Individual rules for trail pattern formation in Argentine ants (Linepithema humile) [PDF]

, 2012
We studied the formation of trail patterns by Argentine ants exploring an empty arena. Using a novel imaging and analysis technique we estimated pheromone concentrations at all spatial positions in the experimental arena and at different times.

Some notes on matrix transforms of summability domains of Cesàro matrices

Mathematical Modelling and Analysis, 2010
In this paper sufficient conditions for a matrix M = (mnk ) (mnk are Cesàro numbers As n‐k, s ∈ C if k ≤ n and mnk= 0 if k > n) to be a transform from the summability domain of the Cesàro method Cα into the summability domain of another Cesàro method Cβ ,

Ant-Plant Relationships in a Re-Created Tallgrass Prairie [PDF]

, 2018
Relationships between the distributions of nesting ants and flora were investigated in a re-created tallgrass prairie located in northeastern Illinois. One-third of 167 randomly selected 1m2 quadrats in the prairie contained ant nests.

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

, 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.

Do bromeliads affect the arboreal ant communities on orange trees in northwestern Costa Rica?

PLoS ONE, 2022
Ants often interact with other invertebrates as predators or mutualists. Epiphytic bromeliads provide nesting sites for ants, and could increase ant abundances in the tree canopy.

Negative effects of ant-plant interaction on pollination: costs of a mutualism

Sociobiology, 2021
The mutualism of ants and extrafloral nectary (EFN)-bearing plants is known to reduce rates of herbivory. However, ants may have negative impacts on other mutualisms such as pollination, constituting an indirect cost of a facultative mutualism.

Native and invasive ants affect floral visits of pollinating honey bees in pumpkin flowers (Cucurbita maxima)

Scientific Reports, 2021
Global pollinator decline is a major concern. Several factors—climate change, land-use change, the reduction of flowers, pesticide use, and invasive species—have been suggested as the reasons.

Sanitizing the fortress: protection of ant brood and nest material by worker antibiotics [PDF]

, 2013
Social groups are at particular risk for parasite infection, which is heightened in eusocial insects by the low genetic diversity of individuals within a colony. To combat this, adult ants have evolved a suite of defenses to protect each other, including

Analysis of environmental indicators assessing industrial symbiosis and urban symbiosis for an improved indicator selection process: A scoping review

Cleaner Environmental Systems
Through innovative exchange of resources, industrial symbiosis can contribute to the circular economy and decrease environmental impacts. Similarly, urban symbiosis focuses on synergies involving cities.

Urban tropical forest islets as hotspots of ants in general and invasive ants in particular

Scientific Reports, 2022
Urbanization is a crucial driver of environmental and biodiversity change. It is suggested that urbanization favours generalist and invasive species and might harm specialists of natural and semi-natural habitats.
