Historical Biogeography Of Velvet Ants (Hymenoptera: Mutillidae) In The North American Deserts And Arid Lands, Joseph S. Wilson
Historical Biogeography Of Velvet Ants (Hymenoptera: Mutillidae) In The North American Deserts And Arid Lands, Joseph S. Wilson
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
For centuries, scientists have been intrigued by the high amount of biodiversity that is found in the deserts of North America. Recently, several studies have investigated the causes of the high diversity found in desert-dwelling mammals, reptiles, and amphibians. These studies have found that many of these organisms seem to have diversified in response to the same historical events. Little work has been done, however, on diverse desert-dwelling insect groups. In this dissertation, I investigate the patterns of genetic diversity in four groups of nocturnal wasps called velvet ants. I compare the patterns of genetic diversity to the historical events …
The First Hypogean Dipluran From Portugal: Description Of A New Species Of The Genus Litocampa (Diplura: Campodeidae), Ana Reboleira, Alberto Sendra, Fernando Gonçalves, Pedro Oromí
The First Hypogean Dipluran From Portugal: Description Of A New Species Of The Genus Litocampa (Diplura: Campodeidae), Ana Reboleira, Alberto Sendra, Fernando Gonçalves, Pedro Oromí
Ana Sofia P.S. Reboleira
A new species of subterranean Campodeid Dipluran of the genus Litocampa mendesi n. sp. is described. Despite the presence of this genus in Spain, this is the first record in Portugal, and it is also the first Portuguese species of hypogean Diplura. The new species combines unique characters absent in the European and American species of the genus. Litocampa mendesi n. sp. was collected only in one part of a cave of the Jurassic karstic massif of Algarve, the southwesternmost part of the Iberian Peninsula. The morphological features of this species show some adaptations to hypogean life but not a …

A Hypogean New Species Of Trechus Clairville, 1806 (Coleoptera, Carabidae) From Portugal And Considerations About The T. Fulvus Species Group, Ana Reboleira, Vicente Ortuño, Fernando Gonçalves, Pedro Oromí
Ana Sofia P.S. Reboleira
A new hypogean ground beetle species, Trechus tatai n. sp. from the Montejunto karstic massif in Portugal is described. Morphological diagnostic characters of the imago are provided and the new species is included in the Trechus fulvus-group. Comments on the biogeography of hypogean carabid beetles in karstic areas of Portugal and an illustrated key to the males of the T. fulvus-group in the Iberian Peninsula are also included.
Sperm Use During Egg Fertilization In The Honeybee (Apis Mellifera), Maria Rubinsky
Sperm Use During Egg Fertilization In The Honeybee (Apis Mellifera), Maria Rubinsky
Independent Study Project (ISP) Collection
A technique to quantify sperm use in honeybee queens (Apis mellifera) was developed and used to analyze the number of sperm used in different groups of honeybee queens. To do this a queen was placed on a frame with worker cells containing no eggs, and an excluder box was placed around her. The frame was put back into the colony and removed after two and a half hours. This method reduced stress on the queen so that she felt comfortable enough to lay eggs and did not require the queen to be killed so that she could be sampled multiple …
Description Of The Third Instar Larva Of A Hypogean Ground Beetle, Trechus Alicantinus (Coleoptera: Carabidae: Trechinae), Vicente Ortuño, Ana Reboleira
Description Of The Third Instar Larva Of A Hypogean Ground Beetle, Trechus Alicantinus (Coleoptera: Carabidae: Trechinae), Vicente Ortuño, Ana Reboleira
Ana Sofia P.S. Reboleira
Description and illustrations are provided for the third instar larva of Trechus alicantinus Español, 1971 obtained from a laboratory breeding. This paper aims to contribute to increase the general knowledge about microendemic hypogean species of the east of the Iberian Peninsula. Besides, it expands the existing knowledge about the preimaginal stages of the genus Trechus and the whole tribe Trechini (Coleoptera, Carabidae). Larvae can give additional information about the life style of the species. Larvae can also express, even more than the imagos, some apomorphic characters, traditionally considered a result of adaptation to the hypogean habitat, such as the regression …

First Report Of The House Fly Larvae, Musca Domestica (Linnaeus) (Diptera: Muscidae) Associated With The Monkey Carcass In Malaysia, Chen Chee Dhang
First Report Of The House Fly Larvae, Musca Domestica (Linnaeus) (Diptera: Muscidae) Associated With The Monkey Carcass In Malaysia, Chen Chee Dhang
Chen Chee Dhang
A study on insect succession of monkey carcass in a forested area in Ulu Gombak, Selangor, Malaysia was conducted from 9 May to 18 June 2007. The third instal: of the housefly, Musca domestica (Linnaeus) (Diptera: Muscidae) were only found on dry stage at a decomposed (Day-33) monkey carcass (Macaca fascicularis Raffles). This observation revealed that M. domestica maggots were found together with other muscid fly maggots, Hydrotaea (=Ophyra) spinigera (Stein) (Diptera: Muscidae) on dry stage of a carcass. However, the role of M. domestica on forensic entomological study remains unknown. This study recorded the first finding of M. domestica …
Environmental Correlates Of Abundances Of Mosquito Species And Stages In Discarded Vehicle Tires, Donald A. Yee, Jamie M. Kneitel, Steven A. Juliano
Environmental Correlates Of Abundances Of Mosquito Species And Stages In Discarded Vehicle Tires, Donald A. Yee, Jamie M. Kneitel, Steven A. Juliano
Faculty Publications – Biological Sciences
Discarded vehicle tires are a common habitat for container mosquito larvae, although the environmental factors that may control their presence or abundance within a tire are largely unknown. We sample discarded vehicle tires in six sites located within four counties of central Illinois during the spring and summer of 2006 to determine associations between a suite of environmental factors and community composition of container mosquitoes. Our goal was to find patterns of association between environmental factors and abundances of early and late instars. We hypothesized that environmental factors correlated with early instars would be indicative of oviposition cues, whereas environmental …
Catalog Of The Coreidae, Or Leaf-Footed Bugs, Of The New World, Richard J. Packauskas
Catalog Of The Coreidae, Or Leaf-Footed Bugs, Of The New World, Richard J. Packauskas
Fort Hays Studies Series
Studies on the New World Coreidae have languished for more than a century. Neglect of these often large, abundant, and occasionally economically important bugs has been due, I believe, to the lack of means to identify them. Most literature treating the New World Coreidae has been restricted to the North American fauna, except for the recent efforts of Brailovsky (1975 to 2007).
