Contact chemoreceptive mate recognition in Cerambyx welensii Küster (Coleoptera: Cerambycidae) Mediación de la quimiorrecepción por contacto en el apareamiento en Cerambyx welensii Küster (Coleoptera: Cerambycidae)

Agricultural and Forest Entomology, Volume 25, Issue 4, Page 622-636, November 2023., 2023
Abstract Cerambyx welensii Küster (Coleoptera: Cerambycidae) is a wood‐borer responsible for the decline of Mediterranean oaks in open woodlands.

Ecological convergence in phytochemistry and flower–insect visitor interactions along an Andean elevation gradient

Ecology and Evolution, Volume 13, Issue 8, August 2023., 2023
In this study, we detected patterns of ecological convergence along elevation in floral volatiles as well as cost–benefit ratio in seed versus pollinated seeds. Our results suggest that these evolutionary patterns are the result of biotic and abiotic pressures.
