Concentration of leaf pigments in native (<i>Anadenanthera colubrina)</i> and invasive (<i>Prosopis juliflora</i>) species in a tropical dry forest in Brazil across seasons: (A) chlorophyll <i>a</i> (Chl <i>a</i>); (B) chlorophyll <i>a</i>/<i>b</i> (Chl <i>a</i>/<i>b</i>); (C) chlorophyll <i>b</i> (Chl <i>b</i>); (D) chlorophyll/carotenoids (Chl/Car); (E) carotenoids (Car).

Abstract

<p>Values represent the average of replicates (n = 20±SE; invasive dry season n = 25±SE). Different letters denote statistical differences by Newman-Keul test with significance level of 5 percent between variables.</p
