The present study has been done to evaluate the impact of pure ash stand and mixed stand with beech on the herb layer biodiversity and soil properties in the forests of Noor city. There is a unique s...
An experiment was conducted to investigate the environment of the deep litter system and provided theoretical basis for production.
Fagus sylvatica Linnaeus (European beech), the ecologically and economically most important broadleaved tree species in the Czech Republic, was strongly reduced in the past. Today there are efforts to...
近日,由中国科学院昆明植物研究所和中国植物学会主办的英文期刊Plant Diversity 极小种群野生植物专刊正式出版。受该刊主编周浙昆研究员和Sergei Volis教授的邀请,由昆明植物研究所孙卫邦研究员任Guest Editor-in-Chief, 力图展现极小种群野生植物的热点问题和最新进展。
 The genome of the corn plant – or maize, as it’s called almost everywhere except the US – “is a lot more exciting” than scientists have previously believed. So says the lead scientist in a new e...
Japanese quail is still used as a model for poultry research because of their usefulness as laying, meat, and laboratory animals. Microsatellite markers are the most widely used molecular markers, due...
This study was aimed to evaluate the in vitro effects of medicinal herb extracts (MHEs) on ruminal fermentation characteristics and the inhibition of protozoa to reduce methane production in the rumen...
Premise of the study : Elucidating the factors that determine the abundance and distribution of species remains a central goal of ecology. It is well recognized that genetic differences among indivi...
Castor (Ricinus communis L.) is an industrial oilseed crop grown worldwide. Its oil with more than 80% ricinoleic acid makes it a chief raw material for numerous industrial applications and biofuel ...
Taxonomical bias for the intensity of research in natural sciences is well documented but less data exists for crop protection, weed and phytopathology sciences. Here we test a hypothesis predicting a...
Polymorphic SNPs were identified using BovineSNP50 BeadChip in three groups of cervids: farmed Red deer (n = 3), and free range Red deer (n = 5) and Fallow deer (n = 2). From the total of 54 609 SNPs,...
The simple sequence repeats (SSR) method of DNA analysis was used to determine genetic diversity within and among silver fir (Abies alba Mill.) populations. Total genomic DNA was extracted from 250 Ab...
The Bulgarian Grey Cattle (BGC) and Shorthorn Rhodopean Cattle (SRC) are indigenous breeds from the Balkan Peninsula region. The Balkans, as part of Southeast Europe, is a crucial civilization cross...
