Interactive Effects Of Increased Nestbox Temperature And Vitamin E On Nestling Growth Are Attenuated By Plasticity In Female Incubation Effort, Paige A. Duncan, Ashley M. Tauber, Scott K. Sakaluk, Charles F. Thompson
Interactive Effects Of Increased Nestbox Temperature And Vitamin E On Nestling Growth Are Attenuated By Plasticity In Female Incubation Effort, Paige A. Duncan, Ashley M. Tauber, Scott K. Sakaluk, Charles F. Thompson
Faculty Publications – Biological Sciences
In recent years, temperatures have increased globally, and nestlings of many bird species are likely regularly exposed to increased temperatures both pre- and post-natally. Even small increases in nest temperature during incubation affect offspring growth and survival in a variety of species, one cause of which is thought to be increased production of pro-oxidants in embryos and nestlings. Defences marshalled in response to this oxidative stress could, in turn, result in trade-offs that lead to reduced survival or growth. If so, any downstream negative effects on nestlings of increased ambient temperatures during incubation could be counteracted by increasing their antioxidant …
Precipitation And Greenness In Pastoral Lands Of East Turkana, Kenya, Paul Akpejeluh
Precipitation And Greenness In Pastoral Lands Of East Turkana, Kenya, Paul Akpejeluh
School of Natural Resources: Dissertations, Theses, and Student Research
Pastoralism has long supported livelihoods and provided essential ecosystem services in landscapes of East Africa. Vegetation productivity is central to the functioning of pastoral systems but may be affected by changes in climate and landuse. Vegetation monitoring is important for understanding the effects of global change in pastoral lands; however, it can be time and resource intensive. Remote sensing provides opportunities for efficient multi-scale monitoring of vegetation and climatic drivers. In this thesis, I explore the utility of satellite and UAV remote sensing for monitoring vegetation and precipitation trends and relationships in the East of Lake Turkana Region of northern …
The Impacts Of Embryo Development And Asynchronous Hatching On Morphology, Growth, And Development Of Larval Burbot (Lota Lota)., Andrew J. Shapiro
The Impacts Of Embryo Development And Asynchronous Hatching On Morphology, Growth, And Development Of Larval Burbot (Lota Lota)., Andrew J. Shapiro
All NMU Master's Theses
Burbot (Lota lota) are native fish in Lake Superior and typically spawn during the winter under the ice or by migrating up rivers. The early life history of larval burbot, where they dispurse, how fast they develop, and what their survival rates have not been extensively studied. Asynchronous hatching is a strategy used by other cod species as a bet-hedging strategy to ensure that some larvae are hatched in more advantageous conditions in a varying environment. Asynchronous hatching has been documented in burbot, but the extent of the period and the impacts that asynchrony has on the development of …

United States Department of Agriculture Wildlife Services: Staff Publications
Investigating the influences of single nucleotide polymorphisms (SNP) associated with conceptus death (CD) on day 16 of pregnancy could distinguish cows who have inferior value for fertility traits. We hypothesized that CD is associated with SNP genotypes that disrupt maternal recognition and lead to early pregnancy loss. RNA sequences from Holstein cow pregnancies (n = 15) with normal conceptuses (Norm) or CD were subjected to SNP discovery via Qiagen CLC Genomics Workbench. Selected SNP were based on previous fertility studies, differentially expressed genes within pregnancy development analyses and proximity to SNP associated with fertility traits in the Cattle QTL …

Students' Attitudes Towards Animals Influences Youth Development Constructs Based On Interactions With Different Animal Species Prior To College, Allison K. Pachunka
Department of Animal Science: Dissertations, Theses, and Student Research
Human-animal interactions (HAI) are commonplace in society and play a consequential role in a variety of situations such as companion animal ownership, agriculture, or youth programs such as 4-H or FFA. Interacting with animals has been shown to provide developmental benefits to children. Positive youth development (PYD), measured by the Five Cs Model, is a framework that focuses on fostering youth’s potential through positive activities which has been studied specifically in 4-H. However, this framework has not been applied to other organizations such as the National FFA Organization (FFA) or to other young adults with less formal interactions with animals. …

Anthropology Faculty Publications
Among human and nonhuman primates, mutual eye gaze (MEG) and gaze following are believed to be important for social cognition and communicative signaling. The goals of this study were to examine how early rearing experiences contribute to individual variation in MEG and to examine the potential role of genetic factors underlying this variation. Subjects included 93 female and 23 male baboons (Papio anubis) ranging from 3 to 20 years of age. Within the sample, there were 55 mother-reared (MR) and 61 nursery-reared (NR) baboons. MEG was assessed in four 60-s test sessions. For each session, the duration, frequency, and bout …
An Analysis Of Plant Response To Herbivory, Lawrence Gustavo Seminario-Romero
An Analysis Of Plant Response To Herbivory, Lawrence Gustavo Seminario-Romero
Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–
Herbivory is often believed to always negatively affect the growth of plants, but there are plant species that can actually benefit from being consumed by herbivores. These plants have a phenotypic trait known as “compensatory growth.” A plant that exhibits compensatory growth is able to increase its intrinsic growth rate as a response to taking damage caused by herbivory, and as a result, produce more biomass. Very few mathematical models used to describe plant-herbivore interactions have accounted for plant compensatory growth. Moreover, these models tend to assume that herbivores follow a Holling type II functional response, which may not necessarily …

