ABSTRACT The cestode, Bertiella musasabi Yamaguti, 1942 and four nematodes identified to at least genus level and adult specimens assignable to the Nippostrongylinae were recovered from nine of 20 individuals of Chiruromys forbsei Thomas, 1888. Five nematodes identified to at least genus level and adult specimens assignable to the Nippostrongylinae were recovered from 11 of 12 individuals of C. lamia (Thomas, 1897). Species of Parasabanema from C. forbsei and C. lamia, Parastrongyloides from C. lamia and Trichuris also from C. lamia could not be assigned to any known species. Hasanuddinia chiruromyos Smales, 2011a was previously reported from C. vates(Thomas, 1908). Helgenema lamia n. sp. differed from its congener H. keablei Smales, 2020 by its larger size, longer spicules and larger number of eggs in utero. Protospirura munimuniensis n. sp. from C. lamia was differentiated by having two denticles on each pseudolabium, males with the right spicule longer and more robust than the left, a V-shaped gubernaculum and six pairs of post cloacal papillae. Heligmonellids dominated the helminth assemblages of both hosts. Species richness, 80.6% species recovered for C. lamia,and 57% for C. vates was low in both hosts. Possible determinants of species richness were discussed.
摘要/ ABSTRACT摘要:从1888年的20只斑蝽(chirurromys forbsei Thomas)的9只个体中检出了1942年的musasabi Yamaguti小虫和4只鉴定为属级以上的线虫和可归属于Nippostrongylinae的成虫标本。从12只C. lamia的11只个体中发现了至少属水平的5种线虫和可归属于Nippostrongylinae的成虫标本(Thomas, 1897)。来自forbsei和C. lamia的parabanema种,来自C. lamia和Trichuris的Parastrongyloides种,以及来自C. lamia的Parastrongyloides种都不能归属于任何已知种。Hasanuddinia chiruromyos Smales, 2011a先前报道于C. vates(Thomas, 1908)。Helgenema lamia n. sp.不同于其同系物H. keablei Smales, 2020,它的体积更大,针状体更长,子宫内卵数量更多。原螺旋藻(munimuniprotospirura munimuniensis n. sp.)的分化特征为:每个假唇上有两个小齿,雄性的右针状体比左针状体长且结实,一个v形的管骨和6对后腔乳头。两种寄主的蠕虫组合中均以Heligmonellids占优势。物种丰富度在两种寄主中均较低,lamia恢复了80.6%,而vates恢复了57%。讨论了物种丰富度的可能决定因素。

ABSTRACT The determination of ovarian stages is essential for an understanding of reproductive biology and informing sustainable management of commercially caught marine organisms. This research developed improved microscopic assessment criteria for the prawn, Penaeus (Melicertus) latisulcatus, by reviewing microscopic criteria used in the literature and assessing cell composition of ovary tissue from 97 females. Whilst histological staging is not a new technique, this research outlines new development criteria for assessing ovary development stages in P. latisulcatus. A principal component analysis (PCA) was used with the microscopic classification system and showed distinct groups for each stage. Based on the proportion of cell types, distinct groupings were apparent, which corresponded to the main microscopic stages, in particular for stage 3 ovaries. This revised classification will improve the accuracy of ovarian staging techniques for P. latisulcatus and can be used as a guide for the interpretation and analysis of macroscopic stages during seasonal spawning events for the purpose of better informing fisheries management.
卵巢分期的确定对于理解生殖生物学和为商业捕捞海洋生物的可持续管理提供信息至关重要。本研究通过对文献中常用的对虾(Penaeus (Melicertus) latisulcatus)的显微评价标准进行综述,并对97只雌性对虾卵巢组织的细胞组成进行了评价。虽然组织学分期不是一项新技术,但本研究概述了新的发展标准来评估P. latisulcatus卵巢发育阶段。主成分分析(PCA)与显微分类系统相结合,显示出不同阶段的不同类群。根据细胞类型的比例,不同的细胞类型有明显的分组,这些分组与主要的显微阶段相对应,特别是第三阶段的卵巢。修订后的分类将提高大斑鲟卵巢分期技术的准确性,并可作为解释和分析季节性产卵过程中宏观分期的指南,以便更好地为渔业管理提供信息。

