The grasslands of North America are threatened by woody encroachment. Restoring
historical fire regimes has been used to manage brush encroachment. However, fire …

North American grasslands have experienced increased relative abundance of shrubs and
trees over the last 150 yr. Alterations in herbivore composition, abundance, and grazing …

In restoration ecology, the transition from desired to degraded state is based solely on the
composition of the aboveground plant community, whereas belowground propagules are …

Hysteresis is a fundamental characteristic of alternative stable state theory, yet evidence of
hysteresis is rare. In mesic grasslands, fire frequency regulates transition from grass‐to …

Determining how ecological communities will respond to global environmental change
remains a challenging research problem. Recent meta‐analyses concluded that most …

Ecosystem succession and biodiversity change associated with grassland fires are crucial
for the patterns and dynamics of ecosystem functioning and services. The reactions to fire by …

Regime shifts are difficult‐to‐reverse transitions that occur when an ecosystem reorganizes
around a new set of self‐reinforcing feedbacks. Regime shifts are predicted to occur when …
