ABSTRACT Parasitoid wasps of the subfamily Hyptiogastrinae (Gasteruptiidae) are known to lay eggs in the nests of solitary bees and wasps. Their larvae are considered predator-inquilines, consuming the host’s eggs and larvae and then the nest provisions. Pseudofoenus extraneus is endemic to Fiji, and the only member of the subfamily Hyptiogastrinae known to have colonised the archipelago. The host relationships and oviposition sequence of this species have not been previously reported. We show that the primary host is the halictine bee Homalictus fijiensis and describe P. extraneus behaviour around Homalictus nest aggregations and the entering of host nests. Wasps were observed entering Homalictus nests on nine occasions, as well as perching near nests and antennating nest entrances. The high abundance of H. fijiensis in Fiji may help to explain how a parasitoid was able to successfully invade such a remote oceanic archipelago as Fiji.
摘要拟寄生蜂属拟寄生蜂亚科(拟寄生蜂科)在独居蜂和胡蜂的巢中产卵。它们的幼虫被认为是掠食性昆虫,吃掉宿主的卵和幼虫,然后再吃巢穴的食物。外假腹蛇是斐济特有的,是已知的唯一在群岛上定居的假腹蛇亚科成员。寄主关系及产卵顺序未见文献报道。结果表明,其主要寄主为斐济家蜂(Homalictus fijiensis),并描述了外扁蜂在斐济家蜂巢聚集和进入寄主巢周围的行为。有9次观察到小黄蜂进入家蝇巢,在巢附近栖息,并在巢口触须。斐济人在斐济的高丰度可能有助于解释一种拟寄生虫是如何成功入侵斐济这样一个遥远的海洋群岛的。

ABSTRACT Two new species of Cloacina (Nematoda: Strongyloidea) are described from the stomach of the red kangaroo, Osphranter rufus. Cloacina xericola sp. nov. is described from a single locality, Menzies, in Western Australia. It differs from all congeners in having a highly recurrent vagina, six leaf crown elements, a lack of bosses in the lining of the oesophagus and extremely long spicules. Cloacina eris sp. nov. is most closely related to C. ares Beveridge, 1998 in the features of the buccal capsule and oesophagus, but differs in the position of the deirid, being posterior to the nerve ring in the new species, as well as in the form of the spicule ala which diminishes towards the tip in the new species, the greater length of the female tail, and the convoluted vagina of the new species. Cloacina eris is reported from both Western Australia and Queensland and at one locality in western Queensland, both C. eris and C. ares co-occur. Additional geographical records are provided for C. ares.

ABSTRACT This paper is an ethnographic study of Indigenous bird foraging post-European settlement of the Lower Murray in rural temperate South Australia. The Aboriginal people of this region have developed unique relationships with the landscape, reflecting the retention of some pre-European Indigenous practices and the development of new traditions. Aboriginal bird foraging practices after British settlement in 1836 were not just relics of a pre-European past but the product of cultural forces that shaped a modern Indigenous identity. Analysis of the continuity of bird foraging adds to the understanding of contemporary Aboriginal use and perception of the Australian landscape.
摘要:本文对欧洲移民后南澳大利亚温带乡村下墨累地区的土着鸟类觅食行为进行了人种志研究。这一地区的土著居民与这一景观形成了独特的关系,反映了一些前欧洲土著习俗的保留和新传统的发展。1836年英国殖民后,土著鸟类的觅食行为不仅是前欧洲时代的遗迹,而且是塑造现代土著身份的文化力量的产物。对鸟类觅食的连续性的分析增加了对当代土著对澳大利亚景观的利用和感知的理解。

