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.

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,

Frugivore richness poorly predicts seed dispersal effectiveness under climate change [PDF]

Scientific Reports
Animal-mediated seed dispersal underpins forest maintenance, yet climate change threatens this mutualism by reshaping plant-frugivore overlap. Most projections assume that frugivore richness and binary interactions adequately capture seed dispersal ...

Interação planta-inseto: Aspectos biológicos e ecológicos do mutualismo Cecropia-Azteca

EntomoBrasilis, 2015
Uma associação bem conhecida dentre as interações ecológicas é o mutualismo entre plantas do gênero Cecropia e formigas, na maioria das vezes pertencentes ao gênero Azteca.

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.

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.

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

Peptides as a Therapeutic Alternative Against Leishmaniasis: A Scoping Review. [PDF]

Chem Biol Drug Des
This scoping review of 79 studies identified 231 antimicrobial peptides with anti‐Leishmania activity, including natural‐derived and synthetic peptides (inspired by natural sources or developed through rational design). Most were evaluated in vitro against promastigote and/or amastigote forms, with synthetic peptides showing a more promising effect ...

Leaf Epidermal Features for Differentiating Cecropia pachystachya Trécul from its Adulterant Tetrapanax papyrifer (Hook.) K. Koch [PDF]

Brazilian Archives of Biology and Technology, 2023
In the quality control of herbal drugs, analysis of microscopy structures is crucial to detect any adulterants or substitutes. Microscopic analysis is considered one of the first pharmacopeial parameters of pharmacognostic identification.

Natural history notes on worker size, colony size, and nest structure of Azteca muelleri Emery, 1893 (Hymenoptera: Formicidae) in Cecropia glaziovii (Rosales: Urticaceae) from the Atlantic Forest

Entomological Communications, 2021
Mutualistic association between Azteca Forel, 1878 ants and Cecropia Loefl. plants are one of the most studied interactions in Neotropics, however, natural history studies of Azteca species still poorly investigated due to the great effort required to ...
