The Rise and Fall
How long does a species exist? Despite substantial advances in evolutionary biology in the last decade, the answer to this apparently simple question remains largely unknown. In this project we are i) analysing molecular sequences and fossil records to estimate low long species have lasted in the past; ii) identifing which major factors determine rates of species formation (speciation) and disappearance (extinction); and thereby iii) identifying which major taxa and geographical regions have been most affected by climatic changes in the past.

The Past, Present and Future of Neotropical Biodiversity
The American tropics – the Neotropics – comprise more species than any other region on Earth, including thousands of species used as crops, medicines and crafts. Understanding the evolution of this biodiversity and predicting the effects of climate and habitat changes on species losses constitute a major scientific challenge. In this project we are 1) Estimating the rates of historical migration, speciation and extinction among and within all major Neotropical biomes and regions; 2) Testing competing hypotheses of speciation for the two main centres of Neotropical biodiversity: the tropical Andes and Amazonia. To achieve these goals we are developing novel bioinformatic pipelines that may greatly improve our use of biological databases. We are analysing DNA sequences, species occurrences and biotic traits for tens of thousands of plant and animal species.

The Quest for Cinchona –
a Phylogenetic Tale
The objective is to use an iconic historical case to establish the predictive power of phylogenies as a new approach to infer the evolution of biochemical pathways or to select candidate organisms for drug discovery and traditional use. We will focus on Cinchona and relatives, which have been used to prevent and treat Malaria for hundreds of years. Read more here. This project is led by Prof. Nina Rønsted (Natural History Museum of Denmark).

knowme.earth is an Open Sourced software platform for Collaborative Species Identification. It has been used for projects such as the Swedish ”Nyckelpigeförsöket 2018” where schools used the app to do observations of Ladybugs. The pictures will be used to to build Image Recognition of Ladybugs into the app.
