Observations of Interspecific Amplexus Between Western North American Ranid Frogs and the Introduced American Bullfrog (Rana catesbeiana) and an Hypothesis Concerning Breeding Interference

Reproductive interference: ecological and evolutionary consequences of interspecific promiscuity

“…For example, terms that have been used to describe interspecific sexual interactions between plants include ''interspecific pollen transfer'' (Waser 1978b), ''improper pollen transfer'' (Rathcke 1983), ''competition through interspecific pollen transfer'' (Waser 1983), ''heterospecific pollen deposition'' (Morales and Traveset 2008), and ''pollinator-mediated competition'' (Runquist and Stanton 2013). In animals, ''sexual selection for host plant fidelity'' (Colwell 1986), ''sexual competition'' (Yoshimura and Clark 1994), ''breeding interference'' (Pearl et al 2005), ''sexual interference'' (Dame and Petren 2006), and ''noisy neighbor'' (Coyne and Orr 2004;Mullen and Andrés 2007) have all been used to describe interspecific sexual interactions (see Gröning and Hochkirch 2008 for additional synonyms). Although ''reproductive interference'' is the term most frequently used by zoologists , botanists rarely use it (but see Armbruster and Herzig 1984;Harder et al 1993;Takakura et al 2009;Eaton et al 2012).…”

The Reproductive Biology of the InvasiveLithobates catesbeianus(Amphibia: Anura)

“…This species exerts a negative impact on natural populations and communities of other species through predation, competition (Kupferberg, 1997;Pearl et al, 2005;Wu et al, 2005), and transmission of pathogens (Schloegel et al, 2009).…”

Age and body size in four introduced populations of the American bullfrog, Lithobates catesbeianus (Ranidae)

“…It was ascertained that this large frog can threaten native amphibians through different actions, among which are direct predation (Werner et al 1995;Jankowski & Orchard 2013), habitat competition (Snow & Witmer 2011), sexual interference (Pearl et al 2005), and transmission of pathogens including emerging infectious diseases such as ranavirus (Sharifian-Fard et al 2011) and chytrid fungus Batrachochytrium dendrobatidis (Daszak et al 2004;Garner et al 2006;Jankowski & Orchard 2013;Miaud et al 2016). This bullfrog was introduced in many parts of North America (including the Hawaiian Islands) and in many other areas, such as the Caribbean region, South America, Asia and Europe (Ficetola et al 2007a;Snow & Witmer 2010;Both et al 2011;Vannini et al 2015), mainly with the purpose of frog farming.…”
