WebIf they were something you'd want to report, I'd question why you consider Species a random effect. Usually, I'd report the fixed effects and the variances of the random effects. (A random effect with only three subjects is very questionable. That's not enough to estimate variances reliably. A fixed effects model should be used here.) – WebUsing multi-level mixed-effects models for characterizing growth, survival and fecundity in a long-term data set Journal of Applied Ecology, 40 pp 481 - 493 Goldstein, H., Burgess, S. and McConnell, B.
