Water Lily Leaf Beetle Ecology On Hourglass Lake In Big Lake, Alaska, Haley Lloyd, Grace Beatty
Scholar Week 2016 - present
The Water-Lily Leaf beetle, Galerucella nymphaeae, is a beetle commonly found on Western Pond Lily pads, Nuphar lutea, in Hourglass Lake. Hourglass Lake is located in Big Lake, Alaska. This area is surrounded by boreal forest and bogs and is situated roughly twenty miles North of Anchorage. Within this ecosystem, the Water-Lily Leaf Beetle and the Western Pond Lily are intrinsically linked, as the lily pads serve as a site of feeding and reproduction for the beetles. Dr. Derek Rosenberger of Olivet Nazarene University noticed an abundance of these beetles as he was kayaking through Hourglass Lake, and a project …

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 …
