Monoculture of leafcutter ant gardens. [PDF]

PLoS ONE, 2010
Leafcutter ants depend on the cultivation of symbiotic Attamyces fungi for food, which are thought to be grown by the ants in single-strain, clonal monoculture throughout the hundreds to thousands of gardens within a leafcutter nest.

Seeing Through an Ant's Eyes: Do Entomopathogenic Fungi Extend Their Cognition to Their Hosts?

Topics in Cognitive Science, EarlyView.
Abstract Post‐cognitivist approaches recognize cognition as a phenomenon that involves not just brains but all the sensorimotor apparatus of organisms. This means that brains are not always required for the emergence of cognition and that every organism can, in principle, be cognitive, unlocking a theoretical framework to explain the complex adaptive ...

Diet composition of an escaped captive‐born southern tamandua (Tamandua tetradactyla) in a nonnative habitat in Asia

Ecology and Evolution, 2022
Studies on the role of natural predatory instincts in captive‐born mammalian myrmecophagy are rare. Consequently, researchers rely extensively on case reports to learn more about the contexts in which predatory behavior occurs among such animals. In this

How wildlife respond to tropical cyclones: short‐term tactics and long‐term impacts

Biological Reviews, Volume 101, Issue 5, Page 2081-2102, October 2026.
ABSTRACT From butterflies to lizards and from sharks to seabirds, wildlife exhibit tactics to survive the impacts of tropical cyclones, also known as hurricanes, cyclones, or typhoons depending on where they occur. Some species seek refuge during the storm by moving, some remain in place and ride it out, and others move longer distances, avoiding the ...

Orchard netting impacts on biodiversity leading to cascading effects at the ecosystem level

Biological Reviews, Volume 101, Issue 5, Page 2448-2466, October 2026.
ABSTRACT Agriculture must ensure food production without further compromising the ecosystem functions upon which it depends. Agricultural practices should therefore avoid harming farmland biodiversity, especially of taxa that supply the key ecosystem services (e.g.

Chromosome Mapping of Ribosomal DNA Clusters in Four Leaf-cutting Ant Species of the Genus Acromyrmex, with Description of a Triploid Individual in A. laticeps

Sociobiology
The increase of cytogenetic data in the leaf-cutting genus Acromyrmex has shown interesting contributions to the evolutionary and taxonomic approaches, including the creation of a new genus and the description of chromosomal patterns allowing ...

Evolutionary patterns of proteinase activity in attine ant fungus gardens

BMC Microbiology, 2011
Background Attine ants live in symbiosis with a basidiomycetous fungus that they rear on a substrate of plant material. This indirect herbivory implies that the symbiosis is likely to be nitrogen deprived, so that specific mechanisms may have evolved to ...

Persistence without prosperity at the upper range margin: Elevation, microhabitat buffering and biotic pressure in a range‐expanding spider

Ecological Entomology, Volume 51, Issue 5, Page 926-943, October 2026.
Anthropogenic linear features facilitate high‐elevation colonization. Parasitoid pressure declines markedly with elevation. Cocoon damage increases despite reduced parasitism at high elevation. Abstract The upper elevational range limits of thermophilic arthropods reflect constraints on population persistence rather than simple presence.

Complex host-pathogen coevolution in the Apterostigma fungus-growing ant-microbe symbiosis

BMC Evolutionary Biology, 2006
Background The fungus-growing ant-microbe symbiosis consists of coevolving microbial mutualists and pathogens. The diverse fungal lineages that these ants cultivate are attacked by parasitic microfungi of the genus Escovopsis. Previous molecular analyses

Consistent root microbiomes across contrasting habitats in a wild perennial vine

Plant Biology, Volume 28, Issue 6, Page 1880-1898, October 2026.
Communities of bacteria and fungi associated with the roots are similar across diverse habitats in a wild plant. Abstract While we are beginning to understand that the plant microbiome is important for plant health, we still lack information about how plant microbiomes are shaped across environments and how they influence plant performance, in ...
