sharon Wismer, PhD
I am a marine ecologist and live in Switzerland with my husband, two children and a lively bunch of pets! I’m passionate about sharing the wonders of science and nature with kids, which inspired my shift from academic research to science communication. My background in academia and research focused on tropical coral reefs, climate change, cooperation and fish behaviour on the Great Barrier Reef. As a children’s non-fiction author, my goal is to make science and emerging research fun and accessible and to inspire the next generation of young naturalists.

Research
1. Postgraduate research
My postgraduate research focused primarily on the behavioural strategies of bluestreak cleaner wrasse (Labroides dimidiatus) – one of the ocean’s most clever fishes! Cleaner wrasse live on coral reefs across the Indo-Pacific Ocean and maintain territories called ‘cleaning stations’. As their name suggests, cleaner wrasse clean and remove ectoparasites from so-called fish clients.
While the relationship is mutualistic – the cleaner fish gets food and the client gets health benefits from being cleaned – cleaner wrasse also bite by removing fish mucus and scales! This is considered cheating.

Using cleaner wrasse as a model system for cooperation, I investigated important mismatches between standard theoretical predictions regarding animal decisions during cooperative interactions and experimental data, and explored how well cleaner wrasse are able to identify and use relevant cues for decision making.

2. Postdoc research
During my postdoctoral studies, I investigated
the impacts of mass coral bleaching on
coral-associated reef fishes.
Mass bleaching events occur when the symbiotic relationship between corals and their photosynthetic algae breaks down in response to prolonged, elevated water temperatures during marine heat waves. These events are climate driven and are sadly increasing in frequency. Widespread coral mortality often follows bleaching events and represents a major disturbance event for reef organisms, especially for reef fishes that depend on corals for food or shelter.
Using replicate photo quadrats that were spatially-matched across time, we quantified the response of fishes and corals to mass bleaching before, during and after the 2016 mass bleaching event on the Great Barrier Reef.
