WebInbreeding polygyny is not unique to Scolytinae; regular brother/sister mating is found in a wide range of organisms, ranging from eyelash mites to naked mole rats, but it has evolved especially often in bark beetles. Extreme inbreeding has evolved eight times in Scolytinae, and is represented in nine different tribes (Table 3.3).About 27% of all described … WebBiodiversity is essential for the processes that support all life on Earth, including humans. Without a wide range of animals, plants and microorganisms, we cannot have the healthy ecosystems that we rely on to provide us with the air we breathe and the food we eat. And people also value nature of itself.
