We investigate the impact of a 20-yr irrigation on root water uptake (RWU) and drought stress release in a naturally dry Scots pine forest. We use a combination of electrical resistivity tomography to image RWU, drone flights to image the crown stress and sensors to monitor soil water content. Our findings suggest that increased water availability enhances root growth and resource use efficiency, potentially increasing trees' resistance to future drought conditions by enabling water uptake from deeper soil layers. This research highlights the significant role of ecological memory and legacy effects in determining tree responses to environmental changes.

Biopolymers derived from natural sources are sustainable, non-toxic, and biodegradable, making them attractive alternatives to fossil-based polymers. Among these, lignin has garnered significant attention due to its potential in adhesive applications. In this study, lignin was extracted from redwood ( L.

This study investigates the diversity and distribution of fungi in var. (PSM) forests across Inner Mongolia, with a focus on understanding the environmental factors influencing fungal communities. High-throughput sequencing was utilized to analyze soil fungal communities across 12 PSM forest sites, alongside assessments of meteorological variables and soil enzyme activities.

Terrestrial ecosystems are a key component in the biogeochemical cycle of Hg. About 50% of atmospheric Hg is captured in the system because of the ability of vegetation to retain and subsequently transfer it to the soil surface through litterfall. In a stand dominated by Scots pine (Pinus sylvestris), the widest spatially distributed tree species in the northern hemisphere and the second worldwide, this two-year study evaluated monthly the litterfall Hg deposition fluxes (FHg) through all litterfall fractions involved (needles, twigs, bark, miscellaneous, and male inflorescences).

Pulse-amplitude modulated (PAM) chlorophyll fluorescence (ChlF) measurements provide a non-invasive method to study the regulation of the light reactions of photosynthesis in situ. PAM ChlF contributes also to the advancement of the interpretation of long-term observations of remotely sensed solar induced fluorescence by revealing the mechanistic connection between ChlF and photosynthetic function. However, long-term field PAM ChlF measurements remain uncommon due to challenges associated with the outdoor environment, instrument installation and maintenance, or data processing and interpretation.

Digital Volume Correlation (DVC) was used to study the hygroscopic shrinkage in lignocellulosic tissues. For this, small tissue segments of only a few cells were prepared from the endocarp of fruits, the sclereid cell layer of pine cone scales, the sclerenchyma fiber sheath of peripheral vascular bundles in and latewood of . The cells were imaged in a wet and dry state using X-ray nano-holotomography.
