Mosquitoes are attracted to Plasmodium-infected birds

Parasites can manipulate their hosts to increase their transmission success. Avian malaria parasites (Plasmodium) are thought to alter the cues such as host odour, used by host-seeking mosquitoes. Bird odour is affected by secretions from the uropygial gland and may play a role in modulating vector-host interactions. The hypothesis tested was that mosquitoes are more attracted to the uropygial secretions and/or whole-body odour (headspace) of Plasmodium-infected house sparrows (Passer...

From groups to communities in western lowland gorillas

Social networks are the result of interactions between individuals at different temporal scales. Thus, sporadic intergroup encounters and individual forays play a central role in defining the dynamics of populations in social species. The rate of intergroup encounters was assessed for three western lowland gorilla Gorilla gorilla gorilla groups with daily observations over 5 years, and non-invasively genotyped a larger population over four months.
