In summary, available data on the natural history of dragonfly
migrations suggest that: (1) large migratory flights precede the seasonal decline of aerial insect populations; (2) coastlines and other linear topographic features elicit a behavioral response from migrants (specifically, a change in flight direction), resulting in the concentration of migrants along such leading lines; (3) cold fronts may serve as proximate cues for migration; (4) northwesterly winds associated with cold fronts may result in passive wind drift, which will magnify the concentrating effect of leading lines; and (5) reorientation of swarm migrations in water-crossing situations may reflect social facilitation of risk-averse behavior.
discovery provides high speed, non-contact dispensing from a disposable, positive displacement tip, which will effectively enable researchers to reduce assay development time as well as improve assay robustness in HTS.
