Amazon fire regimes under climate change scenarios

Subjects: Ecology and Evolutionary Biology, Forest Biology, Forest Sciences, Life Sciences, Systems Biology, Terrestrial and Aquatic Ecology
Fire is one of the most important disturbances of the earth-system, shaping the biodiversity of ecosystems and particularly forests. Climatic change and other anthropogenic drivers such as deforestation and land use change could produce abrupt changes in fire regimes, potentially triggering transition from forests to savannah or grasslands ecosystems with large accompanying biodiversity losses.

Do forest fuel reduction treatments confer resistance to beetle infestation and drought mortality?

Climate change is amplifying the frequency and severity of droughts and wildfires in many forests. In the western U.S., fuels reduction treatments, both mechanical and prescribed fire, are widely used to increase resilience to wildfire but their effect on resistance to drought and beetle mortality is not as well understood. We followed more than 10,000 mapped and tagged trees in a mixed-conifer [...]
Predicting tropical tree mortality with leaf spectroscopy

Do tropical trees close to death have a distinct leaf spectral signature? Tree mortality rates have been increasing in tropical forests globally which is reducing the global carbon sink. Upcoming hyperspectral satellites could be used to predict regions close to experiencing extensive tree mortality during periods of stress like drought. Here we show how imminent tropical tree mortality in [...]
Optimising occupancy models and detection probability for conservation monitoring in a forest-dwelling small mammal

The ability to determine the survey effort required to detect species presence is critical for the conservation of populations in order to monitor changes in distribution or abundance, a challenge for rare and elusive species. While designing an effective population survey may be of concern to scientists, it may also be a legal requirement for protected species. We analysed how spatial and [...]
