Undesirable aliens: factors determining the distribution of three invasive bird species in Singapore (2003, background): “…structure and parameter estimates are not uncommon, and can be caused by a number of factors, such as random or unpredicted fluctuations in the environment or lack of precise knowledge of birds or habitats (e.g. our inability to measure vegetation beyond a central strip) (Gutzwiller & Barrow 2001).”
A Multiscale Landscape Approach to Predicting Bird and Moth Rarity Hotspots in a Threatened Pitch Pine–Scrub Oak Community (2004, methodology): “To assess model predictive ability we used both the conservative cut point of 0.5 (Gutzwiller & Barrow 2001) and the optimal cut point (for an explanation of how optimal cut point was determined, see Appendix 3) to calculate correct classification rates, sensitivity (ability of the model to…”
Absent or undetected? Effects of non-detection of species occurrence on wildlife-habitat models (2004, background): “Uncertainties associated with predictions of occupancy models have been attributed to temporal variation in animal–landscape relationships, stochastic variation in environmental variables, and assumptions about model structure (Gutzwiller and Barrow, 2001).”
