Mosaic landscapes under shifting cultivation, with their dynamic mix of managed and natural land covers, often fall through the cracks in remote sensing-based land cover and land use classifications, as these are unable to adequately capture such landscapes' dynamic nature and complex spectral and spatial signatures. But information about such landscapes is urgently needed to improve the outcom...
Fixed-bed reactors have gained growing attention for the cultivation of mammalian cells. They allow for a low shear stress cultivation of adherent and non-adherent cells due to the immobilization of cells within macroporous carriers. Their potential has been demonstrated for many cell culture purposes. Some of the recent developments are presented in this review, including improved antibody pro...
The Piedmont region in the United States has been eroded and gullied due to deforestation and cultivation during the 1700 and 1800. Currently, a majority of these gullies are under forest vegetation and appear stable; however, neither the hydrology of these gullies, nor their sediment contribution to surface waters, has been quantified. This study instrumented eight gullies ranging in size from...
Deep-sea hypersaline anoxic lakes (DHALs) of the Eastern Mediterranean represent some of the most hostile environments on our planet. We investigated microbial life in the recently discovered Lake Medee, the largest DHAL found to-date. Medee has two unique features: a complex geobiochemical stratification and an absence of chemolithoautotrophic Epsilonproteobacteria, which usually play the prim...
Clarke, R.C. 1995. Hemp (Cannabis sativa L.) Cultivation in the Tai'an District of Shandong Province, Peoples Republic of China. Journal of the International Hemp Association 2(2): 57, 60-65. This paper summarizes the history of hemp (Cannabis sativa L.) cultivation and traditional use in the Tai'an District of Shandong Province in the People's Republic of China, and investigates the cultivatio...
The historical paradigm of the deep ocean as a biological 'desert' has shifted to one of a 'rainforest' owing to the isolation of many novel microbes and their associated bioactive compounds. Recently, there has been an explosion of information about novel bioactive compounds that have been isolated from marine microbes in an effort to further explore the relatively untapped marine microbes and...
Ipomoea (morning glory) is the largest genus in the family Convolvulaceae. Cultivation of morning glory plants began in the late Edo period in Japan, and this horticultural success resulted in thousands of plants with varying floral displays. In addition to the different flower morphologies, leaf shape is highly variable within this family making it an ideal group in which to study leaf develop...
