New pub alert #AGUPubs! Small, shallow waterbodies are among the most productive freshwater ecosystems on the planet! In this @GLEONetwork #ponding collaboration, we examined ecosystem metabolism in 26 shallow waterbodies in N. America and Europe. (1/4).

I'm so excited to share some of our new work mapping ponds! PhD student Denghong's remote sensing skills are enviable :) Now he's working on mapping ponds throughout NYS. Stay tuned!.

@GLEONetwork Our study provides more evidence that ponds are truly biogeochemical hotspots! This work was such a fun collaboration years in the making. @JoeRabaey @DRichardsonLab @jbcotner @EvoEcoEric and many more not on here!.(4/4)

@GLEONetwork We also explored how well metabolism models (designed for bigger, deeper lakes) work for ponds. Metabolism models work best in sites that are more productive and have bigger diel oxygen swings. Models performed poorly in less productive / more heterotrophic systems (3/4)

@GLEONetwork We observed high rates of GPP (mean 8.4 g O2 m-3 d-1) and R (mean 9.1 g O2 m-3 d-1), while NEP varied from net heterotrophic to autotrophic. Metabolism rates were affected by depth and plant cover; the shallowest waterbodies had the highest GPP, R, and most variable NEP. (2/4)

#ASLO24 - We welcome your abstract submissions for our special session on the role of macrophytes in aquatic biogeochemical cycles! Hope to see you in Madison this June.

Less than a week to apply for our lab manager position! Apply by 1/21. Contact me directly if you have questions.

This looks like a great read. Climate warming --> browning of northern terrestrial food webs (and it appears to be new C, not old!). Use of museum specimens and experiments. Congrats on the study, @pmanlick!.

Apply by January 21st for full consideration!.

An incredible resource on measuring all things carbon in wetlands and waterbodies.

High plant densities released the most GHGs, likely due to competition + plant die-off. Effects were strongest in the water column, with little effect on sed. production (likely due to limited roots). Plant density may help explain variability + seasonality of aquatic GHGs! (4/4).

We conducted a 2-month mesocosm study where we manipulated C. demersum density (0, 10, 20, or 30 individuals) and measured GHG emissions, GHG concentrations in the surface and porewater, plant growth, and water chemistry. (3/4).

Shallow freshwaters are large sources of greenhouse gases (GHGs) and are often dominated by submersed plants. Yet, the role these plants have in affecting GHG emissions is unclear, especially when considering how variable plant populations are across time and space. (2/4)

We’re excited to share our recent paper examining how the density of a submersed macrophyte (Ceratophyllum demersum) controls aquatic greenhouse gases! This work was developed and led by my grad student, Meredith Theus. (1/4).
