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 the convective steps of the gas transport cascade. These plots are used to reflect on some of the physiological characteristics seen in five species of birds, four of which sojourn to, or are native to, high altitudes (the barnacle goose, bar-headed goose, Andean goose, speckled teal and …
