  Individual-level Data to Accompany “Respiratory Plasticity Induced by Chronic Hyperoxia in Juvenile and Adult Rats”

  Ryan Bavis, Matthew D. Danielson, Gemma Dufour, Julia Hanus, Ashley E. Pratt, and Kristina E. Tobin

  Sprague Dawley rats were exposed to chronic hyperoxia (60% O 2 ) as juveniles or as adults. Ventilation (whole-body plethysmography) and metabolic rate (respirometry) were then measured in normoxia (21% O 2 , balance N 2 ) and during acute hypoxic or hypercapnic challenges (15 – 20 minutes in 12% O 2 or 7% CO 2 , respectively) immediately following chronic hyperoxia or after a period of recovery in room air. The linked data files contain the individual-level ventilation and metabolism data. The full methods and summary data are available in the peer-reviewed article:

  Individual-level Data to Accompany “Recovery of Ventilatory and Metabolic Responses to Hypoxia in Neonatal Rats After Chronic Hypoxia”

  Ryan W. Bavis, Darya I. Lee, Annie C. Kinnally, and Payton E. Buxton

  Rat pups were exposed to 3 days of chronic hypoxia (12% O₂) beginning shortly after birth. Ventilation (head-body plethysmography) and metabolic CO₂ production (respirometry) were then measured in normoxia (21% O₂, balance N₂) and during an acute hypoxic challenge (15b minutes in 12% O₂, balance N₂) immediately following chronic hypoxia and after 1, 4-5, and 7 d in room air; different individuals were studied at each age. The linked data files contain the individual-level ventilation and CO₂ production data. The full methods and summary data are available in the peer-reviewed article:

  Dichotomous Key to Pea Aphid (Acyrthosiphon pisum) Apterous Parthenogenic Instars

  Bates College Department of Biology, Daisy Diamond, and Daniel Levitis

  We provide a dichotomous key, with photographs and illustrations, for distinguishing between instars of the pea aphid (Acyrthosiphon pisum) in the developmental pathway leading to the apterous parthenogenetic adult. Lengths of body, antenna and cauda are provided for a sample of each instar.
