• Geographic structure, genetic diversity and source tracking of Spartina alterniflora (2007, background): “Considering the prevalence of hybrid cordgrass across much of San Francisco Bay (Ayres et al., 2004), it is possible that all individuals sampled from the embayment are hybrid progeny.”
• Hybridization, polyploidy and invasion: lessons from Spartina (Poaceae) (2009, background): “The fitness superiority (Ayres et al. 2007) and spread of the hybrids in California marshes (Ayres et al. 2004) is considered as a threat to the native S. foliosa populations (Ayres et al. 2003), and recent surveys have confirmed the great ecological impact of these hybrids is in the tidal marshes…”
• Benthic macrofaunal communities of three sites in San Francisco Bay invaded by hybrid Spartina, with comparison to uninvaded habitats (2005, background): “On the west coast of North America, there are 4 non-native species of Spartina (S. alterniflora, S. anglica, S. patens, and S. densiflora) and 1 native species, S. foliosa (Daehler & Strong 1996, Ayres et al. 2004).”
• Introduction and Spread of an Exotic Plant, Spartina alterniflora, Along Coastal Marshes of China (2017, background): “An increasing number of seedlings brought by tides, birds, or ballast could allow S.alterniflora to colonize more regions (Ayres et al. 2004).”
• Hybridization and the species problem in conservation (2015, background): “A striking example is the invasion of hybrid Spartina in estuaries, where vigorous recombinant genotypes alter patterns of sedimentation and water flow, with many cascading effects on native plants and animals (Ayres et al., 2004; Neira et al., 2005).”
• Hybridization dynamics of invasive cattail (Typhaceae) stands in the Western Great Lakes Region of North America: a molecular analysis (2010, background): “…& Baye 2003), has produced genotypes with heightened growth rates and fecundity and expanded environmental tolerances (Callaway & Josselyn 1992; Ayres, Strong & Baye 2003; Ayres et al. 2008), which now threaten to competitively exclude native S. foliosa (Daehler & Strong 1996; Ayres et al. 2004).”
• The austral cordgrass Spartina densiflora Brong.: its taxonomy, biogeography and natural history (2006, background): “In addition, S. densiflora has reappeared in areas where it was believed eradicated in San Francisco Bay (Smith et al., 2001; Ayres et al., 2004), and has colonized a number of new sites along the Pacific Coast of the USA.”
• The Invasive Species Challenge in Estuarine and Coastal Environments: Marrying Management and Science (2008, background): “In California, Spartina alterniflora was first introduced from its native range in eastern North America into SFB in 1975 by the Army Corps of Engineers for marsh restoration (Ayres et al. 2004).”
• The more the better? The role of polyploidy in facilitating plant invasions. (2012, background): “Several Spartina species are highly successful invaders in marshes around the world where they significantly change the physical structure, reduce the biological diversity and affect the ecological function of tidal marshes and mudflats (Thompson, 1991; Ayres et al., 2004; Ainouche et al., 2009).”
• Classical biological control for the protection of natural ecosystems (2010, background): “…the foliosa alterniflora hybrid), S. anglica, S. patens, and S. densiflora (collectively, ‘‘cordgrasses”) have invaded intertidal wetlands on the Pacific coast of the USA (Ayres et al., 2004), transforming mudflats into salt marshes and eliminating critical habitat for birds, fish and shellfish.”
• Effects of the invasive seagrass Halophila stipulacea on the native seagrass, Syringodium filiforme, and associated fish and epibiota communities in the Eastern Caribbean. (2012, background): “…with the arrival of a submerged macrophyte is the loss of open mud and the mudflat’s associated fauna, which proceed to have profound effects at multiple trophic levels (Posey, 1988; Baldwin and Lovvorn, 1994; Neira et al., 2005; Ayres et al., 2004; Levin et al., 2006; Burfeind et al., 2009).”
• HOW INTERACTIONS BETWEEN ECOLOGY AND EVOLUTION INFLUENCE CONTEMPORARY INVASION DYNAMICS (2004, background): “This positive feedback between the increased fitness of hybrids and their greater propensity for hybridization threatens the common and widespread S. foliosa with genetic rarity even though S. alterniflora remains rare and spatially restricted (Ayres et al. 2003, 2004).”
• Ecological and Evolutionary Misadventures of Spartina (2013, background): “Hybrids were highly variable in height, culm width (Ayres et al. 2004a), lateral expansion rates (Ayres & Strong 2010a), flower production, seed production, pollen viability and pollen production (Ayres et al. 2008b), and salinity tolerance (Pakenham-Walsh et al. 2010) (Figure 6).”
