A model of magnetoreception proposes that the avian magnetic compass is based on a radical pair mechanism, with photon absorption leading to the formation of radical pairs. Analyzing the predicted light dependency by testing migratory birds under monochromatic lights, we found that the responses of birds change with increasing intensity. The analysis of the orientation of European robins under ...

Impression materials used in the analysis of bite marks are required to maintain their stability and integrity for extended periods. It has been observed that certain impressions taken of skin lose their properties with time, becoming sticky and unusable as evidence. The objective of this study was to investigate the onset of "stickiness" in two commonly used dental impression materials when br...

Aktmct-A new variety of impact giass has been discovered at Zhamansbin impact crater (U.S.S.R.). The crater has been known as the source of different impact glasses such as irghizites and Si-rich zhamanshinites @-rich varieties) and Si-poor (andesitic) zhamanshinites. The newly discovered impact glass is ofdistinct blue color and shows a layered structure with numerous small vesicles. The blue ...

As demand on freshwater resources increases, managers are increasingly tasked with identifying water withdrawal, storage, and management strategies that minimize impacts on aquatic species. Identifying critical features of the flow regime that sustain particular ecological processes can be difficult due to site and speciesspecific characteristics. Our goal was to simulate tradeoffs between diff...

The following case report describes a 1-year-old female cheetah (Acinonyx jubatus) with bilateral blindness and unresponsive pupils. For comparison, a second healthy 2.5-year-old male cheetah without visual deficits was also examined. Clinical examination of both animals included biomicroscopy, indirect ophthalmoscopy, tonometry, and electroretinography. The young female cheetah showed no menac...
