DOI: 10.1002/ece3.7504
Abstract: Abstract Diverse species assemblages theoretically partition along multiple resource axes to maintain niche separation between all species. Temporal partitioning has received less attention than spatial or dietary partitioning but may facilitate niche separation when species… read more here.
