A native of the Midwest, Mr. Gregor paints his highly chromatic "flatscapes" -- the carpetlike farmlands of Illinois -- from an aerial perspective, making complex color patterns of fields, rivers, barns, silos, houses, fences, trees and other prairie paraphernalia.
We analysed seasonal and spatial patterns of field use by generalised additive mixed models and multivariate procedures.
On top of this landscape template, man-made patterns of field sizes and hedgerows from before 1930 are still visible in the current differences of milk production intensity.
We introduce Ecobordure, a flora-based indicator designed to describe vegetation patterns of field margins and infer on drivers leading to these patterns, i.e. structure and management practices of field margins.
Our results demonstrate that Ecobordure is a simple, efficient and reliable indicator allowing users to characterize vegetation patterns of field margins and identify potential drivers leading to these patterns.
[ 3- 6] Although the Optic Neuritis Treatment Trial (ONTT) investigators categorized visual field defects, they did not use strict definitions for classification and patterns of field loss were qualitatively rather than quantitatively determined [ 7].
Innovative research and incorporation of knowledge gained from observed patterns of field-evolved resistance into future resistance management strategies will help maximize the benefits of current and future transgenic crops.
For a more accurate assessment of the patterns of field-based MVPA using the ActiTrainer monitor, a longer monitoring period [ 21] (including at least 1 weekend day) during different seasons [ 45] would be needed.
In our study, the subjective perception of local residents regarding the source of livestock odors and the fact that odor annoyance perceived by local residents over the course of the year is related to the seasonal patterns of field application of animal wastes, suggests that agricultural lands are the main source of odor in rural areas.
Although theory, small-scale experiments, and retrospective analysis of resistance monitoring data suggest that the refuge strategy has been useful (Gould 1998; Tabashnik et al. 2008a, 2009a), a more detailed analysis of the spatial distribution of Bt crops and refuges in conjunction with patterns of field-evolved resistance could help to more rigorously test the effects of refuges.
A chequer-board pattern of fields is characteristic of much of lowland Britain and other parts of western Europe.
