Size And Density Of Upside-Down Jellyfish, Cassiopea Sp., And Their Impact On Benthic Fluxes In A Caribbean Lagoon, Chester B. Zarnoch, Noshin Hossain, Erika Fusco, Mary Alldred, Timothy J. Hoellein, Sophia Perdikaris Jan 2020

Size And Density Of Upside-Down Jellyfish, Cassiopea Sp., And Their Impact On Benthic Fluxes In A Caribbean Lagoon, Chester B. Zarnoch, Noshin Hossain, Erika Fusco, Mary Alldred, Timothy J. Hoellein, Sophia Perdikaris

School of Global Integrative Studies: Faculty Publications

Anthropogenic disturbances may be increasing jellyfish populations globally. Epibenthic jellyfish are ideal organisms for studying this phenomenon due to their sessile lifestyle, broad geographic distribution, and prevalence in near-shore coastal environments. There are few studies, however, that have documented epibenthic jellyfish abundance and measured their impact on ecological processes in tropical ecosystems. In this study, the density and size of the upside-down jellyfish (Cassiopea spp.) were measured in Codrington Lagoon, Barbuda. A sediment core incubation study, with and without Cassiopea, also was performed to determine their impact on benthic oxygen and nutrient fluxes. Densities of Cassiopea were 24–168 …

Novel Mechanism For Turning Performance In Bluefin Tuna, Abigail Downs Jan 2020

Novel Mechanism For Turning Performance In Bluefin Tuna, Abigail Downs

West Chester University Master’s Theses

Scombrid fishes can attain exceptional swimming speeds due to their thunniform, lift-based propulsion, large muscle mass, and fusiform body shape. A rigid body restricts maneuverability for aquatic organisms. To test if turning maneuvers by the rigid-bodied Pacific bluefin tuna (Thunnus orientalis) are constrained, captive animals were video recorded from above as the animals routinely swam around a large circular tank or during feeding bouts. The turning performance was classified into three different types of turns: 1) glide turn, where the tuna uses the caudal fin as a rudder to passively move through the turn, 2) powered turn, where …


Intraspecific Aggression Towards Common Bottlenose Dolphin Calves, Northern Gulf Of Mexico, Errol Ronje, Sarah Piwetz, Heidi Whitehead, Keith D. Mullin Jan 2020

Intraspecific Aggression Towards Common Bottlenose Dolphin Calves, Northern Gulf Of Mexico, Errol Ronje, Sarah Piwetz, Heidi Whitehead, Keith D. Mullin

Gulf and Caribbean Research

Infanticide has been widely documented throughout the animal kingdom, and has generally been viewed as an evolved, or adaptive behavior for the perpetrators. Infanticide motivated by increased sexual access to females with calves, or the elimination of potential genetic competition in the form of calf-directed aggression or infanticide, has been proposed for delphinids including killer whales, Indo-Pacific humpback dolphins, Guiana dolphins, and bottlenose dolphins. However, reports of intraspecific aggression towards bottlenose dolphin calves are relatively infrequent, and accounts of confirmed infanticide are rarer still. Reporting instances of intraspecific calf-directed aggression aids researchers to better understand the socio-behavioral context of these …


Asian Elephant Rescue, Rehabilitation And Rewilding, Liv Baker, Rebecca Winkler Jan 2020

Asian Elephant Rescue, Rehabilitation And Rewilding, Liv Baker, Rebecca Winkler

Animal Sentience

Thailand has fewer than 10,000 elephants left. More of them are living in captivity to serve the tourist industry under grim conditions than are living free in what is left of their wild habitat. Conservation efforts need to be focused on all surviving members of the species, captive and free, but they need to take into account the inextricable entanglement of human and nonhuman animal lives in Thailand today. There is an opportunity for rescuing, rehabilitating and reintroducing captive elephants to the wild with the help of the traditional expertise of a mahout culture that has been elephant-keeping for centuries. …


Rewilding And Domestication: Clarifying Terminology, Catia Correia-Caeiro Jan 2020

