Habitat-mediated facilitation and counteracting ecosystem engineering interactively influence ecosystem responses to disturbance [PDF]

, 2011
Recovery of an ecosystem following disturbance can be severely hampered or even shift altogether when a point disturbance exceeds a certain spatial threshold. Such scale-dependent dynamics may be caused by preemptive competition, but may also result from

Survey to Evaluate Escape of Eucalyptus spp. Seedlings from Plantations in Southeastern USA

International Journal of Forestry Research, 2013
Interest in biomass-based energy in the southeastern Unites States has led to increased need for fast-growing tree species. Several Eucalyptus species exhibit characteristics that make them attractive in the bioenergy context. However, some of these also

Winter Climate Variability, De-Icing Salt and Streetside Tree Vitality

Frontiers in Ecology and Evolution, 2022
De-icing salts are applied to roads and walking surfaces to mitigate winter hazards resulting from ice, snow and freezing rain. The vitality of streetside trees, especially those growing in densely built urban areas, is compromised by repeated exposure ...

Disturbing forest disturbances

The Forestry Chronicle, 2005
The forest sector in Canada makes a significant contribution to the wealth of the nation. Many of our forest ecosystems, like the phoenix, need fire for rebirth and renewal. In contrast, other forests rely on a cool, wet disintegration driven by insects and their commensal fungi feeding on trees to effect this renewal.

Invasion of a Legume Ecosystem Engineer in a Cold Biome Alters Plant Biodiversity

Frontiers in Plant Science, 2018
Plant ecosystem engineers are widely used to combat land degradation. However, the ability of those plants to modulate limiting abiotic and biotic resources of other species can cause damage to ecosystems in which they become invasive.

A model comparison of fire return interval impacts on carbon and species dynamics in a southeastern U.S. pineland

Ecosphere, 2021
Ecosystem process models can be used to predict forest response to disturbances at a range of scales. Selection of the spatial class of model should depend on the scale of the research or management question, and model type should depend on the ecosystem

Embedded Model Control calls for disturbance modeling and rejection [PDF]

, 2012
Robust control design is mainly devoted to guaranteeing the closed-loop stability of a model-based control law in the presence of parametric uncertainties.

Disturbance Observers [PDF]

, 2020
Disturbance observer is an inner-loop output-feedback controller whose role is to reject external disturbances and to make the outer-loop baseline controller robust against plant's uncertainties. Therefore, the closed-loop system with the DOB approximates the nominal closed-loop by the baseline controller and the nominal plant model with no ...