Genetic Variation For Susceptibility To Storm-Induced Stem Breakage In Solidago Altissima: The Role Of Stem Height And Morphology, M. Wise, W. Abrahamson
Genetic Variation For Susceptibility To Storm-Induced Stem Breakage In Solidago Altissima: The Role Of Stem Height And Morphology, M. Wise, W. Abrahamson
Warren G. Abrahamson, II
While storms can have obvious ecological impacts on plants, plants’ potential to respond evolutionarily to selection for increased resistance to storm damage has received little study. We took advantage of a thunderstorm with strong wind and hail to examine genetic variation for resistance to stem breakage in the herbaceous perennial Solidago altissima. The storm broke the apex of nearly 10% of 1883 marked ramets in a common-garden plot containing 26 genets of S. altissima. Plant genets varied 20-fold in resistance to breakage. Stem height was strongly correlated with resistance to breakage, with taller stems being significantly more susceptible. A stem’s …
Spatiotemporal Variation Of Fruit Digestible-Nutrient Production In Florida's Uplands, J. Layne, W. Abrahamson
Spatiotemporal Variation Of Fruit Digestible-Nutrient Production In Florida's Uplands, J. Layne, W. Abrahamson
Warren G. Abrahamson, II
We examined annual total digestible nutrient (TDN) production by fruits of eight species (Quercus chapmanii, Q. geminata, Q. inopina, Q. laevis, Q. myrtifolia, Carya floridana, Sabal etonia, Serenoa repens) that account for the major proportion of TDN production by fruits and seeds in Florida’s xeric upland associations (southern ridge sandhill, sand pine scrub, scrubby flatwoods). Mean annual fruit TDN of all species combined over a 27-year span in sandhill and scrub and 24 years in scrubby flatwoods was highest (45.4 kg/ha) in sandhill, intermediate in scrubby flatwoods (28.8 kg/ha), and lowest in scrub (14.2 kg/ha). Sandhill fruit TDN production was …
Ducking As The Means Of Resistance In "Candy-Cane" Stems Of Goldenrod: Straightened Stems Lose Their Edge, M. J. Wise, W. G. Abrahamson, J. A. Cole
Ducking As The Means Of Resistance In "Candy-Cane" Stems Of Goldenrod: Straightened Stems Lose Their Edge, M. J. Wise, W. G. Abrahamson, J. A. Cole
Warren G. Abrahamson, II
Herbivores are among the most pervasive selective forces acting on plants, and the number of plant chemicals that presumably evolved for defense against herbivory is immense. In contrast, biologists are only beginning to appreciate the important roles that architectural traits can play in antiherbivore defense. One putative architectural-resistance trait is the nodding stem apex of some goldenrods (Solidago ; Asteraceae). Individuals of S. altissima genets that undergo temporary nodding in the late spring (i.e., “candy-cane ramets) have been shown to be more resistant than individuals of erect-stemmed genets to certain apex-attacking” herbivores. We tested the hypothesis that the greater resistance …
Nutrition As A Facilitator Of Host-Race Formation: The Role Of Food Quality In The Shift Of A Stem-Boring Beetle To A Gall Host, C. P. Blair, R. V. Schlanger, S. E. Diamond, W. G. Abrahamson
Nutrition As A Facilitator Of Host-Race Formation: The Role Of Food Quality In The Shift Of A Stem-Boring Beetle To A Gall Host, C. P. Blair, R. V. Schlanger, S. E. Diamond, W. G. Abrahamson
Warren G. Abrahamson, II
1. The importance of host-race formation to herbivorous insect diversity depends on the likelihood that successful populations can be established on a new plant host. A previously unexplored ecological aid to success on a novel host is better nutritional quality. The role of nutrition was examined in the shift of the stem-boring beetle Mordellistena convicta to fly-induced galls on goldenrod and the establishment there of a genetically distinct gall host race. 2. First, larvae of the host race inhabiting stems of Solidago gigantea were transplanted into stems and galls of greenhouse-grown S. gigantea plants. At the end of larval development, …
Polyphyly Of The Pikeminnows (Teleostei: Cyprinidae) Inferred Using Mitochondrial Dna Sequences, T. Heath Ogden
Polyphyly Of The Pikeminnows (Teleostei: Cyprinidae) Inferred Using Mitochondrial Dna Sequences, T. Heath Ogden
T. Heath Ogden
The phylogenetic relationships of the Colorado pikeminnow Ptychocheilus lucius, northern pikeminnow P. oregonensis, Sacramento pikeminnow P. grandis, Umpqua pikeminnow P. umpquae, and hardhead Mylopharodon conocephalus were examined by using molecular data to investigate monophyly of the genus Ptychocheilus. Phylogenies generated using DNA sequence data from the cytochrome b and 16S ribosomal DNA genes of the mitochondrial genome reveal that Ptychocheilus is a polyphyletic genus and suggest that the taxonomy of the group is in need of further revision. These data yield insights into the evolution of the pikeminnows and help place the significant evolutionary events in context with the geological …
