Integrative Conservation, EarlyView.This research reveals the functional stability of mixed species foraging flocks (MSF) and their foraging height change with different taxonomic differences along the elevational gradient at Knuckles Montane Reserve, Sri Lanka. This offers new insights into how MSFs sustain with the elevational gradients supporting the altitudinal shifting species ...

Rare Metals, EarlyView.ABSTRACT The poor Zn chemistry of Zn metal anode and sluggish reaction kinetics of cathodes at high mass loadings are two crucial issues for hindering the application of aqueous Zn‐ion batteries (AZIBs). Herein, the hierarchical porous N‐doped carbon fibers (HPNCFs) were proposed to simultaneously optimize the reversibility of Zn plating/stripping of ...

Conservation Biology, EarlyView.Abstract Measuring area‐based conservation outcomes in tropical forests is challenging due to cryptic human disturbances (e.g., hunting). As a result, comparative studies of management strategies providing quantitative outcomes remain scarce, especially in the Neotropics.

Hobbyist preferences for pet freshwater turtles
Conservation Biology, EarlyView.Abstract The burgeoning pet trade is a primary threat to wild freshwater turtles worldwide. Although the risks from commercial exploitation of turtles have been discussed widely, there is little empirical research on preferences for pet turtles from a hobbyists’ perspective.

Effects of parachute science on local research capacity 降落伞科学对当地研究能力的影响
Conservation Biology, EarlyView.Abstract Strengthening research capacity is essential to address the global biodiversity crisis. Yet, parachute science often undermines this goal, and its prevalence, costs, and benefits are unclear. We analyzed 13,502 publications on primate research that we extracted from Scopus (1960–2022) to evaluate the effects of parachute science on local ...

Study and Realize the Protection Device Base on the FREESCALE 56800 Family Dsp [PDF]
, 2010 电力系统自动化是自动化领域的一个主要分支，而微机型继电保护测控装置是电力系统中电气元件发生故障或不正常运行状态时，动作于断路器跳闸或发出信号的一种自动装置，是电力系统自动化的重要组成部分。现有微机保护装置大多基于传统的单片机，无法满足电力系统终端用户的高速度、高精度的特殊需求，随着电子技术发展，采用更先进的元件和更先进的方法来研究设计出能符合用户需求的产品，是行业的发展方向。本课题研究了国内外在继电保护方面先进的技术经验及最新的DSP技术的应用，提出了一种基于DSP内核的 ...

Differences in characteristics between naturalized threatened plants and other threatened plants
Conservation Biology, EarlyView.Abstract Many non‐native plant species introduced by humans have become naturalized. At the same time many species are threatened in their native range. However, the number of plant species threatened in their native range that are naturalized elsewhere remains unknown.

Representation of obligate groundwater‐dwelling copepod diversity in European protected areas
Conservation Biology, EarlyView.Abstract Groundwaters sustain diverse surface ecosystems and are populated by metazoan species, mostly invertebrates, that provide fundamental ecological functions and are often of prominent conservation value due to narrow endemism and high phylogenetic rarity.
