BOSTWICK, Kimberly; Cornell University: How do the feathers of the Club-winged Manakin (Aves: Pipridae) produce a sustained note composed of integer-related harmonics? In 1871 Darwin noted that in the context of intense sexual selection during courtship displays the anatomy of male birds was occasionally modified to enable the production of non-vocally produced acoustic signals, or […]

Effect of Resource Enrichment on the Social Structures of Crayfish
DICKEY, Brad; University of Kentucky, Lexington; University of California, Davis: Effect of Resource Enrichment on the Social Structures of Crayfish Social structures affect access to resources such as shelters and food, but changes in the environment affect the dynamics of the social structure and the behaviors of the group members. These reciprocal effects make it […]
Do threat displays in lizards handicap endurance by interfering with respiration
BRANDT, Y*; CHAPPELL, MA; University of Toronto at Scarborough; University of California, Riverside: Do threat displays in lizards handicap endurance by interfering with respiration? Threat displays, the signals employed in agonistic interactions, appear to advertise aggression and fighting prowess. Handicaps, signals whose honesty is maintained by the cost of signal production, are seldom employed as […]
Blue petrel (Halobaena caerulea) fledglings respond differently to a food-related odor and a novel odor in a wind tunnel
CUNNINGHAM, Gregory B.; WEIMERSKIRCH, Henri; NEVITT, Gabrielle A.; Univ. of California, Davis; CNRS, France; Univ. of California, Davis: Blue petrel (Halobaena caerulea) fledglings respond differently to a food-related odor and a novel odor in a wind tunnel. In a first step towards understanding the ontogeny of olfactory foraging behaviors in Antarctic procellariiform seabirds, we showed […]
Aquatic chemoreception in loggerhead sea turtles behavioral responses to food and a novel chemical
SOUTHWOOD, A.L.*; HIGGINS, B.M.; BRILL, R.W.; SWIMMER, J.Y.; University of Hawaii; NOAA Fisheries; NOAA Fisheries; NOAA Fisheries: Aquatic chemoreception in loggerhead sea turtles: behavioral responses to food and a novel chemical We developed an assay to investigate the behavioral responses of loggerhead sea turtles, Caretta caretta, to chemical stimuli presented underwater. Captive-reared juvenile loggerhead turtles […]

Stress-Induced Disruption of Brain Development and Learning Ability In Drosophila
ROBERTS, S.P.*; WANG, X.; GREEN, D.S.; DE BELLE, J.S.; Univ. of Nevada Las Vegas; Univ. of Nevada Las Vegas; Univ. of Nevada Las Vegas; Univ. of Nevada Las Vegas: Stress-Induced Disruption of Brain Development and Learning Ability In Drosophila Environmental stress exposure (nutritive, chemical, electromagnetic and thermal) has been shown to disrupt CNS development in […]
Odor conditioning success differs between nurse and forager bumblebees
SATTLER, A.L.*; FOSTER, R.L.; HANNAFORD, S.; Univ. of Puget Sound; Univ. of Puget Sound; Univ. of Puget Sound: Odor conditioning success differs between nurse and forager bumblebees Classical conditioning of the proboscis extension reflex (PER) is a common laboratory paradigm for studying mechanisms of learning in insects, but has only recently been applied to odor […]
Mechanical forces on the antennae of a flying insects
SANE, SP; DIEUDONNE, A; WILLIS, MA; DANIEL, TL; University of Washington; University of Washington; Case Western Reserve University; University of Washington: Mechanical forces on the antennae of a flying insects Insect antennae are equipped with two sets of mechanosensory fields in their basal segments.One set, the Bohm’s bristles, are arranged as bristle fields on the […]
How Syrian hamsters fill their cheek pouches Co-opted masticatory motor patterns and the role of the retractor muscle
BUCKLEY, C.A.*; SCHNEIDER, J.E.; CUNDALL, D.; Lehigh University: How Syrian hamsters fill their cheek pouches: Co-opted masticatory motor patterns and the role of the retractor muscle The rodent cheek pouch is an evolutionary novelty that allows quick transport of large amounts of food to a safe environment for storage and consumption. Hamsters are unusual in […]
