How does the landscape context of occurrence data influence models of invasion risk? A comparison of independent datasets in Massachusetts, USA

Dezembro, 2014
Estados Unidos

The spatial distribution of non-native, invasive plants on the landscape is strongly influenced by human action. People introduce non-native species to new landscapes and regions (propagule pressure) as well as increase ecosystem invasibility through disturbance of native ecosystems. However, the relative importance of different landscape drivers of invasion may vary with landscape context (i.e., the types and amounts of surrounding land cover and land use). If so, data collected in one context may not be appropriate for predicting invasion risk across a broader landscape.

Ecological restoration planning based on connectivity in an urban area

Journal Articles & Books
Dezembro, 2012

In urban areas, the competition between land development and ecological conservation is intense. To mitigate the negative effects of urbanization, we developed a methodology to plan a spatially explicit conservation network based on widely available remotely sensed data and other auxiliary data. First, as an area of strategic significance for the conservation of regional flora and fauna and for maintaining high environmental quality to promote human well-being, the remaining natural and semi-natural areas were identified as ecologically primary areas.

Bielorrússia

The main tasks of the reclaimed and soil science have been formulated. It was noted that the radical and final reorientiring of the reclaimed and soil science as a whole in the country is necessary to working out the science methodology of support and effective functioning of the acting reclaimed complexes and systems. It is necessary to expand researches on microbiology, biochemistry and biophysics of agricultural lands with the purpose of the long-term strategy of the fertility, productivity and land immunity improvement.

Impacts of Land Use Characterization in Modeling Hydrology and Sediments for the Luxapallila Creek Watershed, Alabama and Mississippi

Journal Articles & Books
Dezembro, 2008

The Hydrological Simulation Program - Fortran (HSPF), interfaced with the Better Assessment Science Integrating Point and Nonpoint (BASINS), was used to evaluate the impact of land use (as characterized by different land use/land cover (LU/LC) datasets) on hydrology and sediment components of the Luxapallila Creek watershed. The 1,770 km 2 watershed is located in Alabama and Mississippi. Simulation of the watershed processes were tested at the hillslope and at the watershed outlet for the period between 1985 and 2003.

Identifying plant species and communities across environmental gradients in the Western Himalayas: Method development and conservation use

Journal Articles & Books
Dezembro, 2013

Phytosociological attributes of plant species and associated environmental factors were measured in order to identify the environmental gradients of major plant communities in the Naran Valley, Himalayas. The valley occupies a distinctive geographical setting on the edge of the Western Himalaya near the Hindukush range and supports a high biodiversity; pastoralism is the main land use. There have been no previous quantitative ecological studies in this region.

Pastoralism, sustainability, and marketing. A review

Journal Articles & Books
Dezembro, 2014

Pastoralism is a highly traditional production system for livestock and livestock products. Under the surface of a seeming stability a variety of pressures of the modern time all seem to accumulate to put the sustainability of the pastoralist production system to the test. Population growth and growing demand for meat, put pressure on the natural resources used by pastoralists because the grazing lands that are saved from encroachment or conversion into arable lands, may be overexploited. Changing climatic conditions, such as frequent droughts, put even more pressure on the system.

Remote Sensing and GIS Based Landslide Susceptibility Assessment using Binary Logistic Regression Model: A Case Study in the Ganeshganga Watershed, Himalayas

Journal Articles & Books
Dezembro, 2013

A comprehensive Landslide Susceptibility Zonation (LSZ) map is sought for adopting any landslide preventive and mitigation measures. In the present study, LSZ map of landslide prone Ganeshganga watershed (known for Patalganga Landslide) has been generated using a binary logistic regression (BLR) model.
