highly significantp < 0.0018
The regression analysis, using λ as the dependent variable and only the guanaco population size (in natural logs, LnNtot ) as the independent variable, was highly significant (AIC = -87.847, p < 0.0018, and F = 11.48,) and the resulting regression equation was λ = 1.6373 – 0.0552 (±0.0163) Ln Ntot ( Table 2 ).
