  • 1 Jun. We published a new paper: Environmental DNA method for estimating salamander distribution in headwater streams, and a comparison of water sampling methods in PLOSONE. LINK Here, we concluded that eDNA methods could be used to determine the distribution of macroorganisms inhabiting headwater systems using samples from the surface of the water.

Research overview

Our research objective is to understand ecosystem and community dynamics in ecosystems. We are broadly interested in the ecology, especially, trophic interactions in food web and phenological dynamics of community. Also, we are interested in general biology and sciences, such as metabolic theory and biological stoichiometry, environmental pollution. Currently, our research themes are follows.

 

1) Food webs: spatial patterns of food webs, production, material cycling in aquatic ecosystems, food web analysis using multiple stable isotopes, food-chain length theory

 

2) Prey-predator interactions: microalgal communities and grazers interaction, habitat use of aquatic grazers, interactions between hosts and parasites

 

3) Environmental DNA: estimation of species distribution by eDNA,  biomass/abundance estimation by eDNA, high-thoughput sequencing for eDNA meta-barcording

 

4) Phenology and climate change: recent climate changes and the phenological timings of the organisms, mismatching in trophic interactions in response to climate change

 

5) Meta-analysis and big data analysis to synthesize ecological and biological themes: metabolic scaling and grow rate of organisms, predator effect on ecosystems, food-chain lengths and ecosystem history
