From: Response of reindeer mating time to climatic variability
Hypothesized path model for how mating time (‘MT’) of reindeer is affected directly and indirectly by climatic variability from 1996 to 2013 in the Kutuharju herd, northern Finland. The definitions and time windows of the weather variables (‘MinTemp’, ‘Prec’, ‘Snow’) are provided in the Methods section, as well as the explanation of (a) the hypothesized paths. ‘BWSept’ represents the pre-rut body weight of males and females (measured in September), ‘DENS’ the population density, ‘PM’ the proportion of males in the herd and ‘♂ ASTR’ the male age structure (see text for details). All lines in the diagram represent a specific linear mixed-effects model. The path model in (b) shows the standardized coefficients and SEs for paths associated with statistically significant effects. Nonsignificant paths (P > 0.05) shown as darker lines in panel (a) have been set as light gray lines in panel (b); significant paths with good evidence (P < 0.05) for an effect as thick solid lines (b) and paths with a weak effect (P ~ 0.05) as dotted line (b)
