✦ Synopsis

Buchbesprechungen 333 radiant, energy by the at,niospherc, the tjot,als of radiat ion for different, geographical lat,itudes. etc. There :we five major chapters t.it.led "The energy environment in xvhich we live", "Solar and t;hernial radiation". "Kildiat.ion instri1nlent.s". "Heat, transfer by convectZion", and '"en-methods in ecology", which should be extremely valuable t o biologists who are interested in ecology or t'he construction of units for cont'rolled environnient. Normally, most, aspects of thermal radiation are coniplctely disregarded in biological model experiments. Only cert,ain aspects of solar radiation are considered and t'hese are usually, a,t most, a very scanty reproduction of the na,tural environment. The suthor makes it clear that biology is by far a more difficult. subject t o do controlled experinwnts than physics.

As t.he book deals with both solar and 1.horma.l radistion, t.here are graphs showing the solar spect.rum as received outside the earth's at.mosphere and the absorption cliaracterist ics of the atmosphere for various wavelengt~hs of ultra-violet, visible or infra-red rays. Considerable attent,ion is givcn to the direct) capturc of energy, by solar radiation such as the capture of sunliglit~ upon various surfaces of the earth. thermal convection. etc. Figures are given f. i. for the energy capture of tbe upper itnd under sides of le;tves. and this is tmnslated to the various aspects of' a control environment sit,nation wlicre bot'h visible and infra-red thermal radiation emitted by the room. the atmosphere or the environmental chamber itself must be ta,kcn into cwnsidcration. In general, the basic concept' of the text' encompasses aspects of energy exchange in t.he biosphere which are nor~na.lly not a pa.rt, of the usual biological textbook. The book is of special value for t.he ecologically interested microbiologist.
