Long‐Term Temporal Divergence in Post‐Drought Resilience Decline Between Deciduous and Evergreen Tree Species Severe drought increasingly threatens the resilience of forest biomes worldwide. Using a tree-ring database from Canadian forests, encompassing 40,147 trees across 4558 plots and 23 species, we analy...

Canada’s forests are losing their ability to bounce back from drought—and we now have the data to show it - Using tree-ring data from 40,000+ trees across 4558 plots and 23 species, we explored how trees responded to drought over the past century In GCB onlinelibrary.wiley.com/doi/10.1111/...

One year in: reflections from the IJWF Co-Editor-in-Chief

It has now been a year since I stepped into the role of co-Editor-in-Chief of the International Journal of Wildland Fire (IJWF). I find myself with a moment to reflect on this transformative experience. www.publish.csiro.au/wf/Fulltext/...

Drying Spring Accelerates Transitions Toward Pyrogenic Vegetation in Eastern Boreal North America Over the past 8000 years, spring climatic conditions, particularly drought, have been the primary driver of wildfire dynamics in eastern boreal North America. Increasing spring dryness over the last ....

New paleofire study! Spring droughts have intensified over the past 250 years, reshaping fire seasonality in eastern Canada. Spring is now nearly as flammable as summer, driving infrequent but large and severe fires 🌲🔥 onlinelibrary.wiley.com/doi/10.1111/...

Drivers and Impacts of the Record-Breaking 2023 Wildfire Season in Canada - Nature Communications The record-breaking 2023 wildfire season in Canada ( ~ 15 Mha burned) was enabled by early snowmelt, drought, and extreme weather. It had profound impacts that included evacuation of >200 communiti...

New paper published in @NatureComms The 2023 fire season in Canada is a wake-up call: severe climate impacts on fire activity are arriving decades earlier than predicted. Building fire-resilient environments is now more critical than ever! www.nature.com/articles/s41...

Excited to announce that I’ve been appointed co-Editor-in-Chief of the International Journal of Wildland Fire. It's an incredible opportunity to lead and support groundbreaking research in fire science! publish.csiro.au/wf

Future carbon sequestration potential in a widespread transcontinental boreal tree species: Standing genetic variation matters! Global Change Biology is an environmental change journal tackling issues such as sustainability, climate change and environmental protection.

Congrats to Etienne Robert for this paper in GCB fusing tree rings & genomics in ecological forecasting: genetically differentiated boreal black spruce populations harbor variation that could play a crucial role in productivity and growth under climate change onlinelibrary.wiley.com/doi/10.1111/...

Boreal forest cover was reduced in the mid-Holocene with warming and recurring wildfires - Communications Earth & Environment The boreal forest transformed into a dry oak-pine ecosystem in the hemiboreal zone of North America 7000 years ago, probably as a result of rising temperatures and increased fire activity, according t...

New study: The anticipated increase in Canadian #wildfire disturbances due to anthropogenic #ClimateChange will reduce the extent of the southern #boreal forest and hamper land use, mirroring transformations observed around 7,000 years ago www.nature.com/articles/s43...

Our new study examines how trees adjust drought and frost responses to local climates across Canada's vast forests. Some species adapt, others don't. More data needed to predict future impacts of climate change besjournals.onlinelibrary.wiley.com/doi/10.1111/...

Thanks Ben! But what do you mean about the species' proportions time plot being terrifying?

Our groundbreaking tree-ring study, just published in @NatureComms, uncovers compelling evidence of decreasing tree growth rates across Canadian forests from 1951-2018, linked to rising summer temperatures #Drought #TreeRing www.nature.com/articles/s41...
