摘要: Habitat heterogeneity that occurs within an individual's lifetime may favour the evolution of reversible plasticity. Colour reversibility has many different functions in animals, such as thermoregulation, crypsis through background matching and social interactions. However, mechanisms underlying colour changes are yet to be thoroughly investigated. This study aims determine environmental hormonal factors morphological Thomisus onustus crab spiders biochemical metabolites produced during these changes. We quantified dynamics over time: were kept yellow white containers under natural light conditions their was measured 15 days using a spectrophotometer. also characterised chemical changing HPLC. Hormonal control change investigated by injecting 20-hydroxyecdysone (20E) into spiders. found colouration major factor responsible for spiders: individuals presented with backgrounds changed colours, respectively. An ommochrome precursor, 3-OH-kynurenine, main pigment colour. Spiders injected 20E displayed similar rate towards exposed sunlight. demonstrates novel manipulations capable inducing change.
