鸟类栖息地研究进展 总被引：3，自引：0，他引：3
从研究方法、栖息地选择、栖息地评价、栖息地破碎化等方面对鸟类栖息地的研究进行总结。鸟类栖息地研究常用的方法有条带取样法和0.04hm2圆形地块法等,近年来3S等技术的应用,提高了研究效率,拓展了鸟类栖息地的研究领域;鸟类对栖息地的选择大多以植被等环境因子为基础,在不同空间尺度及不同季节和生活史阶段,鸟类栖息地选择的影响因素各不相同;在鸟类栖息地选择研究基础上,对鸟类栖息地进行适宜性评价及等级划分,可以为鸟类栖息地保护和恢复提供理论依据;栖息地破碎化会对鸟类生存和鸟类行为产生影响,从而影响鸟类种群的营巢成功率、繁殖成功率及鸟类群落分布。从研究对象、方法、内容等方面对国内鸟类栖息地研究进行展望。 相似文献

In this study, immunohistochemical analysis has been performed using neuronal
markers (GAP43, NCAM and PGP 9.5) to characterize the epithelial invagination in the
medial wall of the olfactory pit in the chick embryos. At stages 26–27, the epithelial
invagination was primarily composed of characteristic round-shaped cells, which were
negative for neuronal markers. These cells were also found in the medial wall of the
olfactory pit at stage 24, whereas the epithelial invagination was not observed at any
stages other than stages 26–27. The possible relationship between the round-shaped cells
and the migratory cells is discussed. 相似文献

Normal tables of chicken embryo development are used to define specific stages of morphogenetic progression from the first cleavage divisions through hatching. Although established for the turkey and Pekin duck, the application of the normal tables of chicken embryo development to other birds of commercial and research importance needs be examined. Chicken, turkey, Japanese quail, and Pekin duck blastoderms from oviductal eggs showed differences in the rate of development that were inversely correlated with egg size. Oviposited eggs from these and additional species (goose, Muscovy and mule ducks, and Guinea fowl) were examined after 24 to 72 h of storage and at 6-h intervals up to 72 h of incubation. There was variation in the developmental stages of the blastoderm at the time of oviposition between and within the species and strains examined. Although it is recognized that the temporal rate of development will differ between different species and strains, the external features of any embryo in any given stage will be nearly identical. 相似文献
