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 Nov 2018

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 authors ...

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 ...


South American Leaf-Cutter Bees (Genus Megachile) Of The Subgenera Rhyssomegachile And Zonomegachile, With Two New Subgenera (Hymenoptera: Megachilidae), Víctor H. González, Terry Griswold, Michael S. Engel Nov 2018

South American Leaf-Cutter Bees (Genus Megachile) Of The Subgenera Rhyssomegachile And Zonomegachile, With Two New Subgenera (Hymenoptera: Megachilidae), Víctor H. González, Terry Griswold, Michael S. Engel

All PIRU Publications

Leaf-cutter bees (genus Megachile Latreille) are among the most common and diverse group of bees. However, the identity and taxonomic placement of many species are problematic and species identification is often difficult. Some species are known only from a single specimen or from one of the sexes, and identification keys are not available for many groups. We address these taxonomic issues for the subgenera Rhyssomegachile Mitchell and Zonomegachile Mitchell, two poorly known South American lineages of leaf-cutter bees. We provide comparative diagnoses, redescriptions, illustrated identification keys, new geographical records, and designate needed neotypes for Megachile cara Mitchell, M. gigas Schrottky ...

Radical Social Ecology As Deep Pragmatism: A Call To The Abolition Of Systemic Dissonance And The Minimization Of Entropic Chaos, Arielle Brender May 2018

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 ...

T Socio-Ecology Of Managed Honeybees (Apis Mellifera) In The Louisville Metro Area., Haileigh M. Arnold

Electronic Theses and Dissertations

Humans have a long history of the practice of beekeeping to harness the power of pollination. This managed pollinator system consists of beekeepers, honeybees, and their environment. However, recent disease, pesticide use, and land use factors honeybee threaten this relationship. In the face of such concerns it is important to examine the factors that impact and can help sustain our managed pollinator systems. In this thesis, the national and Kentucky state-level policies that affect managed pollinator systems were examined and socio-ecological factors that may contribute to honeybee hive growth and losses were assessed along an urban development gradient in Louisville ...

The Effect Of Three Different Mulches On Weed Presence, Soil Characteristics, And Zinnia Growth, Anmar Muttaleb

Murray State Theses and Dissertations

Abstract

Organic and inorganic mulching helps to control weeds. Mulching helps cultivated plants to grow by inhibiting the growth of weeds, retaining soil moisture, and regulating the temperature of soil. The objective of this study was to determine the effects of different organic mulches on weed presence, soil characteristics, and growth of Zinnia elegans. The mulches used in studying Zinnia elegans were wheat straw, non-shredded Miscanthus (M. × giganteus), and shredded Miscanthus (M. × giganteus) mulch. A Randomized Complete Block Design (RCBD) was used in the study, with different quantitative methods were used to collect data. ANOVA tests were utilized to statistically ...

Honey, We Killed The Bees: Effectiveness Of U.S. Federal, State And Municipal Neonicotinoid Policies In Mitigating Managed Honey Bee Colony Loss, Rose Briggs Jan 2018

Honey, We Killed The Bees: Effectiveness Of U.S. Federal, State And Municipal Neonicotinoid Policies In Mitigating Managed Honey Bee Colony Loss, Rose Briggs

Undergraduate Honors Theses

This thesis analyzes existing policies regulating neonicotinoids at the federal, state, and municipal levels of the United States government. The research question examines effectiveness of these policies in mitigating honey bee colony loss among managed colonies within the U.S. Through a policy analysis, as well as a survey of beekeepers in Colorado, Oregon and New Mexico, existing policies are found to be ineffective in their approach, due to multiple loopholes and legal obstacles. This paper finds that while there are many stressors contributing to colony loss in the U.S., neonicotinoids have been found to harm honey bees significantly ...

A Performance Study Of Apis Mellifera With Dietary And Forage Restrictions During Spring Colony Establishment In Lyon County, Kentucky, Dominique Wood Jan 2017

A Performance Study Of Apis Mellifera With Dietary And Forage Restrictions During Spring Colony Establishment In Lyon County, Kentucky, Dominique Wood

Murray State Theses and Dissertations

One-third of our worldwide fruit, nut and vegetable production is completely dependent on the existence of pollinators. Commercial honey bees, Apis mellifera, have an annual economic value of $15 billion in the U.S. Additionally, their honey is valued at $150 million annually. In Fall 2006, commercial beekeepers observed sudden mass disappearances of whole colonies. By Spring 2007, the condition, dubbed Colony Collapse Disorder (CCD), raised environmental and fiscal concerns while the cause(s) continued to be sought. Forensic examinations of hive samples did not reveal a singular cause of CCD. The results pointed to a collection of detrimental factors ...

Why We Still Need To Worry About Bees, Meaghan Lee Callaghan Dec 2016

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.

