生态学中关键种的研究综述   总被引:1,自引:0,他引:1  
关键种 (Keyspecies)是生态学研究 ,特别是生物保护学研究中的一个研究热点。关键种可以是为了最大程度地保护生物多样性而进行优先保护的目标。但是目前的研究来看 ,在群落或者生态系统中确定关键种不是一件容易的事情。本文通过对有关关键种研究的回顾 ,探讨了国内外的研究状况 ,着重说明了关键种在实际研究中的实践以及存在的局限性 ,并且重点阐述了确定关键种的一些实验方法和定量测度方法 ,并进行了简要的评述。  相似文献

We have classified 11 species recently recognized as belonging to the genus Elymus into a resurrected and legitimate genus Campeiostachys Drobov according to the International Code of Botanical Nomenclature. Our action is based on the rationale of monophyly, discrimination, and practicality discussed in detail. Currently Elymus contains a vast number of species with different genomes which often, but not always, can be differentiated by cytological and molecular features, but are difficult to separate by tr...  相似文献

Pollen grains of 15 taxa of the genus Chelonopsis (14 spp. and 1 variety) from China and Japan and 6 species of the closely related genera Bostrychanthera (1 species) and Gomphostemma (5 species) were examined by light and scanning electron microscopy. Of these, the pollen morphology of 18 taxa was studied for the first time. Pollen grains were found to be tricolpate with polar lengths of 20.8–30.0 μm and equatorial widths of 17.5–27.3 μm. The basic shape of the pollen in most taxa is subprolate or prolate-spheroidal, but spheroidal, subprolate-spheroidal, oblate-spheroidal, and prolate-subprolate grains are also found in some species. The surface is generally reticulate or suprareticulate in Chelonopsis and granulate in Bostrychanthera. In comparison with those of Chelonopsis and Bostrychanthera, the pollen grain surfaces of Gomphostemma are more diverse. In Chelonopsis, pollen is taxonomically useful at the sectional level, and some grains provide enough characters for species delimitation. The potential pollination ecology of cellular hairs on the anthers of Chelonopsis and Bostrychanthera is also briefly discussed.  相似文献

Presently the only keys available for identification of genera of Anthonomini are limited to those of the United States of America and Canada. A dichotomous key is presented to identify all genera of Mexican and Central American Anthonomini. Previous keys do not include the genera Achia, Botanebius, Loncophorus, Loncophorellus and Melexerus. A brief synopsis is given for each genus and photographs of representative species are included.  相似文献

1. An electrophoretic key is described, based on enzyme relative mobility, to distinguish eight species of Egyptian mosquito adults. 2. Using horizontal starch gel electrophoresis, five different enzyme assays unambiguously separated Culex pipiens L., Cx antennatus (Becker), Cx pusillus Macquart, Aedes caspius (Pallas), Culiseta longiareolata (Macquart), Uranotaenia unguiculata Edwards, Anopheles multicolor Cambouliu and An.pharoensis Theobald. 3. Diagnostic loci between species were: Ak-2, G6pd, alpha-Gpd, Gpi and 6-Pgd; the probability of correct diagnosis in each case was at least 0.989.  相似文献

A growth key for use in winter linseed Linum usitatissimum is described. The decimal key is based upon the principles outlined by the BBCH scale. This scale covers the following main development stages in winter linseed: germination and emergence, leaf development, basal branching, stem extension, inflorescence development and emergence, flowering and capsule formation, development of the seed and capsule, capsule and seed ripening and stem senescence. These are subdivided into secondary stages. The key aims to provide farmers and advisers with clear guidance on appropriate growth stages for treatment of winter linseed crops and its' use is discussed with particular reference to agro-chemicals. Botanical illustrations are presented, based on samples taken from winter linseed crops covering the main growth stages.  相似文献
