Epimedium species are traditional Chinese medicinal plants as well as potential groundcover and ornamental plants. In this study, genome size and genome structures of Epimedium species were investigated using flow cytometric and fluorescence in situ hybridization (FISH). The nuclear DNA content of Epimedium species ranged from 8.42 pg/2C (8230.7 Mbp) to 9.97 pg/2C (9752.8 Mbp). The pairwise nuc...

Zooplankton organisms with short generation times, such as rotifers, are ideal models to study general ecological and evolutionary questions on the population level, because meaningful experiments can often be completed within a couple of weeks. Yet biological analysis of such populations is often extremely time consuming, owing to abundance estimation by counting, measuring body size, or deter...

In an effort to resolve technical, operational, and cost problems associated wi th the existing approaches for measurement of water surface temperature, a program was initiated to develop and test a wholly airborne calibration of a thermal scanner system as an alternative. This technique involved development of a model relating the signal at the sensor to the surface temperature and the atmosph...

C of wetlands is often highly problematic due to the need to consider soil, plant, and Calcareous wetlands are of great interest in conservation biology. Previous research has suggested that there are significant differences hydrologic factors as fundamental components of these in soil microbial N cycle processes between calcareous wetlands develecosystems (Bridgham et al., 1996). The term wetl...
