abstract: the potato tuberworm, phthorimaea operculella (zeller), is an important insect pest of potato (solanum tuberosum l.) in the storage and field in most parts of the world especially in tropical and subtropical regions due to its close relationship with the host, high reproductive potential and high economic losses. information on host preference, life table parameters and digestive en...

The present study was conducted for the first time to investigate and identify the ecological quality status (EcoQ) of Gorgan Bay and also to emphasize the degree of agreement between the results of different benthic macrofauna indices, introduction of appropriate index and utilization of basic results in environmental management programs in the region. To do, 22 sites were selected and macrobe...

Soundscape analysis, using acoustic indices, provides researchers with valuable ecological information to assess biodiversity, species behavior, and noise pollution. In this study,  to analyze biophonies and anthrophony in six urban parks in  Isfahan city in spring, six acoustic indices, including Acoustic complexity index (ACI), Acoustic Diversity Index (ADI), Acoustic Evenness Index (AEI), an...

Forestry plans have been influential on tree species and planting in different ways, regulating tree species diversity. Investigation of the changes in tree species diversity and preservation livestock sustainability by using forestry inventory can be an appropriate tool for decision makers in management. Indicators such as the Shannon Wiener and Simpson indices can be used to study the variati...

In breeding programs, it is necessary having knowledge of the relatedness and genetic diversity in germplasm pools. The spread of cultivated regions and the high levels of production indicates citrus importance in the global economy. Therefore, 110 citrus genotypes were evaluated using 12 ISSR markers. Overall, 154 polymorphic bands were scored with an average of 12.8 alleles per primer. The po...

The genus Ganoderma belongs to Polyporales, well-known for its medicinal properties and as a plant pathogen. The aim of this study was to identify the genetic variation between populations of two Ganoderma lucidum Karst. complex isolates using RAPD. For this purpose, four populations of G. resinaceum Boud. and eight populations of G. lucidum collected and purified during 2011-2012, were studied...
