Concerns about emerging vector-borne diseases are increasing as the nexus between humans, wildlife, and vectors shifts due to changes in land use management, climate, and biota. A range of complex ecological variables interact to shape the probability of spillover, but these factors can be challenging to map and model. Thus, it is increasingly necessary to explore the disease ecology of vectors and vector-borne diseases. Elucidating interspecific interactions between wildlife reservoirs and vector within the context of climate and landcover is essential knowledge for controlling vector-borne pathogen spillover. Here, we are introducing 3 ecologists and a range of ecological approach which focused on the complex of vectors, wildlife and environments; (1) measuring abilities of wildlife as tick carriers [Kandai Doi, Forestry and Forest Products Research Institute]; (2) utilising host-vector networks to identify high-risk vectors and forecast spillover pathways [Mackenzie Kwak, Hokkaido University]; (3) association between deer impact on the vegetation and tick abundance[Kei Suzuki, Kyushu Research Center, Forestry and Forest Products Research Institute], with a commentator Ryo Nakao [Hokkaido University]. This forum aims to provide the introduction and gateway for ecologist with an interest in the disease ecology of parasite and vectors.
