Meeting Abstract 15-8 Saturday, Jan. 4 11:45 – 12:00 Nectary size is a pollination syndrome trait in Penstemon KATZER, AM*; WESSINGER, CA; HILEMAN, LC; University of Kansas a681k477@ku.edu Individual trait adaptation can influence the evolution of complex phenotypes such as floral pollination syndromes. In Penstemon, hummingbird-adapted flowers have evolved many times from bee-adapted ancestors. We examined the […]

A global molecular phylogeny of chromosomal evolution in wild onions (Allium, Amaryllidaceae)
Meeting Abstract 15-5 Saturday, Jan. 4 11:00 – 11:15 A global molecular phylogeny of chromosomal evolution in wild onions (Allium, Amaryllidaceae) BABIN, CH*; BELL, CD; University of New Orleans; University of New Orleans chbabin@uno.edu Polyploidy, the event of increasing nuclear chromosomes, is believed to be a significant driver of diversification among land plants. Mechanisms of chromosome number […]

During normal physiological activity intramuscular fluid pressures develop as muscle […]
Tenacious Toes and Fastening Feet Biological Adhesive Systems in Complex Environments
Meeting Abstract 14-7 Saturday, Jan. 4 11:30 – 12:00 Tenacious Toes and Fastening Feet: Biological Adhesive Systems in Complex Environments STARK, AY; Villanova University alyssa.stark@villanova.edu http://www.alyssaystark.com Organisms that temporarily attach in order to move within their environment face potential failure with every step and release cycle. This potential for failure prompts unique morphological, biomechanical, and behavioral attachment […]
