Population Viability Analyses with Demographically and Spatially Structured Models (2004, background): “The factors that cause such a decline (e.g., difficulty in finding a mate or disruption of social functions) are collectively called Allee effects (see Lacy 2000a).”
Extinction risk in fragmented habitats (2004, methodology): “VORTEX version 8.41 (Lacy, 1993, 2000; Miller & Lacy, 1999) was used to model the 30 species used in this study.”
Estimates of minimum viable population sizes for vertebrates and factors influencing those estimates (2003, methodology): “However, since we use a population ceiling, conservative estimates of inbreeding depression, and do not model Allee effects, we may underestimate MVP (Lacy, 1993, 2000; Lindenmayer et al., 1995).”
How accurate are population models? Lessons from landscape-scale tests in a fragmented system (2002, methodology): “…between model predictions and actual field data was obtained only when model complexity was added (such as matrix effects on dispersal mortality, the ability to forage in the matrix and ⁄or the influence of habitat quality on within-patch population size) (Lacy 2000; Lindenmayer et al. 2000).”
Population dynamics of reintroduced forest birds on New Zealand islands (2002, background): “However, we have found it necessary to modify the procedures in VORTEX to incorporate some of our models.”
Using adaptive management to determine requirements of re‐introduced populations: the case of the New Zealand hihi (2007, unknown): “Initially we used the package vortex (Lacy 2000) but later constructed population models in Microsoft® Excel spreadsheets.”
