Biogeochemistry is a useful tool for assessing geochemical dispersion patterns. Sari Gunay epithermal gold deposit was selected in order to assess the application of biogeochemical exploration for gold in northwestern Iran. In this study, four sites were sampled in a profile perpendicular to mineralized vein with a control site two km far-off mineralized vein. A sample from each dominant plant ...

Abstract Context Forest biodiversity is closely linked to habitat heterogeneity, while forestry actions often cause homogenization. Alternative approaches even-aged management were developed restore heterogeneity at the stand level, but how their application could promote diversity landscape scale remains uncertain. Objectives We tested potential benefit of diversifying regimes increase landsca...

The concept of “vulnerable marine ecosystem” (VME) was included in United Nations (UN) General Assembly Resolution 61/105 as part an international effort to minimize the effects seafloor fisheries on high seas. However, defining a VME left be developed by technical guidance UN Food and Agricultural Organization. In that venue certain categories organisms were deemed indicator species, suggestin...
