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…

How can we monitor and protect biological and cultural diversity in Suriname best? What can we learn from local knowledge and customs associated with biodiversity? How can we understand current species, acoustical, behavioural, and ecological diversity from an evolutionary perspective? Can we predict…

How does invasive hybridization affect threatened native species?

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.

In Leiden University's Vision on Sustainability 2030, biodiversity (biological diversity) is an important focus in its teaching and research and on its campuses.

The master’s specialisation Biodiversity and Sustainability at Leiden University provides students with a much better understanding of the biological processes which are essential for creating a sustainable society.

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?

The project aims to conserve and consolidate the entrance gate to the Roman Desert Frontier Fort Qasr Bshir.

Biodiversity is under pressure worldwide, but is essential for our health, food security and well-being. What is the influence of human actions on ecosystems? Can we provide biodiversity-inclusive solutions for our key societal challenges? These questions are central to the Biodiversity research the…

This research programme aims to increase the scientific understanding of how current and emerging anthropogenic threats affect biodiversity and ecosystem services to facilitate strategic management of natural resources. To this end, we address urgent challenges in relation to the mechanisms involved…

Evolution & Biodiversity is one of the four research themes of the Institute of Biology Leiden.

For a first time the atlas maps the soil biodiversity of the entire planet, and provide s comprehensive analysis of human-induced threats to soil organisms and soil functioning, facilitating development of new policies to protect soil and soil organisms.

As we are working very hard to make our University more green, it is of upmost importance that you join us in our battle and start increasing the local biodiversity from your own house! Every bit will help, it is beneficial for you own mental health and most importantly it is fun! We have created this…

This project aims to develop advanced data analysis methods for monitoring and increasing our understanding on biodiversity dynamics in nature reserves such as the Oostvaardersplassen.

Leiden has one of the most petrified inner-cities of The Netherlands. This is not beneficial for the biodiversity crisis and Leiden University, with a significant number of buildings within the Singels, should be more proactive on this matter. Currently, LUGO is taking steps with internal departments…

Microbial Sciences' contribution to the Evolution & Biodiversity research theme focuses on understanding how bacteria sense and respond to their environment, and how bacterial diversity and evolution is influenced by cooperative and antagonistic interactions taking place between microbes.

Plant Sciences' contribution to the Evolution & Biodiversity research theme is to understand what are the key drivers of plant biodiversity during evolution with a focus on plant life history and resilience traits and develop tools to restore and maintain plant biodiversity.

Animal Sciences’ contributions to the Evolution & Biodiversity research theme include evo-devo research, the evolution of cognitive and behavioural traits, and the evolutionary mechanisms of stress adaptation. This research involves both indoor and outdoor studies.

Freshwater biodiversity has been threatened by eutrophication due to excessive nutrients in the environment. Releasing the freshwater species from such pressures requires efforts from industry and manufacturers to avoid emissions to vulnerable and high-risk regions.

Dina Ishak Bakhoum defended her thesis on 21 January 2021

In his dissertation Michiel Hooykaas outlines the results of six empirical research projects focused at biodiversity awareness in the Netherlands, specifically people’s knowledge about animals.

This thesis focuses on the social dimensions of crane and wetland conservation in rural landscapes in Kenya, Uganda and Zimbabwe.

Evolution acts via mutations in amino acid sequences. Substitution of essential amino acids leads to a nonfunctional protein. l.

Does a high quality prairie restoration in an urban/agricultural landscape provide invertebrates necessary for a sustainable ecosystem?

A management strategy has been developed for field margins to reduce pesticide drift to non-target areas and to promote biodiversity on arable land. To this end, 3 and 6 m wide strips along the edges of winter wheat, sugar beet and potato crops have been left unsprayed with herbicides and insecticides…

The Vallesian, 11.1-9 Ma, was a special time in the Vallès-Penedes basin near Barcelona, where a biodiversity hotspot existed. Europe had a subtropical climate, with rhinos, forest giraffes, lions, hyenas, flying squirrels and primates.

What are the effects of light pollution from cities and bridges and noise pollution from passing vessels and nearby road traffic on migratory fish passage and spawning in rivers?

During his visit on 12 April 2016, Dr. Jatna Supriatna was appointed as visiting scholar at the Faculty of Science of the Universiteit Leiden. Dr. Supriatna is a biologist, and is a senior lecturer at Universitas Indonesia’s Department of Biology. His appointment was made in the context of increasing…

It came as a shock to many people: one million plant and animal species are threatened to become extinct. But this number isn’t the most relevant aspect, argue Alexander van Oudenhoven, Koos Biesmeijer and three other experts in Dutch newspaper Trouw. ‘It is more important to realise that the fate of…
