Opponents of biotechnology say they see not so much an opportunity as opportunism by its proponents to exploit the food crisis.
Some, such as the wood pigeon (Columba palumbus), have secondarily adapted to more-open country to exploit the food supplies created by agricultural expansion.
This industry, which dates to the 8th millennium bce, is a conglomeration of cultures that exploited the food resources of lakes, rivers, and surrounding areas from Lake Rudolf in East Africa to the bend of the Niger River in West Africa during a long era of wetter climate and higher lake levels than prevail today.
Employed bees are those who currently exploit the food source.
Employed and onlooker bees then exploits the food sources in sequence until some food sources become exhausted.
Employing a transmission chain design, we show foraging traditions in guppies, Poecilia reticulata, and southern platyfish, Xiphophorus maculatus, in which shoal members continue to exploit the food available in the feeding tube, in spite of changes in the composition of the shoal due to the gradual removal of demonstrators.
Larger colonies are better able to match egg production to expected food intake, and better able to avoid costs associated with producing more brood than can be reared while reducing the risk of under-exploiting the food resources that may be available.
ECI is generally a measure of an insect's capability to exploit the food ingested for growth [ 48].
As the last glacial occurred during 80,000 10,000 years ago, the northward migration of D-M174 is consistent with the proposed notion that modern humans might exploit the food of "Mammoth Steppe" [ 39].
We stress that our approach of studying free-ranging ravens that exploit the food of zoo animals has its constraints and we need to be careful in generalizing our findings to ravens in other ecological conditions.
