Investigating stock structure in Sardinops sagax in the southern Benguela region using microsatellites.

submitted by: Shannon_Hampton
Small pelagic fish are characterised by large population size and an extended larval duration. They are found over wide geographical distances with limited barriers to gene flow. It is thus important to investigate the extent of limited genetic differentiation in such populations. Several studies have explored genetic structuring in small pelagic species around the world. The level of genetic structuring in southern Benguela sardine ( Sardinops sagax) is currently under investigation,...

Phylogeny of glass sponges (Hexactinellida: Hexasterophora): An analysis based on morphological characters

submitted by: Dorte_Janussen
The Porifera class Hexactinellida is a classical deep-sea sponge taxon, with few exceptions (e. g. Rossellidae of the Antarctic shelf) occurring below 1000 m. In a joint project with WG of Gert Wörheide (Munich Univ.) (DFG: JA1063/13,1-3, WO896/5,1-4), we investigate the phylogenetic relationships of this (maybe oldest) animal old taxon; promising for understanding of Early Metazoan evolution. Since the Cenozoic hexactinellid sponges are almost exclusively restricted to deep water...

Protecting what we know: the need for mapping of soft-coral habitats for MPA design in Malta

submitted by: Alan_Deidun

Paramuricea clavata is considered as one of the main representative species of gorgonian soft corals in view of its attractive shape, impressive size and density, and is used in many studies to illustrate the importance of plankton-benthos coupling. P. clavata is typically reported from sciaphilic, near-horizontal rocky walls and its presence was never previously recorded from Maltese coastal waters. It is not even designated in local environmental legislation as a protected species.
