I am a marine biodiversity scientist at Museums Victoria in Melbourne Australia. I love biogeography and evolution.
New paper in Nature: global evolutionary biogeography of my favourite animals.

Spatiotemporal faunal connectivity across global seafloors
Our knowledge of biogeographic patterns and processes in the deep sea has been limited by the lack of integrated datasets that cover its vast extent. Here we analyse a new global dataset of genomic DN...

It’s out! A new faunal inventory for deep sea habitats around cold seeps off Costa Rica, including sone cool brittle-stars, see zookeys.pensoft.net/article/1343...

Here is the long lost brittle star Asteroschema monobactrum, last collected over a hundred years ago, from the SE seamounts of Chile. Merry Christmas!! #oceancensus #museumsvictoria

I have found old friends on seamounts in the SE Pacific, same species as from seamounts off New Zealand & Australia. Never ceases to amaze me how far these animals have dispersed across open oceans. #taxonomyworkshop2024-ID #chile

Woohoo, the Cocos (Keeling) Island seamount makes the front cover of DSBII. Mapped for the first time by the RV Investigator in 2022. Now I had better finish the macroecology paper …

Today’s marine biogeography thought: the first brittle stars to reach remote oceanic islands are Amphipholis squamata & Ophiactis savignyi, both polyploids! Super-dispersers!
