Mature larvae and pupae of Lixus (Eulixus) canescens Steven, 1829 (Curculionidae: Lixinae: Lixini) are described and compared with known larvae and pupae of other Lixus species. The biology of the species was studied in Ukraine. A species of Crambe (Brassicaceae) was identified as host plant of both larvae and adults of this weevil. The weevil is very likely oligophagous. Lixus canescens prefer...

Abstract Understanding how the salt marsh vegetation will evolve under future climate conditions is essential for predicting role of ecosystem services in a warmer with higher CO 2 -concentrations. In mesocosm experiment northern Wadden Sea, impact increased temperature (+ 3 °C) and (800 ppm) on was investigated, assessing biomass production pioneer zone low marsh. The zone, which dominated by ...

Abstract Scopoletin is a phytochemical of coumarins distributed in some plants. The aim this study was the evaluation scopoletin content and antioxidant activity nettle, mallow, purslane, knot-grass, dill coriander encountered Black Sea regions. Analyses were conducted on leaves stems these plants, except knot-grass. lowest found nettle (11.48 mg/kg) highest amount knot-grass (6708.37 mg/kg). n...

Chlorophyll-containing cells of algae, photosynthetic bacteria, and plants often exhibit strong red luminescence when heated to temperatures above 70 °C. This high-temperature thermoluminescence (HTL) originates mostly from thermally induced degradation of lipid cycloperoxides present in thylakoid membranes. The degrading cycloperoxides can transiently form carbonyl species in excited triplet s...

Geological evolution of the Indian and Pacific Ocean basins, including the Tethys Sea, is relevant to the evolution and distribution of Indo-Pacific freshwater fishes. Area cladograms derived from phylogenetic analyses of atherinomorph fishes are compared, in part, with those for plant bugs, cicadas and bats. Geologically and biologically composite islands in the Indo-Australian archipelago suc...

An investigation of atmospheric mercury was conducted in the urban coastal zone of the Gulf of Gdansk (Baltic Sea, Poland) in 2008. Rainwater samples were collected in bulk samplers and Hg concentration was determined using AAS method. Total mercury concentration ranged from 1.9 to 14.8 ng l(-1) (the mean was 8.3 ng l(-1) with standard deviation ±3.7), out of which about 34 % were water-soluble...

and its tourist industry, a new report, commissioned by the UN Development Programme, with British and Caribbean partners, highlights the threat to other tropical islands. Released at the Cancún meeting, it estimates in detail the impacts of rising sea level on the 15 member Caribbean states of the Caricom regional community. While many of the islands are mountainous, the report highlights that...

Deep-Sea in-situ radioactivity measurements were initiated in 1964 for investigation of sunken USN atomic power submarine Thresher by using Geiger counters (Wakelin, 1964). Since then, in-situ radioactivity monitoring utilizing a towed-fish and/or remote sea bottom stations has been carried out in various countries. But they are mainly used for surveys of artificial radio activities to evaluate...
