One of first species I worked on during my PhD, Pterostylis longifolia with Mycomya sp. fungus gnat pollinator.

The end of the PhD journey

December 15, 2022

It was over five and a half years ago when I first sat down at my PhD desk to begin my journey to uncover the secrets of Pterostylis pollination. A lot has changed since then - we moved buildings at uni, I spent years in the field chasing gnats and in the lab working out chemistry, I published two papers on my research, I moved to Arnhem Land and moved back again, I started working in the public service and I submitted my PhD thesis.

Today, at least symbolically, I capped off that journey as I graduated from my PhD at the ANU.

It's pollinator week!

November 13, 2017

This week, from the 12th to the 19th of November, is Australian Pollinator Week. It was created to raise awareness of the importance of pollinators and of the recent declines in insect abundance. Say g'day to an insect, plant a flowering shrub, and don't use pesticides, and the indispensable insects may just survive.

A new Banksia: the scarlet Banksia

September 12, 2017

It is entirely possible that each time I go to WA I will come back with a new favourite Banksia. This August, Ali and I discovered the gaudy, eye-watering colours of Banksia coccinea, the aptly named scarlet Banksia.

I was recently asked to provide images of Red-kneed Dotterels for a sign at Jerrabomberra, and I had to go off digging in my old hard drives from way back in 2011. I’d forgotten that I’d spent a magical afternoon at Calperum Station with Red-kneed Dotterels coming almost within touching distance in beautiful sunset light. At the time I was out with @hoops.daniel helping him catch dragons near Renmark in South Australia for his PhD. . . #redkneeddotterel #southaustralia #australianbirds #ausgeo #canonaustralia #plover #birdsofinstagram #birdphotography #bird_brilliance

The lowly greenhood is quite an incredible orchid. It grows in central northern Victoria and flowers in November-December at a time when most other orchids in the area have died off for the season. It grows on soil which is baked hard by the hot sun and seems an inhospitable place for a delicate little orchid to be growing. Plus, it is rare and just looks damn cool! . . #australiannativeorchids #australiannativeplants #pterostylis #pterostylisdespectans #summer #orchids #ausgeo #canonaus #macro_secrets #zeiss100mmf2

A little bit tongue-in-cheek 😛 I don’t think I’ll ever get tired of how weird these plumed greenhoods are. The densely hairy labellum is probably involved in pollinator attraction somehow but exactly how is unclear. There is some suggestion dagger flies are involved in pollination (including a great set of photos by Rudie Kuiter) but evidence is still scarce. . . #australiannativeorchids #pterostylis #greenhood #ausgeo #orchid #australiannativeplants #macro_secrets #zeiss100mmf2
