Our concepts of sound localization in the vertebrate brain are widely based on the general assumption that both, the ability to detect and localize air-borne sounds and the underlying neuronal processes, are homologous in archosaurs (and birds) and mammals. Yet, studies repeatedly report conflicting results on the neuronal circuits and mechanisms as well as the coding strategies between avian and mammalian model systems. I will argue that mammalian and avian phylogeny of spatial hearing is characterized by a convergent evolution of hearing air-borne sounds rather than by homology.

Chemical communication is the evolutionary oldest communication system in the animal kingdom. In amphibians, chemical signaling is well documented in caudates, but because anurans spend a lot of energy in acoustic signaling, chemical communication has received much less attention in this order. However, poison frogs for example use chemical communication during parental care behaviours: They transport their tadpoles to very small water bodies and chemically recognize and avoid cannibalistic tadpoles.

If only those behaviours evolve that increase the actor’s own survival and reproductive success, then it might come as a surprise that cooperative behaviours, i.e. providing benefits to others, are a widespread phenomenon. Many animals cooperate even with unrelated individuals in various contexts, like providing food or allogrooming. One possibility to explain the evolution of such apparently altruistic behaviour is reciprocity. In reciprocal cooperative interactions, individuals help those partners that have been previously cooperative and therefore exchange favours repeatedly.

Lecture | Students
Cognitive research on non-human animals has been, and will be, a flourishing field but surprisingly few studies have been conducted on farm animals. As a detailed understanding of the perceptive and cognitive abilities of non-human animals is necessary to understand their normal behavioural expressions and to avoid exposing them to mental distress, an approach towards the cognitive capacities of farm animals is crucial for progress in animal welfare related topics.

Pollination strategies of European orchidsOrchids display a wide variety of strategies for attracting insects that can act as pollen vector. During evolution the morphology of the orchid flower was adapted in various ways in order to match the preferences of the visiting insects. This resulted in different pollination strategies, from reward to deception and from allogamous to autogamous pollination.In this lecture the morphology of the orchid flower is discussed, followed by many examples showing the various relationships between orchid and pollinator.
