Abstract:
... The determination of tree age is an important issue for urban green planning, forestry and dendrology; finding non-destructive and quasi-non-destructive methods for this purpose is of great theoretical and practical importance. The resistance drilling method is quasi-non-destructive because the average diameter of an opening that remains after drilling does not exceed 3 mm. Do electrically recordi ...

Abstract:
... How much a plant is attacked by insect herbivores likely depends on its apparency and ability to produce defensive traits, which may be modified by neighbouring plants and abiotic conditions. Yet, how much the direct and trait‐mediated effects of neighbours on herbivory is modified by abiotic factors is still unknown. By using a tree diversity experiment in SW France, we measured leaf insect herbi ...

Abstract:
... Silver birch, (Betula pendula), is an important forest tree species in Poland used for afforestation in rural areas and planted in wet forest types to ameliorate excess water. Physiological stress may increase susceptibility of trees to disease and it is hypothesized that insect defoliation can predispose birch to Phytophthora plurivora infection. In order to evaluate the effect of defoliation str ...

In addition, tree species effect was studied in one site that included Norway ...

Abstract:
... Symbiosis with microbes is crucial for survival and development of wood-inhabiting longhorn beetles (Coleoptera: Cerambycidae). Thus, knowledge of the endemic fungal associates of insects would facilitate risk assessment in cases where a new invasive pest occupies the same ecological niche. However, the diversity of fungi associated with insects remains poorly understood. The aim of this study was ...

The study focused on the vascular species of herb layers in young forest stands ...

INTRODUCTION: In ecological experiments, storage of plant material is often needed between harvesting and laboratory analyses when the number of samples is too large for immediate, fresh analyses. Thus, accuracy and comparability of the results call for pre‐treatment methods where the chemical composition remains unaltered and large number of samples can be treated efficiently.

Abstract:
... MAIN CONCLUSION: The approach presented here can be applied to reduce the time needed to introduce traits from wild apples into null segregant advanced selections by one-fourth. Interesting traits like resistances to pathogens are often found within the wild apple gene pool. However, the long juvenile phase of apple seedlings hampers the rapid introduction of these traits into new cultivars. The r ...

Application of the most productive genotypes is essential. However, information about genetic gains in low-density plantations is still lacking. A 40-year-old low-density (400 trees ha−1) plantation of 22 grafted silver birch plus-tree clones ...

If residues are combusted for energy, their carbon content is released immediately. Residues, that are not combusted, decompose and emit carbon gradually. The relative harmfulness of bioenergy emissions therefore depends on how strongly we prefer the slow release of carbon to an immedia ...

Abstract:
... This study presents an analysis of the relationships among tree species, the type of mine soil substrate vs. vegetation development and features of plant communities. The study was conducted on two types of afforested mine sites (open strip sulphur and sand pit mine) built from various parential rocks: mixed quaternary sands and Neogene clays (QsNc) and quaternary loams (Ql). The study plots were ...

Whether trees have the ability to refill embolised xylem conduits and possibly to do it under tension, i.e., in a physiologically active state, has been a topic of research and debate for many years. However, direct experimental evidence for embolism refilling remains scarce. Combining traditional tree hydraulic methods (e.g., hydraulic conductance measurements on excised stems), new approaches (c ...

Abstract:
... Browsing effects of voles on plants can be mitigated by means of non-lethal predation, i.e. by subjecting voles to predator cues. Earlier studies largely focused on mammalian olfactory cues, whereas here we exposed Microtus voles to owl calls to examine whether the introduced predation risk reduces browsing on tree seedlings (silver birch, Scots pine, Norway spruce). We found that owl risk was ass ...

As an immediate response in certain tree species, spring phenological phases, such as budburst and flowering, have tended to occur earlier. However, recent studies have shown a slowing down of phe ...
