Understanding genetic differentiation and speciation processes in marine species with high
dispersal capabilities is challenging. The Chilean dolphin, Cephalorhynchus eutropia, is the
only endemic cetacean of Chile and is found in two different coastal habitats: a northern
habitat with exposed coastlines, bays and estuaries from Valparaíso (33°02' S) to Chiloé...

The purpose of this essay is to explore the dynamics of social movements, and better understand why some populations succeed when others fail. This topic was motivated by travels across the United States and Europe. In these journeys, minority groups and their unequal treatment by society were a constant feature,...
Twentieth century commercial whaling drastically reduced the abundance of great whale populations in the Southern Ocean. Exploitation began on the south Atlantic island of South Georgia, where catch records account for over 175,000 whales killed. Modern whaling within the Southern Ocean depleted populations rapidly, and by 1966, hunting blue whales...
Through a desk-top analysis, this research shows that South African women have gained and utilize specialized skills, behaviors, and adaptations through their daily activities which are useful when applied to water resource management. Further, South African women are shown to build and draw on social capital as a way to...
The Antarctic blue whale (Balaenoptera musculus intermedia) was hunted to near extinction between 1904 and 1972, declining from an estimated initial abundance of more than 250,000 to fewer than 400. Here, we describe mtDNA control region diversity and geographic differentiation in the surviving population of the Antarctic blue whale, using...
An integrated analysis of turbulence observations from four unique instrument platforms obtained over
the Hawaiian Ridge leads to an assessment of the vertical, cross-ridge, and along-ridge structure of turbulence
dissipation rate and diffusivity. The diffusivity near the seafloor was, on average, 15 times that in the
midwater column. At 1000-m...
