In contrast, improving grazing management across broad scales is likely to result in enhanced profitability and could also benefit native vegetation.
With the increasing availability of fully sequenced genomes across broad scales of phylogeny, it has become possible to systematically study the origin of new genes over time and thus revisit this question.
Despite their limitations, the primary benefit of observational studies is that they document patterns across broad-scale realistic natural conditions that can then be used to inform further experimental and modelling studies.
The wide range of methods used in sampling makes anything more than broad scale comparisons across the entire dataset difficult.
From this ground-breaking work, we have learned that the developmental "toolkit" of genes is mostly conserved across distantly related taxa and that phenotypic change across such broad scales is often accompanied by spatial or temporal changes in the expression of these conserved genes (Davidson 2001; Wilkins 2002; Carroll et al. 2005).
On a broad scale across all islands mitochondrial as well as nuclear diversity indices did not correlate with island size (i.e. island perimeter; (see Figure S4 [see Additional file 10]).
But at broad scales across the western US, a one-size-fits-all approach such as thinning would be not only logistically impractical, it would still not address the root cause of increased beetle outbreaks and wildfires: climate warming.
Invariance across the broad scales considered here indicates that relatively simple rules govern the phylogenetic branching and the unfolding of biodiversity.
The number of divergence events within host groups was many more than expected by chance revealing a pronounced pattern of repeated divergence of this trait within host groups and broad scale convergence across the radiation of feather lice.
Detecting broad scale spatial patterns across the South American rainforest biome is still a major challenge.
We conducted a broad scale phylogeographic analysis of the least salmonfly Pteronarcella badia (Plecoptera) across western North America.
