Testosterone (T) and Triiodothyronine (T3) in Franklin’s Gull (Leucophaeus Pipixcan) Eggs
(North Dakota State University, 2018)
Maternally-derived hormones are known to influence the growth and development of offspring. The differential deposition of these maternally-derived hormones into egg yolk is one way by which females can alter and impact ...
Eat to Reproduce: The Role of Diet Quantity on Honey Bee (Apis Mellifera) Caste Determination
(North Dakota State University, 2017)
The received wisdom is that diet quality drives this queen-worker dichotomy, even though diet quantity differs significantly between queen and worker diet. Diet quantity likely determines honey bee caste; yet it has never ...
Environmental Components of Phenotypic Variation Dietary and Trans-Generational Effects on Behavior
(North Dakota State University, 2017)
Phenotypic variation, or the total variation in a trait, and its components are of great importance in the fields of evolutionary and behavioral ecology. Phenotypic variation can be broken down into both environmental and ...
Characterization of Variation in Growth Performance in Inbred Strains of Zebrafish (Danio Rerio)
(North Dakota State University, 2012)
Although zebrafish have been a widely utilized model organism for several decades, there is little information available on physiological variation underlying genetic variation among the commonly used inbred strains. This ...
