The abandonment of agricultural use of drained fen peatlands contributes to intensified moorshing process and, consequently, faster of wetlands areas degradation. Peat mineralization causes the eutrophication of the habitat which, along with changing humidity, enables the presence of so-called non peat-forming plants. Among the seeds and fruit present in the top layer of degraded marshy soils, there...
The cause of seed dormancy relief may be various external factors, however the most data suggest particular role of temperature, especially it is seasonally changing environmental cue. The impact of temperature on hydrotime model parameters of red clover seeds has not been studied up to date. The aim of the study was to determine the water relations of red clover seeds during germination after different...
The aim of this study was to explore ecological adaptation of seed microsculptures of Saussurea from different altitudes. Scanning electron microscopy was used to observe the cypselae surface of 10 taxa of Saussurea collected from the eastern edge of Qinghai-Tibet plateau, China. The results indicated that the microsculptures had clear and consistent variations in some samples collected from high...
Seed-eating birds may consume seeds in the tree (pre-dispersal predation) as well as on the ground (post- dispersal predation), usually at contrasting microhabitat conditions. We examined the foraging behaviour and contribution to seed predation of a whole assemblage of seed-eating birds (mostly Fringillidae) at both dispersal phases (pre- and post-dispersal) in a wind-dispersed tree, the European...
Pharmaceuticals have become an emerging environmental protection problem due to their presence in water and soil ecosystems. Reliable cell viability biomarkers (mitochondrial and cytosol distribution of cytochrome c oxidase activity), germination, and growth of seedlings were assessed to be sensitive endpoints of diclofenac toxicity. Moreover, the content of soluble carbohydrates in seedlings of three...
