Probabilistic modelling improves relative dating from gene phylogenies

Methods 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

Methods 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 ...

Chromosome‐scale reference genome of Pectocarya recurvata, the species with the smallest reported genome size in Boraginaceae

Applications in Plant Sciences, Volume 13, Issue 3, May-June 2025.
Abstract Premise Pectocarya recurvata (Boraginaceae, subfamily Cynoglossoideae), a species native to the Sonoran Desert (North America), has served as a model system for a suite of ecological and evolutionary studies. However, no reference genomes are currently available in Cynoglossoideae. A high‐quality reference genome for P.

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

Agricultural 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

Biotropica, 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

Functional 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

Methods 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 ...
