Casey Hall is a postdoctoral researcher at The Hawkesbury Institute for the Environment, Western Sydney University looking at plant defence against insects in a changing climate. In this Insight, she talks about her erecent paper Elevated atmospheric CO₂ suppresses jasmonate and silicon‐based defences without affecting herbivores.

In this Insight, Rafael Dudeque Zenni talks about his recent research looking at how co-occurring invasive species join forces for increased and persistent impact on the ecosystem and why the the Cerrado of Brazil was the perfect place for this experiment.

Frédéric Dulude-de Broin is a wildlife ecologist interested in understanding how predation risk influences individual life-history decisions, affects population dynamic and shapes ecological communities. Frédéric recently completed a master’s degree on the impact of non-consumptive effects of predation on mountain goat reproduction. He is now starting a PhD at Laval University (Québec, Canada) on the role of predation as a driver of arctic terrestrial biodiversity. Here, he discusses his paper “Predation risk and mountain goat reproduction: Evidence for stress-induced breeding suppression in a wild ungulate.”
