"The statistical fragility of animal cognition findings: a meta-meta-analytic reappraisal"
doi.org/10.32942/X2Z...
Statistical performance of animal cognition meta-analyses at the primary-study and meta-analysis levels. (a) Statistical power: Median power to detect the (true or bias-corrected) meta-analytic effect size; darker red bars indicate lower power. (b) Type M error: Median exaggeration ratio between estimated and true effect sizes; darker blue indicates stronger overestimation (values > 20 shown as “20+”). (c) Type S error: Median probability of obtaining a significant effect in the wrong direction; darker yellow-green indicates higher Type S error. Violin plots above each panel summarise distributions across meta-analyses. Each point represents one meta-analysis (matching a row in the bar plots), and the horizontal line denotes the overall mean.

Do you get confused when reading meta-analyses? Our new paper offers a practical guide to help researchers understand, interpret, and use them properly. We also show that the insights meta-analyses provide are often overlooked by those who cite them.

UPDATE: I saw it happen! At the Birds Canada research station at the tip of Long Point I watched an expert ever-so-gently and carefully put one of these tiny tags on a monarch. Let me walk you through the steps (1/4)

So cool to visit the Motus workshop at Birds Canada headquarters. The Motus community is studying the movement of birds, bats and insects. This tiny radio telemetry device will fit on a Monarch butterfly 😲 #invertebrates #birds 🌿 www.birdscanada.org/bird-science...

Absolutely nobody asked for this but I reformatted my animal yeetability thread into printable poster & zine files.

Introducing, the "Pocket Guide to Responsible & Sustainable Animal YEETING" featuring a revamped rating system. Download links below.
Poster showing various animals and their yeetability rating. For full rating, see the link in the reply. Intro text reads: POCKET GUIDE TO RESPONSIBLE & SUSTAINABLE ANIMAL YEETING by franzanth In this context, YEETING is defined as the act of throwing a “projectile” at a slightly upward angle with low initial velocity. The goal here is relocation, not destruction. Therefore, YEETING is ideally performed toward soft surfaces like leaves to minimize downward acceleration that might result in said projectile's discomfort.

let me share a little story about a remarkable wasp that I encountered yesterday in our local deserts

I stumbled across her, and scrambled to get a few crappy photos .... but then realized that she had a burrow, perhaps a better photo op was possible ??

here she is at her burrow entrance.

Insect populations are rapidly declining even in relatively undisturbed landscapes, raising concerns about the health of ecosystems that depend on them.

🕷️#Arachnews alert! 🦂
New Foelix (the definitive reference for general spider biology, a must-have for every arachnologist & arachnophile) just dropped.

Now called Spider Biology, this is an completely rewritten & updated version of the Biology of Spiders (2011).

Our study, conducted with great care and attention, is out! It went through a meticulous community peer-review process under open science practices, and I’m proud to be part of it. The results may not be what we hoped for, but they are what we need to move toward real inclusivity in science. 💜

No one does fancy appendages quite like treehoppers. Here's a particularly spectacular one, likely in the Genus Hypsauchenia.

The thing about entomology is, there are always weirder bugs than anything you could imagine on your own.

Here's Cysteodemus wislizeni, a blister beetle from west Texas.
Photograph of a metallic blue/green beetle with a very spider-like body, a huge fake "abdomen" that is swollen and dented with even pits over its bulbous surface. It is otherwise ant-like, standing on a pure white stylized background.

In news we all know – but the Government seems to like ignoring – it'll help to fund more basic science research!

Reminder: Nobel-prize winning PCR (1983), used in basically all genetic tech today, was only possible because of extremophile bacterium discovered in 1964 in Yellowstone funded by a small ~$80k NSF grant with no obvious application at the time. #science 🧪
