Widespread species often show geographic variation in thermally-sensitive traits, providing insight into how species respond to shifts in temperature through time. Such patterns may arise from phenotypic plasticity, genetic adaptation, or their interaction. In some cases, the effects of genotype and temperature may act together to reduce, or to exacerbate,(More)
Many members of the Orchidaceae offer no rewards to pollinators and attract them through deception. One common approach is to mimic the specific floral signals of co-flowering species that are rewarding (Batesian floral mimicry) to exploit their pollinators. We investigated two putative Batesian floral mimics, Disa gladioliflora subsp. capricornis and Disa(More)
