Prioritizing bat roosts for conservation with a global multicriteria bat roost priority index based on community science

open access: yesConservation Biology, EarlyView.
Abstract Prioritization in conservation is crucial for the development of efficient and effective decision‐making policies. For many decades, the importance of some species and their habitats has been assessed and applied in conservation legislation, but bats and their diurnal roosts have ofbeen overlooked.

Contribution of microcosm experiments to conservation science

open access: yesConservation Biology, Volume 40, Issue 1, February 2026.
Abstract Microcosms, or miniature experimental systems, have been used to develop models and theories in ecology. However, their contribution to conservation science is unclear. We explored the application, design, and impact of microcosms in conservation science from 469 systematically identified articles published from 1986 to 2023.

Research of Total Alkalinity Online Monitoring and Control System [PDF]

open access: yes, 2016
总碱度是锅炉水处理过程中的一项重要指标,为保证锅炉的安全运行,需要对锅炉水总碱度进行精确测量并随时了解锅炉水中碱度的情况。目前,锅炉水总碱度的监测一般采用传统滴定的方法,即人工移取水样后再进行滴定的方式,但该方法不仅劳动强度大,还具有错误率较高、效率低下、管理混乱等问题,对安全生产也会产生一定的影响。针对以上问题,本文研究了一种对锅炉水总碱度进行自动测算、数据传输以及监控的总碱度在线监测和控制系统。 为了满足锅炉水总碱度自动测算和远程监测的需求,本文建立了锅炉水总碱度在线监测和控制系统 ...

Extent of threats to marine fish from the online aquarium trade in the United States

open access: yesConservation Biology, Volume 40, Issue 1, February 2026.
The global marine aquarium hobby is a multibillion‐dollar industry, largely driven by demand from the United States. Much of this trade occurs online. We web scraped 4 major US‐based e‐commerce platforms selling marine aquarium fish to determine the retail price and source (wild capture, aquaculture, or both) of 13 families of ray‐finned marine fish ...

Design and Implementation of Online Environmental Monitoring System Based on B/S [PDF]

open access: yes, 2015
随着社会经济的快速发展和人类生活水平的逐步改善,人类在创造所需物质文明的同时,环境污染和生态破坏也在日益加重。传统的环境监测系统缺乏长时间的、具有代表性的监测数据,无法适应长期有效管理机制的需求,所以需要一种远程的在线环境监测系统。随着计算机网络技术的快速发展,建立一套自动化的环境在线自动监测系统,是环境监测发展的一个必然趋势。它能及时反映环境质量,实时跟踪污染源的变化,能准确预测各种突发环境事件。 针对传统监测方法的缺陷,本文基于B/S架构进行在线环境监测,利用GIS、ArcGISServer ...

Design and Implementation of Energy Management System for Residential District [PDF]

open access: yes, 2016
近些年来,为了实现对住宅小区内能源的智能化控制,住宅小区能源管理系统已经成为研究的热点问题。国内外的部分大型公司已经提出了它们的相关设计产品,并在部分地方进行试点。然而,在我国小区智能化进程中,由于受到大部分城区能源网络比较老化的限制,全面推广小区智能化遇到了诸如能源网络改造工程大、时间久、成本高等问题。本文是针对我国旧式小区能源网络而提出的一款住宅小区能源管理系统(HEMS),在不需要对现有的能源网络进行大幅度改造的前提下,实现住宅内能源使用的远程管控 ...
