Airborne remote sensing data from different types of sensors are tested within the Bavarian Forest National Park for estimation of forest attributes using several analysis methodologies. In this study, one algorithm that earlier has been validated for Swedish conditions was applied. The algorithm estimates tree position, tree height, and crown diameter of individual trees. The Bavarian Forest N...
The impacts of fragmentation and recreational use on the hemiboreal urban forest understorey vegetation and the microbial community of the humus layer (the phospholipid fatty acid (PLFA) pattern, microbial biomass and microbial activity, measured as basal respiration) were examined in the greater Helsinki area, southern Finland. Trampling tolerance of 1) herb-rich OMT, 2) mesic MT, and 3) sub-x...
Genetic Variability and Structure of The Wild Service Tree (Sorbus torminalis (L.) Crantz) in Poland
فلزات سنگین به دلیل سمیت و پایداری یکی از مهمترین مسایل محیطزیستی محسوب میشوند. در این مطالعه برای درک میزان مخاطرات ناشی از فلزاتسنگین، غلظت برخی فلزات سنگین (آلومینیم، آهن، منگنز، کروم، وانادیم، نیکل، روی، آرسنیک، مس، سرب، کبالت، و کادمیم) در رسوبات سطحی 11 ایستگاه در خلیج چابهار توسط دستگاه اسپکترومتری نشری پلاسمای جفت شونده القائیICP OES)) تعیین شدند. ایستگاه های نمونه برداری شامل ورود...
The present study focused on the examination of seed and pollen morphology nine native Chinese species genus Sorbus L. using Light Microscope (LM) Scanning Electron (SEM). crucial features investigated for seeds include color, shape, epidermal cell size, coat ornamentation. On other hand, grains are analyzed based quantitative traits as well following traits: polar equatorial view, apertures ex...
We describe the "landscape trap" concept, whereby entire landscapes are shifted into, and then maintained (trapped) in, a highly compromised structural and functional state as the result of multiple temporal and spatial feedbacks between human and natural disturbance regimes. The landscape trap concept builds on ideas like stable alternative states and other relevant concepts, but it substantiv...
Rowan species (genus Sorbus L., Rosaceae Juss.) are widespread in the Northern Hemisphere under different climatic and ecological conditions. Recent molecular-phylogenetic studies confirmed that genus L. is polyphyletic must be divided into segregate genera. Accordingly, native for Ukrainian flora domestica torminalis (L.) Crantz., having very distant morphological features of vegetative genera...
The aim of the study was to analyze influence dimensions extraction cells on energy aspects and efficiency flavonoids from rowanberry fruits (S. aucuparia L.). total flavonoid content determined using spectrophotometric method. Response surface methodology (RSM) used optimize variables under investigation. in obtained extracts ranged 0.17 0.66 mg QE/g dry matter for with a diameter 3.5 cm, 0.19...
