Seed Bank and Ashfalls: The Ecological Resetting Effect of the Recent Tajogaite Volcano Eruption in the Canary Pine Forest (La Palma, Spain) Open
Question Tephra deposition is one of the most critical sudden alterations caused by volcanic eruptions in ecosystems. Tephra accumulation on the ground decreases with distance from the crater. The effect of ash deposition on the seed bank …

Volcanic eruption and wildfires as compounding drivers of first-year seedling establishment in Canary pine Open
On the island of La Palma, located in the Canary Islands, Spain, the Canary pine forest is largely unmanaged and depends on natural regeneration for sustainable population dynamics. Canary pine (Pinus canariensis C.Sm. ex DC.) has been con…

Spring Water pH in Forest Catchments Is Modified through Fluctuating Discharge under Climate Change Open
Over the course of industrialization in the 20th century, vast emissions of air pollutants have occurred. The exhaust gasses contain sulfur and nitrogen oxides, which are converted to sulfuric acid and nitric acid in the atmosphere. This c…

Impacts of Forest Fire on Understory Species Diversity in Canary Pine Ecosystems on the Island of La Palma Open
Forest fires are drivers of spatial patterns and temporal dynamics of vegetation and biodiversity. On the Canary Islands, large areas of pine forest exist, dominated by the endemic Canary Island pine, Pinus canariensis C. Sm. These mostly …

Assessing the Potential Replacement of Laurel Forest by a Novel Ecosystem in the Steep Terrain of an Oceanic Island Open
Biological invasions are a major global threat to biodiversity and often affect ecosystem services negatively. They are particularly problematic on oceanic islands where there are many narrow-ranged endemic species, and the biota may be ve…
