Carbon sequestration in tropical secondary forests growing in all climates must be quantified to understand their potential role in adaptation and mitigation strategies of global climate change. Total aboveground biomass (TAGB), soil carbon, and total ecosystem carbon (TEC) were measured in 54 secondary forests growing along a broad bioclimatic gradient...
Tropical forest-to-agriculture conversions contribute to ~20% of contemporary global C emissions. Current global C flux estimates assume C is lost from vegetation and soils over time due to this conversion, and that C stocks in agricultural lands are fairly uniform across the tropics. Global C stock and flux estimates may...
The present highway funding system, especially fuel taxes, may become less reliable revenue sources in the future, while the transportation public agencies do not have the sufficient financial resources needed to meet the increasing traffic demand. Regarding the socio-economic impact of road privatization, a wide range of approaches and models...
The testimonios of three Canadian women athletes and the 1980 Olympic boycott are presented. The Latin American method of testimonio is adapted as a framework for understanding personal stories. Testimonios written in a series of interpretive narratives and poems--poetic testimonios--represent three women's voices. This study includes three journeys: the research...
In the past most research of family learning in informal science learning environments has included limited diversity among participants considering ethnic, cultural, and social economic status. The diversity seen in informal learning environments such as museums does not typically reflect that of the general population. Therefore, in order to foster...
