An increasing amount of Brazilian rainforest is being lost or degraded for various reasons, both anthropogenic and natural, leading to a loss biodiversity further global consequences. Especially in the state Mato Grosso, soy production large-scale cattle farms led extensive losses recent years. We used spectral mixture approach followed by decision tree classification based on more than 30 year...

This paper presents a novel approach – WireWarping for computing a flattened planar piece with length-preserved feature curves from a 3D piecewise linear surface patch. The property of lengthpreservation on feature curves is very important to industrial applications for controlling the shape and dimension of products fabricated from planar pieces. WireWarping simulates warping a given 3D surfac...

Dense aggregations of foundation species often mitigate environmental stresses for organisms living among them. Considerable work documents such benefits by comparing conditions inside versus outside these biogenic habitats. However, environmental gradients commonly arise across the extent of even single patches of habitat-forming species, including cases where stresses diverge between habitat ...

The objectives of our survey were to determine the most important environmental factors within buffer zones that influenced mollusc communities and evaluate ecological conservation value natural aquatic habitats (NAHs) support species. Analysis spatial structure catchments was based on a set landscape metrics. Land cover classes determined, radius 500 m from sampling point marked out. Mollusc s...

ABSTRACT Studies on birds and their habitats are usually conducted in natural areas (protected areas, forests, wetlands, etc.). In this study, the relationship between agricultural landscape diversity species of was investigated an zone surrounded by forested areas. Observations were carried out 60 sample grid squares. Presence/absence data for cultivated plants at each site recorded. The Shann...

The increasing rate of irreversible damages to natural habitats has reinforced the need for gathering biodiversity fundamental data to conservation. Priority setting is the most important step in protection programs. Solanaceae as the the one of important economic families of eudicots distributed throughout North and South America, Europe, Africa, Asia, Australia, and the South Pacific. Up to n...

Homalodisca vitripennis (Germar) and related species have caused millions of dollars in damage to southern California vineyards in recent years through the vectoring of Pierce's disease. However, the effects of surrounding vegetation on the dispersal and distribution of H. vitripennis are poorly understood. Therefore, the relationship between dispersal rates and patch quality was tested, as wel...

Adaptation to different habitat types across a patchy landscape may either arise independently in each patch or occur due to repeated colonization of each patch by the same specialized genotype. We tested whether open- and closed-canopy forms of Impatiens capensis, an herbaceous annual plant of eastern North America, have evolved repeatedly by comparing hierarchical measures of F(ST) estimated ...
