Occurrence and evolutionary inferences about Kranz anatomy in Cyperaceae (Poales)
Anais da Academia Brasileira de Ciências, 2015 Cyperaceae is an angiosperm family with the greatest diversity of species with Kranz anatomy. Four different types of Kranz anatomy (chlorocyperoid, eleocharoid, fimbristyloid and rhynchosporoid) have been described for this angiosperm family, and the ...

The ecology of attraction: Fruit traits and frugivore diversity in neotropical Piper
Functional Ecology, Volume 40, Issue 3, Page 611-623, March 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Fruit traits can benefit plant reproduction by enhancing seed dispersal by mutualistic frugivores (e.g. seed dispersal syndromes), but identifying the role of specific fruit traits in mediating frugivory is challenging because these traits can serve multiple functions ...

Global Change Biology, Volume 32, Issue 1, January 2026.Forest conversion for agriculture is a major cause of biodiversity loss in the tropics, but its impacts depend on how broadly they are measured. Using data from across Colombia, one of the most biodiverse countries in the world, we examined how deforestation for cattle farming affects the evolutionary history of bird species.

Systematic Entomology, Volume 51, Issue 1, January‐March 2026.A subgeneric classification is proposed for Triepeolus—the second‐largest genus of cleptoparasitic apid bees in the world—and its sister genus Epeolus, with support from a newly presented dated phylogeny. Phylogenomic analysis based on ultraconserved elements revealed strong support for the monophyly of Triepeolus, which diverged from Epeolus sometime ...

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.
