Influência de borda sobre vegetação e microclima no cerrado paulista
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Ecologia e Recursos Naturais - PPGERN, 2011-02-04)
There is much variation in patterns of edge influence (EI) within a region due to factors such as vegetation structure, adjacent land use, orientation and edge contrast, and assessment of this variation is important for ...
Spatial heterogeneity of leaf wetness duration in apple trees and its influence on performance of a warning system for sooty blotch and flyspeck
(AMER PHYTOPATHOLOGICAL SOC, 2008)
To determine the effect of sensor placement on the performance of a disease-warning system for sooty blotch and flyspeck (SBFS), we measured leaf wetness duration (LWD) at 12 canopy positions in apple trees, then simulated ...
Effects of canopy gaps on the microclimate, seedling establishment, growth and survival in a Nothofagus betuloides dominated forest in Tierra del Fuego, Chile
(2013)
In Nothofagus betuloides dominated forests in Tierra del Fuego canopy gaps, regeneration
wave systems, partial mortality and blow-downs have been documented. The objective
was to analyse the effects of naturally created ...
Shade tree traits and microclimate modifications: Implications for pathogen management in biodiverse coffee agroforests
(Wiley Biotropica, New Jersey (Estados Unidos), 2021-04)
Diversified coffee agroforests modify microclimate conditions in comparison with monocultures, impacting the success of significant plant pathogens, such as Hemileia vastatrix, which causes coffee leaf rust (CLR). However, ...
Air temperature and canopy cover of impacted and conserved mangrove ecosystems: a study of a subtropical estuary in Brazil
(Coastal Education & Research Foundation, 2013-01-01)
The aim of this study was to analyze and compare the variation of air temperature between impacted and conserved mangrove areas by monitoring the microclimate and canopy cover of mangrove forests in the southern coast of ...
Spatial variability of leaf wetness duration in cotton, coffee and banana crop canopies
(São Paulo - Escola Superior de Agricultura Luiz de Queiroz, 2008)
Despite the importance of leaf wetness duration for plant disease epidemiology, there has been little attention paid to research on how its variability relates to different cropping situations. The objective of this study ...
Improving methods in gap ecology: Revisiting size and shape distributions using a model selection approach
(2013-05-01)
Questions: We assess gap size and shape distributions, two important descriptors of the forest disturbance regime, by asking: which statistical model best describes gap size distribution; can simple geometric forms adequately ...
