An experimental, behavioral, and chemical analysis of food limitations in mutualistic Crematogaster ant symbionts inhabiting Macaranga host plants
2023
Obligate mutualistic plant-ants are often constrained by their plant partner's capacity to provide resources. However, despite this limitation, some ant partners actively reject potential prey items and instead drop them from the plant rather than consuming them, leaving the ants entirely reliant on host plant-provided food, including that provided indirectly by the symbiotic scale insects that ants tend inside the plants. This dependency potentially increases the efficiency of these ants in defending their host. We hypothesize that if this ant behavior was beneficial to the symbiosis, prey rejection by ants would be observed across multiple plant host species. We also hypothesize that plan…
Observations on ant-plant interactions in Pachycentria and other genera of the Dissochaeteae (Melastomataceae) in Sabah and Sarawak
1998
Summary In Sabah and Sarawak (Malaysia) ant-plant interactions of Dissochaeteae were studied in the field. Whereas some species of Dissochaeteae show only loose and fortuitous interactions with ants as the result of the provision of pearl bodies and nesting places which are used by ants facultatively, Pachycentria constricta and P. glauca show a complex relationship with ants mediated by other ant plants. Both species provide pearl bodies and potential nesting space or shelter for ants in dried out and hollow root swellings. The main characteristic which differentiates them from all other Melastomataceae interacting with ants are their particular seeds which are attractive to ants and carri…
Profil Tempat Tumbuh Sarang Semut (Myrmecodia spp.) Di Distrik Manokwari Selatan Papua Barat
2019
Papua has a very high diversity of flora species, one of which is a type of Sarang Semut. Different growing conditions will affect the level of diversity of plants. For that information about the place to grow Ant Plant is needed as basic information for the development of the cultivation of Ant plants. The method used is descriptive method with field observation technique. The results showed that the type of ant nest plant found in South Manokwari was a type of Myrmecodia pendans and Myrmecodia cf. schlechteri. Both of these species do not grow evenly in all study locations even at the same height, this plant has a characteristic growing place: it grows on host trees that are not slippery,…
