Bridging The Empathy Gap For Invertebrates, John M. Marzluff Jan 2020

Bridging The Empathy Gap For Invertebrates, John M. Marzluff

Animal Sentience

The actions of sentient vertebrates command our attention and inform our morality. Mikhalevich & Powell (2020) (M&P) argue that similar activities in a wide range of invertebrates with central nervous systems should do likewise. However, humans most readily empathize with creatures we recognize as similar in behavior, physiology, or appearance to ourselves. Helping humanity overcome this bias is a significant challenge for those who study invertebrates. Until this empathy gap is bridged, I believe few people and the policies they craft will afford invertebrates the moral standing that M&P argue they deserve. Therefore, I suggest those interested in raising appreciation …


Obituary: Sydney Anderson (1927–2018), Scott Lyell Gardner, Robert M. Timm, Nancy Olds, Hugh H. Genoways Jan 2020

Obituary: Sydney Anderson (1927–2018), Scott Lyell Gardner, Robert M. Timm, Nancy Olds, Hugh H. Genoways

Scott L. Gardner Publications

On August 12, 2018, the American Society of Mammalogists (ASM) lost one of its giants of the latter half of the 20th century when Sydney Anderson quietly passed away at his home in Birmingham, Alabama, at the age of 91. “Syd,” to his many friends and colleagues, was born on January 11, 1927 in Topeka, Kansas, to Robert Grant and Evelyn Fern (Hunt) Anderson.

Anderson began his professional career at the University of Kansas, where for four years (1955–1959) he served as Assistant Curator in charge of mammals in the Museum of Natural History, and Instructor in the Department of …


Innovative, Yes: But Is It Rewilding?, Daniel T. Blumstein, Kate E. Lynch Jan 2020

Innovative, Yes: But Is It Rewilding?, Daniel T. Blumstein, Kate E. Lynch

Animal Sentience

Baker & Winkler’s extremely stimulating proposal clearly illustrates conflicting priorities in biodiversity conservation and management that are exacerbated when human cultural resources and animal welfare are a part of the solution. We suggest that the discussion can benefit from an even more explicit unpacking of the conflicting values associated with the proposal.


How To Engage Public Support To Protect Overlooked Species, Scarlett R. Howard, Adrian G. Dyer Jan 2020

How To Engage Public Support To Protect Overlooked Species, Scarlett R. Howard, Adrian G. Dyer

Animal Sentience

Treves et al. (2019) propose a non-anthropocentric approach to conservation biology for the ‘just preservation’ of non-humans. Some of our current ways of ranking conservation efforts based on benefits to humans are indeed critically flawed, but we doubt that a completely non-anthropocentric approach is possible at this time. We propose a way to generate public support for those non-human species that may otherwise be overlooked in policy-making and conservation efforts.


Conflicts And Triage, Kate E. Lynch, Daniel T. Blumstein Jan 2020

Conflicts And Triage, Kate E. Lynch, Daniel T. Blumstein

Animal Sentience

To represent diverse interests successfully, a strategy for dealing with conflicts is needed. We discuss an approach to maximizing the interests of the greatest number of individuals, present and future.


Problems With Basing Insect Ethics On Individuals’ Welfare, Susana Monsó, Antonio J. Osuna-Mascaró Jan 2020

Problems With Basing Insect Ethics On Individuals’ Welfare, Susana Monsó, Antonio J. Osuna-Mascaró

Animal Sentience

In their target article, Mikhalevich & Powell (M&P) argue that we should extend moral protection to arthropods. In this commentary, we show that there are some unforeseen obstacles to applying the sort of individualistic welfare-based ethics that M&P have in mind to certain arthropods, namely, insects. These obstacles have to do with the fact that there are often many more individuals involved in our dealings with insects than our ethical theories anticipate, and also with the fact that, in some sense, some insects count as more than an individual and, in another sense, they sometimes count as less than an …


Lessons From Miniature Brains: Cognition Cheap, Memory Expensive (Sentience Linked To Active Movement?), Giorgio Vallortigara Jan 2020

Lessons From Miniature Brains: Cognition Cheap, Memory Expensive (Sentience Linked To Active Movement?), Giorgio Vallortigara

Animal Sentience

Studies on invertebrate minds suggest that the neural machinery for basic cognition is cheap, and that bigger brains are probably associated with greater memory storage rather than more advanced cognition. Sentience may be linked to feedforward mechanisms (Reafferenzprinzip) that allow organisms with active movement to distinguish active and passive sensing. Invertebrates may offer special opportunities for testing these hypotheses.


