Sourcing carnelian beads from the ancient Mesopotamian site of Kish, Iraq, 2450–2200 BCE: Stylistic, technological and geochemical approaches

Archaeometry, Volume 68, Issue S1, Page S22-S37, April 2026.
Abstract Trade between Mesopotamia and the Indus Civilization is studied through the analysis of Early Dynastic III Period (2600–2350 BCE) carnelian beads from the site of Kish, Iraq. Morphological and technological features of the beads are compared with beads from the Indus region.

GeoNav: Enhancing field phenotyping with high‐precision global navigation systems integration in the Field Book mobile application

Crop Science, Volume 66, Issue 2, March/April 2026.
Abstract Field data collection is a key activity in plant breeding, underpinning efforts to develop crop varieties with improved yields, disease resistance, and climate adaptability. Accurately associating data with the correct field plots is critical for selection and genetic improvement but can be challenging, especially in large experiments.

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

Hydrological 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.

Relative pollen productivity estimates from India: A step towards quantitative reconstruction of past plant abundance

Ecosphere, Volume 17, Issue 2, February 2026.
Abstract Pollen records and models of pollen–vegetation relationships are required to reconstruct past plant abundances during the Holocene to answer specific questions on climate history, human impact, biodiversity, and their interactions. An important parameter for model applications is pollen productivity, estimated as relative pollen productivity ...
