Somion occarium is a wood-decaying bracket fungus belonging to an order known to be rich in useful chemical compounds. Despite its widespread distribution, S. occarium has been assessed as endangered on at least one national Red List, presumably due to loss of old-growth forest habitat.

Unlabelled: Nitrogen (N) fixation in association with mosses could be a key source of new N in tropical montane cloud forests since these forests maintain high humidity levels and stable temperatures, both of which are important to N fixation. Here, nutrient availability could be a prominent control of N fixation processes. However, the mechanisms and extent of these controls, particularly in forests at different successional stages, remains unknown to date.

Testing the extent to which ecological communities are structured by deterministic (niche-based) assembly processes, resulting in predictable species abundance and composition, is a fundamental goal of ecology. Here we use a 10-year dataset of 55,156 lianas comprising 86 species in an old-growth tropical forest in Panama to test whether community assembly is consistent with niche-based assembly processes. We find that species diversity and community composition was maintained because species conformed to four general requirements of coexistence theory: (1) species have negative conspecific frequency-dependent feedback that control their local population size; (2) species have a stronger negative effect on their own population than that of heterospecifics; (3) the equilibrium frequencies of species correspond to their relative abundance; and (4) species have positive invasibility.

Examining whether nitrogen (N) enrichment promotes secondary tree growth in both young (YF) and old-growth forests (OF) is crucial. This will help determine how N addition influences plant carbon sequestration across successional phases in temperate forests. We conducted an eight-year N addition experiment (0, 25, 50, 75 kg N ha yr) in YF and OF in northeast China to investigate the effects of enhanced in situ N deposition on tree growth.
