About me

Hi,

My name is Lisette Lenoir and I am a researcher at SLU. My area of research is soil ecology and I conduct most of my research at the [1]. You may find my personal page on SLU [2].

Research Interests

My research interests are focused on how agriculture, forestry and anthropogenic disturbances affect soil animals such as spiders, ants and earthworms. I am also interested in how soil animals affect processes such as Carbon and Nitrogen cycling in the soil. I have worked with a large array of soil organisms including fungi, decomposing fauna, and arthropod predators in forest soils, grazed grasslands and urban environments. My favorite research animals are ants.

Ants Ants are predators that forage on insects in the canopy. Ants can even forage on soil-dwelling fauna and they can affect soil macrofauna such as spiders and beetles by interference competition. I have carried out studies on how ants affect the abundance and species composition of soil fauna. The effects of ants on soil fauna can change decomposition and nutrient cycling rates in the soil. Ants can change the soil ecosystem also by collecting nest materials, including conifer resin nest, by digging and mixing soil materials and other nest building activities.

I also have studied the effects of grassland management (grazing versus non-grazing and fertilizing versus non-fertilizing) and contamination of toxic substances on the abundances and species composition of ants.

Earthworms in semi-natural grasslands (on-going) Semi-natural grasslands are the result of a long management history. The studies on the effects of grazing often use vascular plants or insects. Earthworms are often considered as key-stone species that have a large impact on soil and can be used as a model organism to investigate the relation between soil properties, soil organisms and plants. I have studied the effects of grazing management on earthworm diversity and earthworm abundance. Grazing may cause soil compaction and decrease of organic materials, especially leaf litter. This may cause changes in earthworm species composition and abundances of epigeic (litter living) and anecic (top-soil living) earthworms may decrease in grazed fields. This may affect germination of plant seeds in grazed fields and thereby determine plant species composition in semi-natural grasslands.

Other soil fauna I have investigated if soil fauna systems are controlled by bottom-up or top-down regulations and if these mechanisms are different in soils with different nutrient status. I also have investigated the effects of forest management, grazing and fertilization management on the relation between soil fauna and C and N mineralization processes.
