How rising temperatures could lead to population crashes

How rising temperatures could lead to population crashes

Researchers at Rice University have uncovered a critical link between rising temperatures and declines in a species’ population, shedding new light on how global warming threatens natural ecosystems. The study, published in Ecology and led by Volker Rudolf, revealed that rising temperatures exacerbate competition within populations, ultimately leading to population crashes at higher temperatures. It…

Why ‘leaky’ plants could accelerate climate change

Why ‘leaky’ plants could accelerate climate change

Plants play a key role in regulating Earth’s climate, but recent research suggests that rising temperatures could disrupt this balance, because plants are leaking more water than previously thought. UBC assistant professor Dr. Sean Michaletz, a newly minted Sloan Research Fellow in the department of botany, studies how plants respond to heat. His findings challenge…

Evolution, evolution, evolution: How evolution got so good at evolving

Evolution, evolution, evolution: How evolution got so good at evolving

The field of evolution examines how organisms adapt to their environments over generations, but what about the evolution of evolution itself? Researchers have long questioned why biological populations are so good at exploiting their environments—a trait called “evolvability.” Think, for example, of antimicrobial resistance and the speed with which new viral pathogens change and are…

Why Earthworms, Ants, and Termites Matter for Climate Health

Why Earthworms, Ants, and Termites Matter for Climate Health

A new Nature publication shows how soil invertebrates influence the world beneath our feet and thus also ecosystem services worldwide. Since the Industrial Revolution, global changes have led to a decline in biodiversity. To address these changes, it is crucial to understand what constitutes healthy ecosystems – and how to protect and build them. A…

Desertification and Climate Change: What’s the Link?

Desertification and Climate Change: What’s the Link?

Around the world, huge swathes of fertile land are turning into arid wastelands at alarming rates, threatening ecosystems, agriculture, and humanity. This process is known as desertification, and it is closely linked to the effects of climate change.  Desertification is accelerating due to rising temperatures, erratic weather patterns, and human activities. The consequences of desertification…

Water scarcity poses risk to Mediterranean marine life and economy

Water scarcity poses risk to Mediterranean marine life and economy

There is a critical link between reduced river flow into the Mediterranean and the health of the Mediterranean marine ecosystems. New research underscores the urgency of integrating water resource management to properly safeguard the rich biodiversity of seas and ocean and the economies it supports. Climate change impacts such as more frequent and more severe…

Scientists discover unique microbes in Amazonian peatlands that could influence climate change

Scientists discover unique microbes in Amazonian peatlands that could influence climate change

Complex organisms, thousands of times smaller than a grain of sand, can shape massive ecosystems and influence the fate of Earth’s climate, according to a new study. Researchers from Arizona State University, along with their colleagues from the National University of the Peruvian Amazon, have identified an unknown family of microbes uniquely adapted to the…

Study shows plants are more likely to be ‘eavesdroppers’ than altruists when tapping into underground networks

Study shows plants are more likely to be ‘eavesdroppers’ than altruists when tapping into underground networks

A new study led by the University of Oxford has used a modelling approach to show that it is unlikely that plants would evolve to warn other plants of impending attack. Instead of using their communication networks to transmit warning signals, the findings suggest it is more likely that plants ‘eavesdrop’ on their neighbours. The…

Flies are more vulnerable to climate change than bees

Flies are more vulnerable to climate change than bees

Despite their reputation as buzzing nuisances, flies serve a critical role as some of the Earth’s most prolific pollinators. A new study led by Penn State scientists suggests that flies are increasingly at risk due to rising global temperatures. An international team of researchers examined the heat tolerance of various bee and fly species in…
