A first nuclear and mitochondrial genomic portrait of Robinson Crusoe's (Juan Fernandez Island) spiny lobster Jasus frontalis (Crustacea: Decapoda: Achelata).

ABSTRACT:

Background

The Juan Fernández rock lobster Jasus frontalis (H. Milne-Edwards, 1837) is found along the Juan Fernández archipelago and Desventuradas Islands in the southeastern Pacific Ocean where it supports a profitable but likely unsustainable artisanal fishery. Only a few genomic resources are available for this species to support efficient managing practices. In this study, we took a first look at the genome of J. frontalis profiting from recently developed bioinformatics tools that mine for biological insight from low sequencing-depth datasets. Specifically, we have (i) estimated the nuclear genome size, (ii) assembled and described in detail the mitochondrial genome, (iii) discovered, quantified, and annotated nuclear transposable elements, and (iv) examined the phylogenetic
