Prey escaping wolves, Canis lupus, despite close proximity Prey escaping wolves, Canis lupus, despite close proximity
We describe attacks by wolf (Canis lupus) packs in Minnesota on a white-tailed deer (Odocoileus virginianus) and a moose (Alces alces) in which wolves were within contact distance of the prey but in which the prey escaped.

Sex and age identification of palila Sex and age identification of palila
Methods to sex and age Palila (Loxioides bailleui), an endangered Hawaiian finch restricted to subalpine woodlands on Hawai'i, were identified on the basis of measurements and plumage characteristics of 17 museum specimens and 96 known-age, live Palila. Palila undergo a single annual molt during September-December following the breeding season. Presence of a complete or partial wingbar

Identifying sex and age of apapane and iiwi on Hawaii Identifying sex and age of apapane and iiwi on Hawaii
Methods to determine the sex and age of Apapane (Himatione sanguinea) and Iiwi (Vestiaria coccinea) were developed on the basis of 189 museum specimens and 91 live birds captured in mist nets on the Island of Hawaii (USA). Both species retain all juvenal primaries and some juvenal secondaries and body feathers after the first prebasic molt and attain full adult plumage after the second...

'Tool' use by the red-tailed hawk (Buteo jamaicensis) 'Tool' use by the red-tailed hawk (Buteo jamaicensis)
Perhaps the best documented example of regular tool use for a falconiform is the Egyptian Vulture (Neophron percnopterus) striking an Ostrich (Struthio camelus) egg with a stone (J. van Lawick-Goodall and H. van Lawick-Goodall 1966, Nature 212:1468-1469; R.K. Brooke 1979, Ostrich 50:257-258). Another species, the Lammergeier (Gypaetus barbatus), routinely drops bones on stone slabs to...

Site tenacity of the endangered palila Site tenacity of the endangered palila
Strong site tenacity might prevent Palila (Loxioides bailleui), an endangered Hawaiian honeycreeper, from repopulating favorable habitats in their former range. We used radio telemetry during the nonbreeding and breeding seasons to study movements and dispersal rates of 57 Palila. All Palila remained in the study area, and home range sizes and movement distances were small relative to...

A receptor binding assay applied to monitoring the neurotoxicity of parathion to Peromyscus after oral exposure A receptor binding assay applied to monitoring the neurotoxicity of parathion to Peromyscus after oral exposure
Many naturally occurring toxins, as well as pesticides, metals, and other compounds that occur in our environment from anthropogenic activities, stimulate or antagonize neuro-receptors to produce acute and/or chronic toxicities. Recent advances in laboratory instrumentation and the availability of a variety of radiolabeled ligands and type-specific drugs for numerous receptors make it...

Benthic Acoustic Stress Sensor (BASS): Electronics Check-Out Procedures Benthic Acoustic Stress Sensor (BASS): Electronics Check-Out Procedures
Summary The procedures described here are presented so that a technician with limited experience with BASS can perform basic tests which, when executed properly, should be a thorough evaluation of the health of the system. This is not intended as an in depth explanation of how BASS works. Should any significant problems be found, it is suggested that you contact the manufacturer...

Seismic survey of Lake Baikal, Siberia cruise report: RV Balkhash 25 August to 25 September 1992 Seismic survey of Lake Baikal, Siberia cruise report: RV Balkhash 25 August to 25 September 1992
Introduction A comprehensive multichannel seismic-reflection (MCS) and ocean bottom seismometer (OBS) seismic-refraction survey of Lake Baikal, Siberia was undertaken during August-September 1992 as a collaborative research project by U.S. and Russian scientists. This project was supported by funding from the U.S. Geological Survey, the U.S. National Science Foundation and the Russian...
