CurveBend project aims to study the restauration of biodiversity in livestock landscapes through collective action, practical solutions, and research on ecological knowledge co-creation.

Zijn sociale aspecten van anxiety-like gedrag bij zeer jonge zebravissen al aanwezig? Zijn deze afhankelijk van de coping style (persoonlijkheid) van het individu? Zijn deze gedragingen endocrien te moduleren, bv door oxytocine?

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.

What is the provenance of introduced populations?

In honour of 10 years of cooperation between Kenya Wildlife Service and Leiden University, a Leiden delegation visited Nairobi National Park. To cement the cooperation, a lion in the park was collared and named Karel, which in Dutch literally means ‘free man.’ It will be monitored through satellite…

What the Sex Lives of Bugs, Birds, and Beasts Tell Us About Evolution, Biodiversity, and Ourselves, Menno Schilthuizen reports from the front lines of evolutionary biology, on a quest to make sense of the origins, workings and evolution of our and other species’ reproductive selves.

1. What is the exact role of PIN proteins in PAT? 2. How is PIN polarity established, and how is it modulated by AGC kinase-mediated phosphorylation? 3. What is the role of the AGC kinase, as modulators of PAT, in translating environmental signals, such as gravity, light or mechanical stress, to plant…

How can we understand the material instability of photographic (mixed media) artworks (1960s - present) from an integrated approach of Art History, Conservation Science and Chemistry in order to preserve these works for the future?

Lions in West and Central Africa form a unique group, only distantly related to lions in East and Southern Africa. Biologists at Leiden University confirm this in an article published in Scientific Reports.

Do natural soundscapes affect migratory decisions of fishes moving up and down rivers and is this process disturbed by vessel sounds?

Around 1,300 Leideners found 2,265 species during the Expeditie Stadsnutuur urban biodiversity inventory. ‘It’s been a huge success’, says scientific coordinator Frederic Lens.

How do societies move forward with sustainable, effective and efficient management of Earth's water resources?

Are there acoustic cues for settlement stage larvae in deep-sea soundscapes around hydrothermal vents?

How can species literacy in the Netherlands be explained and improved?

At the start of the 20th century there were fewer than 2 billion people. Now at over 7 billion, Earth’s population is on target to reach 8 billion by 2027. How has this dramatic increase in human population impacted Earth’s life support systems and natural resources? How should we understand the meaning…

Human measures to protect lions have an impact on the genetic health of populations. Leiden and Kenyan scientists discovered this by analysing the DNA of 171 Kenyan lions. ‘By fencing reserves, for example, the chance of inbreeding increases.’ With the knowledge and tools from the research, management…

Female and male songbirds sing equally elaborate songs in some species, but in others, females do not sing like males or not at all. How did such pronounced differences in male and female communication evolve?

Do humans and zebra finches share cognitive mechanisms that are important for speech perception?

How has early development in R. ocellatus been modified as a result of its parasitic embryonic lifestyle?

How can we track biodiversity loss at the speed and scale needed to protect our ecosystems? The eDNA Citizen Science project combines cutting-edge environmental DNA technology with citizen science to enable residents, community groups, and local organizations to monitor aquatic and terrestrial biodiversity…

Does knowledge of environmental performance change farmer's behaviour?

A theoretical project on the insights gained by human (including infant), nonhuman animal and computational studies on artificial grammar learning; identifying the critical questions for future research by developing novel experimental and computational approaches to address these issues.

What is vegetation structure and composition in SFM primary forest, secondary logged over forest (logging FSC certified and logging non certified) in comparison to primary forest? What is avian guild diversity in SFM primary forest, secondary logged over forest (logging FSC certified and logging non…

CML Researcher Merlijn van Weerd wins Parker / Gentry Award 2015 for Conservation Biology at Field Museum Chicago in recognition of his commitment to biodiversity conservation in the Philippines

As part of the Leiden Erfgoed Deal, the Municipality of Leiden collaborates with Leiden University, Naturalis, and the Leiden Regional Heritage Office, to study the climate challenges facing the city centre and its historic green and blue networks. The goal is to contribute to a biodiverse, climate-resilient…

Hortus botanicus Leiden is the first Dutch garden to receive an accreditation from Botanic Gardens International (BGCI). The Conservation Practitioner Accreditation is a certificate that recognizes the policy, knowledge & expertise and education with regard to plant conservation at an international…

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…

How is vegetative development regulated in plants and how does this affect a plant’s life history strategy?

How did toxin genes evolve from harmless physiological genes?

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:…
