Plant hydraulic traits are key for understanding and predicting tree drought responses. Information about the degree of traits’ intra-specific variability may guide selection drought-resistant genotypes is crucial trait-based modelling approaches. For three temperate minor broadleaf species Acer platanoides, Carpinus betulus Tilia cordata, we measured xylem embolism resistance (P50), leaf turgo...
We report a simple fast, practical and effective method for the replication of the complex venation patterns of natural leaves into PDMSwith accuracy down to a lateral size of 500 nm. Optimising the amount of crosslinker enabled the replication and sealing of the microvascular structures to yield enclosed microfluidic networks. The use of plant leaves as templates for soft lithography was demon...
Abstract Tree allometry is a plastic feature, and scaling parameters can vary considerably depending on phylogeny, life strategies, growth conditions ontogeny. We hypothesized that in multi-layered forests growing rich sites driven by stand dynamics without stand-replacing disturbances, light primary driver of allometric relationships the morphological plasticity tree species closely associated...
according to coates’s (2004, as cited in zhang, 2010) definition of "conversational dominance" (p.111), it refers to the phenomenon of a speaker dominating others in interaction. specifically, it means how a speaker makes use of certain strategies to get the floor and maintain the floor. thus, the amount of talk is the main measurement for the dominance of the conversation. whether a speaker do...
Two-dimensional image conversion algorithms to 3D data create the hope that the structural properties of trees can be extracted through these images. In this study, the accuracy of biomass estimation in tree, plot, and hybrid levels using UAVs images was investigated. In 34.8 ha of Sisangan Forest Park, using a quadcopter, 854 images from an altitude of 100 meters above ground were acquired. SF...
Hurricane winds are one of the most important abiotic factors in shaping structure forest and processes that occur it. The aim research was to determine regeneration changes stands caused by windstorm 1983. research, based on stand tables from years 1982, 1984, 1989 2014, carried out nine permanent plots Bia?owie?a Forest. mean number trees (MNT) taller than 1.30 m decreased 13.7% after windsto...
Abstract Key message A vegetation analysis revealed the extent of recolonization by native a 25-year-old Cupressus spp. plantation in northern Iran. young indigenous Quercus-Carpinus community replaced conifers low-slope areas with deeper, heavier, and more fertile soils. Context Reforestation degraded or clear-cut-harvested lands can modify site conditions, facilitating succession reestablishi...
this study is an outlook of iranians religious practices and customs in eras such as nasser one. it attempts to answer the main question, "religious practices and ceremonies in the society during naseri ruling" and other subsidiary questions with scientific and historical theories. iran was a traditional and religious community . people abided by their religious practices and duties within reli...
nanotechnology is a general term which is related with field of all advanced science term that generally predicates with all modern technologies which consider nanoscales. improvement in the quality of products by adding some nanoparticles and study of their behavior in the presence of these nanoparticles have been obtained in many researches. on the other hand numerous demands for sowing ...
A significant loss of biodiversity resulting from human activity has caused biotic homogenisation to become the dominant process shaping forest communities. In this paper, we present a rare case of biotic differentiation in European temperate deciduous forest herb layer vegetation. The process is occurring in nutrient poor oak-hornbeam forests in mountain areas (Polish Eastern Carpathians, Cent...
