Symbionts have a unique mode of life that has attracted the attention of ecologists and evolutionary biologists for centuries. As a result of this attention, these disciplines have produced a mature body of literature on host-symbiont interactions. In contrast, the discipline of symbiont conservation is still in a foundational stage. Here, we aim to integrate methodologies on symbiont [...]
Sexual Selection in Bacteria?

A main mechanism of lateral gene transfer in bacteria is transformation, where cells take up free DNA from the environment which subsequently can be recombined into the genome. Bacteria are also known to actively release DNA into the environment through secretion or lysis, which could aid uptake via transformation. Various evolutionary benefits of DNA uptake and DNA release have been proposed but [...]
Rapid isolation and characterization of microsatellites in the critically endangered Mountain Bongo (Tragelaphus eurycerus isaaci)

High-throughput sequencing tools promise to revolutionize many aspects of genetics research, e.g. by allowing the identification of functional adaptive genetic variation. However, the expense and expertise required to apply these tools to basic conservation questions is a challenge for applications outside academia, resulting in a so-called “conservation genomics gap” (Shafer et al. 2015). The [...]
DNA methylation patterns in the round goby hypothalamus support an on-the-spot decision scenario for territorial behaviour
Published: 2018-12-11
Subjects: Genetics and Genomics, Genomics, Life Sciences
How early life experiences are stored on a molecular level and affect behavioural phenotypes later in life is not well understood. In fish, reproductive phenotypes are often easily discernible and frequently depend on previous life experiences. DNA methylation is an epigenetic mechanism which is both sensitive to environmental conditions and stable across cell divisions. In this study, we [...]
