In this thesis, I investigated the neurogenetic properties of Neotropical bat species. Bats represent the second largest mammalian order (Chiroptera) in the world, with Neotropical bats constituting about 13% of the total number of bat species.

In light of climate change, it is crucial to determine whether plant species can adapt to future climates to avoid extinction. Plants adapt to various conditions by altering their functional traits, such as leaf size or photosynthetic rate. Some traits appear linked and vary together between species,…

DNA carries various forms of information. Out of these forms of information the most well-known is classical genetic information.

The applications of studying the early development of insects range from agriculture to material science.

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.

Fungal food spoilage often starts with a contamination with spores. Experimental data strongly indicate the existence of subpopulations of spores with different levels of resistance to preservation methods.

The four possible segments A, T, C and G that link together to form DNA molecules, and with their ordering encode genetic information, are not only different in name, but also in their physical and chemical properties.

Despite their ecological, cultural, and economic importance, lion (Panthera leo) populations in Kenya are declining rapidly due to retaliatory killings following livestock depredation, depletion of wild prey, habitat loss driven by human activities, climate change, and disease.

This thesis describes the genetic and prokaryotic diversity of giant barrel sponges.

Leeuwen in West- en Centraal-Afrika vormen een unieke groep, die relatief weinig verwant is met leeuwen in Oost en zuidelijk Afrika. Biologen van de Universiteit Leiden bevestigen dit in een artikel gepubliceerd in Scientific Reports.

Streptomyces are multicellular, Gram-positive bacteria in the phylum of actinobacteria which produce a high amount of bioactive natural products of which the expression is tightly coordinated with the life cycle.

Animal diet studies are critical for understanding ecological processes such as trophic interactions, energy flow, and nutrient cycling. By examining what animals consume, ecologists gain insights into species specialization, predator-prey relationships, and ecosystem management.

Organisms often need to adapt more efficiently and devise new strategies for surviving difficult ecological circumstances.

Hybrid zones occur where two species meet and produce offspring (hybrids). Typically, hybrids show a considerable reduction in fitness. In this thesis two hybrid zones are treated.

Lysosomal storage disorders (LSDs) are a group of orphan diseases characterized by lysosomal dysfunction or impaired lysosomal catabolism and affect collectively about 1 in 5000 live births.

The bacterial cell wall is a nearly universal structure that offers protection and gives the cell its shape. However, environmental stressors, such as cell wall-targeting antibiotics and hyperosmotic conditions, can induce bacteria to shift to a wall-deficient state. It is unknown whether the lack of…

The study of orchid flowers, fruits, and inflorescences is crucial due to the remarkable diversity of orchid species and their unique adaptations to pollinators and seed dispersers. However, our understanding of the evolution and development of these organs within the orchid family remains limited.

Inactivating mutations in BRCA1 or BRCA2 genes predispose to several types of cancer.

The PID-directed shift in PIN polarity has been broadly accepted as one of the essential mechanisms for the regulation of auxin transport polarity.

In populations with a seed-bank, individuals can temporarily become dormant and refrain from reproduction until they can become active again. The repository of all dormant individuals in the population is called the seed-bank. Seed-banks are observed in many taxa, including plants, bacteria and other…

In this thesis, we used genetically engineered mouse models to identify genes and pathways that are involved in ILC formation and in the development of resistance to FGFR-targeted therapy.

De master Biology is een samenwerking tussen het Instituut Biologie Leiden, Naturalis en het Centrum voor Milieuwetenschappen Leiden waardoor het programma een brede en diverse scope heeft. De opleiding biedt zeven specialisaties, waarvan vier researchspecialisaties die nauw verbonden zijn met het onderzoek…

Despite substantial progress in understanding tuberculosis (TB), the eradication of the TB epidemic is still far from reach.

Glycosidases are important enzymes in the turnover of polysaccharides and glycoconjugates, and are involved in a range of human pathologies including genetic disorders such as Gaucher and Pompe disease, but also in various cancers.

The RNA guided endonuclease based on the CRISPR/Cas system of Streptococcus pyogenus is a potent new tool for genome engineering in plants.
