The use of remote sensing to estimate forest structure has been largely tested but few researches have related such information about canopy closure in tropical forests in steep slope. This work aims to analyze the ...

In the Brazilian savanna (Cerrado of Brazil), fire suppression has transformed typical savanna formations (TS) into forested savanna (FS) due to the phenomenon of encroachment. Under encroachment, non-arboreal plants begin ...

The sustainable provision of pollination services in large regions of the Nearctic and Neotropics usually involves the coexistence of a rich assemblage of native bees and introduced bees in the same agroecosystem. This ...

The influence of the aspect ratio (building height/street canyon width) and the mean building height of cities on local energy fluxes and temperatures is studied by means of an Urban Canopy Model (UCM) coupled with a ...

The forests management and conservation are recently subjects discussed throughout the world, because they are directly correlation with the maintenance of environmental functions and services provided by natural environments. ...

Measuring leaf gas exchange from canopy leaves is fundamental for our understanding of photosynthesis and for a realistic representation of carbon uptake in vegetation models. Since canopy leaves are often difficult to ...

Vineyard cultural practices may influence amount of sugars, acids, phenolic compounds and antioxidant activity of grapes. Thus, the purpose of this study was to evaluate the effect of different shoot topping levels on the ...
