Tropical forest soils are a significant source for N2O and NO. Current estimates of N2O and NO emissions areuncertain due to the limited number of fieldmeasurements and model input data. Furthermore, considerable spatialand temporal variability exists due to variation of soil properties, vegetation characteristics and meteorology.Weused a process-based model (ForestDNDC-tropica) to estimate N2O an

This paper examines the development of the role of a certain group of semi-officials, known as tongshi in Chinese, in Sino-Tibetan relations from the late-fourteenth century to the end of the eighteenth century, i.e. during the Ming and Qing dynasties, with particular reference to the part played by tongshi in events along the pre-modern Sino-Tibetan border. Tongshi were often Tibetans in Chinese

Compared to animals like ourselves, plants have a very flexible sexual life. Most plants are, for example, hermaphrodites with the potential capacity for reproduction by self-fertilization (or selfing). While selfing can provide several definite advantages for the individual plant, there is a downside; mainly the severe reduction in fitness due to inbreeding depression. To avoid the negative conse

Sustainability professionals are agents for change towards sustainable development. Such professionals require knowledge from a variety of disciplines, but also competencies to accomplish real-word change. This article evaluates an innovative course, Strategic Environmental Development, which immerses students in a real-life solution-oriented consultancy project in order to develop critical sustai

In this paper, we present a photoemission study of the interaction of Cu, Ag and Au with clean single-crystal Bi2CaSr2Cu2O8 superconductor surfaces. Both the valence-band and the Bi 5d, O 1s and Sr 3d core levels were monitored for all overlayers. Cu, Ag and Au were deposited as consecutively thicker layers starting with a third of a monolayer and progressing in steps up to a deposition in the ran

From an airstrip in Saudi Arabia, the CIA launches drones to 'legally' kill Al-Qaida leaders in Yemen. On the North Pole, Russia plants a flag on the seabed to extend legal claim over resources. In Brussels, the European Commission unveils its Emissions Trading System, extending environmental jurisdiction globally over foreign airlines. And at Frankfurt Airport, a father returning from holiday is

Urban theory has historically situated ethnic commercial strips as an organic extension of nearby ethnic residential enclaving. While this is still a useful way to frame such commercial spaces in many cities, this article argues that some areas of this sort function as a marketable branding mechanism (intended or not) to produce nearby residential gentrification. This article explores the influenc
