Interference competition can profoundly influence the outcome of species interactions and may lead to either coexistence or exclusion. Our understanding of how interference can lead to coexistence remains incomplete, particularly when interference fails to result in resource partitioning. I document a novel form of interference competition between an ant (Myrmecia pyriformis) and a social spider (Delena cancerides) with similar foraging patterns. Of 120 nest boxes occupied by D. cancerides in… 

Collective personalities: present knowledge and new frontiers

It is concluded that collective personality, as a framework, has the potential to improve the general understanding of how selection acts on intraspecific variation in collective phenotypes that are of key importance across arthropod societies and beyond.

For sparassids spiders without large SSD, lower mass and longer legs translate into lower energetic costs of running distances for males, due to their lighter mass.
