Here, females would be coded as 0 and males as 1. As a result, female survival is just the intercept (beta 0).
The value for beta 1 is the difference in survival between males and females.
If males had of been coded as 0's then male survival would have been the intercept, and beta 1 would have been the difference of female survival from male.
Beta 2 shows the effect of temperature on survival (of the base model - in this case the females). As temperature increases, female survival also increases, so there is a positive relationship between temperature and female survival.
The interaction term (beta 3) looks at whether males and females are affected by temperature in different ways or whether temperature affects them in exactly the same way. If they were both affected in the same way then the male survival line would look like the dotted female survival gradient line (this is just the the solid female survival line moved up to cross at the same intercept point). Here, males are more strongly affected by temperature than females because their slope is steeper. The beta 3 value is therefore the difference between males and females in how they are affected by temperature.
