When the snow is gone, it does not take too long before a familiar spring sound reappears - the bumblebee buzz. Since bumblebees are well adapted to cold climates, many of the species are negatively affected by a warmer climate. Researchers at Lund University now ask for the public's help in reporting the first bumblebee queens of the spring, to be able to map how earlier springs affect bumblebees

Many species of bee are threatened by global warming, but not all. The buff-tailed bumblebee is the world’s most common bee and will likely remain that way, as researchers from Lund University have discovered that this species benefits from a warmer climate. Through research into buff-tailed bumblebees collected by amateurs and researchers over a period of 150 years, biologists and climate researc

Boreal peatlands store large amounts of carbon, but warmer and drier conditions caused by climate change may turn these ecosystems into carbon sources. Equipped with drones and thermal cameras Julia Kelly, who recently received her doctorate at the Centre for Environmental and Climate Science (CEC), has studied what factors affect the CO2 fluxes in peatland ecosystems. Boreal forests and peatlands

The forest is currently at the centre of an intense debate. It concerns, in simplified terms, which climate benefits the forest can provide, either by sequestering carbon in standing forest, or by being used to substitute fossil fuels and fossil-intensive materials. In a new literature review from the Centre for Environmental and Climate Science (CEC) at Lund University in Sweden, Markku Rummukain

An international research team has found a new method for predicting entire pollen seasons, something that can help healthcare and allergy sufferers plan to reduce problems. No similar tool has previously been used in the area. The researchers also show that pollen seasons may be 60 per cent more severe in the future due to climate change. For about one in four Swedes, the arrival of spring and su

By changing from action-based to result-based environmental payment, farmers are financially encouraged to implement conservation measures, such as buffer strips and organic farming, where they are most beneficial for the environment and not, as today, where they least disrupt the production. This according to William Sidemo Holm, who recently defended his dissertation on biodiversity and ecosyste

This summer, Lund University doctoral student Sofia Blomqvist will be investigating how pollinating insects such as bumblebees and solitary bees are faring in flower-rich roadside habitats. However, there is one problem: bumblebee nests are very difficult to find. Now she hopes to be able to train Ylle the dog to help her. Sofia Blomqvist’s objective is to repeat a previously criticized scientific

They become smaller as urbanisation increases. Troublesome, according to researcher Helena Hanson, because urban private gardens affect both cities’ biodiversity and human wellbeing by functioning as social green spaces. Now she strikes a blow for gardens in the urban planning. Green spaces, such as parks and allotment gardens, have a major impact on our physical and mental health and wellbeing –

Two Lund University climate scientists, Kimberly Nicholas, who has acted as an observer at two global climate summits, and Markku Rummukainen, Sweden’s IPCC representative, talk about what comes next following the recent IPCC report. What do you view as the next steps following what was concluded in the IPCC report? Kimberly: Something the report makes absolutely clear is that to stop warming, hum

Farming practices that result in higher levels of carbon in agricultural soils could protect both wheat and barley harvests in a future changed climate. This is what emerges from a new study from Lund University in Sweden. However, the practices required are more costly for farmers in the short term, according to the researchers who argue for targeted environmental payments. Ongoing climate change

On October 31st, representatives from across the globe will gather in Glasgow for two weeks to attend the UN climate change conference COP26. Expectations are high following last year's canceled conference, and the IPCC report released in August. As part of the Paris Agreement in 2015, it was decided that all nations would renew their climate pledges or national climate plans, so-called NDCs (Nati

Primitive stoves and diesel engines produce soot particles, besides being bad for your health, have a negative effect on the climate. By affecting the atmosphere’s ability to form cloud droplets and ice particles, soot can dislodge the radiation balance. This according to doctoral student John Falk, who is currently working on his dissertation about cloud droplet and ice particle formation in clou

Lack of habitats and climate change – parameters that scientists know affect the number of pollinators in the world. But exactly how big is the effect and what else contributes to the decline of bees and bumblebees? This has Maria Blasi i Romero tried to find out in her dissertation which will be presented on November 26. A sure sign of spring is the buttery yellow rapeseed fields that every year

The type of tree you plant – whether you choose native or non-native species – is of great significance for insect life in a city, more so than researchers previously thought. This is what emerges from a new study by researchers at Lund University in Sweden, who investigated the parks in the city of Malmö. Trees are crucial to insects, birds and even people in a city. They lower the temperature, p

Scientific advice to decision makers requires transparent scientific assessments, in which communication of uncertainty is important in order to avoid over- or underestimating conclusions. In her dissertation ”Robust analysis of uncertainty in scientific assessments”, doctoral student Ivette Raices Cruz, who recently defended her dissertation at Center for Climate and Environmental Science (CEC),

Increasing attention is being paid to the impact of honey bees on wild bees. In a new report from Lund University in Sweden, researchers observed that honey bees compete with wild bees for flower resources, and that more research and knowledge are needed to create the conditions for coexistence between bee-keeping and the conservation of wild bees in Sweden over the long term. In recent years, the

Scientists at Lund University have discovered for the first time that it is possible to detect insect DNA in the air. Using air from three sites in Sweden, insect DNA from 85 species could be identified. This offers scope for exploring a whole new way to monitor terrestrial biodiversity. These preliminary results was presented at Ecology Across Borders (13th-15th December) via an online poster by

On Monday, the UN’s Intergovernmental Panel on Climate Change (IPCC) published a new report on how climate change is impacting nature and people worldwide, and on the necessity for adaptation. According to the researchers, more than three billion people live in environments that are particularly vulnerable to climate change, and the same applies to many species. The researchers establish that thos
