How presence, abundance and enzymatic activities of AM and EM fungi differently affect soil carbon sequestration processes?

The external tissues of plants and animals are colonized by microbial communities termed microbiota. When organisms are exposed to environmental pollutants, these substances will therefore encounter microbiota at the exposure interface.

The effects of anthropogenic noise on interactions between predators and their prey are still little understood.

This article examines the position of victims and those affected within communication theory. Current research has broadly been skewed toward reputation management and protecting brand value as primary goals of crisis communication efforts. The authors offer recommendations for crisis communication…

How do cognitive, motivational, and affective processes interact to select actions?

How and under what conditions Dutch primary school principals' managerial networking activities affect the performance of their school

Humans and songbirds learn their vocalizations early in life by exposure to the vocalizations of adult conspecifics. Often, better learning outcomes are achieved with live, social, tutors than with audio-only exposure to vocalizations.

The research master's specialisation Developmental Psychology consists of five main parts: the general courses, the specialisation-specific courses, the elective courses, a research internship and a thesis.

In what ways do matters of cybersecurity affect the relationship between governments and citizens, have a bearing on (fundamental) rights and civil liberties, and alter the role and responsibilities of governments?

Political scientists Marijn Nagtzaam (Leiden University) and Patrick van Erkel (University of Antwerp) investigate how electoral rules affect intra party preference voting. Focusing on the effect of two specific rules—the option to cast a list vote and on a single versus multiple preference vote—and…

Explaining cutback management strategies in public sector organisations: change leadership in times of crisis. How does the publicness of organisations affect the choice and implementation of cutback management strategies?

How interest groups, differences in policy issues and institutional differences between countries affect whether public opinion is translated into policy?

What are interactive effects of human pressures on aquatic communities?

Due to technological change, jobs and professions are constantly changing. For instance, it has long been known that some jobs are becoming redundant due to automation. Digitalisation and the rise of artificial intelligence are more recent developments that affect the labour market.

Many countries and regions face a wide variety of challenges resulting from migration and mobility. Solutions that have been formulated range from policies and regulations for immigration, to education and stimulating social participation, to restructuring the welfare state. These challenges and policies…

The Institute of Biology Leiden (IBL) is an internationally oriented institute for research and education in biology.

How can we improve quality of life and study success in young, high-functioning adults with autism?

An analysis of people’s access to justice and the working of (legal) institutions in post-conflict, democratic Libya

Lysosomal storage disorders (LSDs) are a group of orphan diseases characterized by lysosomal dysfunction or impaired lysosomal catabolism and affect collectively about 1 in 5000 live births.

In which way and to which extent is integration articulated in concept maps and which factors affect the resulting concept maps? By which factors is the perceived usefulness of such concept maps affected?

Atopic dermatitis (AD) is a common inflammatory skin disorder characterised by various epidermal alterations. Filaggrin (FLG) mutations are a major predisposing factor for AD and much research has been focused on the FLG protein.

This research programme aims to increase the scientific understanding of how current and emerging anthropogenic threats affect biodiversity and ecosystem services to facilitate strategic management of natural resources. To this end, we address urgent challenges in relation to the mechanisms involved…

Computers are capable of making incredibly accurate predictions on the basis of machine learning. In other words, these computers can learn without intervention once they have been pre-programmed by humans. At LIACS, we explore and push the borders of what a revolutionary new generation of algorithms…
