The Author of this new volume on ant communication demonstrates that information theory is a valuable tool for studying the natural communication of animals. To do so, she pursues a fundamentally new approach to studying animal communication and “linguistic” capacities on the basis of measuring the rate of information transmission and the complexity of transmitted messages. Animals’ communication systems and cognitive abilities have long-since been a topic of particular interest to biologists, psychologists, linguists, and many others, including researchers in the fields of robotics and artificial intelligence. The main difficulties in the analysis of animal language have to date been predominantly methodological in nature. Addressing this perennial problem, the elaborated experimental paradigm presented here has been applied to ants, and can be extended to other social species of animals that have the need to memorize and relay complex “messages”. Accordingly, the method opens exciting new dimensions in the study of natural communications in the wild.

Would you ask a honeybee to point at a screen and recognise a facial expression? Or ask an elephant to climb a tree? While humans and non-human species may inhabit the same world, it's likely that our perceptual worlds differ significantly. Emphasising Uexküll's concept of 'umwelt', this volume offers practical advice on how animal cognition can be successfully tested while avoiding anthropomorphic conclusions. The chapters describe the capabilities of a range of animals - from ants, to lizards to chimpanzees - revealing how to successfully investigate animal cognition across a variety of taxa. The book features contributions from leading cognition researchers, each offering a series of examples and practical tips drawn from their own experience. Together, the authors synthesise information on current field and laboratory methods, providing researchers and graduate students with methodological advice on how to formulate research questions, design experiments and adapt studies to different taxa.

The Guest Editors would like to acknowledge and thank Veridiana Jardim (USP, Brazil) for her contribution to the elaboration of this Research Topic in relation with her doctorate studies.

Featuring essays from some of the most prominent voices in early medieval studies, Dating Beowulf playfully redeploys the word ‘dating’, which usually heralds some of the most divisive critical impasses in the field, to provocatively phrase a set of new relationships with an Old English poem. The volume argues for the relevance of the early Middle Ages to affect studies and vice-versa, offering a riposte to antifeminist discourse and opening avenues for future work by specialists in the history of emotions, literary theorists, students of Old English literature and medieval scholars alike. To this end, the essays embody a range of critical approaches from queer theory to animal studies and ecocriticism to actor-network theory.
