Maple Sugar Bush Management and Biodiversity Conservation in Eastern Ontario, Canada
… areas. The production of maple syrup on sugar bushes has already been demonstrated to be economically, socially, and in some aspects ecologically sustainable. This study seeks to determine how the operation of sugar bushes might also contribute to ecological sustainability through the …

Assessment of carbon stock and selected soil fertility indicators in a bush encroached savanna at Erichsfelde farm, Namibia
… nutrient deficiency due to the fact that savanna bushes have less biomass that returns low nutrients to the soil. It can be concluded that despite the known ecological importance of invader bushes, they do not sequester significant amounts of carbon nor do they positively contribute to soil …

Analysis of Viewshed Accuracy with Variable Resolution LIDAR Digital Surface Models and Photogrammetrically-Derived Digital Elevation Models
… and targets that were obscured by trees or bushes. A logistic regression was performed between that distance and the visibility of the target to determine the extent to which a greater amount of vegetation along the line-of-sight impacted the target's visibility.

Learning Generative Models Using Structured Latent Variables
… For example, detecting a dog hidden in the bushes by looking at its exposed tail is a task that is not yet solved by discriminative neural networks. Another class of challenging tasks is one-shot learning, where only one training example for a new concept is available to the model for …
