外来物种褐云玛瑙螺(非洲大蜗牛) 总被引:5,自引:0,他引:5
褐云玛瑙螺(Achatina fulica Ferussac,1822),又称非洲大蜗牛.原产于东非沿岸桑给巴尔、奔巴岛一带。据报道,现已知全世界玛瑙螺科Achatinidae共计有23属和亚属,其中玛瑙螺属Achatina有80种和亚种,在我国仅此1种.主要分布于我国福建南部、珠江三角洲、雷州半岛、海南岛、广西南部及云南南部等地区。这一外来物种给当地农业、园艺等经济作物造成很大的危害。 相似文献

A harmonious interspecies relationship is the key to the success of mixed afforestation. This study was conducted to assess the responses of afforestation species to their neighboring trees. We examined five types of stands—monocultures of Chinese pine (Pinus tabuliformis), black locust (Robinia pseudoacacia), sea‐buckthorn (Hippophae rhamnoides), and two mixtures (Chinese pine × black locust mixture and Chinese pine × sea‐buckthorn mixture)—in the Loess Plateau, northwestern China. The height and diameter at breast height of each tree species were measured, and rhizosphere soil, shoot, and root were sampled. In monocultures, black locust was taller than Chinese pine and sea‐buckthorn, while the height of Chinese pine and sea‐buckthorn was similar. In mixtures, Chinese pine grew better with sea‐buckthorn than alone as a result of modified soil properties and plant nutrition, but not with black locust. When Chinese pine was used as neighbors, it affected the level of arbuscular mycorrhizal (AM) colonization of black locust, soil properties and AM fungal spore density of black locust and sea‐buckthorn, but did not significantly affect their growth. Our results suggest that the reciprocal effects between tree species in mixture are not symmetric, and thus planning for efficient mixed afforestation requires knowledge of species‐specific growth rate, nutrient requirements, and species interactions. 相似文献

This paper studies the taxonomy of the genus Metolinus Cameron, 1920 (Coleoptera: Staphylinidae, Staphylininae, Xantholinini) from China and describes three new species: Metolinus xizangensissp. n. from Xizang (Tibet), Metolinus emarginatussp. n. fromSichuan, and Metolinus binariussp. n. from Yunnan. The Chinese fauna of the genus is thus increased to 8 species in total. A key to eight Chinese species is provided. Female genital segments and other important morphological characters are illustrated in line drawings for the new species as well as Metolinus shanicus Bordoni, 2002 and Metolinus gardneri (Cameron, 1945). The text also provides color plates with habitus photographs and a map to show the species' geographical distribution pattern. The type specimens of the new species are deposited in Institute of Zoology, the Chinese Academy of Sciences (IZ-CAS). 相似文献
