The black widow’s hourglass a covert aposematic signal
Meeting Abstract 99.2 Saturday, Jan. 7 The black widow’s hourglass: a covert aposematic signal? BRANDLEY, N. C.*; JOHNSEN, S.; Duke University ncb9@duke.edu While culturally iconic, the hourglass of the American black widows (Latrodectus hesperus, L. mactans, and L. variolus) is scientifically unstudied. The hourglass’ color and orientation suggest that it is an aposematic signal to avian predators. […]
Predation in the strawberry poison frog Oophaga pumilio Are adults and juveniles equally protected from ctenid spiders
Meeting Abstract 99.3 Saturday, Jan. 7 Predation in the strawberry poison frog Oophaga pumilio: Are adults and juveniles equally protected from ctenid spiders? MURRAY, Erin M.*; SAPORITO, Ralph A.; Missouri State University; John Carroll University Erin1989@live.missouristate.edu Many organisms possess defensive mechanisms to protect themselves from predation. Dendrobatid frogs, such as Oophaga pumilio, contain alkaloid chemical defenses and […]
Luminescent responses to predation in the scale worm Harmothoe imbricata
Meeting Abstract 99.1 Saturday, Jan. 7 Luminescent responses to predation in the scale worm Harmothoe imbricata RIVERS, TJ*; PERREAULT, TR; Bowdoin College; Bowdoin College trivers@bowdoin.edu Bioluminescence is a phenomenon that has evolved many different times in many different organisms, especially in marine systems. For all that is known about how many of these species luminesce (physiologically and […]
Does predation by leeches inferred from chemical cues impose any appreciable costs on their snail prey
Meeting Abstract 99.4 Saturday, Jan. 7 Does predation by leeches inferred from chemical cues impose any appreciable costs on their snail prey? WETHINGTON, A R; Chowan University wethia@chowan.edu Physa acuta, a prominent member of freshwater ecosystems, is known to have morphological, life history, and behavioral responses to both fish and crayfish predators. However, less is known about […]
Behavioral sensitivity of batoid elasmobranchs to prey-simulating electric fields
Meeting Abstract 99.5 Saturday, Jan. 7 Behavioral sensitivity of batoid elasmobranchs to prey-simulating electric fields BEDORE, CN*; HARRIS, LL; KAJIURA, SM; Florida Atlantic University; Florida Atlantic University; Florida Atlantic University bedorech@gmail.com Elasmobranchs are renowned for their electrosensory capabilities and sensitivity to electric fields has been quantified for numerous species. However, tremendous diversity in morphology, behavior, and habitat […]
