Effects of habitat and acclimation temperature on cholesterol contents were examined in oceanic and inshore species of copepods. The cholesterol content of five species of thermally acclimated copepods was determined, and nine species (representing six families) were sampled to assess the role of habitat temperature. The species selected have maximum habitat temperatures (and temperature tolera...

Chromosome numbers of one species Eranthemum (E. macrophyllum Wall. ex Nees) and five Strobilanthes [S. affinis (Griff.) Terao J. R. I. Wood et Benett., S. biocullata Y. F. Deng & Wood, dimorphotricha Hance, heteroclita D. Fang H. Lo pseudocollina K. He Qin] in the family Acanthaceae from China have been reported for first time. The chromosome were determined as 2n=4x=44 E. macrophyllum, 2n=2x=...

A taxonomic study of the genus Furcilarnaca Gorochov, 2004 is presented. Four new species are described: F. affinis sp. nov., F. hirta sp. nov., F. fractiflexa sp. nov., F. brachyptera sp. nov.. Two new combinations F. fallax (Liu et al., 2010) comb. nov. and F. pulex (Karny, 1928) comb. nov. are given. A key to the species and the distributional data of Furcilarnaca are provided.

Eleven species of Mordellidae are newly recorded for New Brunswick, Canada. Six of these, Falsomordellistena discolor (Melsheimer), Falsomordellistena pubescens (Fabricius), Mordellistena ornata (Melsheimer), Mordellaria undulata (Melsheimer), Tomoxia inclusa LeConte, and Yakuhananomia bidentata (Say)are new for the Maritime provinces. Falsomordellistena pubescens is new to Canada. Pelecotoma f...

Five species previously usually treated as Dicranomyia (Dicranomyia) mitis (Meigen, 1830) are redescribed and named with already existing names, viz. D. (D.) mitis [s. str.], D. (D.) affinis (Schummel, 1829), D. (D.) quadra (Meigen, 1838), sp. restit., D. (D.) lutea (Meigen, 1804), and D. (D.) imbecilla Lackschewitz in Lackschewitz & Pagast, 1941, stat. n. All important characters of the wing, ...

The phytochemical study of flowering shoots of Caragana bungei Ledeb., Fabaceae, collected in Tuva Republic (Russian Federation) resulted in the isolation of sixteen compounds identified as β-sitosterol, β-sitosterol-3-Oglucoside, umbelliferone, kaempferol, quercetin, isorhamnetin-3-O-glucoside, isoquercitrin, rutin, narcissin, nicotiflorin, caffeic acid, 3-O-caffeoylquinic acid, 5-O-caffeoylqu...

Maintenance of genetic variation at loci under selection has profound implications for adaptation under environmental change. In temporally and spatially varying habitats, non-neutral polymorphism could be maintained by heterozygote advantage across environments (marginal overdominance), which could be greatly increased by beneficial reversal of dominance across conditions. We tested for revers...

A molecular tool, focused on the mitochondrial Control Region (CR), was developed to discriminate the two hawthorn-feeding psyllid species, Cacopsylla melanoneura (Förster) and C. affinis (Löw), and to estimate their frequencies in mixed populations. The test was carried out in paired and single-tube amplifications and validated analysing 52 male specimens previously determined by morphological...

17 Road verges have been proposed as refuges for vulnerable grassland species in the 18 modern, changing landscape, but little comparative knowledge exists on how 19 management regimes affect population dynamics of such species. We compared the 20 effects of various management regimes on population dynamics of Pimpinella saxifraga 21 in road verges and pastures, using elasticities and LTRE-anal...

Antibacterial activity of crude extracts of culinary spices like Aniseed (Pimpinella anisum), Star anise (Illicum verum Hook fruit) and Cinnamon (Cinnamomum zeylanicum) against some of the common fish bacterial pathogens like Aeromonas hydrophila, Aeromonas salmonicida and Edwardsiella tarda were explored by finding minimum inhibitory concentration (MIC). A twofold serial dilution of compounds ...
