The red-crowned crane (Grus japonensis (Statius Müller, 1776)) is a rare and endangered species that lives in wetlands. In this study, we used variance partitioning and hierarchical partitioning methods to explore the red-crowned crane-habitat relationship at multiple scales in the Yellow River Delta Nature Reserve (YRDNR). In addition, we used habitat modeling to identify the cranes' habitat d...

—Predictive models of aboveground biomass of nonnative Tamarix ramosissima of various sizes were developed using destructive sampling techniques on 50 individuals and four 100-m2 plots. Each sample was measured for average height (m) of stems and canopy area (m2) prior to cutting, drying, and weighing. Five competing regression models (P < 0.05) were developed to estimate aboveground biomass of...

In the zone of broad-leaved forests European Russia, steppe meadows have been preserved showing rich floristic composition and making a significant contribution to biological diversity territories. Bryansk oblast is one forest regions in Russia where such are found. Here, with high large number rare plant species survived. Trees from surrounding areas constantly encroaching on these meadows. Mo...

گیاه گز رودخانه ای در حاشیه رودخانه کارون رشد می کند. اندام بیرونی این گیاهان در زمان سیلابی باعث کاهش سرعت جریان و جلوگیری از فرسایش کناره ای می شود. اندازه گیری ضریب زیری گیاهان موجود در این سواحل و دشت های سیلابی و بررسی تأثیر آنها در کاهش سرعت و تنش برشی جریان از اهمیت خاصی برخوردار است. در این تحقیق با استفاده از مدل آزمایشگاهی به بررسی ضریب زبری گیاه گز رودخانه ای پرداخته شده است. این گیا...

This data article describes a facile method for production of an adsorbent from Tamarix hispida wasted wood and modified by lanthanum metal for fluoride ions removal from wastewater. The main characteristics of the adsorbent consist of BET surface area, functional groups, and elemental analysis is presented. The data for attenuating the pollutants from a real wastewater treatment which was prov...
