Majority of the world's most abundant creatures live in the far north
The first worldwide analysis of soil nematodes reveals that they are most abundant in arctic areas rather than in the tropics. -
Caterpillars retrieve 'voicemail' by eating soil
Leaf-feeding caterpillars greatly enrich their intestinal flora by eating soil. It's even possible to trace the legacy effects of plants that previously grew in that soil through bacteria and fungi in the caterpillars. -
What makes soil, soil? Researchers find hidden clues in DNA
Ever wonder what makes soil, soil? And could soil from the Amazon rainforest really be the same as soil from your garden? Researchers from the University of Manchester and the Netherlands Institute of Ecology (NIOO-KNAW) are using DNA sequencing to unlock the secrets of the world’s soils, and analyse ecological patterns and microbial communities on a global scale. -
Spiders and earthworms overtake woodlice in Dutch gardens
Woodlice have for the first time been dethroned as the most spotted soil animals in Dutch gardens. The third edition of the nationwide Soil Animal Days saw arachnoids seize the top spot, with earthworms a close second. A probable explanation for the shift is the extremely wet weather at the onset of autumn. Fortunately, that didn't stop some 600 enthousiasts from counting the soil animals in their gardens. -
'It depends': soil organic matter doesn't automatically increase crop yield
More organic matter in the soil may be beneficial for the climate, but contrary to what's been assumed it doesn't automatically increase crop yield. The amount is not the only factor, concludes research by NIOO's Stijn van Gils: it also depends on the context. -
Restoring nature the fast way
Restoring nature is not for the impatient: it takes a lot of time before the right plant species establish themselves. But experiments show there's a way to speed up the process, from decades to just a few years. A new website from the Netherlands Institute of Ecology (NIOO-KNAW) tells you everything you need to know. Meanwhile, one of the researchers working on this pioneering approach defended his PhD thesis this week. -
Micro-organisms will help African farmers
Sorghum is the fifth most important cereal in the world. In sub-Saharan Africa, many farmers rely on this grain for food and feed. But Striga, a parasitic weed, can have a devastating impact on crop yield. With an 8-million-dollar grant from the Bill & Melinda Gates Foundation, an international team will now explore the potential of soil microbes to offer crop protection. The Netherlands Institute of Ecology (NIOO-KNAW) is coordinating this 5-year project. -
Why nature restoration takes time: fungi grow 'relationships'
‘Relationships’ in the soil become stronger during the process of nature restoration. Although all major groups of soil life are already present in former agricultural soils, they are not really ‘connected’ at first. These connections need time to (literally) grow, and fungi are the star performers here. A European research team led by the Netherlands Institute of Ecology (NIOO-KNAW) has shown the complete network of soil life for the first time. This Wednesday, the results of the extensive study are published in Nature Communications. -
Sniffing out your dinner in the dark: how miniature predators get their favourite soil bacteria
Tiny predators in the soil can literally sniff out their prey: soil bacteria, which communicate with each other using scent. A team of researchers from the Netherlands Institute of Ecology (NIOO-KNAW) has discovered that these predators - called protists - 'eavesdrop' on the bacteria's communication. It's a discovery that opens up perspectives for agriculture. The results are available online this month in The ISME Journal, from the publishers of Nature. -
Predicting plant-soil feedbacks from plant traits
In nature, plants cannot grow without soil biota such as fungi and bacteria. Successful plants are able to harness positive, growth-promoting soil organisms while avoiding the negative effects of others. Which plant traits can predict these interactions, or the success of a plant? Researchers and plant breeders would like to know. In a paper in the Journal of Ecology of August 24, a team from the Netherlands Institute of Ecology (NIOO-KNAW), Wageningen University and the Universität Leipzig tested exactly this and found thick roots to be a leading trait.
