What Is The Relationship Between Ants And Acacia Trees?
2021年10月10日 · Pseudomyrmex ferruginea, or the acacia ant, are small stinging ants that live among the swollen thorns of the bullhorn acacia tree. The tree relies on these ants to defend its leaves by attacking hungry herbivores that try to snack on the leaves.
The Mutualistic Relationship Between Ants and Acacias
2019年10月31日 · The acacia trees produce specialized structures to shelter and feed the ant colony, and the ants, in turn, defend the tree against herbivores. In a recent study in Proceedings of the National Academy of Sciences, colleagues of Janzen’s in the biology department uncover a genetic mechanism that programs the plant side of the ant-acacia relationship.
Trees Trap Ants Into Sweet Servitude - National Geographic
2013年11月6日 · In Central America, ants act as bodyguards for acacia trees, defending them from weeds and hungry animals in exchange for room and board, one of the most iconic alliances in nature. (See "Ant...
Timing is everything for the mutualistic relationship between ants …
2019年7月15日 · With a new insight into a long-described mutualistic relationship, plant biologists from the School of Arts and Sciences reveal the genetic factors and evolutionary forces that govern the development of the acacia’s ant-sustaining traits.
Strategies of acacia-ants: to grow or to reproduce?
2011年1月14日 · We will analyze the colony structure of different mutualistic and parasitic acacia ants to see how much each species invests in colony growth (via workers that provide protection) versus reproduction (via sexuals) by counting all the individuals from several previously sampled acacia trees from Mexico.
Of Ants, Elephants and Acacias: A Tale of Ironic Interdependence
2008年1月10日 · Acacia drepanolobium. In the absence of herbivores, the whistling acacia stopped producing little ant houses in hollow thorns—known as domatia—and excreting the sweet nectar that its bodyguard...
Acacia ants: Current Biology - Cell Press
2023年6月5日 · Acacia ants are a group of specialized defensive symbionts that live in association with trees formerly in the genus Acacia (now reclassified as the genus Vachellia) and are members of a broader class of ‘plant ants’ that form mutualistic associations with plants in tropical and sub-tropical regions around the globe. Within ant–acacia ...
The acacia ants revisited: convergent evolution and …
2017年3月15日 · We sampled all 10 species of obligate acacia ants in the P. ferrugineus group ; two other generalist species recently implicated as part of the P. ferrugineus group ; and five other closely related species of Pseudomyrmex.
The Complicated Relationship Between Ants and Whistling Thorn Acacia …
2021年6月18日 · The whistling thorn acacia tree (Vachellia drepanolobium – formerly Acacia drepanolobium) is a dominant plant species in the heavy-clay soils of upland East Africa. These trees combine structural defenses (thorns) with ant mutualisms in a strategy to deter grazing by large herbivores like elephants and giraffes.
