... Mathematical model Reptile Shunting If digestion is facilitated by supplying the gut with blood with higher CO 2 levels, our model predicts that this is best mediated by reducing ACR instead of increasing R­–L shunt. Elevating CO 2 levels by increasing R–L shunt would come at the cost of pronounced...

... ( Alben et al., 2002 ; de Langre, 2008 ; Niklas, 1999 ; Speck and Burgert, 2011 ; Steinberg, 2002 ; Theckes et al., 2011 ). Because plant tissues generally have complex material properties, translating their design into manmade materials or mathematical models is not straightforward. Experiments...

.... Here we capitalize on the benthic lifestyle of the upside-down jellyfish ( Cassiopea xamachana ) to explore the fluid dynamics of feeding uncoupled from swimming. A two-dimensional mathematical model is developed to capture the fundamental characteristics of the motion of the unique concave bell shape...

... that boundary layers of air around eggs, and around substrates to which they are attached, offer negligible resistance. Likewise, a mathematical model, parameterized using published and newly obtained morphological data,predicts that air-filled parts of the chorion also do not resist oxygen flux...
