Specialization, Constraints, and Conflicting Interests in Mutualistic Networks
The topology of ecological interaction webs holds important information for theories of coevolution, biodiversity, and ecosystem stability . However, most previous network analyses solely counted theExpand

Extrafloral nectar production of the ant-associated plant, Macaranga tanarius, is an induced, indirect, defensive response elicited by jasmonic acid.
Plant species in at least 66 families produce extrafloral nectar (EFN) on their leaves or shoots and therewith attract predators and parasitoids, such as ants and wasps, which in turn defend themExpand

Diversity, evolutionary specialization and geographic distribution of a mutualistic ant-plant complex: Macaranga and Crematogaster in South East Asia
Abstract The most conspicuous and species-rich ant-plant mutualism in the Malesian region is found in the important pioneer tree genus Macaranga , yet little is known about the identities orExpand

Studies of a South East Asian ant-plant association: protection of Macaranga trees by Crematogaster borneensis
SummaryIn the humid tropics of SE Asia there are some 14 myrmecophytic species of the pioneer tree genus Macaranga (Euphorbiaceae). In Peninsular Malaysia a close association exists between the treesExpand

Thrips pollination of the dioecious ant plant Macaranga hullettii (Euphorbiaceae) in Southeast Asia.
Discussion about thrips (Thysanoptera) as main pollinators has been controversial in the past because thrips do not fit the preconception of an effective pollinator. In this study, we presentExpand

Molecular analysis of phylogenetic relationships among Myrmecophytic macaranga species (Euphorbiaceae).
Many species of the paleotropical pioneer tree genus Macaranga Thou. (Euphorbiaceae) live in association with ants. Various types of mutualistic interactions exist, ranging from the attraction ofExpand

A chloroplast genealogy of myrmecophytic Macaranga species (Euphorbiaceae) in Southeast Asia reveals hybridization, vicariance and long‐distance dispersals
Macaranga (Euphorbiaceae) includes about 280 species with a palaeotropic distribution. The genus not only comprises some of the most prominent pioneer tree species in Southeast Asian lowlandExpand

Studies on the south east Asian ant-plant associationCrematogaster borneensis/Macaranga: Adaptations of the ant partner
SummaryC. borneensis (Myrmicinae) lives in close association with several myrmecophytic species of the South East Asian pioneer tree genusMacaranga (Euphorbiaceae). The ants are adapted to the plantsExpand

Diversity of ant-plant interactions: protective efficacy in Macaranga species with different degrees of ant association
The pioneer tree Macaranga in SE Asia has developed manyfold associations with ants. The genus comprises all stages of interaction with ants, from facultative relationships to obligate myrmecophytes.Expand

Trade-Off Between Chemical and Biotic Antiherbivore Defense in the South East Asian Plant Genus Macaranga
The plant genus Macaranga is known for its manifold mutualistic associations with ants. The plants provide food for the ants and in turn get protection from herbivores. Depending on the strength ofExpand
