Does cultivation influence the content and pattern of soil proteins

Journal Articles & Books
December, 2011
Iran

Proteins comprise one of the largest N inputs to soils. There is, therefore, a need to investigate the factors involved in the inputs and fate of proteins in soil. While land use management is expected to influence the amount and diversity of soil proteins, the responses of protein as a source of mineralizable N to land use changes have not yet been studied. We hypothesized that extractable soil protein could be a sensitive indicator in evaluating the effect of stress in ecosystem.

The management and classification of the typical soils of the Yıldız Forest Ecosystem

Policy Papers & Briefs
December, 2009
Turkey

The soils of the Yıldız Mountain, namely Entisols, Mollisols, Inceptisols, Ultisols, and Spodosols, from Poyralı, Yeniceköy, Demirköy and northwest of Igneada that were developed on calcareous sandy sediments, chlorite schists, Pliocene sediments and alluvial materials were studied in this paper.

Organizational and economic mechanism of agricultural land use planning regulation with the aim to increase land use efficiency

Policy Papers & Briefs
December, 2011
Belarus

In course of the research there was studied the theoretical bases of organizational and economic mechanism of land use regulation, which include the notions, principles, requirements, factors and criteria. The conceptual scheme and the model of functioning of the organizational-economic mechanism were developed. Study was realized in the conditions of the Republic of Belarus.

Ecosystem structure, function, and composition in rangelands are negatively affected by livestock grazing

Journal Articles & Books
December, 2016
Australia

Reports of positive or neutral effects of grazing on plant species richness have prompted calls for livestock grazing to be used as a tool for managing land for conservation. Grazing effects, however, are likely to vary among different response variables, types, and intensity of grazing, and across abiotic conditions. We aimed to examine how grazing affects ecosystem structure, function, and composition. We compiled a database of 7615 records reporting an effect of grazing by sheep and cattle on 278 biotic and abiotic response variables for published studies across Australia.

Improvement of land-property relations in the direction of further liberalization of economic activity

Policy Papers & Briefs
December, 2011
Belarus

In course of the research there was studied the system of measures of liberalization of conditions for business activity actualization in the conditions of the Republic of Belarus. The liberalization management of conditions of realization of economic activities (which include the use, estimation of conditions and protection of land resources of Belarus) is expedient to consider in two directions which are inseparably interlinked.

model of gas mixing into single-entrance tree cavities during wildland fires

Journal Articles & Books
December, 2011

The level of protection to fauna provided by tree cavities during wildland fires is not well understood. Here we present a model for estimating the transport of combustion gases into cylindrical, single-entrance cavities during exposures caused by different wildland fire scenarios. In these shelters, the entrance occurs near the top of the cavity.

Early succession arthropod community changes on experimental passion fruit plant patches along a land-use gradient in Ecuador

Journal Articles & Books

Ecuador

Many tropical landscapes are today characterized by small forest patches embedded in an agricultural mosaic matrix. In such highly fragmented landscapes, agroforests have already been recognized as refuges for biodiversity but few studies have investigated the potential of non-forested land-use types to contribute to overall biodiversity of functionally important taxa in the tropics.

Spatial dependence of predictions from image segmentation: A variogram-based method to determine appropriate scales for producing land-management information

Journal Articles & Books
December, 2010

A significant challenge in ecological studies has been defining scales of observation that correspond to the relevant ecological scales for organisms or processes of interest. Remote sensing has become commonplace in ecological studies and management, but the default resolution of imagery often used in studies is an arbitrary scale of observation. Segmentation of images into objects has been proposed as an alternative method for scaling remotely-sensed data into units having ecological meaning.

Inorganic nitrogen, sterols and bacterial source tracking as tools to characterize water quality and possible contamination sources in surface water

Journal Articles & Books
December, 2012
Canada

The effects of agricultural activities on stream water quality were assessed by nitrogen analysis, further investigated by gas chromatography mass spectrometry (GC-MS) sterol analysis (including chemometric analysis), and characterized by bacterial source tracking (BST). Surface water samples were collected from five sites, throughout the agriculturally-influenced Nathan Creek watershed, British Columbia, Canada and a nearby control site between October 2005 and March 2006.
