Taxonomic representation among presentations at the Pan-American Society for Evolutionary Developmental Biology 2015 meeting. 57 oral presentation and 164 of 179 published poster abstracts are included in the analysis; of excluded papers seven did not consider particular organisms (theory, modeling, history of science), three were comparisons at a higher taxonomic level, two focused on organisms outside these groups, and three were withdrawn or absent from the meeting. Comparative research using multiple taxa was counted for each group. a Stacked bar graphs at terminal branches (metazoan phyla) show the number of combined oral and poster presentations using each group. Each colored bar segment represents a different class within the named phylum in descending order of frequency (listed alphabetically in case of equal numbers). Presentations containing data from multiple taxa are counted for each group represented. Sponges (Demospongiae), Placozoans, Cnidarians (Anthozoa, Hydrozoa, Schyphozoa), Acoelomorpha (Acoela), Onychophorans (Udeonychophora), Arthropods (Insecta, Crustacea, Arachnida), Nematodes (Chromadorea), Tardigrades (Eutardigrada), Annelids (Polychaeta, Clitellata), Molluscs (Gastropoda, Cephalopoda), Nemerteans (Holopnemertea), Brachiopods (Lingulata), Echinoderms (Actinaria/Echinoidea), Hemichordates (Enteropneusta, Pterobranchia), Cephalochordates (Branchiostomiformes), Tunicates (Pleurogona), Vertebrates (Actinopterygii, Mammalia, Amphibia, Reptilia, Aves/Chrondrichthyes/Hyperoartia, Myxini). b Stacked bar graphs at terminal branches show the number of combined oral and poster presentations for vascular plant taxa. Each colored bar segment represents a different genus in descending order of frequency (listed alphabetically in case of equal numbers). Gymnospermatae, Magnoliids (Aristolchia), Monocots (Erythonium/Pooidae/Zingiberales), Basal Eudicots (Aquilegia), Rosiid II/Malvidae (Arabidopsis/Cardamine, Cleome, Citrus), Asterids I (Jaltomata/Lochrominae/Petunia/Schizanthus/Solanum)
