Adaptability of foraging trails inMessor barbarus

  • J. L. Reyes
Article

Summary

This paper studies the ability of the speciesMessor barbarus to adapt to new trail system conditions, with particular reference to the extreme changes in the environment caused by fire.

It was observed that trails established after the fire differed significantly from those used by the colony previously. Not all nest established new trails after the fire, since some re-used former trails. Similarly, a close relationship was observed between average trail width and density of vegetation, together with an increase in linearity and length of trails after the fire.

Adaptabilité des pistes trophiques chezMessor barbarus

Resume

Le but de cette étude est de montrer la capacité d'adaptation de l'espèceM. barbarus face aux nouvelles conditions du système de pistes suite aux changements produits dans l'environnement par le feu.

On constate que les pistes établies après le feu sont très différentes de celles existant auparavant. Tous les nids ne reconstruisent pas de pistes après le feu car certains d'entre eux réutilisent les précédentes. Il existerait un rapport entre la largeur moyenne de la piste et la densité de la végétation, ainsi qu'avec l'augmentation de la linéarité et la longueur des pistes après le feu.
