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
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
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 ...

THE ABSORPTION SPECTRA OF SOME BLOODS AND SOLUTIONS CONTAINING HEMOCYANIN
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.

Cryo-EM reveals the asymmetric assembly of squid hemocyanin
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.
