Echolocation by the harbour porpoise: life in coastal waters
The harbor porpoise is one of the smallest and most widely spread of all toothed whales. They are found abundantly in coastal waters all around the northern hemisphere. They are among the 11 species known to use high frequency sonar of relative narrow bandwidth. Their narrow biosonar beam helps isolate echoes from prey among those from unwanted items and noise. Obtaining echoes from small objec...
متن کاملModels with a porpoise.
F ontaine et al. provide insight into the structure of a geographically disjunct population on a severe downtrend (1). To understand these data, they turned to a Bayesian statistical approach, providing the mathematical base for changing existing beliefs in light of new evidence. Their hybrid simulation/genomic analysis is one of the latest demonstrations that increasing crossfertilization betw...

in their length can quantitatively explain the dynamic range of all helical and non-helical cell geometries. The purified, detergent insoluble cytoskeleton complex from spiroplasmas contains over ten proteins, the main one being a 59 kDa product of the fib gene with no known prokaryotic or eukaryotic homologs. Infectivity in spiroplasmas is governed by an unusual lipoprotein, spiralin, which co...
متن کاملEcholocation range of captive and free-ranging baiji (Lipotes vexillifer), finless porpoise (Neophocaena phocaenoides), and bottlenose dolphin (Tursiops truncatus).
The interclick intervals of captive dolphins are known to be longer than the two-way transit time between the dolphin and a target. In the present study, the interclick intervals of free-ranging baiji, finless porpoises, and bottlenose dolphins in the wild and in captivity were compared. The click intervals in open waters ranged up to 100-200 ms, whereas the click intervals in captivity were in...
متن کاملBartonella henselae in Porpoise Blood
We report detection of Bartonella henselae DNA in blood samples from 2 harbor porpoises (Phocoena phocoena). By using real-time polymerase chain reaction, we directly amplified Bartonella species DNA from blood of a harbor porpoise stranded along the northern North Carolina coast and from a pre-enrichment blood culture from a second harbor porpoise. The second porpoise was captured out of habit...
