Effect of Successive Bleaching Treatments Followed by Staining on Color, Whiteness, and Translucency of Polymer‐Based CAD‐CAM Materials

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To evaluate differences in color, whiteness, and translucency of CAD‐CAM materials after successive bleaching treatments and coffee immersion. Materials and Methods Lava Ultimate (LU) and VITA Enamic (VE) were divided into four groups (n = 12): untreated (control), 35% hydrogen peroxide (WH), 10% carbamide peroxide (OP), or WH ...

Novel Hydrurus species (Chrysophyceae) and their adaptations to high‐altitude European and Arctic snowfields

Journal of Phycology, EarlyView.
Abstract Colored snow caused by green algae (Chlorophyceae) is well known, but melting snowpacks can also harbor golden‐brown blooms consisting of Chrysophyceae. We collected 14 samples of cryoflora in the Austrian and Swiss Alps, the High Tatras in Slovakia, and in Arctic Svalbard. Eight laboratory unicellular flagellated strains were established from

Reappearance of old growth elements in lowland woodlands in northern Belgium : do the associated species follow? [PDF]

, 2012
The forest cover of the western European lowland plain has been very low for centuries. Remaining forests were intensively managed, and old-growth elements like veteran trees and coarse woody debris became virtually absent.

Tree‐ring structure determines the temporal coordination between xylem growth and the gain in hydraulic conductivity in the outermost ring

New Phytologist, EarlyView.
Summary The study of seasonal xylem hydraulics has predominantly focused on embolism‐induced losses, whereas growth‐driven increases in hydraulic capacity have received little attention. We assessed the intra‐annual dynamics of xylem formation and gain of conductivity in the current‐year ring of three species with contrasting tree‐ring structure ...

Living \u3cem\u3eMore Than\u3c/em\u3e Just Enough for the City: Persistence of High-Quality Vegetation in Natural Areas in an Urban Setting [PDF]

, 2011
Urban environments pose special challenges to flora, including altered disturbance regimes, habitat fragmentation, and increased opportunity for invasion by non-native species. In addition, urban natural area represents most people’s contact with nature,

Non‐Additive Interactions Between Multiple Mutualists and Host Plant Genotype Simultaneously Promote Increased Plant Growth and Pathogen Defence

Plant, Cell &Environment, EarlyView.
ABSTRACT Understanding the impact of microbial interactions on plants is critical for maintaining healthy native ecosystems and sustainable agricultural practices. Despite the reality that genetically distinct plants host multiple microbes of large effect in the field, it remains unclear the extent to which host genotypes modulate non‐additive ...

Health Condition of European Beech (Fagus sylvatica L.) According to Provenances in International Provenance Trial

South-East European Forestry, 2012
The performance of European beech (Fagus sylvatica L.) is severely threatened by abiotic and biotic stresses, but the resilience of its provenances from distinct geographic areas has not been sufficiently studied.

De‐Coupled Water and Nitrogen Translocation From Subsoil to Canopy of Temperate Forest Trees

Plant, Cell &Environment, EarlyView.
ABSTRACT Water and nitrogen (N) transport from soil to canopy play a central role in tree functioning, yet direct evidence for their timing and coupling in mature forests remains scarce. We report results from a paired dual‐isotope (2H, 15N) tracer experiment in a temperate forest, comparing water and nitrate uptake patterns across tree species ...

Variations in Proline Content, Polyamine Profiles, and Antioxidant Capacities among Different Provenances of European Beech (Fagus sylvatica L.)

Antioxidants
International provenance trials are a hot topic in forestry, and in light of climate change, the search for more resilient beech provenances and their assisted migration is one of the challenges of climate-smart forestry. The main aim of the study was to
