Management Of Wintering Short-Eared Owls At Airports In The Lower Great Lakes Region, Aaron Bowden, Robert J. Hromack, Christopher H. Loftis, Aaron D. Spencer, Brian E. Washburn

Wildlife Damage Management Conference

USDA Wildlife Services airport wildlife biologists have been tasked with reducing the hazards that raptors (including owls) pose to safe aircraft operations at airports and military airfields throughout the USA. A review of available wildlife strike information suggests short-eared owls (Asio flammeus) are frequently struck by aircraft during the winter months at numerous airports within the Lower Great Lakes Region of the United States. Further, this species is listed as ‘endangered’ by state fish and wildlife agencies in many states, although not at the federal level. Consequently, there is particular interest in developing non-lethal management tools for reducing the hazards …

International Journal of Exercise Science

International Journal of Exercise Science 10(2): 205-212, 2017 Engaging in a physically active lifestyle relates positively to current health and reduces chances of chronic diseases in the future. Given escalating health care costs, it is paramount to reduce illnesses associated with a lack of physical activity and thus critical to identify factors that influence physical activity - especially in children, with the opportunity for a lifetime impact. One of these influencing factors may be parents/guardians. The intent of this study was to examine the relationship between children’s physical activity levels and parental factors including parental physical activity, support/encouragement, restrictiveness, and …

Aerobic Capacity Is Related To Repeated Sprint Ability With Sprint Distances Less Than 40 Meters., Gabriel J. Sanders, Zachary Turner, Brian Boos, Corey Peacock, Willard Peveler, Alar Lipping

International Journal of Exercise Science

International Journal of Exercise Science 10(2): 197-204, 2017 Research is inconclusive regarding the association between aerobic fitness (objectively measured VO_2max) and repeated sprint performance when the sprints are less than 40 meters. Soccer athletes must be able to repeat sprints without significant decreases in speed and strength and conditioning coaches need to better understand if aerobic fitness is related to repeated sprint ability (RSA). Twenty (10 male, 10 female) Division I soccer athletes first completed a graded maximal treadmill test to measure VO_2max. Then on a separate day, athletes completed the RSA test. The RSA test …

An Acute Bout Of A Controlled Breathing Frequency Lowers Sympathetic Neural Outflow But Not Blood Pressure In Healthy Normotensive Subjects, Shannon Mcclain, Alexa Brooks, Sara Jarvis

International Journal of Exercise Science

International Journal of Exercise Science 10(2): 188-196, 2017 Controlled or paced breathing is often used as a stress reduction technique but the impact on blood pressure (BP) and sympathetic outflow have not been consistently reported. The purpose of this study was to determine whether a controlled breathing (12 breaths/min, CB) rate would be similar to an individual’s spontaneous breathing (SB) rate. Secondly, would a CB rate of 12 breaths/min alter heart rate (HR), BP, and indices of muscle sympathetic nerve activity (MSNA). Twenty-one subjects (10 women, 11 men) performed two trials: SB, where the subject chose a comfortable breathing rate; …

Autonomic Modulation In Older Women: Using Resistance Exercise As A Countermeasure, Hayden Gerhart, Yu Lun Tai, Curtis Fennell, Xián Mayo, J. Derek Kingsley

International Journal of Exercise Science

International Journal of Exercise Science 10(2): 178-187, 2017 It is unclear if resistance training (RT) can be used to alter declines in autonomic modulation associated with aging. Young women (YW; range 18-25 yrs) and older women (OW; range 50-72 yrs) were compared at baseline. Only OW underwent supervised RT 2 days a week for 12-weeks. Baseline and post-training measurements included heart rate variability (HRV) and complexity (Sample Entropy) to assess autonomic modulation. The 12-weeks of RT consisted of 9 exercises performing 3 sets of 8-12 repetitions. At baseline, group differences in maximal strength, and autonomic modulation were evaluated with a …

Review Of Physical Activity Benefits And Potential Considerations For Individuals With Surgical Fusion Of Spine For Scoliosis, Rumit S. Kakar, Kathy J. Simpson, Bhibha M. Das, Cathleen N. Brown

