  1. Examining Mindfulness Meditation Focused-Attention With the MBAS and Solving Anagrams

    Black, Katharine
    As part of a programmatic line of research, we examined whether a brief mindfulness meditation training with the Meditation Breath Attention Scores (MBAS; Frewen, Evans, Maraj, Dozois, & Partridge, 2008: Frewen, Lundberg, MacKinley, & Wrath, 2011) enhanced anagram-solving performance. Current results replicated earlier findings of improved anagram performance following the MBAS. Participants solved two sets of 15 anagrams separated by the MBAS. We randomized students into either an MBAS-expectancy or MBAS-no expectancy condition. In order to examine the effects of our expectancy manipulation on anagram solving performance, those in our MBAS-expectancy group were told that they would be able to...

  2. Effectiveness of Predator Guards on Nest Boxes for House Wrens

    Ahrns, Megan
    Predation limits reproduction and survival in many animals. Some bird species protect their eggs by laying them in cavities, limiting the predators’ access to the nest. Nesting boxes are often used to increase the nesting opportunities of cavity-nesting birds, but they are susceptible to predators. We tested the effectiveness of three types of predator guards relative to a control (no predator guard): “extension” of the entrance to prevent predators from reaching into the nest box, “tube” which prevents predators from getting a grip on the pole, and a “funnel” which predators cannot proceed past. We predicted that the funnel guard...

  3. Do Male House Wrens (Troglodytes aedon) Vary Their Singing Among Various Reproductive Stages?

    Sackinger, Nathaniel
    The vocalizations of male songbirds can function in attracting mates and in defending territory. If song were used for attracting a mate, song output should decline following pairing. If song were used primarily for territory defense, song output should be constant throughout reproduction, because territories are maintained throughout multiple reproductive attempts within one breeding season. If song were used for communicating an ’all clear‘ signal, song output would be highest during incubation, when females are spending the most time on the nest. The purpose of this study was to determine whether the song of male House Wrens (Troglodytes aedon) changes...

  4. Habitat Characteristics Associated with Nest Site Selection and Reproductive Success of House Wrens (Troglodytes aedon)

    Khan, Mohammad
    Habitat characteristics influence the survival and reproduction of animal species. House Wrens (Troglodytes aedon) are an abundant species of songbird, are tolerant of humans, and nest readily in artificial nest boxes. We hypothesized that House Wrens would attempt more nests, raise more young, and feed their young more frequently in areas that contained more natural vegetation. Nesting boxes were placed in three habitats (100-123 boxes per year): a woodland area, a golf course, and a residential area. We quantified habitat characteristics within 15m of a nest box: % canopy cover, % shrub cover, % natural grass cover, % mowed grass...

  5. Seasonal Variation in the Song of Male House Wrens (Troglodytes aedon)

    Schafer, Kristin
    In songbirds, male song is a major component of courtship display and mate attraction. Previous studies suggest that male song may serve to attract females for extra-pair copulations, during which a mated male seeks additional females for mating purposes outside of the pair bond. If song is used to attract additional mates, the song output of the male bird should fluctuate very little throughout the breeding cycle. The purpose of this study was to determine how the song of male house wrens (Troglodytes aedon) fluctuates throughout the breeding season. House wrens are socially monogamous, but have high levels of extra-pair...

  6. After the Bureau: The Rise of African-American Debt Peonage and Convict Labor in the South following Reconstruction

    Nutt, Rebecca
    During Reconstruction, the Freedmen’s Bureau had the opportunity to effect significant change for the betterment of the southern African-American population. As a political and social voice for the freedmen, the Bureau provided temporary education management, labor support, legal representation and other services. As this study argues, the system began effectively and had the potential to establish a long-term agency that could have addressed the labor issues of African Americans well into the twentieth century. With its early demise in 1872 however, Congress closed up the Bureau, thereby, tacitly condoning the rising exploitive labor practices of debt peonage and convict leasing...
