🚨 𝗡𝗲𝘄 𝗽𝗮𝗽𝗲𝗿 𝗮𝗹𝗲𝗿𝘁! PhD candidate Annemie Rose Janssen exposed kelp populations to copper contamination to see whether kelp from the inner harbour would respond differently to outer harbour kelp. Results indicate local adaptation to contamination in the inner harbour! 🧪🌊🌐

New paper from PhD student Annemie Rose Jannsen, who found distinct #kelp genotypes in the inner and outer parts of #SydneyHarbour. Genotype-environment analyses suggest adaptation to local conditions.

Super cool results, great work Annemie Rose & coauthors!!

PhD student Natalie Coy spoke on Radio National this morning about the Seeds of the Sea citizen science project. This project asks citizen scientists to report sightings of Posidonia seagrass flowers in NSW, to inform future restoration of this endangered species. 🌊🌐🧪

A new citizen science project, Seeds of the Sea, run by one of our PhD students Natalie Coy has launched, helping to map seagrass flowering of #Posidonia in south-eastern Australia.

Check out the website and map of sightings here: www.seedsofthesea.org

Seaweed-associated microbial communities show limited responses to light pollution and warming 🌱💡

New paper assessing the independent and combined effects of #lightpollution and #oceanwarming on microbial communities associated with two habitat-forming #seaweed species 🧪🌐🌊

Light pollution caused by excessive Artificial Light at Night (ALAN) has harmful effects on wildlife. This petition calls for legislation to limit light pollution, to reduce impacts on wildlife and people. www.aph.gov.au/e-petitions/...

Another recent paper from our lab on the impact of #bushfires on sediment quality in #estuaries, led by Thayanne Lima Barros, with coauthors Mariana Mayer-Pinto, Katherine Dafforn, Stuart Simpson, Mark Farrell, Sally Bracewell and Emma Johnston.

Fieldwork highlight! PhD student Annemie Rose is investigating whether kelps in the inner harbour are more adapted to urbanisation 🌱🌆 Yesterday we collected kelp from inner and outer sites in Sydney Harbour, for experiments where she will test responses to copper and nutrients!

Hi everyone! We are the SEACS lab at UNSW, investigating Solutions for Estuarine And Coastal Stressors. Headed by Dr. Mariana Mayer Pinto, we study a diverse range of human impacts, including artificial structures, light pollution and climate change in coastal ecosystems 😊🌱✹🐚💡
