In seagrass systems, blade density can provide refugia for prey at fine scales, which are further embedded within broad-scale features such as variation in biotic (e.g., predator assemblages) and abiotic attributes (e.g., turbidity, salinity).
The conservation of the broad-scale features of the recombination landscape across divergent species strongly suggests that the recombination landscape in male meiosis is controlled in large part at the chromosomal level.
Generally, vertical sampling of rhyolite is limited to a certain stratigraphic interval because of its great thickness; this case study enabled us to illustrate not only localized deformation but also broader scale deformation features.
We quantified colour morph frequencies in eight populations of C. decresii and examined their relationship with geographic distance, genetic divergence, broad scale environmental gradients and microhabitat features, to elucidate the causes of geographic variation in polymorphism.
The use of broad-scale biodiversity features underestimated irreplaceability value at a fine scale in heterogeneous and fragmented portions of the landscape.
The seafloor morphology of the Kvarken area is characterized by broad-scale geomorphic features including mounds, plains, basins, and some sea valleys (holes).
For interpretation of broad-scale spatial features, there is little significance of these error envelopes; their areas are less than 0.5%% of the whole deposit.
Further, because site-level datasets often focus on relatively few sampled variables, these datasets will be far more useful for answering broad scale research questions when combined with complementary geographic information system (GIS) datasets, available at national scales for features such as land use/cover, climate, topography and atmospheric deposition, to name a few.
"Either broad scale or carefully targeted".
This proves its value on a broad scale," he said.
