two 60 day experiments on predation behavior of leeches were conducted concurrently. in the first, medicinal leeches, hirudo orientalis (utevsky and trontelj, 2005) were fed to satiation on bovine blood and subsequently transferred into two large opaque plastic containers of equal size but with differing temperatures, 6-7?c and 23-24?c, containing starved erpobdella octoculata (l.). at the high...

agronomic and physiological traits and protein expression were compared between non-bt glandless upland cotton variety-zhong5629 and its bt-transgenic near-isogenic lines differing in cryiac gene. results showed that the bt isogenic line had higher plant height and rate of effective bolls, more internal bolls but lower yield, than the non-bt line. the bt isogenic line had lower chlorophyll cont...

The introduction of a hydroxy group to the cholesterol skeleton introduces not only the possibility for positional isomers but also diastereoisomers, where two or more isomers have different configurations at one or more of the stereocentres but are not mirror images. The differentiation of diastereoisomers is important as differing isomers can have differing biochemical properties and are form...

This study is part of the Follow up Restoration Program of animal communities that colonize the Guadiamar River Basin. In 1998, the area was affected by a release of toxic sludge after the retention walls of the Aznalcóllar Mines (southern Iberian Peninsula) broke. The main objective of this study was to assess the current state of the population of Tenebrionidae, one of the most representative...
