A mathematical model to capture complex microstructure orientation on insect wings.
Microstructures on insect wings can promote directional drop shedding, and the local orientation of these structures is expected to facilitate drop removal. However, microstructures may exhibit very different orientations at different locations on the wing. Using the march fly Penthetria...
We used mark-recapture methods to estimate the number of Parnssius smintheus (Papilionidae) butterflies moving among 20 alpine meadows separated by varying amounts of forest along the east slope of the Rocky Mountains in Alberta, Canada. We combined generalized additive models and generalized...
With up to 20,000 species of insects throughout Alberta the opportunities for entomological study are immense. An entomological reconnaissance study of the Syncrude Lease #17 area was required to gain preliminary data and to examine the potential of insects as biological monitors of...
Background The mountain pine beetle (Dendroctonus ponderosae) is a significant coniferous forest pest in western North America. It relies on aggregation pheromones to colonize hosts. Its three major pheromone components, trans-verbenol, exo-brevicomin, and frontalin, are thought to arise via...
Implementation of a marauding insect module (MIM, version 10) in the integrated bIosphere simulator (IBIS, version 26b4) dynamic vegetation–land surface modelDownload
Insects defoliate and kill plants in many ecosystems worldwide. The consequences of these natural processes on terrestrial ecology and nutrient cycling are well established, and their potential climatic effects resulting from modified land–atmosphere exchanges of carbon, energy, and water are...
Insects on the Suncor dike, a survey of the types present and an evaluation of their effects on dike vegetationDownload
An insect survey of the Suncor dike showed that these animals were abundant. Representatives of 50 insect families were collected in sweep net samples, and additional families were observed to be present. Grasshoppers belonging to at least five different species were collected, as were...
Between August 18 and September 30,1978, insect communities of 12 homogeneous habitats, chosen as representative of the major vegetation types, were sampled in the Alberta Oil Sands Environmental Research Program (AOSERP) study area (56°21' to 58°00' N and 110°50' to 112°00' W). Soil and...