Rewilding And Domestication: Clarifying Terminology, Catia Correia-Caeiro

Animal Sentience

Baker & Winkler (B&W) describe the state of Asian elephant conservation, raising unique issues, and proposing a direction based on rewilding. The long history and socio-biology of elephants and humans has some parallels with the domestication of dogs (and other species). However, markers of domestication seem absent from elephants. The proper use of terms such as “wild” and “domestic” is crucial in defining the best conservation strategies, and, more important, in attending to the welfare needs of individuals, which can differ between wild and domestic animals. B&W’s target article represents an important starting point for discussion around elephant conservation, but …


Innovation In Meat Production: A Problem And An Opportunity, Christopher J. Bryant Jan 2020

Innovation In Meat Production: A Problem And An Opportunity, Christopher J. Bryant

Animal Sentience

Innovation in meat production has enabled modern humans to inflict far greater harm on animals, the environment, and public health than was possible just a few decades ago. Wiebers & Feigin aptly express the urgency with which these issues must be addressed. Those advocating for animals on moral grounds face resistance from omnivores citing taste, price and convenience. Further innovation in meat production (plant-based and cultured meat) will enable us to preserve the experience of eating meat whilst phasing out the many problems caused by industrial animal farming.


Covid-19, Evolution, Brains And Psychology, Frederick Toates Jan 2020

Covid-19, Evolution, Brains And Psychology, Frederick Toates

Animal Sentience

Attention needs to be directed to the processes that control behavior in humans and the adaptive problems that they solved in our early evolutionary environment. The evolutionary mismatch between the current environment and the human brain can yield important insights into the problems that beset us in the context of environmental degradation and nonhuman animal welfare.


Re-Engage With The World For Global Health And Animal Welfare, Bradley J. Bergstrom Jan 2020

Re-Engage With The World For Global Health And Animal Welfare, Bradley J. Bergstrom

Animal Sentience

Wiebers & Feigin (2020) make a strong argument for measures that would limit future zoonoses, such as the COVID-19 pandemic, by closing live-animal markets, changing our habits of food consumption and production, and reducing habitat destruction. These would help human health, animal welfare, and conservation of at-risk wildlife all at the same time. China’s command-and-control government can accomplish some of these things by edict, but slower-to-act western democracies play a surprisingly large role in these global problems by the power of their consumerism, including the illicit wildlife trade. We citizens need to insist that our government use all of its …


Thinking Longer, Looking Deeper, Ronnie Z. Hawkins Jan 2020

Thinking Longer, Looking Deeper, Ronnie Z. Hawkins

Animal Sentience

We need to situate the present crisis within the larger context of what we humans have done to the nonhuman forms of life with which we evolved, taking a longer view of our own evolutionary origins and a deeper look at what might be a more appropriate role for our species to play within the Biosphere.


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 …


Cognition, Movement And Morality, Thomas R. Zentall Jan 2020

Cognition, Movement And Morality, Thomas R. Zentall

Animal Sentience

Each of the criteria for determining which should be given moral standing has its shortcomings. The criterion of cognitive is especially weak. That research on comparative cognition may default to the simplest account is not grounds for abandoning this scientific practice. Instead, we should dissociate scientific evidence of cognitive ability from moral obligation. In addition to the criteria suggested by Mikhalevich & Powell for including species in welfare protections, I would suggest a very old one — the ability to physically move.


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.


Insect Sentience And The Rise Of A New Inclusive Ethics, David Baracchi, Luigi Baciadonna Jan 2020

Insect Sentience And The Rise Of A New Inclusive Ethics, David Baracchi, Luigi Baciadonna

Animal Sentience

Welfare protections for vertebrates are grounded in the belief that vertebrates are sentient and capable of feeling whereas invertebrates are not. We agree with Mikhalevich & Powell that the exclusion of small-brained invertebrates from bioethics is not warranted by the current state of the scientific evidence. The choice to promote protection for certain invertebrates should be based on the Animal Sentience Precautionary Principle (ASPP). This principle should not prevent us from conducting experimental research with non-human animals to advance knowledge. However, we believe that it is important to outline practical guidelines to manage the wellbeing of invertebrates, while accumulating further …

The Biofiltration Ability Of Asparagus Densiflorus To Remove Sulfur Dioxide From The Indoor Atmosphere, Rhiannon De La Rosa, Mary Savin Jan 2020

The Biofiltration Ability Of Asparagus Densiflorus To Remove Sulfur Dioxide From The Indoor Atmosphere, Rhiannon De La Rosa, Mary Savin

