Shocks to the system: community assembly of the oak savanna in a 40-year fire frequency experiment (2012, background): “The most frequently burned communities had the highest species richness, exhibited the most resource-conservative leaf traits, and spanned the greatest number of phylogenetic lineages but harbored more close relatives within those lineages than other communities.”
Woody exotic plant invasions and fire: reciprocal impacts and consequences for native ecosystems (2011, background): “Thus the presence of frequent, grass-fueled fires can limit or prevent the establishment of woody species and facilitate the continued existence of a grass-dominated community ( Peterson and Reich 2007 ).”
Forest disturbance accelerates thermophilization of understory plant communities (2015, background): “Because intermediate levels of disturbances such as fire can produce greater variation in within-stand canopy closure (Peterson and Reich, 2008), we would expect intermediate disturbance severity to lead to high beta diversity (variation in species composition among vegetation plots within a forest ”
