Larval Biology Of Some Utah Chrysididae, Bakary Vassery Ouayogode
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Biologies of eight chrysidid species were described. These wasps parasitized bees and wasps collected in trap nests set at several sites in two canyons near Logan, Utah. The completed nests were taken to the laboratory and the parasitized ones were kept for study of the development a l biology and behavior of both host and parasites.
The larval stages of Chrysura smaragdicolor, Chrysura sonorensis, Chrysis parkeri, Chrysis derivata, Chrysis coerulans, Cerotachrysis enhuycki, Trichrysis doriae and Hedychridium solierellae were studied. Omalus iridescens and Omalus purpuratus larvae were observed only in the fifth instar. The major …

An Investigation Of Salinity Fluctuations In Soils Of A Northern Utah Marshland, Gary Roy Newman
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Ogden Bay Waterfowl Management Area is one of many marshlands bordering the Great Salt Lake that are extremely important as breeding habitats for North American waterfowl. Salinity, both of surface and interstitial waters, is an important factor in maintaining a suitable habitat within the marsh. For this reason, a study was undertaken to determine the factors affecting the salinity of surface and interstitial waters. A small (approx. 100 acre) subunit was studied extensively to determine; 1) variations in surface water salinity with flowrate and water level; and 2) variation in interstitial water salinity with depth and location within the subunit. …
