On second thought,I guess either amount of daylight or angle of sun is essentially one in the same,if the local animals evolve to rut at a certain time of year it doesn’t matter,both the angle and amount of sunlight is constant from year to year.
Now that said,I wonder if you transplanted a native cow moose from Maine to Alaska would she be messed up and come into estrous much sooner then her Alaska cousins?Likewise,if you took an AK moose and moved her to NB maybe she wouldn’t come into estrous until late October when the available daylight replicates that of an Alaskan September?
Around the equinox, everywhere has has pretty much some amount of daylight hours.
