澳大利亚农业推广政策的演变及其对我国的启示

本文对澳大利亚近10余年来农业推广政策与推广服务方式演变的背景、具体内容及其存在的问题进行了客观的分析，对现阶段我国农业推广改革中如何调整政府在农业推广中的角色、改进推广方法、完善多元化的推广服务组织以及推广服务的商品化等问题提出了相应的建议。     

A revision of Bovichtus Cuvier, 1831 (Pisces: Bovichthyidae) from Australasia,with description of a new deepwater species from the New Zealand Subantarctic

The genus Bovichtus includes four species from the Australasian region, viz. B. variegatus Richardson, B. psychrolutes Günther, B. angustifrons Regan, and B. oculus n. sp. B. decipiens Regan and Aurion effulgens Waite are junior synonyms of B. variegatus and B. psychrolutes respectively. B. oculus, described from a specimen taken in 847–902 m on the Campbell Plateau in the New Zealand Subantarctic, is the first known deep water Bovichtus species. It differs from all congeners in having a very large eye (horizontal diameter <9·0 times in SL) and, alone with B. psychrolutes, has a patch of ctenoid scales on the body behind the pectoral fin base.     

The larval development of Petalomera japonica (Henderson) (Decapoda,Dromiidae) reared in the laboratory

The complete larval development of Petalomera japonica (Henderson) is described, based on laboratory rearing. The species has two zoeal stages and a megalopa. Detailed comparisons are made with other dromiid larvae, particularly those of Petalomera wilsoni.     

A new species in the genus Grandidierella Coutière (Crustacea: Amphipoda) from an Australian solar salt-works

Grandidierella propodentata sp. nov., a third Australian species of the genus, is described. It was collected from among algae in a hypersaline lagoon in Queensland. Sexual dimorphism of the uropods is reported for the first time in this genus.     

Occurrence of the trapdoor spider genus Moggridgea in Australia with descriptions of two new species (Araneae: Mygalomorphae: Migidae)

The occurrence of the trapdoor spider genus Moggridgea (Migidae) in Australia is reported, and two new species described: M. tingle n. sp. from southwest Western Australia and M. australis n. sp. from Kangaroo Island, South Australia. This is the first record of the subfamily Paramiginae from Australia. The historical biogeographic implications are discussed.     

Another inordinate fondness†: diversity of the tanaidacean fauna of Australia,with description of three new taxa

The shallow-water tanaidacean fauna of the Bass Strait has been the subject of recent intensive studies. The present paper extends this work into the deeper waters of the region, describing two new species and one new genus. The new species of the genus Paradoxapseudes has a combination of three maxillule palp setae, no plumose setae on the basis of pereopod 1 nor proximal serration on the antennal peduncle. The second species represents a new genus of the family Anarthruridae, having six marginal setae on the third maxilliped palp article and spines on the merus and carpus of the anterior pereopods. The high diversity of Tanaidacea in Australian waters is discussed. In particular, we conclude that Australian coasts suffer a diversity of immigration routes, have sufficient marine longevity, and afford such a diversity of available niches to have allowed multiple colonization and subsequent allopatric speciation of Tanaidacea. http://www.zoobank.org/urn:lsid:zoobank.org:pub:EE309A5A-E06D-416F-95BD-4C8D0D2BEB97     

Redescription of Alona macracantha Smirnov and Timms, 1983 and its assignment to Maraura gen. nov. (Cladocera: Anomopoda: Chydoridae)

Three new species of the harpacticoid family Ameiridae are described from clean sand at high water neap tide on St Martin's Flat, Isles of Scilly. Ameiropsis martinis sp. nov. appears most closely related to A. australis Kunz, 1975 Kunz, H. 1975. Copepoda Harpacticoidea aus dem litoral des sudlichen Afrika. 1 Teil. Kiel Meeresforsch., 31(2): 179–212.  [Google Scholar] but can be distinguished from it by the shape of the rostrum and the armature of the operculum, female genital field and the male P5 baseoendopodal lobe. Sarsameira parexilis sp. nov. was originally identified as S. exilis T. and A. Scott, 1894 Scott, T. 1894. Additions to the fauna of the Firth of Forth. Part IV. 12th Annual Report of the Fisheries Board for Scotland, : 231–270.  [Google Scholar] but the females can be distinguished from S. exilis by their smaller body size and shape of the caudal ramus whilst the males can be distinguished by the 12-segmented antennule and four setae on the P5 baseoendopodal lobe. Ameira longispina sp. nov. is unique within the “Ameira” complex of genera and species because of the marked elongation of the inner spine on the basis of the male P1. This species is tentatively placed in Ameira Boeck, 1865, but has features which indicate that it probably occupies an intermediate position between this genus and Psammameira Noodt, 1952. The previously unknown males of Sarsameira perezi Bodin, 1970 Bodin, P. 1970. Copépodes Harpacticoides marins des environs de La Rochelle 1. Especes de la vase intertidale de Chatelaillon. Tethys, 2(2): 385–436.  [Google Scholar] and Nitocra elegans (T. Scott, 1905 Scott, T. 1905. On some new and rare Crustacea from the Scottish seas. 23rd Annual Report of the Fisheries Board for Scotland, : 141–153.  [Google Scholar]) are also described.     

Taxonomic observations on the genera Xenocheira Haswell and Ericthonius Milne Edwards (Crustacea: Amphipoda) from Australian coastal waters

The type-species of the genus Xenocheira Haswell, X. fasciata Haswell, is redescribed (including the true male) from Tasmanian material. Pirlot's putative male X. fasciata from Indonesia is allocated to a new species, X. pirloti nom. nov. and K. H. Barnard's ‘X. fasciata’ from the Great Barrier Reef referred to Grandidierella gilesi Chilton. Another Xenocheira species from Western Australia is identified tentatively as X.? seurati Chevreux. Two new species of Ericthonius Milne Edwards are described, one from Tasmania (E. tacitus sp. nov.) and one from Western Australia (E. coxacanthus sp. nov.). The first record of E. pugnax Dana from mainland Australia is claimed for material from Western Australia. The taxonomic relationships of these species are evaluated and discussed.
