ABSTRACT Aplacophorans are vermiform marine molluscs found in benthic habitats worldwide. However, there is an extreme lack of knowledge about their true diversity. There are around 440 described species, but the true number is estimated to be at least tenfold higher. Identifying most solenogaster aplacophorans to the species, genus and sometimes even family level requires histology so that internal anatomical structures, such as the radula, foregut glands, and reproductive organs can be characterised. The aplacophoran faunas of many regions have barely been studied or have not been studied at all. An example is the waters surrounding New Zealand where only three species have been described to date. To advance the understanding of the biodiversity of Aplacophora, we describe three new species of solenogaster aplacophorans from New Zealand, all of which belong to the family Proneomeniidae Simroth, 1893: Dorymenia tanifa n. sp., Dorymenia ancora n. sp. and Dorymenia lucida n. sp. New data on Dorymenia quincarinata (Ponder, 1970) are also included and a comparison of all Dorymenia species is described in detail. In addition, DNA barcodes were obtained from D. lucida n. sp. and D. quincarinata, which will be useful for future specimen identification by non-experts and future studies on aplacophoran evolution.
摘要Aplacphorans是一种在世界各地海底栖息地发现的蠕虫状海洋软体动物。然而,人们对它们真正的多样性知之甚少。描述的物种约有440种,但真实数量估计至少高出十倍。从物种、属,有时甚至科的层面上识别大多数Solenoaster aplacophorans需要组织学,以便能够表征内部解剖结构,如舌苔、前肠腺和生殖器官。许多地区的aplacophoran动物群几乎没有被研究或根本没有被研究。一个例子是新西兰周围的水域,迄今为止,那里只描述了三种物种。为了进一步了解Aplacophora的生物多样性,我们描述了来自新西兰的三个新的Solenomaster aplacophorans物种,它们都属于Proneomenidae Simroth家族,1893年:Dorymenia tanifa n.sp.、Dorymeni ancora n.sp.和Dorymeniia lucida n.sp。还包括了关于金花Dorymenia quincarinata的新数据(Ponder,1970),并详细描述了所有Dorymonia物种的比较。此外,还从D.lucida n.sp.和D.quincarinata中获得了DNA条形码,这将有助于非专家未来的标本鉴定和无孔虫进化的研究。

ABSTRACT Kerkia is a snail genus inhabiting mainly subterranean waters. Live specimens of Kerkia were collected in the West Balkans. Mitochondrial cytochrome c oxidase subunit I and nuclear histone H3 were sequenced. Populations of Kerkia molecularly represented 10 mOTUs, each deserving a species rank. Apart from known species, five new species are described. The interspecies differences in shell morphology were slight and thus morphology did not reflect the evident molecular differences. All available information about the penes and female reproductive organs are summarised and their limited usefulness in species-level taxonomy is discussed. Kerkia seems to represent another example of morphostatic evolution, a result of non-adaptive radiation marked by the rapid proliferation of sibling species, whose ecology most probably remains the same. In Kerkia, intrapopulation genetic diversity does not (or almost does not) exist, and the same is true for intraspecies variation. At the same time, there is a high level of molecular difference between the species. Despite potential means for range expansion of the stygobiont fauna provided by interstitial habitats, which reduce the levels of endemism in some stygobiont gastropod species, the species of stygobiont Kerkia are restricted to small geographic areas.

