Communication is a necessity found even in the simplest forms of life. It typically develops between individuals of the same species or population in a nonverbal manner, through visual, olfactory, electrical, or acoustic signals. More rarely, forms of communication can also arise between different species through co-evolutionary phenomena of great […]

Karl von Frisch (1886–1982) was a professor of zoology at the University of Munich, and his favorite subject of study was bees. As a sensory physiologist and neuroethologist, he highlighted two key behaviours in bees that advanced scientific understanding: their spatial orientation and the secrets of their communication. For this […]
In Italy today, two different populations of this carnivore exist, both of which, however, eat very little meat and largely prefer vegetarian diets. Looking back, we see even more successive bear populations, with species spanning much of the Pleistocene, starting from its earliest part (Late Villafranchian, 1.8 million years ago). […]
Migratory birds have remarkably consistent departure times from their breeding and wintering areas year after year, so much so that we refer to “migratory calendars” that define their different populations. Long-distance migratory species are especially punctual in their arrival and departure, often occurring on the same day or within the […]
In every branch of science, a careful and complete description of observed phenomena must precede experimental study. The study of behaviour is certainly no exception to this requirement.When studying a species, however, achieving a comprehensive understanding of its behaviour is a challenging task. It requires patient observation and objective description […]
