Herstel van de natuur op uitgeputte landbouwgrond en in natuurgebieden verloopt moeizaam. ‘Bodemtransplantatie’ kan mogelijk uitkomst bieden. Dat betoogt Martijn Bezemer, hoogleraar Ecologie van Plant-Microbe-Insect interacties. Oratie op 18 december.

Muziek van een composteerbare cello, foto’s en geurtjes van schimmels en een geweven wandkleed. Het zijn een aantal voorbeelden uit Super Organism, het kunstproject van Suzette Bousema waarin je de ondergrondse schimmelwereld met al je zintuigen kunt beleven. Leids milieuwetenschapper Nadia Soudzolovskaia…

The majority (80%) of e-waste generated globally are recycled informally in developing countries.

Elk onderdeel van de kringloop op een melkveebedrijf heeft een specifieke bacterie- en schimmelsamenstelling. Dat ontdekten de Leidse postdoc onderzoeker Sofia Gomes en haar begeleiders Nadia Soudzilovskaia en Peter van Bodegom in samenwerking met het Louis Bolk instituut en Naturalis Biodiversity Centre.…

Gisteren verscheen er een artikel in Biznews over het watertekort in California. David Zetland, universitair docent aan het Leiden University College The Hague, gaf zijn mening over dit probleem.

Nicotinamide adenine dinucleotide (NAD+) is the substrate used for the introduction of the ubiquitous and highly dynamic PTM in which either one or multiple adenosine diphosphate ribose (ADPr) moieties are covalently attached to a nucleophilic side chain of an specific amino acid in the target protein…

Antibiotic-resistant bacteria pose a major health threat. Addressing this challenge requires among others the development of new antibacterial compounds. The research described in this thesis focuses on discovering novel antibiotics from soil bacteria, specifically Streptomyces and Paenibacillus.Despite…

Vooral neerslag en bodemzuurgraad bepalen welke microben in een bepaalde habitat overleven en welke niet. Deze kennis is van belang om de biodiversiteit in stand te houden. Leidse milieukundigen werkten mee aan het onderzoek. Publicatie in Nature op 1 augustus.

Do e-waste workers display enhanced effects of adverse health effects due to informal e-waste processing in Nigeria? Is there a difference between the health outcomes of the exposed and the control groups? Are there difference in health effects within and between job groups (collectors, dismantlers,…

Sewer pipes are an essential infrastructure in modern society and their proper operation is important for public health. To keep sewer pipes operational as much as possible, periodical inspections for defects are performed.

How can we quantify the density of species within a community through environmental DNA concentrations?

The book ‘Bestrijdingsmiddelen en Milieu' gives a transparent overview of facts and figures concerning pesticide use in the Netherlands and the impact of pesticides on the environment.

De afdeling Environmental Biology (CML-EB) houdt zich bezig met vraagstukken rondom biodiversiteit en natuurlijke hulpbronnen op het platteland in westerse en niet-westerse gebieden.

Food security is challenged by a growing global population and by climate change. Drought and soil salinity are considered the most important ones that inhibit crop yield and distribution. Worryingly, climate change is predicted to increase not only their frequency and severity, but also their co-occurrence,…

Mycorrhizas are symbiotic associations between soil fungi and most plant species.

The thesis describes terrestrial field trials aimed to detect side-effects of pesticides within the framework of pesticide registration procedures. Field trials were developed using vascular plants Brassica napus and Poa annua, caterpillars Pieris brassicae and effects on decomposition were studied…

Can we provide the Dutch government with an integrative framework, wherein the various policies can be placed and the need for further measures can be identified?

Plants are colonized by an astounding number of microorganisms that can provide different life-support functions, including nutrient acquisition and protection against (a)biotic stresses like drought or pathogen attack.

My PhD thesis investigates the ecological significance of resistance against drought-induced air bubble formation inside the water conduits of plants (embolism), and the plasticity and functional aspects of stem anatomical traits in woody and herbaceous species.
