Seasonal variation in thermal energetics of the Australian owlet-nightjar (Aegotheles cristatus).
Many birds living in regions with seasonal fluctuations in ambient temperatures (T(a)) typically respond to cold by increasing insulation and adjusting metabolic rate. Seasonal variation in thermal physiology has not been studied for the Caprimulgiformes, an order of birds that generally have basal metabolic rates (BMR) lower than predicted for their body mass. We measured the metabolic rate an...
متن کاملPhylogeny of the owlet-nightjars (Aves: Aegothelidae) based on mitochondrial DNA sequence.
The avian family Aegothelidae (Owlet-nightjars) comprises nine extant species and one extinct species, all of which are currently classified in a single genus, Aegotheles. Owlet-nightjars are secretive nocturnal birds of the South Pacific. They are relatively poorly studied and some species are known from only a few specimens. Furthermore, their confusing morphological variation has made it dif...
متن کاملSeasonal use of torpor by free-ranging Australian owlet-nightjars (Aegotheles cristatus).
With the exception of some data for common poorwills (Phalaenoptilus nuttallii) and anecdotal reports for a few other species, knowledge about the use of torpor by free-ranging birds is limited. Our study was designed to assess the use of torpor by free-ranging Australian owlet-nightjars (Aegotheles cristatus). We selected this species for study because of their relatively small body size (50 g...
متن کاملThe Karimui Trial of BeG
A preliminary report of the "blind" controlled trial of BCG in progress at Karimui in the Eastem Highlands of the Territory of Papua and New Guinea has been published (In). In March 1963, 85 per cent of the 5,000 persons comprising the Karimui population were tested with 0.1 ml. of 1: 1,000 OT (10 TU ). In March 1964, a sample of 1,331 persons was retested and the results of these hlberculin su...
متن کاملFirst observation of beamstrahlung.
Collisions of electron and positron bunches at the interaction point of the SLC (the linear collider at SLAC) h ave led to the first detected emission of beam-strahlung. This radiation, caused by the collective electromagnetic fields of one beam deflecting particles of the other, is a potential tool for optimizing collisions in linear colliders. With the advent of the linear collider1 as a tool...
