Datasets usually provide raw data for analysis. This raw data often comes in spreadsheet form, but can be any collection of data, on which analysis can be performed.
In 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.
