These findings suggest that ALAN-induced transformation of activity pattern of isopods is linked to the adoption of more prudent behaviors. A similar...

However, we still do not understand how spectral components of celestial cues and pauses in flight impact heading direction in flies. To assess individual heading, we began by testing flies in a rotating tether...

...Robin J. Southon; Andrew N. Radford; Seirian Sumner ABSTRACT Sex-biased dispersal is common in social species, but the dispersing sex may delay emigration if associated benefits are not immediately attainable. In the social Hymenoptera (ants, some bees and wasps), newly emerged males typically...

...Maria K. Oosthuizen ABSTRACT Both exploratory behaviour and spatial memory are important for survival in dispersing animals. Exploratory behaviour is triggered by novel environments and having a better spatial memory of the surroundings provides an adaptive advantage to the animals. Spatial...

..., likely established and maintained its cosmopolitan status via migration over large spatial scales. To perform long-distance dispersal, flies must actively maintain a straight compass heading through the use of external orientation cues, such as those derived from the sky. In this Review, we address how D...

This may be a general dispersal strategy for animals with no target destination. * Author for correspondence ( [email protected] ) Competing interests The authors declare no competing...

We used spiders as a model system to test how single investments in silk use – for dispersal or predator escape – affect individual performance.
