Immune function versus antioxidant defense

This file holds data collected in the field on sedentary and migratory common blackbirds (Turdus merula). It gives values of the birds' baseline innate immune function (microbial killing capacity) and oxidative state (total non-enzymatic antioxidant capacity and malondialdehyde level, indicate of oxidative damage to lipids)

data Hegemann et al 2017 FrontZool

All data for the publication "Hegemann A, Pardal S & Matson KD: Indices of immune function used by ecologists are mostly unaffected by repeated freeze-thaw cycles and methodological deviations. Frontiers in Zoology 14:43" divided over 4 different sheet

data Hegemann et al Partial migration

Excel table with 3 sheets. First sheet contains all raw data needed for Post-winter comparisons including all reproductive data, physiological data, morphological data and return rate as well as stable isotope values used for assigning birds as migrants, residents or unknown, respectively. From these table also comparisons between age and sex classes, consistency versus switching of strategies and tarsus length among switchers, obligate residents and obligate migrants can be extracted. Sheet 2 contains all data for the within-individual comparisons (longitudinal data). Sheet 3 contains data regarding the test for assortative mating

Body mass of skylarks per annual cycle stage after 13 h of nightly metabolic measurements.

<p>Experimental birds were injected with LPS; control birds were un-injected.</p

Body mass and mass-specific basal metabolic rate (BMR) of control skylarks throughout the annual cycle.

<p>Body mass measurements were taken in the mornings upon completion of the metabolic measurements. Numbers represent samples sizes.</p

Statistics and coefficients of the linear models of measures of metabolism, body mass and temperature in skylarks.

Effect of LPS injection on a) mass-specific nightly metabolic rate, b) body temperature, c) relative mass loss during the night, d) absolute mass loss during the night, e) glucose concentration and f) ketone concentration of skylarks after 13 hours.

<p>Experimental birds were injected with LPS; control birds were un-injected. Black symbols represent experimental birds (LPS-injected), grey symbols control birds (un-injected). Bars represent the difference between these two groups. Means and standard errors are shown; numbers in bars represent sample sizes per group (control/experimental). The graphs show raw data without correcting for sex effects. There was never a significant treatment* annual cycle stage interaction (all P>0.084).
