description: Pyrenula gigaspora Soto-Medina, Aptroot & Lücking, sp. nov.
(Fig. 3)
A new Pyrenula similar to P. montocensis Lücking, but differing by its larger ascospores of 125-140 ×40-45 µm.
HOLOTYPE. — Colombia. Valle del Cauca, Municipio Bugalagrande, Hacienda la Venta, 4°11’56.2”N, 76°03’56.2”W, 1166 m, bosque seco tropical, 23-27.IX.2020, Soto Medina s.n. (holo-, TULV).
ETYMOLOGY. — The epithet refers to the giant ascospores.
ECOLOGY. — The species grows on branches in the interior of the tropical dry forest.
CHEMISTRY. — Thallus UV–, K–, C–; medulla C–, K–, KC–.
MYCOBANK. — MB 849071.
DESCRIPTION
Thallus crustose, corticate, olive-green, with abundant spots with crystals (pseudocyphellae). Photobiont of a species of Trentepohlia. Perithecia solitary, dispersed, hemispherical but mostly immersed and only upper portion erumpent from the thallus, basally and in part laterally covered by thallus, c. 0.9-2 mm diam. Ostioles apical, flat, black. Hamathecium not inspersed. Asci 2-spored. Ascospores becoming dark brown, 3-septate, narrowly ellipsoid to almost fusiform, 125-140× 40-45 µm, ends rounded, lumina more or less diamond-shaped, separated from the walls by a thickened endospore layer. Pycnidia not observed.
NOTES
This new species is characterized by unusually large ascospores occurring singly in the asci. Thus far, the largest 3-septate ascospores in the genus known were those of Pyrenula montocensis Lücking, which are up to 90 ×30 µm in size, and P. subpraelucida Müll. Arg., which are up to 75 ×30 µm in size and with small terminal lumina. Some Pyrenula species with muriform ascospores have much larger ascospores, in the order of 200 µm. The latter also differs in thallus morphology, whereas P.montocensis agrees with the new species in the pseudocyphellate thallus and both species are undoubtedly closely related. This thallus morphology is also found in the common P. quassiicola Fée which, however, has much smaller ascospores (25-40 × 8-15 µm) (Aptroot et al. 2008). The new species would key out in the recent world key to the family (Aptroot 2021) in couplet B72 with: ascospores 125-140×40-45 µm.

description: This paper is a preliminary report on the structure of relative clauses in Tsez, one of the Tsezic languages within the Daghestanian subgroupof the Nakh-Daghestan language family. The major strategy for forming relative clauses in Tsez is a prenominal participial strategy, and this is the topic of sections 1––5. In addition, Tsez can construct relative clauses using a correlative strategy, and relative clauses of this kind are discussed in section 6.

Räumliche Zusammenhänge zwischen Keimlingen und Samenbäumen an drei Standorten im Raum Zürich.: Analyse zur Samenverbreitung und Mikrohabitat einheimischer Baumarten.
Creators: name: Gäumann, Stefan
Publisher: name: ETH Zurich

