Land use may be regarded as one of the most important factors affecting theenvironment with respect to human activities. So far, destroying the rangelands andchanging them into the waste lands and poor rangelands has been proposed as the mostsignificant variations of land use done by human beings. This paper has been conducted toevaluate the variations of vegetation percentage and land uses in ...

High variability due to soil heterogeneity and climatic conditions challenge measurement of greenhouse gas (GHG) emissions as influenced by management practices in the field. To reduce this variability, we examined the effect of management practices on CO2, N2O, and CH4 fluxes and soil temperature and water content from July to November, 2011 in a greenhouse. Treatments were incomplete combinat...

The flora of willow (Salix viminalis L.) plantations consists various plant groups, including plants related to arable land, called segetal plants. Knowledge this is important for maintaining biodiversity in agroecosystems. aim the study was assess central Poland, depending on land use before establishment (arable or fallow) and age plantations. Moreover, also check presence invasive, medicinal...

n the Northeast Himalayas (NEH) region, four major conventional land-use types are forest, Jhum lands, fallow lands and plantations, but little is known about their sustainability responses to changes. We collected soil samples at two uniform depths (0-15 15-30 cm) from Zunheboto district of Nagaland (India). The dataset was statistically analyzed by conducting an ANOVA-one way, principal compo...

The enzyme-linked immunosorbent assay (ELISA) is the diagnostic test most commonly used in efforts to control paratuberculosis in domestic ruminants. However, commercial ELISAs have not been validated for detecting antibodies against Mycobacterium avium subsp. paratuberculosis in wild animals. In this study, we compared the sensitivities and specificities of five ELISAs using individual serum s...

The article tackles the impacts of anthropogenic load on physical and hydrophysical soil properties. In order to better comprehend processes spontaneous sylvatisation in a mountain region (the Pohartsi boundary, Koziova village, Skolivski Beskydy physiographic region) four study plots were selected representing successional sequence: forest → pasture hay meadow arable lands. Land patches that a...

This paper describes the course and variation in the brain base arteries in fallow deer. The metrical features of the brain base arteries were determined with an image analysis system. The main sources of blood supply to the brain in fallow deer are internal carotid arteries; vertebral arteries rarely participate in blood supply. The brain base arteries in fallow deer show variation both in the...

Slash-and-burn agriculture is a sequence of interactions between farmers and ecosystems, which includes forest, cropping, fallow, and cropping after fallow. In sampling across this sequence in Pucallpa, Peru, 235 plant species were recorded in the forest, of which 143 were not found in any successive land use. However, plants not occurring in the forest colonized fields and fallow. In total, 59...
