  1. 1. Analyzing the use of Humidity Cue in Navigation of Drosophila melanogaster

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Kalle Andersson; [2022]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Humidity is one of the main abiotic factor of ecosystems and affects animals behaviour, fitness and distribution. Due to their small size and inability to thermoregulate using metabolism, insects, such as the fruit fly Drosophila Melanogaster, are especially reliant on humidity. LÄS MER

  3. 2. Comparing listeners’ ability to detect and lateralize simulated sound reflections

    Master-uppsats, Stockholms universitet/Psykologiska institutionen

    Författare :Freja Isohanni (fd Kempe); [2019]
    Nyckelord :Psychology; Psychophysics; Psychoacoustics; Human echolocation;

    Sammanfattning : Echolocation is using lagging sounds as cues to localize the objects reflecting them. The precedence effect (PE) occurs when echoic signals are suppressed in favour of leading signals. In this study, the ability of nine listeners to overcome the PE when detecting and lateralizing echoic signals through headphones was measured and compared. LÄS MER

  4. 3. Evaluation of an automatic system for measuring human echolocation ability

    Kandidat-uppsats, Stockholms universitet/Psykologiska institutionen

    Författare :Jennie Lagerstedt; [2018]
    Nyckelord :Echolocation;

    Sammanfattning : To measure thresholds of human echolocation ability researchers need an automated system for the possibility to present a large set of stimuli. Previous studies have used recorded sounds or simulated sounds, allowing strict stimulus control at the expense of ecological validity. LÄS MER

  7. 5. Evaluation of live fish as an echolocation enrichment for the bottlenose dolphin (Tursiops truncatus)

    Master-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

    Författare :Veronika Karczmarz; [2016]
    Nyckelord :Echolocation; Bottlenose dolphins; Sonar; Enrichment; Live fish; Goldfish; Welfare; Zoo animals;

    Sammanfattning : Bottlenose dolphins (Tursiops truncatus) kept in zoos and dolphinarias rarely get an outlet for their echolocation abilities as their pool environment is often quite barren. Not much research has been carried out on enrichments promoting echolocation for dolphins in human care. LÄS MER
