Evidence-based tool surpasses expert opinion in predicting probability of eradication of aquatic non-indigenous species
Download2015-01-01
Drolet, David, Locke, Andrea, Lewis, Mark A, Davidson, Jeff
The main objective of evidence-based management is to promote use of scientific data in the decision-making process of managers, with data either complementing or replacing expert knowledge. It is expected that this will increase the efficiency of environmental interventions. However, the...

Evolution of Conifer Diterpene Synthases: Diterpene Resin Acid Biosynthesis in Lodgepole Pine and Jack Pine Involves Monofunctional and Bifunctional Diterpene Synthases
Download2013-01-01
Jancsik, Sharon, Bohlmann, Jörg, Quesada, Alfonso L., Zerbe, Philipp, Yuen, Macaire, Hall, Dawn E., Dullat, Harpreet, Madilao, Lina L.
Diterpene resin acids (DRAs) are major components of pine (Pinus spp.) oleoresin. They play critical roles in conifer defense against insects and pathogens and as a renewable resource for industrial bioproducts. The core structures of DRAs are formed in secondary (i.e. specialized) metabolism via...

Background: Strigolactones (SLs) are a class of plant hormones that control many aspects of plant growth. The SL signalling mechanism is homologous to that of karrikins (KARs), smoke-derived compounds that stimulate seed germination. In angiosperms, the SL receptor is an α/β-hydrolase known as...

eeds are one of the most significant innovations in the land plant lineage, critical to the diversification and adaptation of plants to terrestrial environments. From perspective of seed evo-devo, the most crucial developmental stage in this innovation is seed maturation, which includes...

Evolutionary origins of sensation in metazoans: functional evidence for a new sensory organ in sponges
Download2014-02-11
Background One of the hallmarks of multicellular organisms is the ability of their cells to trigger responses to the environment in a coordinated manner. In recent years primary cilia have been shown to be present as ‘antennae’ on almost all animal cells, and are involved in cell-to-cell...

Experimental evidence for the rapid evolution of behavioral canalization in natural populations
Download2009
Lynch, B.R., Trussell, G.C., Palmer, A.R., Edgell, T.C.
Canalization—the evolutionary loss of the capacity of organisms to develop different phenotypes in different environments— is an evolutionary phenomenon suspected to occur widely, although examples in natural populations are elusive. Because behavior is typically a highly flexible component of an...

Tenniswood, M., Bennett, S., Wong, P., Morrissey, C., Nitsche, E., Guenette, R.S.
After hormonal ablation, 90% of the secretory epithelial cells of the prostate undergo apoptosis, and the remaining cells are reorganized as the tissue is remodeled. Using differential display RT-PCR of total RNA extracted from the rat ventral prostate before and 4 days after castration, we have...

Factors governing outbreak dynamics in a forest intensively managed for mountain pine beetle
Download2020-05-05
Mélodie Kunegel-Lion, MarkA. Lewis
Mountain pine beetle (MPB) outbreaks have caused major economic losses and ecological consequences in North American pine forests. Ecological and environmental factors impacting MPB life-history and stands susceptibility can help with the detection of MPB infested trees and thereby, improve...

Factors influencing flight capacity of the mountain pine beetle (Coleoptera: Curculionidae: Scolytinae)
Download2014-01-01
Evenden, Maya L., Whitehouse, C. M., Sykes, J.
The mountain pine beetle, Dendroctonus ponderosae Hopkins (Coleoptera: Curculionidae: Scolytinae) is the most damaging pest of mature pine (Pinaceae) in western North America. Although mountain pine beetles have an obligate dispersal phase during which adults must locate a new host for brood...
