Pioneer psammophytic vegetation is usually developed on wind-drift sandy substrates such as arenas, spits, beaches, river terraces, and this vegetation occupies significant areas in all three natural zones of Ukraine. The Koelerio-Corynephoretea canescent... see more

The role of Cyanoprokaryota ecological groups in the ecosystems of the North Azov region was revealed in this work. On the territory of Pryazovskyi National Nature Park, 9 experimental polygons were studied, which covered steppe areas or slopes, salt mars... see more

Pioneer plant communities grow on newly-formed ecotopes of coastal and partially continental areas, on patches that have dried after the surface water flooding. They are affected by sea tides, wind-induced effect, salinity, denudation, accumulation and sh... see more

Waterbirds are vital indicators of anthropogenic influence on the ecological status of Mediterranean coastal lagoons. Our study relates temporal waterbird data to key environmental gradients at catchment scale that have a structural or functional influenc... see more

Increasing crop adaptability in terms of ensuring a stable level of productivity in the genotype – environment interaction is still the central problem of plant breeding theory and practice. The aim of the present study is to theoretically substantiate an... see more

It is well established that tree species grow within a realized niche. However, within that niche tree performance may not be equal. Therefore, we sought to quantify growth differentiation along elevational and climatic gradients in central Appalachia. A ... see more

In order to satisfy his needs, the man has to appropriate the nature. Of the two opposing modes of appropriation, the peasant and the agroindustrial, the least degrading is the first, in addition to being the most important because the volume of food prod... see more

AbstractGrazing intensity gradients were determined in the duneveld, river terrace and river bed habitats of the Kalahari Gemsbok National Park. Under increased grazing, a species composition characterised mostly by annual forbs and grasses results. In al... see more

Several ecological hypotheses try to explain geographical patterns in biodiversity. The Metabolic Theory of Ecology (MTE) predicts that temperature is the main determinant of richness patterns for ectothermic organisms and that the relationship between ri... see more
