Wood Anatomy of Cneoraceae: Ecology, Relationships, and Generic Definition
Wood anatomy of the three species of Cneorurn is described qualitatively and quantitatively. The species differ in features related to ecology and form a clear series in this regard. The wood features of the family can all be matched by some Rutaceae and Simarubaceae, and the characteristics of Cneoraceae are listed in this connection. Nearly as many features are shared by Cneoraceae with Anaca...
متن کاملFractal Population Ecology Theory
Abstract Purpose - The aim of this paper is to describe the population ecology theory through fractal thinking, an emergent human operating system that is creative, adaptive, healthy, and evolutionary; furthermore, a parallel is drawn between the population ecology model and the fractal structure. Top-down hierarchies are typically characterized by command and control systems of the authority t...
متن کاملHypercomputation by definition
Hypercomputation refers to computation surpassing the Turing model, not just exceeding the von Neumann architecture. Algebraic constructions yield a $nitely based pseudorecursive equational theory (Internat. J. Algebra Comput. 6 (1996) 457–510). It is not recursive, although for each given number n, its equations in n variables form a recursive set. Hypercomputation is therefore required for an...
متن کاملDefinition by means of indefiniteness.
Humans recognize themselves as a part of humanity, of the biological world and of life simultaneously. They identify themselves differently in each case. However, in the absence of an accurate definition of life, the process of the identification of humanity remains incomplete. The incompleteness of this process justifies the numerous attempts to define life. Nevertheless, none of these previou...
متن کاملDefinition of sampling units begets conclusions in ecology: the case of habitats for plant communities
In ecology, expert knowledge on habitat characteristics is often used to define sampling units such as study sites. Ecologists are especially prone to such approaches when prior sampling frames are not accessible. Here we ask to what extent can different approaches to the definition of sampling units influence the conclusions that are drawn from an ecological study? We do this by comparing a fo...
