Накратко на български
Еволюцията на тревните екосистеми се проследява чрез анализ на фосили и генетични данни за семействата на тревите и маргаритките. Това помага да се разбере как миналите климатични промени са повлияли на видовете, за да се предвидят бъдещи сценарии при промяна на околната среда.

The evolution of the Grassland biome: exploring past events to predict future scenarios
Knowledge of the evolution of the grassland biome throughout the Earth's environmental history is important for the reconstruction of links between diversification/extinctions events and climate. Biomes are now being impacted by anthropogenic environmental change on an unprecedented scale, and one mean of understanding how component species will react is to study the effects of past environmental changes. Hence, understanding the evolutionary history of grassland ecosystems in the context of past biotic and abiotic changes is relevant to the way we will manage them under future environmental change. A new perspective on the history of the grassland biome was approached in the present project for the first time using key developments in palaeontology and molecular phylogenetics. GRASSLANDS aimed at understanding the timing and nature of grasslands' most important components, the grass (Poaceae) and daisy (Asteraceae) families, through the combination of fossil data, molecular phylogenetics and computational approaches. We found evidence to support a simultaneous taxonomic radiation of daisies and grasses during the most pronounced drop in atmospheric CO2, during the late Oligocene. The potential contribution of GRASSLANDS to our understanding of the evolutionary history of these families and grassland ecosystems in general is significant and will certainly provide new insights into the rise of flowering plants as the dominant components of almost every terrestrial ecosystems.

Hence, understanding the evolutionary history of grassland ecosystems in the context of past biotic and abiotic changes is relevant to the way we will manage them under future environmental change. A new perspective on the history of the grassland biome is beginning to emerge from key developments in palaeontology and molecular phylogenetics that will be integrated interdisciplinary and multidisciplinary in the present project for the first time.
