Humans May Be Unique And Superior — And That Is Irrelevant, Eze Paez 2019 University of Minho

Humans May Be Unique And Superior — And That Is Irrelevant, Eze Paez

Animal Sentience

Chapman & Huffman argue that, because humans are neither unique nor superior to the other animals, cruelty to animals is not justified. Though I agree with their conclusion, I do not think their argument works. Many human beings do have some capacities that animals do not have and are greater in some respects, in the sense of having superior abilities. It is a better argument to deny that any of that is morally relevant. Sentience suffices for moral consideration, and for deriving a moral duty not to harm other animals and to assist them when they are in need.

Phooey On Comparisons, Gwen J. Broude

Animal Sentience

Chapman & Huffman reject the notion that human beings are very different from other animals. The goal is to undermine the claim that human uniqueness and even superiority are reason enough to treat other animals badly. But evaluating human uniqueness for this purpose only plays into the hands of those who exploit invidious comparisons between us and other animals to justify mistreatment of the rest of the animal kingdom. What human uniqueness we may discover would still be no justification for how we behave toward other animals. We should also ask ourselves whether any human-centric criterion can be justification for determining ...


Range Expansion Or Range Shift? Population Genetics And Historic Range Data Analyses Of The Predatory Benthic Sea Slug Phidiana Hiltoni (Mollusca, Gastropoda, Nudibranchia), Clara Jo King, Ryan Ellingson, Jeffrey H. R. Goddard, Rebecca F. Johnson, Angel A. Valdes 2019 California State Polytechnic University, Pomona

Range Expansion Or Range Shift? Population Genetics And Historic Range Data Analyses Of The Predatory Benthic Sea Slug Phidiana Hiltoni (Mollusca, Gastropoda, Nudibranchia), Clara Jo King, Ryan Ellingson, Jeffrey H. R. Goddard, Rebecca F. Johnson, Angel A. Valdes

Bulletin of the Southern California Academy of Sciences

Phidiana hiltoni is a conspicuous nudibranch sea slug native to the northeastern Pacific Ocean. Over the past thirty years the range of P. hiltoni has expanded about 200 km northward, but the mechanism that facilitated this expansion is poorly understood. In this study, we use mtDNA and microsatellite data to investigate the population structure of P. hiltoni in its historical range as well as in recently colonized localities. Microsatellite analyses reveal little to no genetic structure and thus high gene flow throughout the range of P. hiltoni. This is consistent with mtDNA analysis results, which revealed shared haplotypes between Southern ...


Additional Information On A Nonnative Whiptail Population (Aspidoscelis Flagellicauda/Sonorae Complex) In Suburban Orange County, California, Richard A. Erickson, Weston G. Burt 2019 San Diego Natural History Museum

Additional Information On A Nonnative Whiptail Population (Aspidoscelis Flagellicauda/Sonorae Complex) In Suburban Orange County, California, Richard A. Erickson, Weston G. Burt

Bulletin of the Southern California Academy of Sciences

A nonnative population of all-female spotted whiptails from the Asidoscelis flagellicauda/sonorae complex was reported from suburban Irvine, Orange County in 2015 and 2016. We report additional suburban observations dating back to 2010 from Laguna Woods and extending the range south ~6 km southwest to Aliso Viejo. We hope that this and other exotic reptile species will remain restricted to highly altered urban environments and not threaten native species in natural habitats.

Fish Growth Changes Over Time In A Midwestern Usa Lake, Eric D. Katzenmeyer, Michael E. Colvin, Timothy W. Stewart, Clay L. Pierce, Scott E. Grummer

Natural Resource Ecology and Management Publications

Growth of Walleye Sander vitreus, Yellow Bass Morone mississippiensis, Common Carp Cyprinus carpio, and Black Bullhead Ameiurus melas was assessed in Clear Lake, Iowa, USA, over several decades and in relation to environmental variables. Growth of Common Carp was positively correlated with phytoplankton concentration. Recent Black Bullhead growth was faster than in the 1950s and 1990s, which may be a consequence of their recent decline in abundance. Growth of Common Carp and Yellow Bass was faster in the 1940s than in more recent time periods. Relative to their entire range, Common Carp first year growth was below average whereas length ...


An Ecological Niche Model To Predict Range Expansion Of The Eastern Gray Squirrel In California, Carly M. Creley, Alan Muchlinski, Fraser Shilling 2019 California State University, Los Angeles

An Ecological Niche Model To Predict Range Expansion Of The Eastern Gray Squirrel In California, Carly M. Creley, Alan Muchlinski, Fraser Shilling

Bulletin of the Southern California Academy of Sciences

The eastern gray squirrel, Sciurus carolinensis (EGS) has been introduced to California and has expanded its geographic range since initial introductions. In this study we projected the potential future geographic range of the EGS in California using Maxent to create an ecological niche model. Location data were obtained over the time period of 2004 - 2015 from museum specimens, wildlife rehabilitation centers, the California Department of Public Health, the California Roadkill Observation System, and non-iNaturalist citizen science observations. Research grade data from iNaturalist was obtained over the time period of 2004 - 2018. Range and habitat suitability maps were developed by mapping ...


