Interested in this as a way to extend my R / RShiny skills beyond the academic realm of ecology. I can't DM you but will check back for further updates!

# unz() lets you connect to a .zip and treat it like a mini file system, # and you can load files from inside it one_zipped_csv_among_others <- readr::read_csv( unz("lotsa_zipped_csvs.zip"), "one_csv.csv" ) # readr::read_csv() can read a .zip with a single CSV in it one_zipped_csv <- readr::read_csv("big_zipped_file.zip")

Thing I just learned in #rstats: unz() lets you connect to a .zip and load files from inside it without actually unzipping it (great for a file I'm working with that's 30 MB zipped and 1+ GB unzipped, with multiple CSVs in it)

position_jitter()

position_jitter_ellipse()

position_sunflower()

position_circlepack()

New visualization tool alert!

The vayr package version 1.0.0 is now on CRAN.

It contains position adjustments for ggplot2 that help with overplotting in pleasing ways. My favorite is position_sunflower().

Sadiah Qureshi in conversation with David Olusoga about extinction Manchester Histories presents an 'In Conversation' event marking the launch of 'Vanished: An Unnatural History of Extinction' (Penguin 2025)

Join @davidolusoga.bsky.social and Philip Leverhulme Prize winner @sadiahqureshi.bsky.social in conversation this June as they explore the themes of Qureshi’s powerful new book, Vanished: An Unnatural History of Extinction.

The cover of a board game review in the "Books and Arts" section of the science journal, Nature. The page is mostly taken up by a large color photo of the game board, which features detailed pictures of fish cards. The title of the review is "This board game lets you dip into marine ecology".

Had a lot of fun reviewing the #boardgame #Finspan w/
@oschwery.bsky.social for @nature.com!

This fish-themed game harnesses some of my favorite aspects of #Wingspan, blending stunning art & trophic ecology with fast-paced play.

I’ve long used FiveThirtyEight’s interactive “Hack Your Way To Scientific Glory” to illustrate the idea of p-hacking when I teach statistics. But ABC/Disney killed the site earlier this month :(

So I made my own with #rstats and Observable and #QuartoPub ! stats.andrewheiss.com/hack-your-way/

Map of global lake distribution, colored by the number of SWOT overpasses per 21 day cycle. There are many lakes with a high number of SWOT overpasses at high northern latitudes, but there are also tens of thousands to more than a million lakes on every continent. Lakes are graphed by latitude and longitude on the edges of the figure.

Do you work on lakes globally? Check out what is, to my mind, the most complete global database of lakes (~6M) and associated attributes, newly published in WRR. Also the basis for SWOT lake data. agupubs.onlinelibrary.wiley.com/doi/full/10....

This ridgeline plot and the unconventional use of shading from white to blue to indicate sea ice loss is great. It also reinforces the impression of a dense ice pack breaking up.

Potential and unrealistic conservation gains for terrestrial and marine vertebrates. We define as low vs. high conservation gains (x-axis) the bottom vs. top-ranked (10%) unprotected areas for the conservation of vertebrates according to themaximisation of species range size coverage on land (a birds and mammals) and sea (b fish).We define aspotential vs. unrealistic conservation gains (y-axis), the unprotected areas being the most likely (‘low-hanging fruits’) vs. unlikely (‘highhanging fruits’) to be protected according to their social-environmental context. On global maps, established protected areas are in green, while we only represent the potential vs. unrealistic high conservation gains on land (c) and sea (d). The gradient of colours corresponds to the relative likelihood that these unprotected areas are turned into protected areas according to the 14 social-environmental factors (Tables 1 and 2) and Random Forest models (see ‘Methods’). So, potential high conservation gains are in dark blue,while unrealistic high gains are in dark red. See Fig. 5 for the average relative likelihood of PA establishment per country on land and sea. These patterns could be biased by missing PAs in theWord Database on Protected Areas. Source data and codes are provided at https://doi.org/10.5281/ zenodo.11183846.
