Plants were subjected to 0.2%, 10%, 20%, 40%, 60% and 80% sea water dilutions (or 0.076, 3.8, 7.6, 15.2, 22.8, and 30.4 parts per thousand) for 11 weeks. Increase in salinity from 0.2% to 20% sea water had no effect on total dry biomass accumulation, while further increase in salinity to 80% sea water significantly decreased biomass by over 50%.

Key words: Larval morphology, Neuropterida, Myrmecaelurini, Gepini, antlion, Western Palaearctic Introduction Gepus Navás, 1912 and Solter Navás, 1912 are two closely related genera of Myrmeleontidae, representing a characteristic element of the antlion fauna of the arid and desert environments of the south-western Palaearctic region. Gepus is a small genus, comprising 6 valid species (Hölzel 1983) distributed in the Sahara desert and Middle East.

This addition increases the number of British species of the order Zygentoma from two to three, all in the family Lepismatidae. INTRODUCTION Silverfish, firebrats and bristletails were formerly grouped in a single order, the Thysanura (Delany, 1954), but silverfish and firebrats are now recognized as belonging to a separate order, the Zygentoma (Barnard, 2011).

This study is aimed at evaluating the chemical properties and ethnomedicinal uses of A. horridus. Results of the current study are based on data derived from several online databases such as Scopus, Google Scholar, PubMed and Science Direct, and pre-electronic sources such as scientific publications, books, dissertations, book chapters and journal articles. This study revealed that the fruit and root infusions and/or decoctions of A. horridus are used as traditional medicine for arteriosclerosis, chest pains, gastro-intestinal disorders, kidney problems, nausea and sexually transmitted infections. Phytochemical compounds identified from the species include cucurbitacins, fatty acids and sterols. Some of the compounds identified from the species have applications in food industry and health promoting products. Keywords: Acanthosicyos horridus, Cucurbitaceae, indigenous pharmacopeia, traditional medicine. INTRODUCTION “thorn” and a Latin term “sicyoideus” meaning “gourd- shaped”, that is, swollen below with narrow neck Acanthosicyos horridus Welw. ex Hook. f. is a above, in reference to the spines on the fruit [18]. The perennial shrub belonging to the Cucurbitaceae family, specific name “horridus” is from a Latin verb “horrere” often called cucurbits or the gourd family.

Bach de Roca Molero–Baltanás, R., Gaju–Ricart, M. & Bach de Roca, C., 2005. Ctenolepisma almeriensis n. sp. of Lepismatidae (Insecta, Zygentoma) from south–eastern Spain. Animal Biodiversity and Conservation, 28.1: 91–99. Abstract Ctenolepisma almeriensis n. sp. of Lepismatidae (Insecta, Zygentoma) from south–eastern Spain.— Ctenolepisma almeriensis n. sp., from the south–eastern part of the Iberian Peninsula is described. This species was determined previously as Ctenolepisma lineata (Fabricius, 1775), which is widespread over the south–western Palaeartic region. The main difference between the two species is the setation of thoracic sternites. In each bristle–comb of the mesosternum and the metasternum, macrosetae are arranged in a single row in C. lineata and in two parallel rows in C. almeriensis n. sp. In the prosternum, the first species shows 1–2 irregular lines of macrosetae per comb, and the new species shows 2–3 lines. Based on other parameters of setation, a discriminant analysis was carried out to separate a group of Spanish specimens of C. lineata from another group of specimens of the new species. This analysis demonstrated the validity of the occurrence of double or single lines of macrosetae in thoracic sternites to distinguish between the two species. Key words: Ctenolepisma almeriensis n. sp., Ctenolepisma lineata, Spain, Thysanura, New species, Arid regions fauna Resumen Ctenolepisma almeriensis sp. n. de Lepismatidae (Insecta, Zygentoma) de España suroriental.— Se describe Ctenolepisma almeriensis sp.

  • Trifurcatia Flabellata N. Gen. N. Sp., a Putative Monocotyledon Angiosperm from the Lower Cretaceous Crato Formation (Brazil)
    Mitt. Mus. Nat.kd. Berl., Geowiss. Reihe 5 (2002) 335-344 10.11.2002 Trifurcatia flabellata n. gen. n. sp., a putative monocotyledon angiosperm from the Lower Cretaceous Crato Formation (Brazil) Barbara Mohrl & Catarina Rydin2 With 4 figures Abstract The Lower Cretaceous Crato Formation (northeast Brazil) contains plant remains, here described as Trifurcatia flabellata n. gen. and n. sp., consisting of shoot fragments with jointed trifurcate axes, each axis bearing a single amplexicaul serrate leaf at the apex. The leaves show a flabellate acrodromous to parallelodromous venation pattern, with several primary, secondary and higher order cross-veins. This very unique fossil taxon shares many characters with monocots. However, this fossil taxon exhibits additional features which point to a partly reduced, and specialized plant, which probably enabled this plant to grow in (seasonally) dry, even salty environments. Key words: Plant fossils, Early Cretaceous, jointed axes, amplexicaul serrate leaves, Brazil. Zusammenfassung In der unterkretazischen Cratoformation (Nordostbrasilien) sind Pflanzenfossilien erhalten, die hier als Trifurcatia flabellata n. gen. n. sp. beschrieben werden. Sie bestehen aus trifurcaten Achsen, mit einem apikalen amplexicaulen facherfonnigen serra- ten Blatt. Diese Blatter zeigen eine flabellate bis acrodrorne-paralellodromeAderung mit Haupt- und Nebenadern und trans- versale Adern 3. Ordnung. Diese Merkmale sind typisch fiir Monocotyledone. Allerdings weist dieses Taxon einige Merkmale auf, die weder bei rezenten noch fossilen Monocotyledonen beobachtet werden. Sie miissen als besondere Anpassungen an einen (saisonal) trockenen und vielleicht iibersalzenen Lebensraum dieser Pflanze interpretiert werden.
