“…Studied colonies of the genus Formica responded to the extreme heat by changing their foraging patterns, redesigning their nests and rearranging the spatial and functional structure of the colonies. They also switched to a bimodal daily activity pattern with the maxima in the morning and in the evening and a prolonged daytime intermission (Zakharov and Zakharov 2014). Nevertheless, more studies should be conducted to be able to predict how ants and other insects from temperate climates can adapt their foraging behaviour to current climate change and to identify species and populations endangered by decline or extinction.…”

Climate change and the subsequent increase of global temperature are the most current and important threats to biodiversity. Despite the importance of temperature, our knowledge about the level of behavioural and physiological adaptations of ant species from temperate regions to cope with high temperatures is limited compared to the broad knowledge of typical thermal specialists from warmer regions. In the current study, we investigated the temperature-related foraging risk of xerothermic ant species from the temperate climate in Europe, Formica cinerea. Our aims were to check how an increase in external soil temperature affects the foraging activity of workers and how the temperature during development and worker age affects foraging activity in high temperatures. Based on our results, we can draw the following conclusions: (1) the majority of workers utilize a risk-aversive strategy in relation to foraging in high surface temperatures; (2) pupal development temperature affects the risk taken by adult workers: workers that developed in a higher temperature forage more often but for shorter intervals compared to workers that developed in a lower temperature; (3) age is an important factor in temperature-related foraging activity, as with increasing age, workers forage significantly longer at the highest temperatures. Our study is one of the first to assess the potential factors that can affect the foraging risk of ants from a temperate climate in high ambient temperatures. Significance statement Our study is the first direct test of workers' age and the development temperature of pupae on the thermal-related foraging strategy of adult F. cinerea workers. It shows that worker age and the development temperature of pupae interact to promote tolerance of thermal stress. We found that with increasing age, workers are prone to forage significantly longer at the highest and riskiest temperatures. Workers that developed in the high temperature (28°C) foraged more often but for shorter intervals compared to workers that developed in the lower temperature (20°C). Interestingly, the factor of age is more significant for ants that developed in the higher temperature of 28°C; the foraging time of these ants significantly increased with their age.

“…В зонах сильной рекреационной нагрузки рыжие лесные муравьи исчезают совсем или становятся очень редкими [8, 31, 34, 36 и др.]. Благодаря этим особенностям муравьи представляют собой весьма перспективный объект для мониторинга [11][12][13][14], тем более что многие признаки, характеризующие состояние отдельных муравейников и их комплексов (размеры, форма, число троп, степень зарастания, наличие повреждений и т. д.…”

Presented in the paper are the results of the evaluation of current conditions of the natural complexes of special protected areas in Sverdlovsk Oblast: Regional Natural Parks «Olen’i Ruch’i», «Reka Chusovaya» and «Bazhovskiye Mesta», Mineralogical Preserve «Rzhevskiy», and State Natural Reserve «Visimskiy». Communities of plants and aqueous invertebrates and Formica rufa ants were used as bioindicators. Areas under recreation load and conditionally undisturbed areas were compared.

“…Post flooding, workers of five South American ant species built earthen levees around their nest entrances; these levees prevent experimental flood waters from entering the nest [95]. During an extremely hot summer, Zakharov & Zakharov [96] observed Formica ants modifying their nests by building dense covers over aphid colonies and trails; these covers were thought to serve as thermal insulation [96]. These studies raise the intriguing possibility that ants may have techniques for adapting infrastructure systems following disturbances.…”

Both human and insect societies depend on complex and highly coordinated infrastructure systems, such as communication networks, supply chains and transportation networks. Like human-designed infrastructure systems, those of social insects are regularly subject to disruptions such as natural disasters, blockages or breaks in the transportation network, fluctuations in supply and/ or demand, outbreaks of disease and loss of individuals. Unlike humandesigned systems, there is no deliberate planning or centralized control system; rather, individual insects make simple decisions based on local information. How do these highly decentralized, leaderless systems deal with disruption? What factors make a social insect system resilient, and which factors lead to its collapse? In this review, we bring together literature on resilience in three key social insect infrastructure systems: transportation networks, supply chains and communication networks. We describe how systems differentially invest in three pathways to resilience: resistance, redirection or reconstruction. We suggest that investment in particular resistance pathways is related to the severity and frequency of disturbance. In the final section, we lay out a prospectus for future research. Human infrastructure networks are rapidly becoming decentralized and interconnected; indeed, more like social insect infrastructures. Human infrastructure management might therefore learn from social insect researchers, who can in turn make use of the mature analytical and simulation tools developed for the study of human infrastructure resilience.
