1) Context: The resilience of the Earth's vegetation is changing heterogeneously, making it a challenge to unveil what causes these resilience changes. Understanding the driving forces of these changes can help us make informed management decisions to protect and restore ecosystems. Here, we address this gap by identifying the drivers that have caused the resilience of ecosystems to change during [...]

The stratified nature of tropical forest structure had been noted by early explorers, but until recent use of satellite-based LiDAR (GEDI, or Global Ecosystems Dynamics Investigation LiDAR), there has been no way to quantify stratification across all tropical forests. Understanding stratification is important because by some estimates, a majority of the world’s species inhabit tropical forest [...]

The Visayan warty pig is one of the endemic species of the Philippines that have been listed as "critically endangered." Conservation actions and efforts, such as health assessments, are being carried out to preserve the population. However, there is limited information about the normal hematological and biochemical profile of the species. The study presents reference intervals essential for [...]

Society is confronted by interconnected threats to ecological sustainability. Among these is the devastation of forests by destructive non-native pathogens and insects introduced through global trade, leading to the loss of critical ecosystem services and a global forest health crisis. We argue that the forest health crisis is a public good social dilemma and propose a response framework that [...]

The structure and role of fire in historical dry forests, ponderosa pine (Pinus ponderosa) and dry mixed-conifer forests, of the western USA, have been debated for 25 years, leaving two theories. The first, that these forests were relatively uniform, low in tree density and dominated by low- to moderate-severity fires was recently reviewed, including a critique of opposing evidence. The second, [...]

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, land use change, could produce potentially abrupt changes in fire regimes, triggering more profound transformations like the transition from forests to savannah or grasslands ecosystems. Large [...]

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 [...]

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 [...]

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 [...]
