1.36times more nocturnal duetohigh humandisturbance.For example,in Polandwild boarsgo from48%nocturnal innatural foreststo90%nocturnal inurbanareas.Even activitiespeople considerrelatively innocuous,such ashikingandwildlife viewing,stronglyaffected animalsdaily rhythms.We thinkthat we re leavingno traceoften whenwereoutdoors,butwe canbe havinglasting consequencesonanimalbehavior,“says KaitlynGaynor,lead researcherfor thestudy.This isnot thefirst timeanimals havehad tolive atnight;duringthetime ofdinosaurs,they werealsonocturnal.Dinosaurs werethis ubiquitous（无处不在的），scary force,and onlyafter theirextinctiondid mammals（哺孚L动物）emerge intothe daylight,“Gaynor says.And nowhumans havetaken overandare pushingother animalsback intothe night.”Scientists suspectbeing nocturnalmay hurtthose specieshighly adaptedtothesun.They mightnotbe abletolivewell atnight,which wouldultimately hurttheir chancesof survivaland reproduction.Perhapseven morealarming effectscouldbeinthewider ecosystem.InCalifornia sSanta CruzMountains,coyotes havebeen morenocturnal inresponse tohikers andhavestarted toalter theirdiets fromdaytime prey,such assquirrels andbirds,to nocturnalprey,suchas ratsand rabbits.Exactly howecological munitieswill change,and whetherit willbe forbetter orworse,requires furtherstudy.Some nighttimeshifts may benefit bothanimals andhumans,Gaynor notes.For instance,tigers inNepalare avoidingpotentially deadlyconflicts withpeople asthey beemorenocturnal.Studies likethis onewill eventuallyhelp conservationmanagers makebetter decisionsabout howtoprotect ecosystems.11need to understand localdynamics toreally understandhowwe shouldbe changingmanagement ofwildlife populationsor humanactivities,“Gaynor notes,uOne potentialapproachmight beto managethe timingof humanactivities sothat weleave someofthedaylight for otheranimals.”
