متن کاملRevision of some ophiuroid records (Echinodermata: Ophiuroidea) from Argentina.

The species name "Ophiacantha ingrata Koehler, 1923" used for specimens from South Georgia is in...
متن کاملOphiuroidea (Echinodermata) from coral reefs in the Mexican Pacific.

In this regard, this work provides the first annotated checklist of brittle stars associated with coral communities and reefs in the Mexican Pacific and an illustrated key to identify the species. We also provide taxonomic descriptions, spatial and bathymetric ...
متن کاملNovas políticas de divisão de nós para a Slim-tree
This paper presents two new node split policies for the Slim-tree. When compared with the previously proposed policies they result in better distribution of elements on the tree nodes. This impacts positively on the performance of similarity queries such as nearest neighbors. The experimental results show that trees built with the proposed policies outperform those built with the above with reg...
