Suzuki Noriyuki, PhD
I am an evolutionary ecologist who uses insects as a model system. My specific focus is to understand cause and consequence of the evolution of host range since it is closely associated with species coexistence as well as phenotypic diversification. My main approaches are fieldwork and laboratory experiment, but I also adopt molecular techniques, mathematical models, and meta-analysis.

Research
Ecological specialization caused by reproductive interference
Closely related species often differ in the quality and breadth of resources exploited, but the actual mechanisms causing these differences are poorly understood. I focused on interspecific negative mating interaction, reproductive interference, which has been underestimated in the context of ecological generalization and specialization. My study system is the two sibling ladybird species that coexist in the same region in central Japan. Harmonia yedoensis is a specialist that preys only on pine aphids, which are highly elusive and nutritionally unsuitable for ladybird hatchlings (Noriyuki et al. 2011 Ecol Entomol; Noriyuki & Osawa 2012 Entomol Exp Appl), whereas H. axyridis is a generalist predator with a broad prey and habitat range. I showed that the generalist species is superior to the specialist species in terms of reproductive interference, suggesting that asymmetric reproductive interference from the dominant species may force the non-dominant species to become a specialist predator that exclusively utilizes less preferred prey in nature (Noriyuki et al. 2012 J Anim Ecol). This means that reproductive interference can cause an oviposition preference in insects that is not optimal for the survival and development of the offspring, as a result of maternal adaptive behavior that maximizes the mother’s own fitness (Noriyuki 2015 Pop Ecol).
Adaptation and constraint in trophic egg-laying
Mothers of some animals, such as true bugs and snails, produce non-developing eggs or egg-like structures for offspring nutrition. Several authors have suggested that such trophic egg-laying should evolve only when mothers cannot lay large egg size (morphological constraint hypothesis) and adaptive significance of trophic egg-laying was unclear. First, I showed that morphological constraint on egg size is weak at best in ladybirds that produce trophic eggs (Noriyuki et al. 2012 Pop Ecol). Next, I theoretically showed that trophic egg-laying is favored in heterogeneous environments when mothers cannot adjust egg size plastically. This means that trophic egg provisioning may be a flexible maternal adaptation to a heterogeneous environment rather than a response to a morphological constraint.
