Vegetation‐environment relationships in Atlantic European calcareous grasslands

Journal Articles & Books
Diciembre, 2000
Francia
Irlanda
España

The relationship between vegetation and environment was investigated for calcareous grasslands in a region in the west of Spain, France, Britain and Ireland defined by climatic criteria. Vegetation was sampled using objective methods and data collected on soils, land cover, location and management. Climate data were obtained from an available database. Examination of the first axis of vegetation variation as defined by Detrended Correspondence Analysis (DCA) showed a gradient from the Irish and British samples to those from France.

global land-cover validation data set, II: augmenting a stratified sampling design to estimate accuracy by region and land-cover class

Journal Articles & Books
Diciembre, 2012

A global validation database that can be used to assess the accuracy of multiple global and regional land-cover maps would yield significant cost savings and enhance comparisons of accuracy of different maps. Because the global validation database should expand over time as new validation data are contributed, the sampling design must be constructed so that it is simple to increase the sample size from a specific region (e.g. a continent or country) or from targeted land-cover classes to improve standard errors of the accuracy estimates.

Performance of indicators and the effect of grain size in the discrimination of plant communities for restoration purposes

Journal Articles & Books
Diciembre, 2008
Italia

There is strong pressure to embrace indicators for practical goals such as nature conservation and management and to evaluate the restoration success, but the selection of appropriate indicators is not straightforward. In addition, the grain and the type of data collected and data transformation adopted can influence restoration monitoring results. In this paper, we assessed the effect of changing indicator, grain size (i.e., plot dimension) and data transformation in discriminating different mapped plant communities, relying on vascular plant composition data.

Principles for life cycle inventories of land use on a global scale

Journal Articles & Books
Diciembre, 2013

PURPOSE: To assess the diverse environmental impacts of land use, a standardization of quantifying land use elementary flows is needed in life cycle assessment (LCA). The purpose of this paper is to propose how to standardize the land use classification and how to regionalize land use elementary flows. MATERIALS AND METHODS: In life cycle inventories, land occupation and transformation are elementary flows providing relevant information on the type and location of land use for land use impact assessment.

Accessibility as a determinant of landscape transformation in western Honduras: linking pattern and process

Journal Articles & Books
Diciembre, 2003
Honduras

This study evaluates the relationship between landscape accessibility and land cover change in Western Honduras, and demonstrates how these relationships are influenced by social and economic processes of land use change in the region. The study area presents a complex mosaic of land cover change processes that involve approximately equal amounts of reforestation and deforestation.

Incorporating Risk of Reinvasion to Prioritize Sites for Invasive Species Management

Journal Articles & Books
Diciembre, 2014
Estados Unidos de América
Global

The relationship between landscape pattern and the distribution and spread of exotic species is an important determinant of where and when management actions are best applied. We have developed an interdisciplinary approach for prioritizing treatment of harmful, nonnative, invasive plants in National Park landscapes of the Mid-Atlantic USA.

Land cover mapping applications with MODIS: a literature review

Journal Articles & Books
Diciembre, 2012

Land use/land cover monitoring and mapping is crucial to efficient management of the land and its resources. Since the late 1980s increased attention has been paid to the use of coarse resolution optical data. The Moderate Resolution Imaging Spectroradiometer (MODIS) has features, which make it particularly suitable to earth characterization purposes. MODIS has 10 products dedicated mainly to land cover characterization and provides three kinds of data: angular, spectral and temporal. MODIS data also includes information about the data quality through the ‘Quality Assessment’ product.

Badger (Taxidea taxus) Resource Selection and Spatial Ecology in Intensive Agricultural Landscapes

Journal Articles & Books
Diciembre, 2014

American badgers (Taxidea taxus) are a prairie obligate species, but badger resource selection and space use is poorly understood, particularly east of the Mississippi River where anthropogenic land uses have replaced most native prairie. We assessed badger multi-scale resource selection and space use in intensive agricultural areas in Illinois and Ohio. We predicted that badgers would select for pasture and prairie, and higher elevations, and riparian areas because these habitats likely favor burrowing and foraging.

264 years of change and persistence in an agrarian landscape: a case study from the Swiss lowlands

Journal Articles & Books
Diciembre, 2015
Europa

CONTEXT: Century-long interaction between societies and their environment has shaped the cultural landscapes across Europe. Specific farming systems have persisted for long periods, and their abandonment has led to far-reaching and rapid changes in patterns of land use and land cover. OBJECTIVE: Taking the example of the municipality of Limpach, located in the Swiss lowlands, we studied the dynamics of cultural landscape and related driving forces in a long-term perspective.

Ecological networks: Are they enough for connectivity conservation? A case study in the Barcelona Metropolitan Region (NE Spain)

Journal Articles & Books
Diciembre, 2012

This paper extends the debate on corridor effectiveness at regional planning scale, by exploring the contribution to landscape connectivity of a proposed ecological network and the remaining non-urbanized matrix in the Barcelona Metropolitan Region (BMR). Using the Ecological Connectivity Index, we evaluated the expected connectivity loss after the development of the approved urban plans in the region. Thus, we compared the baseline (present-day) and the projected (after planned urban development) connectivity scenarios for total, forest and agricultural habitats.

Surface temperature and hydrochemistry as indicators of land cover functions

Journal Articles & Books
Diciembre, 2012

This paper presents an integrated approach to landscape functioning assessment combining energy efficiency and hydrochemical balance studies. Energy balance is expressed by surface temperature while hydrochemical balance is illustrated by electric conductivity and selected hydrochemical parameters. Six model sub-watersheds with different land use situated in southern Bohemia were chosen to show the influence of landscape management on landscape functioning.

Geospatial technologies and digital geomorphological mapping: Concepts, issues and research

Journal Articles & Books
Diciembre, 2012

Geomorphological mapping plays an essential role in understanding Earth surface processes, geochronology, natural resources, natural hazards and landscape evolution. It involves the partitioning of the terrain into conceptual spatial entities based upon criteria that include morphology (form), genetics (process), composition and structure, chronology, environmental system associations (land cover, soils, ecology), as well as spatial topological relationships of surface features (landforms).
