Population Fluctuations And Distribution Of Staging Eared Grebes (Podiceps Nigricollis) In North America, Anthony J. Roberts, Michael R. Conover, John Luft, John Neil

Eared Grebes (Podiceps nigricollis Brehm, 1831) use saline ecosystems throughout much of their life cycle, and greater than 90% of the North American population stage during fall at two hypersaline lakes. At one of these lakes, Great Salt Lake (GSL), Utah, a commercial harvest of brine shrimp (Artemia franciscana Kellogg, 1906) cysts occurs during fall and may impact Eared Grebe populations. We used photo surveys on the other hypersaline lake, Mono Lake, California, and on the GSL, as well as aerial counts on the GSL, to describe population fluctuations of Eared Grebes staging on these lakes. The long-term (1997–2012) Eared …
Older Adolescents’ Self-Determined Motivations To Disclose Their Hiv Status, Ann Gillard, Mark F. Roark
Older Adolescents’ Self-Determined Motivations To Disclose Their Hiv Status, Ann Gillard, Mark F. Roark

Disclosure of HIV status is an important topic for youth living with HIV/AIDS, yet theoretical frameworks for understanding HIV disclosure motivations have been poorly applied. Self-determination theory (SDT) proposes that people are at optimal functioning when they are engaging in activities that are interesting and enlivening. This study utilized SDT to understand young adults’ motivations to disclose their HIV status. Interviews and observations were conducted with nine youth aged 17–19 and two adult staff. Results indicate that SDT is useful for understanding types of motivation (i.e., amotivation, controlled, and autonomous motivation) to disclose. Amotivation was the most common type of …
Effect Of Lactose Monolaurate And High Intensity Ultrasound On Crystallization Behavior Of Anydrous Milk Fat, Ashwini Wagh, M. K. Walsh, Silvana Martini
Effect Of Lactose Monolaurate And High Intensity Ultrasound On Crystallization Behavior Of Anydrous Milk Fat, Ashwini Wagh, M. K. Walsh, Silvana Martini
Nutrition, Dietetics, and Food Sciences Faculty Publications
Crystallization behavior of anhydrous milk fat (AMF) was studied with the addition of 0.025 and 0.05 % lactose monolaurate (LML). The crystallization behavior was studied at low (ΔT = 3 °C) and high supercooling (ΔT = 6 °C). Polarized light microscopy and laser turbidimetry indicated a delay in crystallization on addition of 0.025 % and 0.05 % LML or Tween 20 to AMF. High intensity ultrasound (HIU) was applied to AMF samples with 0.05 % LML and lower supercooling (T c = 31 °C; ΔT = 3 °C). HIU application in AMF and AMF + 0.05 % LML induced crystallization …
Physical Properties Of Pectin Aqueous Solutions Containing Sunflower Wax, Erica R. Baümler, Amalia A. Carelli, Silvana Martini

The aim of this study is to investigate the physical properties of aqueous solutions of pectin (PA) containing sunflower wax (SFW), which are used as a basis for producing edible films. The stability and the rheological and microstructural characteristics of SFW/PA mixtures were evaluated. SFW/PA mixtures formed oil-in-water emulsions that were milky and opaque in appearance and were stable towards phase separation. Polarized micrographs revealed the presence of wax crystals, whose size decreased as pectin concentration increased. The rheological behavior of the aqueous solutions of pectin containing different amounts of SFW were best described by the generalized power law model …
Effects Of Increasing Age On Fecundity Of Old-Aged Canada Geese (Branta Canadensis), Michael R. Conover
Effects Of Increasing Age On Fecundity Of Old-Aged Canada Geese (Branta Canadensis), Michael R. Conover
Wildland Resources Faculty Publications
Senescence is a decline in body function with advanced age that manifests itself in birds as a decrease in survival rates or reproduction. Senescence is difficult to study in free-ranging birds because few birds reach old age and few studies last long enough to identify those birds that do. For 21 years, I studied lifelong reproduction among Canada Geese (Branta canadensis) nesting in New Haven County, Connecticut. These data were used to determine the impact of old age on female and male fecundity during the current year and during the remainder of the birds' lives. Old-aged geese were …
Ungulate Damage To Safflower In Utah, Michael J. Haney, Michael R. Conover
Ungulate Damage To Safflower In Utah, Michael J. Haney, Michael R. Conover
Wildland Resources Faculty Publications
In Utah, farmers are concerned that ungulates are damaging safflower (Carthamus tinctorius) fields. We examined elk (Cervus elaphus) and mule deer (Odocoileus hemionus) damage to safflower production in San Juan County, Utah during 2009 and 2010. We collected data on damaged safflower plants within 28 fields, totaling 1,581 ha (13 fields totaling 963 ha during 2009; 15 fields totaling 618 ha during 2010). We compared 3 methods to assess yield losses: ungulate-proof exclosures, adjacent plant compensation method, and counting the number of damaged plants in 50-m transects (safflower count method). Exclosures were of limited use because they could not be …

Snap-Ed nutrition education classes and food demonstrations allow for observation and modeling of correct food safety practices. Through the Utah State University’s Supplemental Nutrition Assistance Program-Education (SNAPEd), low-income participants completing four or more nutrition education lessons completed a retrospective post/pre behavior questionnaire. Results demonstrated increased intent to follow food safety practices by properly cooking, chilling, and separating food items, as well as properly cleaning food preparation surfaces.

Benefits of consuming fruits and vegetables are documented, yet more than 75 percent of Americans do not eat the recommended servings advised by the current Dietary Guidelines for Americans and MyPlate. Through a self-reported post/pre behavior checklist, the Utah State University Supplemental Nutrition Assistance Program–Education (SNAP-Ed) demonstrated an increase in fruit and vegetable consumption in low-income individuals through consistent education incorporating four or more lessons over a period of five years.
