Head Lobachevska Oksana V, Registration Date 18-03-2025 Organization popup.description1 The purpose of scientific investigation is to study the morphological, physiological and biochemical adaptive reactions and reproductive strategy of bryophytes, depending on the influence of natural and anthropogenic factors (lighting, water and temperature, recreational loading, cutting down, fires, etc.), to analyze their influence on the cenopopulations quantitative parameters and changes in moss communities, to evaluate the possibility of bryophytes use for indicating of the state of Ukrainian Roztoche forest ecosystems. popup.description2  Bryophytes and their communities of protected ancient and anthropogenically disturbed forest ecosystems of the Ukrainian Roztochchya region and a complex of ecological and morpho-physiological indicators depending on the intensity of lighting, water and temperature regime of the locality were studied. It was established that epigean bryophytes respond to changes in forest environmental conditions by the number of species, frequency of occurrence, projective cover and composition of bryocommunities and are indicators of the intensity of the influence of environmental factors in different types of forest ecosystems. Under the influence of climatic and anthropogenic factors, mosses form various reproductive systems and structural-functional and temporal variations of reproductive organs, which increases the success of fertilization depending on the availability of vital resources and water. Forest mosses are characterized by pronounced shade tolerance, the ability to productive photosynthesis in conditions of a low photosynthetically active part of the spectrum, as well as resistance to a lack of moisture and mineral nutrition elements in forest soils. In the gametophyte of forest mosses under adverse water supply conditions, a complex of protective physiological reactions was noted: an increase in overall antioxidant activity, as well as increased starch hydrolysis and accumulation of soluble carbohydrates, which provided intracellular osmoregulation and protection against oxidative damage. The environmental role of mosses in forest ecosystems consists in the formation of more favorable microconditions for the vital activity of plant cover due to the stabilization of the water-temperature regime of the upper soil layer, an increase in the acidity of metabolic processes of a predominantly neutral substrate, an increase in the content of organic carbon, ammonium and nitrate forms of nitrogen, and the development of soil microbiota.
