The cuticular hydrocarbons of insects are species-specific and often function as semiochemicals. The activity of Tribolium brevicornis cuticular hydrocarbons as feeding deterrents that ostensibly function to prevent pupal cannibalism and predation was evaluated. The cuticular hydrocarbons of T. brevicornis pupae were characterized and flour disk bioassays conducted with individual and combined extract components incorporated into artificial diets on which Tribolium adults fed for six days. Feeding by T. brevicornis and T. castaneum on flour disks containing cuticular extracts of T. brevicornis pupae resulted in reduced consumption and weight loss relative to feeding on control flour disks. In both cases, feeding deterrence indices exceeded 80% suggesting that T. brevicornis cuticular hydrocarbons could function to deter cannibalism and predation of pupae by larvae and adult beetles. Sixteen different cuticular hydrocarbons were identified in T. brevicornis pupal extracts. Eight of the commercially available linear alkanes were tested individually in feeding trials with eight Tribolium species. One compound (C28) significantly reduced the amount of food consumed by three species compared to control disks, whereas the compounds C25, C26, and C27elicited increased feeding in some species. Four other compounds had no effect on consumption for any species. When four hydrocarbon mixtures were tested for synergistic deterrence on T. brevicornis and T. castaneum, none significantly influenced consumption. Our results indicate that the cuticular chemistry of T. brevicornis pupae could serve to deter predation by conspecific and congeneric beetles. [less ▲]

Habitat preferences of Atlantic salmon parr are commonly described using mean flow velocity, water depth, and substrate as habitat variables, and a variety of habitat models have been developed using these variables to predict habitat quality. However, Atlantic salmon parr live in highly turbulent streams and rivers, in which intense fluctuations of flow velocity occur. Habitat preferences that consider the high variability of flow velocity have not been studied, and this although it has been shown in laboratory experiments that turbulence may affect the behavior and energetics of fish. Consequently, we studied the use of turbulent flow by Atlantic salmon parr in Patapédia River, Québec, Canada using radio-telemetry. We analyzed summer habitat preferences of individual parr in relation to several dynamic hydraulic variables such as standard deviation of flow velocity, turbulent kinetic energy, Froude number, and shear stress, and compared them with the habitat availability within the river reach. Our results revealed that in a natural flow environment, parr display a high individual variability in habitat preferences in relation to flow turbulence. Such heterogeneous habitat preferences suggest that individuals are not constrained to single habitat types and exhibit flexible habitat use. Furthermore, no differences were observed in habitat preferences between the four daily periods (dawn, day, dusk, and night) within individual parr. [less ▲]

The BCG vaccine has demonstrated its efficacy to protect young children from severe extrapulmonary forms of tuberculosis. Nevertheless, the immunity induced by the vaccine disappears in adults and cannot be boosted by readministration of BCG. Adverse effects of BCG are rare, but potentially dangerous (i.e. disseminated vaccinal infections) and they justify the fact that BCG should not be administered anymore in Western European countries where the incidence of pediatric tuberculous meningitis is very low. The vaccine is still recommanded for children living in countries with high tuberculosis prevalence and for resident children leaving Belgium for these countries. [less ▲]

The study of biogeochemical processes in soil has long been restricted by the techniques available for investigating the micro-organisms concerned. In particular, isolated nitrifying bacteria are not active in culture media below pH 5.5-6.0, and it is not clear to what extent these strains, if at all, are active in the acid soils of temperate forests. Since DNA/RNA based microbiological techniques do not require isolation of bacterial strains, they provide a new, powerful approach to gain insight into the nitrification process. We therefore combined the use of a large scale field experiment and laboratory soil incubations with molecular analysis of the nitrifying bacterial community to investigate the effect of dolomite lime on the nitrification process in the soil of the Belgian Ardenne. In this area, soils are naturally poor in magnesium and liming at moderate doses has been suggested to alleviate soil acidification and nutritional deficiencies. However, possible side effects needed to be evaluated, in particular on the nitrification process. As nitrification may be linked to soil acidification, cation leaching, aluminium mobilisation and N2O emission, increased knowledge is essential when evaluating effects of global environmental change and management strategies on forest ecosystems. The effects of dolomite lime (3-5 T/ha) were investigated at the watershed (80 ha, mainly Picea abies), plot (Quercus petraea and Picea abies stands) and laboratory level. Runoff chemistry, soil solution, net nitrate production in the laboratory and the community structure of ammonium oxidising bacteria (by PCR amplification of 16S-RNA genes, Denaturing Gradient Gel Electrophoresis - DGGE, sequence analysis and hybridisation) were analysed. In the watersheds, consequences on runoff water chemistry were minor. However, in the plot study, soil solution nitrate concentrations were significantly increased through liming in the Quercus plots. Increased net nitrification in the Quercus stand was confirmed by potential net nitrification measurements in the laboratory, whereas soil pH rose in both stands. The impact of liming on potential net nitrification was not related to a shift in the 16S rDNA DGGE community profile of ammonia-oxidising bacteria. The DDGE profile, combined with hybridisation and sequencing of cut out bands revealed a dominance of Nitrosomonas europea-like sequences and a minor presence of Nitrosospira cluster 2-like sequences. These results contrast with several reports suggesting a dominance of Nitrosospira-like organisms among ammonia oxidiser communities in acid soils. Our study reflects the great potential of combining new molecular techniques with conventional methods for improving our knowledge on the ecology of biogeochemical processes. [less ▲]
