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. ๐๐๐งช

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

Graphical abstract showing two plots illustrating distance to centroid (degree of dispersion), with the left plot showing values for Ecklonia radiata (picture of Ecklonia below, with symbol showing microbes) and right plot showing values for Sargassum (picture of Sargassum below, with symbol showing microbes). The Ecklonia plot shows greater dispersion with warming, while the sargassum plot shows no effect of treatment.

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/...

This work follows on from Annemie Rose's Masters project, where she found inner harbour kelp had higher lead and lower nitrogen concentrations, while outer harbour kelp had thicker stipes and longer and narrower laminae with spines. Read here:

Fieldwork highlight! PhD student Annemie Rose is investigating whether kelps in the inner harbour are more adapted to urbanisation ๐ฑ๐ Yesterday we collected kelp from inner and outer sites in Sydney Harbour, for experiments where she will test responses to copper and nutrients!
