Phosphorus (P) is a limiting nutrient for terrestrial biological productivity that commonly plays
a key role in net carbon uptake in terrestrial ecosystems (Tiessen et al. 1984, Roberts et al …

Volcanic eruptions affect land and humans globally. When a volcano erupts, tons of volcanic
ash materials are ejected to the atmosphere and deposited on land. The hazard posed by …

The availability or lack of nutrients shapes ecosystems in fundamental ways. From forest
productivity to soil fertility, from the diversity of animals to the composition of microbial …

There is a pressing need to understand the consequences of human activities, such as land
transformations, on watershed ecosystem services. This is a challenging task because …

Biological, atmospheric, and geochemical processes interact to shape how element cycles
and nutrient losses develop within newly formed landscapes. We examined losses of …

Background and purpose Volcanic eruptions of pyroclastic tephra, including the ash-sized
fraction (< 2 mm; referred to as volcanic ash), have negative direct impacts on soil quality …

Forested soils in the tropics contain a large carbon pool that may respond to global
environmental changes such as climate warming and land-use change. A better …

Current models of ecosystem development hold that low nitrogen availability limits the
earliest stages of primary succession, but these models were developed from studies …

Sequential chemical extraction has been widely used to study soil phosphorus (P) dynamics
and inform nutrient management, but its efficacy for assigning P into biologically meaningful …

Invasive species pose major threats to the integrity and functioning of ecosystems. When
such species alter ecosystem processes, they have the potential to change the …
