Storage and Utilization of Hexamerin Proteins in the Pitcher Plant Mosquito, Wyomyia Smithii
The acquisition of hexamerin proteins in the pitcher plant mosquito, Wyeomyia smithii shows a North-South cline in the southeastern United States. Adult female W. smithii in North Carolina are completely autogenous and larger in size (based on wing length). They are anautogenous in Florida and …

Characterization of winter microbial communities in the purple pitcher plant (<i>sarracenia purpurea</i>)
<p>Carnivorous pitcher plants trap insects in cone-shaped leaves and digest them to gain vital nutrients. For digestion to occur, plants in the genus <em>Sarracenia</em> require mutualistic microorganisms living in their leaves. Few studies have examined how these communities change over time. This …
