Advances in high‐resolution cryo‐volume electron microscopy (cvEM) imaging for unicellular and multicellular organisms

open access: yesJournal of Microscopy, EarlyView.
Abstract Cryo‐Focused Ion Beam Scanning Electron Microscopy (cryoFIB‐SEM) using samples fixed by high‐pressure freezing uniquely enables high‐resolution cryo‐volume Electron Microscope (cvEM) images of cell ultrastructure to be obtained from whole cells and complex tissues in their near native state. As the freezing process also preserves fluorescence,

Corsican Bronze Age fortifications: settlements, economic centers, and/or power places?

open access: yesIpoTESI di Preistoria
The fortified settlements (casteddi) of the Corsican Bronze Age are among the most defining elements of the island's protohistoric landscape. Their monumentality alone, characterized by massive architecture and remarkable elevations, justifies their ...

Melanism in salamanders: effects of insularity, sex and size on dorsal colouration in Salamandra salamandra

open access: yesJournal of Zoology, EarlyView.
In this study we tested the effects of insularity on amphibian colouration using the fire salamander as a model system. Although increased melanism was not a consistent pattern across all islands, salamanders from one island exhibited higher proportions of black pigmentation than mainland populations, while insular populations overall showed reduced ...

Economic Dependencies and Nationalist Divergences: Public Versus Private Sector Employment and Beyond in Corsican Separatist Nationalism

open access: yesNations and Nationalism, EarlyView.
ABSTRACT Separatist nationalism often persists in divided minority regions where internal factions struggle to agree on governance models, perpetuating conflict and political tension. This article examines the key structural and situational factors driving these divisions in Corsica, focusing on economic dependencies that shape divergent approaches to ...

Claiming the Isle? Islandness and Territorial Demands

open access: yesNations and Nationalism, EarlyView.
ABSTRACT This article explores the relationship between insularity and territorial demands, focusing on whether island territories are more likely to support regionalist and secessionist parties. To address this question, we compare electoral support for such parties across island and mainland territories using a large‐N dataset.

Preschool Duration, Family Background and Long‐Term Outcomes: Evidence From the Expansion of École Maternelle in France

open access: yesOxford Bulletin of Economics and Statistics, EarlyView.
ABSTRACT This paper analyses the long‐term effects of preschool education in France. We focus on the effect of preschool duration on educational attainment and labour market earnings in adulthood. Building on an old tradition of free and universal pre‐primary education, France implemented in the late 1960s a large‐scale expansion of preschooling ...

The Heterogeneous Regional Employment Effects of Environmental Policies

open access: yesOxford Bulletin of Economics and Statistics, EarlyView.
ABSTRACT This paper examines the effects of Environmental Policies—measured by the OECD Environmental Policy Stringency Index (EPS)—on employment in 349 regions across 26 countries from 1990 to 2020. We find that more stringent EPS have short‐term negative effects on regional employment, which disappear in the medium term.

Wildland Fire Behaviour Case Studies and Fuel Models for Landscape-Scale Fire Modeling

open access: yesJournal of Combustion, 2011
This work presents the extension of a physical model for the spreading of surface fire at landscape scale. In previous work, the model was validated at laboratory scale for fire spreading across litters.

Ibero‐Balearic plant disjunctions: genomic support for rapid and recurrent long‐distance colonizations of the endangered Diplotaxis ibicensis (Brassicaceae) despite no dispersal syndromes

open access: yesPlant Biology, EarlyView.
Genotyping‐by‐sequencing data reveal six well‐defined clades in the endangered Diplotaxis ibicensis, endemic to the western Mediterranean Basin and indicate rapid and recurrent long‐distance colonisations across the Balearic Islands and the eastern Iberian coast despite the absence of dispersal syndromes.

Vegetation trajectories over 150 years of temporary ponds created in the Camargue delta (Southern France)

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Temporary ponds in the Mediterranean climate have a high conservation value, but many have been severely destroyed or degraded. Pond restoration and new pond creation have been engaged widely. Evaluations of the success of such operations are generally carried out over 10–15 years and show divergent results over this timeframe. In
