the highest aggregating intensity appeared at the quadrat of 50 m~2 in the middle-aged populations and at the quadrat of 300 m~2 in the old-age populations. (4) The spatial distribution of the populations closely related to their biological and ecological characteristics and habitat conditions.
Adopting comprehensively the knowledge and theory of population ecology and disease epidemics, by the field investigations and indoor trials, the bio-ecological characteristics and the pathogenicity of C. bipunctella, the seasonal dynamic of maize wallaby ear virus (MWEV) during the period of maize growth were studied systematically.
The bio-ecological characters, species diversity of its communities, population size-classes structure, distributional pattern and genetic diversity of populations were studied, which are the scientific basis for the efficient conservation of Thuja sutchuenensis.
Ploidy of neurons was assessed by the method of nuclear DNA cytophotometry in ganglia of the central nervous system (CNS) in 28 species of Bivalvia belonging to 5 existing subclasses and having various bio-ecological characteristics.
As a consequence, communities developed under same environmental conditions should present the same combination of species bio-ecological characteristics.
Numerical simulations are carried out to test the feasibility and to study the general characteristics of the technique without the real measurement data.
Electrochemical Hydrogenation of Substituted α-Phenylvinylphosphonic Acids: General Characteristics of the Reaction Layer and Pr
A general characteristics is given to the kinetics of electroreduction of cerium-decatugstate anions on mercury, polycrystalline gold, and the pyrolytic-graphite basis plane in acetate buffer solutions (pH 3.5-6.0).
Some general characteristics of arbitrary spin structures predicted by macroscopic theory are examined, including energy associated with inhomogeneity, anisotropy, and energy in external fields.
An analysis of general characteristics of light-induced forces is presented for arbitrary monochromatic masks in which optical pumping of atoms and spontaneous emission play an important role.
