Impact of noise on the behaviour and biochemical parameters of the crayfish Cherax quadricarinatus and Cherax destructor

open access: yesJournal of Zoology, Volume 328, Issue 2, Page 146-164, February 2026.
The aim of this study was to evaluate the effect of acoustic stimulus on the behavioural and biochemical responses of two species of crayfish, Cherax destructor and Cherax quadricarinatus. Our results showed that exposure to noise significantly affects in both species motility parameters, agonistic interactions and acoustic signals emitted. In terms of

Copper Complexes with Guanidine‐Based Tripodal Ligands and their Reactivity Toward Dioxygen

open access: yesZeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 1, January 6, 2026.
Results on the stabilization of end‐on superoxido copper complexes by applying ligands with guanidine groups. The copper(I) TMG3tren complex (TMG3tren = a tris(2‐aminoethyl)amine ligand modified with guanidine groups) reacts with dioxygen exclusively to form a relatively stable end‐on superoxido complex. In contrast, the related copper(I) tmpa complex (

THE TRANSPORT OF OXYGEN AND CARBON DIOXIDE BY SOME BLOODS CONTAINING HEMOCYANIN

open access: yes, 1926
Since the classic observations of Bert (1867) and Fredericq (1878) called attention to the significance of the copper-protein compound, hemocyanin, subsequent investigators have concerned themselves with two questions of biological importance.’ What is ...

Biomolecular changes that occur in the antennal gland of the giant freshwater prawn (Machrobrachium rosenbergii).

open access: yesPLoS ONE, 2017
In decapod crustaceans, the antennal gland (AnG) is a major primary source of externally secreted biomolecules, and some may act as pheromones that play a major role in aquatic animal communication.

Gene and expression analysis of the hexamerin family proteins from the grasshopper, Locusta migratoria (Orthoptera: Acridoidea)

open access: yesBiotechnology & Biotechnological Equipment, 2017
Hexamerins are large hemolymph-proteins that have been discovered in all insect species. According to the present study, hexamerins are not only storage proteins that provide amino acids and energy, but also transport hormones such as ecdysteroids.

Color morphology of Diaphorina citri influences interactions with its bacterial endosymbionts and 'Candidatus Liberibacter asiaticus'.

open access: yesPLoS ONE, 2019
Diaphorina citri is a vector of 'Candidatus Liberibacter asiaticus,' (CLas), associated with Huanglongbing, (HLB, or citrus greening) disease in citrus. D. citri exhibits three different color morph variants, blue, gray and yellow.

THE ABSORPTION SPECTRA OF SOME BLOODS AND SOLUTIONS CONTAINING HEMOCYANIN

open access: yes, 1930
1. The absorption of light by the blood and by purified preparations of the hemocyanin of the conch, Busycon canaliculatum, the horse-shoe crab, Limulus polyphemus, the squid, Loligo pealei, and the lobster, Homarus americanus, has been studied.

Molecular Cloning, Characterization, and mRNA Expression of Hemocyanin Subunit in Oriental River Prawn Macrobrachium nipponense

open access: yesInternational Journal of Genomics, 2016
Hemocyanin is a copper-containing protein with immune function against disease. In this study, a hemocyanin subunit named MnHc-1 was cloned from Macrobrachium nipponense. The full-length cDNA of MnHc-1 was 2,163 bp with a 2,028-bp open reading frame (ORF)

Cryo-EM reveals the asymmetric assembly of squid hemocyanin

open access: yesIUCrJ, 2019
The oxygen transporter of molluscs, hemocyanin, consists of long pearl-necklace-like subunits of several globular domains. The subunits assemble in a complex manner to form cylindrical decamers.
