1. Self-organizing conflicts: Group assessment and the spatio-temporal dynamics of ant territory battles

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:
... 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:
... Our knowledge of the processes related to the expression of distinct phenotypes in ants has significantly increased in the past few years. However, myrmecologists still face significant difficulties while addressing distinct patterns related to reproductive biology in ants. In the present work, we provide a theoretical discussion on the current limitations found in the process of caste representat ...

Abstract:
... Despite the increasing number of studies dealing with interaction networks in the last few years, there is still a lack of knowledge about how their structural organization are affected by changes in binary or weighted data. To fill this gap, we collected ants foraging on plants with extrafloral nectaries in 10 sites within the Brazilian Amazon to evaluate if the generality, vulnerability, nestedn ...

Abstract:
... Some species of cynipid wasp engage in mutualisms with ants by producing nectar‐secreting galls, providing carbohydrates, and receiving protection from parasitoids. The galls are functionally similar to extrafloral nectaries, plant structures well known for their role in ant–plant mutualisms. Though not well known, nectar‐secreting galls may have important ecological and evolutionary implications ...

Abstract:
... It has been 55 years since Nikolaas Tinbergen formalized the field of ethology by identifying four types of inquiry that address the “how” and “why” of animal behavior from both a contemporary and historical perspective. This framework has been particularly useful in exploring eusocial behavior among insects, due to integration across levels of analysis and timescales of influence. Although the fo ...

Abstract:
... Insects are well known to orient using celestial cues. The pattern of polarised skylight is the dominant celestial compass information that insects use, which they detect using a specialised set of ommatidia. The number of ommatidia decreases with body size, and it is unknown how this reduction in the number of ommatidia affects the precision of orienting using celestial cues. We investigated this ...

Interspecific trade-offs in foraging strategies can facilitate species coexistence in diverse communities with overlapping resource use, especially in taxa with complex social-foraging strategies. The discovery-dominance trade-off hypothesis is often invoked to help explain coexistence of ant species that use overlapping food resources, wherein colonies of some species are better at collectively d ...

Abstract:
... One outcome of the extensive work on the ways that birds and insects use visual landmarks to return to a rewarded location is that they use landmarks differently. But this conclusion may have been reached because the almost exclusive training and testing of birds in small laboratory environments may prevent birds from using the view-matching strategies seen in insects. To test how birds use landma ...

Abstract:
... The strength of plant–animal diversity relationships tends to be idiosyncratic and, in many cases, its mechanisms are poorly understood. Consequently, the relevance of plant diversity patterns as surrogates of animal diversity patterns is still debated. We evaluated if ants and trees show congruent patterns of species richness and turnover at a regional scale, and the extent to which cross-taxon c ...

However, electronic devices often consist of multilayers, and the failure of the electronic devices mostly starts from the debonding of the layers because of poor interfacial adhesion and large mechanical mismatch. Herein, we introduce a fully organic and intrinsically stretchable elect ...
