Data and code from: Effects of temperature and browning on the functional response of a freshwater top predator

This dataset contains data and code underlying a study of how temperature
and water browning affect feeding rates and functional responses of a
freshwater top predator, the northern pike (Esox lucius). The archive
includes data from two controlled laboratory experiments quantifying pike
feeding on roach across gradients of temperature, prey density, and water
colour (browning), as well as year-round body temperature records from
free-ranging adult pike equipped with implanted biosensors. Experiment 1
provides replicated functional-response data across three temperatures (5,
9, and 13 °C) and two visual conditions (clear and brown water) at four
prey densities. Experiment 2 quantifies feeding rates at two prey
densities across a browning gradient ranging from completely clear to
extremely brown water. Additional files include predator body mass
measurements and continuous body-temperature time series used to validate
climatic simulations of winter thermal regimes. All raw data, processed
variables, and fully reproducible R code used for statistical analyses,
functional-response fitting, model comparison, and figure generation are
included.
