Eating Crickets? Nutrient Mineral Content Of Two Cricket Species And Chapul Cricket Protein Bars Using Mp-Aes, Nathan Hopkins 2018 Lynchburg College

Eating Crickets? Nutrient Mineral Content Of Two Cricket Species And Chapul Cricket Protein Bars Using Mp-Aes, Nathan Hopkins

Student Scholar Showcase

Global agriculture is beset by numerous challenges which must be surmounted to feed a developing world, from combating climate change to the cultivation of sustainable food products. This, in addition to protein and nutrient deficiencies in the developing world, makes considering alternative protein sources, such as a crickets, an attractive option. Crickets use a fraction of the land and water that protein sources like beef cattle do, and can be cultivated in urban environments in stacked boxes. This research investigation aims to quantify the nutrient mineral content (Iron, Sodium, Potassium, Calcium, and Magnesium) of two cricket species (Acheta domesticus & Gryllodes ...


Uvb Avoidance In Dendrobates Azereus Tadpoles, Matthew Sturtevant, Lee Kats, Agustin Vargas, Arthur Garnica 2018 Pepperdine University

Uvb Avoidance In Dendrobates Azereus Tadpoles, Matthew Sturtevant, Lee Kats, Agustin Vargas, Arthur Garnica

Seaver College Research And Scholarly Achievement Symposium

Most frogs are nocturnal, but dart frogs (Dendrobatidae) are diurnal and lack scales or hair that would protect them from UVB rays. Previous studies have demonstrated that adult dart frogs avoid UVB light. The purpose of this experiment was to test whether dart frog larvae would avoid UVB light when compared to local nocturnal treefrog larvae. For the experiment we used tadpoles of Dendrobates azureus and Pseudacris regilla. The tadpoles were put in tubs with a submerged shelter and exposed to 3 lighting conditions: UVB, no light and visible light. The tadpoles were exposed to only one lighting condition each ...


Bats Of Sint Eustatius, Caribbean Netherlands, Scott C. Pedersen, Peter A. Larsen, Sil A. Westra, Ellen van Norren, Wesley Overman, Gary G. Kwiecinski, Hugh H. Genoways 2018 South Dakota State University

Bats Of Sint Eustatius, Caribbean Netherlands, Scott C. Pedersen, Peter A. Larsen, Sil A. Westra, Ellen Van Norren, Wesley Overman, Gary G. Kwiecinski, Hugh H. Genoways

Mammalogy Papers: University of Nebraska State Museum

The bat fauna of the Caribbean island of Sint Eustatius consists of five documented species—Monophyllus plethodon, Brachyphylla cavernarum, Artibeus jamaicensis, Ardops nichollsi, and Molossus molossus—and one provisional species—Tadarida brasiliensis. The Insular Single-leaf Bat, M. plethodon, is reported in the scientific literature for the first time from Sint Eustatius based on material presented herein. The bat fauna of the island is considered to be unbalanced because only three species, which are the environmental generalists, are abundant, whereas the more specialized species are rare or absent from the fauna. It is our hypothesis that the unbalanced bat fauna on ...

An Analysis Of The Characteristics And Practices Of Selected Florida Small Livestock Producers: A Focus On Production And Processing, Jannette R. Bartlett, David Nii O. Tackie, Dana Reid, Akua Adu-Gyamfi, Angela Mckenzie-Jakes

Professional Agricultural Workers Journal

The study assessed the characteristics and practices of small livestock producers, emphasizing production and processing. Data were obtained from a convenience sample of seventy small producers from selected counties in Florida, and analyzed using descriptive statistics, including chi-square tests. The socioeconomic characteristics showed that part-time producers, White producers, middle-aged producers, fairly educated producers, and moderate-income producers dominated the group. A majority of the producers practiced rotational grazing, fed a combination of forage and concentrate, and less than half conducted soil tests regularly. Moreover, over half had parasite problems and treated them primarily with anthelmintics. Nearly all producers sold animals live ...


Investigating The Genetic Structure Of Northern Long-Eared Bats In Nebraska, Jonathan Korbitz 2018 University of Nebraska at Omaha

Investigating The Genetic Structure Of Northern Long-Eared Bats In Nebraska, Jonathan Korbitz

Student Research and Creative Activity Fair

Abstract:

The northern long-eared bat (Myotis septentrionalis) is one of many species of hibernating bats in North America affected by a recently discovered fungal disease called white-nose syndrome (WNS). Northern long-eared bats seem to be extremely susceptible to the disease with mass fatalities occurring among populations in eastern North America. Researchers in the eastern distribution of this species have performed mtDNA analysis to identify the population structure of the species; however, genetic analysis has yet to be done in western parts of its distribution. The goal of this study is to create a better understanding of the genetic makeup of ...


Hunting A Home: The Abandonment And Neglect Of Hunting Dogs, Jamie B. Walker 2018 Germanna Community College

Hunting A Home: The Abandonment And Neglect Of Hunting Dogs, Jamie B. Walker

Exigence

Each year, an immeasurable number of hunting dogs are found in emaciated, malnourished or even abusive conditions due to neglect and abandonment by their owners. These dogs, primarily hounds, have increasingly become a burden on animal shelters and have cast a negative light on hunting with dogs, particularly in Virginia. The difficulty in identifying the owners of these dogs has stymied law enforcement and animal welfare authorities for years. Mandatory microchipping, now compulsory in England, may be the key to protecting talented working dogs from neglect, cruelty and abandonment by uncaring owners. These microchips can allow abandoned animals to lead ...


