ctenocidaris.nutrix: Presence-only records of the echinoid _Ctenocidaris nutrix_...

In SDMPlay: Species Distribution Modelling Playground

Description

Dataset that contains the presence of the echinoid species Ctenocidaris nutrix reported from several campaigns including RV Marion Dufresne MD03 1974 & MD04 1975, POKER 2 (2010) and PROTEKER 2013, 2014, 2015.
Ctenocidaris nutrix (Thomson 1876) is a broad range species, distributed from -70.5W to 143.7E and -76.13 to -47.18S in the Southern Ocean. The species is mainly found around the Kerguelen Plateau, and near Weddell Sea and Scotia Ridge regions. The species is known from littoral waters down to 800m. It is a carnivorous and direct developer species that breeds its youngs (David et al. 2005). Ctenocidaris nutrix is considered as an indicator species of Vulnerable Marine Ecosystems (VME) by the CCAMLR.
