Seed mass and nutrient content in nutrient-starved tropical rainforest in Venezuela

Mean seed dry mass values and nutrient contents were determined for 27 species of trees and shrubs in Amazonian caatinga (a forest-type especially short of nitrogen) and for 11 species in adjacent much taller forest on less poor soil and subsequently compared.

Requirements of Gap-Demanding Species in Chalk Grassland: Reduction of Root Competition Versus Nutrient-Enrichment by Animals

An investigation into whether non-mycorrhizal species of chalk grassland gaps are limited by root competition or by additional soil factors such as nutrient enrichment by animal faeces.

Consistencies in post-dispersal seed predation of temperate fleshy-fruited species among seasons, years and sites

Seed predation of 12 fleshy-fruited species was recorded in experimental dishes under early successional forest in south-west Germany (four seasons 1992 and 1993) and in south England (summer 1995). The mean time for three or more seeds of a species to be removed was taken as a measure of granivore preferences. Correlations of these preferences with several physical and nutritional seed traits were tested.

IDENTIFYING AGGREGATION AND ASSOCIATION IN FULLY MAPPED SPATIAL DATA

Describes a clump recognition process that may be used to analyze fully mapped spatial data. Any given spatial pattern can be made less aggregated by replacing the closest-together pair of plants by a single individual at their centroid position. By repeatedly amalgamating pairs of individuals in this way, an initially aggregated pattern can be reduced to one indistinguishable from complete spatial randomness.

A comparison of 12 tree species of Amazonian caatinga using growth rates in gaps and understorey, and allometric relationships

The relative growth rate of saplings of 12 species from an oligotrophic lowland rainforest were measured in treefall gaps and understorey. Allometric relationships between the total leaf area (TLA) and height were dependent upon light conditions.
