Diversity–disturbance relationships: frequency and intensity interact [PDF]

Biology Letters, 2012
An influential ecological theory, the intermediate disturbance hypothesis (IDH), predicts that intermediate levels of disturbance will maximize species diversity. Empirical studies, however, have described a wide variety of diversity–disturbance relationships (DDRs).

Effects of disturbance intensity and frequency on bacterial community composition and function. [PDF]

PLoS ONE, 2012
Disturbances influence community structure and ecosystem functioning. Bacteria are key players in ecosystems and it is therefore crucial to understand the effect of disturbances on bacterial communities and how they respond to them, both compositionally ...

Increased vegetation disturbance intensity reduces soil nutrients while enhancing microbial network interactions [PDF]

Frontiers in Microbiology
Introduction and methodsVegetation disturbance intensity serves as a critical determinant of changes in soil nutrients and microbial communities. Karst ecosystems are highly fragile, and vegetation degradation has contributed to severe desertification in

Itch, Scratching, and Sleep Mediate the Association between Disease Severity and Quality of Life in Pruritic Dermatoses: A Cross-Sectional Study [PDF]

Dermatology and Therapy
Introduction Chronic inflammatory skin conditions significantly impact the quality of life (QoL) of those affected. Itch is a cardinal symptom in many of these conditions, contributing decisively to the burden of disease.

Disturbance intensity shapes universal and context-dependent functional traits in anaerobic microbiomes [PDF]

Environmental Science and Ecotechnology
Trait-based frameworks, notably Grime's competitor–stress-tolerant–ruderal theory, offer a powerful lens for predicting how environmental fluctuations govern community structure.

Local Resource Availability and Subsidy Flow Mediate the Effects of Disturbances in Meta‐Ecosystems [PDF]

Ecology and Evolution
Disturbances can negatively affect multiple levels of biological organization. With human activities increasing the intensity of disturbance regimes, we need to understand when and where adverse effects of disturbance occur.

A nonlinear disturbance observer for robotic manipulators [PDF]

, 2000
A new nonlinear disturbance observer (NDO) for robotic manipulators is derived in this paper. The global exponential stability of the proposed disturbance observer (DO) is guaranteed by selecting design parameters, which depend on the maximum velocity ...

Spatiotemporal Coupling Relationship Between Plateau Pika Disturbance and Alpine Meadow Degradation

Shuitu baochi tongbao, 2023
[Objective] Plateau pika (Ochotona curzoniae) is a key species in the alpine meadow ecosystem of the Qinghai-Xizang Plateau. The coupling relationship between pika activity and meadow degradation was analyzed in order to further improve the observation ...

Effect of Plateau Pika Disturbance on Plant Aboveground Biomass of Alpine Meadows at Two Different Scales

Plants, 2022
Disturbance by small burrowing herbivores often has an impact on plant aboveground biomass of grassland because it makes grasslands into a mosaic of discrete vegetated surfaces and bare soil patches.