Effect Of Group Size On The Activity Budget Of Two Captive Chimpanzees (Pan Troglodytes), Kaeley Sullins 2019 Central Washington University

Effect Of Group Size On The Activity Budget Of Two Captive Chimpanzees (Pan Troglodytes), Kaeley Sullins

All Master's Theses

Captive facilities housing chimpanzees are required to provide adequate care and provisions such as dietary, social, and environmental enrichment to promote the psychological well-being of the apes in their care. Chimpanzees are social creatures and changes in groups as well as relocation to a facility with new social partners, can impact each individual chimpanzee’s welfare. By tracking each chimpanzee’s activity budgets, managers can assess welfare and make improvements or adjustments if necessary. I looked at the activity budgets of two captive chimpanzees after the death of a group member and the two chimpanzees’ subsequent relocation to a novel ...


Population Viability And Connectivity Of The Federally Threatened Eastern Indigo Snake In Central Peninsular Florida, Javan Bauder 2019 University of Massachusetts Amherst

Population Viability And Connectivity Of The Federally Threatened Eastern Indigo Snake In Central Peninsular Florida, Javan Bauder

Doctoral Dissertations

Understanding the factors influencing the likelihood of persistence of real-world populations requires both an accurate understanding of the traits and behaviors of individuals within those populations (e.g., movement, habitat selection, survival, fecundity, dispersal) but also an understanding of how those traits and behaviors are influenced by landscape features. The federally threatened eastern indigo snake (EIS, Drymarchon couperi) has declined throughout its range primarily due to anthropogenically-induced habitat loss and fragmentation making spatially-explicit assessments of population viability and connectivity essential for understanding its current status and directing future conservation efforts.

The primary goal of my dissertation was to understand how ...


The Effect Of Cow Udder Score On Subsequent Calf Performance In The Nebraska Sandhills, Joslyn K. Beard, Jacki A. Musgrave, Rick N. Funston Funston, J. Travis Mulliniks 2019 University of Nebraska - Lincoln

The Effect Of Cow Udder Score On Subsequent Calf Performance In The Nebraska Sandhills, Joslyn K. Beard, Jacki A. Musgrave, Rick N. Funston Funston, J. Travis Mulliniks

Nebraska Beef Cattle Reports

Cow records were evaluated over a 5-yr period to investigate how cow udder score affected calf growth and carcass performance. Cows from 2 calving herds, March and May, were classified as bad or good based on udder scores recorded at calving. Calves suckling dams with bad udders performed similarly during the pre-weaning period to good udder counterparts, with no differences in overall steer feedlot performance between udder groups. However, steers suckling good udder cows had heavier carcass weights and greater back fat thickness.


Effects Of Backgrounding And Feedlot System Strategies On May-Born Steer Performance, Alicia C. Lansford, Jacki A. Musgrave, T. L. Meyer Meyer, Rick N. Funston 2019 University of Nebraska–Lincoln

Effects Of Backgrounding And Feedlot System Strategies On May-Born Steer Performance, Alicia C. Lansford, Jacki A. Musgrave, T. L. Meyer Meyer, Rick N. Funston

Nebraska Beef Cattle Reports

May-born steers were backgrounded to achieve either a high or low rate of gain. The high rate of gain was achieved by offering steers meadow hay ad libitum and 4 lb/d of a 33% CP (DM) supplement, while the low rate of gain consisted of steers grazing meadow and offered 1 lb/d of the same supplement. After backgrounding, one-half of the steers from each group entered the feedlot in May as short-yearlings, while the remainder grazed upland range until entering the feedlot as long-yearlings in mid-September. Hot carcass weight was greater for steers backgrounded to achieve a high ...


Effects Of Isolated Nutrients In Distillers Grains On Total Tract Digestibility And Digestible Energy In Forage Diets, Tasha M. King, Melissa L. Jolly-Breithaupt, Hannah C. Hamilton Hamilton, Galen E. Erickson, Jim C. MacDonald 2019 University of Nebraska - Lincoln

Effects Of Isolated Nutrients In Distillers Grains On Total Tract Digestibility And Digestible Energy In Forage Diets, Tasha M. King, Melissa L. Jolly-Breithaupt, Hannah C. Hamilton Hamilton, Galen E. Erickson, Jim C. Macdonald

Nebraska Beef Cattle Reports

A digestion study was conducted to evaluate the contribution of individual nutrient components of distillers grains on nutrient digestibility and digestible energy. All diets contained 56% brome hay with a control diet containing either 40% corn; or 40% modified distillers grains. Four additional diets compared the contribution of fat, protein, fiber, and solubles components of distillers grains. No differences were observed for digestibility of DM, OM, and NDF among treatments. Feeding the isolated protein resulted in similar digestible energy to modified distillers grains, suggesting the bypass protein component contributes heavily to energy in distillers.


