  1. PhD position: Ecology and Genomics of Phyllosphere Yeasts

    Position
    The phyllosphere - the aerial parts of plants - harbors a rich and diverse microbial community, including bacteria, filamentous fungi, yeasts and viruses. This environment is both harsh and dynamic, exposing microbes to a range of biotic and abiotic stresses (e.g. low nutrient availability, ultraviolet radiation, temperature and humidity oscillations, toxic compound exposure). Yeasts have diverse ways to cope with these conditions and compete with plant pathogens, providing protection. To date, the adaptive traits and competitive mechanisms by which yeasts colonize the phyllosphere remain largely unknown.

  2. PhD position: Marine phytoplankton - virus interactions and species competition

    Position
    As PhD candidate for PHYVIR you will contribute to improving our understanding of the interplay between viruses and their phytoplankton hosts.

  3. Two senior researchers: community ecology & biodiversity in a changing world

    Position
    In the department of Terrestrial Ecology, we study ecosystems on land in a changing world.

    To strengthen our team, we seek to hire two senior researchers working on biodiversity restoration or responses of communities and ecosystem functions to global change, with at least one of the positions focussing on plant or insect community ecology.

  6. PhD position on avian reproductive microbiomes and immunity

    Position
    The PhD position will involve fieldwork on wild birds to collect samples for analysis of microbiomes, immune function, and sperm quality, as well as performing in vitro studies to experimentally validate the impact of bacteria on avian sperm quality and the impact of antimicrobial proteins on bacterial community growth and composition. The position will also involve laboratory work, including processing of microbiome samples, immune assays, analysis of sperm quality, and bacterial culturing.

  7. SPI-Birds Network & Database

    Faciliteit
    NIOO-KNAW
    SPI-Birds Network & Database, or the Studies of Populations of Individuals – Birds, is a grassroots initiative connecting those working on populations of individually-marked breeding birds. SPI-Birds is a metadata registry of individually-marked breeding bird studies and the people involved in these studies, and a central hub for data on individually-marked breeding birds.

  8. Living Lab

    Faciliteit
    Leiden University
    The Living Lab is an outdoor lab, suited for research on the consequences of pollution from pesticides, fertilisers, microplastics, advanced materials and invasive species such as crayfish. It consists of 32 ditches (8 meter length, 50 cml width, 30-60 cm depth)that are allowed to develop natural communities so that actual biodiversity and ecosystem functionality impacts can be assessed. The ditch systems are connected o a watershed that allows natural colonization of organisms into the test ditches (=cosms).

    Besides, it is an important place for education of elementary school pupils to higher education students.

  9. Postdoc: Climate robust landscapes

    Position
    This project will assess the complex interplay of climatic changes, societal responses, and impacts on water quality and biodiversity to develop scenarios for climate robust landscapes.

  10. Impacts of nutrients and climate change on competition in cyanobacterial blooms

    Internship
    This student project will consist of running chemostat experiments with toxic and non-toxic strains of Microcystis aeruginosa and Dolichospermum flos-aquae, two prominent bloom forming species in the Netherlands. The project will include monocultures to characterize the species, as well as competition experiments under different nutrient limitations.
