The fitness consequences of bearing domatia and having the right ant partner: experiments with protective and non-protective ants in a semi-myrmecophyte. We studied the reaction to tethered earthworms of the three most common ant species found sharing domatia with earthworms. Each plant was then classified into five classes of domatia number. This does not, however, explain why smallbodied ant species do not become main partners of myrmecophytes offering large domatia. Myrmecophytic plants in which individuals produce hollow cavities later in ontogeny are critical to study the evolution of domatia. Plant harvesting was performed during rainy periods, when most workers are normally inside the domatia. In principle, plants control the production of domatia to be used by ant colonies as nesting space. This will tend to mitigate against oversized ants occupying smaller domatia. Additionally, it is possible that small-bodied ant species are inefficient in defending large domatia from invaders. Interspecific differences in domatium volume were characterized by measurements of five domatia per plant species (one randomly selected domatium per plant). Ants that live in the domatia of myrmecophytes have privileged access to the food resources provided by the scale insects. Since the specific weight of the clay is 1.23 + 0.004 g ml-1, the domatia volume could be estimated. For most myrmecophytes, domatia number was used as the estimate of nesting space availability. Juveniles mature inside the domatia during the dry season, and leave them to crawl on the tree leaves during the monsoon probably to mate. Origin of caulinary ant-domatia and timing of their onset in plant ontogeny: evolution of a key trait in horizontally transmitted ant-plant symbioses. Whenever an ant does not find the herbivore, but only the damaged area (as observed here), it immediately goes into the domatia to recruit other workers. |
