Strawberries were smaller when bees ingested pesticides

Published 19 September 2022 Photo: Albin Belsing. Solitary bees that ingested the pesticide clothianidin when foraging from rapeseed flowers became slower. In addition, the strawberries pollinated by these bees were smaller. This is shown by a new study from Lund University in Sweden. Strawberries are known to become bigger if bees have visited their flowers, but how strawberry growth is affected

Mysterious ripples in the Milky Way were caused by a passing dwarf galaxy

Published 26 September 2022 Illustration: NASA JPL-Caltech R. Hurt (SSC Caltech). Using data from the Gaia space telescope, a team led by researchers at Lund University in Sweden has shown that large parts of the Milky Way's outer disk vibrate. The ripples are caused by a dwarf galaxy, now seen in the constellation Sagittarius, that shook our galaxy as it passed by hundreds of millions of years ag

Less bird diversity in city forests

Published 30 September 2022 Photo: Tariq Sulemani/Istockphoto. A new study led by Lund University in Sweden shows that cities negatively affect the diversity of birds. There are significantly fewer bird species in urban forests compared with forests in the countryside - even if the forest areas are of the same quality. The researchers examined 459 natural woodlands located in or near 32 cities in

Study uncovers widespread and ongoing clearcutting of Swedish old forests

Published 9 November 2022 Photo: Ulrika Ervander. Almost one fourth of Sweden’s last unprotected old-growth forest was logged between 2003 and 2019. At this rate, all of these ecologically unique and valuable forests will be lost in about 50 years. These findings add to the growing body of evidence for widespread cryptic forest degradation across the global north. A small fraction of Sweden’s fore

Researchers take first step towards controlling photosynthesis using mirrors

Published 5 January 2023 The researchers used ultrafast laser spectroscopy. Photo: Pavel Chabera. With the help of mirrors, placed only a few hundred nanometers apart, a research team has managed to use light more efficiently. The finding could eventually be useful for controlling solar energy conversion during photosynthesis, or other reactions driven by light. For example, one application could

Feathered robotic wing paves way for flapping drones

Published 19 January 2023 Christoffer Johansson with the robotic wing. Photo: Anders Örtegren. Birds fly more efficiently by folding their wings during the upstroke, according to a recent study led by Lund University in Sweden. The results could mean that wing-folding is the next step in increasing the propulsive and aerodynamic efficiency of flapping drones. Even the precursors to birds – extinct

Stress may trigger male defence against predators

Published 24 January 2023 Photo: Jörgen Wiklund. Only males among the fish species crucian carp have developed a strategy to protect themselves from hungry predators, according to a new study from Lund University in Sweden. The explanation could lie in that the surrounding environment affects the stress system in males and females differently. Some animals have evolved the ability to swiftly chang

Genes decide the willow warbler’s migration routes

Published 6 February 2023 Photo: Harald Ris. Since antiquity, humans have been fascinated by birds’ intercontinental migratory journeys. A new study from Lund University in Sweden shows that two areas in their genome decide whether a willow warbler flies across the Iberian Peninsula to western Africa, or across the Balkans to eastern and southern Africa. Researchers have long known that the behavi

Urban birds prefer native trees

Published 10 February 2023 Urban great tits prefer native trees for breeding. Photo: Caroline Isaksson. Small passerine birds, such as blue and great tits, avoid breeding in urban areas where there are many non-native trees. Chicks also weigh less the more non-native trees there are in the vicinity of the nest. This is shown in a long-term study from Lund University, Sweden. City trees contribute

Bird feeding helps small birds fight infection

Published 19 April 2023 Photo: Johan Nilsson. Seeds and fat balls do more than just fill small birds’ stomachs. New research from Lund University in Sweden shows that feeding during the wintertime causes birds to be healthier, since they do not have to expend as much energy fighting infections. A small change in body temperature can be fatal for humans. Small birds, meanwhile, lower their body tem
