Citipati - ´Lord of the funeral pyre´ Kinda enchanted by this little oviraptorid and its namesake. Just had fun with it, not really going for accuracy. do like how it came out tho Might make it an artprint
Bufo, Dreadmere frogman miniature from Reaper Miniatures painted in January 2023 for a painting competition at my FLGS.
I made the bamboo from toothpicks and greenstuff, and I'm pretty proud of how it turned out. I based Bufo's colour scheme on the Eastern Japanese Common Toad (Bufo formosus).
My wild west themed Necromunda outcast gang: The Gilded Lily gang.
Heavily kitbashed from the Necromunda hive scum kit, some Malifaux bandidos, Serberey's raiders bits and random other bits from my bits box. Plus a couple gretchin and Malifaux guild hounds.
I finished these guys a little over a year ago, and still haven't had a chance to use them in a game of Necromunda, but they'll serve as the basis for my upcoming Five Parsecs From Home crew.
Shellback Crabs: these crabs create their own shields out of clamshells; their semi-membranous bodies can be pressed into the contours of the shell, producing a suction mechanism that holds the shell in place
The members of this genus (Hypoconcha) have a series of unique adaptations that facilitate this kind of camouflage behavior. Many of the Dromiidae crabs (e.g. hermit crabs, sponge crabs, shellback crabs, etc.) are equipped with a specialized pair of legs that enables the crab to hold a shell, sea sponge, and/or ascidian against their body, but shellback crabs also have a flexible, semi-membranous body that can be tucked more firmly into the contours of a bivalve shell, producing a suction mechanism that keeps the shell firmly locked in place.
The body of the shellback crab is also covered in a very fine layer of hair-like structures called setae, and when the crab presses itself against the shell, these membranous "hairs" can take on an almost translucent appearance, particularly around the margins of the crab's body.
I recently posted some photos/info about some of the crabs in the genus Lamarckdromia (which belongs to the same family) and as I was doing the background research for that post, I was just kind of mesmerized by all of these weirdly adorable crabs that seem to exist within the Dromiidae family tree. Each genus has its own unique adaptations that allow the crabs to use specific materials for camouflage -- some of them use living sponges, clamshells, ascidians, etc.
And I could not stop laughing at the little faces on these crabs. They've all got the same bemused/indignant expression...as if some random asshole has just walked up to them, shoved them over, and announced to the entire ocean that there's a crab hiding beneath that disguise; as if that actually happens to them quite a lot, and they're getting really sick of it.

Again, I don't normally feature crustaceans on my blog...but I really couldn't resist this one.

One of my favourite things in life is learning about a strange and marvellous lineage of which I was previously unaware. Evolution has produced such wonders over the past 635 million years.

omg ok so i was trying to look up how to sex a centipede and one of the first results was an obviously ai-generated article with these absolutely incredible images of “centipedes” lmao. they are so hilariously bad i just had to share
This shit is why I hate looking for art references now, 50% is ai generated dogshit being spammed by adobe and other sites. I just want coherent images for fucks sake, corporate techbro sludge muddying the waters for everyone not just artists.
In the early days of the internet, we thought we had created an easily accessible repository for all human knowledge.
We promptly started filling it with fake bullshit.
Now we've invented technology that can automatically generate infinite bullshit at scale.
I wonder how long it will take for the useless bullshit to completely eclipse the useful information...
Melospiza melodia (Song Sparrow), Zonotrichia atricapilla (Golden-crowned Sparrow) and Setophaga petechia (Yellow Warbler)
Some of the illustration assets I made for the DeZwaan et al. 2022 infographic. Read the open access paper here: https://doi.org/10.1093/ornithology/ukac027
Weather affects rates of mass gain in migratory birds during stopover
During migration, birds use stopover sites to replenish their fat reserves, which serve as energy stores. Weather affects food availability and foraging conditions, which in turn affects the rate at which they can refuel.
sing 10 years of data collected from Iona Island Bird Observatory, we found that birds gain mass more quickly with increasing temperatures, but they gain mass more slowly with increasing precipitation. These effects vary between bird species and between seasons: weather effects are stronger in spring than fall and in insectivorous warblers compared to more generalist sparrows.
Our results suggest that with changes in weather due to climate change, insectivores may be more sensitive than birds with more generalist diets like sparrows.
Iona Island is an important stopover site for migratory songbirds
Every Spring and Fall thousands of songbirds pass through Iona Beach Regional Park on their way to or from their northern breeding grounds.
Data from 10 years (2010-2019) of migration monitoring at Iona Island Bird Observatory (IIBO) shows that birds who stay longer at Iona are able to gain more fuel for the next leg of their journey.
Our results show that Iona Island provides important stopover habitat for migratory songbirds. Continued monitoring efforts at IIBO will help us understand how anthropogenic changes to Iona Island affect migratory birds.
The data from IIBO show that long-distance migrants tend to accumulate fat faster at Iona than short-distance migrants.
Birds also gain fat faster in the spring than the fall. Spring migrants are under pressure to arrive at their breeding grounds early and secure better territory
I made this infographic summarizing the results of DeZwaan et al. 2022. The paper was the result of analyzing 10 years worth of migration monitoring data collected at the Iona Island Bird Observatory in Richmond, BC. Thanks to Devin for leading this paper, and including me both as a coauthor and to Andrew for hiring me to make the infographic. https://academic.oup.com/auk/article/139/4/ukac027/6609548

Brian Hampton’s 1974 cover to A Wizard of Earthsea, by Ursula K. Le Guin
"After Ruth's unique wraparound jacket for the first edition of A Wizard of Earthsea - with its splendidly stylized, copper-brown portrait face - cover art for the books mostly went out of my control. The results could be ghastly - the droopy, lily white wizard of the first Puffin UK paperback; the silly man with sparks shooting out of his fingers that replaced him. Some covers were quite pretty in themselves, but delicate medieval persons on twee islands with castles with pointy towers had nothing to do with my earthy, salty Earthsea. And as for copper or brown or black skin, forget it! Earthsea was bathed in bleach."
- Ursula K. Le Guin, in the introduction to The Books of Earthsea: The Complete Illustrated Edition, 2016.
Hello Tumblr. I've missed you.

The Eastern Grey Squirrel (Sciurus carolinensis) I prepared late last year has finally made it’s way through the freezer. This was my first, and so far only, full mammal prep. Aside from the floppy ears, I’m very happy with how he turned out! As soon as he’s reunited with his skeleton, I’ll be able to accesion him, which means he will be given a unique number and be officially added to the collection.

Araripe Manakin (Antilophia bokermanni)
From my series “Beauty on the Brink,” which I’ve slowly been adding to for the past year and a bit. Eventually I plan on giving this treatment to all the drawings in this series and publishing them as some sort of zine. I’m very happy with how this turned out.
Araripe Manakin - Antilophia bokermanni
This songbird is endemic to the Chapado de Araripe plateau in northeastern Brazil, and has only been known to science since 1998. The males are white with black wing and tail feathers and a red crest, similar to the Helmeted Manakin, while the females are olive green. The population size has been estimated as anywhere from 150 to 700 individuals, and is continuing to decline. Due to their incredibly limited range, this species is very vulnerable to habitat loss caused by agriculture and development. The construction of several tourism and recreational facilities, including a water park in 2000 at the site where the species was discovered, have led to deforestation of the Araripe Manakin’s habitat and resulted in severe declines in their population size.
