Forestland use right transactions (FURT) are mechanisms developed by China's central government to cope with the problem of fragmented forestlands stemming from Collective Forest Tenure Reform (CFTR). We hypothesize that the rate of FURT remains surprisingly low after the CFTR because of households' decision-making behavior, which depends on individual attitudes toward risks and benefits, namely risk preference. Game experiments were used to measure individual risk preferences in 301 rural households in Fujian Province, China. The results show that risk and loss averse households are less willing to participate in FURT, whether for renting-in or renting-out forestlands. When it comes to FURT contract choice, risk and loss averse households prefer to choose informal oral agreements with relatives and friends for short-term, relatively low, one-off payments. Our results also indicate that perceptions of secure forestland tenure could promote household's renting-in of forestlands and weaken the negative impact of household risk preference. Meanwhile, risk and loss averse sellers generally give relative high price evaluations on their forestlands, which inhibits their possibilities to successfully rent-out. This study contributes to a better understanding of the relationship between household risk preference and FURT decisions, and will help inform the design of alternative policies that could promote FURT in China.

[Display omitted] • The NASBA-LFD for detecting MrNV-chin was developed by amlification at 41 °C in a single tube within 90 min followed by hybridization. • The NASBA-LFD was specific for MrNV. • Sensitivity of NASBA-LFD was about 104 times higher in comparison to PCR-based detection. • The NASBA-LFD would be a simple, rapid and reliable method for detection of WTD. Nucleic acid sequence-based amplification (NASBA) provides a fast and convenient approach for nucleic acid amplification under isothermal conditions, and its combination with an immunoassay-based lateral flow dipstick (LFD) could produce a higher detection efficiency for M. rosenbergii nodavirus isolated from China (MrNV-chin). In this study, two specific primers and a labelled probe of the capsid protein gene of MrNV-chin were constructed. The process of this assay mainly included a single-step amplification at a temperature of 41 ℃ for 90 min, and hybridization with an FITC-labeled probe for 5 min, with the hybridization been required for visual identification during LFD assay. The test results indicated that, the NASBA-LFD assay showed sensitivity for 1.0 fg M. rosenbergii total RNA with MrNV-chin infection, which was 104 times that of the present RT-PCR approach for the detection of MrNV. In addition, no products were created for shrimps with infection of other kinds of either DNA or RNA virus, which indicated that the NASBA-LFD was specific for MrNV. Therefore, the combination of NASBA and LFD is a new alternative detection method for MrNV which is rapid, accurate, sensitive and specific without expensive equipment and specialised personnel. Early detection of this infectious disease among aquatic organisms will help implement efficient therapeutic strategy to prevent its spread, enhance animal health and limit loss of aquatic breeds in the event of an outbreak.

Understanding rural households' conservation attitudes is crucial to achieving biodiversity conservation effectiveness, and one underlying predictor of household conservation attitudes is social trust. This study examined the impact of rural households' social trust on their ecological protection attitudes based on 922 rural household data around 13 giant panda nature reserves in Shaanxi Province and Sichuan Province, China. The results show that: (1) Social trust has a significant positive impact on rural households' conservation attitudes. (2) Males' ecological conservation attitudes are influenced by all the social trust variables, whereas females' attitudes are influenced mainly by interpersonal trust (trust in neighbors and villagers). The conservation attitudes of households with higher education levels and higher family incomes are mainly affected by trust in government, while those with lower education levels and lower family incomes are more significantly affected by the trust in villagers and village cadres. The above conclusions are helpful to understand the influencing mechanism of rural households' conservation attitudes and improve the protection effects of nature reserves. [ABSTRACT FROM AUTHOR]

Simple Summary: The New Zealand white rabbit (Oryctolagus cuniculus) is one of the most important breeds of commercial and experimental rabbits in the world, and also one of the most raised rabbit breeds in China. Our goal was to develop a suite of microsatellite markers to aid future conservation genetics research for the Oryctolagus cuniculus breeds. Based on the genetic diversity of 130 New Zealand white rabbits, we obtained a set combination of 22 markers. Then, we performed a genetic analysis of 200 New Zealand white rabbits corresponding to two generations with this combination. It can be used to evaluate the breed conservation of rabbit germplasm resources. At present, there is an abundance of quality domestic rabbit breeds in China. However, due to the lack of technical standards for the genetic evaluation of rabbit germplasm resources, there have been a number of problems, such as poor breed conservation. By studying the genetic diversity of 130 New Zealand white rabbits (regardless of generation), we obtained the best simple sequence repeat (SSR) marker combination. We found that, when using microsatellite markers for the effective genetic evaluation of domestic rabbits, the number of records should be greater than 60 and the marker number more than 22. Through the comparative analysis of 30 combinations of 22 markers, the optimal combination of 22 markers was determined, and the 22 SSR polymorphic loci were distributed on different chromosomes. We performed a genetic analysis of 200 New Zealand white rabbits corresponding to two generations, using the best SSR polymorphic loci combination. There were no significant differences in the genetic diversity parameters between the two generations of rabbits (p > 0.05), indicating that the characteristics of this excellent rabbit germplasm have been effectively preserved. At the same time, we verified that the established method can be used to evaluate the breed conservation of rabbit germplasm resources. [ABSTRACT FROM AUTHOR]

Abstract: For the purpose of mangrove restoration in China, Sonneratia caseolaris has been introduced and planted in Guangdong Province outside and north of its native habitat, Hainan Province. We monitored the litter fall and forest structure of this S. caseolaris forest in Shenzhen City, Guangdong Province, China, from 1996 to 2005. The annual fluctuation in litter fall increased with increases in air temperature from spring to early summer, and reached a maximum in autumn when the fruits matured. The total litter fall was significantly affected by air temperature, day length, and evaporation, rainfall in the previous month and by typhoons. In 1998, the sixth year after cultivation, the total litter production of the mature S. caseolaris forest significantly increased. The mean annual total litter production during 1998–2005 was 15.1tha−1 yr−1, among which, leaves and reproductive materials contributed more than 80% of the total. During the ten years of study, the DBH (diameter at 1.30m from ground level) and tree height of S. caseolaris increased from 5.2cm to 18.3cm, and from 4.5m to 13.4m, respectively. The litter fall production was strongly correlated with forest structure parameters, such as DBH, tree height, and crown area. The R value (the ratio of the maximum total litter fall to the minimum in the same community during the investigation periods) of S. caseolaris in the present study was 1.98, indicating a low annual variation of litter fall during these ten years.