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Sulfur dioxide is an inorganic compound (IC) and air pollutant that causes health risks in humans. The buildup of sulfur dioxide (SO2) in enclosed indoor spaces is, therefore, a concern to human health, especially since the average person spends 90% of his/her time indoors. This study focused on decreasing SO2 concentration in a cost-effective and simple way—by using botanical biofiltration, or the uptake of pollutants by plants. Research in biofiltration has focused mostly on the remediation of volatile organic compounds (VOC). However, research has also shown that plant species that remediate VOC efficiently also have the potential for efficient IC …

Decomposition In Pasture Soil Receiving Excreta From Ruminants Fed Alfalfa Forage Diet Supplemented With Increasing Proportions Of Sericea Lespedeza Legume, Yang Kai Tang, Mary C. Savin, Dirk Philipp, Ken Coffey, Jiangchao Zhao

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Healthy soil is fundamental to a productive pasture system as it will decompose labile organic matter and promote retention of carbon to build a stable, resistant pool of organic matter. An easy, standardized approach to measure decomposition and litter stabilization that is gaining popularity in both citizen science and research studies is the use of the Tea Bag Index. The Tea Bag Index is a relatively new method evaluating the loss of organic material in two different kinds of commercial tea bags (green tea and Rooibos tea) after burial in the soil for 90 days. The objective of this experiment …

Diet Of A Recently Reintroduced River Otter (Lontra Canadensis) Population In Taos County, New Mexico, Gabriela Alexandra Wolf-Gonzalez Jan 2020

Diet Of A Recently Reintroduced River Otter (Lontra Canadensis) Population In Taos County, New Mexico, Gabriela Alexandra Wolf-Gonzalez

Theses and Dissertations--Forestry and Natural Resources

North American river otters (Lontra canadensis), native to every U.S. state and Canada, experienced extensive population decreases and range reduction until the mid-20th century as a result of overexploitation and habitat loss during European colonization. The last known river otter in New Mexico was killed on the Gila River in 1953, although unverified reports continued thru 2008. After a nearly 60-year absence from New Mexico, 33 adult river otters were reintroduced to the Rio Pueblo de Taos in the northern part of the state between 2008-2010; however, they were not subsequently monitored or studied. I characterized diet of …

Sampling The Local Fare: Fishes At The Sam Israel House Pit (45gr76), Soap Lake, Washington, Adam Fruge Jan 2020

Sampling The Local Fare: Fishes At The Sam Israel House Pit (45gr76), Soap Lake, Washington, Adam Fruge

All Master's Theses

The Sam Israel site is a precontact archaeological complex with numerous fish bones at the north end of Soap Lake, Washington. Excavated in 1976, the fish remains recovered from there were never fully analyzed prior to this research. Since this inland Columbia Plateau site had thousands of fish bones, it contained untapped potential for our understanding of ancient local fish procurement. As such, I conducted a detailed analysis of 2,862 fish bone specimens from the Sam Israel House Pit locus to: study a larger sample of fish bones in greater detail than was done before; compare the distribution of fishes …


Group Differences In Mother-Infant Macaca Fascicularis Behavior, Parasite Load, And Body Condition Within An Anthropogenically Altered Forest, Elizabeth M.C. Coggeshall Jan 2020

Group Differences In Mother-Infant Macaca Fascicularis Behavior, Parasite Load, And Body Condition Within An Anthropogenically Altered Forest, Elizabeth M.C. Coggeshall

All Master's Theses

This study aimed to establish preliminary health and behavioral data, as well as understand group variation for a large population of Macaca fascicularis individuals within an anthropogenically altered monkey forest. A parasitic analysis of 40 mother and infant individuals showed that M. fascicularis carried 13 different parasitic taxa, and that there was parasitic variation between groups. Body condition scores were determined using a newly created and adapted body condition scale from 146 sampled mother macaques. Body condition scores were significantly different between groups, specifically the pond group when compared to the three other groups. Mother-infant behavioral differences were seen between …


Mommy Issues: Do Differential Rearing Histories Affect The Social Behavior Of Captive Chacma Baboons (Papio Ursinus), Madeleine Spencer Jan 2020

Mommy Issues: Do Differential Rearing Histories Affect The Social Behavior Of Captive Chacma Baboons (Papio Ursinus), Madeleine Spencer

