Leaf decomposition in a Mexican tropical rain forest

Leaf decomposition in five common species was studied in the Los Tuxtlas tropical rain forest, Veracruz state, Mexico. The species were: Nectandra ambigens (Blake) C. K. Allen, Pseudolmedia oxyphyllaria Donn. Sm, Dussia mexicana (Standl.) Harms, Ficus yoponensis Desvaux and Poulsenia armata (Miq.) S...
