How do environmental variables control community composition and organismal growth?

This fundamental question represents the key aspect of my general research interest that addresses lake ecosystem evolution during the past 165 million years. Lakes and temporary wetlands are biodiversity hotspots, but they are also especially sensitive to extinction, as species are unable to migrate freely in response to climate change or other (anthropogenic) influences. Palaeolake environments witnessed major re-organizations during the Cretaceous. I am a key member of a multidisciplinary research group that addresses both micro- and macro-evolutionary questions by investigating faunal communities on single bedding planes and through time. Our investigations target major fossillagerstätten of evolutionary importance, such as the Middle to Late Jurassic Yanliao Biota or the Early Cretaceous Jehol Biota. Specifically, we test whether changes in community composition are related to gradients of environmental variables, such as temperature, oxygen and nutrient availability. To that end, we integrate classic palaeontological methods (field work, fossil identification), ecological data analysis, sedimentology, and biogeochemical methods. My research will, over the coming 5–10 years, provide insights that have the potential to unravel the evolutionary history of the Cretaceous lacustrine faunal turnover that led to modern lake environments.

My ongoing and future research focusses on four key aspects:

(1) Understanding the macro-evolutionary history of Middle Jurassic to Cretaceous lacustrine communities in China (based on excavations)

(2) Investigating how the environment influences morphological phenotypes in fossil spinicaudatan crustaceans, the most abundant faunal component in Mesozoic lakes

(3) Examining whether correlations between biogeochemical data and fossil morphological data are biologically meaningful (rearing experiments)

(4) Assessing modern temporary European wetlands that have been in rapid decline over the past 100 years
