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)

open access: yesAgricultural 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. To establish that contact pheromones are involved in mate recognition of C. welensii, we extracted the cuticular hydrocarbons by solid phase microextraction at pre‐reproductive, beginning and ending of the ...

The database of the PREDICTS (Projecting Responses of Ecological Diversity In Changing Terrestrial Systems) project

open access: yesEcology and Evolution, Volume 7, Issue 1, Page 145-188, January 2017., 2017
The collation of biodiversity datasets with broad taxonomic, biogeographic, and spatial extents is necessary to understand historical declines and to project—and hopefully avert—future declines. We describe and make freely available a database of more than 3.2 million biodiversity measurements from 94 countries representing over 47,000 species ...

The PREDICTS database: a global database of how local terrestrial biodiversity responds to human impacts

open access: yesEcology and Evolution, Volume 4, Issue 24, Page 4701-4735, December 2014., 2014
The collation of biodiversity datasets with broad taxonomic and biogeographic extents is necessary to understand historical declines and to project – and hopefully avert – future declines. We describe a newly collated database of more than 1.6 million biodiversity measurements from 78 countries representing over 28,000 species, collated from existing ...

Testing the contribution of vertebrate predators and leaf traits to mainland–island differences in insect herbivory on oaks

open access: yesJournal of Ecology, Volume 113, Issue 1, Page 140-154, January 2025.
The authors explored how insularity influences herbivory in oaks across island–mainland sites. By experimentally excluding vertebrate predators (e.g. birds, bats) and measuring leaf traits (e.g. phenolics, specific leaf area, nutrients), they provide insights into the mechanisms driving island–mainland herbivory patterns.
