Non-native species and invasion biology in a megadiverse country: scientometric analysis and ecological interactions in Brazil (2016, background): “…species studied we checked if the introduction was intentional, unintentional or unknown, and, when possible, we determined the number of non-native species (proxy to colonization pressure) and papers (proxy to propagule pressure) related to each vector of introduction (sensu Lockwood et al. 2009).”
MAcroecological Framework for Invasive Aliens (MAFIA): disentangling large-scale context dependence in biological invasions (2020, background): “…patterns of selection from native species pools along different introduction pathways will affect the numbers of species (colonisation pressure; Lockwood et al. 2009) and individuals (propagule pressure; Lockwood et al. 2005; Simberloff 2009) that are introduced to different locations around…”
Climate change, non‐indigenous species and shipping: assessing the risk of species introduction to a high‐Arctic archipelago (2014, background): “Risk is also a function of the number and rate at which NIS are introduced to a region (i.e. propagule pressure – Lockwood et al., 2009).”
A review of current knowledge, risk and ecological impacts associated with non-native freshwater fish introductions in South Africa. (2014, background): “Intensive stocking regimes also resulted in high propagule pressure, further increasing chances of successful establishment (Lockwood et al. 2005; Lockwood et al. 2009).”
Multiple introductions and invasion pathways for the invasive ctenophore Mnemiopsis leidyi in Eurasia (2011, background): “These two components have been classified as propagule pressure and colonization pressure, respectively (Lockwood et al. 2009).”
Invasive Species, Environmental Change and Management, and Health (2010, background): “, the time since the introduction of a taxon to a new area), chance events, and propagule pressure (defined as the number of introduction events) (14), and their spatial distribution codetermine whether a species becomes invasive.”
Quantifying levels of biological invasion: towards the objective classification of invaded and invasible ecosystems (2011, background): “However, the number of species that have had the opportunity to invade (i.e. colonization pressure: Lockwood et al., 2009) should still be considered.”
General hypotheses in invasion ecology (2014, background): “…to consist of: (1) propagule size, which is the average number of individuals involved in a single release event; and (2) propagule number or frequency, which is the average number of release events per unit time (Lockwood et al., 2005, 2009, 2013; Blackburn et al., 2009; Simberloff, 2009).”
Anthropogenic structures and the infiltration of natural benthos by invasive ascidians (2012, methodology): “Lockwood et al. (2009) used the term ‘propagule rain’ to describe localized propagule pressure that enables NIS to spread from initial points of establishment.”
Management of invasive plants through ecological resistance (2017, background): “Colonization pressure is also used to refer to the number of species released into a single location, a variant of propagule pressure (Lockwood et al. 2009).”
Worldwide impact of alien parrots (Aves Psittaciformes) on native biodiversity and environment: a review (2014, background): “…included among those of the “best bird invader” (CASSEY et al. 2004; BLACKBURN et al. 2009) – propagule pressures (i.e. number of released individuals: LOCKWOOD et al. 2009), multiple releases (CASSEY et al. 2004) and the absence of native Psittaciformes all over the introduced ranges (DUNCAN &…”
Progress toward understanding the ecological impacts of nonnative species (2013, background): “18) Colonization pressure Alpert (2006), Lockwood et al. (2009) A higher rate of species introductions increases the probability of a nonnative species that has large impacts.”