Fishes Of The Dakotas, Kathryn Schlafke Jan 2020

Fishes Of The Dakotas, Kathryn Schlafke

Electronic Theses and Dissertations

Biological reference materials play a critical role in studies of species biodiversity, biology, distribution, and historic diversity. Since the publications Fishes of North Dakota (Hankinson, 1929) and Fishes of South Dakota (Bailey and Allum, 1962), no new books have attempted to update the knowledge gained from the past decades of fish surveys and incorporate georeferenced collections at the state level. The last published book with the most complete accounts of fishes from North Dakota and South Dakota is the Distribution of Fishes in North and South Dakota Basins affected by the Garrison Diversion Unit (Owen et al. 1981) which includes …


The Effect Of Neonicotinoid Clothianidin On Ring-Necked Pheasant Survival And Reproduction, Michael Sundall Jan 2020

The Effect Of Neonicotinoid Clothianidin On Ring-Necked Pheasant Survival And Reproduction, Michael Sundall

Electronic Theses and Dissertations

Ring-necked pheasants (Phasianus colchicus) are economically important to the state of South Dakota bringing in over one hundred million dollars in revenue each season. The population is known to fluctuate temporally for many reasons, often weather related. Unfortunately, no research has been conducted involving ring-necked pheasants that evaluated the impact or interaction of neonicotinoids on the species. The objective of our study was to gain an understanding of how the neonicotinoid, Clothianidin, affects survival and breeding in pheasants. Our first experiment was to determine if there was a selection bias for seeds treated with neonicotinoids. In this experiment, eight ring-necked …


Development Of Methods To Improve Lactose Recovery From Permeate And Drying Characteristics Of Greek Acid Whey, Venkateswarlu Sunkesula Jan 2020

Development Of Methods To Improve Lactose Recovery From Permeate And Drying Characteristics Of Greek Acid Whey, Venkateswarlu Sunkesula

Electronic Theses and Dissertations

Growth of higher protein dairy products and ingredients such as cheese, Greek yogurt, whey protein concentrates, and milk protein concentrates is limited by the amount of co-product generated and the ability to process them into value added ingredients. Finding value for all the co-products will help dairy industry to meet the growing demand for dairy protein products and ingredients. Commercial scale evaluation of new technologies for improving lactose crystallization and drying ability of Greek yogurt acid whey will help dairy industry to better utilize different dairy co-products. Commercially, lactose is manufactured from concentrated permeate by cooling and separating α-lactose monohydrate …


Characterization Of Bison Finishing And Harvest Systems: Effects On Carcass And Meat Quality Characteristics, Jessica Janssen Jan 2020

Characterization Of Bison Finishing And Harvest Systems: Effects On Carcass And Meat Quality Characteristics, Jessica Janssen

For objectives 1 and 2: Grain- (n=108) and grass- (n=93) finished bison heifers were slaughtered at 28 mo of age, at approximately 20 h postmortem, carcass measurements …


Allopurinol Alters The Expression Of Cytokines And Mediators Of Immune Cells In The Systemic 2 Tissue By Decreasing Plasma Urate., Lundrim S. Marku Jan 2020

Allopurinol Alters The Expression Of Cytokines And Mediators Of Immune Cells In The Systemic 2 Tissue By Decreasing Plasma Urate., Lundrim S. Marku

Graduate Theses, Dissertations, and Problem Reports (ETD)

