Ecological restoration of plant-pollinator interactions has received surprisingly little attention, despite animal-mediated pollination underpinning reproduction of the majority of higher plants. Here, we offer a conceptual and practical framework for the ecological restoration of pollination mutualisms. Through the use of targeted restoration plantings to attract and sustain pollinators and in...

Restoration interventions require knowledge on the suitability of seed sources. Provenance delineation for ecological restoration degraded environments has begun to incorporate genome-wide information adaptive variation, but this only been completed a small number plant species. Rarely is provenance using genomics approach applied species occurring across different habitats, and in context futu...

The main objective of current study was application of direct gradient analysis, to identify the most important environmental factors affecting the Morphological characteristics in plant medicinal Verbascum songaricum.In this study species were collected from Rangeland, Howz Vally, Gahiz, Semeiroom intrance and Ghadam places in Isfahan province  as well as Dena in Kohgiloye and Boyer Ahmad prov...

The trait-based approach shows that ecosystem function is strongly affected by plant functional diversity as reflected by the traits of the most abundant species (community-weighted mean, CWM) and functional dispersion (FDis). Effects of CWM and FDis individually support the biomass ratio hypothesis and the niche complementarity hypothesis. However, there is little empirical evidence on the rel...

Overgrazing affects plant communities, and is a significant disturbance factor in arid and semi-arid regions. The immediate changes of plant communities after overgrazing in the disturbed arid ecosystems of Iran have been poorly studied. We recorded data from 100 random samples before and after overgrazing in the Golbahar plain located in the northeastern Iran to determine the changes in the pl...

Background & Aim: The use of medicinal plants is an option for livestock farmers who do not want to use allopathic drugs under certified organic programs or cannot afford to use allopathic drugs for minor health problems of livestock. Thus, the main aim of this study is the identification of some ethnoveterinary medicinal plants of Tehran watershed and their medicinal effects on livestock.  Ex...

The methods employed in a restoration can impact the resulting plant community. This study investigated the effect of restoration method on several indices of plant community structure by comparing two restoration methods conducted over an 8-year period to a naturally colonized postagricultural field and a remnant grassland. The restoration methods included (1) distributing seed over fallow fie...

BACKGROUND Riparian forests provide ecosystem services that are essential for human well-being. The Pepital River is the main water supply for Alcântara (Brazil) and its forests are disappearing. This is affecting water volume and distribution in the region. Promoting forest restoration is imperative. In deprived regions, restoration success depends on the integration of ecology, livelihoods an...
