Abstract:
... A new species from the extinct ant genus Eocenomyrma, E. groehnisp. nov., is described based on worker from the Baltic amber (Late Eocene, Priabonian stage, 33.9–37.2 Ma). It the most resembles E. orthospina Dlussky et Radchenko, 2006 by shape of the propodeal spines and by the general appearance, but well differs from the latter by structure of the frontal carinae, which merging with the rugae th ...

Abstract:
... Territorial battles among ants exhibit temporal and spatial patterns that self-organize, arising spontaneously from distributed decisions by large numbers of individuals. We describe agent-based models of inter-group fights in ants and show that two behavioral mechanisms that are rarely quantified have large effects on the dynamics of intraspecific battles; specifically, the pattern of search by u ...

Abstract:
... In this study, we compare and analyze different ant taxa hindwing morphologies with phylogenetic hypotheses of the Family Formicidae (Hymenoptera). The hindwings are classified into three Typologies based on progressive veins reduction. This analysis follows a revision of the hindwing morphology in 291 extant and eight fossil genera. The distribution of different Typologies was analyzed in the two ...

Abstract:
... Although visual cues are essential for navigation in ants, few studies address movement dynamics in ants when they search and forage after finding food in an unfamiliar environment. Here I introduced Japanese wood ants to an unfamiliar food location by capturing individuals leaving their nest. The food was located at the centre of a straight, narrow, open-top channel. Next, I determined the segmen ...

Abstract:

However, how these types of management affect important ecosystem engineers such as ants, are poorly understood.

Abstract:
... Behavioral manipulation of hosts by parasites is important to increase the parasite fitness. Some species within the genus Ophiocordyceps, notably pathogens of ants, induce changes in the host's behavior, leading the host to die outside the colony and locking its mandibles on the edge of leaves. This study was conducted in Massif of Baturité, and for the first time, we describe the interaction bet ...

Abstract:
... When aiming to assess the effects of elevation on animal diversity, many studies have been carried out in different vegetation types occurring across elevational gradients. Thus, it remains unclear if any changes observed in species richness are caused by factors directly associated with elevation or are caused by vegetation change across the gradient. Here, we disentangled the effects of elevatio ...

Beetles were the most favoured food item, followed by spiders, ants and the small mammal Notomys fuscus. Within the beetles, ground beetles (Carabidae) and darkling be ...

Abstract:
... The ecological effects of the keystone mutualism between sap-feeding insects have been evaluated from the individual to landscape scales, but these effects’ fine-scale variation has not been characterized well. Here, we tested a simple hypothesis that aphid-tending ants’ effect on plant herbivory should be stronger on small leaves, with a dataset that included 15,602 leaves of a widely distributed ...

Abstract:
... Ants have been shown to engage in symbiosis across the tree of life, although our knowledge is far from complete. These interactions range from mutualistic to parasitic with several instances of manipulation of host behavior. Nutrient contributions in these symbioses include both farming for food and nitrogen recycling by gut-associated microbes. Interestingly, the ants that are mostly likely to h ...

Abstract:

The nutritional needs of the fungus garden, and the absence of potentially deleterious substances from plants, are criteria for selection by foraging workers. This is supported by behavioral experiments using fungicide with baits (ci ...

A ubiquitous orientation cue like the geomagnetic field m ...

Abstract:
... Insect–plant interactions occur in several ways and have considerable environmental and ecological importance. Many feeding strategies have evolved among herbivorous insects, with host–herbivore systems likely being influenced by trophobionts with ants. We investigated how these interactions vary across elevation gradients by evaluating the structure of the herbivorous insect community and ants as ...
