Measuring the Effects of “Opportunistic Defense” of the Bracken Fern, \u3ci\u3e(Pteridium Aquilinum)\u3c/i\u3e by Patrolling Ants (Hymenoptera: Formicidae) at Pierce Cedar Creek Institute in South Central Michigan [PDF]

open access: yes, 2018
In this study we show that in South Central Michigan (Pierce Cedar Creek Institute) eight ant species patrol bracken fern (Pteridium aquilinum) during the sensitive crozier growth stage.

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

open access: yesbioRxiv, 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.

Chemoreceptor Evolution in Hymenoptera and Its Implications for the Evolution of Eusociality. [PDF]

open access: yes, 2015
Eusocial insects, mostly Hymenoptera, have evolved unique colonial lifestyles that rely on the perception of social context mainly through pheromones, and chemoreceptors are hypothesized to have played important adaptive roles in the evolution of ...

Apparently noninvariant terms of $U(N)\times U(N)$ nonlinear sigma model in the one-loop approximation

open access: yes, 2009
We show how the Apparently Noninvariant Terms (ANTs), which emerge in perturbation theory of nonlinear sigma models, are consistent with the nonlinearly realized symmetry by employing the Ward-Takahashi identity (in the form of an inhomogeneous Zinn ...

Fungi as mutualistic partners in ant-plant interactions

open access: yesFrontiers in Fungal Biology, 2023
Associations between fungi and ants living in mutualistic relationship with plants (“plant-ants”) have been known for a long time. However, only in recent years has the mutualistic nature, frequency, and geographical extent of associations between ...

Near Optimal Channel Assignment for Interference Mitigation in Wireless Mesh Networks [PDF]

open access: yes, 2016
In multi-radio multi-channel (MRMC) WMNs, interference alleviation is affected through several network design techniques e.g., channel assignment (CA), link scheduling, routing etc., intelligent CA schemes being the most effective tool for interference ...

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

open access: yesFEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Larger Seeds are Dispersed Farther: the Long-Distance Seed Disperser ant Aphaenogaster famelica Prefers Larger Seeds

open access: yesSociobiology, 2015
Seed dispersal by ants (myrmecochory) is an important life phase in flowering herbs of temperate deciduous forests, and long dispersal is basically preferable in terms of plant fitness.
