Fish face a variety of stressors in nature, a prominent one being a predatory threat to which they respond with an adaptive behavioral response thus maximizing their chances of survival. A primary anti-predatory behavior is a startle response or C-start. This behavior is controlled by two large reticulospinal neurons, the Mauthner cells (M-cells) which integrate multimodal sensory inputs. Detecting a predator involves various sensory information such as visual and mechanosensory cues but also olfaction. Indeed, following an attack, an injured fish will release an alarm pheromone (Schreckstoff) and thus acutely alert close by conspecifics. However, whether the alarm pheromone in …


Statistical And Biological Analyses Of Acoustic Signals In Estrildid Finches, Moises Rivera Jun 2023

Acoustic communication is a process that involves auditory perception and signal processing. Discrimination and recognition further require cognitive processes and supporting mechanisms in order to successfully identify and appropriately respond to signal senders. Although acoustic communication is common across birds, classical research has largely disregarded the perceptual abilities of perinatal altricial taxa. Chapter 1 reviews the literature of perinatal acoustic stimulation in birds, highlighting the disproportionate focus on precocial birds (e.g., chickens, ducks, quails). The long-held belief that altricial birds were incapable of acoustic perception in ovo was only recently overturned, as researchers began to find behavioral and physiological evidence …
