Many hypotheses address the associations of plant community composition with natural enemies, including: (i) plant species diversity may reduce enemy attack, (ii) attack may increase as host abundance increases, (iii) enemy spillover may lead to increased attack on one host species due to transmission from another host species, or enemy dilution may lead to reduced attack on a host that would o...

Background & Aim: Kazeroon, with an area of about 4060 km², is situated at 110 km in the west of Shiraz, Fars province, Iran. This area is important for plant biodiversity, due to the presence of some important habitats such as international Lake of Parishan in the southeast, woodlands of Quercus persica in the east and branches of Shahpoor river in the west of the region. Therefore, f...

The responsibility for protecting U.S. agriculture from pests and diseases is assigned by the Federal Plant Pest Act (FPPA) to the Animal and Plant Health Inspection Service (APHIS) of the Department of Agriculture. The Plant Protection Act (Title 7 U.S.C. Sections 7701 et seq.) gives Aphis statutory authority over genetically modified organisms (GMO), in effect assigning to APHIS a related res...

Abstract Nature has been a wellspring of therapeutic operators for a huge number of years and an exceptional number of present day drugs have been secluded from common sources. Higher plants, as wellsprings of restorative mixes, have kept on assuming a prevailing part in the support of human wellbeing since old circumstances. More than half of all cutting edge clinical medications are of...

Most ecologists believe that climate change poses a significant threat to the persistence of native species. However, in some areas climate change may reduce or eliminate nonnative invasive species, creating opportunities for restoration. If invasive species are no longer suited to novel climate conditions, the native communities that they replaced may not be viable either. If neither invasive ...

We evaluated the structure of intrapopulation howler monkey-plant interactions by focusing on the plant species consumed by different sex and age classes in continuous and fragmented forests in southern Mexico. For this we used network analysis to evaluate the impact of fragmentation on howler population traits and on resource availability and food choice. A total of 37 tree and liana species a...

climate change due to increasing the level of greenhouse gases including co2 is the main environmental issue of the world in the new century. one of the effective way for reducing atmospheric co2 is carbon sequestration by plants and soils. a vast area of iran has desert condition with special adapted plant species in which can be devoted for carbon sequestration. hammada salicornica as a shrub...

Predictive modeling of habitat distribution of range plant species and identification of their potential habitats play important roles in the restoration of disturbed rangelands. This study aimed to predict the geographical distribution of Artemisia sieberi and find the influential variables in the distribution of A. sieberi in the desert rangelands of central Iran. Maps of environmental variab...
