Estimating the impact of whaling on global whale-watching [PDF]
Tourism Management, 2009 After the commercial whaling moratorium was enacted in 1986, whale-watching became one of the fastest growing tourism industries worldwide. As whaling was regarded as an activity that is incompatible with whale-watching, the possible resumption of commercial whaling caused an urgent need to investigate the potential negative effects of whaling on the ...

Early stages of tooth development in the harbor porpoise Phocoena phocoena
The Anatomical Record, EarlyView.Abstract Here we describe the stages of tooth development in toothed whales on the basis of the harbor porpoise (Phocoena phocoena). The aim of the study was to find out whether these stages are identical to those of other mammals analyzed so far although toothed whales are homodont and monophyodont.

Thermal Footprints of Whales [PDF]
Oceanography, 2009 Under the right meteorological conditions, whales can leave a trail of cool spots on the ocean surface that are detectable in infrared images. When the wind is light and the sun is shining, the surface water warms to produce a thermal gradient in the top
