A global estimator of C and N isotope baselines for fresh waters
Methods in Ecology and Evolution, Volume 17, Issue 3, Page 992-1006, March 2026.Abstract Baselines are the pebbles in the shoes of isotope ecologists. The extreme variability of the isotope composition of resources at the base of food webs governs the spatial differences of consumers' isotope composition, so that isotope‐inferred trophic properties can be compared across ecosystems only after correction for baseline effects ...

Limnology and Oceanography, Volume 71, Issue 2, Page 1-14, February 2026.Abstract Diverse environmental drivers influence food web energy and nutrient flows, a key ecosystem function, yet their relative importance remains poorly known. We compiled thousands of bulk stable isotope measurements (carbon and nitrogen) of brown trout (Salmo trutta, n = 2854) and Arctic charr (Salvelinus alpinus, n = 3062) from 120 cold‐water ...

Soap Froths and Crystal Structures
, 2000 We propose a physical mechanism to explain the crystal symmetries found in macromolecular and supramolecular micellar materials. We argue that the packing entropy of the hard micellar cores is frustrated by the entropic interaction of their brush-like ...

Badiou and the Reconstruction of the Concept of God
Modern Theology, Volume 42, Issue 1, Page 187-209, January 2026.Abstract In this article I first summarize Badiou’s and Žižek’s critique of the concept of God, which I and other interpreters conceive as a radicalization of the theology of the death of God. I then pose the question of how to formulate a positive conception of God after the death of God that would overcome the limits of negative or apophatic theology.