ABSTRACT Parasites in wildlife tend to be poorly studied in spite of the ecological roles they play, and even basic information such as the geographic distribution of the parasites and the hosts they infect or infest are not well known. For parasites that live within the host, part of the reason for this lack of information is that the hosts must be killed and dissected to determine which endoparasites they harbour, which has legal and/or ethical implications and limitations. These obstacles can be overcome by collecting and examining potential hosts that are found dead on roads or that are sacrificed as part of other non-related studies. In this study, our objective was to expand on our understanding of the gastrointestinal parasites of some common reptiles from an area in the vicinity of a study site in the Mid North region of South Australia by making use of snakes and large lizards that were found dead on roads or that were humanely killed for another study. Our study provides new locality and/or host species records for some parasite species.
尽管野生动物中的寄生虫发挥着重要的生态作用,但对它们的研究却很少,甚至连寄生虫及其感染或侵害的宿主的地理分布等基本信息也不清楚。对于生活在宿主体内的寄生虫,缺乏信息的部分原因是,必须杀死和解剖宿主,以确定它们所携带的内寄生虫,这有法律和/或伦理方面的影响和限制。这些障碍可以通过收集和检查在道路上发现的死亡或作为其他非相关研究的一部分而牺牲的潜在宿主来克服。在这项研究中,我们的目标是扩大我们对一些常见爬行动物胃肠道寄生虫的了解,这些爬行动物来自南澳大利亚中北部地区的一个研究地点附近的一个地区,利用在道路上发现的死亡的蛇和大型蜥蜴,或者是为了另一项研究而被人道地杀死的蛇和大型蜥蜴。我们的研究为某些寄生虫提供了新的地点和/或寄主物种记录。

ABSTRACT In 1891, three members of the Elder Scientific Expedition, led by Lawrence Wells O.B.E., undertook two exploratory traverses while the main party was travelling through the Far North West of South Australia. Following the common practice of the day at the southern apex of each traverse, Wells blazed his initials and date on a tree. One of these trees is known, with the westernmost having not been seen again until it was thought to have been found in 2005 when a search party found a tree with a partially healed scar. Wells was an accomplished surveyor and followed the common practice of the times by recording relatively precise latitude readings, but not longitude. While the route the main party took is well documented and well known, this second traverse is unknown. To recreate the route Wells took and provide some probability as to the location of this tree, a more novel approach was required. Specialist spatial software was developed for this study that compares the elevations and distances between sand ridges meticulously recorded by Wells, enabling recreation of his traverse, providing some certainty as to the location of this remote tree.
1891年,在劳伦斯·威尔斯o.b.e.的带领下,“老年科学探险队”的三名成员进行了两次探险穿越,而主要探险队正在南澳大利亚的远西北地区旅行。按照这一天的惯例,威尔斯在每次穿越的最南端把自己名字的首字母和日期刻在一棵树上。其中一棵树是已知的,最西端的那棵树直到2005年才被发现,当时一个搜索队发现了一棵部分愈合的伤疤。威尔斯是一位有成就的测量员,他遵循了当时的惯例,记录了相对精确的纬度读数,而不是经度。虽然主要队伍所走的路线是有据可查的,但这第二次穿越是未知的。为了重建威尔斯的路线,并提供一些关于树位置的可能性,需要一种更新颖的方法。为这项研究开发了专门的空间软件,比较了威尔斯精心记录的沙脊之间的高度和距离,使他的穿越重现,为这棵遥远的树的位置提供了一些确定性。

