(b) Inter-annual variability and environment drivers out of splitting up speed
Similar to the books, a splitting up skills is actually submitted when at least one member of a breeding couple re-paired with yet another spouse about after the seasons, as the earlier lover was still real time . We utilized a great quasi-binomial GLM in order to design the population splitting up rates as the a features out of SSTA and you can Breeze.
(c) Likelihood of splitting up, timing from inability and you may environment effects
To analyze the details impacting the possibilities of splitting up, i experienced the new come upon records of all of the low-widowed females. To help you limit all of our studies solely for the density out of divorce proceedings events, the women one to sustained mate loss was indeed excluded; so it led to good dataset spanning 2899 breeding attempts recorded to have 424 female between your 2004 together with 2019 year. Annually, people you are going to often: remain loyal and you will companion along with their previous companion (coded given that ‘0′); forget about a reproduction test when you find yourself their lover in addition to didn’t take to reproduction (also coded since ‘0′); divorce case and you can reproduce with a new lover (coded just like the ‘1′); or skip a breeding sample when you find yourself its past companion bred having various other companion (in addition to regarded as a separation and divorce and thus coded just like the ‘1′). Playing with binomial GLMMs, i modelled the fresh density off separation given that a purpose of the brand new pursuing the explanatory details: anyone previous 12 months breeding score; SSTA and you may Wind. …
