Mycological composition of soils in Kuban rice agrocenoses as a biotic component for their health [PDF]
Studies of the water-physical, physical-chemical and biological properties of meadow-chernozem soils were carried out on a rice irrigation system located in the present-day delta of the Kuban River. Rice meadow-chernozem soils have good water and general

Relative importance of biotic and abiotic soil components to plant growth and insect herbivore population dynamics. [PDF]
Plants are affected by several aspects of the soil, which have the potential to exert cascading effects on the performance of herbivorous insects. The effects of biotic and abiotic soil characteristics have however mostly been investigated in isolation ...

THE DOSE-EFFECT OF OIL POLLUTION OF SOILS ON THE BIOTIC COMPONENT OF ECOSYSTEMS
The degree of influence on the biotic component of ecosystems depends on the level of oil contamination present in the soil. To determine the dose-effect, the reaction of living objects of different levels of organization with the use of methods of ...

All kinds of micro- and macroorganisms live in the massifs of clay soils: plants living in (or on) clay soils are called pelitophytes (from the Greek πηλός - “clay” and phyton - “plant”), micro- and macroorganisms living in clays, or associated with clays, they are called pelitophiles (from the Greek πηλός - "clay" and φιλία - "love"), that is, "loving

The apoplastic oxidative burst in response to biotic stress in plants: a three-component system [PDF]
The oxidative burst, the generation of reactive oxygen species (ROS) in response to microbial pathogen attack, is a ubiquitous early part of the resistance mechanisms of plant cells. It has also become apparent from the study of a number of plant-pathogen interactions and those modelled by elicitor treatment of cultured cells that there may be more ...

Abscisic Acid-Induced Stomatal Closure: An Important Component of Plant Defense Against Abiotic and Biotic Stress [PDF]
Abscisic acid (ABA) is a stress hormone that accumulates under different abiotic and biotic stresses. A typical effect of ABA on leaves is to reduce transpirational water loss by closing stomata and parallelly defend against microbes by restricting their

Effects of herbicide treatments on biotic components in regenerating northern forests [PDF]
We reviewed literature, primarily since 1990, that documents effects of herbicide treatments on major biotic components in northern forested ecosystems. Vegetation changes are responsible for changes in all other biotic components. Non-conifer vegetation is commonly reduced for two to five years following broadcast herbicide treatments.

Analytical review of modern studies of changes in the biotic components of the carbon cycle
The research on changes in the spatial-temporal dynamics of carbon in natural ecosystems on land is explored. The works of Russian and foreign authors on the analysis of the depositing ability of the cover are presented. Works on biomass reserves and primary production of biogeocenoses, research in the field of mathematical modeling of the carbon cycle

Temporal Effects of Groundwater on Physical and Biotic Components of a Karst Stream [PDF]
Although most lotic ecosystems are groundwater dependent, our knowledge on the relatively long-term ecological effects of groundwater discharge on downstream reaches remains limited. We surveyed four connected reaches of a Chinese karst stream network for 72 consecutive months, with one reach, named Hong Shi Zi (HSZ), evidently affected by groundwater.