螺属是一种主要生活在地下水中的蜗牛属。Kerkia的活标本是在西巴尔干地区收集的。线粒体细胞色素c氧化酶亚基I和核组蛋白H3测序。Kerkia的种群在分子上代表10个motu,每个motu都有一个物种等级。除已知种外,还发现了五种新种。种间壳形态差异不大,不能反映明显的分子差异。本文总结了所有关于阴茎和雌性生殖器官的信息,并讨论了它们在种级分类中的有限用处。Kerkia似乎代表了形态静止进化的另一个例子,这是一种非适应性辐射的结果,其特征是兄弟物种的快速增殖,其生态很可能保持不变。在Kerkia中,种群内遗传多样性不存在(或几乎不存在),种内变异也是如此。与此同时,物种之间存在着高度的分子差异。尽管间隙生境提供了潜在的手段来扩大茎吸虫动物群的范围,从而降低了某些腹足类茎吸虫物种的地方性水平,但茎吸虫Kerkia的物种仅限于小的地理区域。LSID: urn: LSID zoobank.org:酒吧:f710d90a c64 -美国陆军和空军交易服务处的- 4427 - 4 - 5 - ade89eeaabc

ABSTRACT For over 50 years Winston Ponder has been at the forefront of molluscan research. Young Winston collected land snails in the environs of Lower Hutt, New Zealand and marine species at Waikanae Beach northwest of Wellington. He attended Victoria University in Wellington in 1959 but moved to Auckland University in 1960 to study under Professor John E. Morton, with whom he completed his B.Sc. in 1963 (Galeommatoidea), his M.Sc. with 1st Class Honours in 1965 (Rissoidae), and his Ph.D. in 1968 (Neogastropoda). Winston was appointed Curator of Marine Invertebrates at the Dominion Museum in 1967. However, he soon moved to Australia after accepting the position of Curator of Molluscs at the Australian Museum in 1968. He would spend the next 37 years there. Winston has published in almost 50 different scientific journals and numerous edited books and volumes. He has collaborated with almost 100 different co-authors from around the world and has addressed multiple taxa and questions across the phylum. He has been a strong advocate for Australasian malacology. His advocacy has also included a robust outreach to students. However, his advancement of Australasian malacology was not done to the exclusion of the global role and needs of the discipline.
摘要50多年来,Winston Ponder一直走在软体动物研究的前沿。年轻的温斯顿在新西兰下赫特附近采集陆地蜗牛,在惠灵顿西北部的怀卡纳海滩采集海洋物种。1959年,他就读于惠灵顿维多利亚大学,1960年转到奥克兰大学,师从约翰·E·莫顿教授。1963年,他与莫顿教授一起完成了理学学士学位(Galommatoidea),1965年,他获得了一级荣誉理学硕士学位(Rissodeae),1968年,他又获得了博士学位(新腹足目)。1967年,温斯顿被任命为多米尼克博物馆海洋无脊椎动物馆长。然而,在1968年接受澳大利亚博物馆软体动物馆长的职位后,他很快就搬到了澳大利亚。他将在那里度过接下来的37年。Winston在近50种不同的科学期刊上发表了文章,并编辑了许多书籍和卷本。他与来自世界各地的近100位不同的合著者合作,解决了整个门的多个分类群和问题。他一直是澳大拉西亚软化学的有力倡导者。他的宣传活动还包括对学生的大力宣传。然而,他对澳大拉西亚软化学的发展并没有排除该学科的全球作用和需求。

ABSTRACT Gastropoda is probably the best-known taxon which uses acid glands as an antifouling strategy and as defence against putative predators. Here, defensive acid-secreting cell types in two taxa of Caeonogastropoda, Cypraeidae and Ovulidae, were investigated. This study confirms the presence of acid epithelial glands in several members of the Cypraeidae, with the glands of the Cypraeidae species Naria nebrites and Mauritia mauritiana being newly described here. We also present results for the first time on a member of the family Ovulidae, Simnia spelta. All investigated species exhibited an outer epidermis with glandular acid cells of columnar shape with large clear, colourless vacuoles, thus resembling the previously described species of these taxa. None of the investigated cypraeid and ovulid species studied here exhibited subepidermal acid glands in the mantle, which are typical for the Velutinoidea. The phylogenetic value of these findings is discussed in relation to a recently published phylogeny on Caenogastropoda comprising all families of Cypraeoidea and Velutinoidea.
腹足动物可能是最著名的一类动物,它们使用酸腺作为防污策略和防御潜在的捕食者。本文研究了海腹足动物Cypraeidae和Ovulidae两个分类群的防御性分泌酸细胞类型。本研究证实了几种鲤科成员中酸性上皮腺的存在,其中新描述了鲤科物种Naria nebrites和Mauritia mauritiana的腺体。我们也首次报道了菊科的一个成员,Simnia spelta。所有被调查的物种都表现出具有柱状腺酸细胞的外表皮和大的透明无色液泡,因此与这些分类群中先前描述的物种相似。本研究所调查的苏科和卵形科均未在地幔中显示典型的皮下酸腺。这些发现的系统发育价值与最近发表的一篇关于鱼腹足动物的系统发育的文章有关,该系统发育包括所有科的cypraeo总科和velutino总科。

