[目的] 为了了解千里岩岛附近海域浮游植物状况。[方法] 以2015年秋季在该海域的监测数据为基础,并结合2013年调查数据,分析该海域浮游植物的变化情况。[结果] 2015年秋季千里岩岛海域发现浮游植物37种,由硅藻和甲藻组成,平均密度为3.23×105个/m3,监测区主要的优势种为圆筛藻(Coscinodiscus sp.)和虹彩圆筛藻(Coscinodiscus oculusiridis),多样性指数为2.13~3.42,平均为2.74。[结论] 与2013年调查数据比较,千里岩岛海域浮游植物种类数、密度和多样性指数有所增长,分析原因可能是由于调查季节不同。 相似文献

广东硇洲岛潮间带蟹类的组成及生态分布 总被引:2,自引:0,他引:2
经对硇洲岛潮间带蟹类进行调查,共获蟹类63种,分隶于11科、34属,其中硬相20种,软相43种。硇洲岛蟹类属于南海蟹类区系的成分,几乎完全是热带及亚热带性质。该文对其组成和生态分布进行了详细分析。 相似文献

在妈祖故乡湄洲岛元宵"闹妈祖"习俗活动中,舞蹈活动颇具特色。它是古代信仰物化形态的一种遗留,也是一种逐渐形成的自我调整机制。这些传统习俗依旧存在于莆田湄洲岛民众生活之中,并且随着时代的发展,更加丰富多样,呈现出祭神谢恩、群聚交际、宣传教化、娱乐健身以及新时期增加的促进两岸及海内外文化交流等社会功能。 相似文献

2008年6-10月对浙江秀山岛潮间带大型底栖动物进行了调查,共采集到大型底栖动物51种,隶属于4门、7纲、33科、41属。其中,软体动物19种,占37.26%;甲壳动物28种,占54.90%;多毛类3种,占5.88%;其他无脊椎动物只有海葵1种,占1.96%。潮间带大型底栖动物的生物量大小比较:九子沙滩(47.99g/m2)滑泥公园(32.23g/m2)海岙码头(7.78g/m2)兰山码头(5.34g/m2),而物种多样性(H')大小依次为滑泥公园(2.98)、九子沙滩(2.78)、海岙码头(1.55)、兰山码头(1.34)。研究认为秀山岛潮间带湿地越来越多用于旅游开发和临港工业建设可能是大型底栖动物物种多样性较低的主要原因,且临港工业建设对潮间带大型底栖动物群落结构的影响比用于旅游开发所产生的影响大,特别是物种数减少较明显。 相似文献

A small collection of fishes from the Bonaparte Seamount (15°40′S, 6°55′W, 130 km west of Saint Helena Island, least depth 105 m), comprising 14 specimens from nine species in eight families, is described. This appears to be the first collection of fishes reported from the seamount. In addition, seven new records for St Helena (15°58′S, 5°43′W) are reported as well as additional specimens of several rarely caught endemics. The scorpaenid Pontinus nigropunctatus, previously known only from St Helena, is now also reported from Bonaparte Seamount while the serranid Holanthias fronticinctus, also considered a St Helena endemic, has been found to comprise 20% of the diet of yellowfin tuna (Thunnus albacares) at the Seamount. The carangid Decapterus muroadsi which was previously recorded in the Atlantic only at St Helena is now also recorded from the Bonaparte Seamount. A second specimen of the primarily Indo-Pacific carangid Uraspis helvola is recorded from St Helena (third record for the Atlantic). Particularly interesting new records at St Helena, which represents significant range extensions, are of Corniger spinosus (Holocentridae), and of Carangoides ruber and Seriola fasciata (Carangidae). The potential role of shallow seamounts around Ascension and St Helena as ‘stepping stones’ between the two islands is discussed. 相似文献

A collection of eight species of terrestrial isopods from lava and cave sites on Ascension Island is described. Two species, Niambia longiantennata (Platyarthridae) and Elumoides coecus (Eubelidae), are described as new. Atlantoscia alceui Ferrara and Taiti (Philosciidae) is considered to be a junior synonym of A. floridana (Van Name) and the genus Ocelloscia Schultz and Johnson of Atlantoscia Ferrara and Taiti. At present the oniscidean fauna known from Ascension Island consists of 13 species. 相似文献

Over 8000 amphipods were examined from coastal (primarily intertidal) and anchialine pool habitats of Ascension Is. Twenty-seven species, of which 14 are undescribed, were identified. Comparison of species from Ascension with amphipods found in possible source areas suggests that most colonization of the island by these animals has been via the Benguela Current. Possible western Atlantic faunal contributions are significantly lower than for other marine taxa that have been studied at Ascension, all of which are generally characterized by having dispersive larval stages. The high proportion of apparently endemic species, which exceeds that described for amphipods of other oceanic islands, is probably due to both the island's isolation and incomplete faunal surveys in possible source areas. Amphipod species diversity is low, a probable consequence of the size, isolation, youth and low habitat variability of Ascension Is. Consistent with other Atlantic islands that have been studied, nestlers predominate (56% of the species), with tubicolous species (33%) of secondary importance and inquilines (11%) making only a minor contribution. Three species occur in the anchialine pool habitat. Rather unexpectedly, caprellid amphipods are absent. 相似文献

Seventeen species of Tardigrada from lakes and catchments on Signy Island, South Orkney Islands, are described. Two species, Echiniscus punctus and Isohypsibius laevis are new to science, and two, Oreella minor and Pseudechiniscus suillus, are new to the Signy Is. records. 相似文献
