Course Description

Communication in biological systems and its application in a biorational control of pests


Ecotechnologies, third-level study programme


prof. dr. Andrej Čokl


Upgrading of the basic knowledge about communication processes in different biological systems and development of critical thinking and analytical approach to research in the field of communication and behaviour.


• Introduction:
Definitions, signals cost categories, evolutionary interests of signallers and receivers.
• Signalling when interests overlap:
signalling between relatives, begging, alarms, food calls.
• Signalling when interests diverge:
mating signals, insect songs, carotenoid pigmentation.
• Signalling when interests oppose:
aggressive signalling, the dominant frequency of frog signals, communication signals and predator - prey relations.
• Honesty and deception in communication networks:
eaves dropping in signalling interactions, third-party receivers and reliability.
• Communication in the selected group of invertebrates: signal emission, the role of
media, signal reception, neuronal analysis of information, the role of signals in behaviour, multimodality of communication,...
• Communication between cells: examples of selected neuronal networks.
