text: Shen et al. suggest that populations subject to habitat saturation are likely to be living in groups because of the benefits derived from group-defended resources (“resource defense benefits”) favored by spatial environmental variability, particularly in temporally stable environments, while groups that form in order to overcome difficulties in successful breeding are likely to be gaining benefits derived directly from cooperative group behaviors (“collective action benefits”) favored in temporally variable environments.
