Benthic samples were collected during two expeditions near the Antarctic Peninsula and in the South-Eastern Weddell Sea. During these studies, a new species of Ampharetidae Malmgren, 1867, Anobothrus konstantini Säring & Bick sp. nov., was found. Here we present a detailed description of this species. We used the traditional light microscope and scanning electron microscope (SEM) to identify and describe the diagnostic characters: a circular glandular band on segment 6; an elongate ridge between the notopodia on segment 12 and modified notochaetae on this segment; 16 thoracic, two intermediate and ten abdominal segments. For the first time, micro-computed tomography (micro-CT) was used for a species description of Anobothrus. Micro-CT provided information on the shape of the prostomium (Ampharete-type) and the arrangement of branchiae (four pairs in two rows, without a gap). In addition, we provide quantitative information on the environmental niche based on sediment parameters (chlorophyll a content, organic matter content, chloroplast equivalent, grain size) for the new Anobothrus species, relevant for, e.g., species distribution modelling. Finally, an identification key for all Anobothrus species is provided.

Thanks to newly collected material from the Terra Nova Bay area (Ross Sea, Antarctica), we discuss the taxonomy of the ampharetid genera Amage Malmgren, 1866 and Amythas Benham, 1921. A new species of Amage, A. giacomobovei sp. nov., is described based on morpho-anatomical data. This is the second new species described from an area which appears to be rich in ampharetids, a coastal embayment at ~500 m depth near the Italian “Mario Zucchelli” research station. The new species is characterized by having 16 abdominal uncinigers and four pairs of branchiae that readily distinguish it from its congeners. Tubes of A. giacomobovei sp. nov. are also characteristic in showing a large amount of embedded sponge spicules, suggesting a possible close association to spicule mats. Based on the amended diagnoses of the two genera, Amage septemdecima Schüller & Jirkov, 2013 is transferred to the genus Amythas. Finally, to simplify the task of ampharetid genera recognition for untrained people, we provide a dichotomic key for ampharetid genera found in Antarctica and a checklist of species occurring in Terra Nova Bay.

The nesting biology of the potter wasp Pachymenes ghilianii (Spinola) (Hymenoptera: Vespidae: Eumeninae) is described based on observations made in the Cerro Turega Hydric Reserve, Penonome, Panama. The collection of building material, the architecture of the nest, the process of building a cell and cell provision with geometrid larvae (Lepidoptera: Geometridae), and the emergence time of the adults are recorded.
Der Zwerg-Rohrkolben (Typha minima Funck ex Hoppe) ist eine charakteristische Pionierpflanze von alpinen Wildflusslandschaften. Seit den siebziger Jahren ist diese Kennart jedoch in Deutschland vollständig und in Österreich nahezu ausgestorben. Die anhaltenden Populationsrückgänge der Art sind wahrscheinlich das Ergebnis der weitverbreiteten Flussregulierung und des Kraftwerksbaus in Kombination mit den sehr speziellen Standortsansprüchen der Art. Dank den Anstrengungen von Wiederansiedlungsprogrammen befindet sich T. minima wieder an der Oberen Drau in Österreich. In dieser Publikation wird über die Keimung, das Wachstum, die Reproduktion und die Umweltpräferenzen von T. minima berichtet.
Die Keimungsexperimente von 2014 zeigten eine sehr niedrige mittlere Keimungsrate von 15,6% bei einem Schwankungsbereich von 0–90 %. Die Keimungsraten stiegen mit höheren Temperaturen, erhöhter Saatgutreife und kürzeren Saatgutlagerungszeiten. Nach der Saatgutlagerung von 480 Stunden wurde keine Keimung mehr beobachtet.
