Assessing the effects of field plot size and stand structure on forest inventory estimates derived from laser altimetry data
… parameters. However, the effects of varying plot size on the prediction errors are not well understood. We investigated the effects of plot size on prediction errors using lidar data for a western Montana forest using five sizes derived from stem-mapped field data and multiple regression …

An Assessment of Visual Encounter Surveys for an Elusive Species: The Dunes Sagebrush Lizard (Sceloporus arenicolus)
… separate VES methodologies were analyzed: 1) plot size: 200m x 200m; survey duration: 15 minutes, 2) plot size: 400m x 400m; survey duration: 60 minutes, and 3) plot size: 200m x 200m; survey duration: 30 minutes. The probability of detection, for S. arenicolus, was compared to two more …

An Evaluation of Unmanned Aircraft Systems' Ability to Assess Stripe Rust in Large Wheat Breeding Nursies
… (p</p> <p>In a second study, the effect of plot size (single-row, two-row and four-row) on relationship between visual and remote sensing data (DGCI and NDVI) was explored. We evaluated a panel of 13 genotypes preselected to range from 0 to 100% severity, planted in three plot sizes across …

Adoption Analysis and Impact Evaluation of Potato IPM in Ecuador
… of education, farming experience, wealth, plot size and farmer being sick due to pesticide use for each level of IPM adoption. Results indicate that farmers who were exposed to certain IPM information sources increased adoption of IPM practices on potatoes, but farmers\' education and …

Assessment of Soybean Leaf Area for Redefining Management Strategies for Leaf-Feeding Insects
… is unknown. This research (1) evaluated minimum plot size requirements for mechanically defoliated soybean experiments using the LAI-2000 Plant Canopy Analyzer, (2) compared LAI estimates among LAI-2000 detector types which respond to different wavelengths of light, (3) compared LAI-2000 …

Density and design: the impact of urban densification on design qualities in residential neighbourhoods
… changes in morphological patterns such as plot size or control and ownership of open spaces, result from higher density design and, that there are subsequent impacts on particular design qualities such as overall adaptability or biodiversity of the residential neighbourhood. An analytical …

Multifunctional woody polycultures and their influence on soil organic carbon
… were quantified on samples collected using plot- and grid-based approaches to understand their influence on soil organic carbon (SOC) change. Baseline soil samples were collected in the spring of 2015 from land that was managed for decades with row-crops before multifunctional woody …

Decision Support for Operational Plantation Forest Inventories through Auxiliary Information and Simulation
… the basis for investigating the effects of plot and stand-level inventory aggregations on predictions and projections of future forest conditions. Forest regeneration surveys are important for assessing conditions immediately after plantation establishment. An unmanned aircraft system was …

Family housing in San Fernando, the Philippines : tradeoffs and choices in the use of dwelling space
… households make, including land title, household size, plot size (and the uniform plot design in the resettlement site), and a desire for personal security against natural disasters. In this study we see how households can utilize their dwellings for small business activities to gain income with …

Effect of plant density on soybean seed yield and quality
… four times in a randomised block design. Plot size was 4 x 1.8 m. Seed yield was strongly related to total dry matter at the start of seed fill, which in turn was a function of the amount of photosynthetically active radiation (PAR) intercepted by the canopy. A green area index (GAI) of …

An Object-Oriented Approach to Forest Volume and Aboveground Biomass Modeling using Small-Footprint Lidar Data for Segmentation, Estimation, and Classification
… within-segment CHM variance, and average field plot size, were developed. Horizontal point samples were used to measure in-field volume and biomass, for 2-class (deciduous-coniferous) and 3-class (deciduous-coniferous-mixed) forest schemes. Per-segment lidar distributional parameters, e.g., …

Assessing shopping mall led urban restructuring in Lusaka: location factors and key actors.
… in Lusaka, the study identified five factors; plot size, access to major roads, market area, demographics and distance between shopping malls. The study established that these factors are well known by the developers and not the institutions that are mandated to regulate the process. In …
