“…Interactive effects between density and resource levels, or other environmental conditions that affect energetic demand, play large roles in a variety of ecological issues, including population regulation (Dennis & Otten, 2000;Fowler & Pease, 2010;Gamelon et al, 2017;Spanio, Hidalgo, & Munoz, 2017), pairwise species interactions (Dallalio, Brand, & Grant, 2017;Dunson & Travis, 1991), and theories for the role of competition in structuring multi-species assemblages (Grime & Pierce, 2012;Tilman, 1988).
