The importance of parasite geography and spillover effects for global patterns of host–parasite associations in two invasive species
Abstract Aim Geographic spread and range expansion of species into novel environments may merge originally separated species assemblages, yet the possible drivers of geographic heterogeneity in host–parasite associations remain poorly understood. Here, we examine global patterns in the parasite asse...
