Investigating The Mechanisms Of Freeze Tolerance In Lemna Minor, Tamara Bouchard

Honors Theses and Capstones

Freezing presents a significant abiotic stress to aquatic plants, yet little is known about the mechanisms by which species like Lemna minor (duckweed) survive subzero temperatures in nature. This study investigates whether L. minor employs freeze-avoidance or freeze-tolerance strategies and explores the potential role of its microbiome in enhancing cold resilience. Using both field-collected fronds from naturally frozen ponds and controlled freezing experiments in the lab, I assessed survival through viability staining and post-thaw survival. Results showed that L. minor can survive natural ice encasement and that prior cold acclimation significantly improves tissue survival under induced freezing. Trypan blue staining …

Economic Analysis And Profitability Of Honey Production And Marketing In Cross River State, Nigeria, Joseph A. Ugbe, Tee T.N., Ancha P.U

Journal of Bioresource Management

The significance of honey in the socio-economic livelihoods of rural and semi-urban populations is paramount, as it tackles issues such as unemployment, income, and ecosystem preservation. The decrease in the timber industry has caused numerous individuals who rely on forests for their income to be without jobs, making it difficult to find other ways to make a living. This study examines the economic analysis and profitability of honey production and marketing in Cross River State, Nigeria, over 5 years (2017-2021) for sustainable forest management. Six hundred and eighty-four (684) respondents were selected from three ecological zones in the state using …

Data For "Linking Previous Experiences To Behavior And Health In The Honey Bee (Apis Mellifera)"", Rebecca R. Westwick, Clare C. Rittschof, Gavin P. Brackett, Cameron E. Brown, Bethany J. Ison, Zainulabbeudin Syed, Anna M. Foose

Entomology Research Data

An organism’s ability to respond to changing conditions can be vital to its success. Indeed, plasticity is a common feature of living organisms. Much of the research in this area, though, has focused on effects caused by environmental conditions. What has received relatively less attention is how social experiences and broader features of an organism’s social environment can lead to long-lasting changes in health and behavior. This knowledge gap exists despite the well-documented existence of health and behavioral effects after social interactions in certain taxa such as humans.

Social insects such as honey bees provide an excellent opportunity to better …

An Automatic System To Evaluate Bait Station Visitation By Brown Treesnakes And Mongooses, Robert T. Sugihara, William C. Pitt, Are R. Berentsen, Francis L. Benevides Jr.

Human–Wildlife Interactions

Understanding the temporal, spatial, and behavioral patterns of the free-ranging target species in response to candidate baits and baiting strategies is important to ensure control success. This information can also assist in the development and deployment of feeding stations and can exclude non-target species while constituting effective bait delivery and control strategies for certain invasive animals, especially at environmentally sensitive sites. We used passive integrated transponder (PIT) tags in conjunction with very-high frequency radio-telemetry to remotely record bait station visitations and evaluate bait attractiveness in separate field research studies of brown treesnakes (Boiga irregularis) on Andersen Air Force …

Establishment Of Pollinator Habitat Within A Livestock Pasture Ecosystem, Roshani Sharma Acharya

Graduate Theses and Dissertations

Pollinators are important for fertilization, setting fruits, and seed development of more than 78% of the flowering plants that provide food for human beings and other species. Use of pollinators to maximize crop production is a proven agricultural practice; however, it has been less explored in livestock forage production systems. This study investigated pollinator abundance and diversity in pastures using different sampling methods and determined the impact of different pasture management practices on insect pollinators in a livestock pasture ecosystem. In Chapter 2, utility of four different colors of pan trap (blue, green, yellow, and purple) for sampling bees in …

Phylogeny And Population Genetic Analyses Reveals Cryptic Speciation In The Bombus Fervidus Species Complex (Hymenoptera: Apidae), Jonathan B. Koch, Juanita Rodriguez, James P. Pitts, James P. Strange

Ecology Center Publications

Bumble bees (Bombus Latrielle) are significant pollinators of flowering plants due to their large body size, abundant setae, and generalist foraging strategies. However, shared setal coloration patterns among closely and distantly related bumble bee species makes identification notoriously difficult. The advent of molecular genetic techniques has increased our understanding of bumble bee evolution and taxonomy, and enables effective conservation policy and management. Individuals belonging to the North American Bombus fervidus species-complex (SC) are homogenous in body structure but exhibit significant body color phenotype variation across their geographic distribution. Given the uncertainty of the genealogical boundaries within the SC, some …

Wild Bees Of Grand Staircase-Escalante National Monument: Richness, Abundance, And Spatio-Temporal Beta-Diversity, Olivia Messinger Carril, Terry Griswold, James Haefner, Joseph S. Wilson

All PIRU Publications

Interest in bees has grown dramatically in recent years in light of several studies that have reported widespread declines in bees and other pollinators. Investigating declines in wild bees can be difficult, however, due to the lack of faunal surveys that provide baseline data of bee richness and diversity. Protected lands such as national monuments and national parks can provide unique opportunities to learn about and monitor bee populations dynamics in a natural setting because the opportunity for large-scale changes to the landscape are reduced compared to unprotected lands. Here we report on a 4-year study of bees in Grand …

Radical Social Ecology As Deep Pragmatism: A Call To The Abolition Of Systemic Dissonance And The Minimization Of Entropic Chaos, Arielle Brender

Student Theses 2015-Present

This paper aims to shed light on the dissonance caused by the superimposition of Dominant Human Systems on Natural Systems. I highlight the synthetic nature of Dominant Human Systems as egoic and linguistic phenomenon manufactured by a mere portion of the human population, which renders them inherently oppressive unto peoples and landscapes whose wisdom were barred from the design process. In pursuing a radical pragmatic approach to mending the simultaneous oppression and destruction of the human being and the earth, I highlight the necessity of minimizing entropic chaos caused by excess energy expenditure, an essential feature of systems that aim …

Why We Still Need To Worry About Bees, Meaghan Lee Callaghan

Capstones

American honey bees, and other native bee species, are still in decline, though the specter of colony collapse disorder may be fading behind us. Colony decline, the loss of bees overwinter experienced across the country at a quarter to third lost per hive (sometimes more), is now expected. Losses can include those from colony collapse disorder. The author discusses the different causes for colony decline and speaks to bee health scientists and local beekeepers.

Effect On Bees Of Insecticides Used On Rape, A C. Kessell

Journal of the Department of Agriculture, Western Australia, Series 4

Rapeseed could provide beekeepers in Western Australia with a valuable new honey crop—hut insecticidal spraying of rape at flowering time is a potentially serious threat to most commercial beekeepers.

There are indications that insect pollination may improve rapeseed yields, so both growers and beekeepers could gain from a co-operative approach to the problem. Spraying after sundown and preventing spray drift to nearby apiaries should avoid most losses.

Bee Farming : Honey Flora Of Western Australia, R S. Coleman

Journal of the Department of Agriculture, Western Australia, Series 4

A GOOD knowledge of the nectar producing plants of the State is essential for success in commercial beekeeping.

The beekeeper who has a good knowledge of which plants produce good flows, when the flows might be expected, and where good stands of those plants may be found is the one who has the best chance of success.

Bee Farming : Maintaining Productive Stock, R S. Coleman

Journal of the Department of Agriculture, Western Australia, Series 4

EVERY bee hive must be a productive unit, headed by a young vigorous queen, to to make sure of the greatest possible return from capital invested in the commercial apiary.