description: Die generative Baumverjüngung ist ein wichtiger Prozess der natürlichen Walddynamik. Dabei
ist die Etablierung der Keimlinge aus Samen ein komplexer Vorgang, welcher von vielen Faktoren abhängt und bei einem Grossteil der Samen nicht erfolgreich endet. Für eine erfolgreiche
Etablierung müssen keimfähige Samen an Stellen vorhanden sein, welche eine Keimung zulassen. Dabei spielen die räumliche Verteilung der Samenbäume als Samenproduzenten und
die Eigenschaften des Keimsubstrats als Mikrohabitat wichtige Rollen.
Um die räumlichen Zusammenhänge der Samenbäume und Keimlinge zu untersuchen, wurden Samenbäume in verschiedenen Waldbeständen an drei Standorten im Raum Zürich kartiert. In Kombination mit Keimlings- und Mikrohabitatsaufnahmen einer vorhergehenden Arbeit
an denselben Standorten konnten die Zusammenhänge analysiert werden. Zusätzlich konnte
mit den vorhandenen Daten das Keimbeet und die Wirkung des Mikrohabitats auf die Anzahl
der Keimlinge untersucht werden.
Von den 20 vorkommenden Baumarten im Gebiet wurde der Bergahorn (Acer pseudoplatanus), die Buche (Fagus sylvatica), die Esche (Fraxinus excelsior), die Fichte (Picea abies), die
Hagebuche (Carpinus betulus) und die Tanne (Abies alba) genauer untersucht. Der räumliche
Zusammenhang von Samenbäumen und Keimlingen wurde anhand von erstellten Samenbaumkarten, gemessenen Distanzen von Samenbäumen zu Keimlingen und der Wirkung der
Basalfläche auf die Anzahl der Keimlinge untersucht. Anhand der Grösse eines Samenbaumes und der Distanz zu den Keimlingen wurde ein Samendichte-Index berechnet, welcher als
erklärende Variable zur Vorhersage der Anzahl Keimlinge in generalisierten linearen gemischten Modellen (GLMM) verwendet wurde. Das Keimbeet der Baumarten wurde mit einer Hauptkomponentenanalyse untersucht und die Wirkung des Mikrohabitats auf die Keimlinge durch
die Integration in den GLMMs analysiert.
Die gefundenen Resultate zeigen, dass die Baumarten des Bestandes mit den Baumarten der
Keimlinge grösstenteils übereinstimmen, obwohl es zahlenmässig starke Unterschiede zwischen den Baumarten gibt. Mit zunehmender Distanz vom Samenbaum nimmt die Anzahl der
Keimlinge ab und dass dieser Effekt hängt mit den Eigenschaften der Samen zusammen. Das
Keimbeet der untersuchten Baumarten kann beschrieben werden, wobei nicht für jede Baumart ein spezifisches Keimbeet charakterisiert werden kann. Mit den GLMM lassen sich Vorhersagen zur Anzahl der Keimlinge bei gegebenen Samenbäumen und Mikrohabitat in weiteren
Beständen machen, welche als Hilfe bei der Waldbewirtschaftung gebraucht werden können.

description: Abstract

Seaweeds as a whole or parts are being used pharmacologically worldwide. In the present study, methanol extract of two marine algae, Ulva lactucaa (ULME) and Sargassum tenerrimum J.Agardh (1848) (STME) collected from, Mandapam Coastal region, Tamil Nadu had been tested for anti cancerous and toxic nature using cancer cell lines (MCF 7, MDA MB 232), Artemia sp. (BST), and Zebra fish embryos (Danio rerio, Hamilton, 1822). The anticancer activity was evaluated using MTT assay; Mortality was observed at 12h and 24h for BST assay. The developing zebra fish embryos (ZFE) were incubated with various concentrations of extracts from blastula to Hatching period (extended up to 144h). SWME showed relatively lower activity against those cell lines (54.57 44.54 against MCF 7 and MDA MB 231 cellsthan URME 35.76 and  33.64 µg/ ml respectively).  Brine shrimp nauplii were more sensitive to STME (LC50 144.5 and > 3000 µg/ ml) than ULME (165.9, 158.4 µg/ ml on 12h and 24h respectively). No mortality and deformities in the developing embryos were observed in both extracts.  But ULME affected hatching percentage at concentrations above 500 µg/ ml. Ten fold decrease was found on 1000 and 2000 µg/ ml than 0 – 500 µg/ ml up to 48h. Both extracts killed Artemia nauplii and cancer cells. But, ULME retarded the hatchability of ZFE without killing or teratogenicity. This study also confirms the need of further evaluation, about the identification of active biomolecule, and its selective toxicity on the mammalian cell lines in molecular level.

