Inbriding as the regulation factor of pathogenesis in forest ecosystems Imbreeding, as the reproduction from the mating  of  genetically related parents, is usual in the wild nature. As purposeful process, inbreeding is widely applied in selection of plants and animals. Inbreeding results in increased homozygosity. Homozygosity  can increase the chances of offspring being affected by recessive or deleterious traits. The homozygosity of  offspring    usually raises, because the number of identical alleles in their genomes of the subsequent individuals  increases. Homozygosity reduces fitness of population, weakens it, that is causes inbreeding depression. The purpose of the given work –    to use the factor of the inbreeding depressions for suppression of pathogenic  populations in forest ecosystems. Inbreeding in the ecosystems is reached as a result of reproductive isolation of pathogenic organisms. Inbreeding leads to a decreased fitness of a population. The researches were spent in the Central Russian forest-steppe. Modelling test objects were the economically significant  and well-known fungi   Erisiphe alphitoiges, Heterobasidion annosum and Porodaedalea pini.

Behavioral effects of female sex hormones of different nature of the immobilized male white rats Frolova Galina Aleksandrovna, Bogdanova Svetlana Aleksandrovna Found that the sensitivity of male white rats to immobilization stress (10 days of 2 hours) is directly dependent on baseline activity of the animals. Natural female sex steroid estrone (estrone, 1.0 mg/kg, 10 days) caused an inhibition of locomotor and exploratory activity in stressed rats is not dependent on the initial level of activity. Synthetic analogue of the female sex hormone origin of non-steroidal (sinestrol, 0.8 mg/kg, 10 days) in low and intermediate level of stressed rats acts as a stress-limiting factor, high-level direction of impact of sinestrolom coincides with the effects of estrone.
