DYER, Fred C.: Vector Navigation in Insects Honey bees and other insects that forage from a central place face a formidable navigational problem, which is to find their way repeatedly between their nest and feeding places in the environment. A key component of the insects’ solution to this problem is an ability to determine the […]

DITTMAN, A.H.: Sensory systems and neural mechanisms involved in salmon homing Pacific salmon (Oncorhynchus spp.) are well known for their long distance homing migrations from oceanic feeding grounds back to their river of origin to spawn. During these migrations, salmon travel through a variety of habitats (e.g., oceans, estuaries, lakes, rivers) and therefore may utilize […]

WILLIS, M.A.: Odor-modulated navigation in flying insects Many organisms, ranging from bacteria, through nematodes, to insects, fish and mammals, use air- or water-borne plumes of odor molecules to locate distant unseen resources. Remarkably, the movement tracks that many species produce when tracking odors have a very similar side-to-side zigzag shape. While this similarity does not […]

WALCOTT, C: Multimodal Orientation and Navigation in Homing Pigeons How homing pigeons displaced into unfamiliar territory find their way home has been the subject of extensive experimentation and debate. One reason for the controversy is that pigeons seem to use multiple cues. Clock-shifting experiments show that experienced pigeons use the sun as a preferred compass; […]

BEASON, R. C.: Mechanisms of Magnetic Orientation in Birds The ability of birds to navigate long distances during migration and to return home following displacement involves use of the Earth�s magnetic field for many if not all species. Behavioral and physiological studies support the existence of a magnetic compass in birds and the possibility of […]

LOHMANN, K.J.: Magnetic Orientation and Navigation in Marine Animals The Earth�s magnetic field provides a pervasive source of directional information used by diverse marine animals. Behavioral experiments with sea turtles, spiny lobsters, and the mollusc Tritonia have revealed that all have a magnetic compass sense, despite vast differences in the environment each inhabits and the […]

STRAUSFELD, NJ: INSECT MUSHROOM BODIES: DO THEY PLAY A ROLE IN PLACE MEMORY? Studies of cockroaches have shown that bilateral lesions of the mushroom pedunculus results in the abolish of place memory, as defined by the insects ability to use distant cues for learning and recalling the location of a target that is itself not […]

ZIMMER, R.K.*; ZIMMER, C.A.: Chemical Information Flow in Aquatic and Terrestrial Environments Understanding the mechanisms by which environmental chemical signals mediate various life-history processes can lead to important insights about the ecology and evolution of organisms. For chemical signals released into the environment, establishing the principles that control chemical production and transport is critical for […]

BINGMAN, V.P.*; SIEGEL, J.J.; HOUGH III, G.E.; KAHN, M.C.: Adaptive Variation in the Hippocampal Representation of Environmental Space Behavioral, anatomical and neurochemical data demonstrate that the hippocampus of birds and mammals are homologous structures playing a critical role in the memory representation of environmental space used for navigation. Uncertain at the electrophysiological level is whether […]

NELSON, M.E.: Active Electrosensory Signal Acquisition in Weakly Electric Fish Animals can actively influence the content and quality of sensory information that they acquire from the environment by motor control of peripheral sensory surfaces. Black ghost knifefish (Apteronotus albifrons) are nocturnal hunters that feed on insect larvae and small crustaceans in the freshwater rivers of […]
