Architecture of the wood-wide web: Rhizopogon spp. genets link multiple Douglas-fir cohorts.

*The role of mycorrhizal networks in forest dynamics is poorly understood because of the elusiveness of their spatial structure. We mapped the belowground distribution of the fungi Rhizopogon vesiculosus and Rhizopogon vinicolor and interior Douglas-fir trees (Pseudotsuga menziesii var. glauca) to determine the architecture of a mycorrhizal network in a multi-aged old-growth forest.

Characterization of microsatellite loci for the pitcher plant midge, Metriocnemus knabi Coq. (Diptera: Chironomidae).

As a component of the inquiline community of the purple pitcher plant (Sarracenia purpurea), the pitcher plant midge Metriocneus knabi has been the subject of various ecological studies. However, very little is known about its characteristics beyond the larval stage, in particular the dispersal ability of adults. This study presents new molecular tools developed for testing of evolutionary and ecological questions in natural populations of this species.

Characterization of microsatellite loci for the western cherry fruit fly, Rhagoletis indifferens (Diptera: Tephritidae).

The western cherry fruit fly (Rhagoletis indifferens) is a major pest of cherry crops in western North America, yet relatively little is known about its population structure or movement patterns due to the difficulty of studying these parameters directly in the field. We isolated and characterized a set of 16 polymorphic microsatellite loci specific to R. indifferens that display sufficient polymorphism to assess genetic structure and movement patterns.
