Rearranging nest boxes keeps more blue orchard bees around

Orchard growers looking for alternatives to honey bees for managed pollination services have new reason to be optimistic about the potential of one honey bee cousin, the blue orchard bee. A recent research experiment has shown blue orchard bees can be a sustainable option in tart cherry orchards, and a simple change to the distribution of the bees’ nesting boxes makes the bees more likely to remain in the orchard to nest. …

Because they don’t have an X or Y chromosome, baby sea turtles’ sex is defined during development by the incubation environment. Warmer sand temperatures produce more females and cooler sand temperatures produce more males. A crucial step in the conservation of these animals is estimating hatchling sex ratios, which remains imprecise because of their anatomical makeup. …
