Anticipating where are unknown aquatic insects in Europe to improve biodiversity conservation

Diversity and Distributions, Volume 29, Issue 8, Page 1021-1034, August 2023., 2023
Abstract Aim Understanding biodiversity patterns is crucial for prioritizing future conservation efforts and reducing the current rates of biodiversity loss. However, a large proportion of species remain undescribed (i.e. unknown biodiversity), hindering our ability to conduct this task.

Fast species diversification among dragonflies (Anisoptera: Odonata: Insecta) inhabiting lentic environments regardless of wing pigmentation

Ecological Entomology, Volume 47, Issue 3, Page 314-322, June 2022., 2022
Use of novel state‐dependent net diversification methodologies to investigate wing pigmentation (pigmented/non‐pigmented) and aquatic habitat (lotic/lentic) impact on species diversification in dragonflies (Odonata: Anisoptera). Wing pigmentation and habitat influence species diversification.

Geographical variation of prementum size in Iberian Cordulegaster boltonii (Odonata: Cordulegastridae) populations

International Journal of Odonatology, 2022
Within wide geographical areas, Odonata populations can show biometric differences as a consequence of both biotic (e.g., predation, competition) and abiotic factors (mainly temperature). These differences can occur in the larval stage, although reliable characters are needed to detect differences. We analyzed whether Cordulegaster boltonii larvae from
