Synchrotron multimodal imaging in a whole cell reveals lipid droplet core organization. [PDF]

J Synchrotron Radiat, 2020
Cryo soft X‐ray tomography and deep‐ultraviolet transmittance imaging reveal partitioning of neutral lipids in a lipid droplet core. Furthermore, deep‐ultraviolet transmittance and tryptophan/tyrosine auto‐fluorescence multimodal imaging on living cells were combined to obtain complementary information on organelle chemical contents.A lipid droplet (LD)

Symbiont Reintroduction Alters Tumor Progression and Life-History Traits in the Tumor-Bearing Freshwater Cnidarian <i>Hydra oligactis</i>. [PDF]

Ecol Evol
We reintroduced the native ciliate Kerona pediculus into long‐term symbiont‐free Hydra oligactis lines differing in tumor affliction. Unexpectedly, spontaneous tumors arose at high frequency independently of ciliate acquisition, fundamentally reshaping the experimental framework and enabling comparisons of how symbiont reintroduction affects hosts with

Consequences of Cancer on Zebrafish <i>Danio rerio</i>: Insights Into Sex Determination, Sex Ratio, and Offspring Survival. [PDF]

Ecol Evol
We investigated how cancer influences reproductive traits in zebrafish (Danio rerio), focusing on sex determination, offspring sex ratio, and juvenile survival. While embryonic cancer induction did not affect sex ratios, we found that tumor‐bearing females produced more offspring with higher survival rates, suggesting enhanced maternal investment under

The complex effects of modern oncogenic environments on the fitness, evolution and conservation of wildlife species. [PDF]

Evol Appl
Abstract Growing evidence indicates that human activities are causing cancer rates to rise in both human and wildlife populations. This is due to the inability of ancestral anti‐cancer defences to cope with modern environmental risks. The evolutionary mismatch between modern oncogenic risks and evolved cancer defences has far‐reaching effects on ...

Negation in Contact: French and Occitan

Transactions of the Philological Society, Volume 121, Issue 3, Page 444-459, November 2023., 2023
Abstract Development of negative markers along the lines of the well‐known Jespersen's Cycle occurred in a wide number of languages. This article investigates the possibility of contact playing a role in such developments in Lengadocian Occitan. The evolution of negation in Lengadocian Occitan followed two main lines.

A materialist take on minoritization, emancipation, and language revitalization: Occitan sociolinguistics since the 1970s

Journal of Sociolinguistics, Volume 27, Issue 4, Page 327-344, September 2023., 2023
Abstract This paper introduces and discusses Occitan sociolinguistics as it evolved from the 1970s onward as a theory of language contact as conflict. It was developed in conjunction with its Catalan counterpart and as a reaction to Joshua Fishman's allocational model of diglossia, and came as a response to conditions of swift social and linguistic ...

Home‐rule versus non‐territorial autonomy? Western European national movements and their views on the minority question, 1919–1939

Nations and Nationalism, Volume 29, Issue 2, Page 482-497, April 2023., 2023
Abstract The leading elites of the ethnonationalist movements that developed in the aftermath of World War I in Western Europe usually refused to see their nations and territories as ‘national minorities’. In their view, they were stateless nations or nationalities.

A review of the methods used to induce cancer in invertebrates to study its effects on the evolution of species and ecosystem functioning

Methods in Ecology and Evolution, Volume 13, Issue 9, Page 1885-1898, September 2022., 2022
Abstract Cancer is an understudied but important process in wildlife that is predicted to have a significant effect on the evolution of metazoan species due to negative effects on host fitness. However, gaining understanding of the impact of cancer on species and ecosystems is currently relatively slow as the development of both animal models in which ...

Cântecul Gintei Latine: Vasile Alecsandri, ‘race’ connections and the Latinity of the Romanians (1850s–1870s)

Nations and Nationalism, Volume 28, Issue 3, Page 909-923, July 2022., 2022
Abstract This article reconstructs Vasile Alecsandri's political and cultural activities at an international level, as he attempted to raise public awareness (particularly in France and Italy) for the Romanian national cause, namely, by staking claim to the ‘Latinity’ of Romanians.

On the necessity of combining ethnobotany and genetics to assess agrobiodiversity and its evolution in crops: A case study on date palms (Phoenix dactylifera L.) in Siwa Oasis, Egypt

Evolutionary Applications, Volume 13, Issue 8, Page 1818-1840, September 2020., 2020
Abstract Crop diversity is shaped by biological and social processes interacting at different spatiotemporal scales. Here, we combined population genetics and ethnobotany to investigate date palm (Phoenix dactylifera L.) diversity in Siwa Oasis, Egypt.
