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

Supervisor: P.J.J. Hooykaas

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…

Mycoheterotrophy is a particular mode of life in which plants obtain carbohydrates from their associated fungal partners, instead of by using photosynthesis.

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.

The overall objectives of my thesis are to investigate the dynamics of the sorghum root microbiome and to explore the beneficial effects of the root microbiome on sorghum growth and stress tolerance.

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.

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.

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?

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.

Creating information portals for support of European environmental policy.

The aim of this project was to estimate emissions from lead products-in-use for the past, the present and the future and assess the development of toxicological risks associated with these products.

A management strategy has been developed for field margins to reduce pesticide drift to non-target areas and to promote biodiversity on arable land. To this end, 3 and 6 m wide strips along the edges of winter wheat, sugar beet and potato crops have been left unsprayed with herbicides and insecticides…

Wat zijn de belangrijkste thema's in het uitvoeren van systemen voor bio-energie ?

Promotores: W.T. de Groot, M. Tchuenté, Co-promotor: J.P. Cheylan

Accumulation of metals in economy and environment and its associated risks, within the Netherlands and the EU.

Hoe kunnen we onze maatschappij zo inrichten dat de wereld leefbaar blijft voor onszelf en al het andere leven om ons heen? Aan dat vraagstuk werken Leidse wetenschappers samen vanuit allerlei disciplines, van biologie tot datawetenschap en van milieueconomie tot archeologie.

How can ecosystem services within river catchments be quantified in spatial and temporal explicit way?

What are the behaviours of plant traits throughout various points in the growing season in a radiative transfer model framework and how well can this knowledge be integrated through data assimilation to provide priors for robust local and global vegetation products and analysis?

Aim: To develop and enable application of a practical, flexible, user-friendly platform to provide the scientific community with a tool to generate land surface products and its associated uncertainties and exploit these for data-intensive science.

A critical look at the impact assessment modelling of metals in Life Cycle Impact Assessment and improvement options.

Op 11 Mei 2016 is de prestigieuze NWO Vidi beurs toegekend aan Nadia Soudzilovskaia voor haar onderzoeksvoorstel met de titel “Do mycorrhizal fungi mediate soil carbon fate?”.

Dankzij de idyllische setting met parelwitte stranden groeiden de Malediven uit tot een toeristische trekpleister. Dat zorgt voor inkomens maar is ook problematisch voor de kwetsbare natuur. Met bewoners probeerden studenten van diverse universiteiten de bodem weer vruchtbaarder te maken. Hoe deden…

MINESCAPES invites PhD students from various disciplines to apply for participation in their 2024 summer school, taking place from May 31 to June 10, 2024. The Summer School will bring together students and scholars from the humanities, social sciences, and natural sciences to study mining landscapes…

Description of 20th century changes in the Dutch flora: Description and interpretation (1999 - 2005)

Do Ethiopian wolves change their diet and foraging strategy in the landscape under different land uses? How land use affect Afro-alpine rodent Communities? How important are Afro-alpine natural resources utilisation for local livelihoods? What is the human perception of conflict in the Afro-alpine a…

Analytical tools for environmental design and management in a systems perspective. The combined use of analytical tools.

Friday 30 January 2015 were the final presentations of the last course of the Minor Sustainable Development.
