Assessing freshwater fish sensitivity to different sources of perturbation in a Mediterranean basin

Abstract –  The accuracy of bioassessment programmes is highly limited by the precision of the systems used to derive sensitivity–tolerance values for the organisms used as indicators. We provide quantitative support to the objective evaluation of freshwater fish species sensitivity to different sources of disturbance, accounting for co-variation issues not only between perturbations and natural gradients (especially river size), but also between different perturbations. With this aim, we performed two different principal component analyses: (i) on a general environmental matrix to obtain a perturbation gradient independent of river size effects and (ii) on human impairment-related variables to extract independent synthetic perturbation gradients. Then, we checked each species responses to those gradients to assess their sensitivity–tolerance through an available-used chi-squared analysis in the first approach and through a t -test/ ancova analysis in the second one. In this way, we obtained sensitivity–tolerance which could be included in future bioassessment tools, enabling effective evaluations.     

试论科学发展观对林业发展的重大意义

党中央提出的科学发展观对林业发展有着极为重要的意义。文章从重视人的主体性、森林经营利用多元化、森林经营管理开放性和森林永续利用等四个方面,分别阐述了以人为本,全面、协调、可持续发展对林业的指导意义。     

Socio-economic significance of reed forests in a rural community: A case study from the greater Sylhet Region of Bangladesh

The reed forests that are the subject of this study are scattered over five thanas of the Sunamganj and Sylhet Districts of the Sylhet Division of Bangladesh. Their total area is 23,590 ha and they have great ecological, economic, commercial and socio-economic importance due to the diversified resources they supply. However, the forests are commonly encroached on by local people who are perceived to be seriously depleting the resource. This paper deals with the socio-economic status of the people residing near these reed forests, and examines their dependency on the resources provided by the reed forests. A socio-economic survey, participatory rural appraisal and interviews were used to obtain baseline data of the reed forest resource and the local communities. The study reveals that the communities in the study region have higher income than other areas of Bangladesh. Most survey respondents have other occupations in addition to farming. The literacy rate is 28.8%. Among the illiterate, 68% engage in collecting reeds. Although the Forest Department has a management plan for sustainable use of the reed forests, encroachers receive backing from political leaders and local elites, so their eviction is difficult. In order to achieve long-term productivity and sustainability from the reed forests, this study recommends a strategy of developing an integrated joint management plan between the Forest Department and the local people.     

Traditional homegardens of Kerala: a sustainable human ecosystem

An analogue approach to analysing the traditional homegardens of Keralavis-à-vis natural climax ecosystems is adopted. The traditional homegarden is apparently a climax ecosystem, where ecological succession is consciously manipulated by human beings. High intensity of vertical and horizontal space use, the highly dynamic chronological structure and the capacity to perform essential ecological processes make this ecosystem relatively sustainable. Homegardens in Kerala effectively serve as human ecosystems with their low input demand, staggered supply of outputs, and enhancement of habitat quality. However, recent trends in agrarian structure and the high market orientation exert pressures on the homegarden, and its sustainability as a human ecosystem is in question.This joint paper is based on part of the research conducted by Darley Jose for the degree of M.Sc. (Natural Resource Management) at the Agricultural University of Norway under the guidance of N. Shanmugaratnam.     

福建寿宁县兽害猖獗的成因及对策初探

1998～2006年,以寿宁县为调查对象,运用机械抽样法调查样带69条,运用访问调查法调查猎户农户100余户,运用点面互换法调查全县范围内农田作物受害程度。结果表明,全县近半数的村,15%的耕地存在兽害,99%的兽害及其损失源于野猪的活动。分析表明,兽害的成因有种群爆发、物种灭绝和生态系统衰败诸多因素,而人为干扰是各种现象的起因。最后提出治理山区兽害的对策,尤其应加强生态系统恢复和自然保护区建设。     

Comparative analysis of MAPK and PI3K/AKT pathway activation and inhibition in human and canine melanoma

The lack of advanced animal models of human cancers is considered a barrier to developing effective therapeutics. Canine and human melanomas are histologically disparate but show similar disease progression and response to therapies. The purpose of these studies was to compare human and canine melanoma tumours and cell lines regarding MAPK and PI3K/AKT signalling dysregulation, and response to select molecularly targeted agents. Pathway activation was investigated via microarray and mutational analysis. Growth inhibition and cell cycle effects were assessed for pathway inhibitors AZD6244 (MAPK) and rapamycin (PI3K/AKT) in human and canine melanoma cells. Human and canine melanoma share similar differential gene expression patterns within the MAPK and PI3K/AKT pathways. Constitutive pathway activation and similar sensitivity to AZD6244 and rapamycin was observed in human and canine cells. These results show that human and canine melanoma share activation and sensitivity to inhibition of cancer‐related signalling pathways despite differences in activating mutations.     

Recurrent Temporary Paralysis Reported After Human Rabies Post‐Exposure Prophylaxis

Adverse events can occur after rabies post‐exposure prophylaxis (PEP), and linkage to causality is often difficult to determine. We report a case of recurrent temporary paralysis that began immediately after the initiation of rabies PEP in a man exposed to a bat. The recurrent temporary paralysis first occurred in the patient after his initial dose and then again after day 3 of his rabies PEP. The PEP was terminated prior to a serologic response. The patient continued to experience numerous discrete episodes of temporary paralysis for over two years.
