Disturbance interactions have profound consequences for forest health, yet remain poorly understood.

Here we use DAGs to differentiate #Synergisms, #CompoundDisturbances & #NetworkEffects and review the impacts of climate change.

Forest structural and functional diversity can attenuate forest productivity losses after harvesting and fires. In undisturbed forests, dominance boosts productivity via selection effects, but not after harvesting🌳🌲🌍

Old-growth forests 🌲store lots of carbon and support biodiversity. Recent study of 3,503 tree rings across Europe shows that older forests, especially those with large trees, are crucial for long-term carbon storage, highlighting the need to protect them.👍

Headline: Ticks are thriving in Southwest Virginia. Here's What That Means for Your Health. By Katie Burke Intro paragraph: Southwest Virginia is a hotspot for tick-borne disease--with some of the highest per-person rates of Lyme disease in the state. That rise has happened over the past 20 years. Jenny Hall, public health expert at Radford University and founder of the website Ticks in Virginia, stands in front of her table at a public health fair put on by Blue Ridge Literacy. Hall is a white woman with blond hair and blue eyes. She's wearing a black fleece jacket and khaki pants.

Hi people. Today in "one day, one paper", thermal tolerance breadth in plants exceeds local climate ranges, shaped mainly by heat, cold, and aridity. Desert species show extreme resilience, revealing partial support for climate variability hypothesis and highlighting microclimate-driven plasticity🌎🍁
