Strategic materials and state capacity in Renaissance Italy. The economic policies of ‘Roman saltpetre’ procurement

open access: yesThe Economic History Review, EarlyView.
Abstract Demonstrating the existence of a soaring demand for strategic materials in fifteenth‐century Rome, the article pioneers research in the late medieval trade in saltpetre, the irreplaceable, rare component of gunpowder, indispensable for waging war following the diffusion of artillery technology.

Prediction of organic acid concentration in BRS Capiaçu elephant grass silage

open access: yesGrassland Science, EarlyView.
Abstract This study aimed to develop prediction models for organic acid concentrations in Capiaçu grass (Pennisetum purpureum Schum) silage, based on fermentation parameters and chemical composition. Data were obtained from an experiment that evaluated BRS (Brazil Seeds) Capiaçu grass silage with the inclusion of dehydrated cashew pseudofruit ...

Free‐living Black‐tailed Godwits maintain constant intake rates across varying grassland habitat conditions by adjusting their foraging behaviour

open access: yesIbis, EarlyView.
Free‐living birds need to acquire enough food to fulfil their energetic needs, which may require more effort in habitats with less favourable conditions. Therefore, to maintain their necessary energy intake, birds need to adjust their foraging behaviour in response to varying habitat conditions.

The Ambiguous Ecologies of Agri‐Alternatives: Exploring the Calculus of Social Reproduction in Rural India

open access: yesJournal of Agrarian Change, EarlyView.
ABSTRACT This paper advances scholarship on agri‐alternatives by probing the gap between romanticised narratives of how alternative farming transitions ought to be and the actual practices farmers enact in their fields. Focusing on moments when such alternatives encounter on‐the‐ground realities, we propose ambiguous ecologies as a lens to explore the ...

Tending to the Particular: Navigating Tensions Around Principles of Alternativity Through an Ethics of Care

open access: yesJournal of Management Studies, EarlyView.
Abstract Alternative organizations must continuously address conflicts that emerge regarding diverging prioritizations and interpretations of autonomy, solidarity, and responsibility. We explore how tensions around alternative moral principles can be navigated through relational processes that attune to others' needs, emotions, and concerns.

Integrative taxonomy supports DNA barcoding in revealing an abundant cryptic species in the United States Coastal Plain

open access: yesJournal of Systematics and Evolution, EarlyView.
We present the most densely sampled phylogeny of Carex section Lupulinae to date (107 specimens) and describe herein a new cryptic species for science from the southern United States, which is locally abundant and found in well‐explored and densely populated areas. Combining DNA sequences with morphometric data obtained from 299 samples, we Demonstrate

Full‐length coding sequence analysis of the voltage‐gated sodium channel and acetylcholinesterase genes reveals target‐site mutations and acetylcholinesterase gene duplication in housefly (Musca domestica) populations in Japanese livestock barns

open access: yesMedical and Veterinary Entomology, EarlyView.
We simultaneously analysed insecticide resistance mutations in VGSC and AChE using NGS and hybridization probe capture in houseflies collected from livestock facilities for the first time. Resistance mutations in both VGSC and AChE were detected in most wild populations, suggesting widespread distribution of resistance genes.
