1 – Dynamics of the Integument

TL;DR: The data suggest that levels of 18:2n-6 and 18:3n-3 are regulated, and that 20:4n- 6 can be synthesised from 18:1n-9 and 20:5n-4, while that of 20:6-3 and 22:6n- 3 are controlled by starvation, and there is no clear evidence that 20-5-3-2 and 22-6-4 are essential in P. esculentus.

TL;DR: In this paper, seasonal changes in the levels of Ca, Sr, Ba, Mn, Fe, Al, Mg, Zn and Cd in the net plankton (> 250 μm) of three Canadian Shield lakes are described, and major temporal, multielemental patterns are extracted using non-metric multidimensional scaling.

TL;DR: The behavioral evidence suggests that males are responding to an insoluble substance in or on the exoskeleton of the postmolt parturial female, which might be a contact sex pheromone in P. pugio and other carideans.

TL;DR: The prawn selected for the present study is widely used in the shrimp culture fields of tropical regions along with Pen- aeus monodon and information on such physiological characteristics of the candidate species is important for the management of the ecosystem in which prawns are cultured, understanding of nutritional needs and pathological conditions of the prawn.

TL;DR: The structure of α-chitin has been determined by X-ray diffraction, based on the intensity data from deproteinized lobster tendon Least-squares refinement shows that adjacent chains have alternating sense (i are antiparallel) In addition, there is a statistical distribution of side-chain orientations, such that all the hydroxyl groups form hydrogen bonds as discussed by the authors.

TL;DR: It is shown that resilin is a structure protein in which the primary chains show little or no tendency to form secondary structures; they are bound together in a uniform three-dimensional network (the tertiary structure) with no potential limits as to size.
