June 11 -27, 2026, I'm teaching a 16-day field course on stream ecology. It's heavily focused on independent research projects, so they get some exposure to field research. Open to students from any institution. DM with your email if you want a poster to send your students. #Ecology #PUI #insects

The Geological Society of America is hosting their annual conference in SA this year & because of that they're also hosting a bunch of fun field trips for interested nerds.

I'm excited to get a hands-on exploration of the Edwards Aquifer hydrology with experts, & its history with the building of SA

A screenshot of one of the tours being offered by GSA this month. It's titled "Building San Antonio: Geology, water and building resources in the historic 'Valley of the Missions'". Above the title is a day-time photo of Mission San José y San Miguel de Aguayo (usually just called Mission San Jose)

A screenshot of one of the tours the GSA is offering this month. It's titled "The Edwards Aquifer of South-Central Texas - An Aquifer Under Stress". Above the title is a day-time photo of typical Balcones Escarpment flora, with a creek running through a lush riparian area.

Side note, the Comal Springs in what is now New Braunfels, Texas, are the largest springs in the Southwestern US; and I heard that San Pedro Springs in whats now San Antonio, at one time gushed so powerfully that it had a fountain like effect, where it would spurt into the air.

A screenshot of one of the tours the GSA is offering this month. It's titled "The Flow of Sustainability: Inside the San Antonio Water System (Wednesday Afternoon)". Above the title is a day-time photo of the San Antonio Water System (or SAWS) headquarters building.

A screenshot of a tour being offered by the GSA this month. It's titled "Bracken Cave Bat Flight". Above the title is a photo of a bat (probably a Mexican Free-tailed (or Freetail) Bat) hanging upside-down from a rock, assumedly in a cave.

Side note, Bracken Cave is actually home to about 20 million bats a year (!), due to migratory patterns. I've heard it called the largest concentration of mammals (excluding Humans) in the world!

The Geology Dept at WWU is hiring an Assistant Prof in Hydrology! Come be my colleague in a great department! More info in the attached flyer, and at hr.wwu.edu/careers-facu...

Assistant Professor of Hydrogeology

About Western: Western Washington University, with over 15,000 students in seven colleges and the graduate school, is nationally recognized for its educational programs, students and faculty. The campus is located in Bellingham, Washington, a coastal community of 90,000 overlooking Bellingham Bay, the San Juan Islands and the North Cascades Mountain range. The city lies 90 miles north of Seattle and 60 miles south of Vancouver, British Columbia. Western has additional sites in Anacortes, Bremerton, Everett, Port Angeles, and Poulsbo. Western is recognized nationally for its successes, such as being named one of the top public master's-granting institutions in the Pacific Northwest for 25 years in a row by U.S. News & World Report.

About the Geology Department: The Geology Department has 17 faculty, offering BA, BS and MS programs in Geology, Geophysics, and Science Education, serving approximately 190 majors. The department has strengths in field and lab-based teaching and research in geomorphology, igneous petrology, geophysics, hydrogeology and envionmental/engineering geology, planetary geology, sedimentology, science education, and structure/tectonics.

Additional information about our programs can be found at https://geology.wwu.edu/. The Geology Department strives to further Western's identity as an institution that welcomes and embraces diversity and encourages applications from diverse candidates.

About the Position: The ideal candidate will support our department's ability to produce workforce-ready geoscientists. We seek individuals who are enthusiastic about teaching and who will establish a productive research program that involves undergraduate and Master's-level students. Broad areas of research interest may include, but | are not limited to, groundwater-surface water interactions, environmental hydrogeology, and groundwater systems (e.g-geothermal, fault zone, coastal, mountain). Teaching responsibilities will in…

Two paths diverged in a wood, and I–
I took the one more traveled by;
Because the wood is still a full ecosystem and leaving the maintained path can damage it,
Also I don't want ticks or wet socks

"Early cultivation studies skewed toward microbes with bigger genomes and broader metabolisms—laboratory generalists that grow on rich media. As single-cell genomics, metagenomics, and long-read assemblies matured, they revealed the prevalence of the svelte specialists in the wild." 🌐🧪

Moderate warming may not reduce soil carbon storage in humid subtropical forests, as sustained plant inputs and microbial adaptation can support continued carbon accumulation under such conditions. doi.org/g96qt3

Moderate warming may not doom humid subtropical forests' carbon storage

A new study has challenged the long-standing assumption that global warming will inevitably turn humid subtropical forests into carbon sources, revealing these ecosystems may instead continue accumulating soil carbon under moderate temperature rises.

As landscapes dry, multifunctionality holds—until a threshold. Below it, microbial yield traits steady the system; beyond it, acquisition and stress strategies take over, and EMF falls. Decomposition and habitat functions are last to bend under aridity. 🌐🧪

Across 1984–2023 in the Western USA, post-fire flow changes were statistically insignificant and uncorrelated with burn extent. Control-pair tests show paired-watershed methods often miss hidden covariates; uncertainty can exceed observed effects. Pre-fire forest cover showed only weak links. 🌐🧪
