The Sp185/333 system of genes, messages and proteins are expressed in the coelomocytes of the purple sea urchin, Strongylocentrotus purpuratus, and is an extraordinary example of diversification of a putative innate immune response system in an invertebrate. Reviewed here, is the current understanding of this complex system as illustrated by sequence comparisons of the genes, messages and deduc...
The identification of species present in an ecosystem and the assessment a faunistic inventory is first step any ecological survey conservation effort. Thanks to technological progress, DNA barcoding has sped up great support morphological taxonomy. In this work, we used “Reverse Taxonomy” approach, where molecular (DNA barcoding) analyses were followed by (skeletal features) ones determine spe...
An echinoderm fauna from the San Salvatore Formation (Middle Triassic, Southern Alps) is here described in detail for first time. Identifiable crinoids and echinoids were collected three different localities: Mt. (Ticino, Switzerland), Rasa di Varese Michele (Lombardy, Italy). Crinoid taxa include Encrinus cf. aculeatus, Holocrinus sp. indet., Zardinicrinus granulosus, Encrinidae gen. et indet....
