Through phylogenetic analysis based on molecular and morphological characters of selected groups of shrimps in combination with the study of their biogeographical distribution patterns and host-relations, hypothesis on the evolutionary history of these groups are formulated. Special attention is given to marine palaemonid shrimps. These shrimps are living in association with other invertebrates. The co-evolutionary component is studied by means of comparisons between phylogenetic patterns of both shrimps and hosts.

Multiple origins and strong phenotypic convergence in fish-cleaning palaemonid shrimp lineages

Several species of palaemonid shrimps are known to act as fish-cleaning symbionts, with cleaning interactions ranging from dedicated (obligate) to facultative. We confirmed five evolutionarily independent origins of fish cleaning symbioses within the family Palaemonidae based on a phylogenetic analysis and the ancestral state reconstruction of 68 species, including 13 fish-cleaners.

    Crises in Biology: Animal Life from the Late Precambrian to the Emergence of Land Life

    Life in all its diversity evolved in the marine environment. In this course taught at Leiden University and at the Marine Center of the University Marie et Pierre Curie, France, in Roscoff, we teach aspects of the Tree of Life, we focus on the transition from mono-cellular life to animal life conquering the continents in the early Paleozoic, and we address Earth history from the time of the origin of life to the adaptations that made the emergence of land life possible.

    We bring together a multi-disciplinary team of marine biologists, ecologists, physicists and geophysicists, isotope geochemists, paleontologists and geologists to teach a course in geo-biology with special interest in the Tree of Life, the origin of life, and the environments in which life evolved.
