Relative Contribution

Succession following deforestation in Neotropical forests has been investigated extensively, yet rarely have studies connected nutrient dynamics with vegetation. This study was conducted in lowland wet forests of Maquenque, Costa Rica. The objectives were (1) to compare carbon (C), nitrogen (N), and phosphorus (P) characteristics and understory vegetation diversity between regenerating forests and primary forests; and (2) to use these variables to evaluate P. macroloba’s successional role. Four 300 m2 plots were established in primary and secondary forests where P. macroloba was the dominant N-fixing tree. Soil and vegetation data were collected from 2008 to 2010. Values of indicators of C, N, and P cycle activity were generally greater in primary than in secondary forest soils. Efficiency of organic C use and the relative contribution of respiration and organic C to soil biomass were also greater in the primary forest. These trends corresponded with greater richness, biomass, and cover of total and leguminous plant species, greater volume of P. macroloba in primary stands, and greater density of P. macroloba in secondary stands. As cleared regions of former primary forest regenerate, P. macroloba is the important dominant N-fixing tree and a critical driver of C, N, and P recuperation and ecosystem recovery.

Two New Species

Two new tomentelloid basidiomycetes, Odontia aculeata and O. sparsa, are described from secondary forests of northeastern China. Odontia aculeata is characterized by resupinate, arachnoid and brownish basidiocarps, a hydnoid hymenophore, a differentiated dimitic hyphal structure in the rhizomorphs with clamp connections on the generative hyphae, a monomitic hyphal system in the subiculum and irregular subglobose basidiospores with verruculose ornamentation. O. sparsa is characterized by resupinate, arachnoid, continuous and brown basidiocarps, smooth or with sparsely distributed spines, a differentiated dimitic hyphal structure in the rhizomorphs with simple-septate generative hyphae, a dimitic hyphal system in the subiculum and verruculose basidiospores. Molecular phylogeny inferred from internal transcribed spacer (ITS) sequences data indicated that the two new species clustered with the other species of Odontia with strong support. These two new species are described and illustrated in this paper.
