Plant Species Biology   29 212-215   Jan 2014
To observe temporal changes in the nectar volume of Impatiens flowers, we modified and used an interval-shooting camera with a special flash system. Former methods of measuring nectar volume inevitably necessitated destruction or damage of the flo...

To clarify if bumblebees can recognize nectar through its scent in Impatiens textori flowers, we examined the behavior of Bombus diversus on nectarless flowers in which the spurs had been artificially removed. Bumblebee visits to both natural flow...

Most estimations of the pollination efficiency of insects have been based on observation by the naked human eye. However, insect behaviors are often too rapid to analyze sufficiently this way. Here we demonstrate the use of high-speed cameras to a...
