Within odonates, male mating patterns range from active mate search to long-term territorial defence of oviposition sites. In territorial species, males may use three mating tactics or strategies that may be determined environmentally or genetically: territoriality, non-territoriality, or reversible switches between the two. The tactic exhibited by a male in any given case is determined by the ...

Due to its conspicuous manifestations and its capacity to shape the configuration and dynamics of wild populations, territorial behavior has long intrigued ecologists. Territoriality and other animal interactions in situ have traditionally been studied via direct observations and telemetry. Here, we explore whether noninvasive genetic sampling, which is increasingly supplementing traditional fi...

In territorial Odonata, adult ?? may use two mating tactics that may be genetically or environmentally determined: territoriality and non-territoriality. The non-territorial tactic has been sometimes found to include 2 additional males: sneaking and wandering. The non-territorial ??, however, often have lower reproductive success than territorial ??. Studies on various Calopteryx spp. have repe...
