The warm climates ofthe Pliocene Epoch (5.33–2.56 million years ago) may be the best past analog for future warmingon Earth: atmospheric CO2 levels were similar to those already reached today (~400 ppmv ...

Forskningsprojekt från 2016-01-01 till 2019-12-31

The adaptation of the tetrapods to a life on land was one of the greatest steps in vertebrate evolution. Several fish groups have attempted to colonise the terrestrial environment but only tetrapods were ...

Forskningsprojekt från 2019-01-01 till 2022-12-31

Exceptionally well-preserved remains of a large theropod dinosaur have recently been found in Skåne. Outstanding details of the bones are visible with the naked eye but does that mean there is a potential ...

Forskningsprojekt från 2021-01-01 till 2024-12-31

This project partners two of Scandinavia’s leading natural history museums to investigate ancient polar ecosystems and pioneer fossil geoheritage in the Arctic. The beginning of the Age of Dinosaurs was ...

Forskningsprojekt från 2013-01-01 till 2015-12-31

The project objective is to reveal the biological affinities of organic-walled microfossils, which presumably represented phytoplankton from the Proterozoic and Cambrian times, through phenotypic studies ...

Forskningsprojekt från 2012-01-01 till 2014-12-31

Current global warming, associated with the rapid release of CO2 by burning of fossil fuels, impacts ecosystems both on land and in the ocean, most notably in polar regions. Marine phytoplankton play a ...

Forskningsprojekt från 2016-11-25 till 2021-04-24

Syfte och mål: FIBREM fokuserar på så kallade ´fiberbankar´. Dessa förorenade sediment finns längs den svenska Norrlandskusten och är orsakade av oreglerade utsläpp från gammal pappers- och massaindustri ...

Forskningsprojekt från 2012-01-01 till 2013-12-31

The proposed project will investigate the diversity, distribution and phylogeny of organophosphatic brachiopods (subphylum Linguliformea) during the Cambrian. It will focus on: 1) the study and comparison ...

Forskningsprojekt från 2015-01-01 till 2018-12-31

Oil is an essential part of modern society and concerns have been raised about future conventional oil supply, turning hope towards unconventional oil. Predictions of future oil production tend to diverge ...

Forskningsprojekt från 2013-01-01 till 2015-12-31

Inland water ecosystems have been recently recognized as important components in the global carbon cycle. Large amounts of carbon are emitted as green house gasses (CO2 and CH4) or stored in sediments ...

Forskningsprojekt från 2021-01-01 till 2024-12-31

Following billions of years of microbial life, the transition to a world of complex animals between 580 and 541 Ma marks a fundamental milestone of evolution. Despite its significance, how this transition ...

Forskningsprojekt från 2019-01-01 till 2022-12-31

This project aims to reassess the phylogeny of Cambrian organophosphatic lophotrochozoans by comparing biomarker composition – a powerful new innovative approach to interrogate Cambrian fossils. All organisms ...

Forskningsprojekt från 2018-01-01 till 2021-12-31

Atmospheric mineral dust not only drives climate change, but also responds to climate itself, forming a complex feedback for which the triggers of change are poorly known. Here we test whether the initial ...

Forskningsprojekt från 2018-01-01 till 2018-01-09

Kvicksilver (Hg) ackumuleras i som monometylkvicksilver (MMeHg) i marina födovävar till koncentrationer som utgör en risk för människors och djurs hälsa. Det är idag okänt om framtida förändringar i de ...

Forskningsprojekt från 2019-12-01 till 2023-11-30

The terrestrialisation of tetrapods (land vertebrates) was a crucial evolutionary event, a key step in the emergence of the terrestrial ecosystem and our own ancestry. It is also an excellent example of ...

Forskningsprojekt från 2020-12-01 till 2024-11-30

The origin of tetrapods is poorly understood. The oldest trackways are much older than the oldest body fossils, and while most Devonian tetrapod fossils are from Laurussia, the tetrapod lineage probably ...

Forskningsprojekt från 2018-01-01 till 2021-12-31

Precise in situ measurements of nickel isotopes in fossilized microorganisms holds great potential for differentiation between non-biologic and biologic microstructures in rocks. Living organisms scavenge ...

Forskningsprojekt från 2015-01-01 till 2018-12-31

This project aims to study oxygen isotopic composition of living and fossil shark teeth, to determine their reliability as a geochemical tool to explore ecology, environment and climatic changes of the ...

Forskningsprojekt från 2014-01-01 till 2016-12-31

Vi kommer att utveckla nya metoder för att bedöma risken för spridning av starkt förorenade sediment, sk fiber bankar, som ligger på grunda bottnar längs den svenska kusten och identifiera de områden som ...

Forskningsprojekt från 2015-01-01 till 2018-12-31

The stability and degradation of organic matter (OM) is a core process in the global carbon cycle and other elemental cycles, and hence receive considerable scientific interest. The research community ...
