Understanding the evolution of insect mating behavior is essential for explaining how early insects adapted to life on land.

Drosophila is one of the most thoroughly studied lab animals -- with the exception of the female reproductive tract. Now a team of biologists has taken the first deep look at the Drosophila uterus and ...

Thermogenesis is present in plants such as 'Macrozamia communis', which raise the temperature of their reproductive organs when in bloom to attract pollinating insects. Thermogenesis is a process by ...

COLUMBUS, Ohio – A lab study in crickets has revealed sex differences in how the insects direct their nutritional resources to increase chances of generating offspring, finding that females prepare ...
