Cloning and Conservation [electronic resource]

On January 8, 2001, on the outskirts of Sioux Center, Iowa, the first successful clone of an endangered species was delivered by cesarean section from an ordinary cow named Bessie. Noah, the new-born gaur (a species of wild ox native to India) was created by fusing cryogenically preserved skin cells from a zoo gaur with a cow egg emptied of its DNA. The entire procedure was done without ever coming into contact with a living gaur. This science bulletin asks the important question, "Can technology help save endangered species?

Species and Sprawl [electronic resource]: A Road Runs Through It

As urban and suburban sprawl continue to spread across the country, road mortality has been found to be a major factor in the decline of turtle populations throughout the Northeast. This science bulletin visits the University of Massachusetts in Amherst, where, in the hopes of informing future development, researchers are radio-tracking wood turtles to better quantify their movement patterns and habitat needs.

Lemurs in Madagascar [electronic resource]: Surviving on an Island of Change

On the world's fourth-largest island, and virtually nowhere else, lives an entire "infraorder" of primates: the three dozen or so lemur species. But Madagascar has radically transformed since another primate - humans - arrived 2,000 years ago. Rampant deforestation, habitat fragmentation, and other anthropogenic factors are impacting lemurs much faster than evolution can mitigate the effects. This science bulletin follows American and Malagasy scientists through the country's remaining forests to learn how these compelling creatures are coping with change.

Wild at Heart [electronic resource]: The Plight of Elephants in Thailand

Elephants in Thailand have traditionally been captured in the wild and trained to work in the logging industry. However, with Thailand's ban on logging in 1989, elephants and their keepers lost a crucial source of employment and means of survival. In addition, loss of habitat is further challenging the survival of elephants. This science bulleting travels to northern Thailand to take a look at a project that may be able to help: an experiment in which elephants are returned to the forest to see whether they can form new family groups and survive on their own in the wild.

Acid Oceans [electronic resource]

If you're an ocean creature with a hard shell - like a sea urchin, a hermit crab, or a coral polyp - you prefer ocean water with a pH of about 8.2. This chemistry makes it easy to assemble your armor from carbon-based building blocks dissolved in the ocean. Since the beginning of the industrial age, though, the ocean has been absorbing the greenhouse gas carbon dioxide from the air. The increase in carbon dioxide has made the ocean's pH more acidic, dropping to 8.05 on average. Biologists like Gretchen Hofmann are realizing that this tiny change is hampering the development of hard-shelled marine creatures, leaving them more vulnerable to environmental stressors. This science bulletin joins Hofmann's team as they use a an acidic ocean environment in a lab at the University of Califor [...]

Last Journey for the Leatherback? [electronic resource]

Only a few hatchlings in a leatherback turtle brood are destined to make it to adulthood-and although a mature specimen's large size and oily flesh tend to ward off most predators, the majestic marine reptile still faces a wide range of human dangers. Chemical and solid waste pollutants create serious hazards, but the greatest harm comes when leatherbacks are snared as bycatch-a frequent occurrence due to the ineffectiveness of many excluder devices. This program provides an introduction to the world of the leatherback turtle and outlines the threat that industrial fishing poses to the species' survival.
