Zhejiang Daxue xuebao. Lixue ban, 2017 根据锚点位置固定有否，移动IP协议分为锚点固定的移动性管理协议和分布式移动性管理协议两类，后者允许移动节点在会话开始时动态地选择较近的接入路由器作为锚点，从而可以缩短切换时延并实现近似最优的路由.然而，对于给定的会话，锚点的位置是固定的，在会话持续时间内进行移动节点切换时，切换操作与锚点固定的移动性管理协议相同，存在切换时延长和路由欠优问题.为解决该问题，提出了应用双层指针的分布式移动性管理方案.使用“低层指针”在具有移动性管理功能的接入路由器间建立指向关系以缩短切换时延；使用“高层指针 ...

Finding floral and faunal species richness optima among active fire regimes
Conservation Biology, EarlyView.Abstract Changing fire regimes have important implications for biodiversity and challenge traditional conservation approaches that rely on historical conditions as proxies for ecological integrity. This historical‐centric approach becomes increasingly tenuous under climate change, necessitating direct tests of environmental impacts on biodiversity.

Predictions of southern migration timing in coastal sharks under future ocean warming
Conservation Biology, EarlyView.Abstract Projected redistribution of marine species due to ocean warming may undermine current conservation efforts. Yet, there have been few studies on how ocean warming may alter migration timing. Across 5 years of acoustic telemetry data (2018–2022), we determined environmental drivers of southward migration timing for 6 migratory shark species from

Conservation Biology, EarlyView.Abstract Identifying refugia from emerging threats is vital to ensure the persistence of rare and threatened species, but modeling habitat distribution for these species is challenging and the role of people in refuge management is rarely considered. Myrtle rust is an emerging infectious disease that represents a grave threat to the rare wetland tree ...
