Heynen M, Hellström G, Magnhagen C, Borcherding J. Does morphological variation between young‐of‐the‐year perch from two Swedish lakes depend on genetic differences?
Ecology of Freshwater Fish 2010: 19: 163–169. © 2009 John Wiley & Sons A/SAbstract –Different local environmental conditions have often been found to generate phenotypic diversity. In the present study we examined morphological differences between young‐of‐the‐year perch from two lake populations with differences in size‐specific predation risk. A common garden setup was used to examine the genetic and environmental components of the morphological variation. We found differences in head and jaw length and slight differences in body depth between the wild young‐of‐the‐year perch from Lake Ängersjön and Lake Fisksjön. The differences found between the wild fish from the two lakes were not maintained under common garden rearing. The observed morphological divergence between the wild young‐of‐the‐year perch from Lake Ängersjön and Lake Fisksjön seems to stem mainly from a plastic response to different environmental conditions in the two lakes. It is clear that the morphological traits are not influenced by direct reaction to the size‐specific risk of cannibalism, but probably stem from a combination of different environment characteristics, including resource and habitat use, and the density of other piscivores, such as pike.
