Non-indigenous grasses impede woody succession (2005, background): “The rate of woody encroachment into these environments has changed during the past century, increasing in some regions (Archer 1989; Van Auken 2000) and decreasing in others (del Moral 1985; Goldberg and Gross 1988; Inouye et al. 1994; Lawson et al. 1999).”
Alien plant invasions in tropical and sub-tropical savannas: patterns, processes and prospects (2010, background): “In this review we focus on invasions by alien (non-native) species (see Pyšek et al. 2004 for definition) and do not deal with bush encroachment, where native woody species encroach to form dense, often monodominant, stands (for details on this phenomenon in North America, see Van Auken 2000).”
Influence of shrub encroachment on aboveground net primary productivity and carbon and nitrogen pools in a mesic grassland (2004, background): “…encroachment within grasslands is a worldwide phenomenon, a better understanding of how shrub encroachment in grasslands alters C dynamics is important for quantifying and balancing the global C budget (Archer 1990; Scholes and Archer 1997; Van Auken 2000; Roques et al. 2001; Silva et al. 2001).”
Mechanisms of Plant Invasions of North American and European Grasslands (2011, background): “21:208–16 Van Auken OW.”
Shrub control and streamflow on rangelands: a process based viewpoint. (2002, background): “On the basis of several comprehensive reviews of the literature, we can conclude that the primary mechanism behind the increase in shrub cover has been a dramatic shift in patterns of herbivory and fire frequency during this time, although shifts in climate and CO2 concentrations have also been cite”
WOODY PLANT ESTABLISHMENT AND SPATIAL HETEROGENEITY IN GRASSLANDS (2003, background): “Woody plant proliferation in grasslands and savannas over the past century has been widely documented and its causes debated (Archer 1994, 2002, Archer et al. 1995, Van Auken 2000).”
Local versus landscape‐scale effects of savanna trees on grasses (2009, background): “Increases in tree or shrub abundances are thought to result from heavy or prolonged grazing, fire suppression and CO2 fertilization (van Vegten 1984; Archer, Schimel & Holland 1995; Scholes & Archer 1997; van Auken 2000; Roques, O’ Connor &Watkinson 2001; Morgan et al. 2007).”
The relative abundance of three plant functional types in temperate grasslands and shrublands of North and South America: effects of projected climate change (2002, background): “Whereas some studies suggest that the growth response of shrubs to increased CO2 is greater than that of grasses (Bassirirad et al., 1997; Polley et al., 1997), other investigators contend that CO2 increases do not account for incidences of shrub encroachment in arid and semiarid systems (Archer et ”
GRAZING SYSTEMS, ECOSYSTEM RESPONSES, AND GLOBAL CHANGE (2004, background): “Cited causes of woody encroachment include overgrazing of herbaceous cover that reduces competition for woody seedlings, fire suppression that enhances woody plant survival, atmospheric CO2 enrichment that favors C3 (woody) plant growth, and nitrogen pollution that favors woody encroachment (Figure ”
Alternative states and positive feedbacks in restoration ecology. (2004, background): “Climatic warming might be a chronic contributing factor to degradation of a system that is accelerated by other human activities [ 17 ].”
Quo vadis C4? An ecophysiological perspective on global change and the future of C4 plants (2004, background): “In the southwestern region of the North America, and in large areas of Africa, Australia, and South America, semiarid C4 grasslands have been converted to thornscrub by overgrazing from sheep and cattle (van Auken 2000).”
Toward a new generation of agricultural system data, models, and knowledge products: State of agricultural systems science (2017, background): “Expansion of woody species and increases in woody cover are widespread phenomena that under many but not all environmental conditions lead to the transition of early successional communities dominated by grasses and forbs to forests (Van Auken, 2000).”
