Stress And Reproductive Hormones Reflect Inter-Specific Social And Nutritional Conditions Mediated By Resource Availability In A Bear–Salmon System, Heather M. Bryan, Chris T. Darimont, Paul C. Paquet, Katherine E. Wynne-Edwards, Judit E. G. Smits

Physiology Collection

Food availability can influence the nutritional and social dynamics within and among species. Our investigation focused on grizzly and black bears in coastal British Columbia, Canada, where recent and dramatic declines in their primary prey (salmon) raise concerns about potentially negative effects on bear physiology. We examined how salmon availability relates to stress and reproductive hormones in coastal grizzly (n = 69) and black bears (n = 68) using cortisol and testosterone. In hair samples from genotyped individuals, we quantified salmon consumption using stable isotope analysis and hormone levels by enzyme immunoassay. To estimate the salmon biomass available to each …

The History And Reintroduction Of Whooping Cranes At White Lake Wetlands Conservation Area, Louisiana, Gay M. Gomez

Proceedings of the North American Crane Workshop

On 16 February 2011, whooping cranes (Grus americana) were reintroduced in the wetlands of southwest Louisiana, after an absence of 61 years. This brief communication provides background on the historical presence of whooping cranes in this region, describes the long road to reintroduction, presents observations from the reintroduction’s first day, and offers thoughts on its future prospects.

On 15 May 1939, biologist John J. Lynch of the U.S. Fish and Wildlife Service observed 13 whooping cranes in the remote freshwater marsh north of White Lake in Vermilion Parish, Louisiana. He not only confirmed what local residents and trappers had long …

Frequency-Dependent Mate Selection In The Guppy (Poeciliidae: Poecilia Reticulata), Andre Porter, Jack Frankel

Department of Biology Faculty Publications

Heterogeneity within a population enhances its long-term survival. A fundamental method of maintaining population heterogeneity is the retention of rare or uncommon phenotypes by selective mating strategies. Employing two color morphs, red tuxedo and red, of the guppy (Poecilia reticulata, Poeciliidae), this study was designed to investigate whether P. reticulata females would preferentially seek out heterogeneous groupings of males exhibiting two color morphs. Adult female guppies were exposed simultaneously to two groups of males (n=10); one comprised of only the tuxedo color morph (n=5) and the other of both color morphs (n=5). For the latter group, the ratio of males …

Assessing And Managing Freshwater Ecosystems Vulnerable To Environmental Change, David G. Angeler, Craig R. Allen, Hannah E. Birgé, Stina Drakare, Brendan G. Mckie, Richard K. Johnson

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Freshwater ecosystems are important for global biodiversity and provide essential ecosystem services. There is consensus in the scientific literature that freshwater ecosystems are vulnerable to the impacts of environmental change, which may trigger irreversible regime shifts upon which biodiversity and ecosystem services may be lost. There are profound uncertainties regarding the management and assessment of the vulnerability of freshwater ecosystems to environmental change. Quantitative approaches are needed to reduce this uncertainty. We describe available statistical and modeling approaches along with case studies that demonstrate how resilience theory can be applied to aid decision-making in natural resources management. We highlight especially …

Effects Of River Current Inflow On Dissolved Oxygen And Temperature Of Refuge Zones For Cisco In Lake Bemidji, Bryant C. Swenson

Journal of Earth and Life Science

The objectives of this study were to (1) determine if the inflow current from the Mississippi River affects temperature and dissolved oxygen in Lake Bemidji, (2) determine how the amount of suitable cisco Coregonus artedi habitat changes over the summer in Lake Bemidji, and (3) predict how much cisco habitat would be available under a climate warming scenario. Summer fish kill of cisco occurs in most years on Lake Bemidji resulting from low dissolved oxygen in the hypolimnion and high water temperatures in the epilimnion. Dissolved oxygen and temperature profiles provided evidence to suggest the north basin is more suitable …

The Effect Of Barometric Pressure On Feeding Activity Of Yellow Perch, Daniel Vanderweyst

