Grasses as invasive alien plants in South Africa (2004, background): “As in the case of cheat grass, these herbaceous plants out-compete and prevent the establishment of seedlings of native woody plants.(36) Biological ‘soil crusts’ inhibit cheat grass establishment(37), but both livestock and fire reduce cryptogram cover on friable soil surfaces,(29) facilitating inv”
Alternative states and positive feedbacks in restoration ecology. (2004, background): “These constraints can operate at multiple scales, and the dynamics at one scale can affect those at another [ 39 ,46].”
The impact of feral horses on grassland bird communities in Argentina (2004, background): “Grazing produces changes in the composition of plant communities, modifies the horizontal structure of the vegetation creating open shrublands and increasing the percentage of bare ground, which in turn causes changes in the associated wildlife (Holechek, Pieper & Herbel, 1989; Hobbs, 2001).”
Confounding factors in the detection of species responses to habitat fragmentation (2005, background): “For instance, trampling by cattle compacts soil structure, reducing the regeneration ability of native tree species that are already struggling with competition from introduced weeds (Hobbs, 2001).”
Multiple Effects of Introduced Mammalian Herbivores in a Temperate Forest (2002, background): “Furthermore, altered community structure resulting from introduced mammalian herbivores is in some cases accompanied by increased richness of exotic plant species (Mack 1989; Hobbs and Huenneke 1992; Hobbs 2001; Chaneton et al. 2002).”
Is Pinus radiata invading the native vegetation in central Chile? Demographic responses in a fragmented forest (2005, background): “The invasibility of fragments is expected to increase with the intensity of disturbances and when the forest canopy is reduced (Richardson and Brown 1986; Laurence 1997; Viana et al. 1997; Hobbs 2001), thus promoting microclimatic/physical changes inside fragments and leading to an increase of safe ”
Island theory, matrix effects and species richness patterns in habitat fragments (2002, background): “…recognition that the matrix in fragmented landscapes can potentially influence 2002 Blackwell Science Ltd/CNRS species abundance or composition in the embedded patches (Holt 1997; Gascon & Lovejoy 1998; Ås 1999; Harrison 1999; Hobbs 2001; but see Anderson & Wait 2001; Davies et al. 2001).”
Assessing the relative importance of disturbance, herbivory, diversity, and propagule pressure in exotic plant invasion (2009, background): “Although the increased abundance of exotic plants due to a reduction in generalist enemy regulation is not well documented in forest systems, introduced generalist grazers have been shown to facilitate the invasion of some exotic grasses (Mack 1981, O’Connor 1991, Hobbs 2001, Parker et al. 2006).”
The Effects of Invasive Ants on Prospective Ant Mutualists (2004, background): “…South America, CA = Central America, ME = Mediterranean, CAR = Caribbean. concern is that invasive ants readily invade disturbed habitats such as forest edges or agricultural fields, yet researchers rarely distinguish the effects of invasion and disturbance (Butz Huryn 1997; Hobbs 2001; Ness 2004).”
Exotic Herbivores as Drivers of Plant Invasion and Switch to Ecosystem Alternative States (2002, background): “Rabbits and hares were introduced as recently as the nineteenth century into Chile and southwestern Australia, and can maintain very large populations because they lack natural enemies (Jaksic and Soriger 1981; see also references in Hobbs 2001).”
Landscape modification and habitat fragmentation: a synthesis (2007, background): “For example, domestic livestock grazing can simplify vegetation structure and exacerbate the replacement of native species by introduced species (Hobbs, 2001), as well as reduce regeneration rates of native woody vegetation (Spooner et al.”
Seed dispersal and recruitment limitation are barriers to native recolonization of old-fields in western Australia (2007, background): “, that are dominant in the landscape (Hobbs 2001) and are likely to be represented in the old-field soil seed banks (Grime 1979).”
Biotic interactions and plant invasions. (2006, methodology): “The novel weapons (Callaway & Ridenhour 2004), new associations (Hokkanen & Pimentel 1989), and recent extensions of the biotic resistance (Parker & Hay 2005) hypotheses propose that such biases arise from plants sharing a longer coevolutionary history with species in their native range than in…”
The role of land-use history in major invasions by woody plant species in the northeastern North American landscape (2009, background): “forests—without comparing multiple land-use patterns across heterogeneous landscapes (Bartuszevige et al. 2006; Hobbs 2001; Kulmatiski et al. 2006; Lundgren et al. 2004; Meiners et al. 2002; Pascarella et al. 2000).”
Landscape matrix and species traits mediate responses of Neotropical resident birds to forest fragmentation in Jamaica (2010, background): “Third, anthropogenic land use disturbance, such as hunting, logging, noise, and burning in remaining habitat patches, may vary as a function of matrix type (i.e., disturbance hypothesis) (Hobbs 2001, Laurance and Cochrane 2001, Peres 2001).”
