Biography

Biography


I am a Utahn and citizen of the world. My personal and academic life intertwines these two ideas. I love the land and people of Utah and the world. I have guided my education to serve all. I believe I serve best by getting humans out in the more "natural" world so its gifts and services to us are more apparent, appreciated, guarded, and enhanced.

Teaching Interests


I believe firmly in a general education and devote considerable effort to teaching the wonders of biology at all scales in a framework of human interest and stewardship.

Research Interests


I wander freely in researching all living things. I particularly focus on insects in aquatic and desert habitats. My research interests lie at the intersections of taxonomy, systematics, ecology, and evolution. All as humans are incorporated as stewards of the living world.

IBS 2019 Humboldt Meeting & 2nd Latin American Biogeography Meeting. Plecoptera are aquatic insects that live in clean, well-oxygenated fresh water as immatures They are generally more
    prevalent in temperate streams and lakes than in tropical ones But numerous exceptions and radiations exist They
    have a clear fossil history that extends to the Permian They are used as bioindicators of desirable water quality by
    managers and ecologists around the world The phylogeny of the group is largely stable, with notable exceptions In
    this talk I will summarize the rather odd distributional history of the order and highlight research into their use of
    extreme habitats of glaciers, oligotrophic lakes, hyporheic zones, and life history adjustments to alpine and arctic
    regions I will also address some current conservation and extinction issues with respect to local and global change. August, 2019.

  • Nelson CR. Life Histories of stoneflies: odd evolutionary variations Insecta: Plecoptera. Department of Entomology Seminar. Stoneflies (Plecoptera) are aquatic insects with general attributes attractive to scientists and members of the general public for a variety of reasons They are among the most sensitive of freshwater macroinvertebrates to anthropogenic environmental changes (chemical pollution, organic enrichment, heat pollution, etc) and are used as indicator species of desirable water conditions by managers of freshwater worldwide This sensitivity also makes many of their populations susceptible to extinction/extirpation/speciation in local areas on geologic time scales This coincides in many species with winglessness so long-distance dispersal is not possible to escape environmental problems Thus they are model organisms for studies of vicariance biogeography as well as “canaries in the mine shaft” of studies of climate change All these attributes make them share streams with coldwater fishes like trout and some bass, thus darlings of the flyfishing world Additionally more recent work has shown that the life cycles and habitat choices stoneflies make have relevant in evolutionary models of specialization and speciation, including specialization to deep lakes and icy streams on glaciers In this talk loaded with beautiful images I will summarize the generalities and highlight the more extremophile habits of these interesting organisms.

A comparison of robber fly (Diptera: Asilidae) communities found in native and non-native plant associations in the Great Basin of western North America C Riley Nelson1, Robert L Johnson1, and Val J Anderson2 We inventoried robber fly composition (Diptera: Asilidae) at three sites in the eastern Great Basin of western North America Plant communities in these vast habitats often consist of Utah juniper woodland, sagebrush shrubland, cheatgrass grassland, and crested wheatgrass grassland Juniper woodland and sagebrush shrubland are native associations in the region while cheatgrass grassland is a more annually timed invasive community that often establishes after fire or severe grazing pressure Crested wheatgrass, a non-native bunchgrass is often planted in disturbed sites (after fire or severe grazing) to stabilize the abiotic habitat and allow reestablishment of more native biotic associations as a bridge species We sampled these four communities where they were contiguous in three widely separated locations using malaise traps evenly arranged across the sample area A total of 2,438 robber flies were collected from the traps over the course of two years We identified the asilids as belonging to 24 genera and 58 species Composition was significantly different between all habitat types with the greatest diversity occurring in juniper woodlands, followed by sagebrush, cheatgrass, and crested wheatgrass Thus the native woody communities were richer than the non-native grasslands The conversion of native habitats to cheatgrass favors robber flies in the genus Dicropaltum but that preference is not found in the superficially similar grassland community dominated by crested wheatgrass Other patterns in the robber fly communities will be explored as well The enhanced richness and abundance of robber flies in native juniper woodlands and sagebrush shrubland compared to the two exotic grassland systems sheds light on their contribution towards regional biodiversity in this faunal group overlooked by land managers and researchers 1Department of Biology and Monte L Bean Museum, Brigham Young University, Provo, Utah 84602 USA 2Department of Plant and Wildlife Sciences, Brigham Young University, Provo, Utah 84602 USA email: rileynelson@byuedu; robert_johnson@byuedu; val_anderson@byuedu .
