The genetic diversity of rhizobia associated with Dalea purpurea Vent. in fragmented grasslands of west-central Minnesota.

Characteristics of the rhizobia associated with Dalea spp. in the Ordway, Kellogg-Weaver Dunes, and Hayden prairies.

Habitat fragmentation affects the biodiversity and function of aboveground organisms in natural ecosystems but has not been studied for effects on belowground species. In this paper, we consider the diversity of the rhizobia associated with the indigenous legume Dalea purpurea in 3 residual prairie areas in Minnesota and Iowa. Using Dalea purpurea as a trap host, 218 rhizobia were recovered fro...

Evaluation of Genetic Variation of Common Fig (Ficus carica L.) in West of Iran

This study describes morphological diversity and relationship of 14 cultivars and 133 wild fig accessions from central Zagros Mountains located in the west of Iran, based on 58 morphological characters. Among all characters, secondary drooping branches, number of bark tubers, shape of central lobe, length of central lobe/length of lamina, little lateral lobes, shape of leaf without lobed, fruit...

Evaluation antiviral activity of aerial parts extracts of Echinacea purpurea from Iran against HSV-1

Since years ago, phytopharmaceutical drugs have been used by various societies, as a traditional treatment. Echinacea purpurea (Asteraceae) is the best known of the dozen or so species of the genus Echinacea, a group of perennial prairie wildflowers native to the central grasslands of North American. E. purpurea is cultivated widely throughout the United states, Canada and Europe, although it h...

Consequences of elevated temperatures on legume biomass and nitrogen cycling in a field warming and biodiversity experiment in a North American prairie

Increases in global temperature are likely to have effects on the nitrogen cycle, including thosemediated through effects on legumes, which have a role in the N cycle by fixing N2. These effects may alter plant functioning and community structure, especially in N-limited ecosystems.Wemanipulated temperature and plant diversity in the field to investigate the effects of elevated temperature on a...
