灵山岛空气微生物含量的测定

用平皿自然沉降法测定灵山岛空气微生物及肠道致病菌,结果表明该岛处于空气微生物中-轻度污染状态,以轻度污染为主,其中细菌为主要成分,也舍少量肠病菌,空气微生物显出某种时空变化势态,且与气温、人群活动等因素相关,推测谈岛脆弱的生态环境易被外界干扰,应引起关注。     

Measuring short-term population mobility among indigenous Australians: options and implications

"Despite the fact that indigenous Australians are known to be frequently mobile over the short term, statistical information regarding this population movement is grossly deficient.... This paper examines various means by which short-term population movement can be quantified to yield aggregate indicators of demographic impact. First, census data are used to establish the rate and pattern of inter-regional, short-term displacement. This reveals regional urban centres as net recipients of temporary residents while most rural areas experience temporary absenteeism. Secondly, results from household surveys are reported stressing the importance of including visitors to households in the estimation of service populations. Thirdly, administrative data on occupancy in urban hostels are used to derive indicators of the duration of movement."     

垃圾和粪便快速除臭方法研究

研究了城市生活垃圾及粪便混合物中恶臭气体的脱除方法。利用所筛选的高效除臭菌种配成不同比例的菌剂,在自然通气的条件下脱臭,８～１２ｈ便可完全脱臭。脱臭后的干燥混合物经加工可用于制备高效生物有机肥料,具有较高的经济价值和应用价值。     

厦门浔江湾牡蛎养殖区弧菌研究

利用ＭＰＮ法及ＡＰＩ２０Ｅ系统对厦门浔江湾牡蛎养殖区的特牡蛎体、水体及底质三类榈进行弧菌分析。结果表明，三类榈的弧菌密度随季节呈春，夏〉秋，冬趋而变化。牡蛎体弧菌密度与水样、底质样弧菌密度之间的相关数值分别为０．８１４３和０．５９５５，二者都高于０．３２５，因此呈显著相关，而且前两者相关关系更密切。

The Drivers of Market Integration Among Indigenous Peoples: Evidence From the Ecuadorian Amazon

Knowledge of the driving forces behind indigenous participation in the market is essential for practitioners intending to integrate conservation and development policies in indigenous territories. Nevertheless, empirical research on the determinants of market integration among indigenous peoples is still scarce. This article uses household survey data and multivariate techniques to examine the drivers of market integration among indigenous groups in the Ecuadorian Amazon. We use multiple measures of market integration, including the sale of crops, timber, and wildlife; the use of credit; and participation in wage labor. The results show that the way in which indigenous peoples integrate into the market depends on their endowments of human, financial, and physical capital. More educated households are able to engage in commercial agriculture and nonagricultural wage work, whereas uneducated poor households in communities in conflict with outsiders are pushed to engage in poorly paid agricultural wage work and (often illegal) timber operations.     

Mapping urban Māori: A population‐based study of Māori heterogeneity

Urban Māori is a term that describes indigenous people in Aotearoa New Zealand living in urban environments. It includes Māori who hold traditional authority over land (mana whenua) and Māori who have moved away from their traditional homes (mātāwaka). This article describes the heterogeneity of the urban Māori population through the spatial analysis of iwi (tribal) census data for four urban centres. The results show complex variation in the distribution of mana whenua and mātāwaka populations and help to inform a discussion about the rights and interests of all urban Māori in the development and planning of cities, and subsequent policy responses.     

Kāhuli: Uncovering Indigenous Ecological Knowledge to Conserve Endangered Hawaiian Land Snails

Indigenous knowledge is a multilayered knowledge system that can inform contemporary management in both natural observations and cultural value. Centuries old observations preserved within song, chant, and story has been globally recognized as a resource to integrate with conservation efforts for endangered species. In the case of the endemic land snails, kāhuli, of the Hawaiian archipelago, there is a prominent cultural presence preserved in oral tradition and written records in 19th and early 20th century’s Hawaiian language newspapers. As we witness the dramatic decimation of one of the greatest models of species radiation, the unveiling of the repositories of indigenous knowledge is crucial for conservation of these endemic land snails. This paper reports on indigenous knowledge that informs about the cultural significance (i.e., poetic device, metaphorical role, importance to hula) and ecology of kāhuli, and how indigenous knowledge can contribute to conservation efforts of rare and endangered species.     

路南石林土壤微生物含量及其对土壤CO2浓度的影响

在植被生长缓慢的季节(1999 年12 月), 对石林地区红壤三个研究点土下20 ～ 60cm 不同深度土壤的温度、pH 、有机质含量、微生物含量和土壤CO2 浓度变化进行了研究。研究表明土壤CO2 浓度和土壤中有机碳含量没有直接的关系, 但是与土壤微生物含量(Mo)、土壤湿度(Mt)和土壤CO2 浓度有很好的相关关系。因此在植被生长缓慢的季节, 土壤微生物对土壤空气CO2 浓度变化的影响要远远大于来源于根系呼吸的比例。