Diminished levels of urate have been linked to oxidative stress in birds and mammals. Urate, a major antioxidant that lowers reactive oxygen/nitrogen species (ROS/RNS), is thought to ameliorate the effects. The relationship between reduced urate, the immune system and the pathogenesis of the intestine, the liver or the brain has not been well characterized in avians. Moreover, recent studies have proposed that an increased permeability in the intestine due to some insult can induce inflammation in peripheral organs such as the brain. Allopurinol, a relatively toxic purine analogue that serves as a xanthine oxidase inhibitor, reduces urate levels which can …


Effect Of Sire Breed On Grass-Based Lamb Production, Camren L. Maierle Jan 2020

Effect Of Sire Breed On Grass-Based Lamb Production, Camren L. Maierle

Graduate Theses, Dissertations, and Problem Reports (ETD)

Improvement of lamb performance in low-input operations may prove vital for the sustainability of eastern US sheep production. Maintaining growth while improving carcass conformation using terminal sire crossbreeding systems may increase value in a pasture-based system. Therefore, the aim of this study was to compare effects of terminal sire breed on parasitism, growth, marketability of grazing lambs. Suffolk (SU; n = 2) and Texel (TX; n = 2) sires were mated to commercial ewes at the WVU Organic Farm. April-born lambs were managed on pasture as one group until weaning (mid-June), then were separated into 3 replicates per sire breed. …


Impact Of Sire Selection And Breed On Parasite Resistance In Sheep, Andrew Ryan Weaver Jan 2020

Impact Of Sire Selection And Breed On Parasite Resistance In Sheep, Andrew Ryan Weaver

Graduate Theses, Dissertations, and Problem Reports (ETD)

Selection within and among breeds are strategies to mitigate the impact of parasitism given failing chemotherapeutics. While Texels have improved marketability compared to other parasite-resistant breeds, the mechanism by which Texels reduce fecal egg count (FEC) is unclear. The immune response to Haemonchus contortus (Hc) was compared in Texel, parasite-resistant St. Croix, and parasite-susceptible Suffolk sheep. Adult worms exposed to St. Croix- and Texel-derived peripheral blood mononuclear cells and serum in vitro had greater binding around the reproductive structures than Suffolk and worm egg release tended to be affected by breed (P = 0.09). Resistance in Texels …


Evaluating Inorganic Feed Phosphate Type And Further Potential Of Phytase Supplementation Using A Commercial Broiler Model, Angela Elsie Lamp Jan 2020

Evaluating Inorganic Feed Phosphate Type And Further Potential Of Phytase Supplementation Using A Commercial Broiler Model, Angela Elsie Lamp

Graduate Theses, Dissertations, and Problem Reports (ETD)

Optimizing feed formulation of poultry diets may be achieved by proper utilization of nutrients and feed additives. This will provide a less expensive and nutrient efficient diet to the bird. An experiment was conducted to evaluate early broiler performance, tibia mineralization, and mineral digestibility of broilers fed diets that differed in inorganic feed phosphates (IFP) but that were formulated to be either similar in dietary non-phytate phosphorus (nPP) and calcium to phosphorus ratio (Ca:P), total mineral content, or calculated prececal digestible phosphorus (CPDP). Dicalcium phosphate (DCP), monodicalcium phosphate (MDP), monocalcium phosphate (MCP), and defluorinated phosphate were used in formulations with …


Nest Success In A Grassland Bird Community: Microsite Selection & A Case For Nest Height Manipulation, Matt Kneitel Jan 2020

Nest Success In A Grassland Bird Community: Microsite Selection & A Case For Nest Height Manipulation, Matt Kneitel

Masters Theses

Grassland birds are a sensitive community and populations around the country have been declining. They are susceptible to low nest success due to loss of habitat and the small, fragmented patches that remain are often subjected to elevated levels of nest predation. The American goldfinch (Spinus tristis), which uses grasslands for feeding and nesting, is understudied given its abundance, due in part to its late-season nesting habits, and selection of taller woody vegetation as nesting substrate, which is atypical for many grassland nesting birds. American goldfinches were incorporated in this study which included nest height manipulation of goldfinch …


