Influence Of Temperature On The Tensile Strength Of Spider Silk (Araneus Gemmoides), Victoria Lekson
Influence Of Temperature On The Tensile Strength Of Spider Silk (Araneus Gemmoides), Victoria Lekson
Seaver College Research And Scholarly Achievement Symposium
Temperature ranges between day and night in southern California can be as great as 30°C and may influence vital functioning of ectothermic organisms. Arachnids produce silks from a pair of spinnerets in their abdomen and rely on variance in protein composition to make different types of silks. Temperature may influence tensile strength of filaments. We tested the effects of temperature on tensile strength of dragline silk of five specimens of Araneus gemmoides (orb-weaver) which were collected from Malibu Creek State Park in the Santa Monica Mountains of southern California, under five temperature conditions. Each specimen was placed in a 0.0283 …
P-27 Factors Affecting Phonotactic Responses In Male Acheta Domesticus, Erik Thordarson
P-27 Factors Affecting Phonotactic Responses In Male Acheta Domesticus, Erik Thordarson
Honors Scholars & Undergraduate Research Poster Symposium Programs
This research addresses some of the possible factors that affect male Acheta domesticus phonotactic responses to calls of males of the same species. The study examines cricket age and social interaction with females as possible factors affecting this behavior. Through logistic regression analysis, the study attempts to demonstrate a link between these factors and the responsiveness of the male crickets in the study. As the crickets aged, they responded to a wider range of syllable periods, which may imply that they follow a similar pattern of decreasing selectivity in their response with age as their female counterparts. The socialization aspect …
