Biodiversity and Litter Decomposition in Terrestrial Ecosystems
▪ Abstract We explore empirical and theoretical evidence for the functional significance of plant-litter diversity and the extraordinary high diversity of decomposer organisms in the process of…

Non‐native invasive earthworms as agents of change in northern temperate forests
Soils of north temperate forests harbor a tremendous diversity of microorganisms and invertebrates, whose distribution and abundance can be substantially altered by earthworm invasion, and invasive earthworms can affect understory plant communities, raising concerns over the loss of rare native herbs.
Organo-mineral associations in temperate soils: Integrating biology, mineralogy, and organic matter chemistry
We summarize progress with respect to (1) different approaches to isolate, extract, and quantify organo-mineral compounds from soils, (2) types of mineral surfaces and associated interactions, (3)…
B and T lymphocyte attenuator regulates T cell activation through interaction with herpesvirus entry mediator
The conservation of the BTLA-HVEM interaction between mouse and human suggests that this system is an important pathway regulating lymphocyte activation and/or homeostasis in the immune response.
Thymic Medullary Epithelial Cell Differentiation, Thymocyte Emigration, and the Control of Autoimmunity Require Lympho–Epithelial Cross Talk via LTβR
It is shown that thymocytes and medullary epithelial cells (MECs) communicate via the lymphotoxin β receptor (LTβR) signaling axis, suggesting an unexpected role for LTβR signaling in central tolerance induction.
Earthworm invasion into previously earthworm-free temperate and boreal forests
The invasion of European earthworms into previously earthworm-free temperate and boreal forests of North America dominated by Acer, Quercus, Betula, Pinus and Populus has provided ample opportunity to observe how earthworms engineer ecosystems.
Consequences of biodiversity loss for litter decomposition across biomes
Reducing the functional diversity of decomposer organisms and plant litter types slowed the cycling of litter carbon and nitrogen, and the emergence of this general mechanism and the coherence of patterns across contrasting terrestrial and aquatic ecosystems suggest that biodiversity loss has consistent consequences for litter decomposition and the Cycling of major elements on broad spatial scales.
Plant diversity increases soil microbial activity and soil carbon storage.

It is shown that higher plant diversity increases rhizosphere carbon inputs into the microbial community resulting in both increased microbial activity and carbon storage, indicating that the increase in carbon storage is mainly limited by the integration of new carbon into soil and less by the decomposition of existing soil carbon.