Skin Lipids Alone Enable Conspecific Tracking In An Invasive Reptile, The Argentine Black And White Tegu Lizard (Salvator Merianae), M. Rockwell Parker, Eric A. Tillman, Lauren A. Nazarian, Megan L. Barlowe, Julianna M. Lincoln, Bryan M. Kluever
United States Department of Agriculture Wildlife Services: Staff Publications
Locating potential mates in non-native habitats is one of the most important challenges faced by invasive vertebrate species. The Argentine black and white tegu lizard (Salvator merianae) is a major invasive reptile species in the contiguous United States and is rapidly expanding its range across Florida and the Southeast, in part due to inadequate management strategies and tools. Because a wide array of reptiles, especially squamates (snakes and lizards), have been well-studied for their reliance on chemical cues to locate conspecifics, our project aimed to isolate chemical cues from tegus and assess the ability of adult males and …

Workshop Abstracts: The International Conference & Workshop On Lobster (And Crab) Biology And Management, Department Of Primary Industries And Regional Development, Western Australia, Western Rock Lobster Council, Fisheries Research And Development Corporation
International Conference on Lobster (and Crab) Biology and Management (ICWL)
The theme of the 12th ICWL is ‘ecosystem-based fisheries management (EBFM)’. EBFM is a holistic approach to fisheries management that recognises all the interactions within an ecosystem rather than considering a single species or issue in isolation. We consider this represents best practice for fisheries management and reflects that fisheries research and management focus is now broader than just sustainability. Therefore, in addition to presentations that focus on lobster (and crab) biology and stock assessment, we have also welcomed presentations that examine other aspects of EBFM, such as ecosystem effects of fishing, economic assessments, social issues, governance, and compliance with …

Our understanding of the limits of animal life is continually revised by scientific exploration of extreme environments. Here we report the discovery of mummified cadavers of leaf-eared mice, Phyllotis vaccarum, from the summits of three different Andean volcanoes at elevations 6,029–6,233 m above sea level in the Puna de Atacama in Chile and Argentina. Such extreme elevations were previously assumed to be completely uninhabitable by mammals. In combination with a live-captured specimen of the same species from the nearby summit of Volcán Llullaillaco (6,739 m),1 the summit mummies represent the highest altitude physical records of mammals in the …

Killing animals has been a ubiquitous human behaviour throughout history, yet it is becoming increasingly controversial and criticised in some parts of contemporary human society. Here we review 10 primary reasons why humans kill animals, discuss the necessity (or not) of these forms of killing, and describe the global ecological context for human killing of animals. Humans historically and currently kill animals either directly or indirectly for the following reasons: (1) wild harvest or food acquisition, (2) human health and safety, (3) agriculture and aquaculture, (4) urbanisation and industrialisation, (5) invasive, overabundant or nuisance wildlife control, (6) threatened species conservation …

Understanding Functional Benefits Of Isoleucine And Arginine On Poultry Performance And Health., Roshan Adhikari, Jason T. Lee, Keith Haydon
Proceedings of the Arkansas Nutrition Conference
Poultry industry is rapidly moving towards utilizing the best ingredients to precisely feed the birds for better performance, welfare, health, and profitability. One of the practices that evolved over time with research is better optimization of amino acid utilization in the diets thus changing the crude protein landscape. Historically, if we compare the modern diets to diets from 1980, significant changes are visible in the use of unbound or crystalline amino acids leading to reduced levels of CP and reduced unutilized nitrogen in the diets. Multiple feed-grade amino acids are available in a cost-effective manner in poultry diets. Multiple research …

Cold stimulation dynamically remodels mitochondria in brown adipose tissue (BAT) to facilitate non-shivering thermogenesis in mammals, but what regulates mitochondrial plasticity is poorly understood. Comparing mitochondrial proteomes in response to cold revealed FAM210A as a cold-inducible mitochondrial inner membrane protein. An adipocyte-specific constitutive knockout of Fam210a (Fam210aAKO) disrupts mitochondrial cristae structure and diminishes the thermogenic activity of BAT, rendering the Fam210aAKO mice vulnerable to lethal hypothermia under acute cold exposure. Induced knockout of Fam210a in adult adipocytes (Fam210aiAKO) does not affect steady-state mitochondrial structure under thermoneutrality, but impairs cold-induced mitochondrial remodeling, leading to progressive loss of cristae and reduction of …

Habitat loss is a key factor in the ongoing freshwater biodiversity crisis. A promising way to help tackle the rapid decline in freshwater biodiversity is to improve the potential for artificial wetlands to provide habitat for aquatic wildlife. Farm dams (also known as agricultural ponds) are among the most abundant waterbodies in agricultural landscapes and can act as “oases” against droughts for many species. Despite their prominent role in agriculture, predictive models to evaluate their ecological potential are yet to emerge. Here we use a continental-scale data set of 104,013 audio recordings from citizen scientists to identify and locate 107 …
