Seagrass research illustrations: Seagrass propagates via underground rhizomes (roots). For evolutionary biologists, it is crucial to know how exactly the genetic information is passed on to the new plants and what effects mutations can have on an entire population.

Short animated video on the findings of my PhD thesis



Global warming of the ocean increases tar risk of Vibrio infection in pipefish (Syngnathus typhle). In healthy condition they favor warm water, as this increases their reproductive success. However, if infected with Vibrio bacteria, pipefish show a counterintuitive behavior and actively choose cooler waters. The chance of getting infected is smaller and immune response functions better in cooler water. This illustration shows in a simple way how complex scientific relationships can be presented in an appealing and easily understandable way.



The illustration is based on the research results described in:

Landis et al. 2012: Behavioral adjustments of a pipefish to bacterial Vibrio challenge. Behavioral Ecology and Sociobiology 66:1399-1405. 

In this illustration the most common species of animals are visualised in a seagrass meadow. It also contains the information that seagrass reproduces clonally through underground roots (rhizomes).
