brisaster.antarcticus: Presence-only records of the echinoid _Brisaster antarcticus_...

In SDMPlay: Species Distribution Modelling Playground

Description

Dataset that contains the presence records of the echinoid species Brisaster antarcticus reported from several oceanographic campaigns including RV Marion Dufresne MD03 1974 & MD04 1975, POKER 2 (2010) and PROTEKER 2013, 2014, 2015.
Brisaster antarcticus (Doderlein 1906) is distributed from 3.5 to 75.6W and -53.35 to -45.95S in the Southern Ocean. The species is mainly found around Kerguelen and Crozet Islands. Brisaster antarcticus commonly lives from 100 to 600 meters depth. It is a detrivorous species for which reproduction includes dispersal (David et al. 2005).

See Guillaumot et al. (2016) for more details.
