Different strategies for convective O2 transport in high altitude birds: A graphical analysis

For illustrative purposes, in this article we use “Johansen Plots” as a graphical way of simultaneously visualizing the inter-connected variables that compose convective steps gas transport cascade. These plots are used to reflect on some physiological characteristics seen five species birds, four which sojourn to, or native high altitudes (the barnacle goose, bar-headed Andean speckled teal and ruddy duck). were chosen emphasize diversity responses hypoxia can exist within single family. This likely arose for many possible reasons, including local adaptation hypoxia, differences flight diving abilities, result other phylogenetically-based across waterfowl physiology, behaviour, and/or life style.
