The number of soil microorganisms that play a role in the organic matter decomposition process can be affected by litter quantity and quality. Lignin content is higher needleleaf than broadleaf. study aimed to determine bacteria found broadleaf forest at different depths. was collected depths 0-5 cm, 10-15 20-25 cm distance 1.5 m from canopy both coniferous forests where their locations are clo...
Increasing the prevalence of broadleaf trees in conifer-dominated production forests is a recommended means improving habitat availability for and mixed-forest species. The implications biodiversity are often measured by contrasting broadleaf-conifer mixtures with stands. However, few studies include broadleaf-dominated stands these assessments. Here we contrasted bird assemblages even-aged alo...
Dynamic global vegetation models are used to predict the response of vegetation to climate change. They are essential for planning ecosystem management, understanding carbon cycle–climate feedbacks, and evaluating the potential impacts of climate change on global ecosystems. JULES (the Joint UK Land Environment Simulator) represents terrestrial processes in the UK Hadley Centre family of models...
Phenological events, such as bud burst, are strongly linked to ecosystem processes in temperate deciduous forests. However, the exact nature and magnitude of how seasonal and interannual variation in air temperatures influence phenology is poorly understood, and model-based phenology representations fail to capture local- to regional-scale variability arising from differences in species composi...
BACKGROUND Although some studies have indicated that climate changes can affect Pinus koraiensis mixed forest, the responses of composition and structure of Pinus koraiensis mixed forests to climatic changes are unknown and the key climatic factors controlling the composition and structure of Pinus koraiensis mixed forest are uncertain. METHODOLOGY/PRINCIPAL FINDINGS Field survey was conducte...
We analysed chloroplast lipids of Nicotiana tabacum var. John William's Broadleaf, cultivated under an increased PCO(2) of 700 p.p.m. Glycolipids and phospholipids remain constant under these conditions, whereas the carotenoid content undergoes a quantitative change. The saturation degree of fatty acids increases due to an increase in palmitic acid and decreases in hexadecatrienoic acid and lin...
Qualitative characteristics of sugar beet as affected by different broadleaf herbicides combinations
ABSTRACT-Several herbicides are registered for selective weed control in sugar beet; however, no single chemical herbicide can control all weeds in beet fields. Frequently, two or more herbicides may have to be combined sequentially or as tank mixed to achieve adequate broad-spectrum weed control. In order to evaluate the effects of some combinations of broadleaf herbicides on sugar beet yield ...
