DAVIS, E. C.; University of Kansas, Lawrence: Odor tracking to a food source by the pulmonate gastropod Meridolum gulosum (Gould, 1864) from New South Wales, Australia Environmental cues provide information that helps animals find nearby food sources. Some gastropods are able to find food sources by following airborne chemical plumes using both tropotaxis and anemotaxis. […]

WASSMER, G.T.; BIXLER, J; FULLER, C.A.; HOBAN-HIGGINS, T.M.; Bloomsburg University of Pennsylvania; Bloomsburg University of Pennsylvania; Univ. of California, Davis; Univ. of California, Davis: Observations of the effects of light and gravity on biological rhythms in the desert beetle Cryptoglossa verrucosus Biological rhythms are daily fluctuations in physiology and behavior that are regulated by an […]

WOLF, B.O; MCKECHNIE, A.E.; Univ. of New Mexico, Albuquerque; Univ. of New Mexico, Albuquerque: Nutrient Dynamics in a Desert Bird Community; the Functional Importance of Columnar Cacti Columnar cacti are prominent features of arid and semi-arid ecosystems in the Neotropics. Cacti are unusual in that they offer an abundance of succulent, energy rich fruit to […]

TRITES, AW; HUNT, KE*; WYNNE, K; WASSER, SK; Univ. British Columbia; Univ. Washington; Univ. Alaska; Univ. of Washington: Noninvasive assessment of possible nutritional stress in Steller sea lions (Eumetopias jubatus) using fecal glucocorticoid and dietary analyses The western population of the Steller sea lion (Eumetopias jubatus) experienced a pronounced population decline in the 1970’s-90’s. The […]

SHOUKFEH, Omar M.; AHMED, Nafisa; CARR, James A.; Texas Tech Univ., Lubbock; Texas Tech Univ., Lubbock; Texas Tech Univ., Lubbock: Neurochemical Coding of a Behavioral Circuit Breaker The Texas toad Bufo speciosus responds to a moving but otherwise artificial prey-item (worm) by orienting toward the worm in precisely the same manner that it would approach […]

SANE, S.P.; DIEUDONNE, A.; Univ. Of Washington, Seattle; Univ. Of Washington, Seattle: Neuroanatomy of antennal bristle fields in the hawk moth, Manduca sexta Insect antennae are multi-sensory organs capable of detecting odor, humidity and temperature. Antennae also serve an important mechanosensory function via neurons that encode motion of their basal scape-pedicel joint. Across diverse insect […]

MEEHAN, T.D.; LEASE, H.M.*; WOLF, B.O.; Univ. of New Mexico; Univ. of New Mexico; Univ. of New Mexico: Negative Indirect Effects of Insectivores (Cliff Swallows) on the Fruit Set of an Insect-Pollinated Herb (Sweet Clover) Though an abundance of research has focused on direct interactions between birds and plants, relatively few studies have reported on […]

Because of their wide nesting distribution along the eastern seaboard of […]

GUNNELS, Charles/W; Univ. of Florida: Morphometric and energetic differences between the alternative reproductive strategies of female Mischocyttarus mexicanus (Hymenoptera: Vespidae) Alternative strategies demand examination. This type variation seems to contradict a general expectation of evolutionary biology, which predicts a single, optimal strategy should be fixed within a population in most circumstances. Female Mischocyttarus mexicanus (Hymenoptera: […]
