Haiyang yu huzhao棘皮动物是主要的后口动物之一，在进化上具有重要意义，海参、海胆等作为我国重要水产养殖物种，具有重要的经济价值和营养价值。免疫对动物生长、发育、繁殖具有重要的作用，微生物参与宿主免疫调节，其作用至关重要。繁殖期是动物重要的生活史阶段，但动物在繁殖期会出现免疫力降低等系列生理功能下降的现象。笔者主要综述了棘皮动物非特异性免疫类型、参与棘皮动物免疫的微生物类群、棘皮动物繁殖期免疫调控与微生物协同作用的研究进展，并展望了棘皮动物免疫应答的研究方向与应用前景 ...

The enigmatic life history of the bamboo explained as a strategy to arrest succession
Ecological Monographs, Volume 94, Issue 4, November 2024.Abstract Bamboos are perennial woody grasses that display an enigmatic mix of traits. Bamboo is highly shade intolerant like early‐successional trees. Without secondary xylem, bamboos cannot continue to grow once they reach a maximum height or replace xylem damaged by hydraulic stress and must instead replace each stem after a few years using ...

Financial speculation meets cultural heritage in China's wildlife markets
Conservation Biology, Volume 38, Issue 5, October 2024.Abstract Environmental regulations restricting the use of a natural resource or species often have unintended consequences. One example is prohibitions on the international trade in culturally important endangered wildlife. Trade restrictions may artificially increase scarcity and, consequently, value.

野生动物学报, 2007 采用扫描取样法对秦皇岛野生动物园40只笼养绿孔雀繁殖期的行为进行了为期58d,325h的观察,结果显示繁殖期各行为所占的比例分别为休息31.31%、取食22.03%、理羽16.37%、游走15.93%、警戒9.79%和繁殖4.59%。方差分析和μ检验表明:天气状况对笼养绿孔雀的休息、取食、理羽和游走行为的时间分配的影响明显,但对繁殖和警戒行为影响不大。