International Journal of Exercise Science

International Journal of Exercise Science 10(2): 166-177, 2017 Evidence-based recommendations for physical activity following spinal fusion surgeries for idiopathic scoliosis are limited, specifically in the adolescent population. Individuals with scoliosis treated operatively or non-operatively have been reported to participate in less than 1-3 days/week of even mildly strenuous physical exercises. Over 40% of individuals with scoliosis returned to sports at a level lower than pre-operative participation levels or did not return at all post spinal fusion. It is particularly important for human movement specialists, such as physical therapists, occupational therapists, athletic trainers and kinesiologists to assist these individuals effectively transition …

The Role Of Estradiol Metabolism In Urogenital Schistosomiasis-Induced Bladder Cancer, Nuno Vale, Maria Gouveia, Gabriel Rinaldi, Julio Santos, Lucio Lara Santos, Paul J. Brindley, Jose Correia Da Costa

Microbiology, Immunology, and Tropical Medicine Faculty Publications

Urogenital schistosomiasis is a neglected tropical disease that can lead to bladder cancer. How urogenital schistosomiasis induces carcinogenesis remains unclear, although there is evidence that the human blood fluke Schistosoma haematobium, the infectious agent of urogenital schistosomiasis, releases estradiol-like metabolites. These kind of compounds have been implicated in other cancers. Aiming for enhanced understanding of the pathogenesis of the urogenital schistosomiasisinduced bladder cancer, here we review, interpret, and discuss findings of estradiol-like metabolites detected in both the parasite and in the human urine during urogenital schistosomiasis. Moreover, we predict pathways and enzymes that are involved in the production of these …

Pathology Faculty Publications

Trifunctional protein deficiency/Long-chain hydroxyacyl-CoA dehydrogenase deficiency (LCHAD/TFP) deficiency is a disorder of fatty acid oxidation and ketogenesis. Severe neonatal lactic acidosis, cardiomyopathy, and hepatic dysfunction are caused by the accumulation of toxic long-chain acylcarnitines. The feasibility of umbilical cord blood use in screening for acylcarnitine analysis and free carnitine has been hypothesized but not reported in LCHAD/TFP neonates.

We present a 4 week old female who was at risk of inheriting LCHAD/TFP deficiency and was diagnosed at the time of delivery using umbilical cord blood. Umbilical cord blood was collected at delivery and sent for acylcarnitine analysis. Treatment was started …

Competition From Bromus Tectorum Removes Differences Between Perennial Grasses In N Capture And Conservation Strategies, Rebecca E. Drenovsky, Jeffrey T. Walker, J. J. James

Biology

Background and aims

Competition from the annual grass Bromus tectorum threatens aridland perennial bunchgrass communities. Unlike annuals, perennials must allocate part of their first year nitrogen (N) budget to storage rather than growth, potentially placing them at a competitive disadvantage.

Methods

We evaluated N acquisition and conservation for two perennial bunchgrasses, Agropyron desertorum and Pseudoroegneria spicata, at the seedling stage to investigate potential trade-offs between storage and growth when grown with and without B. tectorum under two levels of soil N.

Results

Agropyron desertorum had higher growth rates, N uptake, and N productivity than P. spicata when grown without …

Birth Plan Non-Adherence: Impact On Birth Satisfaction, Interventions And Perceived Birth Trauma, Mollie Berger

Student Research Conference Select Presentations

Birth plans help to empower women in their birth decisions and create a means to communicate with the healthcare providers prior to going into labor. Birth plans play a distinct role in overall birth satisfaction, which in turn has an impact of maternal well-being and bonding with the infant. When changes are made to birth plans, especially without the mother’s consent, overall birth satisfaction may decrease and the risk of developing post- birth traumatic symptoms may increase. An online survey of childbirth experiences was administered to more than 2000 women. Birth satisfaction and post-birth traumatic symptoms were compared between women …

Micrornas, Heart Failure, And Aging: Potential Interactions With Skeletal Muscle, Kevin A. Murach, John J. Mccarthy

Center for Muscle Biology Faculty Publications

MicroRNAs (miRNAs) are small noncoding RNAs that regulate gene expression by targeting mRNAs for degradation or translational repression. MiRNAs can be expressed tissue specifically and are altered in response to various physiological conditions. It has recently been shown that miRNAs are released into the circulation, potentially for the purpose of communicating with distant tissues. This manuscript discusses miRNA alterations in cardiac muscle and the circulation during heart failure, a prevalent and costly public health issue. A potential mechanism for how skeletal muscle maladaptations during heart failure could be mediated by myocardium-derived miRNAs released to the circulation is presented. An overview …

