Managers of primate colonies seek to record colony data in a systematic way which will be helpful in daily management. Each colony develops individual record systems, tailored to its specific operations and budget. These diversified systems provide the base for a set of uniform record items, which enables information to be shared among institutions, and used for the overall management of a self-sustaining captive primate population, as well as for national planning of primate resources. The present report identifies basic information needed for local colony management and data items that require standard nomenclature. Such data will provide the basic demographic profiles unavailable at most primate colonies today.  相似文献

New chorological data are presented for 271 species and subspecies of vascular plants in the prefecture (nomos) Attikis, Greece, and recent changes in the flora and the phenology of refound species is briefly discussed. Four species are reported as new for the Greek mainland, 9 for the floristic region of Sterea Ellas (StE), 56 for the mainland of nomos Attikis, 12 for eparchia Attikis and 36 for eparchia Megaridos. Sixty-five taxa are reported as new for Mt Parnitha, 24 taxa for Mt Pendeli, 12 for Mt Imittos, 57 for Mt Kitheronas, 42 for Mt Pateras, 34 for Mt Pastra and 11 for Mt Gerania. The taxa in nomos Attikis (16) and on individual mountains in Attiki (14) for which only historical records are known but not recently confirmed are listed. The increase in the number of taxa during the last 20 years is also confirmed based on data from grid square maps which depict the numbers pre-2000 and as presently known.  相似文献

中国香港新记录的十个分类单元(英文)   总被引:1,自引:0,他引:1       下载免费PDF全文
中国香港位于热带北缘,其植被在历史上曾遭到大规模破坏,近几十年来逐渐恢复。香港植物标本采集有很长的历史,迄今为止已记录的维管植物超过2 170种,然而新种和新分布仍在不断增加。在最近的野外工作中,作者发现10种在香港新记录到的维管植物,分别是唇边书带蕨[Haplopteris elongata (Swartz) E. H.Crane]、雷公连[Amydrium sinense (Engl.) H. Li]、百足藤[Pothos repens (Lour.) Druce]、四川轮环藤(Cycleasutchuenensis Gagnep.)、山黑豆(Dumasia truncata SieboldZucc.)、倒心叶珊瑚[Aucuba obcordata (Rehder) Fu ex W. K. Hu et Soong]、竹叶榕(Ficus stenophylla Hemsl.)、长叶冠毛榕[F. gasparriniana var. esquirolii (H. Lév.Vaniot) Corner]、硬叶冬青(Ilex ficifolia C. J. Tseng ex S. K. Chen et Y. X. Feng)、假福王草[Paraprenanthes sororia(Miq.) C. Shih.]。雷公连属(Amydrium Schott)、山黑豆属(Dumasia DC.)和假福王草属(Paraprenanthes C. C.Chang ex C. Shih)为香港的新记录属。以上的发现不仅丰富了香港的植物区系,而且表明保护残存植被非常重要,且极小种群的保护也值得特别关注。  相似文献

A new name, that is Phyllanthus blancoanus, was proposed by Müller Argoviensis for Blanco's P. tetrander which, in turn, is a later homonym (Art. 53.2 of Shenzhen Code) of Roxburgh's P. tetrandrus (year of publication 1845 and 1832, respectively). We accepted to treat Phyllanthus blancoanus under the genus Nymphanthus ( as Nymphanthus blancoanus) according to a recent molecular data. Blanco's name is neotypified on a US specimen lacking original materials (Arts. 9.4 and 9.8 of Shenzhen Code).  相似文献

To document a relation between abundance of arboreal, predatory tiger beetles, their ant prey, and extrafloral nectaries attracting the ants, we gathered data from more than 10 species of native and introduced trees and large, tree‐like perennial plants in Lanao del Sur Province, Mindanao, Philippines. All specimens of tiger beetles (two Tricondyla and two Neocollyris species, all endemic to the country) were noted on five tree species characterized by presence of extrafloral nectaries, including three alien/invasive and two native ones. Invasive Spathodea campanulata and native Hibiscus tiliaceus were the most inhabited ones (respectively, 56% and 19% of beetles). Presence of tiger beetles on these trees most probably depends on high abundance of ants, which are typical prey for arboreal Cicindelidae, while occurrence of ants can result from presence of extrafloral nectaries on different parts of the plants. This suggests a new mutualistic insect–plant interaction between native and invasive species.  相似文献