ABSTRACT The aim of this work is to investigate the effects of environmental stressors on male reproductive biomarkers in sentinel species of bivalves inhabiting Annaba estuaries, considered to be reservoirs receiving industrial, agricultural, and domestic discharges. Male Mytilus galloprovincialis were collected in four seasons from a non-polluted site (S1) and two other locations receiving untreated sewage (S2) and a mixture of contaminants (S3). Testicular sperm concentration, motility, velocity, the amplitude of lateral head displacement (ALH), the beat cross frequency (BCF), spermatozoan DNA fragmentation, and histological profiles were evaluated. Individuals from S2 and S3 have diminished sperm concentration, motility, velocity, ALH and BCF, along with a significantly increased spermatozoan DNA fragmentation that was much higher in S3. Testicular tissues demonstrated histo-pathological alterations in mussels subjected to anthropogenic activities during the four seasons. In conclusion, reproductive biomarkers of male mussels were both spatially and temporally variable, which is probably correlated to pollution types and the changing seasonal stressors.
摘要本工作的目的是研究环境压力对居住在Annaba河口的双壳类前哨物种雄性生殖生物标志物的影响,Annaba河口被认为是接收工业、农业和家庭排放的水库。从一个未受污染的地点(S1)和另外两个接受未经处理的污水(S2)和污染物混合物(S3)的地点,分四个季节收集雄性加洛氏Mytilus galloprovincialis。评估睾丸精子浓度、活力、速度、头部侧向位移幅度(ALH)、搏动交叉频率(BCF)、精子DNA断裂和组织学特征。S2和S3的个体精子浓度、活力、速度、ALH和BCF降低,精子DNA片段显著增加,S3的精子DNA片段要高得多。在四个季节受到人为活动影响的贻贝中,睾丸组织表现出组织病理学改变。总之,雄性贻贝的生殖生物标志物在空间和时间上都是可变的,这可能与污染类型和季节性压力的变化有关。

ABSTRACT Inle Lake in central Myanmar is one of the hotspots of freshwater biodiversity in Southeast Asia. A small malacological collection from the lake made by Thomas Nelson Annandale and discovered at the Kyoto University Museum, Japan was examined here. In the collection comprised of thirty specimens, nine species in seven families were identified. The collection also included four species and one subspecies which were newly described by Annandale. Two subspecies, Hydrobioides nassa lacustris Annandale, 1918 and H. n. rivulicola Annandale, 1918, were identified in a single lot. The correspondence of the shell morphology of Lamellidens ferrugineus (Annandale, 1918) between the present study and the original description indicates that the specimen is a paratype of the species. The rediscovered collection provides us with insights into the species definition of Annandale and the molluscan diversity of the lake prior to recent environmental changes.
摘要缅甸中部的因乐湖是东南亚淡水生物多样性的热点之一。托马斯·纳尔逊·安南代尔在日本京都大学博物馆发现的一件来自湖中的小型软体动物学藏品在这里被检查。在由30个标本组成的标本集中,鉴定出7科9种。该系列还包括Annandale新描述的四个物种和一个亚种。在一个批次中鉴定出两个亚种,即Hydrobioides nassa lacustris Annandale,1918和H.n.rivulicola Annandale。铁纹Lamellidens ferrogineus(Annandale,1918)的外壳形态在本研究和原始描述之间的对应关系表明,该标本是该物种的副型。重新发现的藏品为我们提供了对安纳代尔的物种定义以及在最近的环境变化之前该湖软体动物多样性的见解。

