On the uncertain intensity estimate of the 1859 Carrington storm

Journal of Space Weather and Space Climate
A study is made of the intensity of the Carrington magnetic storm of September 1859 as inferred from visual measurements of horizontal-component geomagnetic disturbance made at the Colaba observatory in India.

The influences of the galactic cosmic ray on the atmospheric ozone [PDF]

The relationship between the yearly variations of cosmic ray intensity and ozone in the atmosphere, and the ozone disturbance initiated by the Forbush decrease of 1965-1976 is analyzed.

Simulation of influence of disturbance on the release of endogenous phosphorus in sediment of HAOHE River of Nantong, China

MATEC Web of Conferences, 2016
There are less researches in the influence of disturbance of endogenous phosphorus release in sediment. The correlational analysis only takes the disturbance as one of the many factors in influencing the phosphorus release.

Effects of grazing disturbances on soil seed bank diversity in two vegetation types

Global Ecology and Conservation
Soil seed bank (SSB) play an essential role in the restoration and regeneration of plant communities. Grazing is a common disturbance factor that exerts an important effect on the diversity and composition of the SSB community in forests.

Interacting contemporary and legacy disturbances affect management of floodplain forest vegetation

Basic and Applied Ecology
Disturbance is a strong driver of forest ecosystem species composition. Understanding how current management interacts with disturbance is critical for implementing effective strategies to promote native species.
