Learning walks and landmark guidance in wood ants (Formica rufa)
We have examined a behaviour pattern in wood ants which in some respects resembles and in other respects differs from the learning flights of bees and wasps. Wood ants returning to their nest from a newly discovered food source turn back and look at landmarks near to the feeder, but the feeder itself does not attract sustained fixations. The frequency of landmark inspections is highest when the...
متن کاملThermoregulation strategies in ants in comparison to other social insects, with a focus on red wood ants ( Formica rufa group)
Temperature influences every aspect of ant biology, especially metabolic rate, growth and development. Maintenance of high inner nest temperature increases the rate of sexual brood development and thereby increases the colony fitness. Insect societies can achieve better thermoregulation than solitary insects due to the former's ability to build large and elaborated nests and display complex beh...
متن کاملWood ants (Formica rufa group) in managed boreal forests: implications for soil properties and tree growth
Mound-building ants, and especially wood ants (Formica rufa group), are wide-spread key species that affect ecosystem functioning in several ways in the boreal forests of Eurasia. Forest clear-cutting harms wood ants, but the colonies gradually recover and multiply as forest succession proceeds. Thus their impact on ecosystem functioning may change with stand age. The objectives of this thesis ...
متن کاملNests of red wood ants (Formica rufa-group) are positively associated with tectonic faults: a double-blind test
Ecological studies often are subjected to unintentional biases, suggesting that improved research designs for hypothesis testing should be used. Double-blind ecological studies are rare but necessary to minimize sampling biases and omission errors, and improve the reliability of research. We used a double-blind design to evaluate associations between nests of red wood ants (Formica rufa, RWA) a...
متن کاملThe binding and recall of snapshot memories in wood ants (Formica rufa L.).
Insects can locate spatial goals by means of 2-D retinotopic views of the surrounding landmarks, which they memorise from the vantage point of the goal. Wood ants acquire such snapshot memories while fixating conspicuous landmarks with frontal retina, and their snapshots extend horizontally at least 120 degrees into the periphery. Are spatially separate items within such an extended snapshot bo...
