The effect of food supplementation on reproductive success in bumblebee field colonies

Article Abstract:

The effects of richer long-term food availability on the development and reproductive success of bumblebee field colonies are investigated. The possibility of reduction in the incidence and severity of nest parasitism by colonies with increased resources is examined.

Edge-mediated effects on stand dynamic processes in forest interiors: a coupled field and simulation approach

Article Abstract:

The dynamic influences that edges may have on processes in adjacent areas are examined. The woody species composition in gaps and non-gap areas with the interior of an Ohio hardwood forest with a simple cellular automata model of forest dynamics is analyzed.

Are wing size, wing shape and asymmetry related to field fitness of Trichogramma egg parasitoids?

Article Abstract:

The effects of wing shape, wing size and fluctuating asymmetry on the field fitness of Trichogramma near brassicae and Trichogramma pretiosum are examined. The shape and size dimensions are linearly associated with fitness.
