Open AccessImpact of nutritional stress on the honeybee colony health
Honeybees Apis mellifera are important pollinators of wild plants and commercial crops. For more than a decade, high percentages of honeybee colony losses have been reported worldwide. Nutritional stress due to h...

Characterization of Nosema ceranae Genetic Variants from Different Geographic Origins
In recent years, large-scale colony losses of honey bees (Apis mellifera) have been reported and the infection with the microsporidia Nosema ceranae has been involved. However, the effect of N. ceranae at the col...

Multidisciplinary approach to constrain kinematics of fault zones at shallow depths: a case study from the Cameros–Demanda thrust (North Spain)
Thrusting at shallow depths often precludes analysis by means of structural indicators effective in other geological contexts (e.g., mylonites, sheath folds, shear bands). In this paper, a combination of techn...

Determination of Flower Constancy in Bombus atratus Franklin and Bombus bellicosus Smith (Hymenoptera: Apidae) through Palynological Analysis of Nectar and Corbicular Pollen Loads
The flower constancy (the visit to a single plant species during a foraging trip) in pollinator insects is a theme widely discussed in behavioral ecology and has an important implication in the evolution of an...

Optimal quantum estimation of the coupling constant of Jaynes-Cummings interaction
We address the estimation of the coupling constant of the Jaynes-Cummings Hamiltonian for a coupled qubit-oscillator system. We evaluate the quantum Fisher Information (QFI) for the system undergone the Jaynes...

Intracolonial genetic variability in honeybee larval resistance to the chalkbrood and American foulbrood parasites
The origin of multiple mating of queens in social Hymenoptera is a widely debated topic in evolutionary biology. One of the hypotheses is that genetic variability would benefit the colony by increasing its res...

Organic Working Fluid Optimization for Space Power Cycles
The merits of organic fluid space power cycles are surveyed and compared with those of alternate options. Selection of an optimum working fluid is recognized as an important tool to improve system performance....
