Flat (thallose) liverworts often have these "gemma cups" on their surface, which contain tiny clones of the liverwort. When a droplet of water hits the cup, the clones splash forth into the great big world and eventually grow into new liverworts

Many lichens secrete a white powdery substance called a pruina. There are lots of theories about why they do this: sun protection, light concentration, removing excess calcium and even storing water in zeolite crystals. This Fulgensia subbracteata is very pruinose, but if you spray it with water, its true colour is revealed!

There are some very mysterious cryptogams that live under rocks (hypolithic) and even inside rocks (endolithic). The hypoliths usually live under rocks like quartz that allow some light through, so they can still photosynthesise but stay moist and protected. Endolithic cyanobacteria usually live in the upper layers of sedimentary rocks like sandstone.
I was recently at an old dump site with lots of smashed glass. There wasn't much biocrust around, EXCEPT underneath the glass, where there were thriving communities of hypolithic cyanobacteria and mosses!

Greater flamingo in #algarve , Portugal. They seem to love the salt ponds flying around to find the perfect water depth for each tide. Genomics tells us that the closest relatives of flamingos are grebes which suggests that evolution can be wild and unpredictable

Innsbruck is just a bit breathtaking. Yesterday it was cold and rainy in the town, but up the mountains snow was falling. Now that the clouds have cleared we have the most amazing view of the mountains 😍 Seeing these giant jagged peaks reminds me how weird the low, rounded, ancient weathered peaks of the Australian Alps are.

Off on an adventure! This morning I'm starting my looooong journey to Innsbruck, Austria, for the International Mountain Conference. I'll be presenting results from the What's in Flower project, using some neat natural history records to investigate phenological temperature sensitivity in 52 Australian alpine plants. This is a little snippet of my poster, and I'll post more during my whopping ~40 hours of travel! Wish me luck ☺️

Gigaspermum here is a very special moss. While most mosses produce a sporing structure (sporangium) on a tall stalk, Gigaspermum grows its spores in that bulbous green bit at its centre (called a sessile capsule). It also has some of the largest spores of any moss, at 0.13 mm, which is actually visible to the naked eye. The largest known spores are found in Archidium mosses, reaching 0.32 mm. The smallest vascular plant seed is about 0.085 mm

Late November is a lovely time for buttercup watching, like these felted #Ranunculus muelleri and granite R. graniticola buttercups flowering sympatrically up near one of my field sites. Granite buttercup is easy to tell from the felted buttercup, as the centre of the flower is usually darker in colour.
.
The little body of water on the left is part of a system of tiny snowmelt pools, which provides an important late spring – early summer aqueous habitat for mountain animals like frogs, dragon flies, and other alpine invertebrates. Buttercups also thrive in these wet microhabitats, flowering at full steam in late spring before the ephemeral pools dry out.

Silver snow daisies #Celmisia costiniana are one of the dominant species of the widespread Tall Alpine Herbfield community. Even though their upright rosetted leaves don't really get longer then 15cm, their floral scape can reach 40cm high, making them one of the 'taller' herbs of the alpine zone. Flowering enmass is kinda their thing too, with huge colonies exploding into a sea of white flowers late December to mid January.

In the Australian alpine, flies are really important pollinators. Yes, even those big, bitey march flies!
.
Cue shameless Croc Dundee quote: that's not a march fly, THIS is a snipe fly! I've only ever seen one of these ginormous orange and black dudes, and it was feeding on silver snow daisies #Celmisia costiniana on the Ramshead Range back in January. This is #Pelecorhynchus flavipennis, aka, the giant ti-tree fly, which I was totally stumped about until I plugged it into iNaturalist for an ID. Pelecorhynchidae are collectively known as snipe flies.
.
There's very little info out there on this beautiful, large bodied fly, but a helpful observation on projectnoah by one M. Ridgeway notes: "I have not seen this species before or since. About 34mm from the ends of folded wings to the antennae. Apparently associated with Leptospermum 'swamps where the larvae feed on roots and the adults feed on flowers. A very small family with other members only in Australasia and Chile. Quite rare and bound to become rarer as we continue to drain our little swamp lands." At lower elevations, Leptospermum swamps are a feature of the montane forests, so this little (big) fellow might have been blown up the mountain. There you go, never know what you'll see in Kosciuszko NP!
.
If you do happen to see one of these rare flies, please snap a photo and upload to iNaturalist!

In the Scandinavian tundra, there are some plants that can survive on the harsh exposed mountaintops underneath a protective (or possibly competitive) canopy of lichens. This alpine azalea is often found underneath Flavocetraria and Alectoria

When you're a wolf spider but also proud of your burrow. Many burrows of the large alpine wolf spiders are fringed by tiny prostrate flowering plants, with #Pimelea alpina, #Pentachondra pumila and #Stackhousia pulvinaris looking particularly like carefully tended flower gardens when in bloom. This particular spider has burrowed under a carpet of alpine pimelea.

Well, the hills are certainly white right now, and not with tall billy buttons #Craspedia leucantha! For anyone lucky enough to be putting in some sweet, sweet powdery turns today, do a few extra for me as I sit here in front of my laptop.
.
This winter so far has been warm and dry with irregular snowfall. For the Australian Alps, a key abiotic trait of winter climate change is decreased light and regular snowfalls, with higher and more intense precipitation (when cold, this usually means snow) occuring over fewer days. So longer periods of no snow fall followed by big snow events, such as the blizzard we're currently seeing. For those interested in long term (1958-2012) synoptic circulation and precipitation trends in the Snowy Mountains, check out the 2016 paper by Theobald, McGowan & Speirs ❄️❄️❄️
.
Botanical note: C. leucantha is endemic to the alpine zone of Kosciuszko National Park and only inhabits wet seepage areas usually within close proximity to late-laying snowpatches. While not explicitly a snowpatch species (it usually occurs outside of the community), it is dependent on summer irrigation from the melting snow.

Much like these wee Aussie alpine plants from Sophie's excellent honours project in the @unswscience glasshouse, I've been ex-situ from the mountains for the past couple of months. It's been a busy time of writing and frowning at my computer, so it was lovely to visit these experimental alpine babies, featuring all sorts of wonderful tiny plants like Neopaxia, Epilobium, Poa, Carex, Ranunculus, Geranium, Brachyscome, and Argyrotegium. Needless to say, I'm very much looking forward to the first phenology walk of spring, which is just a few weeks away (where was winter this year?).
