Biodiversity–food trade‐offs when agricultural land is spared from production

open access: yesAmerican Journal of Agricultural Economics, Volume 108, Issue 1, Page 254-284, January 2026.
Abstract Biodiversity conservation in agricultural landscapes, the world's predominant land use, could involve sparing, or setting aside, agricultural land from production, implying biodiversity–food trade‐offs. Employing bird species and agricultural data in two panel data sets, we evaluate the extent of set‐aside's trade‐offs in England between 1992 ...

Tridiagonal Symmetries of Models of Nonequilibrium Physics

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2008
We study the boundary symmetries of models of nonequilibrium physics where the steady state behaviour strongly depends on the boundary rates. Within the matrix product state approach to many-body systems the physics is described in terms of matrices ...

The Relationship Between Pre‐ and Post‐Migration Self‐Employment: Evidence From Italy and Spain

open access: yesInternational Migration, Volume 64, Issue 1, January 2026.
ABSTRACT The home‐country self‐employment hypothesis, widely accepted in migration research, posits that immigrants from countries with high self‐employment rates are more likely to become self‐employed. However, supporting evidence remains limited. Recent studies highlight the importance of individual pre‐migration experience, but such evidence is ...

Spatiotemporal Diversification of Forest Understorey Species Reveals the Existence of Multiple Pleistocene Forest Refugia in Central Europe

open access: yesMolecular Ecology, Volume 35, Issue 1, January 2026.
ABSTRACT During Pleistocene cold stages, European temperate forests were not only restricted to refugia in the southern European peninsulas. Rather, there is increasing evidence for the survival of trees also in isolated patches further north, termed ‘northern refugia’.

Module structure of Weyl algebras

open access: yesJournal of the London Mathematical Society, Volume 113, Issue 1, January 2026.
Abstract The seminal paper (Stafford, J. Lond. Math. Soc. (2) 18 (1978), no. 3, 429–442) was a major step forward in our understanding of Weyl algebras. Beginning with Serre's Theorem on free summands of projective modules and Bass' Stable Range Theorem in commutative algebra, we attempt to trace the origins of this work and explain how it led to ...
