Predicting Dendroctonus pseudotsugae (Coleoptera: Curculionidae) Antiaggregation Pheromone Concentrations using an Instantaneous Puff Dispersion Model

Creator:: Strand, Tara M., Ross, Darrell W., Thistle, Harold W., Ragenovich, Iral R., Guerra, Ivonne Matos, and Lamb, Brian K.
Abstract:: An instantaneous puff dispersion model was used to assess concentration fields of the Douglas-fir beetle, Dendroctonus pseudotsugae Hopkins, antiaggregation pheromone, 3-methylcyclohex-2-en-1-one (MCH), within a 1-ha circular plot. Several combinations of MCH release rate and releaser spacing were modeled to theoretically analyze optimal deployment strategies. The combinations of MCH release rate...

Creator:: Shelton, Glenn W. K., Stockey, Ruth A., Rothwell, Gar W., and Tomescu, Alexandru M. F.
Abstract:: PREMISE OF THE STUDY: Mosses, very diverse in modern ecosystems, are currently underrepresented in the fossil record. For the pre-Cenozoic, fossil mosses are known almost exclusively from compression fossils, while anatomical preservation, which is much more taxonomically informative, is rare. The Lower Cretaceous of Vancouver Island (British Columbia, Canada) hosts...

A Lower Cretaceous (Valanginian) seed cone provides the earliest fossil record for Picea (Pinaceae)

Creator:: Klymiuk, Ashley A. and Stockey, Ruth A.
Abstract:: Premise of study: Sequence analyses for Pinaceae have suggested that extant genera diverged in the late Mesozoic. While the fossil record indicates that Pinaceae was highly diverse during the Cretaceous, there are few records of living genera. This description of an anatomically preserved seed cone extends the fossil record for...

Abstract:: Premise of the study: Pinaceae and nonpinoid species are sister groups within the conifer clade as inferred from molecular systematic comparisons of living species and therefore should have comparable geological ages. However, the fossil record for the nonpinoid lineage of extant conifer families is Triassic, nearly 100 million years older...
