🐌 How much data do we have of our slimy snail & slug friends? How many species do we know virtually nothing about? Despite having over 1.5 million observations of gastropods in Australia, many species have fewer than 10 records, or no records at all 😯 Code & high-res 📷 👇 🧪🌏📊 #rstats #dataviz

A waffle bar chart showing the taxonomic coverage of gastropod records in the Atlas of Living Australia. The plot shows the number of species in each gastropod suborder with 100+ records, 10+ records, 1+ records or no records at all. In general, there is quite a high proportion of species (between 13% and 36% depending on the group) with fewer than 10 records or no records at all. The waffle chart consists of squares in different shades of purple to show species record count. Each group is shown in a separate bar. The background is a very dark purple. Example images of snails from each suborder group are shown below each bar.

galah 2.2.0 is on CRAN! 📦 🛡️ Authorised users can access sensitive data from the command line 🌏 GBIF gets full support for predicate or DOI queries, new support for the Flemish and Kew Gardens portals 🗂️ We’ve tidied scripts to be more versatile, efficient & consistent galah.ala.org.au/R/ #rstats

Whoa when this invasive mushroom grows on a dead or dying hardwood tree, the fungal diversity of that tree is cut in half (on average) 😯🍄 Spreading across the US & Canada as well as Switzerland, Italy, Hungary, Serbia & Germany, this fungus could have a huge cascading impact on global ecosystems 🧪🌏

If it didn't make bright yellow mushrooms, we probably wouldn't even know golden oyster was reducing fungal diversity on decaying hardwoods worldwide. A very interesting genetic banking endeavor to conserve imperiled native fungi whose ecosystem roles we certainly don't understand yet. 🍄🧪

Awesome dataviz 🤩 So interesting how much variation there is in phrases like "Realistic possibility" compared to "About even" No wonder it's so difficult to use experimental survey data as strong evidence in research. People are too varied at interpreting scales! 🧪 #psychscisky

A really fun dataset for this week's #TidyTuesday, looking at how people interpret different probabilistic statements 📊 There's so many aspects of this to visualise, but I decided make some barcode plots comparing how people from the UK and US responded! #DataViz #RStats #ggplot2

Mirrored bar plot showing the distribution of estimated probabilities for different terms, for US and UK respondents. Will happen is ranked most likely, and almost no chance is least likely. Points highlight the median which are identical for both groups except for may/might happen and highly likely where US medians are higher.

A nice visual, and a worthwhile one to remember when considering gaps and biases in biodiversity data in Australia 🦘🌱 Nearly 70% of the population lives in a greater capital city, meaning that incidental observations of animals and plants outside of those areas are rare and valuable 🧪🌏📊

Love these population density spike maps. (by @researchremora) www.kontur.io/solutions/au...

This population density map of Australia visualizes how most of the population is concentrated in coastal cities like Sydney, Melbourne, Brisbane, and Perth. The interior is mostly uninhabited, with labels like "NO ONE LIVES HERE" emphasizing the vast emptiness. The vertical spikes represent population density, showing the stark contrast between urban centers and the sparsely populated outback.

In one week I'll be talking about tips for reproducible R code and why science would love you to try these tips on your own code too 🧪😍🌏 It's an online talk, so feel free to watch comfortably from your couch. Hope to see you there! @sortee.bsky.social #rstats events.humanitix.com/sortee-webin...

New in Science, Macaques tap to the beat. Very cool study for its main result and its null one: consistent with nearly every other comparative study of music, monkeys don't differentiate beats by their relative strength—which even young children do innately. Monkeys have rhythm but not meter!

Monkeys have rhythm

Synchronizing movements to music is a hallmark of human culture, but its evolutionary and neurobiological origins remain unknown. This ability requires (i) extracting a steady rhythmic pulse, or beat,...

We all want to write good code…but…how? In my talk later today, I’ll give all few tips I’ve learned about good scientific code writing that have really helped me & maybe they’ll help you! Riverbank room 8, 2:50pm #ESA2025
