Effect of stability on mixing in open canopies [PDF]
Agricultural and Forest Meteorology, 2005 In open canopies, the within-canopy flux from the ground surface and understory can account for a significant fraction of the total flux above the canopy. This study incorporates the important influence of within-canopy stability on turbulent mixing and subcanopy fluxes into a first-order closure scheme.

Survival and Growth of Brazil-Nut Seedlings in Tree-Fall Gaps and Forest Understory
Floresta e Ambiente, 2020 This study aimed to evaluate the influence of canopy openness on the survival and growth of Bertholletia excelsa seedlings, through experimental plantings in tree-fall gaps and forest understory in Madre de Dios, Peru.

Frontiers in Ecology and Evolution, 2022 Climate warming is forecasted to cause extinctions, but populations could theoretically avoid extinction in a rapidly changing environment via adaptive evolution (i.e., evolutionary rescue), precluding the need for intervention.

Factors affecting the abundance of leaf-litter arthropods in unburned and thrice-burned seasonally-dry Amazonian forests. [PDF]
PLoS ONE, 2010 Fire is frequently used as a land management tool for cattle ranching and annual crops in the Amazon. However, these maintenance fires often escape into surrounding forests, with potentially severe impacts for forest biodiversity.

Sociobiology, 2017 Ant-garden ants have a strong relationship with epiphytes that need light to grow, for these reason, it has been previously documented in forest gaps. Moreover, larger gaps have more available area for nesting and habitats for use as forage.

CONSTRUCTION AND PRACTICAL APPLICATION OF A CANOPY OPENER DEVICE [PDF]
Engenharia Agrícola, 2016 ABSTRACT: Accurate application of pesticides is difficult for crops with dense leaves, such as soybean crops. To improve spray deposits on the lower leaves of soybean plants, the aim of this study is to build a canopy opener (CO) from a previously developed prototype and to assess its practical application and efficiency on soybean crops.

Agronomy, 2023 Open-canopy pesticide application technology is not affected by the canopy structure and can substantially increase droplet penetration and deposition in the middle and lower rice canopy. However, the optimal working position of the canopy opener is difficult to determine.

The nocturnal water cycle in an open‐canopy forest [PDF]
Journal of Geophysical Research: Atmospheres, 2013 The movement of moisture into, out‐of, and within forest ecosystems is modulated by feedbacks that stem from processes which couple plants, soil, and the atmosphere. While an understanding of these processes has been gleaned from Eddy Covariance techniques, the reliability of the method suffers at night because of weak turbulence.
