... Rivulidae Killifish An animal's survival and reproductive success depend on its ability to either operate in variable environments or relocate when conditions become suboptimal. The decision to stay or leave is ultimately based on which option maximizes the animal's fitness ( Nguyen et al., 2013...

... of the Gulf killifish, Fundulus grandis , during closed and intermittent-flow respirometry. Fitting two line segments of Ṁ O 2 versus P O 2 produced high and variable estimates of P crit , as did nonlinear regression using a hyperbolic (Michaelis–Menten) function. Using nonlinear regression fit to an...
