Collapse, reorganization, and regime identity: breaking down past management paradigms in a forest-grassland ecotone

Ecology and Society, 2021
The identity of an ecological regime is central to modern resilience theory and our understanding of how systems collapse and reorganize following disturbance.

Does degradation from selective logging and illegal activities differently impact forest resources? A case study in Ghana [PDF]

, 2016
Degradation, a reduction of the ecosystem’s capacity to supply goods and services, is widespread in tropical forests and mainly caused by human disturbance.

TreeSpider: In‐Canopy Exploration With Tether‐Based Aerial Modular Arms

Advanced Robotics Research, EarlyView.
A tethered drone with perching arms and a 360° ring enables unprecedented maneuverability within dense forest canopies. By dynamically adjusting tether length and decoupling pitch from the frame, it navigates between branches, senses multiple trees, and interacts physically with foliage.

Biological Individuality Is Not Necessarily an Intrinsic Property

Philosophy, Theory, and Practice in Biology
A significant and longstanding debate in philosophy of biology has centered around biological individuality. Although there have been numerous attempts to articulate a plausible and unifying view of what makes something a biological individual, the ...

Integrating Ecological and Engineering Concepts of Resilience in Microbial Communities [PDF]

, 2015
Many definitions of resilience have been proffered for natural and engineered ecosystems, but a conceptual consensus on resilience in microbial communities is still lacking. We argue that the disconnect largely results from the wide variance in microbial

Multimodal Locomotion in Insect‐Inspired Microrobots: A Review of Strategies for Aerial, Surface, Aquatic, and Interfacial Motion

Advanced Robotics Research, EarlyView.
This review identifies key design considerations for insect‐inspired microrobots capable of multimodal locomotion. To draw inspiration, biological and robotic strategies for moving in air, on water surfaces, and underwater are examined, along with approaches for crossing the air–water interface.

Does the ecological concept of disturbance have utility in urban social–ecological–technological systems?

Ecosystem Health and Sustainability, 2017
The ecological concept of disturbance has scarcely been applied in urban systems except in the erroneous but commonplace assumption that urbanization itself is a disturbance and cities are therefore perennially disturbed systems.

Physical Disturbance Reduces Cyanobacterial Relative Abundance and Substrate Metabolism Potential of Biological Soil Crusts on a Gold Mine Tailing of Central China

Frontiers in Microbiology, 2022
As the critical ecological engineers, biological soil crusts (biocrusts) are considered to play essential roles in improving substrate conditions during ecological rehabilitation processes. Physical disturbance, however, often leads to the degradation of
