“…When a population is isolated, dispersal of females leads to temporary or permanent lost from the breeding population (Allée and al. 1949;Wells, Strauss and al. 1998).…”

“…They chose a slightly phenomenological approach, did not explicitly consider the effective search area S and instead focused on individual ''meeting rates''. For 1 : 1 sex ratio, they derived the RH form (18) with y ¼ 2=ð2aatÞ where a scales the meeting rate of randomly moving individuals, a is the probability of mating success given that a male-female meeting occurred, and t is the length of the reproductive period (Wells et al, 1998). For a biased sex ratio, they derived form (20) with S formally replaced by 2aat (Wells et al, 1990).…”

“…For a biased sex ratio, they derived form (20) with S formally replaced by 2aat (Wells et al, 1990). Stephan & Wissel (1994), Wells et al (1998) and Grevstad (1999) used the PC form (19). It assumes that a female mates with a male upon encounter with a fixed probability a and that the (mean) number of meetings a female has with males during the reproductive period is proportional to mN: The proportionality constant equals S provided that the male distribution is Poisson and independent at each time instant (see above).…”

“…This forces a model to ignore sex-specific differences not only in life-history traits, such as body size, survival, and age of maturation (Bradley et al 1980;Fairbairn 1997;Onyango et al 2013), but also in movement behaviors, such as tendency to leave the natal area and total distance traveled (Greenwood 1980;Waser and Jones 1983;Clarke et al 1997;Miller et al 2011). An added complication of sexually reproducing species is the requirement that individuals find mate(s) before reproducing, which can be increasingly difficult at low densities (Dennis 1989;Wells et al 1998;Courchamp et al 2008). Difficulties in finding mates can cause an Allee effect, where population growth decreases at low densities (Stephens et al 1999).…”
