Allee Effects, Propagule Pressure and the Probability of Establishment: Risk Analysis for Biological Invasions (2006, methodology): “2003), we will focus on two important conceptual distinctions that pertain to the invasion process and relate to the concept of propagule pressure in general ways: (1) the difference between closed populations, in which introductions are isolated events, and open populations in which introductions a”
Ecological non-linear state space model selection via adaptive particle Markov chain Monte Carlo (AdPMCMC) (2010, background): “Two of these models include weak or strong Allee effects which can be important in ecological populations [Dennis, 2002].”
Allee effects in a discrete-time host-parasitoid model (2006, background): “Recently, there has been a growing interest in studying Allee effects using either deterministic or stochastic models 2 5 7 12-14 16 .”
Model complexity and population predictions. The alpine marmot as a case study (2002, result): “In view of the growing body of evidence supporting the importance of Allee effects, our findings concur with other recent work (Dennis 2002) recommending that modellers should be careful to consider the role of Allee effects in their study species.”
Spread of invasive Phragmites australis in estuaries with differing degrees of development: genetic patterns, Allee effects and interpretation (2010, background): “Allee effects, ‘positive relationships between fitness and density or number of conspecific individuals’ (Allee 1931; Stephens, Sutherland & Freckleton 1999; Dennis 2002), have recently *Correspondence author.”
Mathematical modeling of population dynamics with Allee effect (2016, methodology): “By using diffusion approximation, Dennis [26] showed that extinction in a stochastic model with an Allee effect depended on the initial population size.”
Climatic Suitability, Life‐History Traits, Introduction Effort, and the Establishment and Spread of Introduced Mammals in Australia (2004, background): “There is a strong theoretical basis for the importance of introduction effort: the likelihood of a population becoming extinct is inversely related to population size because of the combined effects of demographic and environmental stochasticity and random catastrophe (Lande 1993; Dennis 2002).”
Demographic and environmental stochasticity in predator–prey metapopulation dynamics (2004, background): “For instance, demographic stochastic processes such as an individual’s probability of reproduction, survival or dispersal are known to affect the persistence of populations and are particularly manifest in low populations (Lande 1998; Dennis 2002).”
The Role of Propagule Pressure in Biological Invasions (2009, background): “…1931) as stylized behavior of vertebrates that fails when population density falls below a threshold density, but the concept has been generalized (e.g., Courchamp et al. 1999, Dennis 2002, Lockwood et al. 2007) to encompass any reduction in population growth rates at low population densities.”

Metapopulation consequences of site fidelity for colonially breeding mammals and birds (2005, background): “Secondly, patterns of occupancy will be confounded by environmental stochasticity especially if it is strong enough to cause local, catastrophic extinctions (Dennis 2002).”
