Islas-Barrios Y., Serrato-Díaz A., Zavala-Hurtado J. A., Octavio-Aguilar P., Callejas-Chavero A., Cornejo-Romero A., Las flores de Myrtillocactus geometrizans (Cactaceae): morfología y artrópodos visitadores en un gradiente geográfico, Botanical Sciences, 2021, 99(1):28-42, doi: 10.17129/botsci.2515
The authors compared flower structure and visiting arthropods at four sites in two Mexican reserves. A sample of 120 flowers yielded 329 arthropods representing 106 morphospecies. Hymenopterans predominated, and visitor assemblages and flower morphology varied between sites. Assignment to potential pollinators relied on functional-group characteristics rather than direct measurements of each species’ pollination effectiveness.
