A temporary social parasite of tropical plant-ants improves the fitness of a myrmecophyte [PDF]
Naturwissenschaften, 2010 Myrmecophytes offer plant-ants a nesting place in exchange for protection from their enemies, particularly defoliators. These obligate ant-plant mutualisms are common model systems for studying factors that allow horizontally transmitted mutualisms to persist since parasites of ant-myrmecophyte mutualisms exploit the rewards provided by host plants ...

Journal of Ecology, Volume 113, Issue 8, Page 2187-2198, August 2025.Individuals who engage in multiple mutualisms often have to pay indirect costs because of the interference of one mutualism on another. We found that protective ants had a low but variable impact on pollination, especially on the flower visitation by bees and when EFNs are close to inflorescences.

Ant–plant relationships in an Amazonian rainforest understory: A network approach
Insect Conservation and Diversity, Volume 18, Issue 4, Page 681-687, July 2025.Tropical rainforest ants are abundant at the ground and canopy levels, but the understory is frequently neglected. Thus, we looked for ants nesting in this stratum in an Amazonian rainforest. Ants nest in the debris accumulated between the fronds of the palm tree Astrocaryum sciophilum or are associated with myrmecophytes (plants that shelter ant ...

Plant functional traits and the entangled phenotype
Functional Ecology, Volume 39, Issue 5, Page 1144-1159, May 2025.Read the free Plain Language Summary for this article on the Journal blog. Abstract Integrated phenotypes consist of multiple traits with enough coordination within and across organs to result in viable individuals, which not only respond to the surrounding environment but also modify it in myriad ways.

The Plant Journal, Volume 121, Issue 5, March 2025.SUMMARY Plant specialized metabolites play key roles in diverse physiological processes and ecological interactions. Identifying structurally novel metabolites, as well as discovering known compounds in new species, is often crucial for answering broader biological questions.

Foliar endophytic fungi as potential protectors from pathogens in myrmecophyticAcaciaplants [PDF]
Communicative & Integrative Biology, 2014 In defensive ant-plant interactions myrmecophytic plants express reduced chemical defense in their leaves to protect themselves from pathogens, and it seems that mutualistic partners are required to make up for this lack of defensive function. Previously, we reported that mutualistic ants confer plants of Acacia hindsii protection from pathogens, and ...

Urbanization drives partner switching and loss of mutualism in an ant–plant symbiosis
Ecology, Volume 105, Issue 11, November 2024.Abstract Mutualistic interactions between species underpin biodiversity and ecosystem function, but may be lost when partners respond differently to abiotic conditions. Except for a few prominent examples, effects of global anthropogenic change on mutualisms are poorly understood.

Comptes Rendus. Biologies, 2018 In an inundated Mexican forest, 89 out of 92 myrmecophytic tank bromeliads ( Aechmea bracteata ) housed an associated ant colony: 13 sheltered Azteca serica , 43 Dolichoderus bispinosus , and 33
