La femme fait la maison: The Accumulation of Surplus Value through Family Planning in Burkina Faso1
Antipode, Volume 58, Issue 1, January 2026.Abstract Since the 1960s, demographers, international donors, and governments have calculated the political, economic, and social benefits of modern contraception usage in West Africa. We evidence how family planning technologies (FPTs) that are tethered to population development extract double value (productive and reproductive labour) from Burkinabè ...

The appearance of Rosenella (stromatoporoid sponge) in Baltica: new species from the Pirgu Stage (Katian, Upper Ordovician) of Estonia [PDF]
Estonian Journal of Earth SciencesThe Katian Age, part of the Late Ordovician Epoch, was a period of significant stromatoporoid diversification. However, their fossil record is often less continuous, hindering our understanding of their diversity and diversification.

δ13C chemostratigraphy in the upper Tremadocian through lower Katian (Ordovician) carbonate succession of the Siljan district, central Sweden [PDF]
Estonian Journal of Earth Sciences, 2014 Based on δ13C data from two drillcores recovered from the Siljan district, we present a first continuous carbon isotope record of the upper Tremadocian–lower Katian limestone succession of central Sweden.

Late Ordovician ironstone and its relation to ocean redox instability, climate and glaciation
Sedimentology, Volume 72, Issue 2, Page 631-665, February 2025.Abstract The Upper Ordovician (Katian) Neda Formation, a phosphatic ironstone, records a widespread but short‐lived shift to ferruginous waters across a vast epicontinental area. Lithofacies and stratigraphic reappraisal indicate that Neda ironstone deposition occurred on a storm‐dominated ramp when coastal upwelling emplaced eutrophic ferruginous ...

Island Arc, Volume 34, Issue 1, January/December 2025.ABSTRACT An ostracod assemblage from the Late Ordovician (Katian) Phu Ngu Formation of northern Vietnam, South China paleoplate, yields typical Baltic and Laurentian‐affinity genera together with some endemic forms. Detailed paleontological and sedimentary analysis of the Phu Ngu Formation suggests it was deposited in a deeper marine forearc setting ...

Bioturbators as ecosystem engineers in space and time
Palaeontology, Volume 67, Issue 6, November/December 2024.Abstract Biogenic sedimentary structures offer a unique perspective for understanding the role of the biosphere in the interaction with other Earth subsystems and the building up of our planet. The record of their ancient equivalents provides a wealth of information for reconstructing the role of bioturbators as ecosystem engineers using multiple ...
