Probabilistic modelling improves relative dating from gene phylogenies

open access: yesMethods in Ecology and Evolution, Volume 16, Issue 10, Page 2461-2471, October 2025.
Abstract Establishing the timing of past evolutionary events is a fundamental task in the reconstruction of the history of life. State‐of‐the‐art molecular dating methods generally involve the reconstruction of a species tree from conserved, vertically evolving genes and the assumption of a molecular clock calibrated with the fossil record.

PhyBaSE: A Bayesian structural equation model approach to causal inference in phylogenetic comparative analyses

open access: yesMethods in Ecology and Evolution, Volume 16, Issue 6, Page 1136-1148, June 2025.
Abstract One of the main limitations of phylogenetic comparative analyses is that associations between traits can only be interpreted as correlations. Here, we present a novel Bayesian structural equation model (PhyBaSE) which allows us to disentangle direct from indirect relationships among variables to propose potential causal hypotheses while ...

La morfología de la línea de esmalte en los molares de los roedores muroideos es explicada mediante una red hexagonal

open access: yesEstudios Geologicos, 2011
La línea de esmalte observada en la corona de los roedores muroideos tiene formas geométricas que coinciden exactamente con una red plana triangular equilateral. Esta conclusión ayuda a explicar el modelo dental de los muroideos con una nueva perspectiva

Tracing the origin of the alien pest Cydia pomonella in Algeria through a worldwide comparison of the species’ DNA barcodes Reserche de l'origine du ravageur exotique Cydia pomonella en Algérie grâce à une comparaison mondiale des codes‐barres ADN de l'espèce Rastreando el origen de la plaga exótica Cydia pomonella en Argelia mediante una comparación mundial de los códigos de barras del ADN de la especie

open access: yesAgricultural and Forest Entomology, Volume 27, Issue 2, Page 171-181, May 2025.
Cydia pomonella (Lepidoptera: Tortricidae) is a harmful apple and pear pest spread worldwide. We sequenced, for the first time, mitochondrial DNA from C. pomonella caterpillars collected in Northern Africa (Algeria) and assessed where it was introduced from.

Phenotypic, Floristic, and Anthropogenic Drivers of the Pollen Niche of Amazonian Stingless Bees

open access: yesBiotropica, Volume 57, Issue 3, May 2025.
The pollen diversity and composition collected by Amazonian stingless bees depend on their body mass, tree composition, and urbanization. Further, bees have been collecting fewer pollen types since the 1970s. ABSTRACT Stingless bees (Apidae: Meliponini) are major pollinators in the tropics, supporting key ecosystem services.

Phylogenetic conservatism in the relationship between functional and demographic characteristics in Amazon tree taxa

open access: yesFunctional Ecology, Volume 39, Issue 1, Page 181-198, January 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Leaf and wood functional traits of trees are related to growth, reproduction, and survival, but the degree of phylogenetic conservatism in these relationships is largely unknown.

Simpson's tachytely or bradytely? The importance of quantifying rate uncertainty

open access: yesMethods in Ecology and Evolution, Volume 16, Issue 1, Page 4-18, January 2025.
Abstract The spectacular variation in species forms and richness across space and time can be explored using sophisticated and powerful tools recently developed by evolutionary modellers. In this contribution, we ask if the classic ‘Simpsonian’ view of tachytelic (fast), horotelic (standard) and bradytelic (slow) diversification rates can be ...

Quantifying species biases among multidata sources on illegal wildlife trade and its implications for conservation

open access: yesConservation Biology, Volume 38, Issue 5, October 2024.
Abstract Unsustainable wildlife consumption and illegal wildlife trade (IWT) threaten biodiversity worldwide. Although publicly accessible data sets are increasingly used to generate insights into IWT, little is known about their potential bias. We compared three typical and temporally corresponding data sets (4204 court verdicts, 926 seizure news ...

Global distribution range of birds is negatively correlated with their level of diet specialization

open access: yesJournal of Biogeography, Volume 51, Issue 10, Page 2062-2069, October 2024.
Abstract Aim Understanding the factors determining the size of a species distribution range is crucial to preventing the extinction of vulnerable species, particularly specialist species. Previous research has shown that climate and various traits of a species significantly affect its distribution range size.
