ORCHESTRATING DIFFERENCE AND SIMILARITY: Black Fungibility, and the Spatial Redrawing of Racial Categories in Spanish Colonial Morocco, Sahara and Guinea

open access: yesInternational Journal of Urban and Regional Research, EarlyView.
Abstract In this article I dissect the spatial strategies through which the Spanish attempted to orchestrate both racial difference and similarity in the African colonies of Morocco, Western Sahara and Equatorial Guinea during the first half of the twentieth century.

Surveying the Farmer Survey: A Synthesis of Research Practices in the Netherlands, Slovenia and Sweden

open access: yesJournal of Agricultural Economics, EarlyView.
ABSTRACT Research based on farmer surveys is a cornerstone of agricultural economics. Farmer surveys provide unique insights into behavioural variables—such as values, motivations, attitudes, behaviours, and preferences—that are unavailable in secondary datasets.

Rising Tides, Falling Harvests: Examining the Effects of Salinity Intrusion on Paddy Production in Vietnam's Mekong Delta

open access: yesJournal of Agricultural Economics, EarlyView.
ABSTRACT Rising sea levels and salinity intrusion increasingly threaten rice farming in Vietnam's Mekong Delta. Using a district‐level panel dataset from 2000 to 2020, this study examines the impacts of salinity on Winter–Spring rice yields and acreage and how farmers adapt to salinity risk.

Co‐phylogeny and biogeography of the myrmecophilous beetle Paussus favieri (Carabidae, Paussinae) and its host ant Pheidole pallidula (Hymenoptera, Myrmicinae)

open access: yesInsect Science, EarlyView.
Strict patterns of co‐divergence have rarely been documented other than among organisms and their symbionts. In this paper, using a molecular approach, we inferr the population‐level phylogenies of a Mediterranean ant species Pheidole pallidula and its nest parasite, the obligate myrmecophilous beetle Paussus favieri. We then investigate the role of co‐

Ant–aphid mutualism: the influence of Tapinoma ibericum (Hymenoptera: Formicidae) on Aphis gossypii (Hemiptera: Aphidae) control by commercial and spontaneous natural enemies

open access: yesInsect Science, EarlyView.
The mutualism between Tapinoma ibericum ants and Aphis gossypii disrupts the biological control exerted by Aphidius colemani in greenhouse peppers. Ant exclusion increased parasitism and the presence of most natural enemies, although Aphidoletes aphidimyza was more abundant with ants.
