This remains to be the best comic ever made.

I cannot post my slides on Canvas because *checks 📝* that DECREASES the accessibility score of my class on canvas.

That is because the canvas software has a hard time reading slides and assigns it 0 accessibility.

The only solution is to not post them.

The world is backwards in 1 additional way 🙃

As the end of the semester approaches and I feel overwhelmed even with my exceptionally light class load, I'm reminded of the old saying, "Work inevitable expands to occupy the entirety of the time allotted to it"

What is “#pseudopersistence”?

It refers to contaminants like pharmaceuticals or pesticides with short environmental half lives that are continuously observed in ecosystems due to constant replacement from a source. In this case, Cry proteins leach year round from GE crops & detritus. (2/3)

New paper led by #RiceUniversity undergrad Ethan Bull & former PhD student @pedrobd.bsky.social in collaboration with @notredamescience.bsky.social assessing the role of a pseudopersistant contaminant, Cry1Ab leaching from GE crops, on aquatic caddisflies. @entsocamerica.bsky.social

Assessing morphological, developmental, and genetic responses of Hydropsychid caddisflies to Cry1Ab exposure Abstract. Transgenic crops expressing Cry proteins are widely cultivated to reduce crop damage from insect pests. However, Cry proteins can leach from tran

Transgenic crops release Cry proteins into streams.

But what does that mean for aquatic insects?🌱💧🐛

We measured and barcoded 1,800+ caddisflies across 25 streams.

Environmental factors like temperature, land use explained most patterns. Cry1Ab had limited impact.

Same!!!

I legitimately do not understand it. I think it was just some idea some top executive had and everyone had to nod along not to get fired or something.

I will choose a journal over another simply because it does not have graphical abstracts.

Nothing like spending several hours running an alternative statistical method/ different mathematical approach only to find the exact same answer.✖️

Yes, I should be happy. But it feels a bit like wasted time lol

Am I allowed to complain if the journal sat on my paper for 3 months and rejected it without sending it to reviewers because the editor felt like it?

Name and shame? The journal is Biological Reviews.

Our eDNA survey has a US defaultism problem. 🌎

We started getting mysterious "Country" responses like "Jefferson" and "Maricopa."

Turns out people read "Country" and thought "County" which... only makes sense if you assume everyone is American.

We did this to ourselves.🤣

Being In an interdisciplinary field, it is easy to feel dumb because you are a "jack of all trades, master of none"

But that feel is greatly improved when you learn this sentence is often misquoted. The full version is:

"jack of all trades, master of none, but often better than a master of one"🎃

Estimating Organism Abundance Using Within‐Sample Haplotype Frequencies of eDNA Data Environmental DNA (eDNA) provides powerful insights into species presence and community composition but remains limited in its capacity to infer species abundance or population structure. Here, we sh...

🧬 My haplotype paper is out!

We show that deviations between within-sample and population-level haplotype frequencies can be used to estimate how many individuals contributed to an eDNA sample.

No tissue references needed, just metabarcoding data and some population genetics.

Try working with 12S! It is a nightmare out here.

People insist on metabarcoding with 12S.

I cry "no, please, no, I cannot annotate these!"

But the cries are unheard. Family-level annotations follow;
Complaints come!

But what can I do? 1 SNP separates two paraphiletic genera.

And pseudogenes...

My high school math teacher was great but convinced I should not become a biologist because "my math intuition would be wasted!"

I just got a paper accepted with 10 equations plus more in the supplement 💀.

Pretty sure he would be happy but relieved they are printed and not in my handwriting 😄✍️📄
