Interception efficiency was predicted as a function of the leaf area index and the canopy extinction coefficient. Leaf area index in turn was predicted as a function of thermal time, development stage and leaf longevity. Conversion efficiency was considered a function of photosynthetic pathway, atmospheric CO<sub>2</sub> concentration and temperature pre-history. The model was validated by predicting production from climatic data for eastern England in 1978. These predictions agreed closely with the measured primary production of both species in that year. Assuming a doubling of atmospheric CO<sub>2</sub> concentrations and a 3°C increase in air temperatures throughout the year the model was then used to predict, and analyse the causes of change in, production for the year 2050. The model suggests that although the productivity of the C<sub>3</sub> species will increase, due primarily to increased conversion efficiency through reduced photo respiratory losses, productivity of the C<sub>4</sub> species may increase similarly through the effect of increased air temperature decreasing the incidence of photoinhibitory damage and accelerating leaf canopy development. The potential advantages of analytic models in predicting effects of climate change on primary production are discussed.","AbstractOtherLang":null,"BibLvlCode":"AMS","StandardTitle":"The primary productivity of <i>Puccinellia maritima</i> and <i>Spartina anglica</i>: a simple predictive model of response to climatic change","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1990,"MonPub":null,"DateUpdate":"2003-10-01","DateCreate":"2001-06-06","SecASFANote":null,"ConfID":null,"PeerRev":0,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":10684,"PubliDate":1990,"Pagination":"33-39","XtraPublOfAnaID":null,"ISBN":"978-94-010-7397-4","Volume":"57","Issue":null,"BRefMon":10678,"BRefMonRR":"<b>Beukema, J.J.; Wolff, W.J.; Brouns, J.J.W.M.
