New study highlights need to address risk of continued global warming after net zero

by Liad Hollender, Frontiers science writer Image: Shutterstock.com The UN Climate Panel’s latest best estimate is that global warming will end once we reach net zero CO2 emissions – but a study in Frontiers in Science warns significant warming could still occur. Researchers including those from Imperial College London and University of Exeter assess factors controlling global temperatures post ‘net zero’ and offer a pioneering framework for better estimating climate change risks. These risks must inform climate mitigation and adaptation policies to protect future generations.  From scorching heatwaves to torrential downpours and devastating storms, the disastrous effects of global warming are sweeping across the world. Being the predicted outcome of burning fossil fuels, our best and only plan to limit warming is to reduce CO2 emissions from human activities to ‘net zero’ – where the amount of CO2 we emit into the atmosphere is equal to the amount we remove from it. To keep within the 1.5°C limit of the 2015 Paris Agreement, this needs to happen as soon as possible.   Though the scientific community’s current best estimate from models is that global warming will stop at net zero, an article published in Frontiers in Science raises a red flag.  […]

Forests with multiple tree species are 70% more effective as carbon sinks than monoculture forests

by Deborah Pirchner, Frontiers science writer Image: Shutterstock.com Forests are excellent at absorbing and storing carbon and can play a role in meeting global net zero targets. As more countries commit to forest creation, but mainly plant single species forests, an international team of researchers has examined how carbon stocks in mixed forests and monocultures compare. They found that mixed forests store more carbon, and that out of the forests assessed those with four species had the highest carbon stocks relative to monocultures. To slow the effects of climate change, conserve biodiversity, and meet the sustainable development goals, replanting trees is vital. Restored forests store carbon within the forest’s soil, shrubs, and trees. Mixed forests are especially effective at carbon storage, as different species with complementary traits can increase overall carbon storage. Compared to single-species forests, mixed forests are also more resilient to pests, diseases, and climatic disturbances, which increases their long-term carbon storage potential. The delivery of other ecosystem services is also greater in mixed species forests, and they support higher levels of biodiversity. Although the benefits of diverse forest systems are well known, many countries’ restoration commitments are focused on establishing monoculture plantations. Given this practice, an international […]

Who will profit when territories of Europe’s predators overlap? Here are five Frontiers articles you won’t want to miss

by Deborah Pirchner, Frontiers science writer Image: Shutterstock.com At Frontiers, we bring some of the world’s best research to a global audience. But with tens of thousands of articles published each year, it’s impossible to cover all of them. Here are just five amazing papers you may have missed. Carnivore territories might soon overlap – and some species profit more than others Some of Europe’s large carnivore populations, including jackals and lynxes, are growing and expanding their territories. The golden jackal, a wolf-like generalist that once occupied only the Balkan area, is currently expanding its territory. At the same time, the Eurasian lynx, a specialized predator previously hunted close to extinction, is slowly recovering. Writing in Frontiers in Ecology and Evolution, researchers have now modeled jackal and lynx distribution in Europe for current and future scenarios. Currently, it is estimated that the overlap of jackal and lynx territories is 13%. This overlap is likely to increase, given both species’ expansion. The researchers’ findings showed that both predators expanding their territories, leading to a dynamic where they coexist for the first time, may favor one species and threaten the other: Their predictions show an increase in habitat suitability for the golden […]

Caution, ocelot crossing: special wildlife exits on busy roads help protect endangered cat

By Mischa Dijkstra, Frontiers science writer Texas ocelot, Leopardus pardalis albescens. Image credit: Kline Lab, University of Texas Rio Grande Valley Traffic collisions are a major cause of death of endangered Texas ocelots. Researchers have now shown that recently designed wildlife exits, meant to allow ocelots to leave highways surrounded by fences, function as they are designed to do. 10 mammal species apart from ocelots learned to use them correctly. The authors concluded that these exits are a useful conservation measure in Texas, not only for ocelots. The Texas ocelot (Leopardus pardalis albescens) is endangered due to historic hunting, habitat loss, inbreeding, and traffic collisions. Today, only between 50 and 80 ocelots remain in the US, exclusively in Willacy and Cameron counties in southern Texas. These two populations are isolated from the larger one in northwestern Mexico by highways and urban development. “Here we show that a range of species, including middle-sized carnivores such as bobcats and coyotes, successfully use wildlife exits, a new type of mitigation structure specifically designed for the US endangered ocelot,” said first author Zarina Sheikh, a former graduate student at the University of Texas Rio Grande Valley, about their new study in Frontiers in Ecology […]
