Накратко на български

Морските безгръбначки отпреди 190-270 милиона години се анализират, за да се разбере кои характеристики са помогнали на някои видове да оцелеят при масовите измирания. Това помага да се разберат ефектите от екстремните климатични промени и тяхното влияние върху планетата днес.

Surviving extinction: traits encouraging survival at times of stress

Understanding the causes of mass extinctions is one of the key issues being addressed in Earth Sciences. These ancient catastrophes record severe environmental changes and help us understand the extreme spectrum of conditions that life on earth has faced and inform us about the effects of extreme climate change that has relevance to our understanding of the present day planet. However, being able to recognise and disentangle the multiple proposed causes of mass extinctions is not easy. Causation has been linked with effects of giant meteorite impact for one mass extinction whereas the majority of the others are linked to large-scale volcanism. The effects of this latter cause include rapid emission of carbon dioxide to the atmosphere and its consequential effects: global warming, ocean acidification and changes in ocean circulation leading to widespread anoxia. The problem is working out the relative importance of these changes and why they lead to extinction. The objectives of this research are to compile a major database on marine invertebrate generic ranges in the interval from 270-190 million years ago at a high temporal resolution and use this to calculate extinction rates through an interval characterised by two mass extinctions and several minor crises. This will allow selectivity of extinction to be evaluated and thus the role of key parameters at times of environmental crisis. Extinction risk is primarily controlled by group and geographic range during times of background extinction and so by comparing this background signal with extinction losses at times of mass extinction, the enhanced risk due to factors unique to this interval will be studied.

Цел на проекта

Understanding the response of marine organisms to future global warming, and associated changes such as acidification and oxygenation, is difficult to evaluate based on modern observations alone. This uncertainty will be addressed by studying the fate of marine organisms during the warmer-than-present climate of the Triassic – an interval marked by several major extinction crises attributed to such factors. A major database of species and genera ranges will be constructed for selected groups showing varying susceptibility to stressors alongside a proxy database of environmental variables. I will assess patterns in this dataset using state-of-the-art subsampling and residual modelling techniques and GIS-based packages to reveal the selective roles of kill factors. By allowing me to work in one of the main mass extinction research centres in Europe, alongside Professor Paul Wignall, the fellowship will allow me to become established as a major international researcher. I will bring complementary taxonomic and geochemical skills to the Leeds, which will greatly contribute to this research group and also strengthen their links with my home institute in China, the major geosciences university at Wuhan, thus placing Europe at the forefront of research on key environmental issues concerning ocean stresses.
