However, to facilitate completion of the final paper, I have recently switched to covering community ecology and ecosystem ecology before population ecology. As both ecology and evolution have to be covered in the same .
Chapter 1 describes the role of a visual guide within the context of soil risk ratings and soil-quality monitoring, and evaluates the effects of soil disturbance. Chapter 2 defines and describes the visual attributes that determine a soil-disturbance class. Chapters 3 through 6 describe each disturbance class, its criteria, and where it may occur.

practical control strategy that is Active Disturbance Rejection Control (ADRC) [10-14] to the EPAS system. The controller treats the discrepancy between the real EPAS system and its mathematical model as the generalized disturbance and actively estimates and rejects in real time, the disturbance
ON ACTIVE DISTURBANCE REJECTION CONTROL: STABILITY ANALYSIS AND APPLICATIONS IN DISTURBANCE DECOUPLING CONTROL QING ZHENG ABSTRACT One main contribution of this dissertation is to analyze the stability char-acteristics of extended state observer (ESO) and active disturbance rejection control (ADRC).
e recently developed active disturbance rejection con-trol (ADRC) is an e cient nonlinear digital control strategy which regards the unmodeled part and external disturbance as overall disturbance of the controlled system [ ] . e ADRC mainly consists of a tracking di erentiator (TD), an extended state observer (ESO), and a nonlinear state error
4. Active Disturbance Rejection Control . The active disturbance rejection control was proposed by Han [9][10][11][12]. It is designed to deal with systems having a large amount of uncertainty in both the internal dynamics and external disturbances. The particularity of the ADRC design is that the total disturbance is defined as
along the outer coast. Eighty-five percent of all pelicans observed to flush due to disturbance were roosting in natural landscapes. Disturbance occurred about once an hour at estuarine roosts versus once every four hours on artificial substrates. More than 90% of all disturbance incidents
the ecology of old-growth forests, forest successional dynamics, and disturbance processes. Our emphasis is on "coarse-filter" approaches to conservation (i.e., those that are concerned with entire ecosystems, their species and habitats, and the processes that support them) (Hunter 1990, Noss 1990). The recently published 2012 planning

For example, although the Forest Service already does some cost sharing, it could .
