Laboratory of Molecular BiotechnologyTasukuOGITAAssistant ProfessorKey word・Food immunology・Functional food science・Intestinal microbiota・Probiotics・Fermented foodIt is thought that exchange of intestinal microbiota acts as a key factor in health maintenance and promotion. The intestinal microbiota was thought to be a key factor related to the bioregulatoryfunction of food. Hence, we focused on identifying food contributing to health maintenance and promotion by studying the change in intestinal microbiota via intake of food.Effect of functional food on intestinal microbiotaABCDABCEvaluationofthebioregulatoryfunctionoffoodtoelucidatethemechanismunderlyingthisfunction.Hypoxia cell culture system (A）Analysis of intestinal microbiota by DGGE（B）Division of Animal ScienceImmunomodulatory function of probiotics(A）(B）Analysis of immune cellAnalysis of intestinal microbiota Immunohistological analysisAdipose tissueIntestinal tissueTo elucidate the mechanism underlying the bioregulatory function of foodEvaluation of bioregulatory function in in vitro and in vivo19Laboratory ofZoologyShigeyukiIZUMIYAMAProfessorEcologyWildlifeJapanese macaqueGPSAsiaticblackbearWehavebeenresearchingecologyofwildlifeinhabitingincoldclimateoralpineenvironmentswherehabitatissevereoveralong-termperiod.Basedontheresults,wewereabletodeterminethepopulationdynamicsofterrestrialwildlifeduetoglobalclimatechangeandchangesinthenaturalenvironment.Human-wildlifeconflictshaveraisedpublicconcernsinJapan.Inparticular,damagesincroplandsandplantationscausedbywildanimalshavebecomeaseriousprobleminsmallvillagesinremotemountainareas.Tosolvetheseproblems,itisnecessarytounderstandrelationshipsbetweenhumanandwildlife,andtomanagewildlife,theirhabitatandhumanactivitiesbasedonreliablescientificevidences.Research themes：）Seasonal and altitudinal migration of Japanese macaque in theNorthern Japan Alps.）Seasonal migration of sikadeer in the Japan Alps.）GPS tracking of Argali (Ovisammon) in the Kyrgyz Republic: Addressing problem in wildlife management.）An evaluation of habitat selection of Asiatic black bear in a season of prevalent conflicts.ABCDABCAlpine zone in the Northern Japan Alps (Mt.
