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

open access: yesMarine 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.

Low‐Concentration Enhancement Effect: Enabling Sensitive Detection of EML4‐ALK Variants via Multiplex RT‐MIRA

open access: yesJournal of Clinical Laboratory Analysis, EarlyView.
This study developed an optimized multiplex RT‐MIRA assay for the simultaneous detection of EML4‐ALK variants, achieving single‐copy sensitivity. Unexpectedly, during the development of the reaction system, we discovered a “low‐concentration enhancement effect,” where reducing primer or probe concentrations within a specific range markedly improved ...

Calpain Proteases and the Evolving Signaling Network in Insect Embryonic Patterning

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Insect embryonic Dorsal‐Ventral (DV) patterning relies on the BMP and Toll pathways to different extents. Calcium‐dependent cystein proteases of the Calpain family also exert an important function to pattern the DV axis. In Drosophila, Calpain A cleaves the Cactus/IkappaB inhibitor and modifies Toll signals in ventral regions of the embryo. In Rhodnius

Is DNA metabarcoding an option for formaldehyde‐preserved zooplankton time series?

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract The recovery of amplifiable DNA from formaldehyde‐fixed (FF) zooplankton samples has long been considered problematic, but advances in degraded‐DNA retrieval have renewed interest in FF samples. To access the information stored in long‐term zooplankton time series, we evaluated methods for extracting amplifiable DNA from community samples ...

Crinoid phylogeny: a preliminary analysis (Echinodermata: Crinoidea) [PDF]

open access: yes, 2004
We describe the first molecular and morphological analysis of extant crinoid high-level inter-relationships. Nuclear and mitochondrial gene sequences and a cladistically coded matrix of 30 morphological characters are presented, and analysed by ...

Direct, but not indirect, predation‐risk cues deter larval settlement in a scyphozoan jellyfish

open access: yesJournal of Animal Ecology, EarlyView.
Predators can shape population dynamics before consumption occurs, with prey using chemical information to guide larval settlement. We show that jellyfish larvae (Aurelia coerulea) respond selectively to predation‐risk cues, reducing settlement in response to predator presence and active predation cues, but not to residual cues from previously preyed ...

Morphological and Morphometric Characterisation of Selected Camarodont Sea Urchin (Echinoidea: Camarodonta) Pedicellariae (Paracentrotus lividus, Psammechinus miliaris and Echinus esculentus)

open access: yesActa Zoologica, EarlyView.
ABSTRACT Pedicellariae are small appendages on the surface of the echinoid test, involved in defence, cleaning, and locomotion. Pedicellariae in three species of camarodont sea urchins common in UK waters (Paracentrotus lividus [Lamarck, 1816], Psammechinus miliaris [P.L.S Müller, 1771] and Echinus esculentus [Linnaeus, 1758]) are the focus of this ...
