This quantity is a reprint of a vintage ebook approximately Nautilus, first released in 1987, with an introductory bankruptcy summarizing all the paintings on Nautilus and its habitat because the ebook of the 1st variation greater than twenty years in the past. The surge in articles within the final 20 years exhibits an elevated curiosity within the topic, reflecting a renewed appreciation of the complexity and fragility of the marine habitat and its biota. The 37 chapters are written via forty eight specialists within the box and canopy all points of this residing fossil from its ecology to its embryology. This quantity additionally good points new pictures, together with a magnificent photo of the 1st hatched Nautilus in captivity. Nautilus is an iconic animal within the marine realm and represents a part of the various fauna of the Indo-Pacific. it's also a member of a lineage of shelled cephalopods relationship again greater than four hundred million years. therefore, this quantity can be appropriate to the fields of marine technological know-how, evolutionary biology, and paleontology.

Molecular Biology of Long Non-coding RNAs

​Long non-coding RNAs (lnc)RNAs have emerged as a brand new paradigm in epigenetic rules of the genome. hundreds of thousands of lncRNAs were pointed out and saw in quite a lot of organisms. not like mRNA, lncRNA don't have any protein-coding skill. ​So, whereas their functionality isn't totally transparent, they might function key organizers of protein complexes that permit for larger order regulatory occasions.

The range of antigen-binding constructions of antibody molecules is so sizeable that each feasible antigen should be certain via an antibody molecule in the immune process. this can be real even for the antigen binding websites of antibodies referred to as idiotypes, that are certain by means of complementary bind­ ing websites of alternative antibodies known as anti-idiotypes.

142] Von Boletzky (1988) described cephalopod embryogenesis, emphasizing that the embryonic development of cephalopods is characterized by meroblastic cleavage in contrast to other molluscs, which typically exhibit spiralian cleavage. All cephalopod eggs are very yolky and the largest eggs (2-3 cm in length) occur in Nautilus. [67] Landman et al. (1989) described embryonic shells of N. belauensis ranging from a pre-chamber cap-like shell to a three-chambered shell. The cicatrix is the site of initial shell formation.

On the other hand, enforcement efforts would be extremely challenging in the remote areas that comprise the animals’ range, and any publicity of this new status might indirectly accelerate its overexploitation as a “natural resource,” somewhat along the lines of the elephant/ivory dilemma. Two new color figures are included: One shows the first in situ record of living Allonautilus along with Nautilus in its natural habitat (Plate III); another shows the object of Willey’s long but fruitless search, a postembryonic Nautilus, hatched at the Waikiki Aquarium in 1990 (Plate IV).

106] Ruth et al. (1999) investigated the midgut glands of N. pompilius and N. macromphalus using light and scanning electron microscopy. The gland shows a significant blood supply, a variety of different enzymatic activities, and tubular organization. Although the primary role of the midgut gland is for digestion, they also found some evidence for excretory processes. 14 [169] Westermann et al. (2000) used C-labelled food to trace absorption of food in N. pompilius. The midgut gland is most active in food absorption, followed by the caecum and crop.
