"生态学马克思主义"生态危机理论深刻揭示了资本主义制度及生产方式与全球性生态危机的必然性联系,指出生态危机的资本主义制度根源,将解决生态危机与社会主义联系起来,主张建立生态社会主义社会,并就如何实现生态社会主义提出了一系列方案.这对于我们正在进行的社会主义现代化建设具有多方面的重要启示.

1 Introduction
Phenotype variation within populations both provides the raw material for and is the product of evolutionary change. An individual's phenotype, defined as the amalgamation of morphology, physiology, and behavior, is highly complex. It has been common to try to isolate each of these aspects of phenotype rather than directly examine their integration. For example, despite the demonstrated importance of single aspects of phenotype for acquiring mates it is well known that signal traits are not evaluated in isolation, but rather in conjunction with associated behaviors, and sometimes with other signal traits (Moiler and Pomiankowski, 1993; Candolin, 2003;

随着微生态学理论研究的不断深入,微生态制剂发展的速度也日益加快.我国微生态制剂的研究起步较晚,尽管近十几年在动物保健方面取得了长足的进步,但该行业整体还处于发展期.为推动我国微生态制剂行业的发展,开拓微生态制剂的应用领域,完善微生态制剂加工工艺,搭建产学研的交流平台,展示我国微生态制剂行业发展成果,《饲料工业》杂志2012年将编辑出版《微生态制剂研究与应用》增刊.

为了应对智能手机所面临的信息安全威胁,提出一种基于行为生物特征的手势用户认证方案。实时采集手机内置三轴加速度传感器的数据,经有效手势端点检测得到认证数据,在信号去噪环节提出了一种结合小波包分解与互信息熵的新方法,最终由改进的动态时间规整算法进行手势信号序列相似性度量,从而得出认证结论。实验结果表明,当他人模仿手势错误接受率趋近0%时,本人认证手势错误拒绝率维持在7%左右,认证精度良好,同时算法时间复杂度低,可以实时有效对智能手机的持有者进行身份识别。

Most seabird species display colonial behavior during the breeding period which implies that food resources around breeding sites can easily go depleted. Seabirds need to both reach profitable areas, which can be located far from the colony, and return to the colony regularly. In this context, flexibility in movement behavior may be crucial for breeding success. During chick-rearing, Procellariformes species can alternate short trips lasting 1-4 days for chick provisioning with longer trips for self-provisioning in what has been called a dual-foraging strategy. We analyzed foraging trips from 136 Scopoli's shearwaters from three Mediterranean colonies tracked with GPS during 6 chick-rearing seasons to assess whether the adoption of a dual fo- raging strategy depends on the quality of habitat surrounding the colony. We found a marked dual-foraging strategy only in birds from the Linosa colony which was the largest colony in terms of breeding pairs and was characterized by having a lower marine habitat quality. Birds from this colony performed foraging trips that extended up to 369 km from the nest and lasted more than 10 days. In general, the decision to perform long lasting trips was triggered by lower values of primary production and higher offspring weight. Contrary to expectation, the decision to feed far from the colony was not related to the parents' weight. At the same time, despite the higher productivity offered by distant areas, the higher proportion of long trips performed by birds breeding in poor areas was not sufficient to maintain the same body mass as the ones breeding in richer areas [Current Zoology 60 (5): 622-630, 2014].

以综述大量创新生态系统研究文献为基础,试图理顺不同层次相关研究的区别和联系;紧扣创新系统理论强调的"主体之间相互依赖"和生态学强调的"主体与环境的相互作用",将创新生态系统的各类组成要素统一到一个"中心-外围"的结构分析框架之中;通过分析微观、中观和宏观三个层次创新主体(中心)和环境(外围)范畴的变化,揭示出不同层次的内涵、结构和行为,以及各层次之间的相互作用.以此基础上为其理论研究和实践发展提出三点启示.
