Different species of seabirds can coexist on small, isolated islands despite eating the same kind of fish. A researcher at Uppsala University has been involved in developing a mathematical model that can be used to better understand how this ecosystem works.
Seven of the most common forest trees in Europe have been shown to be able to shelter their genetic diversity from major shifts in environmental conditions. This is despite their ranges having shrunk and the number of trees having fallen sharply during ice age cycles. These are the findings of a study jointly led by Uppsala and Helsinki Universities, published in Nature Communications.
To answer this question, Linnaeus collected 643 different plant species that were then fed to horses, cows, pigs, sheep and goats. The results were carefully compiled but not analysed until now, 275 years later, when they are also published by the Linnean Society in London.
On 16 September two Dag Hammarskjöld Lectures will be held in Uppsala. Rena Lee, Singapore’s Ambassador for International Law will talk about ‘From Sea to Shore: Multilateralism and the Value of International Law’. Jan Egeland, Secretary General of the Norwegian Refugee Council, will talk about ‘The Lesson from Hammarskjöld for Conflict Resolution Today’. The lectures are open to the public.
Krill in our northern waters show how key marine species can adapt genetically to cope with climate change. This is the discovery made by researchers at Uppsala University in collaboration with an international research group. According to the researchers, their study, published in Nature Communications, provides important knowledge that can help protect marine ecosystems when the climate changes.
Rabbits have colonised countries worldwide, often with dire economic and ecological consequences, but their secret has before been a mystery. In a new study published in the journal Nature Ecology and Evolution, an international consortium of scientists sequenced the genomes of nearly 300 rabbits from three continents to unveil the key genetic changes that make these animals master colonisers.
Researchers have discovered that bank voles in Skåne, southern Sweden, carry a virus that can cause hemorrhagic fever in humans. This finding was made more than 500 km south of the previously known range. This is revealed in a new study from Uppsala University. The researchers were surprised that such a high proportion of the relatively few voles they caught were actually carrying a hantavirus.
Despite marine sponges being widespread on our planet, their biodiversity and distribution is still poorly known. Even though the Mediterranean Sea is the most explored sea on Earth, a study by Díaz et al. (2024) reveals the presence of new sponge species and new records in unexplored habitats such as underwater caves or mountains around the Balearic Islands.
Increasing access to water in extremely arid parts of sub-Saharan Africa can help nomadic livestock farmers in the short term. However, in the long run it may lead to serious consequences for their livelihoods. This is shown by new research from Uppsala University, published in Nature Climate Change.
Researchers at Uppsala University have studied the relationships between five closely related species of larks that occur in Africa south of the Sahara. They propose that the two species be split into seven. Some of them haven't been observed for decades, so the researchers analysed DNA from museum specimens, some of which were over 100 years old.
An international team of researchers has released a study on contemporary evolutionary change in natural populations. Their study uses one of the largest genomic datasets ever produced for animals in their natural environment, comprising nearly 4,000 Darwin’s finches. The study has revealed the genetic basis of adaptation in this iconic group. The results are published in the journal Science
A major international research project, jointly led by Prof Kerstin Lindblad-Toh at Uppsala University and Broad Institute has surveyed and analysed the genomes of 240 different mammals. The results, now published in 11 articles in the journal Science, show how the genomes of humans and other mammals have developed over the course of evolution.
Researchers at Uppsala University have shown that Scandinavian wolves carry around 100,000 harmful mutations in their genome. As long as the harmful mutations can be compensated by a healthy genetic variant, this does not need to pose a problem. However, as there has been a high level of inbreeding in the wolf population, the occurrence of double harmful variants has increased with each generation
The European robin’s closest relatives are found in tropical Africa. The European robin is therefore not closely related to the Japanese robin, despite their close similarity in appearance. This is confirmed by a new study of the Old World flycatcher family, to which these birds belong. The study comprises 92 per cent of the more than 300 species in this family.
Researchers from Uppsala University and elsewhere have been studying the effect of rising temperatures on the lifespan of pollinating fig wasps. The findings show that the wasps lived much shorter lives at high temperatures, which would make it difficult for them to travel the long distances between the trees they pollinate.
Sverker C Jagers, Professor of Political Science and Director of the Centre for Collective Action Research at the University of Gothenburg, will hold Uppsala University's fifth Zennström Visiting Professorship in Climate Change Leadership. The ten-year visiting professorship, through which a new professor is invited every year or every other year, is funded by an earlier donation to Uppsala Univ
In a study an international team of researchers have identified 28 gene regions that have been particularly important in the evolution of Darwin’s finches. These genetic variants do not represent recent mutations but constitute ancestral genetic variation that has accumulated over time as different species of Darwin’s finches have evolved with striking differences in beak morphology.
Coral species exhibit different temperature tolerances. This is in part due to the composition of their microalgae symbionts. With a new method, researchers from Uppsala University were able to predict how individual microalgae might behave under future temperature stress and identify more tolerant coral symbionts. In combination with forthcoming single cell selection and growth experiments, the
A new study from scientists at Uppsala University shows that it took more than 10 millennia from when the first spruces returned to Sweden after the glacial stage of the last Ice Age until the species became widespread. This sluggish rate of initial dispersal has surprised the researchers, since the spruce might have had good prospects of expanding its range.
Founded in 1477, Uppsala University is the oldest university in Sweden. With more than 50,000 students and 7,500 employees in Uppsala and Visby, we are a broad university with research in social sciences, humanities, technology, natural sciences, medicine and pharmacology. Our mission is to conduct education and research of the highest quality and relevance to society on a long-term basis. Uppsala University is regularly ranked among the world’s top universities.
