A faunistic analysis of Macrolepidoptera from complex notophyll vine forest,North Queensland,Australia

Collections of Macrolepidoptera were made in complex notophyll vine forest and its derivatives growing on basalt soils near Atherton, Queensland, Australia. Light trapping was conducted over two periods of about 3 weeks each in the wet and dry seasons of 1996-97. A total of 15452 specimens belonging to 835 species were taken. Almost 94% of species could be identified to genus, with 72% determined to species level. The species collected represent about 17% of the total Australian fauna in families considered, suggesting between 20% and 30% of the Australian fauna occurs in this habitat type. The proportions of major families in the sample reflected the composition of the Australian fauna, but at a finer level of classification an imbalance was evident, with entire tribes and even subfamilies absent. These were mostly those associated with eucalypt forest or with principally southern distributions. The fauna was characterized by a strong Oriental region element but, at least in the Geometridae, there was an equally significant endemic element. In order to understand properly the biogeographic implications of this study, the need for similar studies in other nearby habitats, especially lowland mesophyll rain forest, is indicated.     

From the subantarctic to the subtropics: a revision of the Davacaridae Kethley, 1977 (Acari: Trigynaspida: Mesostigmata) with the description of a new genus and three new species

The family Davacaridae is shown to consist of at least two genera (Davacarus Hunter, Acanthodavacarus n. gen.) and four species that are distributed from subantarctic islands (D. gressetti Hunter) to Tasmania (D. reginaldi n. sp.), and to mainland Australia (D. lindquisti n. sp., A. klompeni n. sp.) at least as far north as the subtropical rainforests of south-east Queensland. These mites share a number of striking synapomorphies including the paedomorphic retention of the deutonymphal pattern of sclerotized plates in the adult, a secondary thickening of the cuticle around those plates and a lateral cheliceral excrescence that adheres to the cheliceral teeth. Species of Davacarus have lost the pregenital shield, have an intricate endogynium and four pairs of large, sessile opisthosomal glands; species of Acanthodavacarus have a pregenital shield with a pair of setae and two pairs of hypertrophied opisthosomal glands on short horn-like protrusions.     

A new genus and six new species of the Parabathynellidae (Bathynellacea,Syncarida) from the Kimberley region,Western Australia

Six new species of a new genus of the Parabathynellidae are described from the Kimberley Region, Western Australia. The erection of the new genus, Kimberleybathynella gen. nov., is based on the two‐segmented antenna, the partial fusion of the second and third segments of the maxilla, and the setal condition of the uropodal exopodite, where the outer seta is longer than the inner one. The one‐segmented exopodite of thoracopods I–VII and hemispherical form of male thoracopod VIII suggest the close relationship of Kimberleybathynella to the genus Atopobathynella.     

Phylogenetic relationships within Amphiglena Claparède, 1864 (Polychaeta: Sabellidae), description of five new species from Australia,a new species from Japan,and comments on previously described species

In reviewing material in Australian museum collections from the Australian and Japanese coasts it became clear that many specimens of Amphiglena did not match the diagnosis of any current species. To allow for variability observed among the specimens, and hence within nominal species, three specimens from each locality were included in a cladistic analysis, along with all currently accepted Amphiglena species, new characters, and a variety of apomorphic sabellins. This allowed a reassessment of the monophyly of Amphiglena, its sister group, and relationships with close taxa. Phylogenetic relationships among the species of Amphiglena are presented and six new species are described.     

澳大利亚灾害管理的特征及其启示

澳大利亚有较为完善的国家灾害管理体系,在灾害管理中,表现出:有较为先进的管理理念;法律依据充分;技术指导力度大、管理规范;以志愿者为特色的社会广泛参与;以风险管理为基本管理方式等特征.通过澳大利亚灾害管理的特征分析,作者认为,在中国灾害管理中应该重视:提高和统一管理者对自然灾害和灾害管理的科学认识;加强灾害法律法规体系和组织机构的建设;在减灾防灾工作中,除了应急响应和灾后重建工作外,还应加强灾前的预防和备灾工作;注重社区公共灾害意识和应急管理建设.     

澳大利亚科研诚信管理探析

全球范围内的科研诚信管理越来越重要,尤其是随着机构间和国家间的合作越来越频繁.由于研究经费的申请和论文的发表竞争日趋激烈,科研诚信管理的风险也随之加大.科研管理供应链上的所有参与者,包括政府、基金资助机构、研究机构、研究人员以及学生都应该被纳入科研诚信管理体系.该文分别从政府和机构层面对澳大利亚科研诚信管理结构和政策进...     

引种到我国的蓝桉与原产澳洲的蓝桉木材生态解剖学研究

用光镜及扫描电镜对不同生境下的蓝桉木材结构进行了解剖学观察，比较了原产地及引种到我国后不同生境下蓝桉木材的结构的变化，其变化主要是木材组成分子数量特征的差异。     

澳大利亚民族认同初探

历史上,澳大利亚的民族认同经历种族认同和文化认同的发展,20世纪70年代以后随多元文化政策的推行,在共同国民意识、公民意识的基础上形成的国民认同才趋于独立和成熟。民族认同发展和演变的过程也是澳大利亚走向开放的、民主的、成熟的现代社会的过程。     

非资源消费型野生动物旅游风险感知研究：澳大利亚班布里海豚探索中心实证

通过对前往澳大利亚班布里海豚探索中心的访客进行调研,运用因子分析、K-means聚类分析、方差分析等定量方法,分析游客对在野外生境中接触海豚的风险感知程度及差异性。通过探索性因子分析,共识别和提取野生动物旅游风险感知量表的3个维度:体验质量风险、舒适性风险和身体安全风险。受访者感知程度最强为体验质量因子,其次为舒适性,最后为身体安全。运用K-means聚类分析方法,依据量表均值得分,将受访者分为3类:弱风险感知、强风险感知和中等风险感知,而样本总体对接触海豚风险感知程度归属为弱风险感知,认为接触海豚是相对安全的活动。通过独立样本t检验和方差分析,对比不同游客特征对野生动物旅游风险感知的差异性。结果发现,人口社会学特征中,除性别外,不同年龄、收入和家庭状况在风险感知程度上均存在显著性差异;旅游行为中,旅游经历、旅行同伴、消费额和停留时间对风险感知具有显著性差异,信息来源途径无显著性差异;满意度和重游意愿对风险感知都具有显著性差异。
