ENHYDROSS: A New Mechanistic Model Supports the Trans‐Oceanic Dispersal Capability of Terrestrial Vertebrates

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
We introduce ENHYDROSS, a new mechanistic model that uses optimal swimming speed and minimum cost of transport to estimate maximum dispersal distances and durations for vertebrates, enabling assessment of long‐distance oceanic dispersal potential. Applied to a range of extant and extinct animals, the model's estimates generally align with observed data;

Taxonomic treatment, geographic distribution and preliminar conservation status of Croton sect. Barhamia subsect. Barhamia (Euphorbiaceae) in Brazil

open access: yesNordic Journal of Botany, Volume 2026, Issue 3, March 2026.
The genus Croton (Euphorbiaceae) is an exceptionally megadiverse genus, encompassing roughly 1200 species that are predominantly distributed across tropical regions globally. For the New World, the genus is organized into three subgenera (Adenophylli, Geiseleria and Quadrilobi) and 31 sections, with C. sect. Barhamia standing out with its approximately

Post‐liberalism and the politics of liberation: Brazilian favelas as emergent territories of freedom Postlibéralisme et politique de la libération : les favelas brésiliennes, territoires de liberté émergents

open access: yesJournal of the Royal Anthropological Institute, Volume 31, Issue 4, Page 1023-1040, December 2025.
Brazilian favelas (shantytowns) are often considered as marginalized urban territories that must be better integrated into the nation‐state to obtain legitimacy under the Rule of Law. Based on years of fieldwork in one of the largest shantytowns in Rio de Janeiro (Rocinha), this article suggests that the absence of a (normative) liberal apparatus in ...

Mapping priority areas to mitigate the risk of electrocution of range‐restricted bird species

open access: yesJournal of Applied Ecology, Volume 62, Issue 10, Page 2787-2799, October 2025.
Our study proposes a framework to identify areas with higher electrocution risk, which can be used even in data‐scarce regions or adapted to a multi‐species assessment context. This approach can support proactive strategies for energy companies with an initial assessment identifying areas to avoid installing new power lines, evaluating sites for ...

Intraskeletal histovariability and skeletochronology in an ornithopod dinosaur from the Maestrazgo Basin (Teruel, Spain)

open access: yesJournal of Anatomy, Volume 247, Issue 3-4, Page 643-664, September/October 2025.
Abstract Ornithopods are an extinct group of dinosaurs that were particularly abundant and diverse in the Cretaceous of the Iberian Peninsula, and whose abundance in the Maestrazgo Basin has allowed numerous taxa to be identified over the last decade. Many of these fossil remains are still taxonomically indeterminate and require a more detailed study ...

Solvent‐ and Transition Metal‐Free Mechanochemical Synthesis of 2‐Thiazolines and S‐Thiocarbamates

open access: yesAdvanced Synthesis &Catalysis, Volume 367, Issue 14, July 29, 2025.
Solvent‐ and transition metal‐free synthetic pathways for obtaining 2‐thiazolines and S‐thiocarbamates, based on the mechanochemical process of addition of chloroalkyl iso(thio)cyanates to thiols catalyzed by cheap and commercially available K2CO3, are designed and optimized.
