Sea cucumbers in a pickle: the economic geography of the serial exploitation of sea cucumbers

Ecology and Society, 2019
Serial exploitation comprises a pattern of the human exploitation of wild harvest fisheries, where previously untapped species or locations come under exploitation over both space and time.

Global distribution of aquatic animal telemetry effort reveals geographic biases and opportunities for more inclusive tracking studies

Conservation Science and Practice, EarlyView.
Despite broad global distribution of aquatic telemetry studies, important biogeographic regions remain poorly investigated. The most important variables correlated with the distribution of telemetry studies were political stability, conservation funding, number of scientific documents, and English as a first language.

Characterization of dermatan sulfate and chondroitin sulfate profiles during brain regeneration in Styela plicata

The FEBS Journal, EarlyView.
Adult ascidians are capable of regenerating their entire brains following injury, and glycosaminoglycans have been shown to either promote or inhibit neuritogenesis. In this study, dermatan 2,6‐disulfate (D2,6S) was identified as the predominant complex carbohydrate in the ascidian brain.

Phanogracilins A–C, New Bibenzochromenones of Crinoid Phanogenia gracilis (Hartlaub, 1890)

Biomolecules
Three new bibenzochromenones named phanogracilins A–C (1–3) were isolated from the crinoid Phanogenia gracilis. The structure of 1 was established using X-ray crystallography as 5,5′,6,6′,8,8′-hexahydroxy-2,2′-dipropyl-4H,4′H-[7,9′-bibenzo[g]chromene]-4 ...

The state of knowledge on four families of Syngnathoidei fishes (Teleostei: Syngnathiformes): Aulostomidae, Centriscidae, Fistulariidae and Solenostomidae

Journal of Fish Biology, EarlyView.
Abstract Knowledge on the ecology and life‐history traits of coastal marine species is vital to inform their conservation and management, especially as their coastal habitats come under increasing threats. However, such data have never been collated for four of the five families in the suborder Syngnathoidei—the close relatives of the better‐studied ...

Prickly Defenders: A Review of Venomous Sea Urchins (Echinoidea)

Marine Drugs
Sea urchins, Echinoidea, are widely known for their defensive spines and pedicellariae, with some species having co-evolved venom in conjunction with those appendages. Despite this, their venomous arsenal remains poorly understood.

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.

Palaeobiogeography of Ordovician echinoderms [PDF]

, 2013
The palaeobiogeographical distribution of the six major clades of Ordovician echinoderms (asterozoans, blastozoans, cri- noids, echinozoans, edrioasteroids and stylophorans) is analysed based on a comprehensive and up-to-date database compiling 3701 ...
