Effects of recent wildfires on giant sequoia groves were anomalous at millennial timescales: a response to Hanson et al. Open
Background The giant sequoia ( Sequoiadendron giganteum [Lindley] Buchholz) of California’s Sierra Nevada recently suffered historically unprecedented wildfires that killed an estimated 13–19% of seed-bearing sequoias across their native r…
Assessing giant sequoia mortality and regeneration following high‐severity wildfire Open
Fire is a critical driver of giant sequoia ( Sequoiadendron giganteum [Lindl.] Buchholz) regeneration. However, fire suppression combined with the effects of increased temperature and severe drought has resulted in fires of an intensity an…
Post-fire reference densities for giant sequoia seedlings Open
In some areas burned by recent wildfires, most or all giant sequoias were killed. Sequoia managers wish to know whether post-fire seedling establishment in those areas has been adequate to regenerate the locally extirpated sequoias. To pro…

Chemical defense strategies, induction timing, growth, and trade‐offs in<i>Pinus aristata</i>and<i>Pinus flexilis</i> Open
Trade‐offs between plant defense investment and fitness traits, including growth, are often invoked to explain evolutionary strategies targeted at resisting herbivores. Many Pinus species have specialized herbivores, including the mountain…
Lignin concentrations in phloem and outer bark are not associated with resistance to mountain pine beetle among high elevation pines Open
A key component in understanding plant-insect interactions is the nature of host defenses. Research on defense traits among Pinus species has focused on specialized metabolites and axial resin ducts, but the role of lignin in defense withi…
Susceptibility of High-Elevation Forests to Mountain Pine Beetle (Dendroctonus ponderosae Hopkins) Under Climate Change Open
Across western North America, pine forests are important for timber, wildlife habitat, and at high elevations are important for water retention and yield from rain and snowmelt. The mountain pine beetle (MPB) is one of the most significant…
Lignin accumulation in phloem and outer bark is not associated with resistance to mountain pine beetle in high elevation pines Open
A key component in understanding plant-insect interactions is the nature of host defenses. Research on defense traits among Pinus species has focused on specialized metabolites and axial resin ducts, but the role of lignin in defense withi…
Field Translocation of Mountain Pine Beetles Suggests Phoretic Mite Communities Are Locally Adapted, and Mite Populations Respond Variably to Climate Warming Open
Temperature is a key determining factor in the population dynamics of forest insects and their associated biota. Bark beetles, often considered key agents of change in forest ecosystems, are particularly affected by warming in their enviro…
