Patterns of variation in wing venation of Iberian Cordulegaster boltonii (Donovan, 1807) (Odonata: Cordulegastridae)

open access: yesInternational Journal of Odonatology, 2023
Some structural characters, such as wing venation, have been used in odonates to differentiate taxa. In Cordulegaster boltonii, a species widely distributed throughout the western Palaearctic, the main characteristics of its wing venation have not been ...

Fossil gaps inferred from phylogenies alter the apparent nature of diversification in dragonflies and their relatives. [PDF]

open access: yesBMC Evol Biol, 2011
Background The fossil record has suggested that clade growth may differ in marine and terrestrial taxa, supporting equilibrial models in the former and expansionist models in the latter. However, incomplete sampling may bias findings based on fossil data

Geography, taxonomy, and ecological guild: Factors impacting freshwater macroinvertebrate gut microbiomes. [PDF]

open access: yesEcol 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]

open access: yesPest 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.
