Fire and plant diversity at the global scale | Fire Research …
Given that fire is a global factor that has been affecting many regions around the world over geological time scales, we hypothesize that the fire regime should explain a significant proportion of global coarse-scale plant diversity. Location: All terrestrial ecosystems, excluding Antarctica.

We test to what extent mean environmental condi- tions and environmental heterogeneity are related to species richness in a regular geographical grid system (UTM) of 10 km ∞ 10 km in the NE Iberian Peninsula (i.e. Catalonia, ca. 31 900 km2). Species richness of each UTM quadrat was estimated by compiling a large database (more than a million records) from bibliographic …

Coarse Filter CI
Since inception of coarse/fine filter concept for conserving biological diversity (TNC 1982), there has been an evolution in interpretation and application of the concept. Originally (TNC 1982), the concept of conserving entire plant and animal communities in reserves was viewed as an efficient coarse filter approach to conserving biodiversity that

At the coarse scale (0.5 degrees), we found a positive effect of range in elevation on tree species richness. However, when measuring range in elevation using a fine-scale moving window of radius 500 m, we found a negative relationship with tree species richness. ... Empirical evidence includes negative relationships between small-scale soil ...

Global Change Biology | Environmental Change Journal
In rugged terrain, coarse-scale climate grids may not capture topographically controlled climate variation at the scale that constitutes microhabitat or refugia for some species. Although finer scale data are therefore considered to better reflect climatic conditions experienced by species, there have been few formal analyses of how modeled ...

In proposing a solution to the correspondence problem, Marr and Poggio suggested unidirectional, coarse-scale-to-fine-scale interactions. These interactions overcome stereo matching-range limitations built into the size-disparity correlation. In Marr and Poggio's cross-channel bootstrapping operation, mechanisms tuned to low frequencies ...

Modeling plant species distributions under future climates: …
Recent studies suggest that species distribution models (SDMs) based on fine‐scale climate data may provide markedly different estimates of climate‐change impacts than coarse‐scale models. However, these studies disagree in their conclusions of how scale influences projected species distributions. In rugged terrain, coarse‐scale climate grids may not capture topographically …

On green roofs, where many plant species are often deployed in monospecific patches, the implication is that while roof-level plant diversity may be high the improvement of ecosystem services that related to growth, biomass production and canopy characteristics may only occur when the species are planted in mixtures at fine spatial scales.
