Allometric trajectories of body and head morphology in three sympatric Arctic charr (Salvelinus alpinus (L.)) morphs
A study of body and head development in three sympatric reproductively isolated Arctic charr (Salvelinus alpinus (L.)) morphs from a subarctic lake (Skogsfjordvatn, northern Norway) revealed allometric trajectories that resulted in morphological differences. The three morphs were ecologically assigned to a littoral omnivore, a profundal benthivore and a profundal piscivore, and this was confirm...
متن کاملBehaviour, 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 کاملCarotenoid Concentration of Arctic Charr (Salvelinus Alpinus L.) from Spectral Data
The most striking feature of Arctic Charr (Salvelinus alpinus L.) is the red abdomen area during the mating season. This colouration is assumed to be related to the vitality, nutritional status, foraging ability and generally health of the fish – an important knowledge to fisheries and researchers. The colouration should be assessed numerically, and the amount of pigment (carotenoid) causing th...
متن کاملHolarctic phylogeography of Arctic charr (Salvelinus alpinus L.) inferred from mitochondrial DNA sequences.
This study evaluated mitochondrial DNA (mtDNA) sequence variation in a 552-bp fragment of the control region of Arctic charr (Salvelinus alpinus) by analyzing 159 individuals from 83 populations throughout the entire range of the complex. A total of 89 (16.1%) nucleotide positions were polymorphic, and these defined 63 haplotypes. Phylogenetic analyses supported the monophyly of the complex and...
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...
