A great number of limit values has been introduced through statutory regulations in recent decades, in order to put constraints on the exposure to toxic agents at the workplace and in the environment. As far as these limits have been determined on the ba
Within the same genus the enantiomeric ratio of these compounds can be different. Thus, the determination of enantiomers is a valuable tool to evaluate authenticity and quality of EOs. In here, the terpene profile of primary and commercial pine EOs was analyzed by conventional and chiral gas ...
LiPhe position is represented by the black triangle, while, the tree species are represented by blue, magenta and yellow dots, corresponding to Scots pine, Norway spruce, and silver birch, respectively. Fig. 1 LiPheStream dataset on the map: (a) Approximate location of Hyytiälä forest ...
such as gross primary production (GPP, i.e., gross carbon uptake by plants)6, has led to a particularly wide variety of indices. The NIR Reflectance of Vegetation (NIRv)21as well as the generalized Kernel NDVI (kNDVI)22are examples of novel indices that aim to serve ...

The leathery, sessile, simple leaves are elliptical, ovate, linear or lanceolate and wedge-shaped at the base. The leaf blade is dorsiventral, medium-sized to large and disposed oppositely or in a whorl and with entire margin. The leaf venation is pinnate, with numerous veins ending in a...
Other nematodes attack bark and forest trees. The most important representative of this group is Bursaphelenchus xylophilus, the pine wood nematode, present in Asia and America and recently discovered in Europe. Agriculture and horticulture Depending on its species, a nematode may be beneficial or det...
Arhopalus rusticus is a suspected vector of the phytopathogenic nematode, Bursaphelenchus xylophilus, the causative agent of pine wilt disease, which is a major threat to pine forests worldwide. Here, we report the identification of a volatile, male-produced aggregation-sex pheromone for this ...
