Concentrations of total N, chlorophyll <jats:italic>a<\/jats:italic> (a marker for the photobiont), ergosterol (a marker for the mycobiont), and thallus specific weight (TSW; thallus dry weight in relation to surface area) were quantified for each thallus to see how biont investments were related to thallus N concentrations. Thallus N ranged from 11 to 43\u2006mg g<jats:sup>\u22121<\/jats:sup> DW revealing a wider N concentration range in this lichen compared to other green algal lichen species. Both chlorophyll <jats:italic>a<\/jats:italic> and ergosterol concentrations increased with increasing thallus N, with a steeper increase of the photobiont marker. TSW was similar in all thalli without any significant effect of thallus N concentration, suggesting that thallus developmental patterns are similar in low and high thallus N concentrations. The relatively higher resource allocation to the photobiont in relation to the mycobiont with increasing thallus N concentrations is an indication of the capacity of <jats:italic>X. parietina<\/jats:italic> to meet the C demands associated with N assimilation. This result is also in agreement with the inter-specific resource allocation pattern for green algal lichens across the same N concentration range.<\/jats:p>","DOI":"10.1017\/s0024282904014598","type":"journal-article","created":{"date-parts":[[2005,3,1]],"date-time":"2005-03-01T09:40:23Z","timestamp":1109670023000},"page":"171-179","source":"Crossref","is-referenced-by-count":24,"title":["Responses of the lichen <b><i>Xanthoria parietina<\/i><\/b> (L.)