Beim FFH-Monitoring 2014 an der Oberen Drau wurden Zwerg-Rohrkolben-Keimlinge (Höhe < 5 cm) generell nur selten gefunden. Die vegetative Jungphase (Höhe > 15 cm, ausschließlich sterile Triebe) wies zumeist den höchsten Flächenanteil im Mittel von 62% auf. Typha minima bildete bis zu einem Alter von ca. 3 Jahren ausschließlich sterile Triebe aus. Ab einem Alter von ca. 9 Jahren wurden auch fertile Triebe mit Blütenständen ausgebildet, wobei deren Anzahl mit zunehmendem Alter sich tendenziell erhöhte. Die Analyse der Standortsfaktoren zeigte, dass T. minima auf eine hohe Bodenfeuchte im Mittel von 39 Vol-% angewiesen ist. Darüber hinaus war der Faktor Beschattung entscheidend. Erst ab einem Beschattungsgrad von 50% durch Weidengebüsche war eine Abnahme der Triebdichte von T. minima zu verzeichnen. Wir schließen daraus, dass T. minima-Populationen während der Keimungsphase extrem empfindlich sind und dass massive Habitatverluste überwiegend das Ergebnis der Flussregulation und der reduzierten Morphodynamik sind, die normalerweise geeignete offene Siedlungsräume für die Keimung des Zwerg-Rohrkolbens schaffen würde.
Three new species of the genus Carychium O.F. Müller, 1773, Carychium hardiei Jochum & Weigand, sp. n., Carychium belizeense Jochum & Weigand, sp. n. and Carychium zarzaae Jochum & Weigand, sp. n. are described from the Southeastern United States, Belize and Panama, respectively. In two consecutive molecular phylogenetic studies of worldwide members of Carychiidae, the North and Central American morphospecies Carychium mexicanum Pilsbry, 1891 and Carychium costaricanum E. von Martens, 1898 were found to consist of several evolutionary lineages. Although the related lineages were found to be molecularly distinct from the two nominal species, the consequential morphological and taxonomic assessment of these lineages is still lacking. In the present paper, the shells of these uncovered Carychium lineages are assessed by comparing them with those of related species, using computer tomography for the first time for this genus. The interior diagnostic characters are emphasized, such as columellar configuration in conjunction with the columellar lamella and their relationship in context of the entire shell. These taxa are morphologically described and formally assigned their own names.
Trogulus banaticus Avram, 1971 is characterised and recorded as new for Slovenia. This species was previously mistaken for T. coriziformis C. L. Koch, 1839 and T. graecus Dahl, 1903 which were later rejected from the Slovenian fauna. T. banaticus is compared with the similar, and partly sympatric, T. tingiformis C. L. Koch, 1847 with which it has often been confused. A table of distinguishing characters for both species is provided, and the ecology of T. banaticus and its general distribution are discussed.
Spatial and temporal structure of the spider community in the clay semi-desert of western Kazakhstan
(2011)
The spatial and temporal structure of spider communities was studied in the clay semi-desert of the north-western Caspian Lowland, western Kazakhstan (49°23' N, 46°47' E). The soils and vegetation are complex, being composed of a mosaic of desert and steppe plant communities. Besides the native associations, there are plantations of different tree species. The ground-dwelling spider assemblages in the native habitats are the most diverse. The number of species inhabiting forest plantations is three times as small. Gnaphosidae is the leading family in the ground layer. They show high abundance and diversity levels during the whole season. Thomisidae, Lycosidae, Philodromidae, and Salticidae are abundant as well. The species diversity of herbage-dwelling spiders in different open native habitats is very similar. The spectrum of dominant families (Thomisidae, Oxyopidae, Araneidae, and Salticidae) and the seasonal dynamics of their ratio in desert and steppe associations have much in common. Spider assemblages of native and artificial habitats are characterised by change from multispecies polydominant spring-summer communities to impoverished imbalanced autumn ones. Seasonal changes in the species structure of mature spider groupings in native habitats are well pronounced, while the impact of seasonal conditions is even stronger than between-habitat differences. Complexes of typical species with different levels of habitat preference are revealed.
