Do atmospheric events explain the arrival of an invasive ladybird (Harmonia axyridis) in the UK?

open access: yesPLoS ONE, 2020
Species introduced outside their natural range threaten global biodiversity and despite greater awareness of invasive species risks at ports and airports, control measures in place only concern anthropogenic routes of dispersal.

Patterns of contribution to citizen science biodiversity projects increase understanding of volunteers’ recording behaviour [PDF]

open access: yes, 2016
The often opportunistic nature of biological recording via citizen science leads to taxonomic, spatial and temporal biases which add uncertainty to biodiversity estimates.

Reliable ABC model choice via random forests

open access: yes, 2015
Approximate Bayesian computation (ABC) methods provide an elaborate approach to Bayesian inference on complex models, including model choice. Both theoretical arguments and simulation experiments indicate, however, that model posterior probabilities may ...

Insectum non grata: the harlequin ladybird, Harmoniaaxyridis (Pallas, 1773) (Coleoptera, Coccinellidae) in Turkey

open access: yesTURKISH JOURNAL OF ZOOLOGY, 2021
The Harlequin Ladybird, Harmonia axyridis (Pallas, 1773), is native to Eastern Asia but it has been introduced to many countries in Africa, America, and Eurasia. In Turkey, H. axyridis is one of the most fast-spreading invasive alien species. Since the collection of the first specimens in 2010, H. axyridis spread almost all over the country.

Harmonia axyridis (Coleoptera: Coccinellidae): Smelling the rat in native ladybird declines

open access: yesEuropean Journal of Entomology, 2017
In the last two decades a huge amount of research has focused on the invasive harlequin ladybird, Harmonia axyridis, particularly on potential or actual deleterious effects that have arisen after it has colonised new regions.

First finding of the parasitic fungus Hesperomyces virescens (Laboulbeniales) on native and invasive ladybirds (Coleoptera, Coccinellidae) in South Africa

open access: yesParasite, 2016
Hesperomyces virescens is a fungal ectoparasite (Laboulbeniales) that infects adult ladybirds. Research has recently focused on this parasite due to the discovery of its prevalence on the globally invasive harlequin ladybird Harmonia axyridis and for its

Top-down control by Harmonia axyridis mitigates the impact of elevated atmospheric CO2 on a plant-aphid interaction [PDF]

open access: yes, 2014
1. The present study investigated the impact of elevated atmospheric CO2 (390 or 650 μmol/mol) on raspberry genotypes varying in resistance to the large raspberry aphid Amphorophora idaei and any subsequent impact on the coccinellid predator Harmonia ...

The Rare Five-Spot Ladybird Coccinella quinquepunctata (Coleoptera: Coccinellidae) Surviving in an Unstable Habitat

open access: yesFrontiers in Conservation Science, 2022
Coccinella quinquepunctata (the five-spot ladybird), was considered extinct in the UK until 1987. Since this time the species is abundant, however, only in very specific habitat in Wales and Scotland.

Elevated atmospheric CO2 impairs aphid escape responses to predators and conspecific alarm signals [PDF]

open access: yes, 2014
Research into the impact of atmospheric change on predator–prey interactions has mainly focused on density dependent responses and trophic linkages. As yet, the chemical ecology underpinning predator–prey interactions has received little attention in ...