ABSTRACT A new species of the Subuluridae (Nematoda: Ascaridida) Labiobulura lengguruensis n. sp. is described from the caecum and colon and two new species of the Chabertiidae: Cloacininae (Nematoda: Strongylida) Paralabiostrongylus tuberis n. sp. and Dorcopsinema amplum n. sp. are described from the stomachof the macropodid marsupial Dorcopsis muelleri (Lesson, 1827) (Mammalia: Macropodidae) in Papua Indonesia. Labiobulura lengguruensis differs from all congeners in having a simple denticle associated with each labial lobe of the buccal capsule. Paralabiostrongylus tuberis can be distinguished from its congeners in by the position of the deirid and the form of the dorsal ray and genital cone. Dorcopsinema amplum can be distinguished from its congeners by the length of the spicule, the morphology of the appendages on the ventral lip of the genital cone, the position of the lateral branches of the dorsal ray, the shape of the female tail, the morphology of the vagina and the size of the eggs.The known nematode fauna of D. muelleri is summarised. The finding of three species of Dorcopsinema each in a different geographical locality suggests the possibility of allopatric speciation. A revised key to the species of Dorcopsinema is given.
摘要在印度尼西亚的大足类有袋动物Dorcopsis muelleri (Lesson, 1827)(哺乳动物:大足科)的胃中发现了一新种(线虫纲:蛔虫纲)长唇虫(Labiobulura lengguruensis n. sp.)和二新种:Cloacininae(线虫纲:圆线虫纲)。在唇囊的唇叶上有一个简单的小齿,与所有的同类不同。结节旁圆线虫可以从它的同类中区分出来,从它的脊线的位置和背线和生殖锥的形式。从针状体的长度、生殖锥腹唇上附属物的形态、背射线侧支的位置、雌性尾巴的形状、阴道的形态和卵的大小,都可以将其与同类区分开来。总结了已知的木氏线虫区系。在不同的地理位置发现了三种Dorcopsinema,表明可能存在异域物种形成。给出了Dorcopsinema的一种修订的键。

ABSTRACT Litoria cyclorhyncha is a hylid frog native to southwest Western Australia (WA). It was first recorded in South Australia (SA) in 2000 and has established a breeding population in Streaky Bay on the western Eyre Peninsula since at least 2011. L. cyclorhyncha is a relatively large predatory frog that presents a potential threat to fauna and ecosystem processes in SA and eastern Australia. This study examines the invasion history and current and potential future distributions of this frog using historical records, field surveys and species distribution modelling (SDM). The historical records in SA suggest human-assisted dispersal through transport networks. Field surveys throughout the Eyre Peninsula during 2016–2017 detected three native species of frogs but no additional breeding populations of L. cyclorhyncha outside of Streaky Bay. Within Streaky Bay, frog abundance appears to be concentrated around permanent water bodies, but the species is also well established in urban habitats. SDM suggests that suitable environmental conditions exist for L. cyclorhyncha in southern and eastern Australia. This, and the frog’s ability to disperse over long distances, suggests considerable potential for the species to become invasive. As L. cyclorhyncha has potential to significantly impact biodiversity and ecosystems, management strategies are urgently needed.
Litoria cyclorhyncha是一种原产于西澳大利亚西南部的杂交蛙。它于2000年在南澳大利亚(SA)首次被记录,至少从2011年起就在艾尔半岛西部的条纹湾建立了一个繁殖种群。L. cyorhyncha是一种相对较大的掠食性蛙类,对南澳和澳大利亚东部的动物和生态系统过程构成潜在威胁。本研究利用历史记录、野外调查和物种分布模型(SDM)分析了该蛙的入侵历史以及当前和未来的潜在分布。南非的历史记录表明,人类通过交通网络辅助传播。2016-2017年在艾尔半岛的实地调查中发现了3种本地蛙类,但在条纹湾以外没有发现L. cyclorhyncha的繁殖种群。在条纹湾,青蛙的丰度似乎集中在永久水体周围,但该物种也在城市栖息地建立了良好的基础。SDM表明,澳大利亚南部和东部存在适宜的环境条件。这一点,再加上蛙类远距离分散的能力,表明该物种极有可能成为入侵物种。由于环孢草对生物多样性和生态系统具有潜在的重大影响,因此迫切需要采取相应的管理策略。

