Data from: Metabolic traits of westslope cutthroat, introduced rainbow trout and their hybrids in an ecotonal hybrid zone along an elevation gradient

Metabolic traits were measured and regressed against the genetic makeup of individuals and elevation. Rainbow trout had higher oxygen consumption rates (OCR), higher white muscle lactate dehydrogenase (LDH) and citrate synthase (CS) activity, and higher plasma acetylcholinesterase (AchE) than cutthroat trout. Hybrids had intermediate OCR and AchE, but LDH activity as high as rainbow trout.

While hybrid zones are usually modeled as a balance between cross species mating and selection against hybrids, ecotonal hybrid zones, where hybrids proliferate in intermediate habitats and have traits that appear well suited to ecotonal conditions, have been proposed for some plants and animals, and may have important implications for resource management and conservation.

Usage notes

Rasmussen et al data file The data set contains a number of measurements of metabolic traits measured on field caught fish (oxygen consumption rate, white muscle LDH and CS, and plasma acetylcholinesterase, together with the genotypes (pure rainbow trout, pure cutthroat trout or hybrid) body size data and the elevation of the site at which each was captured. These were the data used to generate the models presented in the paper.
