Acta Botânica Brasílica, 2022 Studies about seed dispersal and germination are important to understand patterns of plant distribution and abundance, and help establish strategies for environmental conservation. We evaluated the role of two different dispersers, the ant Atta laevigata

Invasive acacias experience higher ant seed removal rates at the invasion edges [PDF]
Web Ecology, 2012 Seed dispersal is a key process for the invasion of new areas by exotic species. Introduced plants often take advantage of native generalist dispersers. Australian acacias are primarily dispersed by ants in their native range and produce seeds bearing a ...

Transcriptome analysis of Chelidonium majus elaiosomes and seeds provide insights into fatty acid biosynthesis. [PDF]
PeerJ, 2019 Background Elaiosomes are specialized fleshy and edible seed appendages dispersed by ants. Lipids are the primary components of elaiosomes. Chelidonium majus is a well-known plant, the seeds of which are dispersed by ants.

The Chemoreceptive Molecular Mechanism Underlying CSP-Mediated Recognition of Seed Elaiosome from <i>Stemona tuberosa</i> by Hornets. [PDF]
Genes (Basel)Background/Objectives: As crucial natural predators, hornets contribute to ecosystem function by preying on agricultural and forest pests and facilitating plant pollination. However, the predatory preference of hornets for honeybees poses a significant threat to honeybee pollination and the development of the beekeeping industry.

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 ...

Sociobiology, 2021 Eggs of some stick insects bear external appendages called capitula. Foraging worker ants attracted by capitula disperse eggs in a response similar to the responses of workers to elaiosome-bearing seeds of many plants.

Ecology, 2023 AbstractAnts and other insects are often a source of localized secondary dispersal for wind‐dispersed plants and thus play an important ecological role in their spatial dynamics, but there is limited information on how climate change will affect such dispersal processes.

Are post-dispersed seeds of Eucalyptus globulus predated in the introduced range? Evidence from an experiment in Portugal [PDF]
Web Ecology, 2018 Plantations of Eucalyptus globulus Labill. have been expanding rapidly worldwide. The species is considered invasive in several regions. While in the native range, post-dispersal seed predation is known to severely limit eucalypt recruitment, there is

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.

Ecophysiology of seed dormancy and the control of germination in early spring-flowering Galanthus nivalis and Narcissus pseudonarcissus (Amaryllidaceae) [PDF]
, 2015 Seed dormancy induction and alleviation in the winter-flowering moist temperate woodland species Galanthus nivalis and Narcissus pseudonarcissus are complex and poorly understood.