ABSTRACT This study was conducted between February and May 2019 on mature Cornu aspersum in the Black Sea region, Turkey to investigate the effects of different hibernation situations on reproductive responses. Three snail groups were studied: NH (natural hibernation), ASH (artificial short hibernation) and ALH (artificial long hibernation). NH showed inactive behaviour and had no reproductive activity while ASH and ALH performed intensive reproduction. During the experiment, the mean spawning rate (SpR), egg number (EgN), hatching rate (HR) and offspring number (OfN) were 20.50 ± 1.69%, 100.10 ± 5.22, 85.63 ± 2.36 and 80.69 ± 5.44 in the ASH group; 23.43 ± 3.36%, 122.33 ± 7.62, 61.55 ± 10.76 and 70.26 ± 11.60 in the ALH group, respectively. In conclusion, the high temperatures in the winter months of 2019 may have caused NH snails to become reproductively inactive, or it could simply be a consequence of their life-history strategy.

本研究于2019年2月至5月在土耳其黑海地区对成熟的长尾角贝(Cornu aspersum)进行了研究,探讨了不同冬眠环境对其繁殖反应的影响。研究了自然冬眠组(NH)、人工短冬眠组(ASH)和人工长冬眠组(ALH)。NH表现为不活跃行为,无繁殖活动,而ASH和ALH则表现为密集繁殖。试验期间,ASH组的平均产卵率(SpR)、卵数(EgN)、孵化率(HR)和子代数(OfN)分别为20.50±1.69%、100.10±5.22、85.63±2.36和80.69±5.44;ALH组分别为23.43±3.36%、122.33±7.62、61.55±10.76、70.26±11.60。总之,2019年冬季的高温可能导致NH蜗牛变得繁殖不活跃,或者这可能只是它们生活史策略的结果。ASH组和ALH组的蜗牛代表了在繁殖力和生存之间的资源分配权衡,以将遗传信息传递给下一代。该研究有助于更好地了解蜗牛在不同冬眠条件下的生殖生理和行为反应。

NH showed inactive behaviour and had no reproductive activity while ASH and ALH performed intensive reproduction. During the experiment, the mean spawning rate (SpR), egg number (EgN), hatching rate (HR) and offspring number (OfN) were 20.50 ± 1.69%, 100.10 ± 5.22, 85.63 ± 2.36 and 80.69 ± 5.44 in the ASH group; 23.43 ± 3.36%, 122.33 ± 7.62, 61.55 ± 10.76 and 70.26 ± 11.60 in the ALH group, respectively. In conclusion, the high temperatures in the winter months of 2019 may have caused NH snails to become reproductively inactive, or it could simply be a consequence of their life-history strategy.

