Vancomycin-Resistant Enterococci, Point Barrow, Alaska, USA

To the Editor: An increasing number of bacterial infections are now diffi cult or impossible to treat (1) because of the misuse of antimicro-bial drugs and the epidemic spread of bacterial resistance to these drugs (2). The most alarming reports are of me-thicillin-resistant Staphylococcus au-reus, extended-spectrum β-lactamase producers, and vancomycin-resistant enterococci (VRE). Although kno...

Masked tonal hearing thresholds in the beluga whale.

Masked tonal thresholds were measured for a beluga whale at one noise level and 32 frequencies between 40 Hz and 115 kHz. Critical ratios were estimated and compared with those previously measured for the bottlenose dolphin. Beluga whale critical ratios were found to be about 3 dB lower than those of the bottlenose dolphin. Absolute tonal thresholds were extended below previous measurements to ...

Sperm whale dive behavior characteristics derived from intermediate‐duration archival tag data

Here, we describe the diving behavior of sperm whales (Physeter macrocephalus) using the Advanced Dive Behavior (ADB) tag, which records depth data at 1-Hz resolution and GPS-quality locations for over 1 month, before releasing from the whale for recovery. A total of 27 ADB tags were deployed on sperm whales in the central Gulf of California, Mexico, during spring 2007 and 2008, of which 10 wer...
