I just took 5 minutes to send a random email out to someone, just to tell them how much I love their work and why (had just read one of their papers again this am). No agenda. I think we need to normalize borderline gushing fan emails to our colleagues. Keep the motivation!

How do we represent physical drivers of gas concentrations and fluxes in streams, and does scale matter? How are stream slope and k600 effects distinguished? New publication led by Yuseung Shin, in @jgrbiogeo.bsky.social! doi.org/10.1029/2026...

The Effects of Stream Slope on Dissolved Gas Concentrations Are Mediated by Scale in an Example Low‐Gradient Stream
Variation in gas concentrations across a low-gradient stream was not driven by gas exchange despite clear pool-run distinctions Channel slopes at habitat and reach scales were strongly correlated...

I am a mom and scientist begging everyone to look closer at the muck. We’ve been conditioned to see wetlands as wastelands. But three decades of research, I see a fiercely defiant wilderness. The boreal mire is a dynamic carbon-trapping vault that in some places has outlasted ice ages. 1/

As both an academic and a writer, I am repelled by the "this looks like a long document. Would you like me to summarize it for you?" that seems to appear at the top of every pdf viewer now. NO. The *entire point* of good writing (either books or journal papers) is that every sentence has a purpose.

Habitat variability is key to supporting consistent life in braided rivers. New research led by Holly Harris has shown that different parts of the river fluctuate at different times, which smooths out the boom‑and‑bust cycles of insects and fish across the whole river ‘braidplain’.

Franzi Schimmer captured this Grizzly bear in Brooks Falls, Alaska just floating along, tippy-tapping down the river, browsing the salmon. Prior to hibernation, up to 40% of a bear's body mass is fat, which is less dense than water (~0.9 g/cm^2), so the murder-monster is also a floaty-boaty.

Multiple ecology faculty positions at @notredame.bsky.social. Apply at apply.interfolio.com/171650. (1/2). 🌎🌐🧪
Multiple Early Career Faculty Positions in Ecology
 
The Department of Biological Sciences at the University of Notre Dame invites applications for multiple, tenure-track assistant professor positions that will enhance existing institutional excellence in ecology. We are searching broadly for creative and collaborative individuals (1) working at any spatial scale, from local to global, in any system, (2) studying any level of biological organization, from genes to ecosystems, and (3) using any mode of inference, from empirical to theoretical. Applicants should demonstrate research excellence that crosses traditional disciplinary boundaries; ongoing growth in the department will emphasize new hires that use quantitative and/or integrative approaches to study ecological processes. Postdoctoral experience is desirable in applicants. Successful candidates will engage with and benefit from UNDERC, Notre Dame’s 8000-acre environmental field station and home to NEON’s Great Lakes domain, superb on-campus chemical and genomic analytical facilities, an experimental research facility located close to campus, cross-disciplinary interactions through multiple centers and institutes including the Environmental Change Initiative, and a unique Interdisciplinary Graduate Training Program in Environment and Society. New faculty will benefit from Notre Dame’s recent campus-wide Strategic Framework that included the Just Transformations to Sustainability Initiative. Modern research facilities exist in a new environmental research building, which opened in 2025.
