Northern Leopard Frogs in North Dakota: Assessing the Conservation Status of a Widespread Amphibian Species
(North Dakota State University, 2015)
North Dakota’s midcontinent location within the Prairie Pothole Region is widely known
for the dense wetlands. These highly productive wetlands are mixed within an agricultural
mosaic which places increased pressure on ...
Examination of the Period of Preparation for Breeding in Male and Female Songbirds
(North Dakota State University, 2017)
In virtually all species, reproduction must be precisely timed to coordinate breeding and rearing of offspring with favorable conditions. It is imperative for individuals to time the highest energetic cost to themselves ...
Chironomids Then and Now: Climate Change Effects on a Tundra Food Web in the Alaskan Arctic
(North Dakota State University, 2019)
Although climate change is a global phenomenon, the Arctic is warming faster than any other region on earth. These climatic changes have driven rapid regional changes over the past half-century in both the physical landscape ...
Understanding the Relationships between Plant Communities, Fish Communities, and Sediment Chemistry in Pristine Shallow Lake Wetlands, Red Lake, MN
(North Dakota State University, 2016)
Over 90% wetland loss in many areas of the United States has triggered extreme concern for declining biodiversity and loss of ecosystem services. Studies assessing ecological characteristics of unaltered wetlands are ...
Sperm Telomere Dynamics: Natural Variation and Sensitivity to Environmental Influences in House Sparrows (Passer domesticus)
(North Dakota State University, 2018)
Understanding the mechanisms that contribute to variation in lifespan is of central importance to diverse fields including life history theory. Although the causes of aging are not fully understood, telomere dynamics (length ...
Biogeochemistry of Wet Ecosystems from Root Zone to Landscape
(North Dakota State University, 2012)
The biogeochemistry of wetland ecosystems varies, causing them to act as sources, sinks, filters or transformers of nutrients and pollutants. Wetland plants play important roles in the cycling of elements in wet ecosystems. ...
Processing Trade-offs in a Cellulosic Biorefinery
(North Dakota State University, 2017)
Commercial scale cellulosic biorefineries face significant challenges to produce low-cost fermentable sugar from biomass. Biorefinery processing steps are interrelated and trade-offs between process parameters impact the ...
From Bray-Curtis Ordination to Markov Chain Monte Carlo Simulation: Assessing Anthropogenically-Induced andor Climatically-Induced Changes in Arboreal Ecosystems
(North Dakota State University, 2013)
Mapping forest resources is useful for identifying threat patterns and monitoring changes associated with landscapes. Remote Sensing and Geographic Information Science techniques are effective tools used to identify and ...
Habitat Use and Foraging Ecology of Bats in North Dakota
(North Dakota State University, 2016)
Habitat use is a key component to understanding the conservation needs of species. While an array of quantitative analyses for studying fine-scale habitat use and selection have been developed, such methods have rarely ...
The Effect of Zinc Oxide Nanoparticles on Plants, and on Host-Pathogen Interactions
(North Dakota State University, 2019)
Zinc oxide nanoparticles (ZnO NPs) are a type of engineered nanomaterial that is currently being explored for use in different aspects of agriculture. So far, research on this area is limited to evaluating the phenotypical ...
