• The telegraph equation with a drift term to determine an asyunmetric randotn walkis applied to the beltavior of paramecia to acctxmulate at their optimal temperature inthe presence of tentpem-ature gradient. Frorn this equation, tlte 1'o[lowing two pointsare clarified; l, the stationary solution of the equation explains that the observed stationary distribution of the cells decreases exponential[y from their optimal position,and 2, on a kind of paramecium that begins to accumulate at the optimal temperatureafter the treaUntenU wit[t ribo{lavin, tlte calculated transition time from a randomdistribution to the stationary disLributioxa agrees with the observed transitiout time, 3[paramecium,change, l] optirnal' tifne, {l ri boflavinttelegraph equation, asyrnmetric random walk, directionaltemperature, thermotaxis, stationary distribution, transmtmon
