In 1998, DNA sequence data were obtained and/or analyzed from hundreds of taxa, including: cyanobacteria, lichenized ascomycetes and basidiomycetes, non-lichenized ascomycetes, mushrooms, club-mosses, quillworts, horsetails, whisk ferns, royal ferns, filmy ferns, polypody ferns, water ferns, tree ferns, pyramidellid snails, clams, snapping shrimp, corals, batflies, rove beetles, fruit flies, butterflyfish, poison-dart frogs, cricket frogs, natricine snakes, homalopsine sea snakes, manakins, ground rollers, antbirds, cactus wrens, toucans, thrushes, warblers, honeyeaters, shrews, tenrecs, fruit bats, microbats, rodents, primates, carnivorans, and ungulates. These taxa come from almost every imaginable habitat - temperate and tropical rainforests and dry forests, grasslands, streams, ponds, estuaries, and coral reefs - and from every continent except Antarctica, as well as numerous islands. The many areas of inquiry pursued by these researchers include the origins of symbiosis, the evolution of life history traits, rates of evolutionary change, biogeography, conservation, sexual selection, speciation, and natural selection at the molecular level. More than 35 new and continuing projects used the DNA sequencing facilities in 1998.
