Abstract Studies investigating host-parasite systems rarely deal with multispecies interactions, and mostly explore impacts on hosts as individuals. Much less is known about the effects at colony level, when parasitism involves host organisms that form societies. We surveyed effect of an ectoparasitic fungus, Rickia wasmannii , kin-discrimination abilities its ant, Myrmica scabrinodis identifying potential consequences social level subsequent changes in infiltration success other organisms....
Abstract Many parasites interfere with the behaviour of their hosts. In social animals, such as ants, parasitic interference can cause changes on level individual and also society. The ant-parasitic fungus Rickia wasmannii influences Myrmica ants by expanding host’s nestmate recognition template, thereby increasing chance colony accepting infected non-nestmates. Infected consistently show an increase alkane tricosane ( n -C23) in cuticular hydrocarbon profiles. Although experimental...
So far, besides some specialised Neotropical ant species of the genus Cephalotes Latr., Palaearctic Myrmica schencki Viereck, M. rubra (L.) and Tetramorium cf. caespitum were known to be, at least facultative, pollen-eaters. The present paper reports on nine other common occasionally feeding pine pollen: ruginodis Nyl., F. pratensis Retz., cinerea Mayr, clara For., sanguinea exsecta Lasius niger (L.), L. platythorax Seifert, fuliginosus (Latr.) re-confirms pollenivory schencki. Pollenivory...
Abstract Intra‐ and interspecific aggression is quite common in ants, from occasional conflicts to large‐scale territorial disputes. The “nasty neighbor” phenomenon describes the differential aggressive treatment of neighbors versus foreign intruders. Due fact that workers a given colony meet rival more often at food resources, they treat them as threats their colony. reverse can also happen: “dear enemy” effect arises when an already known treated less aggressively due accommodation, than...
1. The study of behavioural variability has a long research tradition in social insects. Because their contribution to division labour, between‐individual variations have been mostly studied within the worker caste. In contrast, level variation between queens much less studied. 2. ants, high could contribute ecological success invasive species by favouring colonisation new environments. 3. ant Linepithema humile (Mayr), we used standardised test assess plasticity and predictability activity...
Abstract Social insect colonies are known to be targeted by a wide variety of different parasites and pathogens because their high host abundance. However, within colony, the level risk exposure could vary among individuals depending on role. Unlike many parasites, which mostly target specific groups individuals, e.g. foragers, myrmecoparasitic fungus Rickia wasmannii infects entire ant colonies, being linked subtle changes in physiology, morphology behaviour. We investigated how respond...
Abstract Urban habitats represent an important challenge for many organisms. Besides the abiotic changes, urban are also characterized by changes in biotic conditions, such as a more uniform species composition and declining population sizes. For ants this can result dietary shortages. In our study, we tested whether ant colonies might suffer from restrictions carrying out common garden experiment which rural were exposed to high carbohydrate, protein, fat / protein diets. We investigated...
"One of the major evolutionary transitions is shift from solitary to social lifestyle, which involved a plethora behavioral and physiological changes in entities. Group living has several advantages as evolution collective defense mechanisms. It may also affect individual immune system either due efficiency defenses or because high transmission frequency pathogens. Individual consists innate acquired components. In insects, there are two signaling pathways (Toll Jak/Stat) that result...
