Dendrochronology on drowning shrubs in Arctic tundra (can be minor thesis project)
Shrub expansion is widely observed in the Arctic and is related to climate warming. However, at our field site in Siberian tundra we observe local drowning of low shrub species Betula nana (dwarf birch). Permafrost thawing can tri ...

Modelling vegetation succession and the carbon balance of an Arctic tundra ecosystem
Arctic tundra ecosystems are changing rapidly in response to climate warming during the past decades. At our field site in Siberian tundra we observed that increased permafrost thawing triggered a feedback loop causing collapse of ...

MSc thesis or internship: Drainage impact on greenhouse gas emissions from boreal peatland forests in northern Sweden
About 1.5 million hectares of Swedish peatlands have been drained and afforested during the past century to increase forest biomass production. However, serious concern has been raised that these drained peatlands act as major gre ...

MSc thesis or internship: resilience or constancy of peatland microtopography in response to climate
Peatlands play a key role in the global carbon cycle as they are sinks for atmospheric carbon dioxide but can also be sources for greenhouse gas methane. To understand how peatland carbon fluxes will respond to climate change, it ...

MSc thesis/internship: Can restoration of native agricultural landscape features help New Zealand's farmers and pollinators
Despite agricultural intensification, New Zealand crops are often visited by wild bee and non-bee pollinating species proven to provide pollination services. However, their abundances and distributions currently make them unreliab ...

Internship bij Unie van Bosgroepen: Aminozuurtekorten en Calciumgebrek; de rups als schakel tussen boom en vogel
Inleiding De verzuring van eikenbossen op zandgronden heeft niet alleen directe gevolgen voor de vegetatie, maar veroorzaakt ook problemen hogerop in de voedselketen. Uit onderzoek is gebleken dat een verstoorde nutri�ntenbalans ...

Remote sensing of vegetation succession in an Arctic tundra ecosystem
Arctic tundra ecosystems are subject to accelerated global warming, with warming rates twice as fast as the global average. This may trigger thawing of permafrost and release of permafrost carbon reserves. Vegetation development i ...

Thesis or internship: Optimising quality of Marsh Gentian to facilitate reintroduction of endangered Alcon Blue Butterfly
The Alcon blue butterfly has almost gone extinct in the Netherlands. There is urgent need to strengthen existing populations and perhaps reintroduce the butterfly to suitable new locations. One of the keys to success is to optimis ...
