Occurrence and Population Density of the Endemic Species Cordulegaster buchholzi (Anisoptera: Cordulegastridae) on the Cyclades Islands in Greece [PDF]
Insects, 2023 Our research was focused on determining the geomorphological characteristics of streams, characteristics of sediment in streams, habitat, emergence sites and flight period. Larvae were recorded in 19 streams (altitude of 35–680 m a.s.l.), with an average

Geography, taxonomy, and ecological guild: Factors impacting freshwater macroinvertebrate gut microbiomes. [PDF]
Ecol Evol, 2022 Model predictions for mean Bray–Curtis distances for stream locations, macroinvertebrate family, genus, and functional feeding group are assessed. The densities show the posterior distributions of Bray–Curtis distances for each level of stream, family, genus, and functional feeding group. The dot and error bars under each density show the median and 95%

Could species-focused suppression of Aedes aegypti, the yellow fever mosquito, and Aedes albopictus, the tiger mosquito, affect interacting predators? An evidence synthesis from the literature. [PDF]
Pest Manag Sci, 2022 The risks of Aedes aegypti and Aedes albopictus nuisance and vector‐borne diseases are rising and their ranges are expanding. The studies identified by this extensive review come together to suggest little potential risk of adverse impact of suppressing or eliminating invasive Aedes spp. on their predators and food webs.

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.