Seasonal Temperature Changes In Three Midwestern Wastewater Streams And The Effects On Fish Assemblages And Physiology, Ryan William Sparks Jan 2020

Seasonal Temperature Changes In Three Midwestern Wastewater Streams And The Effects On Fish Assemblages And Physiology, Ryan William Sparks

Masters Theses

Midwestern United States undergo extreme temperature and precipitation fluctuations throughout the year, which leads to changing habitats within Illinois river systems. Wastewater treatment facilities have long been used to treat sewage and reduce the organic products in sewage before releasing it into aquatic environments. Wastewater treatment facilities must maintain optimal conditions, especially temperature, for reproduction and growth of facilitated bacteria that break down organic materials in wastewater. The objectives for this study were to determine the thermal effects of wastewater treatment facilities on receiving waters; and secondly, to investigate the influence of these wastewater facilities on fish abundance and assemblages. …


Aging Techniques & Population Dynamics Of Blue Suckers (Cycleptus Elongatus) In The Lower Wabash River, Dakota S. Radford Jan 2020

Aging Techniques & Population Dynamics Of Blue Suckers (Cycleptus Elongatus) In The Lower Wabash River, Dakota S. Radford

Masters Theses

The Blue Sucker, Cycleptus elongatus, occurs in large rivers primarily in the Mississippi River basin. Their imperiled status has called attention to the need for its management and protection. Estimating age is crucial for directing management, but past studies have varied in their choice of hard structure, resulting in uncertainty regarding the basic life history of this species. Because the Wabash River Blue Sucker population may be one of few surveyable populations with high abundance and successful reproduction, their demographics can provide a benchmark against which threatened populations can be compared. We harvested Blue Suckers (n = 168) …


Ethical Considerations For Invertebrates, Scarlett R. Howard, Matthew R.E. Symonds Jan 2020

Ethical Considerations For Invertebrates, Scarlett R. Howard, Matthew R.E. Symonds

Animal Sentience

Mikhalevich & Powell (2020) have built on the discussion about which species deserve inclusion in animal ethics and welfare considerations. Here, we raise questions concerning the assessment criteria. We ask how to assess different species for their ability to fulfill the criteria, which criteria are most important, how we quantify them (absolute or on a continuum), and how non-animals such as fungi and plants fit into this paradigm.


Sentience In Evolutionary Context, Jon Mallatt, Todd E. Feinberg Jan 2020

Sentience In Evolutionary Context, Jon Mallatt, Todd E. Feinberg

Animal Sentience

We appreciate the goals of Mikhalevich & Powell (M&P) and largely agree with their conclusions but we differ on some of their definitions and terms. Affects (emotional feelings) should be part of sentience. Although the evidence presented for insect sentience is strong, we list some of the counterevidence that should be considered. Our own research supports M&P’s choice of arthropods, cephalopods, and vertebrates as the only sentient organisms with moral status.


Rethinking Rewilding Through Multispecies Justice, Danielle Celermajer Jan 2020

Rethinking Rewilding Through Multispecies Justice, Danielle Celermajer

Animal Sentience

Baker & Winkler’s argument that some humans, especially some Indigenous peoples, neither conceive of themselves as ontologically distinct from nature, nor do they organize their lives as such, is an important one. However, one needs to understand how colonialism and global capitalism have drawn Indigenous peoples and animals into new political economies. The new situation and the constrained opportunities available may have introduced a range of injustices or forms of violence that did not previously exist. This commentary proposes how a multispecies justice lens might assist in evaluating the most just arrangement for all parties, human and non-human.


