Permethrin-soaked cotton balls are used to protect members of this group against parasitic Philornis downsi.
ALX1 haplotypes are linked to polymorphic craniofacial development in this highly introgressive species group. Permethrin-soaked cotton balls are used to protect members of this group against parasitic Philornis downsi. Studies of these organisms on Daphne Major show (*) oscillatory selection with climate in work by Peter and Rosemary Grant. Their name was popularized by David Lack, who interpreted bill shape variation as food niche specialization. For 10 points, name this group of tanagers that underwent an adaptive radiation on the Galápagos Islands.
