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:…

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

This thesis describes the role of pollution, specifically neonicotinoid insecticides, as an actor of the ongoing biodiversity decline.

Wetland plants are distinguished from plants of other terrestrial ecosystems by their adaptations to specific habitat stresses, including waterlogged and flooding and the subsequent abundance of phytotoxic compounds.

How can mega sand nourishments, such as the Sand Motor, be designed and managed for optimal ecosystem services provision ?

Do sustainability values play a role in motivating people to act for biodiversity in successful projects and in successful leadership action? And how could these values be incorporated in current economic valuation methods?

If X is a locally compact Hausdorff space, then a representation of the complex C* algebra C_0(X) on a Hilbert space $H$ is given by a spectral measure that takes its values in the orthogonal projections on $H$.

Hogere temperaturen leiden wereldwijd tot veranderingen in de vegetatie en de bodem van berggebieden. Een internationaal onderzoeksteam met de Leidse ecoloog Ellen Cieraad publiceerde op 25 januari in Nature over de verstoring van het ecosysteem.

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…

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.

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.

In dit onderzoek wordt hersenontwikkeling voor het eerst direct gelinkt aan sekseverschillen en schoolprestatie. De resultaten ontkrachten de mythe dat jongens achterlopen in hersenontwikkeling.

Het terugdringen van agressie is in de afgelopen jaren in toenemende mate een maatschappelijke prioriteit geworden. Agressie in de vroege kindertijd vergroot de kans op latere agressieproblemen en antisociaal gedrag.
