A critical review of Antarctic Conoidea (Neogastropoda)

ABSTRACT

The Antarctic Conoidean fauna is critically reviewed based on published data and specimens in the collections of the USNM, IORAS and MNHN. Forty-two species and subspecies of the superfamily Conoidea are recorded as occurring within the Antarctic Convergence (excluding the fauna of the Kerguelen Islands) and are attributed to 14 genera and seven families. These include the new taxa: Antarctospira n. gen. (type species—Leucosyrinx badenpowelli Dell, 1990); Drilliola antarctica n. sp.; Pleurotomella (Pleutoromella) tippetti n. sp.; Pleurotomella (Anomalotomella) petiti n. sp.; Xanthodaphne pastorinoi n. sp. Aforia watsoni is introduced as a new name for Pleurotoma (Surcula) lepta Watson, 1881, non Pleurotoma lepta Edwards, 1861. A lectotype is designated for Conorbella antarctica (Strebel, 1908). New combinations are also proposed. Antarctospira badenpowelli (Dell, 1990), n. comb. (previously assigned to Leucosyrinx); Antarctospira principalis (Thiele, 1912), n. comb. (previously assigned to Typhlomangelia); Antarctospira mawsoni (Powell, 1958), n. comb. (previously assigned to Leucosyrinx); Typhlodaphne paratenoceras (Powell, 1951), n. comb. (previously assigned to Leucosyrinx); Belalora weirichi (Engl, 2008), n. comb. (previously assigned to Oenopota); Pleurotomella (Anomalotomella) innocentia (Dell, 1990), n. comb. (previously assigned to Typhlodaphne); Pleurotomella (Anomalotomella) nipri (Numanami, 1996), n. comb. (previously assigned to Typhlodaphne); Xanthodaphne raineri (Engl, 2008), n. comb. (previously assigned to Pleurotomella); Aforia hedleyi (Dell, 1990), n. comb. (previously assigned to Pontiothauma). The majority of Antarctic conoidean taxa have hypodermic marginal teeth. Although there is a similar relative abundance of conoideans in Antarctic waters to that seen in other well-studied faunas, the low number of conoideans is indicative of the general impoverishment of the gastropod fauna in the region. Fourteen percent (2 of 14) of conoidean genera that occur within the Antarctic Convergence are endemic to Antarctic waters, as are 82% (34 of 42) of the species. Most taxa have very broad bathymetric ranges, some extending from bathyal to hadal depths. The greatest species diversity was at bathyal depths.     

厦门市道路绿化基本树种病虫害名录的更新调查与分析

通过对厦门市道路绿化基本树种病虫害名录的更新调查显示,从1986年至2006年的20年间,厦门市道路绿化基本树种更新17种,新发现病虫害12种;本文还确立了病虫危害程度的划分标准,重新调查并确定了各种病虫害的为害程度等级,明确了白囊蓑蛾等26种病虫害为重要防治对象。     

A new replacement name for Tropidocephala speciosa Ding, 2006 (Hemiptera,Fulgoromorpha, Delphacidae)

A new replacement name is proposed for the species Tropidocephala speciosa Ding, 2006 (Hemiptera: Fulgoromorpha: Delphacidae: Tropidocephalini), preoccupied by Tropidocephala speciosa (Bierman, 1908): Tropidocephala dingi Sun, Yang & Chen, nom. n. = Tropidocephala speciosa Ding, 2006. The photographs and illustrations of this species are also provided.     

Phylogenetic relationships of Old World Brassicaceae from Iran based on nuclear ribosomal DNA sequences

Phylogenetic analysis of 155 nuclear rDNA ITS sequences among them 19 Iranian endemic genera were used to elucidate phylogenetic relationships of Old World Brassicaceae from Iran in the context of the most recent tribal system suggested by Al-Shehbaz et al. [Al-Shehbaz, I.A., Beilstein, M.A, Kellogg, E.A., 2006. Systematics and phylogeny of the Brassicaceae (Cruciferae): an overview. Plant Syst. Evol. 259, 89–120]. Iranian endemic taxa are assigned to 16 clades, 15 of these correspond to recognized tribes. Our data support the recent tribal recognition of Calepina and relatives and further indicate that the Orychophragmus clade (with Conringia planisiliqua and Orychophragmus) may be recognized as a new tribe. Our data also support the inclusion of 13 genera not previously studied, or with unresolved positions in previous phylogenetic analyses in 10 tribes with the tribal assignment given in parentheses: Acanthocardamum (Aethionemeae), Alyssopsis (Camelineae), Anastatica (Malcolmieae), Asperuginoides (Cochlearieae), Camelinopsis (Thlaspideae), Didymophysa (Thlaspideae), Dielsiocharisi (Camelineae), Lachnoloma (Anchonieae), Micrantha (Anchonieae), Noccidium (Camelineae), Octoceras (Euclidieae), Pseudofortuynia (Sisymbrieae) and Streptoloma (Euclidieae). ITS data and morphological characters further indicate that the remaining five genera, i.e., Acanthocardamum, Olimarabidopsis, Brossardia, Noccidium and Zuvanda may be subsumed under Aethionema, Alyssopsis, Noccaea, Capsella and Conringia, respectively. Alyssum, Chorispora, Fibigia and Goldbachia are paraphyletic and Conringia, Malcolmia, Matthiola are polyphyletic taxa.     

罂粟正名考

十世纪前罂粟传入中国后,随着岁月的迁移出现了大量的中文名称。其中不少的名称曾作为正名载于古籍。本文讨论了古代罂粟用名的混乱和正名的选用。     

中国树甲族一新纪录属二新种及二新名(鞘翅目,拟步甲科)

Brain activity in an awake chimpanzee in response to the sound of her own name

The brain activity of a fully awake chimpanzee being presented with her name was investigated. Event-related potentials (ERPs) were measured for each of the following auditory stimuli: the vocal sound of the subject''s own name (SON), the vocal sound of a familiar name of another group member, the vocal sound of an unfamiliar name and a non-vocal sound. Some differences in ERP waveforms were detected between kinds of stimuli at latencies at which P3 and Nc components are typically observed in humans. Following stimulus onset, an Nc-like negative shift at approximately 500 ms latency was observed, particularly in response to SON. Such specific ERP patterns suggest that the chimpanzee processes her name differently from other sounds.
