Ants sow the seeds of global diversification in flowering plants. [PDF]

PLoS ONE, 2009
BACKGROUND:The extraordinary diversification of angiosperm plants in the Cretaceous and Tertiary periods has produced an estimated 250,000-300,000 living angiosperm species and has fundamentally altered terrestrial ecosystems.

Patterns of Functional Diversity, Species Diversity, and Endemicity Driven by Elevation and Topographic Complexity in a Mediterranean Mountain Refuge. [PDF]

Ecol Evol
Within the scope of our study, we modeled and mapped the relationships between functional diversity (Rao's Q), alpha species diversity, and endemism with topographic and climatic factors in a mountainous refugial area encompassing all Mediterranean vegetation strata.

A La Carte Seed Harvesting: <i>Messor barbarus</i> Ants Select Durum Wheat Genotypes. [PDF]

Ecol Evol
Our study shows that the harvester ant Messor barbarus exhibits genotype‐specific preferences for durum wheat, linked to a major QTL on chromosome 2A. Ant predation is also influenced by spike size, suggesting ant‐mediated selective pressure on crop traits.

Reduced dispersal at nonexpanding range margins: A matter of disperser identity

Ecology and Evolution, 2020
The evolution of dispersal at range margins received much attention recently, especially in the context of dynamic range shifts, such as those following climate change.

Seed Elaiosome Mediates Dispersal by Ants and Impacts Germination in Ricinus communis

Frontiers in Ecology and Evolution, 2019
Myrmecochory is the ant-mediated secondary dispersal of seeds that depends on the presence of a lipid-rich seed appendage known as “elaiosome.” Attractive cues of elaiosomes that drive such an interaction and benefits to the plant are not clearly ...

Ants disperse seeds farther in habitat patches with corridors

Ecosphere, 2022
Habitat fragmentation impacts ecosystems worldwide through habitat loss, reduced connectivity, and edge effects. Yet, these landscape factors are often confounded, leaving much to be investigated about their relative effects, especially on species ...

Incorporating redispersal microsites into myrmecochory in eastern North American forests [PDF]

Ecosphere, 2016
AbstractStudies addressing the benefits of “directed dispersal” in ant seed dispersal systems have highlighted the beneficial soil properties of the nests of ants that disperse their seeds. No studies, however, have explored the properties of soils nearby exemplary seed‐dispersing ant nests, where recent work indicates that seeds are quickly ...

Ant species that remove diaspores alone are more efficient removers

Sociobiology, 2022
Secondary diaspore removal on the ground is an important ecosystem process. In this process, solitary foraging ants with larger body sizes are more efficient because they may remove more diaspores, faster and carry them at greater distances.

Role of plant functional traits in determining vegetation composition of abandoned grazing land in north-eastern Victoria, Australia [PDF]

, 2008
Question: In the Northern Hemisphere, species with dispersal limitations are typically absent from secondary forests. In Australia, little is known about dispersal mechanisms and other traits that drive species composition within post-agricultural ...

Dispersal of non-myrmecochorous plants by a >keystone disperser> ant in a Mediterranean habitat reveals asymmetric interdependence [PDF]

, 2012
In contrast to other plant-animal mutualisms, seed dispersal interactions, and particularly seed dispersal by ants, are generally considered asymmetric, non-specialized relationships in which dispersers depend less on plants than vice versa.
