Are Local Filters Blind to Provenance? Ant Seed Predation Suppresses Exotic Plants More than Natives [PDF]
, 2014 The question of whether species’ origins influence invasion outcomes has been a point of substantial debate in invasion ecology. Theoretically, colonization outcomes can be predicted based on how species’ traits interact with community filters, a process

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.

Reproductive ecology of Allmania nodiflora, Celosia argentea var. margaritacea, and Digera muricata (Amaranthaceae) [PDF]
Botanica Serbica, 2018 Allmania nodiflora, Celosia argentea var. margaritacea, and Digera muricata are annual herbaceous weeds which reproduce exclusively by seed. The plants appear in June, while flowering time is August-February in agricultural fields and August-October ...

First evidence of myrmecochory in fleshy‐fruited shrubs of the Mediterranean region [PDF]
New Phytologist, 1994 SUMMARYIn the mediterranean ecosystems of South Africa and Australia, the role of ants in the dispersal of seeds is well known and antagonistic interactions as well as myrmecochory occur. The high prevalence of seed dispersal by ants, relative so that by vertebrates, is viewed as evidence of adaptation to the nutrient poor soils typical of these ...

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

Research trends and gaps in ant-mediated seed dispersal: a review with emphasis on Brazilian biomes [PDF]
Brazilian Journal of BiologyThis scientometric review analyzes global research patterns on seed dispersal by ants (myrmecochory) from 2009 to 2019, with particular emphasis on geographic and methodological biases across Brazilian biomes.

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 ...

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 ...

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 ...
