A Total Ratio of Vegetation Index (TRVI) for Shrubs Sparse Cover Delineating in Open Woodland
Persian juniper and Pistachio are grown in low density in the rangelands of North-East of Iran. These rangelands are populated by evergreen conifers, which are widespread and present at low-density and sparse shrub of pistachio in Iran, that are not only environmentally but also genetically essential as seed sources for pistachio improvement in orchards. Rangelands offer excellent opportunities...
متن کاملHelminths in dogs belonging to people in a resource-limited urban community in Gauteng, South Africa.
One hundred and sixty-four faecal samples, 148 adhesive tape swabs and 132 blood samples were collected from dogs in Boksburg, Gauteng, to assess the prevalence of helminth parasites in the area. Sixty-nine of these dogs were also necropsied and helminths recovered from the gastro-intestinal tracts. Ancylostoma caninum was the most common helminth and was present in 88% of the dogs, followed by...
متن کاملThe Biomes and Vegetation of South Africa
At a global scale the vegetation of the world is sometimes described in terms of six Floristic Regions, often called the Floral Kingdom of the world. The distinction between regions is based on distinctive suites of flowering plants, taking into account those (particularly families) that are exclusive (endemic) to the region. Confined to South Africa is one of these distinct kingdoms; the Cape ...
متن کاملThe Influence of Vegetation Height Heterogeneity on Forest and Woodland Bird Species Richness across the United States
Avian diversity is under increasing pressures. It is thus critical to understand the ecological variables that contribute to large scale spatial distribution of avian species diversity. Traditionally, studies have relied primarily on two-dimensional habitat structure to model broad scale species richness. Vegetation vertical structure is increasingly used at local scales. However, the spatial a...