The Wholeness Of Nature, Marthe Kiley-Worthington Jan 2020

The Wholeness Of Nature, Marthe Kiley-Worthington

Animal Sentience

The target article outlines various positions on conservation and preservation but ignores practical considerations of management since there is no wild habitat left. Population controls, either human or nonhuman mammals, are not discussed. The suggestions for legal changes are vague and will require much more thinking about how to integrate animal welfare with wildlife conservation concerns. “Freedoms” as outlined in the human bill of rights might help with decision making for improving animal welfare. Other commentators have made anthropocentric judgements concerning animal welfare, ignoring the importance of developing other ways of seeing and understanding the “multiplicity within unity,” combining empirical …


Bigheaded Carp Spatial Reproductive Dynamics And Population Genetics In Large River Tributaries, Samuel J. Schaick Jan 2020

Bigheaded Carp Spatial Reproductive Dynamics And Population Genetics In Large River Tributaries, Samuel J. Schaick

Masters Theses

Fisheries managers are devoting considerable effort, time, and funding towards limiting the spread of invasive Bighead and Silver (bigheaded) Carp. A better understanding of factors that influence spatial patterns of bigheaded carp reproduction can help fisheries managers prevent their spread. To examine factors that influence spatial patterns of reproduction, we sampled ichthyoplankton using drift nets and larval push nets in three tributaries of the Illinois and Wabash Rivers March-September 2016-2018. We compared relative abundances of bigheaded carp eggs and larvae among tributaries using catch per unit effort (CPUE). Abiotic data were analyzed from individual study tributaries and pooled among tributaries …


Canine And Criminal Bias: The Relationship Between Stereotypes And Perceptions Of Punishment, Jamie I. Thomas Jan 2020

Canine And Criminal Bias: The Relationship Between Stereotypes And Perceptions Of Punishment, Jamie I. Thomas

Graduate Research Theses & Dissertations

In this thesis I provide an analysis of punitive perceptions of animal crimes and argue that the lack of value seen in animal’s lives affects perceptions of punishment for animal crimes. Specifically, I examine the role of animal attitudes and race on perceptions of crimes against dogs and will address the following question with a vignette survey design: How do racial stereotypes interact with dog breed stereotypes when considering punishment for animal crime? This research expands on factors that influence perceptions of punishment of animal crime, including racial differences that may affect attitudes about animals. This study contributes to the …


Multivariate Analysis Of Open Field Exploration Identifies Latent Spatial And Social Behavioral Axes In Domestic Dogs, Budhaditya Chowdhury, Moira Van Staaden, Robert Huber Jan 2020

Multivariate Analysis Of Open Field Exploration Identifies Latent Spatial And Social Behavioral Axes In Domestic Dogs, Budhaditya Chowdhury, Moira Van Staaden, Robert Huber

Advanced Science Research Center

Recent methodological advances in studying large scale animal movements have let researchers gather rich datasets from behaving animals. Often collected in small sample sizes due to logistical constraints, these datasets are however, ideal for multivariate explorations into behavioral complexity. In behavioral studies of domestic dogs, although automated data loggers have recently seen increasing use, a comprehensive framework to identify complex behavioral axes is lacking. Dog behavioral studies frequently rely on subjective ratings, despite demonstrable evidence that these are insufficient for identifying behavioral variables. Taking advantage of dogs’ innate running abilities and readily available GPS data loggers, we extracted latitude-longitude coordinates …


Short-Term Estimate Of Finfish Bycatch Discards In The Inshore Artisanal Shrimp Fishery Of Guyana, Leanna Kalicharan, Hazel A. Oxenford Jan 2020

Short-Term Estimate Of Finfish Bycatch Discards In The Inshore Artisanal Shrimp Fishery Of Guyana, Leanna Kalicharan, Hazel A. Oxenford

Gulf and Caribbean Research

The artisanal shrimp fishery in Guyana is important for livelihood and food security, involving around 300 vessels owned and crewed exclusively by Guyanese nationals. This fishery uses Chinese seines and operates in major river estuaries. It targets penaeid shrimp, but also retains some finfish and is known to discard a significant but undocumented quantity of smaller finfish bycatch. The lack of knowledge regarding the bycatch is a concern for fishery management and biodiversity conservation. In this study, we quantify for the first time the finfish bycatch discards through onboard observations (July—August 2016) of a single typical vessel operating in the …


