Zonation is one of the most obvious features of a rocky shore and, with a little effort, it can also be recognized on sandy beaches and mudflats. Each species has an upper and lower distributional limit along the vertical intertidal gradient, and the factors which set those limits have long attracted the attention of shore ecologists, particularly for ...

There is ample evidence that a progressive change in the intensity of an important environmental factor leads to the formation of zones or belt-like communities in which the plant species reflect a fairly distinct range of tolerance for that factor (Daubenmire 1968).

Chemoarchitectonic zonation of the monkey cerebellum
Brain Research, 1986The modular organization of the monkey cerebellum is revealed in normal material by histochemical methods for demonstrating the presence of the enzymes acetylcholinesterase (AChE) and cytochrome oxidase (CO). In the cerebellar white matter, AChE- and CO-rich fibers are distributed in longitudinal compartments, which are aligned with AChE- and CO-rich ...

A Survey on Risk Zonation of Lightning
2020This paper not only reviews a series of studies on disaster risk zoning in the field of lightning disaster prevention in the past decade, but also combs and evaluates the results and methods of this research direction. It aims to summarize the work of lightning disaster risk zoning in recent years.

Dynamic zonation of liver polyploidy
Cell and Tissue Research, 2016The liver is a polyploid organ, consisting of hepatocytes with one or two nuclei each containing 2, 4, 8 or more haploid chromosome sets. The dynamic changes in the spatial distributions of polyploid classes across the liver lobule, its repeating anatomical unit, have not been characterized.

Metabolic Zonation of Liver Parenchyma
Seminars in Liver Disease, 1988Periportal and perivenous hepatocytes differ in their content of enzymes and subcellular structures and thus in their metabolic capacities. Therefore, the model of metabolic zonation proposes that: (1) periportal hepatocytes catalyze predominantly oxidative energy metabolism with beta-oxidation and amino acid catabolism as well as ureagenesis for ...
