Antoine Joseph Jean Solier, a French naturalist, described 53 species of Staphylinidae of the Chilean fauna, among them three species in a new genus Mecorhopalus (M. ater, M. bipustulatus and M. elongatus). Today these species are regarded as Aleochara atra, A. solieri and A. mutare , respectively. The objective of this study is to provide an updated description and nomenclatural status of thes...

(IMO-H) was examined in vitro and in vivo experiments. IMO-H could not be used as a substrate for the crude glucosyltransferases (GTases) of Streptococcus sohrinus 6715 to synthesize "'ater-insoluble glucan. Moreove]', it not only significantly inhibited the synthesis of water-insoluble glu¢ an from sucrose, but also the sucrose-dependent adherence of these growing celJs the glass surfaces. In ...

Many birds perform visual signals during their learned songs, but little is known about the interrelationship between visual and vocal displays. We show here that male brown-headed cowbirds (Molothrus ater) synchronize the most elaborate wing movements of their display with atypically long silent periods in their song, potentially avoiding adverse biomechanical effects on sound production. Furt...

Brood parasites provide a particularly good opportunity for the study of host-parasite evolution because they directly affect the reproductive success of their hosts. Two parasitic species, the common cuckoo (Cuculus canorus) and the brown-headed cowbird (Molothrus ater), differ widely in their relationships with their hosts, yet share the attribute of having been particularly well studied by b...

ater suppliers need information about the removal efficiency of Cryptosporidium and potential surrogate parameters over a broad range of water quality and treatment conditions. These data can be obtained by tracking environmental concentrations of Cryptosporidium through full-scale treatment plants or feeding larger numbers of oocysts through pilot-scale facilities. Table 1 shows published Cryp...

Five variables were studied relating to the emergence of sociality in hand-reared cowbirds (Molothrus ater): proximity, sex assortment, reactions to adults, head-down displays, and vocalizations. The authors were especially interested in female sociality because adult female birds influence male courtship, song content, and use through proximity, attention, and displays. The authors found that ...
