How are links between macro-invertebrate diversity and ecosystem functioning influenced by anthropogenic pressures?

What are trait-trait relationships in wetlands? To what extent the so-called leaf economics traits deviate from terrestrial ecosystems? How traits specific to wetland plant relate to plant strategies? What’s the relationship between wetland plant traits to the ecosystem functioning (e.g. productivity,…

1: What is the relative importance of alfa and beta biodiversity in polar ecosystems, and how does intraspecific variation influence this? 2: How can we use remote sensing to determine functional biodiversity (within communities) in polar ecosystems? 3: Temporal and spatial scales of functional biodiversity:…

While ecosystems have concrete benefits for human society, these benefits are typically overlooked in decision-making.

What are the global relationships between environmental conditions and abundance of distinct types of mycorrhizal fungi in soil and plant roots?

1) Assess the trends in supply and production status of these critical minerals and mineral products worldwide and Europe’s dependence including on intermediate products such as permanent magnets, RE based super alloys, batteries, polishing compounds, phosphors, catalysts etc. 2) Trace the entire value…

The four possible segments A, T, C and G that link together to form DNA molecules, and with their ordering encode genetic information, are not only different in name, but also in their physical and chemical properties.

Ethiopian wolves are endangered diurnal Afroalpine rodent hunters. I investigated the interaction between wolves, rodents and human land use in Borena Sayint National Park (BSNP), Abune Yosef and Aboi Gara in Ethiopia.

Op 7 november 2018 verdedigde Catherine Harwood haar proefschrift 'Navigating Between Principle and Pragmatism: The Roles and Functions of Atrocity-Related United Nations Commissions of Inquiry in the International Legal Order'. Het promotieonderzoek is begeleid door promotoren prof. dr. L.J. Van den…

Marine sponges are important members of reef ecosystems, as they play ecological roles that are essential for the health of the reef.

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.

What are interactive effects of human pressures on aquatic communities?

This work is dedicated to interpreting in cohomological terms the special values of zeta functions of arithmetic schemes.

Binnen de eerste subsidieronde van het NWO-onderzoeksprogramma Complexity is het project 'Critical transitions and early-warning signals in spatial ecosystems', gezamenlijk ingediend door Arjen Doelman, Jens Rademacher (CWI) en Max Rietkerk en Martin Wassen (beiden geowetenschappen, UU), gehonoreerd…

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

Een kleine geschiedenis van het leven op aarde, verteld aan de hand van eilanden. Wat kunnen wij leren van deze werelden in miniatuur?

Metal complexes and 2D materials like graphene were combined to produce structures that can function as sensors.

Sphingolipids are important membrane compounds with a variety of functions. In mammalian cells, different enzymes are involved in the metabolism of sphingolipids, but interruption of this metabolism process leads to different diseases.

It is a common technique in global optimization with expensive black-box functions to learn a surrogate-model of the response function from past evaluations and use it to decide on the location of future evaluations.

The thesis explores how interstellar chemistry evolves as a function of time and changing physical architectures during the formation of stars.

The long-held desire - to link structure directly to function and to explain molecular mechanisms based on basic chemical or physical principles - is finally coming closer, satisfying not only our scientific curiosity but also offering new solutions to the many challenges in the field of health, energy…
