Forest Biomes. Read all about forests, including forest ecology, carbon uptake, and how human activities are affecting forests.
  1. The 2021 Dixie Fire burned over nearly 1 million acres in California and cost $637 million to suppress, making it the largest and most expensive wildfire to contain in state history. Fire history largely determined how severely the wildfire burned, and low-severity fire treatments had the largest impact on reducing the worst effects of the fire, according to a research team.
  2. A study reveals an unprecedented change in the fire regime in Europe which is related to climate change. The affected areas are in Southern, Central and Northern Europe but this historical change in Europe's fire regime is more intense in the Mediterranean area.
  3. Researchers examined 21st century changes in ocean-surface temperature, salinity, and density, across mangrove forests worldwide. Their study suggests that changes in surface-ocean density may impact the dispersal patterns of widely distributed mangroves species, and more likely so in the Indo-West Pacific region, the primary hotspot of mangrove diversity.
  4. New research highlights how the risk of wildfire is rising globally due to climate change -- but also, how human actions and policies can play a critical role in regulating regional impacts. The study shows that anthropogenic climate change is a 'push' factor that enhances the risk of wildfires globally.
  5. A dramatic outbreak of kelp-eating sea urchins along the Central Coast of California in 2014, leading to a significant reduction in the region's kelp forests, was driven primarily by the emergence of sea urchins from their hiding places rather than an increase in the urchin population. In subsequent years, sea urchin movements enabled kelp forest recovery at sites that had been denuded 'urchin barrens.' Those are among the key findings of a long-term study of sea urchins and kelp forest dynamics in Monterey Bay.
