Color Vision And Signal Color Evolution In Anolis Lizards, Catherine S. Wadman
Color Vision And Signal Color Evolution In Anolis Lizards, Catherine S. Wadman
Honors Theses
Anolis is a diverse genus of small arboreal lizards that utilize a visual communication system using a colorful expandable throat-fan (dewlap). They signal either to attract females or repel males. The environment the lizard lives in has influenced the coloring of these dewlaps. Species that occupy shaded habitats tend to have yellow dewlaps while those that inhabit brighter habitats tend to have red dewlaps. In experiment 1 we used a color perception assay to test whether a red or yellow stimulus against a green background was more visible to the lizard under different light intensities mimicking a dewlap appearing in …
Investigating The Relationship Between Invasive Garlic Mustard Alliaria Petiolata And Blacklegged Ticks Ixodes Scapularis, Nicole Shauffer
Investigating The Relationship Between Invasive Garlic Mustard Alliaria Petiolata And Blacklegged Ticks Ixodes Scapularis, Nicole Shauffer
Honors Theses
Garlic mustard Alliaria petiolata is an invasive herb that has been studied for its chemical allelopathy ability to hinder plant growth of its competitors and potential to inhibit entomopathogenic fungi. It has been suggested that these fungi which infect and kill insects and arthropods like blacklegged ticks Ixodes scapularis may be negatively impacted by garlic mustard presence. This study investigated the potential relationship between garlic mustard and blacklegged tick populations through two experiments. One experiment measured the effect of garlic mustard soil and leaf extract on waxworm survival where waxworms were used as a bioassay for the presence of fungi. …
