Paleopteran molecular clock: Time drift and recent acceleration. [PDF]
Ecol EvolConstant evolution rates, which form the foundation of the strict molecular clock model, do not apply in the case of Paleoptera, highlighting a notable bias in the molecular clock hypothesis. The current biodiversity may be the outcome of a relatively recent, exponential increase in base substitution rates.

A straightforward protocol to sample morphological traits of dragonflies and damselflies in the field. [PDF]
Ecol EvolAbstract Scarcity of morphological data limits the potential of functional ecology approaches, which rely on traits to elucidate ecological processes. Dragonflies and damselflies (Odonata) are a frequently used ecological model for which, however, only limited morphological data is available.

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.

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.

The impact of climate-induced distributional changes on the validity of biological water quality metrics [PDF]
, 2010 We present data on the distributional changes within an order of macroinvertebrates used in biological water quality monitoring. The British Odonata (dragonflies and damselflies) have been shown to be expanding their range northwards and this could ...
