Sky Compass Orientation in Desert Locusts—Evidence from Field and Laboratory Studies
Locusts are long-range migratory insects. At high population density, immature animals form marching hopper bands while adults take off and form huge swarms of millions of animals. At low population densities animals are solitarious, but likewise migrate, mostly during the night. Numerous studies aimed at predicting locust infestations showed that migrations both as hopper bands and as adults a...
متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
Desert ants do not rely on sky compass information for the perception of inclined path segments.
On their foraging excursions, desert ants (Cataglyphis fortis) navigate by means of path integration, exhibiting high precision even in undulating terrain. To avoid errors in their home vector the ants must measure the slopes of ascents and descents in their itinerary. This information is necessary to convert the distances actually walked on the slopes into the ground distance, which is the cru...
متن کاملNavigation and Compass Orientation by Insects According to the Polarization Pattern of the Sky
A recent theory attempts to explain how bees take their compass orientation from the pattern of polarized light in the sky (S. Rossel and R. Wehner, Nature 323, 128-131 (1986)). According to this theory, orientation can be erroneous and lead to the wrong course of a recruited bee in search of the foraging site whenever only a small patch of the blue sky is visible to the bee. It is shown that o...
متن کاملBridging Laboratory and Field Studies
The method we present here retrospective review and rating of Field Operational Test (FOT) data is designed to capture both the rigor of the laboratory and the ecological validity of the field. It is tailored for studies of driver acceptance of active safety systems. The method makes it possible to leverage expensive FOT data within the confines of the laboratory.