Confined Cow-Calf Production System And Post-Weaning Management Impact On Calf Production, Shelby E. Gardine, Brad M. Boyd, F. Henry Hilscher Hilscher, Galen E. Erickson, Karla H. Jenkins, Andrea K. Watson, Terry J. Klopfenstein 2019 University of Nebraska-Lincoln

Confined Cow-Calf Production System And Post-Weaning Management Impact On Calf Production, Shelby E. Gardine, Brad M. Boyd, F. Henry Hilscher Hilscher, Galen E. Erickson, Karla H. Jenkins, Andrea K. Watson, Terry J. Klopfenstein

Nebraska Beef Cattle Reports

Calf performance was measured in a 3-yr study with a 2 × 2 factorial treatment design: 1) cow-calf production system (dry lot feeding or grazing corn residue) and 2) directly finishing calves or growing prior to finishing. Calves wintered on cornstalks were lighter at weaning than calves wintered in the dry-lot. However, following the finishing period, there were no effects of pre-weaning production system on final body weight or hot carcass weight. Calves directly adapted to a finishing diet had greater gain and improved efficiency compared to calves fed a grower diet prior to finishing. However, calves that were grown first ...

Nebraska Beef Cattle Reports

The University of Nebraska (UNL) Gudmundsen Sandhills Laboratory (GSL) is a 12,800-acre research ranch in the Nebraska Sandhills. In 1978, Elmer “Pete” and Abbie Gudmundsen gifted the former Rafter C Ranch to the University of Nebraska Foundation. Thus, 2018 was the 40th year of UNL oversight of GSL. To the credit of UNL Administration, GSL development for range livestock research was delegated to a team of Research and Extension Specialists chaired by Dr. Don Clanton. Other members of that original team were Jim Nichols, Range Science; Gene Deutscher, Reproductive Physiologist; Dick Clark, Agricultural Economist; and Ivan Rush, Beef Extension ...


Evaluation Of Fractionated Distillers Grains (High Protein And Bran Plus Solubles) On Performance And Carcass Characteristics In Finishing Diets, Shelby A. Garland, Bradley M. Boyd, F. Henry Hilscher Hilscher, Galen E. Erickson, Jim C. MacDonald, Ryan A. Mass 2019 University of Nebraska-Lincoln

Evaluation Of Fractionated Distillers Grains (High Protein And Bran Plus Solubles) On Performance And Carcass Characteristics In Finishing Diets, Shelby A. Garland, Bradley M. Boyd, F. Henry Hilscher Hilscher, Galen E. Erickson, Jim C. Macdonald, Ryan A. Mass

Nebraska Beef Cattle Reports

A finishing study evaluated the effect of feeding a new, high protein distillers grains along with corn bran plus condensed distillers solubles compared to traditional wet distillers grains, traditional dry distillers grains and a corn-based control. Each byproduct replaced corn at 40% of the diet dry-matter. Intake was not affected by treatment; however gain and carcass weight were greater and feed conversion improved for high protein distillers and corn bran plus solubles than either type of traditional distillers grains or corn. Based on feed efficiency, the feeding values of high protein distillers grains and corn bran plus solubles are 121 ...


Evaluation Of Corn Bran Plus Solubles On Performance And Carcass Characteristics In Finishing Diets, Shelby A. Garland, Bradley M. Boyd, F. Henry Hilscher Hilscher, Galen E. Erickson, Jim C. MacDonald, Ryan A. Mass 2019 University of Nebraska-Lincoln

Evaluation Of Corn Bran Plus Solubles On Performance And Carcass Characteristics In Finishing Diets, Shelby A. Garland, Bradley M. Boyd, F. Henry Hilscher Hilscher, Galen E. Erickson, Jim C. Macdonald, Ryan A. Mass

Nebraska Beef Cattle Reports

A finishing study was conducted to determine the effect of feeding corn bran plus solubles, a new feed resulting from a pre-fermentation fiber removal process, compared to wet distillers grains plus solubles at two levels of inclusion (20% and 40% of diet DM). Intake increased with inclusion of byproduct, and steers fed 20% wet distillers had the greatest intakes numerically. Byproduct inclusion, regardless of type, increased daily gain over the corn-based control. Feed conversions were improved with increased inclusion of both Bran + Solubles and wet distillers, and both were superior to the control. Increased inclusion of both byproducts resulted in ...


Prediction Of Energy Value (Tdn) In Grazed And Hayed Forages, Terry J. Klopfenstein, Mary E. Drewnoski, Karla H. Jenkins Jenkins 2019 University of Nebraska - Lincoln

Prediction Of Energy Value (Tdn) In Grazed And Hayed Forages, Terry J. Klopfenstein, Mary E. Drewnoski, Karla H. Jenkins Jenkins

Nebraska Beef Cattle Reports

The goal of producers and nutritionists is to meet the nutritional needs of their cattle. Requirements are well established, but the diets of grazing cattle are difficult to predict. Selection by the animal, sample handling, lab analysis, and relating the lab analysis to the animal are issues that have been researched the last 20 years. Based on that research, data have been compiled to predict the energy and protein values of grazed Sandhills range, meadows, smooth brome, and corn residue. Additionally, equations used by commercial labs to predict the TDN of grass hays based on ADF were compared to TDN ...
