The study aimed to develop a methodological framework to identify forest ecosystems affected by wildfires and evaluate their recovery chronologically. To do this remote sensing analysis, sites with burn scars were selected based on various criteria (fire severity, affected area, vegetation and soil type, slope, aspect, and one-time occurrence of wildfire in the last 23 years). Spectral vegetation indices (VIs) from satellite imagery were used to estimate burn severity and vegetation cover changes.

Work to date has shown that ATP2B2 (encoding PMCA2) is required for synaptic function and Purkinje-cell integrity in the cerebellum. A recent case series has linked ATP2B2 to a novel entity, characterized by neurodevelopmental and movement phenotypes, in only seven individuals.

Tremor Other Hyperkinet Mov (N Y)

Article Synopsis
- * A case study of a 24-year-old patient revealed they had a significant tremor disorder, including various types of tremors and additional symptoms like muscle stiffness and coordination issues, alongside some developmental delays and epilepsy.
- * This case underscores the importance of recognizing movement disorders in KBG syndrome, suggesting that genetic testing for pathogenic variants should be considered when diagnosing tremor-related conditions.
The Earth system has long lived with fires, but the impact of climate change on fire regimes has led to extreme wildfire events with higher intensity and faster spread. This has effects on ecosystems and resources, air pollution, and, ultimately, human societies. Facing these compounding challenges require interdisciplinary solutions and collaborations.

However, simulating NH pollution presents unique challenges due to the inherent instability of NH in natural environment. This study modified the widely-used Soil and Water Assessment Tool (SWAT) model to simulate non-point source (NPS) NH processes, specifically incorporating the simulation of land-to-water NH delivery.
