Declining bumblebee populations are at greater risk of inbreeding, which can trigger a downward spiral of further decline. Researchers have provided the first proof that inbreeding reduces colony ...

Mongrel lot The mysterious and widespread collapse of bee colonies in many parts of the world is not due to a lack of genetic diversity, a new study has found. The study by Brock Harpur, of York ...

One of the last remaining colonies of a rare kiwi species has been ravaged by severe inbreeding, researchers say. A Marlborough colony of the little spotted kiwi – smallest and second rarest kiwi ...

Declining bumblebee populations are at greater risk of inbreeding, which can trigger a downward spiral of further decline. Researchers writing in the open access journal BMC Evolutionary Biology have ...

Recombination, or crossing-over, occurs when sperm and egg cells are formed and segments of each chromosome pair are interchanged. This process plays an crucial role in the maintenance of genetic ...

Haplodiploidy is one of the most widespread mechanisms of sex determination in animals. In many Hymenoptera, including all hitherto investigated social species, diploid individuals, which are ...

DECLINING bumblebee populations could be caught in a downward spiral, according to Stirling University scientists. DECLINING bumblebee populations could be caught in a downward spiral, according to ...

Termite colonies are families - millions of individual workers all descended from one king and one queen. But the colony itself tends to outlast this initial royal couple. When they die, new kings and ...
