Although night-time water relations have been studied in different plant species in the last decade, there is limited information about the impact of climate variables on endogenous regulation of night-time water relations in trees. The aim of the current study was to elucidate how long-term...

The study was performed on coppice shoots and 9-year-old saplings of hybrid aspen (Populus tremula L. × Populus tremuloides Michx.) growing at the Free Air Humidity Manipulation site in 2013 and 2014. The main aims of our study were to determine the differences in water potentials between soil and...

Biomass and area ratios between leaves, stems and roots regulate many physiological and ecological processes. The Huber value H_v (sapwood area/leaf area ratio) is central to plant water balance and drought responses. However, its coordination with key plant functional traits is poorly understood,...

Due to massive energetic investments in woody support structures, trees are subject to unique physiological, mechanical, and ecological pressures not experienced by herbaceous plants. Despite a wealth of studies exploring trait relationships across the entire plant kingdom, the dominant traits...

Volatile emissions from urban parks and forests can significantly contribute to local and regional air quality due to biogenic volatile organic compound (BVOC) emissions from vegetation, but the source strength of BVOC of urban habitats is difficult to assess due to a complex mixture of ornamental...

Plants in Mediterranean ecosystems face multiple environmental stresses during the growing season. Such stresses greatly affect ecosystem function, but are poorly represented by current ecosystem models. Here, we review recent advances in understanding the responses of ecosystem photosynthesis to...

Methyl jasmonate (MeJA) is an airborne hormonal elicitor that induces a fast rise of emissions of characteristic stress marker compounds methanol and green leaf volatiles (GLV), and a longer-term release of volatile terpenoids, but there is limited information of how terpene emissions respond to...

At northern latitudes, a rise in atmospheric humidity and precipitation is predicted as a consequence of global climate change. We investigated the impact of high (H) and moderate (M) daytime air relative humidity (RH) on water relation parameters and foliar nutrient status in saplings of silver...

Stoichiometry of leaf macronutrients can provide insight into the tradeoffs between leaf structural and metabolic investments. Structural carbon (C) in cell walls is contained in lignin and polysaccharides (cellulose, hemicellulose, and pectins). Much of leaf calcium (Ca) and a fraction of...

Bamboo is an important component in subtropical and tropical forest communities. The plant has characteristic long lanceolate leaves with parallel venation. Prior studies have shown that the leaf shapes of this plant group can be well described by a simplified version (referred to as SGE-1) of the...