Journal of Earth and Life Science

This is the first study to our knowledge that has attempted to relate feeding activity of fish to barometric pressure. This study was conducted with the expectation that a difference in food ingestion would occur in a game fish species at different barometric pressures. The overall objective of this study is to determine if barometric pressure influences the feeding activity of a popular game fish. Yellow perch (Perca flavescens) were collected by seine and trap net from Lake Bemidji 12 September through 24 October 2013. The range in size and weight of yellow perch used for this study …

Use Of Cast Nets And Seine Hauls To Estimate Abundance Of Age-0 Yellow Perch, Michael Vaske

Journal of Earth and Life Science

Knowledge about fish population dynamics is essential for developing management plans and evaluating management success. In many lakes, yellow perch (Perca flavescens) are the main forage for many upper level predators and recreational fish species. To better manage recreational fisheries, an accurate estimate of prey abundance is necessary. The objectives of the study were to sample the littoral and limnetic zone to better estimate population of age-0 yellow perch, and obtain an estimate of the proportion of yellow perch being missed by traditional littoral seining methods. Littoral seines were conducted at three randomly selected locations in the south …

Journal of Earth and Life Science

The objective of this study was to determine if walleye Sander vitreus percent dry weight, a measure of condition, differed among summer months of 2014 on Maple Lake, Minnesota. A second objective was to determine if there was a relationship between condition and body temperature, total length, or wet weight. Between three and six walleyes were collected per month by hook and line methods. All fish had internal body temperatures taken at the time of capture and were oven dried in the laboratory at 80 °C in order to measure percent dry weight. There was no relationship between condition and …

Protein 14-3-3 (Ywha) Isoforms And Their Roles In Regulating Mouse Oocyte Maturation, Santanu De

Biology Faculty Books and Book Chapters

The 14-3-3 (YWHA) is a highly conserved, ubiquitously expressed protein family regulating important cellular processes including cell cycle. This work, for the first time, explored the differential expression and roles of 14-3-3 isoforms during mouse oocyte maturation.

All seven mammalian 14-3-3 isoforms were identified in mouse eggs and ovarian follicular cells including oocytes, by Western blotting. Immunocytochemical and immunohistochemical staining confirmed the presence of all 14-3-3 isoforms in oocytes, eggs and ovarian follicles with characteristic similarities and differences in their distributions.

Mammalian oocytes are arrested at meiosis prophase I by an inhibitory phosphorylation on Cyclin-Dependent Kinase I (CDK1), released by …

The Effects That Liquid And Solid Cattle Manure Have On The Water Quality Of Drainage Ditches In Putnam County, Ohio, Janelle Horstman

Honors Projects

Lake Erie has experienced harmful algal blooms with increased frequency since the mid-1990s due to excess nutrients from Rivers, such as the Maumee River, and largely agricultural watersheds. Nonpoint source pollution from agriculture contributes to eutrophication, algal blooms, and the degradation of water quality. This creates stress on aquatic fauna, reduced aesthetic quality, odor, and limits of the water for usage of drinking, recreation, and industry. This research paper asks what the contributions of having access to manure application records, soil records, and information about antibiotics have on what is known about manure management and antibiotic resistance, which has been …

Economics Of Distillers Grains Supplementation In A Forage System With Spayed Heifers, Kari L. Gillespie, Terry J. Klopfenstein, James C. Macdonald Donald, Brandon L. Nuttelman, Cody J. Schneider, Galen Erickson, J. D. Volesky

Nebraska Beef Cattle Reports

In a two-year study, spayed heifer calves were backgrounded on cornstalks with 2 lb or 5 lb wet distillers grains with solubles supplemented daily. During the summer, heifers grazed native range and received no summer supplementation or were supplemented with modified distillers grains with solubles at 0.6% BW daily. Heifers were finished on a common regimen, and an economic scenario was applied to each phase of production and overall. Supplementing more in winter increased profit, but summer supplementation did not impact overall profitability. Numerically, heifers not supplemented during the summer were more profitable than supplemented heifers.

