The Benefits of Myrmecochory: A Matter of Stature

Biotropica, 2015
AbstractMyrmecochory, or seed dispersal by ants, occurs widely in angiosperms, and particularly in temperate forest herbs in the northern Hemisphere and sclerophyll shrubs in Mediterranean‐climate landscapes. The lipid‐rich elaiosome on the seed provides nutrition to the ants; however, how the plant benefits from myrmecochory remains unclear.

Myrmecochory in Lepidosperma (Cyperaceae): perianth members provide a lipid-rich reward for ants

Australian Journal of Botany, 2021
The diaspores of Lepidosperma Labill. (Cyperaceae) have thickened perianth members persistent at the base of the fruit, which are generally assumed to form a unique type of elaiosome but this assumption has not been tested rigorously. We tested whether the perianth provides a lipid-rich food reward and improves diaspore removal by ants in three species

Ant behaviour and seed morphology: a missing link of myrmecochory

Oecologia, 2005
Seed dispersal by ants (myrmecochory) is mediated by the presence of a lipid-rich appendage (elaiosome) on the seed that induces a variety of ants to collect the diaspores. When seeds mature or fall onto the ground, these ant species transport them to their nest.

Myrmecochory in some plants (F. chenopodiaceae) of the Australian arid zone

Oecologia, 1981
Several common plants (Chenopodiaceae) of the Australian arid zone produce diaspores that bear small and inconspicuous food bodies and are adapted for dispersal by ants. For these species, myrmecochory probably represents an adaptation for highly directional dispersal of diaspores to favorable microsites where nutrients are concentrated and possibly ...

Dispersal distance as a benefit of myrmecochory

Oecologia, 1988
Nutrient-enrichment and predator avoidance are generally considered the major benefits of myrmecochory, but this is apparently not so in Australia where some of the greatest known concentrations of myrmecochorus plants occur. Here I demonstrate that distance dispersal is a potential benefit of myrmecochory in the Australian environment.

Myrmecochory In Cape Fynbos

1991
Abstract In 1975, Berg reported the widespread occurrence of myrmecochory in Australian heathlands. At the time, there was considerable interest in the hypothesis of convergent evolution among the mediterranean climate regions of the world (Cody and Mooney, 1978).

The effects of urbanization on ant communities and myrmecochory in Manitoba, Canada

Urban Ecosystems, 2006
With the increase in urbanization globally, there is an increased need to understand the ecology of forest fragments in urban and urbanizing landscapes. Although urban forests are known to be relatively lacking in plants whose seeds are dispersed by ants, little is known about the effects of urbanization on the community composition and behaviour of ...

Methods for studying myrmecochory

2003
The previous chapters demonstrated some of the plant adaptations to myrmecochory, the principal stages of diaspore dispersal by ants, and the influence of various factors on the effectiveness of dispersal in different stages as well as advantages obtained by plants from this method of dispersal.

Myrmecochory in Australia's seasonal tropics: Effects of disturbance on distance dispersal

Australian Journal of Ecology, 1998
Abstract Successful ecosystem restoration requires the re‐establishment of fundamental ecological processes, many of which involve plant‐animal interactions. Myrmecochory (seed dispersal by ants) is a particularly important plant‐animal mutualism in Australia, but little is known about its response to either disturbance or restoration following ...