Variable Alkaloid Defenses In The Dendrobatid Poison Frog Oophaga Pumilio Are Perceived As Differences In Palatability To Arthropods, Sarah Bolton, Kelsey Dickerson, Ralph Saporito

2017 Faculty Bibliography

Conspicuously colored dendrobatid frogs sequester alkaloid defenses from dietary arthropods, resulting in considerable alkaloid variation among populations; however, little is known about how variation is perceived as a defense against predators. Previous studies have found variable alkaloids in the dendrobatid Oophaga pumilio to be associated with differences in toxicity to laboratory mice, suggesting variable defenses are important. Arthropods are natural predators that use chemoreception to detect prey, including frogs, and may therefore perceive variation in alkaloid profiles as differences in palatability. The goal of the present study is to determine how arthropods respond to variable alkaloid defenses in O. pumilio. …

Thinking Chickens: A Review Of Cognition, Emotion, And Behavior In The Domestic Chicken, Lori Marino

Intelligence Collection

Domestic chickens are members of an order, Aves, which has been the focus of a revolution in our understanding of neuroanatomical, cognitive, and social complexity. At least some birds are now known to be on par with many mammals in terms of their level of intelligence, emotional sophistication, and social interaction. Yet, views of chickens have largely remained unrevised by this new evidence. In this paper, I examine the peer-reviewed scientific data on the leading edge of cognition, emotions, personality, and sociality in chickens, exploring such areas as self-awareness, cognitive bias, social learning and self-control, and comparing their abilities in …

Fisheries Research Reports

Fishing for the blue swimmer crab, Portunus armatus, represents an iconic Western Australian recreational fishing experience. State-wide integrated surveys of boat-based recreational fishing conducted by the Department of Fisheries, Western Australia (DoF) in 2011/12 and 2013/14 reported that three times more blue swimmer crabs were caught than any other recreational species (Ryan etal., 2013; Ryan et al., 2015).

Spatial And Temporal Dynamics Of Western Australia’S Commercially Important Sharks, Matias Braccini, R. Mcauley, Alastair Harry

Fisheries Research Reports

This project took advantage of an unprecedented deployment of acoustic receiver infrastructure around the Western Australian coast to monitor a large number of sharks implanted with acoustic tags. This research was undertaken to better understand the temporal and spatial dynamics of commercially-important sharks in Western Australia, which has enabled a re-evaluation of the risks of cryptic sources of catch and bycatch to dusky and sandbar shark stocks and development of population simulation models with which to test the implications of spatially-different histories of fishery management, as well as future spatial-management arrangements for whiskery and gummy sharks stocks.

Escape Behaviour Of Aposematic (Oophaga Pumilio) And Cryptic (Craugastor Sp.) Frogs In Response To Simulated Predator Approach, Ralph Saporito

2017 Faculty Bibliography

Crypsis and aposematism are common antipredator strategies that can each be coupled with behaviours that maximize predator deterrence or avoidance. Cryptic animals employ camouflage to conceal themselves within their environment and generally rely on immobility to avoid detection by predators. Alternatively, aposematic animals tend to rely on an association between conspicuous colouration and secondary defence to deter potential predators, and tend to exhibit slow movements in response to predators. The goal of the present study was to determine how cryptic Craugastorsp. and aposematic Oophaga pumilio respond to simulated human and bird model predators. Oophaga pumilio responded more often with movement …

A Method For Independent Component Graph Analysis Of Resting-State Fmri, Demetrius Ribeiro De Paula, Erik Ziegler, Pubuditha M. Abeyasinghe, Tushar K. Das

Anatomy and Cell Biology Publications

Introduction: Independent component analysis (ICA) has been extensively used for reducing task-free BOLD fMRI recordings into spatial maps and their associated time-courses. The spatially identified independent components can be considered as intrinsic connectivity networks (ICNs) of non-contiguous regions. To date, the spatial patterns of the networks have been analyzed with techniques developed for volumetric data. Objective: Here, we detail a graph building technique that allows these ICNs to be analyzed with graph theory. Methods: First, ICA was performed at the single-subject level in 15 healthy volunteers using a 3T MRI scanner. The identification of nine networks was performed by a …
