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

open access: yesPLoS 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]

open access: yesFrontiers 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

Effect of ground slope on extent and intensity of soil disturbance from skidder logging (Case study: Nav-e Asalem forest, Gilan province) [PDF]

open access: yesتحقیقات جنگل و صنوبر ایران, 2017
Protection of forest soil is one of key factors in having sustainable productive forests. In this research extent and intensity of soil disturbance due to extraction of logs of felled trees (20.5 m3/ha) were studied in Nav-e Asalem forest in Gilan ...

Intensification of disturbance destabilizes productivity through effects on dominant species

open access: yesEcological Indicators, 2022
Disturbances, including anthropogenic disturbances, are integral to the maintenance of grassland ecosystems. Most research on anthropogenic disturbances focuses on the effects of intensification, yet cessation of disturbance can have equally important ...

Analysis of Cyperus esculentus–Soil Dynamic Behavior during Rotary Tillage Based on Discrete Element Method

open access: yesAgriculture, 2023
Considering the problems of low soil fragmentation rates, high working resistance, and high energy consumption in the harvesting process of Cyperus esculentus in China, a method of Cyperus esculentus harvesting based on counter-rotation digging is ...

Effects of temporal variability of disturbance on the succession in marine fouling communities in northern-central Chile [PDF]

open access: yes, 2007
We investigated the effects of temporal variability in a disturbance regime on fouling communities at two study sites in a northern-central Chilean bay. Fouling assemblages grown on artificial settlement substrata were disturbed by mechanical removal of ...

Physical Characteristics of Section Coal and Rock Pillars Under Roof Shock Disturbances From Goaf

open access: yesFrontiers in Physics, 2020
The stability of a rock strata structure is closely related to its response physical characteristics under external shock disturbance. The roof shock disturbance from goaf is usually one of the important factors that cause coal and rock pillar ...

Foreword [PDF]

open access: yes, 1940
While several studies have explored how short-term ecological responses to disturbance vary among ecosystems, experimental studies of how contrasting ecosystems recover from disturbance in the longer term are few.

Temporal variance of disturbance did not affect diversity and structure of a marine fouling community in north-eastern New Zealand [PDF]

open access: yes, 2007
Natural heterogeneity in ecological parameters, like population abundance, is more widely recognized and investigated than variability in the processes that control these parameters.
