Nesting Cavity Temperature Impacts Nesting Choice and Development of the Alfalfa Leafcutting Bee (Megachile rotundata)
(North Dakota State University, 2019)
Megachile rotundata is an agriculturally important pollinator of alfalfa and is not doing well in the U.S due to a 50% return rate (Pitts-Singer and Bosch, 2011). Nesting boxes can reach temperatures between 35˚C-48˚C (see ...
Environmental Impacts on Behavior and Personality in the Caviomorph Rodent, Octodon degus
(North Dakota State University, 2019)
Environmental factors can have large impacts in shaping the way that animals behave. Biotic elements, such as predators and conspecifics that individuals interact with, are two environmental factors that animals may encounter ...
Physiological Mechanisms Underpinning Growth and Aging in Wild Birds
(North Dakota State University, 2019)
Life-history trade-offs have been well-documented within the literature through correlational and experimental studies. However, the physiological mechanisms underlying these trade-offs are less understood. Currently, there ...
Telomere Length and Senescence in a Long-lived Fish (Ictiobus cyprinellus)
(North Dakota State University, 2019)
The pattern of shorter telomere lengths in older individuals has been observed across many vertebrates, but has not been well-documented in bony fishes. Bony fish (i.e., Class Osteichthyes) represent the most speciose and ...
Peripheral Hormone Interactions with the Growth Hormone-Insulin-Like Growth Factor (GH-IGF) System in Rainbow Trout
(North Dakota State University, 2019)
The growth of vertebrates is primarily regulated by the growth hormone-insulin-like growth factor (GH-IGF) system, but not in isolation. The central question of this dissertation was how do other hormones peripheral to the ...
