Effects of Plateau Pika Disturbance on the Spatial Heterogeneity of Vegetation in Alpine Meadows

open access: yesFrontiers in Plant Science, 2021
Herbivory is one of the important factors that influence spatial heterogeneity of vegetation in grasslands. In this study, we focused on plateau pika (Ochotona curzoniae) to investigate the effects of the presence of small semi-fossorial herbivores and ...

Multi-cyclone analysis and machine learning model implications of cyclone effects on forests

open access: yesInternational Journal of Applied Earth Observations and Geoinformation, 2021
Past studies of cyclones (hurricanes, typhoons, tropical cyclones) disturbance showed that meteorological, topographical, and biological factors affect the patterns of forest disturbance intensity but left open the extent to which these findings were ...

Dynamics of the electrojet during intense magnetic disturbances [PDF]

open access: yesAnnales Geophysicae, 2018
Abstract. Hall current variations in different time sectors during six magnetic storms of the summer seasons in 2003 and 2005 are examined in detail: three storms in the day-night meridional sector and three storms in the dawn-dusk sector. We investigate the sequence of the phenomena, their structure, positions and the density of the polar (PE) and the

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 ...
