Pleistocene Climate Changes and Lineage Diversification of Sphenarium Grasshoppers (Orthoptera: Pyrgomorphidae)

open access: yesEcology and Evolution, Volume 15, Issue 10, October 2025.
We investigate the phylogeographic history and paleodistribution patterns of four closely related grasshopper species of the genus Sphenarium to test the relative impact of Pleistocene climate fluctuations on their diversification. We found that each species responded differently to these fluctuations, but their divergence, distribution, and ...

The influence of hydrological seasonality and land use and cover on the relationship between dissolved organic carbon and carbon dioxide along a karst‐draining large tropical river

open access: yesLimnology and Oceanography, Volume 70, Issue 10, Page 2858-2871, October 2025.
Abstract The partial pressure of carbon dioxide (pCO2) in rivers is influenced by carbonate weathering, soil CO2, photosynthesis, and the mineralization of dissolved organic carbon (DOC). In tropical regions, elevated temperatures intensify these processes. However, their seasonal dynamics remain poorly understood in large karst‐draining rivers.
