Azteca ants repair damage to their Cecropia host plants [PDF]

Journal of Hymenoptera Research, 2021
Some Azteca ants are well-known symbionts that defend their Cecropia host plants against herbivory, although there is considerable variability in behavior among colonies, conditions, and species.

Volatile Organic Compounds in the Azteca/Cecropia Ant-Plant Symbiosis and the Role of Black Fungi [PDF]

Journal of Fungi, 2021
Black fungi of the order Chaetothyriales are grown by many tropical plant-mutualistic ants as small so-called “patches” in their nests, which are located inside hollow structures provided by the host plant (“domatia”).

Tissue culture of Cecropia glaziovii Sneth (urticaceae): vegetative micropropagation and plant regeneration from callus Cultura de tecidos de Cecropia glaziovii Sneth (Urticaceae): micropropagação vegetativa e regeneração de plantas via calos [PDF]

Ciência e Agrotecnologia, 2010
Cecropia glaziovii is a tree with used in Brazilian popular medicine. Methods allowing the clonal propagation of this species are of great interest for superior genotype multiplication and perpetuation.

The effect of symbiotic ant colonies on plant growth: a test using an Azteca-Cecropia system.

PLoS ONE, 2015
In studies of ant-plant mutualisms, the role that ants play in increasing the growth rates of their plant partners is potentially a key beneficial service.

Ant Diversity and Stratification in an Amazonian Rainforest. [PDF]

Ecol Evol
We examined the three strata of an Amazonian rainforest (e.g., the ground and leaf litter, understory and canopy) using only two sampling techniques and analyzed their functional traits. We identified 494 ant species from 10 subfamilies and 77 genera over ≈3.0 ha, showing that they are species rich and abundant, particularly at ground level.

Nitrogen fixation by diverse diazotrophic communities can support population growth of arboreal ants [PDF]

BMC Biology, 2022
Background Symbiotic ant-plant associations, in which ants live on plants, feed on plant-provided food, and protect host trees against threats, are ubiquitous across the tropics, with the Azteca-Cecropia associations being amongst the most widespread ...

Dynamics and drivers of fungal communities in a multipartite ant-plant association [PDF]

BMC Biology
Background Fungi and ants belong to the most important organisms in terrestrial ecosystems on Earth. In nutrient-poor niches of tropical rainforests, they have developed steady ecological relationships as a successful survival strategy.

Non-Native Plants Alter Bird-Plant Frugivory Network Structure in a Human-Modified Tropical Landscape. [PDF]

Ecol Evol
DNA metabarcoding of faecal samples from 21 frugivorous bird species in Gamboa, Panama, was used to assess how non‐native plants influence frugivory network structure. Non‐native species, though comprising only 28% of plants, reduced nestedness, increased connectance and modularity, and caused disproportionately high secondary bird extinctions while ...

Seed Dispersal as a Multiphase Process: Integrating Abiotic and Biotic Vectors Across Ecological Gradients. [PDF]

Ecol Evol
Raccoon specimen, seed disperser through endozoochory. ABSTRACT Seed dispersal is a dynamic process through which diaspores (seeds or seed‐bearing fruits) are detached from the mother plant, transported to different sites in the landscape that offer physical protection, competitive advantages, or lower predation risk.

Unlocking Tropical Forest Complexity: How Tree Assemblages in Secondary Forests Boost Biodiversity Conservation. [PDF]

Ecol Evol
Secondary forests are crucial for achieving COP15/16 conservation goals. An operational national approach was developed to identify and characterise forest ecosystems based on the dominant tree species in the canopy, serving as indicators for ecosystem extent and condition.
