Relationships between locomotor activity, oxidative damage and life span in males and females of the linden bug, Pyrrhocoris apterus (Heteroptera: Pyrrhocoridae)

open access: yesEuropean Journal of Entomology, 2013
In this study we addressed a question of whether experimental manipulations that increase life span also reduce physical activity and molecular oxidative damage.

Diel changes in adipokinetic response and walking activity of Pyrrhocoris apterus (Heteroptera) in relation to physiological status and wing dimorphism

open access: yesEuropean Journal of Entomology, 2001
Three experimental groups of adult females of Pyrrhocoris apterus (reproductive brachypterous, diapausing brachypterous, and macropterous with non-diapause type of reproductive arrest) were analysed for their dose dependency of adipokinetic response ...

Locomotion in Response to Shifting Climate Zones: Not So Fast [PDF]

open access: yes, 2010
Although a species’ locomotor capacity is suggestive of its ability to escape global climate change, such a suggestion is not necessarily straightforward. Species vary substantially in locomotor capacity, both ontogenetically and within/among populations,
