广东省榕树虫瘿蓟马种类及营瘿蓟马寄主专一性调查

2013年对广东地区榕树虫瘿中的蓟马种类进行了调查,共发现榕母管蓟马Gynaikothrips ficorum(Marchal)、榕管蓟马Gynaikothrips uzeli(Zimmerman)、榕端宽管蓟马Mesothrips jordani Zimmermann、拉马棘腿管蓟马Androthrips ramachandrai Karny和黄胫棘腿管蓟马Androthrips monsterae(Moulton)5种管蓟马科种类,其中黄胫棘腿管蓟马为中国新纪录种。榕母管蓟马和榕管蓟马为营瘿蓟马,诱导初始虫瘿具有寄主专一性,榕母管蓟马是细叶榕Ficus microcarpa初始虫瘿的诱导者,而榕管蓟马仅在垂叶榕Ficus benjamina Linn.上诱导形成虫瘿;但当两种榕树种植在一起时,榕母管蓟马和榕管蓟马偶尔会入侵到对方成熟虫瘿中并与之生活在一起。榕端宽管蓟马属于盗寄生种类,而拉马棘腿管蓟马和黄胫棘腿管蓟马主要捕食营瘿蓟马的幼体(包括卵、若虫和"蛹"),三者均为寄居性蓟马,无寄主专一性。

Revision of the genus Australimyza Harrison (Diptera: Australimyzidae)

Abstract.  The species of Australimyza Harrison are revised and the saprophagous larvae are described for the first time. The phylogenetic analysis revealed two species groups and one ungrouped species. One species group is distributed in New Zealand and associated subantarctic islands; all other species occur in Australia. Four new species, A. glandulifera , A. kaikoura , A. mcalpinei and A. victoria , are described, A. anisotomae is synonymized with A. australensis and a neotype is designated for the latter species. A lectotype is designated for A. macquariensis .     

Morphological and molecular characterization of two novel species of Agaricus section Xanthodermatei

Agaricus specimens collected in France belong to two novel entities resembling small forms of A. moelleri and A. xanthodermus, two common species in section Xanthodermatei. Molecular (IT1+ITS2 DNA sequence) and morphological comparisons between eight presumed similar taxa of the section support the elevation of both entities to species rank. The new entities are described as A. parvitigrinus and A. xanthodermulus. They form a group with A. laskibarii, a rare species also recently described from France, and A. californicus, a North-American species. The well known A. moelleri and A. xanthodermus are the most related species among the studied sample. Like other species of the section, both new species have a phenolic odor and are probably toxic.

葱属根茎组8种21居群植物的核型研究

对葱属根茎组Allium sect.Rhiziridium的8种21个地方居群的核型进行研究,以期为解决该组的种间亲缘关系和物种进化机制提供依据。贺兰韭A.eduardii和阿拉善韭A．flavovirens2个种的核型以及辉韭A．strictum的六倍体核型均属首次报道。研究结果表明：贺兰韭A.eduardii、阿拉善韭A.tlavovirens、北韭A.lineare、蒙古韭A.mongolicum和滩地韭A．oreoprasum的各居群均为二倍体,核型类型为Stebbins的2A型;韭A．tuberosum和野韭A.ramosum的各个居群均为四倍体,核型类型为2A型：辉韭A．Jtrictum的4个居群均为六倍体,核型类型为2B型。通过研究可以得出如下推论：（1）该组植物中存在着大量的多倍体或多倍体系列,染色体数目变化与物种进化具有密切相关性,多倍化可能是根茎组植物核型进化的重要机制之一;（2）随体染色体多为st或t染色体,均位于短臂末端;（3）可以认为辉韭是以增加倍性来克服该物种扩大新的生存空间所带来的困难;（4）现今栽培的韭可能是由野生的二倍体韭和四倍体韭经过长期人工驯化而来的,现今栽培的三倍体韭可能是二倍体韭和四倍体韭杂交而来,并且以无性繁殖方式保存三倍体类群的存在。     

The taxonomy and distribution of Azolla species in southern Africa

The three Azolla species which occur in southern Africa, A. pinnata var. pinnata, A. nilotica and A. filiculoides are identified and their distributions illustrated. The endosymbiotic cyanobacterium Anabaena azollae occurred in dorsal leaf lobe cavities of all three species. The first two species are indigenous to southern Africa, whilst the third, A. filiculoides , is an introduced species from North America. Possible means whereby this species could have been introduced are discussed.

Genetic,ecological, and behavioural divergence between two sibling snapping shrimp species (Crustacea: Decapoda: Alpheus)

Examination of genetic and ecological relationships within sibling species complexes can provide insights into species diversity and speciation processes. Alpheus angulatus and A. armillatus, two snapping shrimp species with overlapping ranges in the north-western Atlantic, are similar in morphology, exploit similar ecological niches and appear to represent recently diverged sibling species. We examined phylogenetic and ecological relationships between these two species with: (i) sequence data from two mitochondrial genes (16S rRNA and COI); (ii) data on potential differences in microhabitat distribution for A. armillatus and A. angulatus; and (iii) data from laboratory experiments on the level of reproductive isolation between the two species. DNA sequence data suggest A. armillatus and A. angulatus are sister species that diverged subsequent to the close of the Isthmus of Panama, and that haplotype diversity is lower in A. armillatus than in A. angulatus. Both species are distantly related to A. heterochaelis and A. estuariensis, two species with which A. angulatus shares some similarities in coloration. Ecological data on the distribution of A. angulatus and A. armillatus from two locations revealed differences in distribution of the two species between habitat patches, with each patch dominated by one or the other species. However, there was no apparent difference in distribution of the two species within habitat patches with respect to microhabitat location. Ecological data also revealed that heterospecific individuals often occur in close proximity (i.e. within metres or centimetres) where sympatric. Behavioural data indicated that these species are reproductively isolated, which is consistent with speciation in transient allopatry followed by post-divergence secondary contact. Our data further resolve taxonomic confusion between the sibling species, A. armillatus and A. angulatus, and suggest that sympatry in areas of range overlap and exploitation of similar ecological niches by these two recently diverged species have selected for high levels of behavioural incompatibility.
