Of course the ash tree, and the woodlands that it forms, are more than millennia-old assemblages of trees, shrubs and ground flora.
A growing number of places, from New York City to Sweden, are investing in everything from rooftop gardens to pollution-filtering assemblages of trees to reduce tainted runoff.
The structure, function, and ecosystem services of tropical forest depend on its species richness, diversity, dominance, and the patterns of changes in the assemblages of tree populations over time.
The empirical classification highlights assemblages of tree species, including dominant species, and corresponds well with broad environmental conditions.
Usually, an assessment of climate change impacts on forest species change is based on modeling, rooted on the approach of using climate envelopes of temperature and precipitation limits to define boundaries of tree species, or forest functional types that are supposed to be stable assemblages of tree species (Iverson et al. 2008; Sitch et al. 2008).
When comparing two typical forest composition, i.e. an assemblage of conservative trees (high wood density, seed mass, maximal stature and low specific leaf area) and an assemblage of pioneer trees (exact opposite trait composition), the pioneer assemblage recovers much slower.
We test hypotheses of diverging lineages identified through the mtDNA gene tree and nuclear clustering with recently developed statistics that quantify the degree of exclusive ancestry in an assemblage of gene trees [17].
We did this by investigating the departure from a null model capturing the number of codivergent events in the assemblage of reconciled trees for both DdDp and core-less genomes.
Like a tableaux designed by Henri Rousseau for Raymond Roussel, the jungle from his 1905 Palace of the Arabian Nights is a crazy assemblage of pasteboard palm trees, sliding panels of foliage, humanoid monkeys, dancing skeletons and a mechanised smoke-breathing dragon.