ABSTRACT Sepiolidae (Cephalopoda: Sepiolida) are growing in popularity as model organisms, not least because of their well-studied symbiotic relationship with light producing bacteria. Their easy maintenance and cultivation requirements in captivity have further facilitated their use in a wide range of developmental, anatomical, neurophysiological, behavioural and genetic studies, exhibiting promising opportunities for these cephalopods in research. Considering the rising interest in sepiolids, a detailed overview of their behavioural ecology is necessary to understand their evolution and conservation, as well as to aid establishment of good welfare practice when held in captivity. To date, not all aspects of the sepiolid ecology have been investigated in detail, and our current knowledge of their behavioural ecology is, for the most part, restricted to descriptions from less than 10 of the approximately 80 species, occasionally resulting in a generalisation of specific observations across species, genera, or even subfamilies. This review summarises current knowledge on sepiolid behavioural ecology and life history, including discussions on their habitat, life span, activity patterns, hunting and feeding behaviour, anti-predator behaviour, burying behaviour, and reproductive behaviour. Moreover, future directions as well as areas of interest for upcoming research studies are highlighted.
摘要海泡子科(头足目:海泡子目)作为模式生物越来越受欢迎,尤其是因为它们与产光细菌的共生关系得到了充分的研究。它们在圈养条件下易于维护和培养,进一步促进了它们在广泛的发育、解剖学、神经生理学、行为和遗传学研究中的应用,为这些头足类动物的研究提供了有希望的机会。考虑到人们对海泡石的兴趣越来越大,有必要详细了解它们的行为生态学,以了解它们的进化和保护,并帮助建立圈养时的良好福利做法。到目前为止,并不是海泡石生态学的所有方面都得到了详细的研究,我们目前对其行为生态学的了解在很大程度上仅限于对大约80个物种中不到10个物种的描述,偶尔会导致对物种、属甚至亚科的具体观察结果的概括。这篇综述总结了目前关于褐藻行为生态学和生活史的知识,包括对其栖息地、寿命、活动模式、狩猎和觅食行为、反捕食者行为、埋葬行为和繁殖行为的讨论。此外,还强调了未来的方向以及即将进行的研究的兴趣领域。

ABSTRACT A series of deep-sea expeditions in southeastern Australia has produced a considerable amount of conoidean (Gastropoda: Neogastropoda) material suitable for molecular and morpho-anatomical study. Previous and ongoing studies have revealed the Raphitomidae to be particularly diverse in the deep waters of this region. Here, we continue our conoidean investigation, focussing on the genera Comispira (Cochlespiridae) and Leucosyrinx (Pseudomelatomidae). We subjected two cytochrome oxidase subunit DNA sequence datasets of Conoidea to Automatic Barcode Gap Discovery (ABGD), which recognised a total of 18 primary species hypotheses (PSHs) among our target genera as well as from the cochlespirid genera Sibogasyrinx and Aforia. Following additional evaluation of shell and radular features, as well as examination of geographic and bathymetric ranges (conducted for PSHs of Australian waters), eight of these PSHs were converted to secondary species hypotheses (SSHs). Of these, three SSHs (one Comispira species, two Leucosyrinx spp.) were recognised as new to science and their full systematic descriptions are provided herein. While we discuss the relatively low diversity of Cochlespiridae compared to most conoidean families, two Comispira species and one species of Aforia are here recorded for the first time from Australian waters. http://zoobank.org/urn:lsid:zoobank.org:pub:0D342202-1901-4379-9EA8-6E7C1A4AAD7B
摘要在澳大利亚东南部进行的一系列深海探险已经产生了大量适合分子和形态解剖学研究的锥总目(腹足目:新腹足目)材料。先前和正在进行的研究表明,在该地区的深水中,Raphitoidae特别多样化。在这里,我们继续我们的锥总科调查,重点是Comispira属(Cochlespiridae)和Leucosyrinx属(Pseudomelatoidae)。我们对锥总科的两个细胞色素氧化酶亚基DNA序列数据集进行了自动条形码缺口发现(ABGD),该发现识别了我们的目标属以及胭脂虫属Sibogasyrinx和Aforia中总共18个初级物种假说(PSH)。在对贝壳和雷达特征进行额外评估,以及对地理和水深范围进行检查(针对澳大利亚水域的PSH进行)后,其中8个PSH被转换为次级物种假说(SSH)。其中,三个SSH(一个Comipira物种,两个Leucosyrinx spp.)被认为是科学上的新物种,本文提供了它们的完整系统描述。虽然我们讨论了与大多数锥总科相比,Cochlspiridae的多样性相对较低,但这里首次从澳大利亚水域记录到了两个Comspira物种和一个Aforia物种。http://zoobank.org/urn:lsid:zoobank.org:pub:0D342202-1901-4379年
