Zhejiang Daxue xuebao. Lixue ban, 2006 视差估计与补偿是立体视频图像压缩编码中的关键技术.本文分析了立体摄像系统视差分布的约束条件（外极线约束、方向性约束等）和视差矢量的相关性（帧内视差矢量的空域相关性和帧间视差矢量的时域相关性），并结合H. 264标准中的多种块选择模式之间的相关性，提出了基于H. 264的立体视频编码的视差估计快速算法.实验结果表明，提出的快速算法能有效地降低视差估计的计算复杂度.

Evaluating past and future contributions of conservation programs to species recovery
Conservation Biology, EarlyView.Abstract Impact evaluation of conservation actions is a crucial step in global efforts to curb the biodiversity crisis. Through robust impact evaluation, practitioners can assess the effectiveness of conservation strategies and optimize the use of limited resources.

Strengthening community‐based fisheries monitoring programs with Indigenous perspectives
Conservation Biology, EarlyView.Abstract Community‐based monitoring (CBM) programs are increasingly recognized as essential for adaptive environmental stewardship. Yet, the CBM literature often highlights successful cases and privileges evaluations by external experts over those of community members themselves.

Shuitu Baochi Xuebao, 2002 分析了野外实测的1999年种植季节地温资料,将覆膜后地温与不覆膜地温进行对比,分析了种植季节地温特征的变化规律.同时分别研究了800、1400及2000观测的覆膜与不覆膜条件下相邻5 cm土壤耕作层地温的相关性,这3个时间覆膜与覆膜与不覆膜条件下地表0 cm与各耕作层地温之间的相关性,以及同样3个时间同深度覆膜与不覆膜地温的相关性.上述相关关系均可用确定的线性关系表达,拟合的相关系数较高.

How much biotic nativeness matters across human demographic groups
Conservation Biology, EarlyView.Abstract Many central concepts of conservation biology—such as nativeness—are structured by ecological and social factors. However, the social consequences of using these concepts to make conservation decisions remain inadequately understood. Some researchers argue that nativeness, rather than acting as an objective proxy for important ecological ...

Comprehensive framework for assessing and optimizing existing research networks
Conservation Biology, EarlyView.Abstract Conservation, monitoring, and research networks, or collections of ecological research sites unified under a common mission of data collection or a research mission, are essential infrastructure for understanding large landscapes. However, most networks developed opportunistically over decades rather than through systematic design, creating ...

Representation of obligate groundwater‐dwelling copepod diversity in European protected areas
Conservation Biology, EarlyView.Abstract Groundwaters sustain diverse surface ecosystems and are populated by metazoan species, mostly invertebrates, that provide fundamental ecological functions and are often of prominent conservation value due to narrow endemism and high phylogenetic rarity.

Conservation Biology, EarlyView.Abstract In the western United States, conservation practitioners are increasingly working with private landowners to restore habitat for North American beavers (Castor canadensis) and to use nonlethal mitigation techniques when beavers damage crops and infrastructure.

Shuitu Baochi Xuebao, 2017 针对湖北通城花岗岩崩岗区发育的淋溶层（A层）、淀积层（B层）、过渡层(BC层)以及母质层(C层)，采用不同坡度(8.8％，17.6％，26.8％，36.4％，46.6％)和不同流量(0.2，1.0 L/s)相结合的室内放水冲刷试验，分析崩岗各层次土壤的抗冲性指数，初步探讨花岗岩崩岗不同坡度及各层次土壤主要理化性质对抗冲性的影响。结果表明：⑴湖北通城县崩岗土壤A层、B层、BC层以及C层的理化性质存在较大差异。⑵当流量一定时，随着坡度的增大，土壤的抗冲性指数均表现为减小的趋势；当坡度一定时 ...

Effects of political identity activation and inaccurate metaperceptions on attitudes toward wolves
Conservation Biology, EarlyView.Abstract Polarization between groups can undermine durable conservation outcomes. Activating group identities (i.e., an individual's sense of self derived from membership in a group) can exacerbate differences, especially when people hold inaccurate perceptions of their peers and rivals.
