褐藻77 K荧光特异性研究

测定了裙带菜、叉开网地藻、海带、囊藻、海蒿子、鼠尾藻、萱藻和水云等８种褐藻的７７Ｋ荧光光谱并同菠菜和红藻条斑紫菜作了比较。结果表明与红藻和高等植物明显不同,褐藻没有作为ＰＳＩ特征的７３０ｎｍ荧光峰。按荧光主峰的波长,可以分为二种类型：裙带菜、叉开网地藻、海带和囊藻的荧光主峰位于６９０ｎｍ,海蒿子、萱藻、水云和鼠尾藻的荧光主峰在７０５～７２０ｎｍ。这种７７Ｋ荧光特异性预示褐藻同高等植物之间在ＰＳＩ结构上的差异。

防污涂料的毒性及其对海洋环境的污染

在船舰、浮标、浮码头、输水管道等水下设施表面附着各种动植物,其中常见的有藤壶、贻贝、海蛸、牡蛎、苔藓虫等动物以及石菁、浒苔、裙带菜、水云等定生藻类。生物附着的过程是生物群落逐渐演替的过程。当物体浸入海水后,首先附着上去的是细菌,它们的繁殖速度很快,往往在几天内就能形成肉眼可见的菌层,以后附着的是硅藻和一些原生动     

广西柳州都乐溶岩(洞)群的新发现

都乐溶岩群,是当地贫下中农在生产建设中新发现的。它位于柳州市东南十二公里的都乐村。由于洞内的石灰华沉积(石钟乳、石笋、石柱、石花、石幔等)十分发育,景色幽美,于1974年国庆节前夕向广大工农兵开放游览。目前开放游览的洞穴有盘龙洞、水云洞和通天洞。这三个洞的总面积达六千多平方米。游览路程六百余米。这几个洞内的堆积物保存极为完好,尤其是石灰华之类的沉积形态无一损坏。为了进一步认识都乐溶岩群的地质现象,我们进行了短期的考察,现将考察所获作一简述。洞穴堆积简况     

问题解答

问:在植物界中,只有高等植物才有世代交替现象吗? 答:世代交替现象不光是高等植物都具有的生殖规律,它也存在于一部分低等植物中。例如:绿藻中的石莼、浒苔、几种刚毛藻,红藻中的石花菜、多管藻,褐藻中的海带、水云、网地藻、裙带菜、马鞭藻、黑顶藻、真菌中的异水霉,都有典型的世代交替现象。问:什么是等世代交替和不等世代交替? 答:等世代交替和不等世代交替是世代交替中的两种类型。等世代交替的植物,其孢子体和配子体在形态、大小及外观上是相同的,所不同的是孢子体为二倍数染色体的植物体,配子体是单倍数染色体的植物

Immature Stages of Neotropical Enochrus (Coleoptera: Hydrophilidae): E. (Methydrus) lampros Knisch, 1924 and E. (Hugoscottia) tremolerasi Knisch, 1922

The preimaginal stages of the Neotropical species E. (M.) lampros Knisch, and Enochrus (H.) tremolerasi Knisch, are described and illustrated for the first time. They are compared to the immatures of the Neotropical species E. (M.) vulgaris (Steinheil) and E. (Hugoscottia) scutellaris (Bruch), the Nearctic E. (M.) fimbriatus (Melsheimer) and E. (M.) pygmaeus nebulosus Say, and the Australian E. (M.) maculiceps (MacLeay). Bionomical notes on the two species are included.

