For almost 40 years, studies of whole-organism performance have formed a cornerstone of
evolutionary physiology. Although its utility as a heuristic guide is beyond question, and we …

Phenotypic flexibility in physiological, morphological and behavioural traits can allow
organisms to cope with environmental challenges. Given recent climate change and the …

Larval nutrition may affect a range of different life history traits as well as responses to
environmental stress in adult insects. Here we test whether raising larvae of fruit flies …

Metabolic rate has been linked to several components of fitness and is both heritable and
repeatable to a certain extent. However, its repeatability can differ among studies, even after …

Bio-conversion of different organic waste streams in Hermetia illucens larval biomass
suitable for animal feed is a promising sustainable solution across different sectors …

Although rove beetles (Paederus spp.) play a beneficial role as biological control agents to
manage crop pests in agro-ecosystems, their high prevalence in human settings has …

Background The amount and quality of nutrients consumed by organisms have a strong
impact on stress resistance, life-history traits and reproduction. The balance between energy …

Laboratory colonies of cotton bollworm larvae, Helicoverpa armigera, kept at 20° C under a
photoperiod of L: D= 10: 14 were fed on five host plants (cotton, corn, kidney bean, tobacco …

Fitness depends not only on resource uptake but also on the allocation of these resources to
various life history functions. This study explores the life-history consequences of larval diet …

Understanding the factors that drive geographic variation in life history is an important
challenge in evolutionary ecology. Here, we analyze what predicts geographic variation in …