Udeina transvaalensis = Parachilota transvaalensis: NMSAD.
Type locality. NW, Potchefstroom (garden soil & potato-field).
Distribution. Known from two neighbouring sites in the North Western province, both from arable fields, Potchefstroom and Parys. Species findings in cultivated fields suggest transportation from other sites. Resampling of the known sites and in neighbouring areas is recommended.
Remarks. Holotype SMNH ‘type’-2658. Syntype NMSA/Olig.03875. After examination of the species description and syntype material it became clear that the acanthodriline characters (two pairs of prostates with their pores in 17 and 19, male pores in 18, and paired spermathecae in segment 8 and 9) indicate that this species belongs to the genus Parachilota. Reynolds & Cook (1976) indicate type material location at ZIPU (= NWUP). Syntype NMSA/Olig.03875, possibly from NWUP material.

Alyculus Kasantsev, 1999: 252.
Diagnosis. Body length 1–3 mm; antennae 11–segmented; mouthparts with reduced mandibles; pronotum strongly transverse and widest at posterior margin with laterally prominent hind angles; scutellum bifurcate at apex, each distal process curved laterad; elytra abbreviated; hind wings fully developed, exposed and only longitudinally folded; aedeagus with slender phallus, parameres widest in basal part and about as long as phallus.
Distribution. Southeast Asia: Sunda Shelf Islands (Borneo, Java, Sumatra) and the Malay Peninsula.
Remarks. Alyculus is the only net-winged beetle with abbreviated elytra occurring in the Oriental Region. Females are unknown despite quite a high number of specimens collected in recent years. Due to its morphological similarity to other lyropaeine beetles with unknown females (Antennolycus Bocáková & Bocák, 1999, Skrivania Bocáková & Bocák, 1999, Microlyropaeus Pic, 1929, etc.) and inferred relationships in molecular analyses (Bocakova et al. 2007; Bocak et al. 2008), we suggest that Alyculus females are also larviform when sexually mature.

Larval diagnosis. Larvae of N. penetrans can be distinguished from Isorhipis Boisduval and Lacordaire and Melasis Olivier larvae by the absence of annulets or pseudosegments between each abdominal segment. Presence of mesothoracic sclerome, along with microtrichial patches will further distinguish N. penetrans from larvae of Isorhipis and Melasis. The species can be distinguished from illustrated larvae of Hylochares nigricornis (Say) (Peterson 1951) by its prothoracic scleromes, that being T-shaped in N. penetrans and circular in H. nigricornis. Furthermore, N. penetrans can also be distinguished from Dirrhagofarsus ernae Otto, Muona and McClarin by its microtrichial patches on both mesothoracic and metathoracic segments, as well as the absence of microtrichial patch on the ninth abdominal terga. Presence of areole on both the dorsum and tergum of abdominal segment IX will also distinguish N. penetrans from D. ernae.
Specimens examined. Eight larvae and indeterminate number of triungulins collected at USA: Wisconsin: Oconto County, Rueckert’s private property, T29 N R17 E sec 16, 10 April 2007, 22 April 2007, 9 April 2009, Robert L.

description: We consider the problem of meeting deadline constraints in wireless communication networks. Fulfilling deadlines depends heavily on the routing algorithm used. We study this dependence generically for a broad class of routing algorithms. For analyzing the impact of routing decisions on deadline fulfillment, we adopt a stochastic model from operations research to capture the source-to-destination delay distribution and the corresponding probability of successfully delivering data before a given deadline. Based on this model, we propose a decentralized algorithm that operates locally at each node and exchanges information solely with direct neighbors in order to determine the probabilities of achieving deadlines. A modified version of the algorithm also improves routing tables iteratively to progressively increase the deadline achievement probabilities. This modified algorithm is shown to deliver routing tables that maximize the deadline achievement probabilities for all nodes in a given network. We tested the approach by simulation and compared it with routing strategies based on established metrics, specifically the average delay, minimum hop count, and expected transmission count. Our evaluations encompass different channel quality and small-scale fading conditions, as well as various traffic load scenarios. Notably, our solution consistently outperforms the other approaches in all tested scenarios.
