Article history: Received 15 February 2005 Received in revised form 9 April 2005 Accepted 12 April 2006 This study demonstrated prediction of breeding success of Black-tailed Gulls in relation to the selected environmental factors through evaluation of relative importance in determining breeding success. The data were obtained from the 258 selected and 120 non-selected sites for breeding of the...

introduction: soil organic matter is influenced strongly by vegetation cover and management, therefore it is proposed as the main indicator of soil quality and health. the changes in soil organic matter status occur much more rapidly in the labile pools than in organic c. thus, labile pools can be used as early indicators of changes in total organic matter that will become more obvious in the l...

Validating model simulations of vegetation-climate feedback needs information not only on changes in past vegetation types as reconstructed by palynologists, but also on other proxies such as vegetation cover. We present here a quantitative regional vegetation cover reconstruction for North China during the Holocene. The reconstruction was based on 15 high-quality lake sediment profiles selecte...

The objective of this study was to assess the relationship betweenvegetation, landform and physicochemical properties of soil. At the first terrainmap unit were provided using the landsat thematic mapper (TM) satellite images,aerial photograph, topographical and geology map. Field sampling was done in therepresentative area using plot sampling. 104 plots 100 m2 were sampled in eachplot landform...

Multi-temporal Landsat coverages of the entire Australian continent have been assembled under the Australian Greenhouse Office (AGO) National Carbon Accounting System (NCAS) Land Cover Change Program. The major purpose of this program was the production of spatially detailed classifications of the extent and change in area of forest cover for Australia since 1972 for input to carbon modelling. ...

Inland saline wetlands are complex systems undergoing continuous changes in moisture and salinity and are especially vulnerable to human pressures. Remote sensing is helpful to identify vegetation change in semi-arid wetlands and to assess wetland degradation. Remote sensing-based monitoring requires identification of the spectral characteristics of soils and vegetation and their correspondence...

this paper aims to detect occurred changes in vegetation cover of forested helen protected area using extracted ndvis from bi-temporal multispectral images of landsat tm. to do so, at first forest areas with low and moderate density cover were identified and separated on land use map. then preprocessing applications including radiometric corrections were done on both 1990 and 2009 images. also ...