All Master's Theses

I observed the behavior of 17 chacma baboons (Papio ursinus) in order to understand the relationship between rearing history, dominance hierarchy, and social behavior. The Centre for Animal Rehabilitation and Education (C.A.R.E.) has utilized hand-rearing in the past and is currently using a surrogate-rearing method. Hand-rearing involves one or more primary caregivers attending to an infant for 6 – 12 months. Surrogate-rearing involves one individual being the primary surrogate for the first 3 months of the infant’s life prior to bonding her or him to an adult female baboon before integrating both back into the surrogate’s troop. Mother-reared …


Hand Preference For Holding, Tapping, Probing And Digit-Feeding In Captive Adult Aye-Ayes (Daubentonia Madagascariensis), Robert Shaun Mayo Jan 2020

Hand Preference For Holding, Tapping, Probing And Digit-Feeding In Captive Adult Aye-Ayes (Daubentonia Madagascariensis), Robert Shaun Mayo

All Master's Theses

Aye-ayes are a species of lemur with several unique characteristics. They have the largest brain to body size ratio of any lemur and are the largest nocturnal primate. Insect larvae are a dietary staple. They use their elongated third digit to tap on structures such as tree bark and their large ears to listen for auditory changes caused by the larvae burrowing through the wood, which creates cavities in the wood. They use their rodent-like incisors to chew a hole in the wood and insert their third digit to probe the cavities, feeling for the larvae. After locating their prey, …


Spatiotemporal Partitioning Of Mammalian Mesopredators In Response To Drought And Urbanization In California's Central Valley, Chad W. Moura Jan 2020

Spatiotemporal Partitioning Of Mammalian Mesopredators In Response To Drought And Urbanization In California's Central Valley, Chad W. Moura

Cal Poly Humboldt theses and projects

Mammalian mesopredators commonly associated with human dominated landscapes often exhibit generalist diets, behavioral plasticity, and relatively high reproductive rates. Because of this wide range of adaptive traits, ecologists have been speculative of what conditions may drive species to change their activity and behavior to avoid or mitigate against resource competition, intraguild predation, and human disturbance. I investigated a community of common mesopredators within the Sacramento Metropolitan Area of California’s Central Valley to address whether species are spatially and/or temporally partitioning due to a defacto apex predator, coyotes (Canis latrans), and humans alongside large landscape altering disturbances: urbanization and drought. I …


Energy Development And Production In The Great Plains: Implications And Mitigation Opportunities, Jacqueline P. Ott, Bruce B. Hanberry, Mona Khalil, Mark W. Paschke, Max Post Van Der Burg, A.J. Prenni Jan 2020

Energy Development And Production In The Great Plains: Implications And Mitigation Opportunities, Jacqueline P. Ott, Bruce B. Hanberry, Mona Khalil, Mark W. Paschke, Max Post Van Der Burg, A.J. Prenni

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Energy is an integral part of society. The major US energy sources of fossil fuels (coal, oil, natural gas); biofuels (ethanol); and wind are concentrated in grassland ecosystems of the Great Plains. As energy de- mand continues to increase, mounting pressures will be placed on North American grassland systems. In this review, we present the ecological effects of energy development and production on grassland sys- tems. We then identify opportunities to mitigate these effects during the planning, construction, and pro- duction phases by using informed methodology and improved technology. Primary effects during energy development include small- and large-scale soil disturbance …


Workflow For Constructing Social Networks From Automated Telemetry Systems, Daizaburo Shizuka, Sahas Barve, Allison Johnson, Eric L. Walters Jan 2020

Workflow For Constructing Social Networks From Automated Telemetry Systems, Daizaburo Shizuka, Sahas Barve, Allison Johnson, Eric L. Walters

Biological Sciences Faculty Publications

1. Advances in datalogging technologies have provided a way to monitor the movement of individual animals at unprecedented spatial and temporal scales, both large and small. When used in conjunction with social network analyses, these data can provide insight into fine scale associative behaviors. The variety of technologies demand continuous progress in workflows to translate data streams from automated systems to social networks, based on biologically relevant metrics.

2. Here we present a workflow for generating flexible association matrices from automated radio-telemetry data that can be parsed into both spatial and temporal dimensions. These can then be used to generate …