Dog Behavior Co-Varies With Height, Bodyweight And Skull Shape, Paul D. McGreevy, Dana Georgevsky, Johanna Carrasco, Michael Valenzuela, Deborah L. Duffy, James A. Serpell 2018 University of Sydney

Dog Behavior Co-Varies With Height, Bodyweight And Skull Shape, Paul D. Mcgreevy, Dana Georgevsky, Johanna Carrasco, Michael Valenzuela, Deborah L. Duffy, James A. Serpell

Paul McGreevy, Ph.D.

Dogs offer unique opportunities to study correlations between morphology and behavior because skull shapes and body shape are so diverse among breeds. Several studies have shown relationships between canine cephalic index (CI: the ratio of skull width to skull length) and neural architecture. Data on the CI of adult, show-quality dogs (six males and six females) were sourced in Australia along with existing data on the breeds’ height, bodyweight and related to data on 36 behavioral traits of companion dogs (n = 8,301) of various common breeds (n = 49) collected internationally using the Canine Behavioral Assessment and Research Questionnaire (C-BARQ ...


Mute Swans, David R. Marks 2018 USDA-APHIS Wildlife Services

Mute Swans, David R. Marks

Wildlife Damage Management Technical Series

Mute swans (Cygnus olor) are an invasive species originally brought to the United States in the late 19th and early 20th centuries for ornamental ponds and lakes, zoos and aviculture collections. Original populations were located in northeastern states along the Hudson Valley but have since expanded to several Midwestern states and portions of the western U.S. and Canada. Mute swan damage includes competing with native waterfowl, destroying native plants, spreading disease, and colliding with aircraft. They are also considered a nuisance in some areas due to their abundant fecal droppings and aggressiveness towards people.

Mute swans can impact ecosystems ...


Individual Personality Differences In Goats Predict Their Performance In Visual Learning And Non-Associative Cognitive Tasks, Christian Nawroth, Pamela M. Prentice, Alan G. McElligott 2018 Queen Mary University of London

Individual Personality Differences In Goats Predict Their Performance In Visual Learning And Non-Associative Cognitive Tasks, Christian Nawroth, Pamela M. Prentice, Alan G. Mcelligott

Christian Nawroth, Ph.D.

Variation in common personality traits, such as boldness or exploration, is often associated with risk–reward trade–offs and behavioural flexibility. To date, only a few studies have examined the effects of consistent behavioural traits on both learning and cognition. We investigated whether certain personality traits (‘exploration’ and ‘sociability’) of individuals were related to cognitive performance, learning flexibility and learning style in a social ungulate species, the goat (Capra hircus). We also investigated whether a preference for feature cues rather than impaired learning abilities can explain performance variation in a visual discrimination task. We found that personality scores were consistent ...

A Note On Pigs’ Knowledge Of Hidden Objects, Christian Nawroth, Mirjam Ebersbach, Eberhard Von Borell

Christian Nawroth, Ph.D.

Object permanence is the notion that objects continue to exist even when they are out of observer’s sight. This ability is adaptive for free ranging animals who have to cope with a dangerous and highly changeable environment and allows them to be aware of predators sneaking in their proximity or to keep track of conspecifics or food sources, even when out of sight. Farm animals might also benefit from object permanence because the ability to follow the trajectory of hidden food or objects may lead to a higher predictability of subjects’ environment, which in turn might affect the level ...

Muskrats, James E. Miller 2018 Mississippi State University

Muskrats, James E. Miller

Wildlife Damage Management Technical Series

The muskrat (Ondatra zibethicus) is a common, semi-aquatic rodent native to the United States (Figure 1). It spends its life in aquatic habitats and is well adapted for swimming.

Although muskrats are an important part of native ecosystems, their burrowing and foraging activities can damage agricultural crops, native marshes and water control systems, such as aquaculture and farm ponds and levees. Such damage can significantly impact agricultural crops like rice that rely on consistent water levels for growth.

Muskrats also cause damage by eating agricultural crops, other vegetation, and crayfish, mussels and other aquaculture products. Loss of vegetation from muskrat ...


Wild Turkeys, James E. Miller 2018 Mississippi State University

Wild Turkeys, James E. Miller

Wildlife Damage Management Technical Series

Like other bird and mammal species whose populations have been restored through conservation efforts, wild turkeys (Figure 1) are treasured by many recreationists and outdoor enthusiasts. Wild turkeys have responded positively to wildlife habitat and population management. In some areas, however, their increased populations have led to increased damage to property and agricultural crops, and threats to human health and safety. Turkeys frequent agricultural fields, pastures, vineyards and orchards, as well as some urban and suburban neighborhoods. Because of this, they may cause damage or mistakenly be blamed for damage. Research has found that despite increases in turkey numbers and ...


An Historical Overview And Update Of Wolf-Moose Interactions In Northeastern Minnesota, L. David Mech, John Fieberg, Shannon M. Barber-Meyer 2018 USGS Northern Prairie Wildlife Research Centre

An Historical Overview And Update Of Wolf-Moose Interactions In Northeastern Minnesota, L. David Mech, John Fieberg, Shannon M. Barber-Meyer

USGS Northern Prairie Wildlife Research Center

Wolf (Canis lupus) and moose (Alces americanus) populations in northeastern Minnesota, USA, have fluctuated for decades and, based on helicopter counts, moose numbers declined to a new low from 2006 to about 2012. Other steep declines were found in 1991 and 1998 during periods when moose counts were done with fixed-wing aircraft; these declines also appeared to be real. Winter wolf numbers, monitored in part of the moose range, had been increasing since about 2002 to the highest population in decades in 2009. However, from 2009 to 2016, wolves decreased precipitously, and the moose- population decline leveled off from 2012 ...
