Whales in Fjords: Two Case Studies

Killers, Humpbacks, Blues, and Rocks. The world's fjords harbor some of the most unique and wondrous populations of cetaceans, spectacles matched only by the steep-walled landscapes in which they are found. Here the presenter explores the ecology, acoustics, and conservation of fjord-land whales via two case studies: the whale community of northern British Columbia and the blue whales of Chilean Patagonia.

17,506 Islands: An Indonesia Picture Show
The nation of Indonesia encompasses the largest archipelago on earth. It is a colorful constellation of the world's most volatile, dangerous, diverse, and breathtaking landscapes, monsters, and peoples. It is the birthplace of "biogeography". It was the muse for the theory of evolution. Its phenomena are the stuff of myth, daydream, and jungle fever: Krakatoa. The Orangutan. Komodo Dragons. Caves. The Birds of Paradise. Borneo. Tigers. Pangolins. Manta Rays. River dolphins. Tarsiers. Aboriginal whaling societies. BEETLES. Rhinos. Elephants. The giant, stinky Rafflesia flower. The corals.

Whales of the Mediterranean
Cetaceans and the Mediterranean Sea go way, way back. These salty, mythological waters are what remain of the great Tethys Sea, the ancestral birthplace of whales and dolphins. Today, the Med's whales -- or what remain of them -- are being pressured from all sides by burgeoning civilizations. Here we briefly consider the diversity and grandeur of the 13 species found within this sea, through the eyes of one of the most prolific research institutions in the region: the Tethys Research Institute.

This presentation is an exact video transcript of Eric's talk to the Sewanee Natural History Society in November 2009. [It does not officially represent the views or opinions of the Tethys Research Institute]