Habitat Characterization Of Juvenile Atlantic Tarpon (Megalops Atlanticus) In Isle Of Youth, Cuba, Zenaida M. Navarro-Martínez, Jorge Angulo-Valdés, Lisandra García-Córdova, Aaron Adams Jan 2020

Habitat Characterization Of Juvenile Atlantic Tarpon (Megalops Atlanticus) In Isle Of Youth, Cuba, Zenaida M. Navarro-Martínez, Jorge Angulo-Valdés, Lisandra García-Córdova, Aaron Adams

Gulf and Caribbean Research

Tarpon is considered a ‘Vulnerable’ species by IUCN but is also a highly prized recreational species. It is reportedly abundant in Cuba and may be threatened by high levels of fishing pressure. However, the current knowledge about Tarpon habitat characteristics and ecology in Cuba is very poor, which limit any attempt for its management and conservation. Here we summarize abiotic characteristics of juvenile Tarpon habitats in Lanier Swamp, Isle of Youth, Cuba, which is a RAMSAR site and Faunal Refuge. Three locations in Lanier Swamp were sampled for juvenile Tarpon presence during 2015-2017: Colony Lagoon (CL), Punta Francés Lagoon (PFL) …


First Records For Spawning Of Caribbean Acropora Species In Colombian Mpas, David M. Hudson, Barrett L. Christie, Luis A. Gómez-Lemos, Camilo Valcarcel, Diego Duque, Juan C. Zárate Arévalo, Jaime Rojas, Otto Reyes, Milena Marrugo, Maria Rosa, Israel A. Caicedo Torrado, Diana Tarazona, Carlos Zuluaga Jan 2020

First Records For Spawning Of Caribbean Acropora Species In Colombian Mpas, David M. Hudson, Barrett L. Christie, Luis A. Gómez-Lemos, Camilo Valcarcel, Diego Duque, Juan C. Zárate Arévalo, Jaime Rojas, Otto Reyes, Milena Marrugo, Maria Rosa, Israel A. Caicedo Torrado, Diana Tarazona, Carlos Zuluaga

Gulf and Caribbean Research

Estimates of Colombian Caribbean coral percent cover in the Southern Caribbean are consistent with those throughout the Caribbean Sea, which has declined to about 10% of historical levels in the last few decades. Human activities like destructive fishing techniques in the marine parks have degraded the reefs over the last few decades. Colombia’s Marine Protected Areas (MPAs) have thousands of square kilometers to map and patrol and few resources to devote to scientific and restoration efforts. Efforts to implement sexual reproduction techniques for restoration are starting to successfully propagate and settle corals on ceramic plates for reef deployment in the …


Prediction Of Warner-Bratzler Shear Force, Intramuscular Fat, Drip-Loss And Cook-Loss In Beef Via Raman Spectroscopy And Chemometrics, Raquel Cama-Moncunill, Jamie Cafferky, Caroline Augier, Torres Sweeney, Paul Allen, Alessandro Ferragina, Carl Sullivan, Andrew Cromie, Ruth Hamill Jan 2020

Prediction Of Warner-Bratzler Shear Force, Intramuscular Fat, Drip-Loss And Cook-Loss In Beef Via Raman Spectroscopy And Chemometrics, Raquel Cama-Moncunill, Jamie Cafferky, Caroline Augier, Torres Sweeney, Paul Allen, Alessandro Ferragina, Carl Sullivan, Andrew Cromie, Ruth Hamill

Articles

Rapid prediction of beef quality remains a challenge for meat processors. This study evaluated the potential of Raman spectroscopy followed by chemometrics for prediction of Warner-Bratzler shear force (WBSF), intramuscular fat (IMF), ultimate pH, drip-loss and cook-loss. PLS regression models were developed based on spectra recorded on frozen-thawed day 2 longissimus thoracis et lumborum muscle and validated using test sets randomly selected 3 times. With the exception of ultimate pH, models presented notable performance in calibration (R2 ranging from 0.5 to 0.9; low RMSEC) and, despite variability in the results, promising predictive ability: WBSF (RMSEP ranging from 4.6 to 9 …
