A study was conducted at the tropical dry forest of Bandipur, south India, to understand the impact of dry season fire on survival and mortality of different species. A total of 4235 trees belonging to 66 species were enumerated in both burnt and un-burnt areas of Bandipur National Park. Standard vegetation indices were calculated to characterize the natural vegetation of the...
Vegetation classification for any area involves analysis of trees, shrubs and ground cover. These strata are the primary features to characterize the vegetation. Species density and diversity depends on several topographic and climatic variations. Patterns of species density, richness and diversity of different vegetation types were analyzed in Bijrani, Serpdulli and Dhikala...
In this study we assessed the tree ring structure modifications and the relation with climate in Scots pine from Aleșd region (Romania). Tree rings structures were analysed based on microscopic sections obtained from the core sample. The analysis on the area of the incomplete lignified cells (IC) and the lignified cells (CL) was made. The results show a high frequency of false...

In this study, the influence of moisture content on some orthotropic mechanical properties of sessile oak which is one of the most important wood species grown in Turkey and common in the furniture industry have been investigated. The properties studied include Young’s modulus, Poisson’s ratios and compression strength of oak wood in three anatomical directions. These properties...
Understanding the distribution of individual species and the factors affecting their distribution is a key issue in biogeography, ecology and conservation. This study was carried out to determine bioclimatic factors affecting the two pedunculate oak subspecies ( Quercus robur L. subsp. robur and Q. robur subsp. pedunculiflora (K.Koch) Menitsky ) of Turkey and their tolerances to...
Abstract The study has been carried out in Dhanaulity region of temperate forest of Garhwal Himalaya to underestnad litter production, their decodmpstion and concetraion of nutrients release by leaf litter at different altitudes. The results indicate that the litter production with altitude in each season reduced in order of Lower>middle>upper altitudes, while in each altitudes...
The annual pollen influx in the altitudinal zone 1 800 - 20 50 m a.s.l. produced by plant communities in the coniferous and subalpine vegetation belts of the northwestern Rila Mts. was analyzed for the period 1994-2008 . The results from the five pollen traps placed on south and north slopes of a ridge revealed the dominance of Pinus diploxylon -type ( Pinus mugo, Pinus...
Bu çalışmada Türkiye’de yetişen önemli ağaç türlerimizden olan ve mobilya sanayisinde yaygın kullanılan sapsız meşe (Quercus petrea) odununun bazı ortotropik mekanik özellikleri üzerine rutubetin etkisi incelenmiştir. Çalışmada kayın odununun lif, radyal ve teğet yönlerdeki Young modülü, Poisson oranları ve basma dirençleri incelenmiştir. Bu özellikler sonlu elemanlar gibi üç...

Bu çalışma Garhwal Himalaya’nın Dhanaulity bölgesindeki ılıman kuşak ormanlarındaki ölü örtü birikimi, ölü örtü ayrışması ve böylece ölü örtüden besin maddelerinin salımı miktarlarını belirlemek amacıyla yapılmıştır. Araştrıma sonuçları, ölü örtü miktarları en yüksekten en düşüğe doğru alt>orta>üst yükseltilerde olduğu ve herbir yükselti basamağında yaz>yağmurlu mevsim>kış...
Rila Dağı 1800-2050 m yükseltileri arasındaki zirve altı kuşaktaki bitki toplumlarının ve iğne yapraklı ormanların 1994-2008 yılları arasındaki polen dağılımları incelenmiştir. Sırtların kuzey ve güney bakılarından toplanan toplam 5 adet polen kapanlarından elde edilen bulgulara göre en hâkim türlerin Pinus diploxylon-tipi (Pinus mugo, Pinus sylvestris) ve yoğun çiçeklenme...

This study is performed in Nevşehir province at central Anatolian parts of Turkey. The aim of the current study was to investigate the yearly changes of rainfall and temperature climatic parameters in the long data period from 1975 up to 2014 years. The total of 40 years precipitation and temperature monthly data were first separated and classified seasonally and then were...
Deciduous roadside vegetation exhibits seasonal patterns of foliage with varying colors and numbers. Hence the alternating percentage of the gaps within the roadside canopy allows changing percentages of light transmission throughout the year. The leafless roadside vegetation in winter is sequentially subject to budburst, flushing, and development stages until the summer, when...
