Compositional heterogeneity and outgroup choice influence the internal phylogeny of the ants

bioRxiv, 2017
Knowledge of the internal phylogeny and evolutionary history of ants (Formicidae), the world’s most species-rich clade of eusocial organisms, has dramatically improved since the advent of molecular phylogenetics.

Predation success by a plant-ant indirectly favours the growth and fitness of its host myrmecophyte [PDF]

, 2013
Mutualisms, or interactions between species that lead to net fitness benefits for each species involved, are stable and ubiquitous in nature mostly due to "byproduct benefits" stemming from the intrinsic traits of one partner that generate an indirect ...

Beneficial effects of a multifunctional strain of Purpureocillium lilacinum in strawberry plants

Studies in Fungi
The extensive use of agrochemicals poses significant risks to both environmental and human health. The fungus Purpureocillium lilacinum (Ascomycetes: Ophiocordycipitaceae), through its application, represents a promising biotechnological tool to reduce ...

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.

Convergent evolution of complex structures for ant–bacterial defensive symbiosis in fungus-farming ants

Proceedings of the National Academy of Sciences of the United States of America, 2018
Significance Animal–microbial mutualistic symbioses are important examples of evolutionary adaptation in which symbionts shape diverse traits of their hosts, from physiology to morphology; yet few examples are known of multiple convergences on identical ...

A mixed community of actinomycetes produce multiple antibiotics for the fungus farming ant Acromyrmex octospinosus [PDF]

, 2010
BACKGROUND: Attine ants live in an intensely studied tripartite mutualism with the fungus Leucoagaricus gongylophorus, which provides food to the ants, and with antibiotic-producing actinomycete bacteria.

The ANTS problem [PDF]

Distributed Computing, 2016
We introduce the Ants Nearby Treasure Search (ANTS) problem, which models natural cooperative foraging behavior such as that performed by ants around their nest. In this problem, k probabilistic agents, initially placed at a central location, collectively search for a treasure on the two-dimensional grid.

Trade-off in plant-ant interactions: seasonal variations [PDF]

Brazilian Journal of Biology, 2020
This work evaluated the effect of seasonality on ant-plant interaction in a Seasonally Dry Tropical Forests, using as an ecological model the species Ipomoea carnea subs. fistulosa (Convolvulaceae).
