use of ecosystem resources. The flexibility of taxonomic interpretations, however, presents a serious challenge for end-users of taxonomic concepts. Users need standardised and continuously harmonised taxonomic reference systems, as well as highquality and complete taxonomic data sets, but these are generally lacking for nonspecialists. The solution is in dynamic, expertly curated web-based taxonomic tools. The Pan-European Species-directories Infrastructure (PESI) worked to solve this key issue by providing a taxonomic e-infrastructure for Europe. It strengthened the relevant social (…
Morphometric diversity of the mussel Brachidontes pharaonis in different coastal environments
2010
In the debate on how and why biodiversity evolves spatially and temporally and in an attempt to assess the further effects of anthropogenic activities, the ability of marine invertebrate to express a large spectrum of phenotypical plasticity can have a central role. The ability of a single genotype to produce more than one alternative form of morphology and/or physiological state should be larger in species living in highly changing waters like shallow habitats. Invertebrates, there, usually experience ample changes of temperature and food availability on annual, seasonal, diurnal and hourly bases which are the two main drivers leading the life histories of these organisms. In such circumst…
Special Issue "Historical and Current Diversity Patterns of Mediterranean Marine Species"
2021
The Mediterranean Sea is a semi-enclosed basin that experienced different natural and anthropogenic phenomena, which produced biological diversity changes over time. The Mediterranean Sea has been through dramatic changes in its biota over the last 6 million years, and more rapidly in the past century. All the events left a footprint on the gene pool of marine species, on their morpho-physiological traits, and on the loss or expansion of the geographical range extent. Nowadays, the Mediterranean is changing its physical and ecological features. The changes in its environmental conditions are followed by changes in species composition, of which most of the heritage has been stored and preser…
