Abstract Aims We examined differences in life span among the dominant tree species (spruce, Picea abies ; fir, Abies alba beech, Fagus sylvatica and maple, Acer pseudoplatanus ) across primary mountain forests of Europe. asked how disturbance history, lifetime growth patterns, environmental factors influence span. Locations Balkan Mountains, Carpathian Dinaric Mountains. Methods Annual ring widths from 20,600 cores were used to estimate spans, trends, history metrics. Mixed models examine...
Biological invasions pose an increasing risk to nature, social security and the economy, being ranked amongst top five threats biodiversity. Managing alien invasive species is a priority for European Union, as outlined in EU Biodiversity Strategy 2030 Kunming-Montreal Global Framework. Alien plant are acknowledged impact economy biodiversity; thus, analysing distribution of such provides valuable inputs management decision-making processes. The database presented current study first...
Shape is a fundamental morphological descriptor, significant in taxonomic research as well ecomorphology, one method of estimation being from digitally processed images. In the present study, were analysed shapes of Q. petraea crowns, pertaining to five different stem diameter classes, three similar stands. Based on measurements terrestrial digital vertical photos, crown size analysis was performed and correlations between variables tested. Linear regression equations volumes dbh, derived,...
Eigenshape analysis and Relative Warp Analysis were employed in the study of shape highly variable sporangia Phytophthora plurivora, a widespread oomycetous pathogen isolated from woody species, several South-East European countries: Bulgaria, Greece, Serbia Romania. The aim was to estimate whether variables permitted quantitative assessment sporangial variability P. plurivora also, discrimination between species based solely on shape, cactorum being selected for comparisons. Both Analyses...
Facilitation is a positive interaction demonstrated to be one of the important factors shaping regeneration niche trees, mostly under stressful conditions which currently studied in frame complex ecological networks. The protection provided by benefactor plants for tree seedlings playing role beneficiaries documented mainly arid and semi-arid habitats or situations where herbivores’ pressure constitutes main factor regeneration. One iconic Transylvanian landscapes wood-pasture, also oldest...
The trade with cultivated plants is one of the major pathways for introduction invasive species, pathogens included. Based on network analysis, present study aimed interaction between several species woody perennials found in gardening outlets and nurseries trading ornamental their documented pathogens. Focal host list were Thuja plicata, Buxus sempervirens Prunus laurocerasus, selection being based reported bestselling figures. Bipartite, qualitative, undirected networks constructed to...
The primary pathogen responsible for the green alder (Alnus alnobetula (Ehrh.) K. Koch subsp. alnobetula) decline in two mountain ranges pertaining to Eastern Carpathians and harbouring protected areas, Călimani Mountains National Park Rodnei was identified as stem branch canker dieback agent, Valsalnicola oxystoma (Rehm) D.M. Walker & Rossman (Melanconidaceae, Diaporthales). identification based on situ observations cultivation PDA medium of diseased inner bark fragments. Field...
Simulations and modeling represent modern research methods appropriate for the long perspective management planning. In forestry domain, simulation of different silvicultural interventions have outstanding importance in process proposal adoption stand regimes, biodiversity conservation, forest products optimal valorization finally, sustainable resources.
