Abstract In this study I examined ant biodiversity in Alberta. Over a two-year period, 41,791 ants were captured in pitfall traps on five sand hills in central Alberta and one adjacent aspen parkland community. Using additional collections, I produced a key to the 92 species of ants known from Alberta, Canada. The central Alberta sand hills had the highest recorded species richness (S = 35) reported in western Canada with local ant species richness inversely related to canopy cover. Forest fires occurred in the sand hills during both years of sampling, allowing me to examine the response of ants to fire. Species richness did not significantly change following fire, although individual species did change in abundance. Body size was the most influential variable in predicting changes in species abundance. This study underscores that ants in Alberta are more species-rich and have complex adaptations to disturbance. Acknowledgements I would like to thank my supervisors, Dr. Scott Nielsen and John Acorn for supporting me and helping me through the difficult process of constructing, testing, and writing a thesis. I also thank my committee member Dr. John Spence for comments, advice, and encouragement throughout my project. I would like to thank my examining committee member Dr. Heather Proctor for her support and help.

  • Social Parasitism in Ant and Human Societies
    POLITICAL PSYCHOLOGY POL358 Social Parasitism in Ant and Human Societies Joseph Marcel Virassamy 4/10/2013 Contents Introduction 1. Types of Parasitic Life History: Emery’s Rule 2. Temporary Parasitism: Concept of Power 3. Permanent Inquilines: Free Rider 4. Slave-making: Work Force 5. Recommendations and conclusion 6. Research Question: In what ways and for what reasons do social parasites manipulate their host? 7. Hypotheses: I would argue that social parasitism, whether in humans or ants societies, is based partly on self-interest and nature. Introduction This paper will attempt to bring to light a new study proposed by Professor Anil Hira in the field of bioeconomics studies. Though other nonhuman social societies, such as honeybees, can be used to draw parallels to human societies, in this paper I will focus specifically on ant social societies that are more “than a hundred million years older than humans” (Gordon, 2010, p.1). The reason I have decided to study ants and human societies is because both societies are the two most successful social organizations on the planet. Ants are one of the “most highly social of all organisms” (Wilson, 1991, p. 14) and dominate the insect world. Furthermore, like humans, ants succeed because they communicate effectively and efficiently (Hölldobler & Wilson, 1994). There is abundant literature on biological studies of ants; in the research for this literature review, I have selected some noteworthy literature on ant behaviour that I believe will 1 help to initiate a discussion on ant behaviour. The literature review includes the work of Hölldobler & Wilson, 1994, 2011; Gordon, 1999, 2010; Sudd, 1967; Moffett, 2010; Bourke & Franks, 1995; Hugh, 1967; Abbott, Lach & Parr, 2010; Gotwald, 1995 and Deslippe, 2010.

Bacterial endosymbionts are common across insects, but we often lack a deeper knowledge of their prevalence across most organisms. Next-generation sequencing approaches can characterize bacterial diversity associated with a host and at the same time facilitate the fast and simultaneous screening of infectious bacteria. In this study, we used 16S rRNA tag encoded amplicon pyrosequencing to survey bacterial communities of 310 samples representing 221 individuals, 176 colonies and 95 species of ants. We found three distinct endosymbiont groups—Wolbachia (Alphaproteobacteria: Rickettsiales), Spiroplasma (Firmicutes: Entomoplasmatales),
