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 [...]

Los Herederos del Arca: Planeta Global

In this episode we will sum up the contents of the whole series with a brief forecast of what the immediate future might bring. The biggest problems analyzed will allow us to speculate with a tragic or a happy end, depending on each action taken by all of us today. The link between all of the protagonists, the ecosystems, the international societies and foundations, the people and the species, and the countries where we will travel during the series will let us see how fragile and complex is our world and how necessary it is to put local remedies to correct global problems; problems that after all could even end with our own species. Focusing on all those spectacular examples we have seen during the former five episodes we will see there is still some hope despite we are running out [...]

Hunters Conserve Wildlife: A Debate

Whether in the African bush or in America's game lands, hunting has bred enormous controversy in recent years. The killing of Cecil the lion in Zimbabwe in 2015 triggered a firestorm of international criticism over trophy hunting, and the regulated hunting of the white-tailed deer in the United States has sparked opposition over conservation and other issues. Defenders argue that hunting can conserve wildlife populations and raise money to protect animals. Opponents argue that hunting is an inhumane way to conserve wildlife and that the funds raised seldom benefit threatened animal populations or local communities. Is hunting appropriate? Do hunters conserve wildlife?
