Breeding Season Ecology And Demography Of Lesser Scaup (Aythya Affinis) At Red Rock Lakes National Wildlife Refuge, Jeffrey M. Warren May 2018

Breeding Season Ecology And Demography Of Lesser Scaup (Aythya Affinis) At Red Rock Lakes National Wildlife Refuge, Jeffrey M. Warren

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

It is hypothesized that individuals make reproductive decisions based on current assessments of their physiological condition and environmental conditions. For female lesser scaup (Aythya affinis), breeding occurs after an energetically costly spring migration. Increasing fat reserves (i.e., ‘body condition’) prior to breeding allows a female to produce a larger clutch of eggs, but time spent gaining body condition is costly in terms of time allowed to raise ducklings before freezing conditions in the fall. In Chapter 2 I explored rate of pre-breeding body condition gain in female lesser scaup, and how that rate influenced clutch size. Spring phenology, …


The Effect Of The State Giant Traveling Map Of Montana On The Geographic Literacy Of Fourth Graders In Western Montana, Rebecca A. Kranitz Jan 2018

The Effect Of The State Giant Traveling Map Of Montana On The Geographic Literacy Of Fourth Graders In Western Montana, Rebecca A. Kranitz

Graduate Student Theses, Dissertations, & Professional Papers

A complex set of factors and processes operating within the United States public education system contribute to high rates of geographic illiteracy in the majority of young adults. These factors include, but are not limited to, a lack of structured federal controls over state geography requirements, insufficient time to implement effective geography curricula, and inadequate assessment techniques. To raise rates of geographic literacy, the National Geographic Society (NGS) created the State Giant Traveling Maps (SGTM) to actively engage students in a geography education experience that simultaneously promotes positive attitudes towards geography while strengthening student map skills. The SGTMs incorporate a …
