WebMyrmecochorous plant cover was positively related to gastropod abundance but was negatively related to ant abundance. Gastropods were responsible for most seed removal and elaiosome damage, whereas insects (and rodents) played minor roles. These gastropod effects on seeds were independent of region or forest management. WebThe exceptionally high incidence of myrmecochory (ant-dispersed species) in Cape fynbos and similarly fire-prone vegetation on nutrient-poor soils in Australia has aroused much interest. An ecological advantage of myrmecochory on both continents is the removal of seeds to sites safe from seed predation. By failing to address evolutionary ...
