by Angharad Brewer Gillham, Frontiers science writer Image/Shutterstock.com Eating more plant-based dishes is good for your health and good for the planet – but the perception that these dishes are for women and not for men may be stopping some men from choosing plant-based meals. Scientists found that you can present vegan dishes with a masculine framing, altering the perception that these dishes are for women, but changing the perception doesn’t change people’s preferences. Eating more plant-based meals is better for our health and better for the planet. But cultural preferences are significant barriers to reducing meat consumption – especially for men, who are underrepresented among vegans and vegetarians. Studies have found that eating meat is associated with masculinity, and that gender stereotypes label plant-based diets as suitable for women but not men. So is it possible to change the perception of plant-based food with marketing, and convince men to eat more of it? “Men might be less inclined to consume vegan food due to the need to perform gender,” said Alma Scholz, lead author of a new study published in Frontiers in Communication. “However, with vegan food being framed in a masculine way, men might feel less resistance and […]

by Angharad Brewer Gillham, Frontiers science writer Image/Shutterstock Animals’ circadian clocks normally get cues from their environments: light cycles, seasonal food availability, and temperature. If these cues are very different to the ones from the latitudes which they have adapted to, it could disrupt their bodies and behavior, like jet lag in humans. Scientists studying the effect of this possible ‘jet lag’ on giant pandas, which are a vulnerable species and live in zoos worldwide, have shown that pandas housed in different latitudes to their normal range in China are less active, with potentially negative consequences for their welfare. All animals have an internal clock called a circadian clock, which is regulated by cues from their environment — but animals in zoos can be exposed to very different cues from animals in the wild. Since all animals’ circadian clocks are linked to their behavior and physiology, this could be significant to their welfare, which is crucial to maintaining captive populations of animals at high risk of extinction in the wild, like giant pandas. Scientists set out to understand how the ‘jet lag’ of living in latitudes they did not evolve in, and therefore getting cues for their circadian clocks which […]

by Angharad Brewer Gillham, Frontiers science writer Image/Shutterstock. With the changes in conditions caused by the climate crisis, the forests of the Italian Alps and Apennines are set to alter. Many species, including keystone species, will have smaller ranges to grow in. Some others may expand their ranges, possibly helping to maintain forests in the years to come. Scientists now warn that conserving our forests depends on detailed biodiversity modelling. As a result of the climate crisis, future forests may become unrecognizable. Trees that currently make up European woods may no longer be seen — or they may have moved several hundred meters uphill. Scientists writing in Frontiers in Forests and Global Change have mapped the forests of five vulnerable mountain areas in Italy and modelled the future of these fragile ecosystems. “If I imagine my daughter walking with me as an old man, in our mountain forests, I can imagine that we can see the initial stage of a profound change of species,” said Dr Sergio Noce of the Euro-Mediterranean Center on Climate Change Foundation (CMCC). “Like any natural process, time is needed, and forests have times that are totally different from us.” Seeing the wood for the trees […]

by Angharad Brewer Gillham, Frontiers science writer Image/Shutterstock.com We know that microplastic contamination has reached the Arctic, but quantifying the amount that appears on beaches and understanding where it came from is difficult. Scientists asked tourists on Arctic cruises to take part in a program of sample collection while visiting Svalbard and used these samples to identify microplastics that probably originated from ships and fishing net. Tourists acting as citizen scientists have helped a research team detect microplastics on remote Arctic beaches. The global scale of plastic production means that these tiny fragments of plastic are now ubiquitous, and scientists fear that ocean currents will cause plastic to accumulate in the Arctic, damaging ecosystems. But our knowledge of the scale and type of plastic pollution in the Arctic is incomplete. Researchers recruited holidaymakers to carry out sample collection during cruises, hoping to fill in some of the gaps in their knowledge. “Plastic pollution is now ubiquitous. It is found on land and in soil and most rivers of the world,” said Dr Bruno Walther of the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research, author of the study in Frontiers in Environmental Science. “It is even found in […]

by Angharad Brewer Gillham, Frontiers science writer Image courtesy of the Hub for Biotechnology in the Built Environment Scientists have developed mycocrete, a paste made with the root network of fungus called mycelium, as a building material. Injecting this into a knitted textile framework creates a composite material which is stronger and more versatile than previous biomaterials made of fungi and could eventually be used to construct lightweight buildings with low environmental impact. Scientists hoping to reduce the environmental impact of the construction industry have developed a way to grow building materials using knitted molds and the root network of fungi. Although researchers have experimented with similar composites before, the shape and growth constraints of the organic material have made it hard to develop diverse applications that fulfil its potential. Using the knitted molds as a flexible framework or ‘formwork’, the scientists created a composite called ‘mycocrete’ which is stronger and more versatile in terms of shape and form, allowing the scientists to grow lightweight and relatively eco-friendly construction materials. “Our ambition is to transform the look, feel and wellbeing of architectural spaces using mycelium in combination with biobased materials such as wool, sawdust and cellulose,” said Dr Jane Scott […]

Scientists studying three common species of antelope in Namibia found that they generally reduced or changed the timing of activity to cope with heat stress, but the smaller and more active antelopes were most affected. In the future, heat stress could drive significant changes to the animal composition of this habitat. The climate crisis is turning the temperature up all over the world, but in southern Africa, the rise has been particularly concerning. Wild animals dependent on delicate ecosystems which are already dry, so that food and water scarcity limits their ability to cope with increased heat, are at serious risk. Scientists studied the behavior of three different species of antelope with overlapping ranges in Namibia to try to understand how animals of different sizes and behaviors adapt to the heat. “Even the indigenous wildlife, adapted to hot and arid conditions, shows sensitivity to extreme heat,” said Paul Berry of the University of Potsdam, lead author of the study in Frontiers in Ecology and Evolution. “We need to consider the possibility that additional anthropogenic influences […]

by Angharad Brewer Gillham, Frontiers science writer Image/Enric Ballesteros Scientists show that efforts to restore the building blocks of marine ecosystems are paying off, with macroalgae that provide food and shelter for other species bouncing back over 10 years of growth in an underwater seaweed forest in the Mediterranean Sea. Human activity has degraded ecosystems and damaged biodiversity around the world, but ecosystem restoration offers hope for the future. Scientists studying the restoration of underwater seaweed forests which provide other species with food and shelter have found that 10 years of restoration efforts have helped a damaged forest regrow to richness and strength comparable to forests that have never been disturbed. “Macroalgal forests are found along over one-third of the world’s coastlines and underpin entire ecosystems,” said Dr Emma Cebrian of the Centre d’Estudis Avançats de Blanes, corresponding author of the study in Frontiers in Marine Science. “In 2011, a restoration action took place in the Bay of Maó, Menorca, where a macroalga species was reintroduced in the area where it used to thrive. After 10 years, we found that the associated algal species returned to the habitat, and with them, the ecosystem functions they provide.” Under the sea Cebrian […]
