Long-term organic farming fosters below and aboveground biota: Implications for soil quality, biological control and productivity
Organic farming may contribute substantially to future agricultural production worldwide by improving soil quality and pest control, thereby reducing environmental impacts of conventional farming. WeExpand
Protozoa and plant growth: the microbial loop in soil revisited.
All nutrients that plants absorb have to pass a region of intense interactions between roots, microorganisms and animals, termed the rhizosphere. Plants allocate a great portion of theirExpand
Bottom-up effects of plant diversity on multitrophic interactions in a biodiversity experiment
Biodiversity is rapidly declining, and this may negatively affect ecosystem processes, including economically important ecosystem services. Previous studies have shown that biodiversity has positiveExpand
Leaf endophytes affect mycorrhizal status and growth of co‐infected and neighbouring plants
Summary 1Fungal leaf endophytes and arbuscular mycorrhizal (AM) fungi are common constituents of natural grasslands. The simultaneous presence of these two grass plant symbionts is highly probable.Expand
Slowing ageing by design: the rise of NAD+ and sirtuin-activating compounds
The sirtuins (SIRT1–7) are a family of nicotinamide adenine dinucleotide (NAD+)-dependent deacylases with remarkable abilities to prevent diseases and even reverse aspects of ageing. Mice engineeredExpand
SIRT1 suppresses the epithelial-to-mesenchymal transition in cancer metastasis and organ fibrosis.
The epithelial-to-mesenchymal transition (EMT) is important for the development of cancer metastases and organ fibrosis, conditions prevalent in aging. Because sirtuins affect the pathology of aging,Expand
Neuronal SIRT1 regulates endocrine and behavioral responses to calorie restriction.
Mammalian life span can be extended by both calorie restriction (CR) and mutations that diminish somatotropic signaling. Sirt1 is a mediator of many effects of CR in mammals, but any role inExpand
Impacts of Soil Faunal Community Composition on Model Grassland Ecosystems
Human impacts, including global change, may alter the composition of soil faunal communities, but consequences for ecosystem functioning are poorly understood. We constructed model grassland systemsExpand
Rhizosphere fauna: the functional and structural diversity of intimate interactions of soil fauna with plant roots
For decades, the term “rhizosphere fauna” has been used as a synonym to denote agricultural pests among root herbivores, mainly nematodes and insect larvae. We want to break with this constrictiveExpand
Environmental Factors Affect Acidobacterial Communities below the Subgroup Level in Grassland and Forest Soils
ABSTRACT In soil, Acidobacteria constitute on average 20% of all bacteria, are highly diverse, and are physiologically active in situ. However, their individual functions and interactions with higherExpand
