Don't forget that this is considering a species distribution model (SDM) When using a multimodel approach, which includes both SDM and process-based models, iy appears that aspen might take advantage of increased climate-induced disturbances. Up to a certain point...

3/ 🌎 Most importantly, climate change is a bigger driver of SBW dynamics than landscape changes!
This means forest ecosystems are being reshaped faster than we expected, requiring adaptive management strategies.

2/ 📈 Key findings (1950–2022):
📍 +68 km northward shift of suitable climate conditions (up to 200 km in some areas!)
⏳ Earlier phenological events & higher reproduction rates in the north
❄️ Increased winter mortality in the south due to warmer temperatures

#ClimateChange is reshaping forest ecosystems, and the spruce budworm (Choristoneura fumiferana), a major boreal forest defoliator, is feeling the heat! 🔥
Our latest study in PLOS Climate reveals some striking trends. 🧵👇

5/ 🚫 What didn’t matter much?
Fire exclusion had minimal influence on vegetation composition, indicating that mesophication unfolds over longer timescales.
Modest climate change impacts (1830–2000) pale in comparison to timber harvesting, but future climate shifts could have stronger effects.

4/ 🔍 What did we find?
Timber harvesting had the most significant impact on forest dynamics:
🌳 Without harvesting, pre-settlement species composition & traits were largely maintained.
🔥 Fire shifts increased aspen, but their effects were secondary.
🌡️ Climate change had a minor role

3/ 🛠️ How did we study this?
We used the #LANDIS-II forest landscape model for retrospective analysis (1830–2000), integrating:
🔥 Historical #fire reconstructions
🌡️ #Climate reanalysis data
🌲 #Timber harvest records
Counterfactual scenarios helped isolate the impact of each factor.

2/ 🌳 What’s the study about?
#Forests in northeastern #NorthAmerica have undergone massive changes since pre-settlement times
🟩 Loss of conifers
🌲 Decline in taxonomic & functional diversity
We aimed to untangle the individual effects of timber harvesting, fire regimes, and climate on these shifts.

Simulated emissions from the 2023 wildfires were 8x their 1985–2022 average. Without action, the likelihood of extreme fire seasons—and their impacts on health, society, and ecosystems—will keep rising. 🌲🚨 (5/)

Using climate models, we show that human-driven climate change significantly increased the likelihood of such an extreme fire season across most of Canada. 🔥🌡️ In the east and southwest, the likelihood was more than doubled. (3/)

As mentioned by @meteomedia.bsky.social, several cities in #Quebec have recorded their warmest meteorological fall (SON) in 2024 since record began. A +3°C anomaly is quite something for a 3-month period.

9/ Conclusion: Even when the world is rapidly changing, focusing on #conserving a single species (like the #caribou) can have a ripple effect, benefiting a range of other species. It underscores the value of targeted #conservation efforts.
