This dataset is used for the analyses and results for the submitted manuscript, 'Parental diet alters thermal reaction norms of offspring development'. Content of the dataset includes data for egg and hatchling brown anole lizards (Anolis sagrei), collected from a laboratory breeding colony during the summer of 2024 at Auburn University.
Dataset: Captivity negatively affects production of red carotenoid pigments in Cardinalis cardinalis (Northern Cardinals)https://aurora.auburn.edu/handle/11200/507622026-02-18T19:10:07ZDataset: Captivity negatively affects production of red carotenoid pigments in Cardinalis cardinalis (Northern Cardinals)
Carotenoid-based coloration is a well-documented example of a condition-dependent trait, but much of the evidence supporting condition dependence of red carotenoid coloration comes from species that color their feathers primarily with 3-hydroxyechinenone, a red carotenoid produced from yellow dietary carotenoids via an unknown pathway. The condition dependence of red plumage in species that use the more common CYP2J19 and BDH1L enzymes to modify dietary yellow carotenoids into red ketocarotenoids is less well studied. We tested the hypothesis that captivity would negatively affect production of red pigments by male Cardinalis cardinalis (Northern Cardinals), a songbird with extensive red coloration produced via the CYP2J19/BDH1L pathway. We confined a group of wild-caught male cardinals in cages during molt, using captivity as a physiological challenge, and compared them to free-living cardinals. We provided captive birds with abundant zeaxanthin and lutein, the dietary yellow pigments that cardinals enzymatically convert into the red ketocarotenoids astaxanthin and alpha-doradexanthin, to ensure that insufficient carotenoid access would not limit production of red pigments. During molt, we measured concentrations of carotenoid pigments in the plasma and growing feather follicles of both captive and free-living cardinals. Compared to free-living cardinals, captive birds had significantly lower relative concentrations of red carotenoids in both follicles and plasma. The observation that, compared to free-living cardinals, captive male cardinals showed reduced production of red carotenoids with lower quantities in feather follicles supports the hypothesis that red coloration produced via the CYP2J19/BDH1L pathway is a condition-dependent trait.
An Fe(II) Complex Detects Hydrogen Peroxide with 1H and 19F Magnetic Resonance Imaging Responseshttps://aurora.auburn.edu/handle/11200/507542026-01-15T20:01:06ZAn Fe(II) Complex Detects Hydrogen Peroxide with 1H and 19F Magnetic Resonance Imaging Responses
We report the fluorinated quinol-containing ligand, 1,8-bis(2,5-dihydroxy-4-fluorobenzyl)-1,4,8,11-tetraazacyclotetradecane (F2H4qp4), and its highly water- and air-stable Fe(II) complex. Upon oxidation by H2O2, the 19F MRI signal of the complex decays while its 1H MRI contrast increases; these spectroscopic responses enable the complex to ratiometrically detect H2O2.
