The marine flora of Panama remains poorly described to date, having been described from a few sporadic and species poor (<50 species) collections in the early half of the century and a couple of dedicated surveys in the latter half. With the exception of a few studies that have focused on particular genera or species, only a single marine floral survey has been published in the past three decades. In 1999 we collected marine algae from nearly 100 different collection sites along both coasts of Panama over a 10 month period of time. Over 1500 specimens have been curated, representing 250 Caribbean species and 117 Pacific species. This is an increase in algal diversity of approximately 100 and 50% for the Caribbean and Pacific flora, respectively, relative to Earle's compilation of 1972. We estimate that algal diversity in Panama may approach 450 species as the remaining 30% of the collection is identified and previous records are incorporated. Aspects of biogeography will be discussed in light of such extraordinary diversity over a relatively confined region.  相似文献

Spatial and temporal variation in the recruitment of the intertidal barnacle Chthamalus malayensis was examined over one year (September 2003-August 2004) on the equatorial shores of southern Peninsular Malaysia and Singapore. A nested sampling design was applied for the first time on these shores, over three spatial scales - hundreds of kilometres, kilometres to tens of kilometres and tens of metres - and temporal variation was determined through monthly sampling of recruits. Shores within 2° north of the equator on the East and West coasts of southern Peninsular Malaysia and the southern coast of Singapore were selected as study sites. Generally, all three coasts recruited throughout the year, with varying intensities. There was a clear regional pattern, where the largest number of recruits was found on the East Coast of Malaysia, and the least in Singapore. Analyses of variance (ANOVA) showed that variability occurred on the smallest scale, but only in nine of the twelve months examined, consequently resulting in significant temporal and spatial interaction. Calculated variance components indicated that small-scale variation accounted for most of the overall variability. The potential causes of the spatial and temporal patterns of C. malayensis recruitment, and implications on tropical-temperate comparisons will be discussed.  相似文献

A collection of polychaetes made by the author in December 1961 and April 1962 from a number of places on the coast of Ceylon was examined. Seven new species and one new subspecies are described and sixteen species are recorded new to the fauna of Ceylon. The holotypes and lectotypes have been deposited in the British Museum (Natural History).  相似文献

There has been no previous systematic statewide study of mosquitoes in Mississippi. This survey, resulting in the collection of over 400,000 specimens, was conducted by the authors from 2003 to 2007 throughout much of the state using CO2‐baited CDC light traps and larval dipping. In addition, a health department contract mosquito surveillance technician collected several thousand specimens from the state from 2001 to 2003. Lastly, specimens housed at the Mississippi State University Entomological Museum, obtained from previous surveys, were included as vouchers for species occurring in the state. The collection records and literature show 60 species as occurring or having occurred in Mississippi. Voucher specimens representing 57 of the 60 species discussed are deposited in the Mississippi Entomological Museum or in the U.S. National Museum of Natural History (USNM), Washington, D.C.  相似文献

Bird specimens collected by 19th century explorer and ornithologist Prince Maximilian of Wied-Neuwied form one of the foundation collections of the American Museum of Natural History in New York. However, parts of his collection remained in Germany and came to the Museum Wiesbaden. Since Wied described numerous new species without designating types, some of these specimens might be type material. Here we present a catalog of the 30 Wiesbaden specimens associated with him and discuss their potential type status. We conclude that 17 individuals in 11 species are potential type specimens that should be considered in future taxonomic work.  相似文献

The present catalogue lists the type specimens of land snail species, collected from Taiwan and deposited in the Natural History Museum, London. Thirty-seven nominal species described by Pfeiffer, Adams, Nevill, Moellendorff, Godwin-Austen and Gude were traced. I present here information on type status, collection data obtained from the registers and labels of each collection, and annotations on the current taxonomic affiliation. Lectotypes of 28 nominal (sub)species were newly designated. One holotype was fixed originally and two holotypes newly fixed by monotypy. Syntypes of two species and paralectotypes of three species were also discovered in the Museum. No specimen of the species Pupina adamsi Sowerby, 1878, which was supposed to be deposited in the NHM, was found. Pictures of the name-bearing types are provided for further research on biodiversity of the island.  相似文献

天主教传教士Pierre Marie Heude(1836-1902)1867年自法国来到中国,他特别钟情于自然历史研究,把几乎所有的精力倾注于他在东亚地区的标本收藏上。1868年,他在现上海市郊的徐家汇建立了一座博物馆并收藏大量的动物标本。1933年徐家汇博物馆被震旦大学(现复旦大学)接管,并建立了一座新馆,更名为震旦博物院(欧洲称为Musee Heude),在Heude收藏的标本中,一部分是他在菲律宾,印度尼西亚,日本,印度及中国等地区探险时采集的,而绝大多数标本则是他通过各种方法联络各国同僚收集而来,在他死后,由他的接班人Courtois和Sowerby等继承了他的研究,1952年,上海自然历史博物馆接收了原震旦博物院,1958年原震旦博物院的标本被送至上海自然历史博物馆和中国科学院 研究所收藏。源自原震旦博物院的哺乳动物头骨标本可能是目前仍保存在国内有关亚洲地区收藏数量最大的一部分,然而,由于历史久远和中国近代变迁等因素的影响,Heude当时收藏的原始记录资料和标本标签大多遗佚或破损,使这批具有极高学术价值的头骨标本一直在标本馆中沉睡了一百多年。2000年4月中旬至5月中旬,作者将存放在上海和北京的所有兽类头骨标本进行了整理,重新进行标识和编目,经整理,共清理出兽类头骨2139件,根据Heude当时的分类,共查出模式标本188件(其中正模54,副模6,配模79,余模49),用红色圆点在模林标本上进行了标记,并将其名写于其上,尽管Heude标本中模式标本绝大多数为同物异名,这在一定程度上降低了它们的价值,但仍有一部分模式标本是名符其实的,如Bubalus mindorensis和Sus cebifrons等。在本文中,作者按现代分类顺序进行排列,并将保存于上海和北京两地的标本分开排列,以便于查找,同时用现代学术界认可的种名,在每一种名之后,分别列出标本中雌,雄个体,亚成体和性别不明标本的数量,如3.4.7+5表示,标本中有3个雄性成体,4个雌性成体,7个亚成体和5只性别不明个体。在种名的下面,按Heude在标本上标识的种名进行排列,在种名后是作者名和在著作中进行描述的时间,模式标本排列在前,其它标本在后。目录中的地名来自Heude在头骨上的标记,在目录最后列出了所有在目录中出现的地名。Heude在标签和头骨上书写的地名,可能是他根据当地口音或其他方式所确定,多数不是学术上公开使用的有效名称,给现在及将来使用带来诸多不便,因此在研究历史文献的基础上尽可能地附上了这些地名的现代名称。  相似文献
