Conservation status of New Zealand freshwater fish, 2009
Abstract The threat status of 74 freshwater and estuarine fish present in New Zealand was determined. Fifty-one native taxa were ranked of which 67% were considered Threatened or At Risk. A singleExpand

Biogeographic Atlas of the Southern Ocean
The Southern Ocean waters to the west of the Antarctic Peninsula are warming faster than almost any other place on Earth. This area of most rapid environmental change was among others targeted by theExpand

Differentiation at a microgeographical scale within two species of ground beetle, Carabus auronitens and C. nemoralis (Coleoptera, Carabidae): a geometrical morphometric approach
New morphometric methods, the geometrical morphometrics, offer promising perspectives to appraise morphological variation among organisms and open up, to a large extent, the field of morphometricsExpand

Are homalozoans echinoderms? An answer from the extraxial-axial theory
Abstract Homalozoans include four classes of non-pentamerous Paleozoic echinoderms: Homostelea (cinctans), Ctenocystoidea (ctenoid-bearing homalozoans), Homoiostelea (solutes), and StylophoraExpand

Arrays in rays: terminal addition in echinoderms and its correlation with gene expression
Summary The echinoderms are deuterostomes that superimpose radial symmetry upon bilateral larval morphology. Consequently, they are not the first animals that come to mind when the concepts ofExpand

Radial Symmetry, the Anterior/Posterior Axis, and Echinoderm Hox Genes
The strangeness of echinoderm pentaradiality results from superposition of radial symmetry onto ancestral deuterostome bilaterality. The ExtraxialAxial Theory shows that echinoderms also have anExpand

Is the Species Flock Concept Operational? The Antarctic Shelf Case
There has been a significant body of literature on species flock definition but not so much about practical means to appraise them. We here apply the five criteria of Eastman and McCune for detectingExpand

What a New Model of Skeletal Homologies Tells Us About Asteroid Evolution1
Synopsis The Extraxial-Axial Theory (EAT) is applied to the body wall homologies of asteroids. Attempts to characterize major plate systems of asteroids as axial or extraxial, particularly those thatExpand
