Genetic basis of variation in morphological and life-history traits of a wild population of pink salmon.
Understanding the genetic basis of phenotypic variation is essential for predicting the direction and rate of phenotypic evolution. We estimated heritabilities and genetic correlations of morphological (fork length, pectoral and pelvic fin ray counts, and gill arch raker counts) and life-history (egg number and individual egg weight) traits of pink salmon (Oncorhynchus gorbuscha) from Likes Cre...
متن کامل: metadiscourse in introduction sections of applied linguistics and physics research articles: exploring variation in frequency and type
abstract in written mode of language, metadiscourse markers are used commonly to help writers in general and academic writers in particular to produce coherent and professional texts. the purpose of the present study was to compare introduction sections of applied linguistics and physics articles regarding their use of interactive and interactional metadiscourse markers based on the model pro...
15 صفحه اولMorphological variation and Taxonomic validation of gill raker characteristics in Caspian marine shad (Clupeidae: Alosa braschnikowi)
We used 50 specimens of Alosa braschnikowi (A. brschnikowi) to study the growth effect on Gill raker morphology. Gill rakers counted as 26-47 which increased in relation to increase in TL (P<0.05). Gill raker lengths and the length:width ratio decreased with a high coefficient of relationships (R2=0.818 and 0.634 subsequently) regarding the increase of TL. The proportion of gill raker length to...
متن کاملGeomagnetic imprinting predicts spatio-temporal variation in homing migration of pink and sockeye salmon.
Animals navigate using a variety of sensory cues, but how each is weighted during different phases of movement (e.g. dispersal, foraging, homing) is controversial. Here, we examine the geomagnetic and olfactory imprinting hypotheses of natal homing with datasets that recorded variation in the migratory routes of sockeye (Oncorhynchus nerka) and pink (Oncorhynchus gorbuscha) salmon returning fro...
متن کاملRates and patterns of microsatellite mutations in pink salmon.
The tendency of microsatellites to be highly polymorphic is a major factor responsible for their popularity as markers for ecological and evolutionary studies. Microsatellite polymorphism is generally attributed to slipstrand mispairing errors, causing the addition or deletion of repeat units during replication (Levinson and Gutman 1987). Valdes, Slatkin, and Freimer (1993) found that human mic...
