Soil is a home for an unbelievable diversity and abundance of microbial life that is essential for supporting life on our planet.

How soil microbial composition impacts structure and composition of the aboveground plant and animal communities?

We will study how inoculation of former arable land with soil (including the microbiome, soil fauna and seeds/rhizomes of ground flora) from old forests along with planting targeted tree species mixtures will improve productivity and more rapidly restore forest-adapted communities and ulttimately result…

In this thesis, the role of plant-mediated soil legacy effects in shaping aboveground plant-insect interactions was investigated.

Soil biodiversity is of great importance for the maintenance of multifunctionality in terrestrial ecosystems.

This project tries to explain the persistence of this cultural repertoire by zooming in on (1) interaction between idioms (cultural repertoires) available to scholars at certain points in time, (2) mechanisms that help transmit repertoires across time and place, and (3) rhetorical purposes for which…

The soil ecosystem consists of the largest reservoir of biodiversity on Earth.

The main research question of this thesis was: Can nitrogen cycling on dairy farms on peat soil in the Dutch Green Heart area be improved by adapting management to the nitrogen supply from soil and by using other grassland species and crops without affecting milk production?

Lots of efforts are being made to promote open science practices in scholarly publishing. However, information on the openness of scholarly journals is highly fragmented. There are various data sources that provide information on specific aspects of openness, but there is hardly any integration of these…

Plants and soils from natural ecosystems harbor great diversity of soil microorganisms, which could potentially contribute to the sustainability of horticulture. The knowledge about using wild plant species and soil from natural ecosystem to improve the crop health will advance the application of ecological…

We examine how soil-derived legacy effects of plants structure natural ecosystems, determine aboveground plant insect interactions, and how we can use soil legacy effects to restore degraded ecosystems.

Below are some of the scholarly works published within the context of the Institutions for Conflict Resolution programme.

In this thesis, I focused on studying the above- and belowground interactions of J. vulgaris from a plant-soil feedback (hereafter, PSF) perspective. I investigated the temporal variation of negative PSF and examined the effects of root-associated bacteria on plant performance and aboveground herbiv…

Why did 'character', 'habit', and 'virtue' serve as key terms in late 19th and early 20th-century scholarly correspondences, biographies, and obituaries? Why did scholars around 1900 display so much interest in the working habits and character traits of what they called the 'scholarly self'?

Archaeobotanic research by prof. dr. C. Bakels and students on agriculture.

If idioms employed in codes of conduct could be as idiosyncratic as examples suggest, then to what extent did early modern language of vice, too, persist in this genre?

What evaluative languages (errors, mistakes, vices, etc.) did book reviewers employ? To what extent and on what occasions did they invoke early modern vices? And to what extent did this differ across fields or change over the course of the century?

In this PhD study, I aim to deepen our understanding of the influence of major mycorrhizal types, namely arbuscular mycorrhizae (AM) and ectomycorrhizae (EM), on the global soil carbon cycle and their potential distribution changes under future environmental shifts.

How did British scholars and scientists in the period of discipline formation envision, experience and resist scholarly temptations?

The use of N fertilizers has increased worldwide in the past century. While this increased input of N has increased food productivity, it has also contributed to decreases in biodiversity, soil quality and environmental health, including increases in greenhouse gas emissions.

Which compounds and microorganisms that live near and inside plant roots are beneficial? Can we use this knowledge to improve the health and growth of crop plants?

We examine how soil inoculation influences aboveground organisms (i) directly, and indirectly via (ii) its effects on plant chemistry or volatile emission, or via (iii) mediating the effects of belowground pathogens on aboveground organisms via the shared plant.

This volume examines how the history of the humanities might be written through the prism of scholarly personae, understood as time- and place-specific models of being a scholar.

Vinasse is a major by-product generated by the sugarcane biofuel industry. It is a source of microbes, nutrients and organic matter and often it is recycled as fertilizer.

Why does the history of dogmatism deserve our attention? This open access book analyses uses of the term, following dogmatism from Victorian Britain to Cold War America, examining why it came to be regarded as a vice, and how understandings of its meaning have evolved.

The objective of this project is to fundamentally improve our understanding of the ways in which science progresses. Empirical studies have used bibliographic metadata to provide relevant insights, but these studies have failed to tell us how science progresses. Supported by computational advances and…

Striga hermonthica, commonly known as witchweed, infests major cereal crops in Sub-Saharan Africa causing severe yield losses and threatening the livelihood of millions of resource poor farmers.

Pieter Jakob Cosijn (1840-1899) was Leiden University’s first Professor of Germanic and AngloSaxon Philology. A recognised expert in the field of Old English grammar and textual criticism, Cosijn corresponded with various prominent philologists and experts in his field, including Julius Zupitza, Arthur…

What makes a good historian? When historians raise this question, as they have done for centuries, they often do so to highlight that certain personal attitudes or dispositions are indispensable or studying the past. Yet their vieuws on what virtues, skills or competencies historians need most differ…
