1. Invasive species are present worldwide, yet predicting which invasive species will become problematic in which ecosystems remains an important ecological challenge. Floodplains are at particular risk for invasion, especially when subjected to anthropogenic disturbance. 2. We examined how components of flood regime, habitat quality and habitat configuration influenced the presence and abundan...

Abstract An analysis of snow cover measurement data in a number of physiographic regions and landscapes has shown that fields of snow cover characteristics exhibit statistical self-similarity property. This property is useful when, because of a sparse measurement network, the spatial variability of snow cover can be determined only for large enough basins. Small-scale variability of snow cover ...

The Northeastern region of India including Asom is one of the core area widely recognized as the centre of origin of rice germplasm. It is the largest region exceptionally rich in the rice genetic diversity. The physiographic and agroecological conditions vary in Asom very widely. The physical features, geographical isolation and historical realities have made the state an area of unique ethnic...

This study assessed a lidar-based, object-oriented (segmentation) approach to forest volume and aboveground biomass modeling. The study area in the Piedmont physiographic region of Virginia is composed of temperate coniferous, deciduous, and mixed stands. Segmentation objects, hierarchical in terms of area and ranging from 0.035 to 5.632 ha/object, were created using a lidar-derived canopy heig...
