Microgeographic heterogeneity in spatial distribution and mtDNA variability of gray mouse lemurs (<Emphasis Type="Italic">Microcebus murinus</Emphasis>, Primates: Cheirogaleidae)

The objective of our study was to investigate the spatial distribution and genetic structure of a solitary primate at the microgeographical scale of adjacent local populations. We obtained spatial data and tissue samples for mtDNA analysis from 205 gray mouse lemurs (Microcebus murinus) captured along transects and within 3 grid systems within a 12.3 km² area in Kirindy Forest, western Madagascar. Our capture data revealed that, even though the forest was continuous, gray mouse lemurs were not evenly distributed, and that daily and maximum dispersal distances were significantly greater in males. The frequency distribution of 22 mtDNA D-loop haplotypes was highly skewed. Nine haplotypes were unique to males, indicating male-mediated gene flow from surrounding areas. The geographic distribution of haplotypes revealed that males were also more dispersed than females. Females with the same haplotype showed a tendency towards spatial aggregation, and the correlation between genetic and geographic distances was higher in females. In several areas of the forest, however, spatially clustered females were not of the same haplotype, and females were not always found in clusters. Hence, in contrast to suggestions from previous studies, matrilineal clustering is not the only way females are socially organized. In addition, our study revealed heterogeneity and patterns in population structure that were not evident at smaller spatial scales, some of which may be relevant for designing conservation strategies.Communicated by C.

The evolution of female social relationships in nonhuman primates

Considerable interspecific variation in female social relationships occurs in gregarious primates, particularly with regard to agonism and cooperation between females and to the quality of female relationships with males. This variation exists alongside variation in female philopatry and dispersal. Socioecological theories have tried to explain variation in female-female social relationships from an evolutionary perspective focused on ecological factors, notably predation and food distribution. According to the current “ecological model”, predation risk forces females of most diurnal primate species to live in groups; the strength of the contest component of competition for resources within and between groups then largely determines social relationships between females. Social relationships among gregarious females are here characterized as Dispersal-Egalitarian, Resident-Nepotistic, Resident-Nepotistic-Tolerant, or Resident-Egalitarian. This ecological model has successfully explained differences in the occurrence of formal submission signals, decided dominance relationships, coalitions and female philopatry. Group size and female rank generally affect female reproduction success as the model predicts, and studies of closely related species in different ecological circumstances underscore the importance of the model. Some cases, however, can only be explained when we extend the model to incorporate the effects of infanticide risk and habitat saturation. We review evidence in support of the ecological model and test the power of alternative models that invoke between-group competition, forced female philopatry, demographic female recruitment, male interventions into female aggression, and male harassment. Not one of these models can replace the ecological model, which already encompasses the between-group competition. Currently the best model, which explains several phenomena that the ecological model does not, is a “socioecological model” based on the combined importance of ecological factors, habitat saturation and infanticide avoidance. We note some points of similarity and divergence with other mammalian taxa; these remain to be explored in detail. Received: 30 September 1996 / Accepted after revision: 20 July 1997

Organization‐specific prosocial helping identity: Doing and belonging as the basis of “being fully there”

Identity theory and social identity theory focus on doing and belonging, respectively, but neither provides a complete picture of being “fully there” at work (Kahn, 1992 ). This three‐wave lagged field study links these two perspectives by proposing that beneficiary‐specific prosocial helping identity, met expectations for prosocial helping, and their interaction predict the strength of a contextualized, organization‐specific prosocial helping identity (OSPHI) targeted at those same beneficiaries and that OSPHI leads to positive employee work outcomes. Results provide strong support for the model and demonstrate that beneficiary‐specific prosocial helping identity had indirect relationships with intent to stay with the organization, experienced work meaning, and emotional exhaustion (negative), via OSPHI, only when met expectations for prosocial helping were weak. We discuss the value of OSPHI as an important construct that reflects the psychological state of “being fully there” at work and predicts subsequent employee work outcomes.

国家公园建设背景下的公益型保护地研究进展

当前我国自然保护地体系改革正处于关键时期,公益型保护地是一种利用社会公益力量,由政府监督、民间管理并协调保护与发展的新型保护地模式。该模式注重社会公益力量在自然保护地建设中的作用,能够补充已有保护地资金、技术和人力的不足,填补了我国目前保护地体系的空缺。本文论述了国家公园建设背景下的公益保护地的内涵,分析了当前公益保护地的特征,讨论了国内外公益型保护地的运营管理机制,包括土地权利的获得、基于协议保护机制的保护地运营、特许经营在保护地的实施和社区保护模式的成功经验。今后我国公益型保护地的建设应鼓励公益组织与民间力量参与,在管理理念上应坚持保护第一和公益性,促进管理体制转变和科学划定界限,并完善公益组织参与保护地建设的激励和监督机制。     

CANON生物膜载体储存及活性恢复研究

采用不同活性恢复手段研究了短期低温（20d,15℃）储存及常温（25℃）低负荷运行后,CANON-MBBR反应器的活性恢复效果.结果显示,CANON悬浮载体经短期低温储存后,通过先恢复温度后缓慢提高进水负荷的方式可使其TN去除负荷恢复率达到102%.若在温度未恢复的基础上直接将进水负荷提升至原水平运行,CANON悬浮载体生物膜将无法维持正常的EPS含量而易发生脱膜现象,致使TN去除负荷恢复率仅为84%.另外,系统有一定基质浓度的基础上,经过25d常温（25℃）低负荷SBR运行后,通过同样的恢复手段可使TN去除负荷恢复率达到96%.通过微生物菌群分析,确定CANON-MBBR系统中功能微生物优势菌属分别为Nitrosomonas和Candidatus Kuenenia,采取合适的恢复手段使系统进入稳定运行阶段后,两者丰度均可分别达到11%以上及27%以上,且悬浮载体脱膜并未对微生物组成造成明显影响.

Railway safety climate: a study on organizational development

The safety climate of an organization is considered a leading indicator of potential risk for railway organizations. This study adopts the perceptual measurement–individual attribute approach to investigate the safety climate of a railway organization. The railway safety climate attributes are evaluated from the perspective of railway system staff. We identify four safety climate dimensions from exploratory factor analysis, namely safety communication, safety training, safety management and subjectively evaluated safety performance. Analytical results indicate that the safety climate differs at vertical and horizontal organizational levels. This study contributes to the literature by providing empirical evidence of the multilevel safety climate in a railway organization, presents possible causes of the differences under various cultural contexts and differentiates between safety climate scales for diverse workgroups within the railway organization. This information can be used to improve the safety sustainability of railway organizations and to conduct safety supervisions for the government.
