Marine heat wave and multiple stressors tip bull kelp forest to sea urchin barrens

open access: yesScientific Reports, 2019
Extreme climatic events have recently impacted marine ecosystems around the world, including foundation species such as corals and kelps. Here, we describe the rapid climate-driven catastrophic shift in 2014 from a previously robust kelp forest to ...

Gonad quality of sea urchin Tripneustis gratilla with different seaweed diets

open access: yesJurnal Akuakultur Indonesia, 2020
Gonad quality of sea urchin Tripneustis gratilla is influenced by consumed seaweed type. Therefore, this study was conducted to determine the type of seaweed as potential source of carotenoids and produce a good quality of sea urchin gonad. The study was

A variant mimicking hyperphosphorylated 4E-BP inhibits protein synthesis in a sea urchin cell-free, cap-dependent translation system. [PDF]

open access: yesPLoS ONE, 2009
BACKGROUND: 4E-BP is a translational inhibitor that binds to eIF4E to repress cap-dependent translation initiation. This critical protein:protein interaction is regulated by the phosphorylation of 4E-BP.

Sea urchin utilisation in Eastern Indonesia

open access: yesIlmu Kelautan, 2023
Sea urchins have long been an important component of gleaning invertebrate fisheries and are valued for their highly nutritious gonads. Sea urchin fisheries are often unreported and unregulated, despite increasing indications of overexploitation. Data on

Bioerosive impact of Diadema mexicanum on southern Mexican Pacific coral reefs

open access: yesCiencias Marinas, 2016
Reef ecosystem growth and maintenance is closely related to sea urchin feeding activities. Hence, quantifying the bioerosive capacity of the sea urchin Diadema mexicanum is necessary to evaluate its impact on coral communities and reefs that develop off

Dypeptydylpeptidase IV Activity Ingibition after Oral Administration to Rabbits of Strongylocentrotus Droebahiensis Gonads Extract as Possible Biomarker of Pharmakokinetics

open access: yesРазработка и регистрация лекарственных средств, 2020
Introduction. The pharmacokinetic profiling of active compounds is necessary for drug development and application. Comlex extract of biologically active compounds was isolated from gonads of green sea urchin Strongylocentrotus droebachiensis from Barents

Eutacticity in Sea Urchin Evolution [PDF]

open access: yesBulletin of Mathematical Biology, 2007
An eutactic star, in a n-dimensional space, is a set of N vectors which can be viewed as the projection of N orthogonal vectors in a N-dimensional space. By adequately associating a star of vectors to a particular sea urchin we propose that a measure of the eutacticity of the star constitutes a measure of the regularity of the sea urchin. Then we study

RNA-Seq identifies SPGs as a ventral skeletal patterning cue in sea urchins [PDF]

open access: yes, 2016
The sea urchin larval skeleton offers a simple model for formation of developmental patterns. The calcium carbonate skeleton is secreted by primary mesenchyme cells (PMCs) in response to largely unknown patterning cues expressed by the ectoderm.
