Models with Δ AICc < 2 are in bold font.
a We weighted network edges by association rate; the number of times two deer were within 25m of one another at the same time divided by the total number of simultaneous locations.
b Gestation (1 Jan– 14 May; n = 12), fawning (15 May– 31 Aug; n = 10), rut (1 Sep– 31 Dec; n = 6).
c [+] and [–] indicate the direction of each variable’s effect. Variables are described in the footnote of Table 3.
d All models with Δ AICc <2 had F-statistics >95% of randomized values except the home range overlap model during fawning.
