If the population can be shown to be decreasing in size, then the lambda would be positive while the r would be negative.
What happens when the population is decreasing?
When the population is decreasing, the rate would be negative because the population is shrinking. This is why r - which is rate - will be negative.
Lambda on the other hand will be positive to show that the population started from a higher value and is now decreasing.
