Plant performance is determined by the balance of intra- and interspecific neighbors within an individual's zone of influence. If individuals interact over smaller scales than the scales at which communities are measured, then altering neighborhood interactions may fundamentally affect community responses. These interactions can be altered by changing the number (species richness), abundances (...

GWAS in out-crossing perennial crops is typically limited by insufficient marker density to account for population diversity and effects of population structure resulting in high false positive rates. The perennial crop oil palm is the most productive oil crop. We performed GWAS for oil-to-dry-mesocarp content (O/DM) on 2,045 genotyped tenera palms using 200K SNPs that were selected based on th...

The circulation of wheat products involves a number of different types of food-related enterprises, including planting bases, grain trading companies, warehousing enterprises, food processing plants, sales companies and so on. The centralized traceability architecture cannot meet the requirements such as transaction data security. While, the distributed traceability architecture faces the diffi...

Eastern hemlock (Tsuga canadensis (L.) Carr.) is an evergreen conifer that is widely dispersed in the northeastern United States. Loss of the hemlock component in the eastern forest due to the introduced hemlock woolly adelgid (Adelges tsugae) will have long-term consequences for terrestrial and aquatic ecosystems. Some of the functional attributes of hemlock (vertical structure diversity, ever...

Green space is important for the maintenance of the ecological dimension of a sustainable urban landscape. Therefore, in order to figure out the relationship between the greening of urban parks and bird diversity, we used 5 avian ecological diversity indexes, such as Species richness, Abundance, ShannonWeiner diversity index, Evenness, and Margalef’s richness indices, to evaluate the functional...

We study the consequences of introducing individual nonconformity in social interactions, based on Axelrod’s model for the dissemination of culture. A constraint on the number of situations in which interaction may take place is introduced in order to lift the unavoidable homogeneity present in the final configurations arising in Axelrod’s related models. The inclusion of this constraint leads ...

A high degree of topical diversity is often considered to be an important characteristic of interesting text documents. A recent proposal for measuring topical diversity identifies three elements for assessing diversity: words, topics, and documents as collections of words. Topic models play a central role in this approach. Using standard topic models for measuring diversity of documents is sub...

This document explains diversity related methods in vegan. The methods are briefly described, and the equations used them are given often in more detail than in their help pages. The methods discussed include common diversity indices and rarefaction, families of diversity indices, species abundance models, species accumulation models and beta diversity, extrapolated richness and probability of ...

Bed planted wheat systems offer a new alternative for the traditional wheat producer to provide opportunities for crop rotation, more efficient use of water, and new techniques of nutrient management. This study was conducted to determine if planting winter wheat (Triticum aestivum L.) in Oklahoma on raised beds can maintain grain yields while providing more options in the cropping system. Expe...

Plant-plant interactions that change along environmental gradients can be affected by different combinations of environmental characteristics, such as the species and planting density ratios. Suaeda salsa and Scirpus planiculumis are regionally dominant species in the Shuangtai estuarine wetland. Compared with non-clonal S. salsa, clonal S. planiculumis has competitive advantages because of its...
