Length–Weight Relationships of Commercial Species in the Eastern Australian Sea Cucumber Fishery

Diversity
Biological data, such as length–weight relationships, are essential for the management and stewardship of harvested individuals. Sea cucumbers are a lucrative industry globally but many of the associated fisheries lack species-level biological data ...

Molecular approach to echinoderm regeneration

, 2001
Until very recently echinoderm regeneration research and indeed echinoderm research in general has suffered because of the lack of critical mass. In terms of molecular studies of regeneration, echinoderms in particular have lagged behind other groups in ...

Molecular paleobiology of the echinoderm skeleton

Molecular paleobiology provides a promising avenue to merge data from deep time, molecular biology and genomics, gaining insights into the evolutionary process at multiple levels. The echinoderm skeleton is a model for molecular paleobioloogical studies.

Structural Features and Phylogenetic Implications of Crinoid Echinoderms Based on Thirteen Novel Mitochondrial Genomes

Journal of Marine Science and Engineering
Crinoids, as integral echinoderms, play a crucial ecological role in benthic communities, serving as significant indicators reflecting the health of marine ecosystems. However, the phylogenetic relationships within crinoids are unclear.

Electron microprobe study of magnesium distribution in some Mississippian echinoderm limestones from western Canada

, 1970
Electron microprobe techniques were used to examine the distribution of Mg, Ca, and Fe in six samples of Mississippian skeletal and oölitic limestones from the Alberta Rocky Mountains. All samples show extremely low values of Fe.

Length–Weight and Body Condition Relationships of the Exploited Sea Cucumber Pearsonothuria graeffei

Journal of Marine Science and Engineering
Fishery stock assessments are often based on morphometric data from underwater diver surveys and landing surveys. Measurements of body length are usually converted to estimates of body weight, yet length–weight equations might differ among localities. We

Assembling the Echinoderm Tree of Life: Challenges and Plans

, 2010
A multidisciplinary team of biologists have recently assembled to study echinoderm phylogeny. The team has an award from the National Science Foundation Program, Assembling the Tree of Life.

Deep-sea echinoderm oxygen consumption rates and an interclass comparison of metabolic rates in Asteroidea, Crinoidea, Echinoidea, Holothuroidea and Ophiuroidea

, 2011
Echinoderms are important components of deep-sea communities because their abundance and their activities contribute to carbon cycling. Estimating echinoderm contribution to food webs and carbon cycling is important to our understanding of the ...

Imaging of Echinoderm Fertilization

Molecular Biology of the Cell, 1998
Eggs from echinoderms (sea urchin, starfish, and sand dollars) have been an excellent subject for cell biology for more than 100 years. Among the many discoveries that have been made with echinoderm eggs are the first studies of the centrosome (Boveri, 1902 ; also see Baltzer, 1967 ), the Ca requirement for healing plasma membrane wounds (Chambers ...
