It is well-known that humans have significantly transformed ecosystems since their adoption of agriculture. However, in a deeper past, prehistoric hunter-gatherers may already have altered and modified their niche in ways that had major impacts on ecosystems.

Environmental humility is integral to addressing the climate crisis, but humility can also lead to political domination. How can humans relate to nature more humbly without risking domination?

The multiple connections between emblematics and Natural History in the broader perspective of their underlying artistic, literary, political and religious ideologies.

The Historia Naturalis Brasiliae Reconsidered

This dissertation is a study of the view of the Neoplatonist Proclus (Athens, 411-485) on to what extent and how the changing and unreliable world of sense perception can itself be an object of scientific knowledge.

- Which metabolites could be components of NADES? - How can we prove the presence of NADES in nature? - What are the roles of NADES in nature? - How to apply NADES in life sciences?

The Netherlands is not particularly rich in ‘wild nature’. Comparatively, what we have is a lot of intensively used agricultural land. This means that from nature’s perspective there much to be gained by combining the ‘nature’ and ‘agriculture’ functions. Not an easy task in such a densely populated…

This dissertation explores Aristotle’s use of teleology as a principle of explanation, especially as it is used in the natural treatises.

This project launches a research program into the theoretical status and the terminological basis of evidentiality systems.

A neural network mimics how our brain works. Evolutionary algorithms use the principle of natural selection to solve complex problems. This kind of 'natural computing' is being used to improve the diagnosis of Parkinson's disease or the production of steel.

The Laboratory for Human Osteoarchaeoloy examines human remains and their burial context to address questions about the human past.

This project, under the supervision of Prof. Dr. Hans van der Plicht, comprises several studies aimed at the use of isotopes occurring naturally in organic material as tracers for both the climate change and its cultural impact at about 6200 BC. The research will be carried out by the co-applicant at…

We depend on nature for so many things: from clean water, wood and food to carbon absorption, water purification and coastal protection, as well as for relaxation, inspiration and identity. Nevertheless, our modern world putting increasing pressure on these ecosystem services. Leiden researchers investigate…

Natural history collections provide invaluable sources for researchers with different disciplinary backgrounds, aspiring to study the geographical distribution of flora and fauna across the globe as well as other evolutionary processes.

LUGO's Autumn Event 'Requiem for Nature' took place late November and was a great success!

This project investigates the transposition of natural historical material, knowledge and vision, between different media (collection, scientific drawing, academic texts, the visual arts and/or literature) – a transmission that happens in the borderline between the traditional, emblematic worldview…
