Effects of flower patch additions and urbanisation on cavity‐nesting bees and wasps Urbanisation can negatively affect cavity-nesting bees and wasps, yet common conservation interventions such as flower patches and artificial nests lack strong empirical support. In a 2-year experime...

New paper out today (my final PhD chapter)! Increasing impervious surfaces strongly reduces cavity-nesting bee and wasp communities, and flower patches alone showed no detectable impact. @aer-ese-bes.bsky.social #openaccess

Global Trends in Drought Impacts on Wildlife—A Review We reviewed peer reviewed literature pertaining to instances of anomalous drought (any drought event that deviates from standard conditions (e.g., dry season) when compared to a long term average) an...

New paper from our lab, led by Leah McTigue
We reviewed 40+ years of research on drought affects on wildlife: 66% of single-species responses were negative, only 2% positive.
As droughts intensify under climate change, wildlife are in trouble. 🌍🌐🧪

I have a story out in @columbiainsight.bsky.social with numbers (lots of numbers) showing how two recently delisted PNW plant species have seen steep population declines since their federal protections were removed. Both plants were delisted because the USFWS argued they had fully recovered.

Diverse historical fire disturbance and successional dynamics in Douglas‐fir forests of the western Oregon Cascades, USA We created the first annually resolved records of historical fire occurrence coupled with precise estimates of tree establishment for the northern half of the west slope of the Oregon Cascades, a reg...

My colleagues Calvin Farris (NPS) and Ellis Margolis (USGS) led a landmark study in paleofire reconstruction. In addition to showing that fire management can restore past fire regimes, the demonstrated methods are a first in dendrochronology. 1/6 esajournals.onlinelibrary.wiley.com/doi/10.1002/...

Species shift their ranges in response to climate change, but many can't keep up. The resulting "community-climate disequilibrium" can impair ecosystem function and cause counterintuitive dynamics, like short-term gain but long-term loss onlinelibrary.wiley.com/doi/10.1111/...

2025 was the third-hottest year in Oregon in records that date back to 1895.
This year’s heat wasn’t as obvious — coming at night and in spring, late fall and early winter (hence the crap snowpack). It was also dry, but not that wildfire-y. Full story: tinyurl.com/dauh9e64
