Lithic Miniaturization Provides a Signature of an MIS4‐3 Southern Dispersal of Homo sapiens

open access: yesEvolutionary Anthropology: Issues, News, and Reviews, Volume 35, Issue 1, March 2026.
ABSTRACT Fossil and artefactual evidence shows Homo sapiens in Eurasia well before 75 ka. However, genetic evidence suggests all extant non‐African populations derive almost all of their ancestry from a dispersal that only diverged in the last 60–50 ka. In northern Eurasia, the Upper Paleolithic with its laminar blade knapping provides an archeological

Groundwater Dependency and Hydroclimatic Influences on Riparian and Upland Vegetation Productivity, Upper San Pedro, Arizona, United States

open access: yesHydrological Processes, Volume 40, Issue 3, March 2026.
Remotely sensed vegetation condition is most sensitive to groundwater variability during monsoon seasons, when precipitation is abundant and plants are most productive. Compared to the surrounding uplands, riparian (groundwater dependent) vegetation greenness is more sensitive to vapour pressure deficit, but similarly sensitive to precipitation ...

Global Comparison of Aqueous Geochemistry and Dissolved H2/CH4 in Continental Low Temperature Serpentinization–Influenced Environments

open access: yesHydrological Processes, Volume 40, Issue 3, March 2026.
Conceptual diagram of hydrological and geochemical processes within the Santa Elena Ophiolite, Costa Rica. It highlights watershed cross‐sections, soil genesis, hyperalkaline Type II waters (pH > 11.6) with calcite crust and trapped H2/CH4 gases, seepage into surface waters, storm‐impacted stream profiles, weathered vs.

Water Oxygen Isotope Thermometer in Headwaters: Indicating Groundwater Recharge and Peatland Water Dependence on Air Temperature

open access: yesHydrological Processes, Volume 40, Issue 3, March 2026.
Stable isotopes in water act as natural tracers of precipitation temperature. In mountainous environments, the oxygen isotopic signature measured in stream water reflects air temperature during precipitation events. Oxygen‐isotope‐derived temperatures are closely linked to recharge processes, particularly in peatlands, as well as in groundwater systems.
