Chickpea (Cicer arietinum) is the second most widely grown legume worldwide and is the most important pulse crop in the Indian subcontinent. Chickpea productivity is adversely affected by a large number of biotic and abiotic stresses. MicroRNAs (miRNAs) have been implicated in the regulation of plant responses to several biotic and abiotic stresses. This study is the first attempt to identify c...

Mangrove forests, important tropical coastal habitats, are in decline worldwide primarily due to removal by humans. Changes to mangrove systems can alter ecosystem properties through direct effects on abiotic factors such as temperature, light and nutrient supply or through changes in biotic factors such as primary productivity or species composition. Despite the importance of mangroves as tran...

Plant water use in drylands can be complex due to variation in hydrologic, abiotic and biotic factors, particularly near ephemeral or intermittent streams. Plant use of groundwater may be important but is usually uncertain. Disturbances like fire contribute to complex spatiotemporal heterogeneity. Improved understanding of how such hydrologic, abiotic, and biotic factors affect plant water use ...

the spherical mealybug (nipaecoccus viridis newsted) is one of the most harmful pest of citrus, oleander and mulberry in green space of shiraz region. this study was carried out to detect the population dynamics of this pest and the role of biotic and abiotic factors on it in 2007-2008. the spherical mealybug, in both years, started its activity from early may on citrus and oleander trees, but ...

Sustainable forest management strategies include emulating historical disturbance regimes to achieve multiple objectives. Partial-harvesting are used overcome conflicts between timber production and wildlife habitat conservation; however, the potential impacts on complex interactions ecological functions remain largely unknown. In 1984, a controlled experiment was initiated in dry forests of ce...
