High frequency audible calls in northern birch mice Sicista betulina in response to handling: effects of individuality, sex and body mass on the acoustics

Abstract Objectives This is the first study of the sonic and ultrasonic vocalization in a Dipodidae rodent.For the small-sized quadrupedal northern birch mouse Sicista betulina, phylogenetically related to the bipedal jerboas (Dipodidae), we report null results for ultrasonic vocalization and investigate the acoustic cues to individual identity, se

Tools for analysing fuzzy clusters of sequences data

BACKGROUND: Sequence analysis is a set of tools increasingly used in demography and other social sciences to analyse longitudinal categorical data.Typically, single (e.g., education trajectories) or multiple parallel temporal processes (e.g., work and family) are analysed by using crisp clustering algorithms that reduce complexity by partitioning c
