Livet i luften – så navigerar djuren mellan himlens våningsplan

Fåglar, fladdermöss och insekter delar upp luften i olika trafikleder. Ny forskning från Lunds universitet visar att atmosfären fungerar som ett eget ekosystem med komplexa ekologiska processer som påverkar hur djur rör sig mellan olika höjdnivåer. Vi ser ofta på luften som tom – men i själva verket är den full av liv. I en ny vetenskaplig artikel introducerar forskare i Lund, Nederländerna och US

Fler blomrika livsmiljöer behövs för pollinatörer i jordbrukslandskapet

Pollinatörer som bin, humlor och fjärilar har för lite livsmiljöer och dessa är dessutom ofta av otillräcklig kvalitet. En ny studie av forskare från mer än 20 lärosäten – däribland Biologiska institutionen och CEC vid Lunds universitet – visar att dessa insekter kan dra nytta av att öka arealen av deras livsmiljöer betydligt mer än vad som idag föreskrivs i EU:s strategi för biologisk mångfald. I

Varmare vårar fördubblar spridning av fågelmalaria

I en unik långtidsstudie, där forskare studerat samma population blåmesar under 30 års tid, visar resultaten att stigande vårtemperaturer har fördubblat förekomsten av fågelmalaria i södra Sverige. Varje år har forskare från Lunds universitet samlat in prover från hundratals blåmesar ur en och samma population i ett lokalt häckningsområde utanför Lund. Detta har gett en detaljerad bild av utveckli

Hundars utseendemässiga mångfald är tusentals år äldre än vad vi trott

Vi brukar härleda dagens zoologiska cirkus av hundraser till viktorianska gentlemen med en faiblesse för selektiv avel. Men sanningen är äldre. En internationell studie visar att hundarnas formrikedom tog fart redan för 11 000 år sedan – långt innan 1800-talets kennelklubbar. Titta på dagens hundar: den näpna chihuahuan som mest liknar ett ögonpar med päls, den storslagna grand danoisen som nästan

Försvarets luftprover avslöjar klimatförändringar

Genom dna-analyser av gamla luftprover kan forskare i Lund visa att de nordliga mossornas sporspridning har flyttats fram flera veckor under de senaste 35 åren. Resultaten speglar hur snabbt naturens kalender ställs om i takt med ett varmare klimat. – Proverna har visat sig utgöra ett oväntat, helt unikt och mycket spännande arkiv över dna från biologiska luftspridda partiklar, säger Nils Cronberg

Ny teknik avslöjar flyttfåglarnas förbluffande flygprecision

Törnskator flyger tusentals kilometer till Afrika – och gör det med förbluffande precision. Med hjälp av ny teknik har forskare i Lund lyckats följa fåglarnas resor i detalj. Det visar sig att de kan ha ett mer komplext, genetiskt flyttprogram än forskarna tidigare kunnat visa. – Vi kan nu i realtid följa var fågeln är under året, hur den har kommit dit och exakt hur lång tid det tog. Varje fågel

Honungsbin tränger undan humlor – även på blomrika ljunghedar

När sensommarsolen faller över irländska Wicklow Mountains blir sluttningarna lila av blommande ljung. Honungsbina flyttas ut till hedarna för den eftertraktade ljunghonungen – men deras närvaro påverkar de vilda humlorna. Ett svensk-irländskt forskarteam visar i en ny studie att vilda humlor både ändrar beteende och är mindre i storlek när antalet bikupor ökar. Forskarna jämförde platser med allt

Rare pattern observed in migrating common swifts

Compared with other migratory birds, the common swift follows a very unusual pattern when it migrates from the breeding areas in Europe to its wintering locations south of the Sahara. This is what researchers have observed in a major eleven-year international study of the birds. “Our study is very significant for understanding how organisms, in this case the common swift, can migrate from one part

SEK 22,9 million for holistic approach on migratory birds

Professor Anders Hedenström receives SEK 22,9 million from Knut and Alice Wallenberg Foundation. Together with his colleagues Susanne Åkesson and Christoffer Johansson he will take a holistic approach to the factors that affect migratory birds and their flight from one part of the world to another. The project runs over a 5-year period. For birds, flying takes a lot of energy. Therefore, it is ext

High temperatures threaten the survival of insects

Insects have difficulties handling the higher temperatures brought on by climate change, and might risk overheating. The ability to reproduce is also strongly affected by rising temperatures, even in northern areas of the world, according to a new study from Lund University in Sweden. Insects cannot regulate their own body temperature, which is instead strongly influenced by the temperature in the

Christmas goodies for birds

A lot of people feed birds in the winter, but what is good for them and what is not? Andreas Nord, bird researcher at the Department of Biology in Lund knows the answer. “Fat is a lot better than crumbs from bread, pastry and buns. Fat is energy, bread is empty calories,” he says.Saffron is a popular “Christmas spice” for baking. For quite some time there have been warnings on social media about f

Butterfly wing clap explains mystery of flight

The fluttery flight of butterflies has so far been somewhat of a mystery to researchers, given their unusually large and broad wings relative to their body size. Now researchers at Lund University in Sweden have studied the aerodynamics of butterflies in a wind tunnel. The results suggest that butterflies use a highly effective clap technique, therefore making use of their unique wings. This helps

Soldiers, snakes and marathon runners in the hidden world of fungi

Researchers at Lund University in Sweden have discovered the individual traits of fungi, and how their hyphae – that is, the fungal threads that grow in soil - behave very differently as they navigate through the earth’s microscopic labyrinths. The study was performed in a lab environment, and the underground system constructed synthetically from silicone. Using a microscope, researchers were able

Ostriches challenged by temperature fluctuations

The world's largest bird, the ostrich, has problems reproducing when the temperature deviates by 5 degrees or more from the ideal temperature of 20 °C. The research, from Lund University in Sweden, is published in Nature Communications. The results show that the females lay up to 40 per cent fewer eggs if the temperature has fluctuated in the days before laying eggs. Both male and female productio

Why overfishing leads to smaller cod

Overfishing, hunting and intensive agriculture and forestry can sometimes contribute to plants and animals becoming endangered. New research from Lund University in Sweden and University of Toronto can now show why this leads to entire populations becoming smaller in size, as well as reproducing earlier. The study is published in the journal PNAS. Researchers from Lund and Toronto are behind the s

Breakthrough in the fight against spruce bark beetles

For the first time, a research team led by Lund University in Sweden has mapped out exactly what happens when spruce bark beetles use their sense of smell to find trees and partners to reproduce with. The hope is that the results will lead to better pest control and protection of the forest in the future. The Eurasian spruce bark beetle uses its sense of smell to locate trees and partners. The odo

Bird parents that receive help live longer

Long life is common among bird parents that get help with childcare. This finding comes from researchers at the universities of Lund and Oxford who reviewed data from more than 9,000 studies. Being a parent can be tough. In general, animals that care for many offspring die young, at least in species where parents are not helped by others. However, in some species things are different and parents r

A warmer climate is making the world’s most common bumblebee even more common

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
