In September 2009, one specimen of shrew gymnure (Neotetracus sinensis) and nine specimens of Chinese mole shrew (Anourosorex squamipes) were collected from Shikengkong, Nanling Nature Reserve in Guangdong Province. These are the first records of these two species from Guangdong Province. Measurements for the single female specimen of N. sinensis are: body weight (BVV) 35.4 g, head and body length (HBL) 126.0 mm, tail length (TL) 78.0 mm, hindfoot length (HFL) 24.6 mm, ear length 17.3 mm, condyloincisive length (CIL) 34.3 mm, and the dental formula is 3. 1.3.3/3. 1.3.3 =40. For A. squamipes, measurements (mean±SD) of male specimens (n=4) are BW 17. 0±2. 3 g, HBL 93. 9 ±3. 8 mm, TL 12. I ±1.3 mm, HFL 13. 5 ±0. 3 mm, and CIL 24. 6 ±0. 5 mm; those of female specimens (n = 5) are BW 19. 9 ±4. 0 g, HBL 97. 8 ±7.0 mm, TL 11. 8 ±0.9 mm, HFL 13.4 ±0.5 mm, and CIL 24. 9 ±0.5 mm. The dental formula is 1.2. 1.3/1. 1. 1.3 =26 for both male and female specimens. Source

In addition to ammonia-oxidizing bacteria (AOB) the more recently discovered ammonia-oxidizing archaea (AOA) can also oxidize ammonia, but little is known about AOA community structure and abundance in subtropical forest soils. In this study, both AOA and AOB were investigated with molecular techniques in eight types of forests at surface soils (0–2 cm) and deep layers (18–20 cm) in Nanling National Nature Reserve in subtropical China. The results showed that the forest soils, all acidic (pH 4.24–5.10), harbored a wide range of AOA phylotypes, including the genera Nitrosotalea, Nitrososphaera, and another 6 clusters, one of which was reported for the first time. For AOB, only members of Nitrosospira were retrieved. Moreover, the abundance of the ammonia monooxygenase gene (amoA) from AOA dominated over AOB in most soil samples (13/16). Soil depth, rather than forest type, was an important factor shaping the community structure of AOA and AOB. The distribution patterns of AOA and AOB in soil layers were reversed: AOA diversity and abundances in the deep layers were higher than those in the surface layers; on the contrary, AOB diversity and abundances in the deep layers were lower than those in the surface layers. Interestingly, the diversity of AOA was positively correlated with pH, but negatively correlated with organic carbon, total nitrogen and total phosphorus, and the abundance of AOA was negatively correlated with available phosphorus. Our results demonstrated that AOA and AOB were differentially distributed in acidic soils in subtropical forests and affected differently by soil characteristics. © 2015, Springer International Publishing Switzerland.

In order to evaluate the nutrient status and the heavy metal concentrations in the leaves of evergreen broad-leaved forest at Nanling Nature Reserve, the characteristics including contents, relationships and variations of N, P, K, Ca, Al, Na, Mg, Mn, Ni, Cu and Pb, were detected in the leaves of 16 dominant species in this reserve. The contents of N and P in leaves of the selected tree species were below the averages, while the concentrations of Ca, K and Mg were within its normal ranges of the terrestrial plants in China. The levels of Mn in the leaves detected were near the background values of Guangdong plants. Fortunately, the concentrations of Al, Ni, Cu, and Pb were within their respective normal ranges in plants. Based on the ratios of leaf N to P, the 16 species detected were all P-limited. Although these species are not suffering from Al, Ni, Cu and Pb at present, there is a potential risk from toxic metals activated by soil acidification caused by acid deposition in south China. Regular monitoring and research on the elemental concentrations in the leaves as well as forest soils in the reserve are scientifically necessary. Source

A new record of Myotis altarium was found in Guangdong Province when a survey was conducted in Nanling National Nature Reserve in September 2009. Its features are described in detail and compared with the original description. Comparisons between its morphological measurement data and published data, as well as the analytical results of its karyotype (2n =44, FN =50) , it can be identified as Myotis altarium. In this study, echolocation calls of Myotis altarium were found to be frequency modulated and of short pulse duration. We also found that the maximum frequency and pulse duration in holding status and flying status are greatly different. Source