Climate change disproportionately affects natural resource-dependent communities in the ecologically vulnerable regions of western China. This study used the household livelihood vulnerability index under the Intergovernmental Panel on Climate Change (HLV-IPCC) to assess vulnerability. Data were collected from 823 households in Ningxia, Gansu, Guangxi, and Yunnan provinces, these being ecologically vulnerable regions in China. With a composite HLVI-IPCC and multiple regression model, the factors that affect households' adaptive capability to HLVI-IPCC was estimated. Results indicate that Ningxia is the most vulnerable community, while Guangxi is the least vulnerable community across all indices. Moreover, Gansu has the heaviest sensitivity and exposure to climate change, whereas Ningxia has the highest adaptive capability to climate change. In addition, the age of household head and distance of the home to the town center had significant negative impacts on households' adaptive capacity to HLVI-IPCC. The results also suggest that the HLVI assessment can provide an effective tool for local authorities to formulate prioritizing strategies with promoting climate-resilient development and increasing long-term adaptive capacity.

White tail disease (WTD), a major disease prevailing in the larval stage of Macrobrachium rosenbergii, caused by Macrobrachium rosenbergii nodavirus (MrNV) associated with extra small virus (XSV), led to the economic loss of shrimp industry in China. In order to establish a convenient, sensitive and selective molecular diagnostic method to detect MrNV and XSV for the Chinese shrimp (MrNV/XSV-chin), a reverse transcription loop-mediated isothermal amplification (RT-LAMP) assay combined with a lateral flow dipstick (LFD) method were developed. A set of four specific primers and a labeled probe were designed according to the six conserved gene sequence regions encoding for the MrNV capsid protein CP43 and the XSV capsid protein CP17. The detection of MrNV and XSV simultaneously by RT-LAMP was performed at 61 °C in a single reaction for 60 min followed by hybridization with an FITC-labeled probe for 5 min and visualized by LFD. The RT-LAMP-LFD assay had a sensitivity of approximately 100-fold higher than conventional PCR. In addition, the assay could detect MrNV/XSV-chin from limited amount of RNA extracts as low as 1.0 pg extracted from Macrobrachium rosenbergii. This assay was simple to use, required little instrumentation, and exhibited excellent specificity for the MrNV/XSV-chin compared with other shrimp viruses. In conclusion, a convenient, sensitive and selective practical molecular diagnostic method was developed with the potential for diagnosis and prevention of WTD., (Copyright © 2018 Elsevier Ltd.

Background: Containment of influenza A H1N1 virus spread was implemented successfully in Xiamen, with large-scale inoculation to reduce morbidity. To identify beneficial elements and to guide decision-making in epidemic containment, we analyzed the epidemiologic parameters and evaluated the control measures., Method: We determined various parameters from laboratory-confirmed cases, including incubation period, duration of illness and reproductive number (R0), and evaluated the control measures., Results: There were 1414 cases with dates of onset between June 14, 2009 and March 22, 2010. The incidence was 56.79/100,000, and mortality was 0.12/100,000. The incidence during the community epidemic phase was 6.23 times higher than in the containment phase. A total of 296,888 subjects were inoculated with domestic influenza H1N1 virus cleavage vaccine. An epidemic curve showed that vaccination in students cut the peak incidence of illness significantly. Men (relative risk (RR) = 1.30, 95% confidence interval (CI): 1.17-1.45) and persons aged 0-14 years were at greater risk of infection. The incidence increased with younger age (χ2 = 950.675, p = ∞). Morbidity was lower in urban than in rural areas (RR = 0.56, 95%CI: 0.50-0.62). The median incubation time was 2 days, median duration of symptoms was 7 days, and the within-school reproductive number was 1.35., Conclusion: Our analysis indicated that the characteristics of this novel influenza virus were similar to those of seasonal influenza. The principle of "interception of imported cases" applied at Xiamen ports, and vaccination of students effectively limited the spread of the influenza pandemic and reduced the epidemic peak.

Background: Little is known about risk factors for typhoon-related injury., Methods: On 10 August 2006, Typhoon Saomei (one of the strongest typhoons on record) struck Southern China. We conducted a census in Longhua Village, Fujian Province to assess typhoon-related injury, and carried out a matched case-control analysis to evaluate risk factors., Results: Of the 3002 residents interviewed, 136 (4.5%) were injured, and 7 were reported by family members to have died (2.3 per 1000). Injuries were highest with the first peak of wind speed. Living in houses directly facing the sea, compared with living in the last row of houses, was associated with an increased risk (relative risk = 18 [95% confidence interval (CI) = 5.7-55]). Important risk factors were failure to reinforce doors or windows (adjusted odds ratio = 13 [95% CI = 2.4-76]), staying in a damaged room (8.7 [2.5-31]), and staying near a window or door (12 [4.1-38])., Conclusions: Injuries with typhoon Saomei were related to both wind speed and failure to take specific preventive measures.
