Parental care has been widely studied in birds and mammals, but variation in space use in family groups has received less attention, despite its potential importance for both survival and subsequent dispersal of offspring. In this study, we evaluate factors affecting postfledging family space...

It is an established fact that the spectacular bioluminescent displays of adult fireflies and glow-worms are used as courtship signals; however, the survival value of the glowing behavior of their larvae remained the subject of speculation for many years. Our study is the first that demonstrates...

Inbreeding depression has been hypothesized to drive the evolution of mating systems and dispersal. Some studies have shown that inbreeding strongly affects survival and/or fecundity, but other studies suggest that fitness consequences of inbreeding are less detrimental or more complex. We...
