    A Debate on Skepticism and Perceptual Belief

    No full text
    This chapter consists of five exchanges between Annalisa Coliva, Anil Gupta, and Crispin Wright. These philosophers debate a wide range of issues including (i) whether perceptual judgments presuppose general hinge propositions (e.g., “External objects are, by and large, as they appear to be”); (ii) whether the justification of perceptual judgments requires that the hinge propositions be justified; (iii) whether the idea of hinge proposition helps address skeptical arguments; and (iv) which skeptical arguments deserve a constructive response and which deserve to be dismissed as fallacious

    The 8 data and code files in this archive accompany the manuscript "Studying mate preferences using inertial measurement units: A validation study with treefrogs"Investigations of mate choice continue to address fundamental questions about the mechanisms and evolution of animal behaviour. A common behavioural assay used to study acoustically guided mate choice with playback experiments is phonotaxis, a typically robust response in which a chooser approaches a sound source broadcasting acoustic signals, such as courtship songs or mating calls. Robust empirical studies of phonotaxis often require substantial laboratory facilities, such as a dedicated and sound-treated room or enclosure, in which the acoustic environment is controlled and in which animals are freely able to move about. The financial and space resources required to outfit a research laboratory to investigate phonotaxis may be sufficiently prohibitive such that some researchers are excluded from undertaking bioacoustic behavioural research. Here, we validate a new device designed to measure animal movements related to phonotaxis behaviour using an inertial measurement unit (IMU). The device is small and portable; it can be constructed for less than $300 US dollars; and the build instructions and code for operation are freely available (Gupta et al., 2020, HardwareX, 8, e00116). In a series of four experiments with treefrogs, we demonstrate using the device that an IMU-based approach to measuring animal movement can replicate a broad range of findings from traditional phonotaxis experiments on species recognition and sexual selection. We conclude by discussing several possible uses for IMU-based measurements of phonotaxis.National Science FoundationGupta, Saumya; Bee, Mark A. (2023).

    Charops plautus Gupta & Maheshwary from host Udaspes folus (Cramer) (Figs. 17, 18 & 19) The solitary pupal parasitoid Charops plautus Gupta & Maheshwary was reared from the host Udaspes folus Gupta & Maheshwary (1970). No male specimens were bred and the species was identified based on females. Udaspes folus is the first host record of the parasitic wasp genus Charops. Brief diagnosis: This species has following characters: scape and pedicel ventrally yellow; tegula pale yellow. Mesopleuron reticulate rugose; malar space 0.7 × basal width of mandible; inter-ocellar distance 3 × ocello-ocellar distance; fore coxa with a mix of black and yellow patches; trochanter pale yellow and femur yellow brown medially; tarsus pale yellow. Mid leg with coxa black; trachanter pale yellow; femur yellow brown with very faint black infuscation on dorso-apical region. Hind leg with coxa black; femur yellow brown with a black patch ventrally in basal half; hind tibia yellow brown with apical 1 / 4 th black; tarsi brown with basitarsus darker; tibial spurs pale yellow. Metasoma with petiole black except at extreme apical region. Second tergite yellow brown with apical margin black; rest metasoma yellowish brown. Specimens examined: Two females, Powai, IIT-Bombay, Mumbai, Maharashtra, India; 19.12 °N 72.91 °E, elevation 50 m (160 ft), 22.ix. 2012, bred from pupa of U. folus (Grass Demon) (Lepidoptera: Hesperiidae), coll.