ABSTRACT Temperatures in South Australia have risen 0.5–1.5°C post-1950, a trend expected to drive ecological change. However, climate sensitivity, landscape resilience and management priorities vary among regions. We classified the vulnerability of South Australian plant assemblages to climate change in a framework that combines climate sensitivity and resilience. Generalised Dissimilarity Models (GDMs) of plant species composition were trained with species occurrence records from field plots. Resilience was represented by the proportional remnancy of native vegetation surrounding each location. Landscapes were classified using bivariate quantiles. Mean annual rainfall, summer maximum temperatures and spatial structure were important predictors of species turnover. GDMs (explaining 37–68% of deviance) were projected onto future climate scenarios to calculate sensitivity metrics. The Wheat Belt, mallee and Flinders Ranges were the most sensitive, representing a climatic transition characterised by rapid change in species assemblages. Southern Eyre Peninsula and western Kangaroo Island were classified as Resilient; the Mount Lofty Ranges, southern Flinders Ranges and eastern Kangaroo Island as Resistant; northern Eyre Peninsula and northern Flinders Ranges as Sensitive; and the Wheat Belt as Susceptible. The classification assists decisions on management priority and provenances or species selection for restoration and assisted migration in conjunction with other biodiversity measures.
自1950年以来,南澳大利亚的气温上升了0.5-1.5°C,这一趋势预计将推动生态变化。然而,气候敏感性、景观恢复力和管理重点因地区而异。我们在结合气候敏感性和恢复力的框架中对南澳大利亚植物组合对气候变化的脆弱性进行了分类。利用野外样地的物种发生记录对植物物种组成的广义不相似性模型进行了训练。恢复力由每个地点周围原生植被的比例残余来表示。采用双变量分位数对景观进行分类。年平均降雨量、夏季最高气温和空间结构是物种更替的重要预测因子。gdm(解释了37-68%的偏差)被预测到未来的气候情景,以计算敏感性指标。小麦带、马利和弗林德斯山脉是最敏感的,代表了以物种组合快速变化为特征的气候转变。艾尔半岛南部和袋鼠岛西部为弹性区;巍峨山脉、弗林德斯山脉南部和袋鼠岛东部为耐药山脉;艾尔半岛北部和弗林德斯山脉北部为敏感地区;小麦带易受影响分类有助于决定管理重点和种源或物种选择,以便与其他生物多样性措施一起进行恢复和辅助迁移。

ABSTRACT This paper is a literature review of the use of birds in the Indigenous material culture of the Lower Murray River region in temperate South Australia, as observed in the early years of British colonisation. This record is augmented with additional data from fieldwork in the 1980s and early 1990s. It was found that Aboriginal people in this region made artefacts incorporating avian materials based upon their perceived physical and cultural properties. Analysis of material culture with respect to birds contributes to the understanding of Aboriginal use and perception of the Australian landscape.
摘要:本文回顾了英国殖民初期在温带南澳大利亚的墨累河下游地区土著物质文化中鸟类的使用情况。这一记录在20世纪80年代和90年代初的实地调查中得到了补充。研究发现,这一地区的土著居民根据他们感知到的物质和文化属性,制作了含有鸟类材料的人工制品。对鸟类的物质文化分析有助于理解土著居民对澳大利亚景观的利用和感知。

ABSTRACT The natural flow regime of the Murray River in south-eastern Australia has been fundamentally altered through regulation and extraction, with fewer, shorter floods, changing seasonality of flows and reduced floodplain connectivity. Ecosystems which evolved over millenia show serious stress and decline under the regulated regime. Environmental water allocations being returned to Murray Valley ecosystems to halt the decline and improve river health are not sufficient to re-create missing floods, but aim to mimic key elements of the natural water regime. For floodplain vegetation communities, the missing element is seasonal water availability to maintain condition of mature trees and trigger germination of seedlings. Dominant perennial vegetation species river red gum (Eucalyptus camaldulensis), black box (E. largiflorens) and lignum (Muehlenbeckia florulenta) suffered significant stress and death during the severe Millenium drought (2000–2010), but drought-breaking floods in 2010–2012 replenished soil moisture reserves. A new generation of seedlings germinated, and many environmental watering projects now focus on enhancing survival of these seedlings. Previous studies suggested that timing of phenological stages can indicate key timing for beneficial delivery of environmental water. These findings are being tested at Lower Murray Valley sites, to identify optimum timing for watering to support recovery in floodplain vegetation communities.
澳大利亚东南部默里河的自然水流状况已经通过调控和开采从根本上改变了,洪水减少了,时间缩短了,流量的季节性改变了,泛滥平原的连通性也降低了。经过几千年进化的生态系统在管制制度下表现出严重的压力和衰退。将环境水分配回默里河谷生态系统,以阻止下降并改善河流健康,这不足以重现消失的洪水,但旨在模仿自然水制度的关键要素。对于洪泛平原植被群落来说,缺少的要素是维持成熟树木状态和触发幼苗发芽的季节性水分供应。2000-2010年千禧年干旱期间,优势多年生植被河红桉(Eucalyptus camaldulensis)、黑箱木(E. largiflorens)和木(Muehlenbeckia florulenta)遭受了严重的胁迫和死亡,但2010-2012年的抗旱洪水补充了土壤水分储备。新一代的幼苗发芽了,许多环境灌溉项目现在都集中在提高这些幼苗的存活率上。以前的研究表明,物候阶段的时间可以指示环境水有益输送的关键时间。这些发现正在墨累河谷下游地区进行测试,以确定最佳的浇水时间,以支持洪泛区植被群落的恢复。
