Threats, biodiversity drivers and restoration in temperate floodplain forests related to spatial scales

The efficiency of Thymus vulgaris, Lavandula angustifolia, and Cupressus sempervirens essential oils in suppression of Hymenoscyphus fraxineus on Fraxinus angustifolia seedlings

“…On the other hand, the Cupressus sempervirens L. (Cupressaceae) EO was chosen because it shows a significant application possibility against pathogenic bacteria genera Bacillus , Enterococcus , Escherichia , Pseudomonas , Staphylococcus , weeds Lolium rigidum, Phalaris canariensis, Phalaris paradoxa, Raphanus raphanistrum, Sinapis arvensis, Trifolium campestre , and fungi genera Aspergillus , Botrytis , Colletotrichum , Ganoderma , Gibberella / Fusarium , Hexagonia , Penicillium , Rhizoctonia , Rhizopus , and Microdochium in biotechnology (Amri et al., 2013; Badawy et al., 2017; Fitsev et al., 2022; Ismail et al., 2013; Mazari et al., 2010; Mohareb et al., 2013; Pansera et al., 2022). The species F. angustifolia , which is similarly sensitive as Fraxinus excelsior , was selected for testing EO in planta , whereby biological protection measures are of particular importance in protecting this tree species due to reducing the possibility of pollution and causing changes in diversity in floodplain forests which represent one of the most threatened ecosystems in the world (Havrdová et al., 2023).…”

Contrasting responses of forest phenological guilds to complex floodplain change

“…This is accompanied by the spread of pathogens such as Phytophthora alni and Hymenoscyphus fraxineus , resulting in higher tree mortality of alder and ash (Bjelke et al., 2016; Grosdidier et al., 2020), which are among the dominant tree species in floodplain forests. This interaction of the aforementioned factors is still yet unknown in floodplain vegetation (Havrdová et al., 2023).…”

“…However, the cessation of regular nutrient removal from forest ecosystems in the 20th century and the massive use of NPK fertilisers in the countryside led to a replenishment of nutrients. Specifically, floodplain forests located on the banks of large rivers were particularly affected by excessive nutrient inputs (Havrdová et al., 2023). Spring species appear to be quite nutrient demanding due to their rapid growth strategy and high photosynthetic rates that require high nitrogen and phosphorus inputs (Anderson & Eickmeier, 2000; Lapointe & Lerat, 2006; Merryweather & Fitter, 1995).…”

How Eutrophication Promotes Exotic Aquatic Plant Invasion in the Lake Littoral Zone?

“…Aquatic plant invasions pose a widespread and ever-increasing threat to lake ecosystems, e.g., by causing decline in biodiversity, habitat homogenization, and degradation of ecological functions. ,− In some cases, invasiveness of exotic species is dependent on the strength and type of stressor (e.g., nutrient enrichment and habitat destruction) as well as species composition and plant density in the invaded habitat. − Eutrophication leads to reduced submerged plant diversity and habitat damage, and in this way, it may produce ecological niche vacancies that are open for aquatic plant invasion. In general, lake eutrophication leads to an increase in nitrogen concentration and a decrease in light availability in the water column, subsequently causing nitrogen accumulation and carbon shortage in plants. − Under low light conditions, submerged plants usually elongate to reach the water surface in order to obtain more sunlight, while their biomass and ramet number usually show a decrease. , Changes in plant traits may affect plant invasiveness or their resistance to invasion.…”
