Ecology Letters (2011) 14: 939–947 Abstract Tropical rain forests play a dominant role in
global biosphere‐atmosphere CO2 exchange. Although climate and nutrient availability …

Nearly every aspect of the cloud forest is affected by regular cloud immersion, from the
hydrological cycle to the species of plants and animals within the forest. Since the altitude …

Elevated nitrogen (N) deposition may increase net primary productivity in N‐limited
terrestrial ecosystems and thus enhance the terrestrial carbon (C) sink. To assess the …

The widespread occurrence of nitrogen limitation to net primary production in terrestrial and
marine ecosystems is something of a puzzle; it would seem that nitrogen fixers should have …

Aim Anthropogenic additions of nitrogen (N) are expected to drive terrestrial ecosystems
toward greater phosphorus (P) limitation. However, a comprehensive understanding of how …

Abstract Walker & Syers (1976) proposed a conceptual model that describesthe pattern and
regulation of soil nutrient pools and availability during long-term soil and ecosystem …

1 Forest inventory data were collected in 1988-89 from permanent plots in undisturbed
tropical forest along an altitudinal transect on the northern slope of Volcan Barva, Costa …

This article reviews literature and summarizes experiments to investigate the extent to which
productivity of tropical montane rain forests is constrained by low nutrient supply. On any …

Our knowledge of the ecology of tropical rain-forest trees is limited, with detailed information
available for perhaps only a few hundred of the many thousand of species that occur. Yet a …

1 Data on the composition, structure and diversity of plant communities were gathered along
a 1000-m altitudinal transect from tropical seasonal dry forest to cloud forest on calcareous …
