To find out, plant physiologist Bert Drake monitors plants used in his CO2 study at the Smithsonian Environmental Research Center (SERC) near the Chesapeake Bay in Maryland.](/sites/default/files/styles/full_width_large/public/2023-11/A_SERC-CO2-Field-site_HR_0.jpg.webp?itok=qZbE8yGy)
CO2 Marsh Study
Credit: Kimbra Cutlip/Smithsonian InstitutionHow do plants respond to rising CO2 levels? To find out, plant physiologist Bert Drake at SERC exposed marsh plants near the Chesapeake Bay to CO2 levels expected in 50 and 100 years. Different species and ecosystems respond differently—leaving uncertainty about the ability of plants to act as effective buffers against increases in atmospheric CO2. Learn more about Dr. Drake’s long-running field study.

![Salps are tube-shaped, soft, transparent animals that swim through the ocean, straining out plant food as they go.](/sites/default/files/styles/full_width_large/public/2023-11/Collabs-in-Action-12_0.jpg.webp?itok=EV0x4LsO)
Antarctic Salps
Credit: Lawrence Madin, Woods Hole Oceanographic InstitutionClimate and sea changes in the Southern Ocean create conditions that favor the growth of salps over krill, the latter of which are a vital food source for seals, whales, and penguins. Salps are filter-feeding tunicates that float through the water column, sometimes forming long salp chains, consuming phytoplankton and using jet propulsion to move. Read about their complex life history in “The Watery World of Salps," by Larry Madin of the Woods Hole Oceanographic Institution. Head to our blog to learn about how non-native tunicates and other marine invasive species are threatening Alaska's coastline.
