Soil fungi act like a support network for trees: study

U of A research is first to show that growth rate of adult trees is linked to fungal networks colonizing their roots

Soil fungi act like a support network for trees: studyBeing highly connected to a strong social network has its benefits. Now a new University of Alberta study is showing the same goes for trees, thanks to their underground neighbours. The study, published in the Journal of Ecology, is the first to show that the growth of adult trees is linked to their participation in fungal…

Shedding the destructive legacy of the baby boomers

Someone said, ‘Greed is good’ and we repeated it. But the only thing that matters when you die is your legacy

Shedding the destructive legacy of the baby boomersI have to apologize to the youth of the world for the state we find ourselves in. Yes, great things have happened in my lifetime. We watched the fall of the Berlin Wall and we have taken some steps in the progress of human rights. But the legacy of the baby boomer generation leaves little…

Wildfires, logging affect key fungi in pine forests: studies

Disturbances by humans or nature change the balance of fungi in soil, potentially making it harder for seedlings to regenerate

Wildfires, logging affect key fungi in pine forests: studiesDisturbances can hit Alberta’s lodgepole pine forests hard – including life under the soil, new University of Alberta research shows. Fungal communities that nourish pine tree roots are being altered by both human-made and natural disturbances, which can stress forests and make it tougher for pine seedlings to regenerate, said Jean Rodriguez Ramos, a PhD…

Butterflies ‘sentinels’ of climate change in mountain ecosystems

U of A scientists urge more monitoring of butterfly populations to help understand alpine environments predicted to change rapidly

Butterflies ‘sentinels’ of climate change in mountain ecosystemsMountains and butterflies are conceptualized as the ultimate juxtaposition – enduring and resolute versus fleeting and delicate – but the surprising robustness of alpine butterflies could help scientists better understand the impact climate change is having on mountains. In an essay written for the third annual State of the Mountains report by the Alpine Club of Canada, University…
