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.

Donderdag 2 Februari 2017 heeft Prof. dr. Janne Bengtsson van de 'Swedish University of Agricultural Sciences' in Uppsala een lezing gegeven met de titel:

What are interactive effects of human pressures on aquatic communities?

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

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

Met ingang van 1 mei 2018 is Nicole de Voogd benoemd tot Bijzonder hoogleraar Global Change and Marine Ecosystems bij het Centrum voor Milieuwetenschappen Leiden (CML). Zij is momenteel senior onderzoeker bij Naturalis Biodiversity Center op het gebied van tropische mariene ecosystemen.

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…

Freshwater and brackish water ecosystems are arguably the most vulnerable ecosystems on earth, due to concentrated human developments in and around them. The Pontocaspian (PC) region located at the border of Europe and Asia contains a variety of brackish water ecosystems and unique inhabitants, known…

In this thesis three different topics in number theory are studied.

1. To what extent do metallic NPs added to soil extractions change the activity, abundance, or community composition of microbes? 2. How do the effects of metallic NPs on soil microbes differ from the effects of the ions shedding from corresponding NPs?

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

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…

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

The research described in this thesis combines the latest insights in lysosomal function with lysosome centred cell signalling.

Freshwater is an important resource, but at a great risk of species decline due to habitat loss, pollution and over-exploitation, and invasive alien species.

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

Barrier function is the natural role of the skin. The lipid matrix present in the outermost layer of the skin, the stratum corneum is important for this function.

One of the effects of climate change is the phenomenon of desertification, a process that occurs in semi-arid and arid areas and causes land degradation as well as vegetation loss. Due to the lack of resources, vegetation self-organizes to sustain itself by forming large-scale spatial patterns.

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.

A common method to solve expensive function evaluation problem is using Bayesian Global Optimization, instead of Evolutionary Algorithms.

Hoe kan de methode om de gecombineerde effecten van metaal-gebaseerde chemische stoffetn te bepalen worden verbeterd?

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

This thesis consists of two main parts. The first part (Chapters 2 and 3) deals with a class of Markov process called Quasi-Skipfree (QSF) processes.

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…
