Human disturbances have created urban forests where introduced species are a dominant component altering the plant species composition of the forests. Little is known on how introduced plant species, compared to native species, influence ecosystem processes such as decomposition and the associated litter fauna in tropical urban forests. Puerto Rico has been disturbed mainly by human activities resulting in the cooccurrence of introduced and native species in Puerto Rican forests. This study compares litter decomposition and litter arthropods among two introduced pioneer plant species Spathodea campanulata Beauv. and Albizia procera (Roxb) Benth, and one native pioneer plant species, Schefflera morototoni (aubl) Maguire. We also compare the decomposition rate through mass loss to test the occurrence of Home Field Advantage (HFA) between the three plant species. The Home Field Advantage hypothesis suggests that litter decomposes faster in its place of origin.The following questions were addressed: (1) How do litter arthropods abundance, richness, and composition change between introduced and native species? (2) How do litter decomposition rates differ between native and introduced species? To answer these questions, nine plots were selected: three plots dominated by Spathodea, three plots dominated by Albizia, and three plots dominated by Schefflera. Within each plot, litterbags were placed simultaneously and retrieved after 25d, 100d, 175d, 250d, 375d, and 450d. Each bag was filled with 5g of litter from the tree plants (108 bags/plant species). This experimental design produced 54 litter bags/date, representing each of the six treatments from each of the study plots for a total of 324 litter bags. Litter mass loss was measured, and arthropod data was collected. Variations in the abundance, richness, and composition of arthropods associated with individual plots were determined using the Analysis of Variance (ANOVA), and differences in decomposition were also assessed using ANOVA.
