DOI: 10.1002/asjc.1802
Abstract: This paper focuses on a novel feedback linearization control (FLC) law based on a self‐learning disturbance observer (SLDO) to counteract mismatched uncertainties. The FLC based on BNDO (FLC‐BNDO) demonstrates robust control performance only against mismatched… read more here.

DOI: 10.1002/asjc.2138
Abstract: In this paper, a robust H∞ control problem is considered for an uncertain singular system. An active disturbance rejection method called equivalent input disturbance (EID) is used to reduce the influence of exogenous disturbances and… read more here.

DOI: 10.1002/ece3.10049
Abstract: Abstract Combined effects of disturbance and productivity on ecological diversity have been considered for decades as the dynamic equilibrium model (DEM) but are rarely tested together. Instead, most studies focus on either the intermediate disturbance… read more here.

DOI: 10.1002/ece3.3395
Abstract: Abstract Land‐use and management are disturbance factors that have diverse effects on community composition and structure. In traditional rural grasslands, such as meadows and pastures, low‐intensity management is maintained to enhance biodiversity. Maintenance of road… read more here.

DOI: 10.1002/ece3.4276
Abstract: Abstract Global change is modifying species communities from local to landscape scales, with alterations in the abiotic and biotic determinants of geographic range limits causing species range shifts along both latitudinal and elevational gradients. An… read more here.

DOI: 10.1002/ece3.5106
Abstract: Abstract Seagrass are under great stress in the tropical coast of Asia, where Enhalus acoroides is frequently the dominant species with a large food web. Here, we investigate the question of the fine‐scale genetic structure… read more here.

DOI: 10.1002/ece3.6048
Abstract: Abstract Protected areas (PAs) in the tropics are vulnerable to human encroachment, and, despite formal protection, they do not fully mitigate anthropogenic threats to habitats and biodiversity. However, attempts to quantify the effectiveness of PAs… read more here.

DOI: 10.1002/ece3.7080
Abstract: Abstract In boreal landscapes, emphasis is currently placed on close‐to‐nature management strategies, which aim to maintain the biodiversity and ecosystem services related to old‐growth forests. The success of these strategies, however, depends on an accurate… read more here.

DOI: 10.1002/ece3.7568
Abstract: Abstract Forest ecosystems experience a myriad of natural and anthropogenic disturbances that shape ecological communities. Seedling emergence is a critical, preliminary stage in the recovery of forests post disturbance and is triggered by a series… read more here.

Disturbance and the (surprising?) role of ecosystem engineering in explaining spatial patterns of non‐native plant establishment

DOI: 10.1002/ece3.7915
Abstract: Abstract Different conceptions of disturbance differ in the degree to which they appeal to mechanisms that are general and equivalent, or species‐, functional group‐, or interaction‐specific. Some concepts of disturbance, for example, predict that soil… read more here.
