To examine the diversity and abundance of mammals in the mountain forest ecosystems of southern mountainous areas in Anhui Province, a total of 121 cameras were installed at eight sample plots including two national and five provincial nature reserves and the Huangshan Mountain Scenic Area between July 2013 and October 2015. In total, 6,375 trap days and 1,361 effective independent photographs were collected. 19 species belonging to 5 orders and 12 families were recorded. The first five species of photographic rate and relative abundance index were Muntiacus reevesi, Sus scrofa, Macaca thibetana, Callosciurus erythraeus, and Arctonyx collaris. Except Macaca thibetana, the other four species among the five and Paguma larvata were widely distributed in mountainous areas of south Anhui Province. For those species under special state protection, the relative abundance index of Macaca mulatta was nearly two fifths of•生物编目•
The electrochemical behavior of erythrocytes (red blood cell, RBC) and leukocytes (white blood cell, WBC) has been investigated by cyclic voltammetry with a three electrode system. The anodic wave of leukocytes and erythrocytes appeared at 0.32 V and at 0.73 V (vs. SCE), on the first scan. No corresponding reduction wave was observed in the reverse scan. The effect of scan rate and temperature on the peak potential and peak current were examined. The experimental results show that the electrode redox processes of erythrocytes and leukocytes are totally irreversible. An electrochemical method to monitor the number of leukocytes and erythrocytes was proposed. The peak current resulted in a linear change for 6.21 × 10 4 -1.14 × 10 6 cells mL ¹1 of leukocytes and 7.2 × 10 8 -5.76 × 10 9 cells mL ¹1 of erythrocytes. The peak potential shifted negatively with increasing of concentration of erythrocytes and at the same time the morphological overlapping of erythrocytes was found. This may be due to the self-assembly of erythrocyte transmembrane protein (band 3 and glycophorin A) noncovalently associated.
Holocene geomorphic changes have fundamentally shaped the spatial-temporal distributions of prehistoric and historical settlements in North China. Through intensive field surveys and careful field examination of typical sedimentary sequences, we reconstructed the Late-Pleistocene and Holocene geomorphic history in the two major basins of the mid-lower Fen River, central-south Shanxi, China. Our first-hand data provides crucial information for reconstructing the dynamic relationship between the characteristics of Holocene geomorphic changes and settlement distribution patterns in the two basins from the Neolithic period to the Bronze-Age Xia-Shang Dynasties. In the Taiyuan Basin, due to river downcutting processes from the end of the Late Pleistocene to the Early Holocene, edge of the basin emerged and evolved into tablelands. The elevation of the flat lands atop the tablelands that was significantly above the level of floodwater provided an ideal environment for early settlements. The Holocene geomorphic changes are characterised by continous fluvio-lacustrine aggradation, and the central basin became void of human settlements due to uninhabitable hydrological and gemorphic conditions and especially due to frequent floods. Instead, most settlements were located along the basin, displaying a unique "around-basin" distribution pattern. In the Linfen Basin, following large-scale incision of the main channels and branches of the Fen River during the Late Pleistocene, platform-type plain with deep incised valleys was formed. Similar to the surrounding loess tableland, the central basin became an optimal environment for human activities and settlement construction, forming a "full-basin" like settlement distribution pattern that is distinctively different from the "around-basin" distribution pattern in the Taiyuan basin.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
