In the threespine stickleback Gasterosteus aculeatus model system,
phenotypes are often classified into three morphs according to lateral
plate number. Morph identity has been shown to be largely genetically
determined, but substantial within-morph variation in plate number exists.
In this study, we test whether plate number has a plastic component in
response to salinity in the low-plated morph using a split-clutch
experiment where families were split in two, one half raised in water at 0
and the other at 30 ppt salt. We find a small salinity-induced plastic
effect on plate number in an unexpected direction, opposite to what we
predicted: Fish raised in freshwater on average have slightly more plates
than fish raised in saltwater. Our results confirm that heritability of
plate number is high. Additionally, we find that variance in plate number
at the family level can be predicted from other family level traits, which
might indicate that epistatic interactions play a role in creating the
observed pattern of lateral plate number variation.
Hansson et al. Plates count dataThis file includes the raw data from the
study 'Lateral plate number in low-plated threespine stickleback: a
study of plasticity and heritability' by Truls H. Hansson, Barbara
Fischer, Anna B. Mazzarella, Kjetil L. Voje and Leif Asbjørn Vøllestad
published 2016 in Ecology and Evolution. For 739 threespine stickleback
offspring individuals, which were either raised in saltwater or
freshwater, lateral plates were counted. For each of these individuals (in
rows), the file has the following information (in columns): FishID
(individual fish ID), FamilyID (ID for the 16 Crosses), Treatment (F for
freshwater, S for saltwater), Plates left (no of lateral plates on the
left side of the fish), Plates right (no of lateral plates on right side
of the fish), Density (no of individuals per tank, in which they were
raised) and Size (body length, in mm).Hansson_Platescountdata.csv
