Molecular and microscopic analysis of the gut contents of abundant rove beetle species (Coleoptera, Staphylinidae) in the boreal balsam fir forest of Quebec, copyright
Experimental research on beetle responses to removal of logging residues following clearcut harvesting in the boreal balsam fir forest of Quebec revealed several abundant rove beetle (Staphylinidae) species potentially important for long-term monitoring.To understand the trophic affiliations of these species in forest ecosystems, it was necessary t
The golden mimicry complex uses a wide spectrum of defence to deter a community of predators
Mimicry complexes typically consist of multiple species that deter predators using similar anti-predatory signals.Mimics in these complexes are assumed to vary in their level of defence from highly defended through to moderately defended, or not defended at all.Here, we report a new multi-order mimicry complex aptamil allerpro that includes at leas
Design and manufacturing of the antenna motion mechanisms of a communication satellite
In this paper, design and simulation of a deployment and chainsaw file release mechanism of a communication satellite antenna are described.Because of the simplicity and reliability of the system, a torsion spring is used to excite the antenna.Dynamic simulation is performed by Adams Software and the appropriate spring and damper are selected for t