Effect Of Winter Supplementation Level On Yearling System Profit Across Economic Scenarios, Kari L. Gillespie, Terry J. Klopfenstein, James C. Macdonald Donald, Brandon L. Nuttelman, Cody J. Schneider

Nebraska Beef Cattle Reports

Calves backgrounded in a forage–based, yearling system at a greater ADG maintained a performance advantage through finishing. High-level supplemented cattle gained an additional 0.18 lb daily during finishing and produced an additional 81 lb of saleable live weight compared to cattle backgrounded at a low-supplementation level. Across four economic scenarios with varying corn and distillers prices, high-level supplemented cattle returned $55.54 more than cattle fed a low level of supplementation during the winter backgrounding phase. Corn price would have to exceed $11.70/bu for high supplementation level to no longer be profitable.

Effects Of Calf Age At Weaning On Cow And Calf Performance And Efficiency In A Drylot/Confinement Production System, Jason M. Warner, Karla H. Jenkins, Rick J. Rasby, Matt K. Luebbe, Galen E. Erickson, Terry J. Klopfenstein

Nebraska Beef Cattle Reports

An ongoing study evaluated the effectsof calf age at weaning on cow and calf performance and reproduction in a confinement production system. Early-weaning improved cow BW at normal weaning. Pregnancy rates were not impacted by calf age at weaning. Dry matter intake was not different between early-weaned cows and calves compared with normal-weaned pairs. Feed requirements and energy utilization were equal between early- and normal-weaned pairs when fed a distillers grains and crop residue based diet.

Effects Of Dietary Change On Viral-Bacterial Interactions In The Rumen Of Cattle, Christopher L. Anderson, Melissa L. Jolly, Adam L. Shreck Shreck, Galen E. Erickson, Terry J. Klopfenstein, Samodha C. Fernando

Nebraska Beef Cattle Reports

This ongoing study investigates the impact of diet and bacteriophage activity on the structuring of rumen microbial community composition and diversity. Fistulated cattle were acclimated to a given diet for 21 days before samples were collected and subsequently enriched for viral particles with tangential flow filtration. Taxonomic identification, abundance, and functional attributes were assigned to both bacterial and viral communities. Principle coordinate analysis of the bacterial communities revealed significant clustering based on diet. While diet drives the structuring of rumen bacterial communities, bacteriophages may maintain high, constant bacterial diversity.

The Short-Term Effects Of A Routine Poisoning Campaign On The Movements And Detectability Of A Social Top-Predator., B L. Allen, R. M. Engeman, L. K-P. Leung

United States Department of Agriculture Wildlife Services: Staff Publications

Top-predators can be important components of resilient ecosystems, but they are still controlled in many places to mitigate a variety of economic, environmental and/or social impacts. Lethal control is often achieved through the broadscale application of poisoned baits. Understanding the direct and indirect effects of such lethal control on subsequent movements and behaviour of survivors is an important pre-requisite for interpreting the efficacy and ecological outcomes of top predator control. In this study, we use GPS tracking collars to investigate the fine-scale and short-term movements of dingoes (Canis lupus dingo and other wild dogs) in response to a routine poison-baiting …

A Revision Of The Octocoral Genus Ovabunda Alderslade, 2001 (Anthozoa, Octocorallia, Xeniidae), Catherine S. Mcfadden, Yehuda Benayahu, Anna Halász, Dafna Aharonovich, Robert Toonen

All HMC Faculty Publications and Research

The family Xeniidae (Octocorallia) constitutes an abundant benthic component on many Indo-West Pacific coral reefs and is ecologically important in the Red Sea. The genus Ovabunda Alderslade, 2001 was recently established to accommodate previous Xenia species with sclerites comprised of a mass of minute corpuscle-shaped microscleres. The aim of the present study was to examine type material of Xenia species in order to verify their generic affiliation. We present here a comprehensive account of the genus Ovabunda, using scanning electron microscopy to depict sclerite microstructure. We assign three Xenia species to the genus: O. ainex comb. n., O. …
