Filogenia del género Syncirsodes (Lepidoptera: Geometridae)

open access: yesRevista Colombiana de Entomología, 2016
Se determinó la filogenia de Syncirsodes Butler, sobre la base de caracteres morfológicos. Las especies incluidas son: S. distictaria, S. hyadesi, S. primata y S. straminea. Se usaron 27 caracteres morfológicos de estructuras externas e internas de adultos, con énfasis en la genitalia de machos y hembras y en el metafurcaesterno.

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.

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

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.

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 ...
