title: Data from: The influence of warming on the biogeographic and phylogenetic dependence of herbivore-plant interactions

description: Evolutionary experience and the phylogenetic relationships of plants have
 both been proposed to influence herbivore-plant interactions and plant
 invasion success. However, the direction and magnitude of these effects,
 and how such patterns are altered with increasing temperature, are rarely
 studied. Through laboratory functional response (FR) experiments, we
 tested whether the per capita feeding efficiency of an invasive generalist
 herbivore, the golden apple snail, Pomacea canaliculata, is dependent on
 the biogeographic origin and phylogenetic relatedness of host plants, and
 how increasing temperature alters these dependencies. The feeding
 efficiency of the herbivore was highest on plant species with which it had
 no shared evolutionary history, i.e. novel plants. Further, amongst
 evolutionarily familiar plants, snail feeding efficiency was higher on
 those species more closely related to the novel plants. However, these
 biogeographic dependencies became less pronounced with increasing
 temperature, whereas the phylogenetic dependence was unaffected.
 Collectively, our findings indicate that the susceptibility of plants to
 this invasive herbivore is mediated by both biogeographic origin and
 phylogenetic relatedness. We hypothesize that warming erodes the influence
 of evolutionary exposure, thereby altering herbivore-plant interactions
 and perhaps the invasion success of plants.
description: phylogenetic functional
 responseIn the functional
 response (FR) experiment, five plant species that share an evolutionary
 history with P. canaliculata were chosen: Alternanthera philoxeroides
 (alligator weed), Eichhornia crassipes (water hyacinth), Ipomoea batatas
 (sweet potato), Myriophyllum aquaticum (parrot feather) and Pistia
 stratiotes (water lettuce). In addition, we chose five plant species with
 which P. canaliculata has had no evolutionary exposure: Apium graveolens
 (Chinese celery), Colocasia esculenta (taro), Ipomoea aquatica (water
 spinach), Hydrocotyle vulgaris (pennywort) and Lactuca sativa (lettuce).We
 collected all host plant species on the day of the experiment to ensure
 their freshness. Each of these species is common in wetlands and
 agricultural areas of South China and the snail was observed to consume
 all these plants to some degree in the laboratory.Then we measured the
 plant consumption by apple snail along 7 plant biomass gradients at 5
 temperature gradients.data for phylogenetic

 species used in this studyTo verify the
 phylogenetic structure of these species, for each of the 10 species we
 searched GenBank for matK gene sequences, which are commonly used in
 published plant phylogenies (Cadotte 2013). We included a gymnosperm
 Platycladus orientalis as the out-group species. Sequences were aligned
 with ClustalW (Thompson et al. 2002). The Bayesian phylogeny was
 reconstructed using BEAST version v1.8.2 (Drummond et al. 2012). The
 Bayesian MCMC chain was run for one million generations, and convergence
 was checked using Tracer version v1.6.0
 (http://beast.bio.ed.ac.uk/Tracer). The maximum clade credibility tree was
 used to quantify phylogenetic pattern by TreeAnnotator version v1.8.2
