This article describes the ways in which the Nuri Talaud, a small colorful bird located on an island at the northern reaches of Indonesia, first became a hunted commodity and evolved into a thriving protected species. Told from the life history of Om Zaka, a local hunter turned bird conservationist, this article describes the background that shaped the shifting values placed on the Nuri Talaud. The bird initially gained value as a symbol of the state through its selection for inclusion in Indonesia’s national theme park. As a result of its newfound prominence, local hunters emerged to systematically hunt the bird for sale through a network of international species trade. Nearly facing extinction, various actors and initiatives came together to protect the Nuri Talaud. This paper shows the ways in which a species can be targeted to almost extinction, and the processes that can take shape to ensure its protection.

Although theories of the evolution of senescence differ in the mode of action by which genes are thought to control the aging process, they all view the rate of senescence as an adaptable feature of life history and therefore modifiable by natural selection. Tests of theory, however, have generally yielded mixed results. The life-span of Drosophila melanogaster increased strongly in populations selected for late reproduction in these experiments. Delayed senescence was accompanied by a reduced early fecundity, suggesting pleiotropic genetic control of the aging process. Reproduced by permission. Leo S. Luckinbill, Robert Arking, Michael J.
