TAMMERO,L.F.*; DICKINSON,M.H.: The Pattern of Optic Flow Determines Flight Behavior in Freely Flying Drosophila While flying through its environment in search of food, a fruitfly (Drosophila) must integrate input from several sensory modalities. To study the behavioral patterns that emerge from the interactions of these sensory systems, we reconstructed three-dimensional trajectories from images taken by […]

THEOBALD, J.C.*; O’CARROLL, D.: Neural strategies that optimize motion detection in the crepuscular hawkmoth Manduca sexta Perhaps the greatest demand on visual system design occurs with the transition from day to night, since illuminance can differ by a factor of 108. For an animal to function in darker conditions, its visual system must deal with […]

FRYE, M.A.*; DANIEL, T.L.: Mechanical encoding properties of the wing hinge stretch receptor in the hawkmoth Insect flight emerges from complex interactions among patterned motor output, musculoskeletal mechanics, aerodynamic and inertial forces, and neural feedback. In the hawkmoth Manduca sexta, feedback from a wing hinge stretch receptor (SR) is crucial for the visuo-motor control of […]

SCOTT, M.P.: Hormonally-Mediated Cues for Mate Recognition by Burying Beetles Individual recognition of a mate or a past enemy has seldom been demonstrated in invertebrates. When recognition cues have been identified, they are usually found to be based on social status or family membership. Burying beetles rear a brood on an unpredictable resource and as […]

KAATZ, I.M.: Structurally divergent sound producing mechanisms in a clade of arioid catfishes function in different behavioral contexts Of the over 400 teleost fish families, 23% are known to have evolved two or more structurally and acoustically different sound producing mechanisms (SPMs). What is the functional significance of these independently derived SPMs? Structurally different SPMs […]

HOESE, W.J.*; MOONEY, R.; NOWICKI, S.: Neural Encoding of Multiple Song Types in the Swamp Sparrow HVc Many songbirds, including swamp sparrows (Melospiza georgiana), sing multiple song types as adults. In Songbirds that sing only a single song type, such as zebra finches and white-crowned sparrows, neurons in the song nucleus HVc are song-selective, firing […]

PERRY, G.*; GARLAND, T., JR.: Lizard home ranges revisited: traditional and phylogenetic perspectives Home range (HR) is the area traversed during food gathering, mating, and other routine activities. Thus, it is an ecologically important indicator of the behavioral and resource requirements of an animal. We reevaluated the factors affecting estimates of HR area in lizards. […]

WARKENTIN, K.M.: Hatching as a defense against egg predators: the role of vibrational cues Red-eyed treefrogs, Agalychnis callidryas, lay their eggs on vegetation overhanging water, into which the tadpoles fall at hatching. The age and developmental stage at which hatching occurs varies. The ability of hatchlings to escape from aquatic predators improves with development, and […]

Bee, M.A.*; Gerhardt, H.C.: Getting to Know You: Habituation as a Mechanism for Territorial Neighbor Recognition Territorial animals commonly exhibit low levels of aggression toward familiar neighbors in their usual territories and high levels of aggression toward strangers and neighbors in novel locations. Vocal recognition of neighbors is well known in songbirds, and also has […]

SPARKES, T.C.*; YAN, H.Y.; PRATER, C.; AKAMATSU, T: Condition-dependent acoustic signals and their importance for resolving aggressive conflicts in the skunk loach (Botia morleti): integrating sensory and behavioral approaches In the skunk loach, Botia morleti (Pisces, Cobitidae) sounds are produced during aggressive contests over access to hiding places. These contests are costly for both contestants […]
