‘Civilizing’ Smallholders Through Oil Palm: The Politics of Subsumption Across Southern Mexico's Commodity Frontiers

Journal of Agrarian Change, EarlyView.
ABSTRACT While most frontier studies associate commodity expansions with dispossession, I argue that such expansions can also function as ‘civilizational’ projects aimed at overcoming traditional farming and creating new rural subjects better suited to the needs of capitalist development. Using a Gramscian approach to study subsumption, I analyse three

A synthetic eco‐evolutionary proposal for the conservation of wild relatives of the olive tree

PLANTS, PEOPLE, PLANET, Volume 8, Issue 5, Page 1904-1924, September 2026.
Societal Impact Statement Crop wild relatives (CWR) are valuable sources of genetic diversity for plant breeding. However, the identification of wild untapped genetic resources (i.e., unexploited in crops) is not always straightforward. We propose a methodology to guide the identification and conservation of these resources that integrates both genetic

Blurring Migrant Solidarity: Navigating the Troubled Regime of ‘Helping Others’ From the Urban Ground of Palermo

Area, Volume 58, Issue 2, June 2026.
ABSTRACT This paper explores migrant solidarity in the aftermath of the 2015 so‐called ‘migration crisis’ from the ground of the Southern Italian ‘solidarity city’ of Palermo, building on ethnographic material collected across 2022/2023. It argues that migrant solidarity both resists and reproduces racialised borders, as it is never entirely and ...

Exploring the Neural Substrates of Number Sense: A Perspective on Genetics, Behaviour and Neural Circuity

European Journal of Neuroscience, Volume 63, Issue 8, April 2026.
Numerical cognition arises from conserved mechanisms linking genes, neural circuits and behaviour. Using zebrafish as a tractable model, behavioural assays, whole‐brain imaging and genetic analyses can be integrated to identify neural and molecular bases of quantity discrimination. This framework provides a platform for studying numerical cognition and

Euphorbia balsamifera subsp. adenensis (Euphorbiaceae) new to Socotra and notes on its taxonomy

Nordic Journal of Botany, Volume 2025, Issue 9, September 2025.
Euphorbia balsamifera Aiton has been treated since 1965 as a disjunct species with two subspecies, subsp. balsamifera in the Canary Islands (Spain) and adjacent parts of northwestern Africa, and subsp. adenensis (Deflers) P.R.O.Bally in southwestern Asia and northeastern tropical Africa. However, in 2021, E.
