Betula nana L. is a deciduous shrub belonging to the Betulaceae family, which is recorded as endangered species in the Red List. The complete chloroplast genome of B. nana was reported in this study. The size of the B. nana chloroplast genome is 160,579 bp, with an average GC content of 36.1 %. This circular molecule has a typical quadripartite structure containing a large single copy region of 89,492 bp, a small single copy region of 19,343 bp, and two inverted repeat regions of 25,872 bp. It encodes an identical set of 114 unique genes, including 79 protein coding, 31 transfer RNA and 4 ribosomal RNA genes. The total of 20 genes were duplicated in the inverted repeats. A maximum likelihood phylogenetic tree supported that the chloroplast genome of B. nana is closely related to that of Ostrya rehderiana. © 2016, Springer Science+Business Media Dordrecht.

Nitrogen (N) is the most limiting nutrient for forest development. In this study, using a natural pH gradient, N and carbon (C) mineralization was investigated and the effects of soil pH as well as the total C and N contents and the soil C/N ratio were evaluated in forest soils after mountain closure in a karst region. The N availability was poor based on the low N mineralization potential (N0) and the low active fraction of soil total N (N0/total N), while high microbial decomposition activity was indicated by a high mineralization rate constant (kN). N0 was positively correlated with soil pH as well as the total C and N contents. Additionally, multiple regression analysis revealed that total CN (the product of the soil total C and total N contents) and the C/N ratio had more significant effects on N0 than soil pH. In contrast, the mineralization rate constants kN and kC were positively affected by soil pH. The results indicated that N availability was regulated by soil organic matter (SOM), while microbial activity was restricted by soil pH. Also, the lack of nitrification and the high C0/N0 ratio observed at soil pH <5.5 may be a strong indicator of alterations to the microbial composition prompted by severe soil acidification. Further research is required to determine the changes in soil microbial composition with the drop in soil pH and their effects on SOM decomposition and nutrient availabilities. © 2012 The Japanese Forest Society and Springer.

The present conditions and existing problems in the standardization of long-term located observation of forest ecosystems, and the importance, principle, objective and the overall design of constructing the standard system for the long-term observation of forest ecosystems in China were expounded and the overall design was made in six aspects, i. e. construction of the forest ecosystem research stations, the operational management, the criteria system for long-term observation, observation methods, data management and data utilization. The overall design is very important both theoretically and practically for guiding the research and formulation of criteria system, for accelerating the standardization process of long-term observation of forest ecosystems, impelling the healthy and orderly development of forest ecosystem research stations and the network among them and promoting the ability in network research.

Decline in crop pollinators has raised concern that crop productions of agri-ecosystems could be influenced. To date, most studies were carried out at field scales or landscape scales, but little is known regarding how pollinator abundance and the corresponding pollination services vary at growing region scales. Therefore, investigations were conducted to explore the pollinator abundance and reproductive success of Camellia oleifera Able., between the s'tree primary growing region and the plateau growing region. The abundance of solitary bee Andrena camellia Wu., declined from the primary region to the plateau region, whereas the abundance of social wasps increased. Honeybees and flies occasionally visited the flowers in both regions, but their visit densities were notably low. Among those species, only solitary bee was effective in transferring pollens. Pollinators deposited approximately 9 pollen grains on the stigmas in the primary region, but deposited approximately 0 pollen grains in the plateau region. C. oleifera trees in the plateau region underwent a higher level of pollen limitation than those in the primary region due to a shortage of the legitimate pollinator, A. camellia. © 2013 Friends Science Publishers.

Anthropogenic disturbances have caused pollinator decline by affecting the abundance and diversity of foraging plants. Anthropogenic disturbances are also thought to drive pollinator decline by reducing nest site availability, but the exact mechanisms by which human activities influence nest site availability are not currently well understood. In this study, we investigated nesting site preference of underground bee Andrena camellia Wu in two orchards. Principal component analysis of environmental factors (bulk density, penetration resistance, water content and temperature) indicated that A. camellia preferred loose, moist and low-temperature habitats. The favored habitats were located at the bases of the foothills a long distance from human settlements. At the bases, favored nesting substrates decreased along the distance gradient, and nest densities of digger bees increased along the distance gradient. On the summit, however, nesting substrates were compacted, dried with high temperature regardless of distance from human settlements, and the nest densities were all low along the distance gradient. In summary, anthropogenic soil disturbances in the vicinity of human settlements threaten digger bees by altering soil characteristics. The conservation of the soil substrates is addressed in terms of its role in governing the population of digger bee A. camellia. © 2013 The Entomological Society of Japan.

We here present a molecular phylogenetic analysis of cultivated Zanthoxylum species which have a long history of cultivation both for economic and for chemical values in China. Three cpDNA markers, including matK, rbcL, and trnL-F, were sequenced, with the goals of untangling phylogenetic relationships and inferring biogeographic origin and patterns of distribution among Zanthoxylum species. Based on three cpDNA markers, 19 haplotypes with 64 polymorphic sites in Zanthoxylum provenances were identified in our study. A low genetic differentiation (GST = 0.271, NST = 0.373) was observed within Zanthoxylum provenances. Based on phylogenetic tree and haplotype network, all 19 haplotypes were grouped into six clusters. Our results also supported the hypothesis that the so-called “Green Huajiao” belongs to the species Zanthoxylum armatum rather than Zanthoxylum schinifolium. The results also revealed that haplotypes of two cultivated species, Zanthoxylum bungeanum and Z. armatum, most probably diverged during the Late Miocene. Ancestral area reconstruction indicated that cultivated Zanthoxylum species experienced multiple long-distance dispersal events and several vicariance events and the ancestors of Zanthoxylum first colonized Yunnan and Guizhou provinces (D). Accordingly, the current disjunct distribution of Z. bungeanum and Z. armatum may represent long-distance dispersal of ancestors popularly named “Dahongpao” and “Qinghuajiao,” respectively. It is concluded that cpDNA markers may provide a new conceptual and practical opportunity to evaluate genetic diversity and to identify local cultivars of Zanthoxylum, making it a valuable source to include into potential breeding programs. © 2016, Springer-Verlag Berlin Heidelberg.