Soil-Water Transport Of A Seed Coated Neonicotinoid Pesticide In Soybean/Maize Cultivation Systems, Geoffrey Nathaniel Duesterbeck Aug 2016

Soil-Water Transport Of A Seed Coated Neonicotinoid Pesticide In Soybean/Maize Cultivation Systems, Geoffrey Nathaniel Duesterbeck

Masters Theses

The current decline of the honey bee (Apis mellifera L.) and other beneficial pollinator species is well documented. Several causes have been cited in this decline including: pathogens, pests, nutrition, and pesticide exposure. Since the advent of the neonicotinoid family of pesticides in the 1990’s an increase in honey bee colony loss has been observed. Neonicotinoid pesticides are commonly applied as a seed treatment to cotton, soybean and maize row crops. As the seed germinates, it absorbs the pesticide from the coating then spreads systemically throughout the entire plant. However, a large portion of the seed coating may stay ...

A Plan For Pollinator Landscape Management On The Ursinus Campus, Megan N. Hanscom

Environmental Studies Honors Papers

Due to increased pollinator decline over the past decade, colleges and universities are developing pollinator management plans to help combat pollinator loss. Pollinators, and more specifically bees, are vital members of local ecosystems and protection efforts are greatly needed. This plan was created to address the needs of Ursinus College pollinators using relevant suggestions from pollinator research and existing protection plans. This plan includes suggestions for increased pollinator habitat on campus, ways to reduce pollinator stressors, and ways that the Ursinus community can positively impact pollinator health.


Ecological Risks Of The Conventional Insecticide/Fungicide Seed Treatment Mixture Of Thiamethoxam And Mefenoxam In Soybean On Beneficial Insects, Carolina Camargo Apr 2016

Ecological Risks Of The Conventional Insecticide/Fungicide Seed Treatment Mixture Of Thiamethoxam And Mefenoxam In Soybean On Beneficial Insects, Carolina Camargo

Dissertations and Student Research in Entomology

The impact of neonicotinoid seed treatments on beneficial insects has been a controversial topic during the last years. While neonicotinoids are usually used as mixtures with systemic fungicides, few studies have examined the impact of the mixtures on beneficial insects. Pesticide mixtures can have synergistic, additive, or antagonistic effects on the toxicity of neonicotinoids on non-target species.

Thiamethoxam with mefenoxam is the most used neonicotinoid insecticide/fungicide mixture applied to soybean. Based on the systemic nature of thiamethoxam and mefenoxam, residues of this insecticide/fungicide mixture can be present in soybean vegetative and floral tissue with potential impacts to beneficial ...

The Enhancement Of Wild Bees (Hymenoptera: Apoidea) For Pollination Security, Eric M. Venturini Aug 2015

The Enhancement Of Wild Bees (Hymenoptera: Apoidea) For Pollination Security, Eric M. Venturini

Electronic Theses and Dissertations

The acreage of pollinator-dependent crops continues to expand across the globe. Simultaneously, honey bee hives – an annually rented commodity that growers rely on – are more expensive every year and in some cases, scarce. In response, pollinator-dependent growers seek alternative pollinators. One approach is installing bee pasture on farms, a strategy that enables systems-based farmers to become in-situ farm-scale habitat managers. This thesis first presents a review of the literature on bee pasture plantings and provides a brief overview of some methods for assessing their impacts on the pollinator community. There are three major gaps in current bee pasture research. First ...


Honey Bees’ Impact On The U.S. Economy, James T. Chisel Jul 2015

Honey Bees’ Impact On The U.S. Economy, James T. Chisel

Economics Theses

Since Colony Collapse Disorder became front-page news in 2006, popular literature ranging from news articles to White House documents has cited the value that honey bees provide. These numbers in articles often are inconsistent and rarely cite the origin of the stated value. This paper examines the major studies on the economic impact that honey bees have in the United States. Then it discusses the existing errors in these studies’ methodologies and offers a preliminary model that incorporates the full economic effects of honey bees. It then offers some policy suggestions in order to better address the needs of honey ...

Using Video-Tracking To Assess Sublethal Effects Of Pesticides On Honey Bees (Apis Mellifera L.), Bethany S. Teeters, Reed M. Johnson, Marion D. Ellis, Blair D. Siegfried Jan 2012

Using Video-Tracking To Assess Sublethal Effects Of Pesticides On Honey Bees (Apis Mellifera L.), Bethany S. Teeters, Reed M. Johnson, Marion D. Ellis, Blair D. Siegfried

Faculty Publications: Department of Entomology

Concern about the role of pesticides in honey bee decline has highlighted the need to examine the effects of sublethal exposure on bee behaviors. The video-tracking system EthoVisionXT (Noldus Information Technologies) was used to measure the effects of sublethal exposure to tau-fluvalinate and imidacloprid on honey bee locomotion, interactions, and time spent near a food source over a 24-h observation period. Bees were either treated topically with 0.3, 1.5, and 3 μg tau-fluvalinate or exposed to 0.05, 0.5, 5.0, 50, and 500 ppb imidacloprid in a sugar agar cube. Tau-fluvalinate caused a significant reduction in ...
