About this Research Topic
Forest Vegetation activity is driven by different combination modes of climate factors, displaying varying responses at different spatial and temporal scales. Furthermore, these combination modes are complicated by the different climate dynamics from daytime to nighttime, and on seasonal, inter-annual and decadal scales. The physiological and ecological processes of vegetation growth have to adapt to these combination modes, causing greatly varying responses of vegetation activity to climate change globally. This range of vegetation responses includes processes such as photosynthesis, flux measurements, remotely sensed greenness, growth, and phenology, among others. These differing responses impact the characteristics of ecosystem structure, trait, process and function, including community structure, phenology, geochemical and geophysical cycling.
Previous research has found varying responses or sensitivities of vegetation activity to different climate factors on different scales. Such responses or sensitivities may also be related to geographical factors, such as elevation and terrain aspect. However, the overall view of the varying responses and the underlying mechanisms are still unclear because of complex interacted driving effects between climate, topography and other environmental factors. The goal of this Research Topic is to identify the interacted effects of environmental factors and their relative contributions, by focusing particularly on Northern hemisphere forests. We especially hope to clarify the effect of topographic factors on the environmental factors in order to better understand the underlying mechanisms of varying responses of vegetation activity to climate change. Remote sensing, meta-analysis, model simulation and flux research can detect the varying responses and the underlying interactions on a wide scale. These studies could macroscopically help to understand the vegetation ecosystem activity under climate change, and demonstrate the regional varying sensitivity of vegetation activity.
This Research Topic aims to gather innovative research articles indicating the varying responses of forest vegetation ecosystems to climate change and understanding the mechanisms leading to the variation. We welcome studies based on experiments, ground observation, meta-analysis, remote sensing and modelling approaches, focusing on the following topics:
• Mechanistic understanding of vegetation activity in response to climate change and extreme events at different scales (e.g. community, landscape, region, and the globe)
• Phenology studies over local areas or the entire Northern Hemisphere. Cultivated vegetation response to natural climate change.
• Analyses on carbon cycles across natural vegetation ecosystems (single or mixed, such as forest, grassland, shrubs, tundra, etc).
• Greening and browning of forest dynamics under climate change.
• Biomass development across different time-scales (such as daytime-nighttime, seasonal, inter-annual).
• Diverse sensitivities to climatic and other indicators among different period.
• Ecosystem responses with environmental disturbances (extreme events, pollutions in atmosphere and light, et al.).
• Effect of topographic factors on responses of vegetation activity to climate change.
• Ecosystem modelling and predicting future vegetation responses to climate change.
