Carrion-associated arthropods in rural and urban environments
<p>Preferences of arthropods are important in forensic entomology, as the species collected can help determine the postmortem interval or if remains have been moved. This study looked at arthropods that are attracted to pig carcasses in rural and urban habitats in Northwest Indiana. The species and …

The influence of epiphytes on arthropods in the tropical forest canopy
… in tree crowns. In total, more than 277,000 arthropods were collected and about 700 morphospecies determined. Epiphytes had a significant moderating influence on canopy microclimate (Chapter 3), both at various microsites within a tree crown and among tree crowns with different epiphyte …

Evolution and Anatomy of Early Terrestrial Arthropods: Insights from the Rhynie Chert
… anatomical and functional adaptations of Rhynie arthropods, addressing key questions about the evolution of arthropod terrestrialisation and the morphological innovations that enabled life to proliferate on land. Through detailed analyses, this research examines the functional morphology and …

Regulation of segment polarity genes in the head region of different arthropods
Head segmentation in insects, as reflected by the model system Drosophila melanogaster, is less well understood in comparison to the trunk. While the gnathal segments (mandibular, maxillary, labial) are patterned in a way similar to the trunk, distinct molecular mechanisms underlie the …

Ground - dwelling arthropods in a biosphere reserve: patterns of diversity and conservation implications
Invertebrate diversity is often neglected in conservation planning initiatives. There are also very few large-scale diversity studies in Africa, with most studies being restricted to single properties and spatial extents that are on average not much larger than 30 km2. Here, we provide a …

Internal structure and chemical composition of arthropods from Early Miocene Dominican Republic amber
Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2027-08-01

Investigating the functional and evolutionary significance of Group B Sox genes in arthropods
Group B Sox genes play a critical developmental role in both vertebrates and insects. Within the model species Drosophila melanogaster, two SoxB genes, Dichaete and SoxNeuro, have been shown to act as ‘master regulators’ in the early development of the central nervous system. SoxB genes have only …

Comparing University Entomology Outreach Events While Examining Public Views of Arthropods and Pesticides
… better public perceptions of insects and other arthropods, and educate participants about pesticide safety and pest management practices. Although many institutions host entomology outreach events like Hokie BugFest (Frazier, 2002; Hamm and Rayor, 2007; Hvenegaard et al., 2013), little research …

Influence of living and non-living habitat complexity on arthropods in strip-tilled cabbage fields
… structural (non-living) complexity can influence arthropods in agricultural systems. In this thesis, both forms of complexity were manipulated in cabbage fields. In 2010 and 2011, a field experiment was conducted examining the effects of herbicide intensity and oat kill date on arthropods, weeds, …

Birds, pests, and beneficial arthropods in soybean following a fall-planted cereal rye cover crop
Submission original under an indefinite embargo labeled 'Open Access'. The submission was exported from vireo on 2022-11-11 without embargo terms

The effects of replanting and restoration of riparian buffers on arthropods in oil palm systems
… management. Across these plantations, we sampled arthropods in the canopy, understory, and ground microhabitats using insecticide fogging; sticky traps and hand collections; and pitfall traps, respectively. We sampled in different ages of oil palm, and in sites that were within, near, and far from …

Determination of the possible role of arthropods as vectors for "Potomac Horse Fever" in equines
… vectors. A seasonal activity study of biting arthropods attacking horses in endemic areas of Maryland and Virginia identified five potential vectors: (1) Simulium jenningsi (Diptera: Simuliidae), (2) Stomoxys calcitrans (Diptera: Muscidae), (3) Culicoides obsoletus (Diptera: Ceratopogonidae), …

Investigations into the vector competency of arthropods for two Ehrlichias: Ehrlichia risticii and Cowdria ruminantium
Three studies relating to the vector competency of several species of ticks and <i>Simulium</i> spp. (blackflies) for <i>Ehrlichia risticii</i>, causative agent of Potomac horse fever (PHF) and <i>Amblyomma variegatum</i> for <i>Cowdria ruminantium</i>, causative agent of heartwater, are described. …

Population genetic structures and dispersal patterns of arthropods in New Zealand and the Ross Dependency, Antarctica
… genetic structures and dispersal patterns of arthropods in two geographic regions-Antarctica and New Zealand-using molecular techniques in conjunction with distributional data and dispersal experiments. Regional genetic divergence was revealed using allozymes and mtDNA (COI) for populations of …

Responses of Arthropods to Fire and How Pollinators and Pollination Services Are Affected by Fire Severity
… essential ecosystem services. Focusing on arthropods, fire can influence this ubiquitous animal group in various way. We performed a comprehensive meta-analysis evaluating how fires impact differing arthropod functional groups. We found that overall, fire negatively effects community level …
