13. “Spshing Noise”: Biological Significance of Its Attraction and Nonattraction by Birds
Many New World passerine birds, especially migrants which join mixed flocks of local species in the Neotropics, are attracted to a noise termed “spshing” used by humans to attract birds into view. The noise is effective because it mimics the vocalizations of certain bird species which play a central bonding role in mixed species flocks. Migrants join the

14. Assembly of avian mixed-species flocks in Amazonia.
Diamond's "assembly rules" model posits that competitive interactions among species govern the composition of avifaunas. Although originally applied to islands in archipelagoes, this controversial set of hypotheses is difficult to test because islands differ in habitat and resource availability, colonization history, and stochastic effects. Permanent mixed-s

15. Detection of Salmonellae in Chicken Feces by a Combination of Tetrathionate Broth Enrichment, Capillary PCR, and Capillary Gel Electrophoresis
This report describes a rapid detection procedure for salmonellae from chicken feces by the combination of tetrathionate primary enrichment (preenrichment [PE])-bacterial lysis-capillary PCR and capillary gel electrophoresis. Pure Salmonella enterica serovar Enteritidis 64K was reisolated and detected by capillary PCR after buffered peptone water and nutrien
