Comparative Phenotypic and Genotypic Analyses of Salmonella Rissen that Originated from Food Animals in Thailand and United States

Salmonella enterica serovar Rissen has been recognized as one of the most common serovar among humans and pork production systems in different parts of the world, especially Asia. In the United States, this serovar caused outbreaks but its epidemiologic significance remains unknown. The objectives of this study were to compare the phenotypic (antimicrobial susceptibility) and genotypic attributes of Salmonella Rissen isolated in Thailand (Thai) and the United States (US). All the Thai isolates (n = 30) were recovered from swine faecal samples. The US isolates (n = 35) were recovered from swine faecal samples (n = 29), cattle (n = 2), chicken (n = 2), dog (n = 1) and a ready‐to‐eat product (n = 1). The antimicrobial susceptibility of isolates was determined using the Kirby‐Bauer disk diffusion method with a panel of 12 antimicrobials. Pulse‐field gel electrophoresis (PFGE) was used to determine the genotypic diversity of isolates. All Thai isolates showed multidrug resistance (MDR) with the most frequent antibiotic resistance shown against ampicillin (100%), sulfisoxazole (96.7%), tetracycline (93.3%), streptomycin (90%) and chloramphenicol (30%). About half of the isolates of USA origin were pan‐susceptible and roughly 30% were resistant to only tetracycline (R‐type: Te). Salmonella Rissen isolated from Thailand and the USA in this study were found to be clonally unrelated. Genotypic analyses indicated that isolates were clustered primarily based on the geographic origin implying the limited clonality among the strains. Clonal relatedness among different host species within the same geography (USA) was found. We found genotypic similarity in Thai and US isolates in few instances but with no epidemiological link. Further studies to assess propensity for increased inter‐regional transmission and dissemination is warranted.

Cooperation in private forestry of post-soviet system: Forest owners’ cooperatives in Lithuania

The current state of cooperation in private forestry in Lithuania is examined, with a focus on the analysis of objectives, organisational structure and the ways forest owners’ cooperatives operate. A postal survey has been used as a main research instrument, the questionnaire consisting of a series of multiplechoice close-ended questions. This paper provides insights into the state forest enterprises and other private companies operating in the private forestry sector, and places forest owners’ cooperatives in a broader context of the private forestry sector. A typical forest owner’s cooperative in Lithuania has up to 10 members and about 20 clients to whom services are provided. The leaders of cooperatives indicate that the optimal number of clients using their services should not exceed 40. The main stated objectives of cooperatives are the provision of services to their members under the most attractive conditions, uniting members, and earning a profit for the members. These activities of cooperatives revolve around timber harvesting and trade. It is concluded that the process of cooperation of private forest owners in Lithuania is rather slow, although positive development can be observed.     

Factors influencing stump sprouting by pondcypress (Taxodium distichum var. nutans (Ait.) Sweet)

Sprouting can be an important mechanism of regeneration in harvested cypress (Taxodium sp.) wetlands; however, limited information exists on factors influencing sprouting. We examined the influence of harvesting practices, tree size, and site conditions on stump sprouting in eight pondcypress (Taxodium distichum var. nutans (Ait.) Sweet) wetlands in Florida, USA. Stumps were cut at three heights: 20 cm below high water level, at high water, and 40 cm above high water. Half of each site was harvested using a sawhead feller and the other half using shearhead. We monitored sprouting for 2 years post-harvest. Stump height affected first year sprouting, but the effect disappeared during year 2. Felling equipment did not affect sprouting; however, the shearhead caused greater stump damage. Sprouting declined with increasing parent tree size; percentage of stumps with sprouts after 2 years was 68% for trees 10–14 cm dbh and 28% for trees 20–24 cm dbh. Stump sprouting ranged among sites from 23 to 54% after 2 years. Results indicate that sprouting may be an important, but inadequate, form of regeneration. At sites with short hydroperiods, dense understories, and/or predominance of trees greater than 20 cm dbh, reduced sprouting may occur, and planting seedlings may be beneficial.     

中美森林法比较及其对我国森林法修改的启示

通过比较中美森林法的历史和现状，指出森林法修改和完善的紧迫性且时机已经成熟，以及森林法修改要重视理论研究和实际情况调查。我国森林法修改和完善可以借鉴美国森林法中的森林生态系统管理等先进理念。对美国《国有林管理法》与《中华人民共和国森林法》的结构与体例、立法精神、科学的地位、公众参与等内容进行了比较研究，据此给出一些《中华人民共和国森林法》的修改建议。

我国林业CDM固C项目的前景、影响及相关对策

本文从林业的角度对《联合国关于气候变化的框架公约》，《京都议定书》的相关条款做了介绍，并对CDM（清洁发展机制)林业固C项目在我国开展的前景及影响做了分析。主要结论如下：1)CDM林业固C项目是我国林业发展的重大机遇，通过为林业争取国外资金、技术支持及促进生态效益补偿制度的建立，将有力促进我国林业展与生态建设。2)为了充分把握CDM林业固C项目的机会，需要对林业的固C总量及固C潜力，可纳入CDM的林业固C项目的类型与特征，合适的CDM固C造林技术及模式，C贮量测定的标准化以及CDM的运行机制等进行研究。3)建议通过国际合作研究培养相关人材，开展小规模的CDM固C项目试点，并通过相关部门积极申报CDM森林固C项目。
