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.

Caterpillars and fungal pathogens: two co-occurring parasites of an ant-plant mutualism. [PDF]

PLoS ONE, 2011
In mutualisms, each interacting species obtains resources from its partner that it would obtain less efficiently if alone, and so derives a net fitness benefit.

Natural-based antioxidants in cosmeceuticals: Extraction, bioavailability and skin ageing applications. [PDF]

Int J Cosmet Sci
Natural antioxidants from plants, fruits, seeds and fungi combat ageing by neutralizing free radicals, boosting collagen and protecting against UV damage. Enhanced by green extraction and smart delivery systems, they offer powerful anti‐inflammatory and antimicrobial benefits.

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”).

Coronavirus Detection in Bats Captured on the Deforestation Arc of Mato Grosso, Brazil. [PDF]

Zoonoses Public Health
ABSTRACT Coronaviruses (CoV) are RNA viruses associated with enteric and respiratory diseases and known for their emergence potential in humans and other mammals. CoVs originate from zoonotic transmission, in which bats are natural reservoirs. Previous studies suggest that CoV diversity is positively correlated with bat diversity, whereas anthropogenic

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.

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.

Vertically transmitted bacterivorous nematodes are consistent nest inhabitants in the Azteca-Cecropia ant-plant mutualism [PDF]

Scientific Reports
Nematodes play key roles in natural and agricultural ecosystems. They contribute to organic matter transformation and the stability of soil food webs. Beyond their free-living forms, many nematode lineages have evolved in close associations with insects,

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 ...
