SFA researcher: Chinese tallow leaf litter lowers dissolved oxygen and reduces amphibian breeding in mesocosm trials
Summary
Caleb Mellas, a doctoral student at Stephen F. Austin State University, reported mesocosm experiments showing Chinese tallow leaf litter drove large dissolved‑oxygen declines, lower pH and consistently fewer eggs and tadpoles compared with native leaf types; he said tallow treatments often lacked tadpoles in end‑of‑season surveys.
A doctoral researcher from Stephen F. Austin State University presented mesocosm experiments indicating that Chinese tallow leaf litter alters water chemistry and reduces amphibian breeding success in experimental wetlands.
Caleb Mellas, a doctoral student at SFA, described replicated field mesocosm experiments testing four leaf‑litter treatments (Chinese tallow, Shumard oak, loblolly pine and a no‑litter control) at two concentrations. He told attendees the results showed tallow treatments…
