Development of an aggregated impact indicator to measure decoupling.

Plant diversity is essential for us and our planet as it sustains the stability of our ecosystems, provides vital materials and food to us and supports many ecosystem services.

The recently introduced nature-originated deep eutectic solvents, so-called natural deep eutectic solvents (NADES) are considered as truly green solvents, which composed of natural ingredients found abundantly in organisms.

As a contribution to the changing legislation and evolving societal attitudes concerning environmental issues, this project aims to enhance and manipulate the plants’ own natural defense mechanisms against western flower thrips (WFT).

Het onderzoeksgebied Natural Computing is uitgegroeid tot een onderzoeksgebied met een spannende interactie tussen informatica en natuurwetenschappen en een belangrijke katalysator voor deze twee-weg interactie. Dit driedelige handboek van meer dan 2000 pagina's is een belangrijk verslag van deze belangrijke…

Large carnivores and humans, along with their livestock, have co-existed for thousands of years. However, human population growth and an increase in economic activities are modifying the landscape for large carnivores and their prey.

ENVIRHUS (Environmental and Rural History of Urbanized Societies) organiseert op 17 februari 2023 (14u-17u) de workshop ‘The Natural World‘.

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…

Natural resources often stretch across borders that separate modern nation states. This can create conflict and limit opportunities for regulated consumption of their goods and services, but also provide opportunities for joint multinational efforts that exceed single country capabilities.

Prof.dr. Geert de Snoo is per 1 maart bij de Faculteit der Wiskunde en Natuurwetenschappen benoemd tot hoogleraar Conservation Biology. De Snoo blijft hoofd van de gelijknamige afdeling van het Institute of Environmental Sciences (CML).

Multi-criteria optimalisatie is een effectieve techniek voor het vinden van optimale oplossingen die een afweging bieden tussen verschillende, tegenstrijdige criteria. Het heeft zijn toepassing gevonden in de wereld om ons heen omdat bij het oplossen van praktische, re¨ele wereld problemen men gewoonlijk…

Hortus botanicus Leiden is de eerste Nederlandse tuin die een accreditatie heeft ontvangen van Botanic Gardens International (BGCI).

Given the accelerating appearance of antimicrobial resistance, there is an urgent need for more fundamental research into novel antibiotic strategies. The work in this thesis helps to address this global problem by developing new antibiotic compounds, inspired by the antibacterial mechanisms of the…

What is movements and corridors of the Bornean pygmy elephant in Sebuku forest? What is the nature of human-elephant conflict in Nunukan District in time and space? What are the diets of the Bornean elephants related to crop raiding?

The ongoing increase in antimicrobial resistance combined with the low discovery of novel antibiotics is a serious threat to our health care.

Actinobacteria are well known for the production of bioactive natural products, many of which have applications in the fields of human, animal and plant health. Subject of this thesis are the anthracyclines, glycosylated aromatic polyketides with potent anticancer activity.
