Finding floral and faunal species richness optima among active fire regimes
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.

Design and Implementation of a Central Industrial Apparatus Storehouse Information Management System in Power Supply Industry [PDF]
在当前供电行业蓬勃发展的背景下,供电公司的配网带电作业也变得越来越频繁。更重要的是,由于配合带电作业的绝缘工器具种类繁多,往往需要专门的库房和专职人员进行管理;然而传统的工器具库房管理已经赶不上行业的发展变化,因此需要建立一个信息化的工器具库房管理系统。 工器具库房管理系统的主要应用场景借助了RFID技术,在此基础上结合J2EE的技术优势,实现了工器具库房信息的采集、侦听、监控等功能。系统于先进的网络互连,并在此基础上应用了J2EE体系架构,并利用XML语言进行编程。在系统的三层软件架构中 ...

This paper proposes a ‘relaxed’ point‐count survey method to enhance accessibility and expand geographic coverage by easing these constraints. Surveys can be conducted in diverse locations, including urban areas and travel routes, within flexible timeframes (e.g., 6 h after sunrise or during the evening) and with adaptable spacing between survey points,
