Conservation Science and PracticeThe understanding of the depletion of species and communities and recovery following the reduction of pressures is fundamental in conservation biology. The impact of bottom trawl fisheries on benthic communities has been well studied, but there are few ...

Frontiers in ImmunologyIntroductionThe California purple sea urchin, Strongylocentrotus purpuratus, relies exclusively on an innate immune system to survive in its pathogen rich marine environment. Central to this defense is the SpTransformer (SpTrf) gene family that is unique

Integrative Organismal BiologySynopsis Animal phyla are distinguished by their body plans, the ways in which their bodies are organized. A distinction is made, for example, among phyla with bodies of many segments (metameric; e.g., annelids, arthropods, and chordates), others with completely unsegmented bodies (americ; e.g., flatworms and mollusks), and a few phyla ...

Zoologica Scripta, EarlyView.ABSTRACT Hadal environments (> 6000 m ocean depths) are often viewed as isolated locations with high species endemism due to limited dispersal. However, molecular studies continue to reveal greater complexity that questions historical perceptions. Recent population genetic studies focused on scavenging amphipods have identified broadly distributed ...

Contribution to the knowledge of echinoid fauna from Persian Gulf (Echinodermata: Echinoidea) [PDF]
Iranian Journal of Animal Biosystematics, 2016 Species identification is always important. Records of sea urchins and sand dollars species (Echinodermata, Echinoidea) is given from Iranian waters. Nine Species of Echinoderms were identified through the study.

Progress and Challenges in Phylogenomics and Genomics of Lophotrochozoa/Spiralia
Zoologica Scripta, EarlyView.ABSTRACT Lophotrochozoa is one of the three major bilaterian groups comprising more than half of the bilaterian phyla. Lophotrochozoa includes among others Mollusca, Annelida, Platyhelminthes and Rotifera. Despite representing such a large proportion of animal diversity, they are historically understudied and genomic resources have been scarce. However,

Developmental gene regulatory network architecture across 500 million years of echinoderm evolution [PDF]
, 2003 Evolutionary change in morphological features must depend on architectural reorganization of developmental gene regulatory networks (GRNs), just as true conservation of morphological features must imply retention of ancestral developmental GRN features ...

Inhibition and relaxation of sea urchin sperm flagella by vanadate [PDF]
, 1980 Direct measurements of the stiffness (elastic bending resistance) of demembranated sera urchin sperm flagella were made in the presence of MgATP2- and vanadate.
