野生动物学报, 2021 雉鸡的亚种众多，在其表型与遗传上具有地理变异。雉鸡的一些亚种适应于不同的地理条件（例如：寒带、热带、干旱区、高原）形成了独特的群体形态特征，尤其体现在雄性个体的羽色图案上。羽色图案的复杂性给雉鸡亚种的人工鉴定带来了挑战，为此，本研究探索应用图像识别技术对雉鸡亚种进行识别。对3种识别算法：K近邻分类算法，概率神经网路和符号分类器进行了比较。通过序列前向选择法、序列后向选择法、序列浮动前向选择法和序列浮动后向选择法等算法对差异纹理特征进行提取和比较。本研究对25个雉鸡亚种的高质量博物馆标本的图片进行分析验证。

Mating system, brood parasitism and extra-pair behaviour in the Chinese egret (Egretta eulophotes) basing on the microsatellite technology [PDF]
, 2015 动物的婚配制度影响着个体的繁殖成功率，直接关系到群体的遗传多样性和种群动态的发展变化，是保护遗传学和生态学领域中非常重要的研究内容。已有学者野外观察到黄嘴白鹭（Egrettaeulophotes）存在婚外交配（EPC）行为，然而，有关黄嘴白鹭的婚配制度、EPC的产生机制以及其是否会导致婚外父权（EPP）现象还未清楚。此外，许多集群繁殖的鸟类都存在种内巢寄生（CBP）现象，而关于黄嘴白鹭巢寄生行为的研究也尚未开展。因此，本研究围绕黄嘴白鹭的婚配制度问题，主要开展以下几方面研究： （1）对3种非损伤性样品 ...

Defining and identifying relevant stakeholders to advance effective conservation
Conservation Biology, EarlyView.The challenge of defining stakeholders in environmental science and an approach for refining existing definitions. Abstract Stakeholder is a contested term that has spawned a multitude of ad hoc definitions. The ambiguity of these definitions has oftentimes impeded transdisciplinary research in environmental governance and conservation science because ...

Dolphins whistle contour automatic extraction and recovery [PDF]
, 2015 海豚是一种高智商的水生哺乳动物，它们使用自己独特的“语言”——哨声来进行互相交流。要想理解海豚的语言，就必须要对海豚哨声进行分析研究。当前对海豚哨声的分析研究大多是基于哨声语谱图进行的，但语谱图中哨声轮廓与背景噪声混合在一起，不仅导致目前对哨声的分割、提取等预处理都是用人工方式进行，同时也给后续的实验造增加了难度。如果对语谱图中的哨声轮廓进行去噪、特征提取和修复等自动化预处理，就能实时进行海豚哨声与背景噪声的分离，获得一个完整的海豚哨声轮廓。这不仅节约了人工提取花费的时间，也有利于海豚哨声的个体识别 ...

Structured machine learning modeling to support conservation of deep‐sea benthic biodiversity
Conservation Biology, EarlyView.Abstract Biodiversity monitoring programs need to deliver accurate, timely, and actionable predictions. To establish a predictive monitoring program for deep‐sea benthos of the Santos Basin, Brazil, we developed a two‐stage structured model that allowed comparison of biodiversity predictions obtained from environmental simulations (2M‐Sim).
