Phylogeny of Echinoderm Hemoglobins

BACKGROUND Recent genomic information has revealed that neuroglobin and cytoglobin are the two principal lineages of vertebrate hemoglobins, with the latter encompassing the familiar myoglobin and α-globin/β-globin tetramer hemoglobin, and several minor groups. In contrast, very little is known about hemoglobins in echinoderms, a phylum of exclusively marine organisms closely related to vertebr...

The echinoderm adhesome.

Although the development of sea urchin embryos has been studied extensively and clearly involves both cell adhesion and cell migration, rather little is known about the adhesion receptors and extracellular matrix molecules involved. The completion of the genome of Strongylocentrotus purpuratus allows a comprehensive survey of the complement of cell-cell and cell-matrix adhesion molecules in thi...

Late Eocene siliceous sponge fauna of southern Australia: reconstruction based on loose spicules record.

An abundant and diversified assemblage of siliceous loose sponge spicules has been identified in the Late Eocene deposits cropping out along the southern coasts of Australia. Based on the comparison of the obtained spicules with those of living sponges, representatives of at least 43 species within 33 genera, 26 families, and 9 orders of "soft" Demospongiae and Homoscleromorpha have been identi...

The significance of the subterranean fauna in biogeographical reconstruction: examples from Cape Range peninsula, Western Australia

Cape Range peninsula contains a diverse troglobite (obligatory cave inhabitants) fauna, the only rich troglobite community known in Western Australia and in the semi-arid tropics. At least thirtyeight species of troglobite (or stygobiont) in this sparsely sampled area place it amongst the worlds faunistically diverse karst areas. The characteristics of the region and its subterranean fauna are ...
