Data from: Assortative flocking in crossbills and implications for ecological speciation

Julie W. Smith, Stephanie M. Sjoberg, Matthew C. Mueller & Craig W. Benkman
How reproductive isolation is related to divergent natural selection is a central question in speciation. Here we focus on several ecologically specialised taxa or “call types” of red crossbills (Loxia curvirostra complex), one of the few groups of birds providing much evidence for ecological speciation. Call types differ in bill sizes and feeding capabilities, and also differ in vocalizations, such that contact calls provide information on crossbill phenotype. We found that two call types of...

Data from: Consistency and variation in phenotypic selection exerted by a community of seed predators

Craig W. Benkman, Julie W. Smith, Monika Maier, Leif Hansen & Matt V. Talluto
Phenotypic selection that is sustained over time underlies both anagenesis and cladogenesis, but the conditions that lead to such selection and what causes variation in selection are not well known. We measured the selection exerted by three species of predispersal seed predators of lodgepole pine (Pinus contorta latifolia) in the South Hills, Idaho and found that net selection on different cone and seed traits exerted by red crossbills (Loxia curvirostra) and cone borer moths (Eucosma...