ABSTRACT The Flinders Ranges Gudgeon (Mogurnda clivicola) in South Australia, is restricted to permanent spring-fed pools of two creeks in the Northern Flinders Ranges. Consequently, the fish is classified as critically endangered. Regular monitoring of selected water chemistry and fish population characteristics has been conducted since 2018 by a “Friends of Parks” group in an ongoing project contributing to the conservation management for this endangered species. Mogurnda clivicola were abundant and healthy in Weetootla and Nepouie springs, with six or fewer fish displaying any skin lesions on each of the four sampling occasions of May and August 2019 and June and August 2020. Hence the fish populations were not adversely affected by the exceptionally low rainfall years of 2018 and 2019. Fish of less than 2 cm total length were present at each sampling time point, indicating that breeding can occur on an opportunistic basis rather than during a breeding season. Following a substantial flood during February 2020, a substantial breeding event resulted in large numbers of small fish and at Nepouie Spring. For pools that contained fish, the water quality parameters measured and their ranges were: conductivity 1141–13 800 µS/cm; dissolved oxygen concentration 1.9–12.0 mg/L; temperature 11.4–29°C; pH 7.1–8.8; [Ca++] 36–213 mg/L; [NO3-] 0.2–17.7 mg/L.
南澳大利亚的弗林德斯山脉古吉翁(Mogurnda clivicola)是位于弗林德斯山脉北部的两条小溪的永久泉水池。因此,这种鱼被列为极度濒危物种。自2018年以来,“公园之友”小组对选定的水化学和鱼类种群特征进行了定期监测,这是一个正在进行的项目,有助于对这种濒危物种的保护管理。在Weetootla和Nepouie泉中,Mogurnda clivicola数量丰富且健康,在2019年5月和8月以及2020年6月和8月的四次采样中,每一次都有6条或更少的鱼出现任何皮肤病变。因此,鱼类种群没有受到2018年和2019年异常低降雨量的不利影响。在每个采样时间点都有总长度小于2厘米的鱼,这表明繁殖可能是机会性的,而不是在繁殖季节。在2020年2月的一场大洪水之后,一场大规模的繁殖活动导致了大量的小鱼和Nepouie Spring。对于有鱼的水池,测量的水质参数及其范围为:电导率1141 ~ 13800µS/cm;溶解氧浓度1.9 ~ 12.0 mg/L;温度11.4 -29°C;pH值7.1 - -8.8;[Ca++] 36-213 mg/L;[NO3-] 0.2 ~ 17.7 mg/L。

ABSTRACT Plant communities within many of the world’s waterways are losing diversity where flows are stabilised for security and enriched from land-use intensification. Understanding the phenotypic plasticity of plant species that protect and/or store their below-ground biomass during floods may help to promote them if problematic, overabundant species – like Phragmites australis and Typha domingensis – are less plastic. To investigate mechanisms underlying the plasticity of two cosmopolitan (Phragmites, Typha) and two endemic (Cycnogeton procerum, Cyperus gymnocaulos) macrophytes in response to disturbance (fluctuating hydrological regimes) across a nutrient gradient, we analysed historical data from pond experiments with single-species pots. Our analyses showed fluctuating water levels in nutrient-enriched conditions reduced total biomass in all species, with 65% and 46% reduction in Phragmites and Typha respectively. Contrary to expectations, only Cycnogeton allocated a higher proportion of biomass to protect (root) and store (rhizome) resources in fluctuating water levels and nutrient-enriched conditions (45% versus 23% in stable regime), and was the most plastic by allocating 75% more biomass to belowground in the least favourable conditions. Our results indicate that removing impediments to stochastic flooding disturbance could benefit some endemic species while reducing the productivity of overabundant Phragmites and Typha in environments enriched by human activity.
世界上许多水道内的植物群落正在失去多样性,这些水道的流量因土地利用集约化而稳定,并因安全而丰富。了解在洪水期间保护和/或储存其地下生物量的植物物种的表型可塑性,可能有助于促进它们的发展,如果有问题,过度丰富的物种-如芦苇和叶霉-可塑性较差。为了研究两种世界性(芦苇、Typha)和两种地方性(Cycnogeton procerum、Cyperus gymnocaulos)大型植物在营养梯度扰动(波动水文制度)下的可塑性机制,我们分析了单种盆栽池塘实验的历史数据。我们的分析表明,在营养丰富的条件下,波动的水位降低了所有物种的总生物量,芦苇和Typha分别减少了65%和46%。与预期相反,只有Cycnogeton在波动的水位和营养丰富的条件下分配了更高比例的生物量来保护(根)和储存(根茎)资源(45%,而在稳定的条件下为23%),并且在最不利的条件下分配了75%以上的生物量,是最具可塑性的。我们的研究结果表明,在人类活动丰富的环境中,消除随机洪水干扰的障碍可能有利于一些特有物种,但会降低过度丰富的芦苇和台风的生产力。

