With good protective measures this part of the sea can be restored again. This illustrations was made using mixed media, with the background being made in watercolor, the animals drawn in pencils and digitally colored in Adobe Photoshop. All elements were joined together into one final image using Adobe Photoshop and Illustrator. https://images.squarespace-cdn.com/content/v1/6a15bd5879b89109e95bcad0/5cda7e3e-47c6-45f4-95b9-3207d9fee4ea/Habitats+Layout.png Scientific Illustration - Master Thesis: The subtidal Dutch Wadden Sea The subtidal Wadden Sea can be organized in six different types of habitats. In this illustration I give an overview of the six habitats that exist (even if not currently, like the Eelgrass habitat). Each habitat shows which specific species are attracted to that particular environment and show that with a combination of all six habitat types, an increase in biodiversity will be stimulated. This illustration is made in a similar fashion to the 'rich Wadden Sea' illustration, where different elements were created using mixed media and joined together using Photoshop. https://images.squarespace-cdn.com/content/v1/6a15bd5879b89109e95bcad0/4a60062e-97fe-40ec-ad96-28d3e37f6e3a/mozaiek_final_eng_V4.png Scientific Illustration - Master Thesis: The subtidal Dutch Wadden Sea I also explored different styles in which to convey scientific information. Since the research project for which these illustrations were designed was called 'the Wadden mosaic', I wanted to incorporate a mosaic of sorts into one of the illustrations. In this piece, the difference and impact of having a low variety in habitats in the Wadden Sea vs a high variety in habitats is clearly shown. With all six habitats incorporated, the picture becomes more colorful and the biodiversity increases. https://images.squarespace-cdn.com/content/v1/6a15bd5879b89109e95bcad0/7b17cbb9-028a-4da4-a162-7e232c8986ab/gradatieBescherming_final_eng_V5.png Scientific Illustration - Master Thesis: The subtidal Dutch Wadden Sea With effective protection of the Dutch Wadden Sea, more than one thing happens: besides an increase in biodiversity, a more complex and efficient food web starts to develop. This can be seen by the increase in different species, the more effectively protected this area is, and the decrease in water turbidity, with more sun-rays reaching the Eelgrass. https://images.squarespace-cdn.com/content/v1/6a15bd5879b89109e95bcad0/fb64f2ea-59f1-46b9-bded-7f0557b07b35/perenboom+rif+layout5.jpg Scientific Illustration - Master Thesis: The subtidal Dutch Wadden Sea One of the projects in 'the Wadden mosaic' was the research of adding man-made reefs to the sea. Old discarded pear trees were transformed into constructions that give a hard substrate to shellfish, sea lettuce and other sessile species. This is another way to increase biodiversity. https://images.squarespace-cdn.com/content/v1/6a15bd5879b89109e95bcad0/dda47255-bc57-42ea-982b-c5efeae02a69/Species+poster.png Scientific Illustration - Master Thesis: The subtidal Dutch Wadden Sea Poster of some typical species that appear in the subtidal Dutch Wadden Sea and are mentioned in the thesis. This was also used as the cover for the thesis. https://www.annejasker.nl/portfolio/project-one-f5w4d-z9nem-s3jda-eyssk-a6prr-t4kk7-n7mdr monthly 0.5 2026-06-04 https://images.squarespace-cdn.com/content/v1/6a15bd5879b89109e95bcad0/5eb3cae7-32aa-428c-9708-916f6d67a851/A3b+V4_A_Jasker.png Scientific Illustration - Medical illustrations During my Master's degree I got the opportunity to dissect and study a human hand. I found this process very interesting and made this oil painting of the dorsal side of the hand, showing the tendons, muscles and fat. I created this mock-up of a book cover, discussing the idea that although scientific illustrations need to be accurate and functional, they can also portray beauty and be appealing to the eye. https://images.squarespace-cdn.com/content/v1/6a15bd5879b89109e95bcad0/03e13d50-6e60-43c8-8155-dd2159f3447d/A4b_A_JaskerFinal1.png Scientific Illustration - Medical illustrations Illustration depicting the human skeletal system and the muscles of the upper and lower leg, from the lateral/frontal side. https://images.squarespace-cdn.com/content/v1/6a15bd5879b89109e95bcad0/81714cea-7cb0-4c75-84c0-98239fc6833a/skellyfixed-01.png Scientific Illustration - Medical illustrations Anatomy poster of the human torso. https://images.squarespace-cdn.com/content/v1/6a15bd5879b89109e95bcad0/6360222b-a1f0-448b-9d28-a16cf4f830e4/femurcoloured.png Scientific Illustration - Medical illustrations Illustration of a head of a human left femur. https://images.squarespace-cdn.com/content/v1/6a15bd5879b89109e95bcad0/9bcfd099-be1c-4e32-9dc1-da8ff5069ce1/C2_A_Jasker_PVCRAT.png Scientific Illustration - Medical illustrations Staged microsurgery on a rat.
