Abstract Climate change poses a significant challenge to all natural systems on Earth. Especially increases in extreme weather events such as heat waves have the potential strongly affect biodiversity, though their effects are poorly understood due lack of empirical data. Therefore, we here explore sensitivity tropical ectotherm, which general believed low warming tolerance, experimentally simulated climate using ecologically realistic diurnal temperature cycles. Increasing mean permanently...
Oxidative stress has been proposed to mediate one of the most important aspects life-history evolution: trade-off between reproduction and self-maintenance. However, empirical studies have cast doubt on generality this intriguing notion. Here, we hypothesize that alters oxidative status only when a self-maintenance occurs. Accordingly, in female Bicyclus anynana butterflies, found affected markers under challenging thermal conditions made longevity emerge. Interestingly, such conditions,...
Abstract Anthropogenic global change, including agricultural intensification and climate poses a substantial challenge to many herbivores due reduced availability of feeding resources. The concomitant food stress is expected detrimentally affect performance, amongst others in dispersal‐related traits. Thus, while dispersal utmost importance escape from deteriorating habitat conditions, such conditions may negatively feedback on the ability do so. Therefore, we here investigate impact larval...
Abstract Dispersal, defined as any movements potentially leading to gene flow, is a major process driving species’ capacity cope with human‐induced environmental modifications. However, the dispersal multi‐causal, which currently hinders predictions regarding resilience global change. We used multifaceted approach disentangle relative importance of suite dispersal‐related factors in butterfly Lycaena tityrus , including condition‐ (morphology and behavior) context‐ (environmental) dependent...
Anthropogenic interference forces species to respond changing environmental conditions. One possible response is dispersal and concomitant range shifts, allowing individuals escape unfavourable conditions or track the shifting climate niche. Range expansions depend on both capacity ability establish populations beyond former range. We here compare well-established core with recently established edge in currently northward expanding butterfly Lycaena tityrus. Edge were characterized by...
1. Individual movement behaviour governs several routine processes, and may scale up to important ecological including dispersal. However, is affected by a wealth of factors, abiotic conditions, flight performance, behavioural traits. Although it has been historically assumed that insect in the first place ruled physiology morphology, researchers have only recently begun understand potentially role 2. This study aims disentangle relative importance thermal conditions during development,...
In this study we investigate small-scale patterns in movements (time until take-off, number of positions vis
