1 – Dynamics of the Integument

TL;DR: This review provides an overview of recent laboratory studies of cues that shorten or lengthen the time to metamorphosis (TTM) of the megalopa stage of brachyuran crabs and finds no evidence that structural mimics of natural substrate affect TTM.

TL;DR: A pathogenic virus was diagnosed from juvenile Caribbean spiny lobsters Panulirus argus from the Florida Keys, apparently widespread, infectious, and lethal to the CaribbeanSpiny lobster.

TL;DR: High specific Ca content seems to be a common property of Daphnia spp.

TL;DR: The mechanism and kinetics of Ca-containing biomineral dissolution is analyzed within the framework of (i) diffusion-re reaction theory; (ii) surface-reaction controlled, morphology-based theories, and (iii) phenomenological surface coordination models.

TL;DR: Homogenized exuviae of the crayfish Orconectes sanborni were extracted in a series of solutions capable of dissolving protein molecules held together by forces weaker than covalent cross-links, and only half the total protein present was removed.

TL;DR: A model for the endocuticle based on a helicoidal configuration of microfibrillar laminae is proposed and the vertically striated structures seen in sections of the outer layer are accounted for by including regular rows of particles oriented perpendicular tomicrofibrils.

TL;DR: Young specimens of Elminius modestus Darwin, were marked by treatment with calcium and strontium-enriched sea water, allowed to grow in the intertidal environment, and marked again, and the number of growth bands laid down coincided with thenumber of tidal immersions.

TL;DR: The cells are believed to synthesize lipo-protein or extract it from the haemolymph, and to transport it to the epidermis and thence to the developing cuticle, thus contributing to the secretion of the epicuticle and impregnating the pre-exuvial endocuticle.
