In every alley of Ueno station, one of the main train stations in Tokyo, there were always groups of former war prisoners held in Siberia, still wearing their tattered uniforms and playing accordion, chanting, and panhandling. Many of them had lost their limbs and eyes and made a horrifying, yet curious, spectacle. As a little child, I could not help but ask my father “Who are they?” That was the beginning of a long dialogue about war between the two of us. That image has remained deep in my heart up to this day with the sorrowful sound of accordions. My father had just started work at an electrical laboratory at the University of Tokyo when he found he had been drafted into the imperial military and would be sent to China to work on electrical communications. He was 21 years old. His most trusted professor held a secret meeting in the basement of the university with the newest crop of drafted young men and told them, “Japan is engaging in an impossible war that we will never win.

    CONCEPTS & SYNTHESIS EMPHASIZING NEW IDEAS TO STIMULATE RESEARCH IN ECOLOGY Ecological Monographs, 81(3), 2011, pp. 349–405 Ó 2011 by the Ecological Society of America Regulation of animal size by eNPP, Bergmann’s rule, and related phenomena 1,3 2 MICHAEL A. HUSTON AND STEVE WOLVERTON 1Department of Biology, Texas State University, San Marcos, Texas 78666 USA 2University of North Texas, Department of Geography, Denton, Texas 76203-5017 USA Abstract. Bergmann’s rule, which proposes a heat-balance explanation for the observed latitudinal gradient of increasing animal body size with increasing latitude, has dominated the study of geographic patterns in animal size since it was first proposed in 1847. Several critical reviews have determined that as many as half of the species examined do not fit the predictions of Bergmann’s rule. We have proposed an alternative hypothesis for geographic variation in body size based on food availability, as regulated by the net primary production (NPP) of plants, specifically NPP during the growing season, or eNPP (ecologically and evolutionarily relevant NPP). Our hypothesis, ‘‘the eNPP rule,’’ is independent of latitude and predicts both spatial and temporal variation in body size, as well as in total population biomass, population growth rates, individual health, and life history traits of animals, including humans, wherever eNPP varies across appropriate scales of space or time. In the context of a revised interpretation of the global patterns of NPP and eNPP, we predict contrasting latitudinal correlations with body size in three distinct latitudinal zones. The eNPP rule explains body- size patterns that are consistent with Bergmann’s rule, as well as two distinct types of contradictions of Bergmann’s rule: the lack of latitudinal patterns within the tropics, and the decline in body size above approximately 608 latitude.

  • Chicago Wilderness Region Urban Forest Vulnerability Assessment
    United States Department of Agriculture CHICAGO WILDERNESS REGION URBAN FOREST VULNERABILITY ASSESSMENT AND SYNTHESIS: A Report from the Urban Forestry Climate Change Response Framework Chicago Wilderness Pilot Project Forest Service Northern Research Station General Technical Report NRS-168 April 2017 ABSTRACT The urban forest of the Chicago Wilderness region, a 7-million-acre area covering portions of Illinois, Indiana, Michigan, and Wisconsin, will face direct and indirect impacts from a changing climate over the 21st century. This assessment evaluates the vulnerability of urban trees and natural and developed landscapes within the Chicago Wilderness region to a range of future climates. We synthesized and summarized information on the contemporary landscape, provided information on past climate trends, and illustrated a range of projected future climates. We used this information to inform models of habitat suitability for trees native to the area. Projected shifts in plant hardiness and heat zones were used to understand how nonnative species and cultivars may tolerate future conditions. We also assessed the adaptability of planted and naturally occurring trees to stressors that may not be accounted for in habitat suitability models such as drought, flooding, wind damage, and air pollution. The summary of the contemporary landscape identifies major stressors currently threatening the urban forest of the Chicago Wilderness region. Major current threats to the region’s urban forest include invasive species, pests and disease, land-use change, development, and fragmentation. Observed trends in climate over the historical record from 1901 through 2011 show a temperature increase of 1 °F in the Chicago Wilderness region. Precipitation increased as well, especially during the summer.

  • Planetary Defence Activities Beyond NASA and ESA
    Planetary Defence Activities Beyond NASA and ESA Brent W. Barbee 1. Introduction The collision of a significant asteroid or comet with Earth represents a singular natural disaster for a myriad of reasons, including: its extraterrestrial origin; the fact that it is perhaps the only natural disaster that is preventable in many cases, given sufficient preparation and warning; its scope, which ranges from damaging a city to an extinction-level event; and the duality of asteroids and comets themselves---they are grave potential threats, but are also tantalising scientific clues to our ancient past and resources with which we may one day build a prosperous spacefaring future. Accordingly, the problems of developing the means to interact with asteroids and comets for purposes of defence, scientific study, exploration, and resource utilisation have grown in importance over the past several decades. Since the 1980s, more and more asteroids and comets (especially the former) have been discovered, radically changing our picture of the solar system. At the beginning of the year 1980, approximately 9,000 asteroids were known to exist. By the beginning of 2001, that number had risen to approximately 125,000 thanks to the Earth-based telescopic survey efforts of the era, particularly the emergence of modern automated telescopic search systems, pioneered by the Massachusetts Institute of Technology’s (MIT’s) LINEAR system in the mid-to-late 1990s.1 Today, in late 2019, about 840,000 asteroids have been discovered,2 with more and more being found every week, month, and year. Of those, approximately 21,400 are categorised as near-Earth asteroids (NEAs), 2,000 of which are categorised as Potentially Hazardous Asteroids (PHAs)3 and 2,749 of which are categorised as potentially accessible.4 The hazards posed to us by asteroids affect people everywhere around the world.
