Trematode genetic patterns at host individual and population scales provide ins...
Correia, Simão; Fernández-Boo, Sergio; Magalhães, Luísa; de Montaudouin, Xavier; Daffe, Guillemine; Poulin, Robert; Vera, ManuelMultiple parasites can infect a single host, creating a dynamic environment where each parasite must compete over host resources. Such interactions can cause greater harm to the host than single infections and can also have negative consequences for the parasites themselves. In their first intermediate hosts, trematodes multiply asexually and can eventually reach up to 20% of the host's biomass. In most species...
A niche perspective on the range expansion of symbionts
Mestre, Alexandre; Poulin, Robert; Hortal, JoaquínRange expansion results from complex eco-evolutionary processes where range dynamics and niche shifts interact in a novel physical space and/or environment, with scale playing a major role. Obligate symbionts (i.e. organisms permanently living on hosts) differ from free-living organisms in that they depend on strong biotic interactions with their hosts which alter their niche and spatial dynamics. A symbiotic l...
