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. Grubb, P.J.; Coomes, D.A. 1997 PDF

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

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 … Continue reading IDENTIFYING AGGREGATION AND ASSOCIATION IN FULLY MAPPED SPATIAL DATA
