The Importance of Effective Population Size in Conservation and Biodiversity Monitoring

open access: yesEvolutionary Applications, Volume 19, Issue 1, January 2026.
ABSTRACT Effective population size (Ne) is a key concept in biology and conservation. Stripped to its bare essentials, it reflects how much genetic drift a population experiences, expressed as a number of individuals of an ideal theoretical population. Superficially, Ne seems like a fairly simple concept, but the more layers of the onion you peel, the ...

Integrating eDNA and community science to monitor urban Odonata diversity

open access: yesInsect Conservation and Diversity, Volume 19, Issue 1, Page 84-92, January 2026.
Environmental DNA captured rare and underrepresented taxa often missed by community science observations. Community science revealed adult‐stage observations across a broader temporal window. Integrating both methods improved detection across life stages, seasons, and species prevalence.

Subtle design changes control the difference in colour reflection from the dorsal and ventral wing-membrane surfaces of the damselfly Matronoides cyaneipennis. [PDF]

open access: yes, 2016
The hind wings of males of the damselfly Matronoides cyaneipennis exhibit iridescence that is blue dorsally and green ventrally. These structures are used semiotically in agonistic and courtship display.

Plant structural complexity and mechanical defenses mediate predator-prey interactions in an odonate-bird system. [PDF]

open access: yes, 2017
Habitat-forming species provide refuges for a variety of associating species; these refuges may mediate interactions between species differently depending on the functional traits of the habitat-forming species.

Quantitative Metabarcoding Reveals the Effects of Ecological Factors and Invasive Species on Functional Diversity of Freshwater Insects

open access: yesMolecular Ecology, Volume 35, Issue 1, January 2026.
ABSTRACT Aquatic insects are the most biodiverse freshwater animals. DNA metabarcoding data are increasingly used to assess variation in insect communities, but they are rarely integrated with information on the abundance or biomass of different taxa that can provide key insights into their functional responses.

Finding Isolated Aquatic Habitat: Can Beggars Be Choosers?

open access: yesDiversity
In a two-year field study across 58 isolated wetlands in Texas (USA), we examined whether odonate (Insecta: Odonata) assemblages were structured by local environmental filters or instead simply reflected the use of any available water in this semi-arid ...