ABSTRACT Gastrointestinal parasites of 106 red kangaroos, Osphranter rufus (Desmarest), are reported from Queensland, New South Wales, Victoria, South Australia, Western Australia and the Northern Territory. Previous studies have been restricted to New South Wales and Queensland. The current study increases the geographical range of studies of the parasites of O. rufus and presents evidence for regional differences in the parasite fauna. Two species of cestodes and 27 species of nematodes were encountered, with four species Cloacina hestia Beveridge, 1998, C. ixion Beveridge, 1998, Papillostrongylus barbatus Chilton, Huby-Chilton, Gasser and Beveridge, 2002 and Popovastrongylus pearsoni (Johnston & Mawson, 1940) being reported for the first time. Several species, Hypodontus macropi Mönnig, 1929, Progamotaenia festiva (Rudolphi, 1819), Labiosimplex longispicularis (Wood, 1929) , Pa. barbatus, Cloacina hydriformis Johnston & Mawson, 1938 and C. liebigi Johnston & Mawson, 1939 were widespread while others exhibited more regional distributions. Helminth communities in Queensland and New South Wales exhibited considerable similarity (89%) followed by South Australia (74%) and the south of Western Australia (71%) while the community in the north of Western Australia was the most distinctive (56% similarity).
摘要报道了来自昆士兰州、新南威尔士州、维多利亚州、南澳大利亚州、西澳大利亚州和北领地的106只红袋鼠(Osphranter rufus (Desmarest))的胃肠道寄生虫。以前的研究仅限于新南威尔士州和昆士兰州。目前的研究增加了欧鲁弗斯寄生虫研究的地理范围,并为寄生虫区系的区域差异提供了证据。共发现线虫2种,其中Cloacina hestia Beveridge, 1998, C. ixion Beveridge, 1998, Papillostrongylus barbatus Chilton, Huby-Chilton, Gasser and Beveridge, 2002, Popovastrongylus pearsoni (Johnston & Mawson, 1940)为首次报道。若干种,大腹蛇Mönnig, 1929,节目鱼(Rudolphi, 1819),长鼻唇虱(Wood, 1929),宾夕法尼亚州。barbatus, Cloacina hydriformis Johnston & Mawson, 1938和C. liebigi Johnston & Mawson, 1939广泛分布,而其他的则表现出更多的区域性分布。昆士兰州和新南威尔士州的蠕虫群落表现出相当大的相似性(89%),其次是南澳大利亚州(74%)和西澳大利亚州南部(71%),而西澳大利亚州北部的蠕虫群落最具特色(56%相似)。

ABSTRACT During the 1840s European colonists found the naturally preserved body of an Aboriginal man deep within the Naracoorte Caves of South Australia, which were to become a major tourist destination. As an example of a so-called “petrified Aborigine”, the calcified body became a key attraction for nineteenth century tourists to the region, prior to its theft and incorporation into a museum exhibit. This paper traces the history of the preserved body’s discovery to its eventual disappearance, and discusses the wide-ranging accounts of its origin and cultural significance.
19世纪40年代,欧洲殖民者在南澳大利亚的纳拉库特洞穴深处发现了一具自然保存的土著男子尸体,该洞穴后来成为一个主要的旅游目的地。作为所谓的“石化土著”的一个例子,这具钙化的尸体在19世纪被盗窃并被纳入博物馆展览之前,成为该地区游客的主要吸引力。本文追溯了这具保存完好的尸体被发现的历史,直到它最终消失,并讨论了关于它的起源和文化意义的广泛说法。

ABSTRACT The myxomycetes associated with samples of dead plant material collected from arid habitats in northeastern South Australia were investigated with the use of the moist chamber culture technique. Since myxomycetes are usually associated with relatively moist conditions, one would not anticipate them to be very common in arid areas. However, 69% of the cultures prepared yielded some evidence (either plasmodia or fruiting bodies) of myxomycetes. A total of 26 species of myxomycetes representing 10 different genera were recorded, including one species (Licea succulenticola) not previously reported from Australia and 11 others that appear to represent new records for South Australia. The distribution of the myxomycetes associated with substrates in arid areas of northeastern South Australia is discussed.
摘要采用湿室培养技术对南澳大利亚东北部干旱生境植物死亡材料中黏菌进行了研究。由于黏菌通常与相对潮湿的环境有关,人们不会预料到它们在干旱地区很常见。然而,69%的培养物产生了黏菌的证据(无论是疟原虫还是子实体)。共记录黏菌10属26种,其中1种(Licea succulenticola)为澳大利亚未报道种,11种为南澳大利亚新记录种。本文讨论了南澳大利亚东北部干旱地区黏菌的分布。
