The Impact

High-frequency disturbance forest ecosystems undergo complex and frequent changes at various spatiotemporal scales owing to natural and anthropogenic factors. Effectively capturing the characteristics of these spatiotemporal changes from satellite image time series is a powerful and practical means for determining their causes and predicting their trends. Herein, we combined the spatiotemporal cube and vegetation indices to develop the improved spatiotemporal cube (IST-cube) model. We used this to acquire the spatiotemporal dynamics of forest ecosystems from 1987 to 2020 in the study area and then classified it into four spatiotemporal scales. The results showed that the cube-core only exists in the increasing IST-cubes, which are distributed in residential areas and forests. The length of the IST-cube implies the duration of triggers. Human activities result in long-term small-scope IST-cubes, and the impact in the vicinity of residential areas is increasing while there is no change within. Meteorological disasters cause short-term, large scope, and irregular impacts. Land use type change causes short-term small scope IST-cubes and a regular impact. Overall, we report the robustness and strength of the IST-cube model in capturing spatiotemporal changes in forest ecosystems, providing a novel method to examine complex changes in forest ecosystems via remote sensing.

Forest fires constitute widespread and potentially destructive disturbances in forest ecosystems, particularly negative impact on soil mycorrhizal fungi which are major players of the belowground plant. This study investigated the short-term effects of wildfire on fungal communities in Left-Bank Ukraine with special emphasis on mycorrhizal fungi. During the fourteen months after autumn wildfire, fruiting bodies found in the plots were identified, and their mycological richness, diversity and production in both burned and unburnt areas were measured. Total fungal diversity decreased in burned plots, where fungal richness and diversity of mycorrhizal species were significantly lower. Our results also confirmed the data on a rather destructive influence of post-fire forest management on fungal diversity. Only three mycorrhizal fungi associated with Pinus sylvestris L. were common to both sites while pyrophilic species were in close association with burned sites. 3 Figs., 1 Table, 31 Refs.
