Variation in wood density across South American tropical forests

Wood density is a critical control on tree biomass, so poor understanding of its spatial variation can lead to large and systematic errors in forest biomass estimates and carbon maps. The need to ...

Weak evidence of density dependent population regulation when using the ability of two simple density dependent models to predict population size

The relative importance of density dependence regulation in natural population fluctuations has long been debated. The concept of density dependence implies that current abundance is determined by ...
