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.

An investigation into the diet of elephant fish (Callorhinchus milii) in the waters of Aotearoa/New Zealand

Journal of Fish Biology, EarlyView.
Abstract Chondrichthyans (sharks, rays and chimaeras) are increasingly understood to be an important part of ocean ecosystems, but their ecological role is unclear. Callorhinchus milii (elephant fish) is a chimaera species endemic to Aotearoa/New Zealand and southern Australian waters.

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

Diagenetic controls on porosity evolution and pore type organisation in microporous carbonate rocks: Evidence for mesogenetic porosity formation

Sedimentology, EarlyView.
ABSTRACT Microporous carbonate rocks typically record complex diagenetic histories driven by microbial activity and fluid interactions within multiple diagenetic environments. The relative roles of meteoric and burial diagenetic processes in pore evolution remain debated, particularly within Cretaceous carbonate systems of the Middle East, as does the ...

Echinoderm ichnology: bioturbation, bioerosion and related processes [PDF]

, 2017
Among invertebrates and both in modern and ancient marine environments, certain echinoderms have been and are some of the most active and widespread bioturbators and bioeroders. Bioturbation and/or bioerosion of regular and irregular echinoids, starfish,
