Behaviour, physiology and carotenoid pigmentation in Arctic charr Salvelinus alpinus.
The behaviour during an exploration task and the response to a confinement stress of Arctic charr Salvelinus alpinus were evaluated. Behaviour of individuals during 90 min of exploration was classified into high and low activity. High-activity individuals had higher plasma cortisol levels following stress compared to low-activity individuals. This indicates that high- and low-activity individua...
متن کاملThe developmental transcriptome of contrasting Arctic charr ( Salvelinus alpinus) morphs
Species and populations with parallel evolution of specific traits can help illuminate how predictable adaptations and divergence are at the molecular and developmental level. Following the last glacial period, dwarfism and specialized bottom feeding morphology evolved rapidly in several landlocked Arctic charr Salvelinus alpinus populations in Iceland. To study the genetic divergence between...
متن کاملExperimental evidence for paternal effects on offspring growth rate in Arctic charr (Salvelinus alpinus).
Sexual selection theory predicts that females should choose males that signal viability and quality. However, few studies have found fitness benefits among females mating with highly ornamented males. Here, we use Arctic charr (Salvelinus alpinus), a teleost fish with no parental care, to investigate whether females could gain fitness benefits by mating with highly ornamented and large-sized ma...
متن کاملRapid evolution of muscle fibre number in post-glacial populations of Arctic charr Salvelinus alpinus.
Thingvallavatn, the largest and one of the oldest lakes in Iceland, contains four morphs of Arctic charr Salvelinus alpinus. Dwarf benthic (DB), large benthic (LB), planktivorous (PL) and piscivorous (PI) morphs can be distinguished and differ markedly in head morphology, colouration and maximum fork length (FL(max)), reflecting their different resource specialisations within the lake. The four...
متن کاملThe effect of anesthetics on carotenoid pigmentation and behavior in Arctic charr (Salvelinus alpinus)
Status of individual animals is often shown in pigmentation. For instance, stress responsiveness is associated with melanin-based pigmentation in vertebrates in general. This pattern is evident in Atlantic salmon (Salmo salar) and rainbow trout (Onchorhynchus mykiss) with melanin-based spots indicating stress coping style. Arctic charr (Salvelinus alpinus) differ from other salmonids in pigment...
