Guam’s indigenous people have endured centuries of hostilities

HAGATNA, Guam — The threatened missile attack by North Korea on Guam has prompted calls for peace from the island’s indigenous people, who are weary of yet another conflict after enduring centuries of hostilities.

About one-third of the U.S. territory’s 160,000 people identify as Chamorro, the indigenous group that is believed to have migrated to Guam from Indonesia and the Philippines an estimated 3,500 to 4,000 years ago. It is believed to be one of the world’s first seaward migrations.

“Us guys, we bust our butts. It’s dangerous work doing what we do, but I love it out here. There’s nothing like it.” So stated Tony Gale, a veteran logger from rural New York, in an interview with Huffington Post. The digital media company recently published a comprehensive piece on the intersection between suburban development and rural communities, and Gale is representative of many in America’s rural workforce who are challenged by the changing dynamics brought about by urban sprawl.

Despite the global trend in urbanization, little is known about patterns of biodiversity or provisioning of ecosystem services in urban areas. Bee communities and the pollination services they provide are important in cities, both for small-scale urban agriculture and native gardens. To better understand this important ecological issue, we examined bee communities, their response to novel floral resources, and their potential to provide pollination services in 25 neighborhoods across Chicago, IL (USA).

Despite improvements in the use of soil conservation practices, crop rotation and managed fertilizer applications, large losses of nitrogen (N) in runoff continue to occur from row-cropped watersheds. Increasing requirements for implementing water quality standards in the United States, has increased pressure for the development of research-based guidelines to reduce N losses from agricultural runoff.

United States policy makers are promoting bio-fuels as an economic development opportunity, especially for rural America. A USDA study claims that developments in energy production from biomass could increase profits for agricultural commodity producers. However, as William Heffernan and his colleagues have demonstrated, concentration in the agrifood sector limits the economic benefits going to the commodity producers.

We develop a new partial equilibrium, four-region world trade model for the soybean complex comprising soybeans, soybean oil, and soybean meal. In the model, some consumers view genetically modified Roundup Ready (RR) soybeans and products as weakly inferior to conventional ones; the RR seed is patented and sold worldwide by a U.S. firm; and producers employ a costly segregation technology to separate conventional and biotech products in the supply chain.

This paper argues that law and economics has not come to grips with Arrow's limitation on social welfare economics nor with the evolutionary character of economic and legal institutions. Arrow's theorem makes the concept of a socially efficient economic institution dependent on a prior allocation of property rights. A socially efficient result is efficient only within the bounds of the initial allocation of property rights. A differing initial

Rare species of plants are especially vulnerable to extinction when populations are few, have small numbers of individuals, and are fragmented. Such conditions lead to a reduction in gene flow and genetic diversity, and encourage inbreeding depression. We conducted a study of the reproductive biology and population genetics of Penstemon debilis (Plantaginaceae), a Federally Threatened species endemic to a small region of oil shale extraction in western Colorado, USA. Most of the habitat area is privately owned and undergoing natural gas extraction activities.

AIM: The geographical expansion of white‐winged doves (Zenaida asiatica) in North America has attracted the attention of biologists and sportsmen because of their recreational and aesthetic value; however, data on factors driving the spatial spread of this species are lacking. We examined spatial and temporal patterns of range expansion for white‐winged doves along the northern edge of their geographical range from 1979 to 2007 and used a dynamic occupancy model to estimate when and where doves would be found along an expansion gradient. LOCATION: Southern half of the USA.
