Seeing the forest with the leaves - clues to canopy placement from leaf fossil size and venation characteristics.

16 Dec 2009 Although a variety of leaf characteristics appear to be induced by light environment during development, analysis of ontogenetic changes in living broad leaved trees has suggested that a number of other traits also lumped into the classic 'sun' ... Read more...

Population genetics of the understory fishtail palm Chamaedorea ernesti-augusti in Belize: high genetic connectivity with local differentiation.

7 Oct 2009 BACKGROUND: Developing a greater understanding of population genetic structure in lowland tropical plant species is highly relevant to our knowledge of increasingly fragmented forests and to the conservation of threatened species. Specific studies ... Read more...

Patterns of colonization and spread in the fungal spruce pathogen Onnia tomentosa.

3 Oct 2009 The basidiomycetous fungus Onnia tomentosa is one of the most widespread root rot pathogens in North America. Although the disease is more severe on spruce and pine trees, this pathogen can infect several coniferous species. To study the population ... Read more...
