An elevational gradient in floral traits and pollinator assemblages in the Neotropical species Costus guanaiensis var. tarmicus in Peru. [PDF]
Ecol Evol, 2023 We analyzed floral traits and pollinator assemblages in the Neotropical species Costus guanaiensis var. tarmicus along a steep elevational gradient in Peru. Results show floral traits and pollinator assemblage variation along the elevational gradient. We examined our results considering two hypotheses: (1) local adaptation to different bee assemblages ...