Two new species of African Haemaphysalis ticks (Acari: Ixodidae), carnivore parasites of the H. (Rhipistoma) leachi group

Two new tick species belonging to the African Haemaphysalis (Rhipistoma) leachi subgroup, namely H. (R.) colesbergensis n. sp. and H. (R.) oliveri n. sp., are described. Haemaphysalis (R.) colesbergensis adults are easily differentiated from the other species of the H. (R.) leachi subgroup, including H. (R.) oliveri, by the spur on coxa IV, which is considerably longer than that on coxa III. The adults of the 2 new species are equal in size, but the dental formula of the hypostome of H. (R.) colesbergensis is 4/4 compared to 5/5 for H. (R.) oliveri. The dental formula of H. (R.) oliveri also distinguishes it from other ticks in the subgroup, namely H. (R.) leachi, H. (R.) elliptica, H. (R.) moreli, and H. (R.) punctaleachi (4/4 in these species), but not from H. (R.) paraleachi, which has a 5/5 dental arrangement. However, the average total length and width of H. (R.) oliveri males (2.47 x 1.20 mm) are considerably shorter and narrower than those of H. (R.) paraleachi males (3.81 x 1.79 mm). Similar differences in size apply to the females. Nymphs and larvae of H. (R.) colesbergensis and H. (R.) oliveri can be distinguished from those of other members of the H. (R.) leachi subgroup, as well as from each other, by a combination of the following characters: size and measurement ratios, length of posterodorsal and posteroventral spurs on palpal segment II, and number of denticles per file on the hypostome. Haemaphysalis (R.) colesbergensis is known only from South Africa, where it has been collected from domestic cats and dogs and medium-sized wild felids. Haemaphysalis (R.) oliveri is recorded only from Sudan, where it has been collected from small- to medium-sized wild felids and canids and an antelope. The hosts of the immature stages of H. (R.) colesbergensis are unknown, while nymphs of H. (R.) oliveri have been collected from rodents.     

A new classification for the subgenera of the genus Acanthophthirius Perkins,with descriptions of twelve new taxa (Acarina,Trombidiformes, Myobiidae)

The myobiid genus Acanthophthirius Perkins, to date comprising four subgenera, is reviewed and divided into just two subgenera, the nominate subgenus and Myotimyobia Fain. The male genital shield and female opisthogastric sclerites, which are here considered to be part of female genitalia, are adopted as the criteria for dividing the subgenera. These structures are essentially the same in form and position in the subgenus Acanthopthirius in its revised sense, while they are both more heterogeneous in species of the redefined subgenus Myotimyobia. The subgenera Acanthophthirius Fain and Chiromyobia Fain are thought to represent species-groups in the nominate subgenus, named respectively the etheldredae and miniopteri groups. The following one new subspecies and 11 new species are described: A. (A.) womersleyi eptesicus, A. (A.) glauconycteris, A. (A.) mauritaniensis, A. (A.) philetoris, A. (A.) otonycteris, A. (A.) steatocaudatus, A. (A.) nyctophilis, A. (M.) vagus, A. (M.) longus A. (M.) baueris, A. (A.) hesperopteris (female only) and A. (M.) pixonixeos (female only). A. (M.) hanensis is synonymised with A. (M.) namurensis, and A. (M.) capacini is emended to A. (M.) capaccinii and relegated to a subspecies of A. (M.) myotis. All the known and new species are assigned to their respective subgenera and shown in a table. Incongruent host-relationships of some of the mites are clarified, although not completely solved, by the introduction of the new classification for the subgenera.

大兴安岭的黄梅属地衣(英文)

本文报导了分布在大兴安岭的10种黄梅属(Xanthoparmelia)地衣,很多文献曾报导过中国的菊叶黄梅(X.conspersa),但是魏江春(1983)根据形态及化学两方面研究的结果指出,文献中的菊叶黄梅实际上分别是暗腹黄梅(X.tinctina)和淡腹黄梅(X.mexicana)。本文作者在大兴安岭北部釆到了真正的菊叶黄梅。本文还包括5个中国新记录种,它们是贴生黄梅(X.hypopsila),线形黄梅(X.lineola),新墨西哥黄梅(X.novomexicana),黑黄梅(X.tasmanica)和离心黄梅(X.centrifuga)。
