AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
The genus Eudicella White comprises horned cetoniines widespread in the sub-Saharan Africa. Two subgenera, Eudicella (Eudicella) White and Eudicella (Cyprolais) Thomson, compose the genus. Here, the remarkably uniform subgenus Eudicella (Eudicella) is revi ...
The complex of Dicronorhina Hope taxa without cretaceous marks on head and body (“micans group”) is here diagnosed, discussed and revised. The type species of the genus, Scarabaeus micans Drury, 1773, is identified and re-described. D. johnstoni Waterhouse ...
Invasive species are nowadays considered as one of the most important threat to biodiversity. By displacing native species, modifying ecosystem functioning and causing substantial losses to agricultural production, they represent a menace to natural and ma ...
Good taxonomy is essential for ecological, biogeographical, and evolutionary studies of any group of organisms. Therefore, we performed detailed light- and scanning electron microscopy (SEM) investigations on the shell ultrastructure and biometric analyses ...
A cell-grid method was used to survey seasonal changes in four herbaceous communities of a wooded pasture. Permanent plots consisted in 1-m3 grids subdivided into 100 cells of 1 dm2. In each cell of each plot and every month from May to September, we estim ...
Interpreting the functional diversity of vegetation is important in unravelling the relationship between environmental change, community composition and ecosystem processes. Functional diversity is the range and distribution of functional trait values i ...
A multi-gas photoacoustic sensor is reported. Simultaneous measurement of ammonia, carbon dioxide and water vapor is demonstrated at ppm level using semiconductor lasers. In-situ measurements to control the housing conditions of laboratory animals are pres ...
Megalorhina Westwood (type species: Ceratorhina (Megalorhina) harrisii Westwood, 1847) was synonymysed previously with Amaurodes Westwood (type species: Ceratorhina (Amaurodes) passerinii Westwood, 1844), and Amaurodes ranked as a subgenus of Mecynorhina H ...
We report on the experimental achievement of narrow ultraviolet excitonic and biexcitonic emission from GaN/AlGaN quantum wells. The very large biexciton binding energy (up to 12 meV) inhibits thermalization between the two species allowing to study the re ...
Toluene interaction with the catalysts consisting of 0.35, 0.62, 0.75 and 3.7 monolayers (ML) of VOx supported on anatase–titania, containing potassium, was studied by transient response techniques at 523–673 K. FT-Raman spectroscopy under dehydrated condi ...
