Correction for Perry et al., Rapid behavioral maturation accelerates failure of stressed honey bee colonies

ECOLOGY Correction for “Rapid behavioral maturation accelerates failure of stressed honey bee colonies,” by Clint J. Perry, Eirik Søvik, Mary R. Myerscough, and Andrew B. Barron, which appeared in issue 11, March 17, 2015, of Proc Natl Acad Sci USA (112:3427–3432; first published February 9, 2015; 10.1073/pnas.1422089112).

The authors note that on page 3431, right column, third full paragraph, the set of equations beginning on line 3 appeared incorrectly. The corrected equation appears below.

$$N\left(a\right)=\{\begin{array}{cc}-0.02{\left(a-10\right)}^2+3.5& \text{for}\hspace{0.17em}a\le 10\\ -0.015{\left(a-10\right)}^2+3.5& \text{for}\hspace{0.17em}a>10\end{array}$$

$$T\left(a\right)=\{\begin{array}{ll}0.06\left(a-5\right)+0.5\hfill & \text{for}\hspace{0.17em}a\le \frac{40}{3}\hfill \\ 1\hfill & \text{for}\hspace{0.17em}a>\frac{40}{3}\hfill \end{array}$$

$$M\left(a\right)=\frac{{\left(a-a_0\right)}^4+3}{\left(4.94+0.08a\right){\left(a-a_0\right)}^4}$$
