Haemoproteus cyanomitrae sp. nov. (Haemosporida: Haemoproteidae) from a widespread African songbird, the olive sunbird, Cyanomitra olivacea.
Haemoproteus ( Parahaemoproteus ) cyanomitrae n. sp. (Haemosporida: Haemoproteidae) was found in the olive sunbird, Cyanomitra olivacea (Nectariniidae), in rain forests of tropical Africa. It is described based on the morphology of its blood stages and a segment of the mitochondrial cytochrome b gene (GenBank accession FJ404696), which can be used for molecular identification and diagnosis of t...

متن کاملAllometry of kinematics and energetics in carpenter bees (Xylocopa varipuncta) hovering in variable-density gases.
We assessed the energetic and aerodynamic limits of hovering flight in the carpenter bee Xylocopa varipuncta. Using normoxic, variable-density mixtures of O(2), N(2) and He, we were able to elicit maximal hovering performance and aerodynamic failure in the majority of bees sampled. Bees were not isometric regarding thorax mass and wing area, both of which were disproportionately lower in heavie...
متن کاملPollination of Blueberry (vaccinium Ashei) by Honey Bees (apis Mellifera) and Nectar-thieving Carpenter Bees (xylocopa Virginica)
In a 2000 field study in which mature plants, potted pollenizers, and 0-12800 honey bees were tented together, honey bees were shown to effectively pollinate rabbiteye blueberry, variety “Climax.” There was a consistent and significant increase in fruit-set and number of seeds as bee numbers increased within the range of 0-6400 bees. In conference, the authors will present results of a 2001 fie...
