Kárász","doi":"10.21406/abpa.2022.10.22","DOIUrl":"https://doi.org/10.21406/abpa.2022.10.22","url":null,"abstract":": Serious oak decline was first detected in 1979-80 in a mixed sessile oak – Turkey oak forest ( Quercetum petraeae-cerridis Soó 1963). This decline resulted important structural changes in the understory shrub layer. Despite of this, relatively few studies deal with shrub communities and shrub layer dynamics after oak death. The goals of this research were to determine the conditions of low shrubs and analyse the possible changes in this layer after 5 decades from the beginning of Síkfőkút research. Specimens which were lower than 1.0 m in height were categorized as low shrubs in the shrub community. In 1972 and in 2022, 1617 native low shrub species were observed in the understory; 15 species were present continuously in the forest. The density of low shrubs was 87401 and 17317 specimen ha -1 . The most common low shrub species was Ligustrum vulgare and 5 decades later Quercus petraea with 24.1% and 37.8% ratio. The mean height and mean diameter of low shrub species changed among 10.3-67.0 cm and 1.5-7.5 mm. The mean cover of these shrubs fluctuated between 35 cm 2 and 2026 cm 2 based on the two measured year. Our results suggest that the low shrub layer responded negatively to the biotic and abiotic factors under 5 decades; this is especially true to the density, cover and diversity indices of species.","PeriodicalId":235732,"journal":{"name":"Acta Biologica Plantarum Agriensis","volume":"134 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124166762","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The relatively low temperature tolerance measured in default state (non energised thylakoids at full turgor) in the samples was inadequate to survive the thermal conditions of the original habitat. This was also manifested in the temperature sensitivity of optimal quantum yield (Fv/Fm) measured in dark-adapted state. The temperature dependence of the steady-state level of fluorescence, measured in light-adapted state, indicated a moderate decrease in heat sensitivity of PS II which was further enhanced by moderate water deficit. Moreover, a considerable water loss extremely increased the thermal stability of PS II in both dark and light-adapted states. Temperature dependence of the different quenching parameters suggests that in light-adapted state, the secondary effects of low lumen pH may protect against both temperature stress and water loss: i.e., it is likely that protection against the effects of light, temperature, and water deficit can be partly based on common bases. At very high temperatures the thermal damage of the oxygen-evolving complex is unlikely to be avoided, however, under continuous actinic light, the variable fluorescence (Fm’-Fs=AF) was partially recovered even above the critical temperature values of the Fs-T curves. This indicates the partial restoration of the electron donation of the PS II reaction centres by alternative electron donors. These changes in heat tolerance play a significant role to tolerate the effects of daily changing of the ecological factors in the habitat and it has a pronounced ecological significance and partly explains the survival of the examined crusts even under extreme semi-desert conditions.","PeriodicalId":235732,"journal":{"name":"Acta Biologica Plantarum Agriensis","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114275810","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Though terricolous lichens have a dominant role in semi-arid sandy grasslands, we still have limited information about these communities of dunelands and the environmental factors affecting assemblages in Europe, especially on calcareous sand. Besides, few studies have been focused on investigating the influence of microhabitat exposition on terricolous lichen community composition, to which dunes provide ideal locations. To fill in the mentioned knowledge gaps, we aimed to answer the following questions: a) what is the difference between the dune sides in species richness and composition and what kind of environmental variables could cause this difference? We studied the structure of the terricolous lichen assemblages of calcareous grasslands in an inland duneland ecosystem by comparing the lichen communities of the different dune sides. Microcoenological data were ascertained according to the Braun-Blanquet method. Environmental variables include the cover of bare soil, moss, litter, vascular plant cover and height of vascular plants. We investigated the relation of these variables and the presence and absence data of terricolous lichen species to the dune side. The investigation was completed with micrometeorological data collection to reveal the prevailing environmental conditions between the dunes. Our results showed that arid and humid dune sides host special lichen communities. Some lichen species were more abundant (e.g. Cladonia furcata ) or only found (e.g. Xanthoparmelia subdiffluens , Gyalolechia fulgens ) on arid dune sides. In contrast, others preferred (e.g. C. pyxidata ) or occurred only (e.g. Peltigera species, C. rei ) on humid sides. In general, lower vascular plant cover and height and a higher moss cover were characteristic of arid dune sides compared to humid sides, probably caused by the lower relative humidity and higher incoming irradiation (both in intensity and duration). The diverse microenvironmental conditions provide different microhabitat types; therefore, species with various ecological requirements can live together in the same habitat forming a species-rich and valuable terricolous lichen communities in inland dune ecosystems.","PeriodicalId":235732,"journal":{"name":"Acta Biologica Plantarum Agriensis","volume":"304 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116334847","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
