The results showed that malic enzyme exists in heart, gonads, eyes and gills tissues in both female and male V. macrolepis. There was only one ME-2 in heart and ME-1 in eye of female fish, while there were ME-1 and ME-2 in heart and ME-2 in eyes of male fish. Ovary contained ME-1 and ME-2, while spermary only contained ME-1. In kidney and spleen tissues, malic enzyme was found only in female fish, while in muscle, malic enzyme existed only in male fish. The phenotypic of malic enzyme had obvious differences no matter in the same organ of different sexes in V. macrolepis or different organs in the same sex. But there were no differences among different individuals of the same sex. The results will provide basic data for developmental genetics, breed improvement and directed breeding of V. macrolepis, and lay a foundation for its development and protection.展开更多
Spatio-temporal relationship of the phytophagons Clania miniscula (Butler) and garden spiders was examined through analysis of their niche and distribution as they occur in sasanqua orchard in Southern Anhui, China ...Spatio-temporal relationship of the phytophagons Clania miniscula (Butler) and garden spiders was examined through analysis of their niche and distribution as they occur in sasanqua orchard in Southern Anhui, China from June 2003 to May 2004. The dynamic relationships between Clania minuscula and garden spiders were seasonal in time and space. Spatio-temporal niche breadth was high for the two groups, ranging from 0.57 to 0.98; niche overlap was also high between the two groups from 0.76 to 0.96 during the seasons of June 2003 to May 2004. Geostatistical results indicated that Clania minuscula and garden spiders were aggregated during the emergence periods. The pest Clania minuscula was spatially dependent to a range from 33.48 to 46.84 m while spatial dependence from 30.93 to 51.11 m for garden spiders. The correlation analysis of distribution maps further illustrate the distribution of garden spiders always coincided with that of Clania minuscula. These results showed spatio-temporal synchrony of Clania minuscula and garden spiders at different periods. Adequate knowledge of spatio-temporal correlation between Clania minuscula and garden spiders contributed to provide information for biocontrol at different periods in sasanqua orchard.展开更多
