Four challenges to an effective national nature assessment
Conservation Biology, Volume 37, Issue 5, October 2023., 2023 Abstract Comprehensive biodiversity assessments play an essential role in strengthening global and national conservation strategies. The recently announced first U.S. National Nature Assessment (NNA) provides an unparalleled opportunity to comprehensively review status and trends of biodiversity at all levels.

Region‐wide retreats from lower elevations of range‐restricted birds across the Northern Andes
Conservation Biology, Volume 37, Issue 5, October 2023., 2023 Abstract Local studies show upslope shifts in the distribution of tropical birds in response to warming temperatures. Unanswered is whether these upward shifts occur regionally across many species. We considered a nearly 2000‐km length of the Northern Andes, where deforestation, temperature, and extreme weather events have increased during the past ...

World Water Policy, Volume 9, Issue 3, Page 456-480, August 2023., 2023 Abstract Groundwater is a vital resource under threat in island communities. Karainagar, a 22 km2 island, is one of seven islands off the coast of Jaffna in Northern Sri Lanka, with its population of just about 11,000 persons, experiences seasonal water shortage, and salinity in groundwater as twin threats impacting on their lives.

A field experiment characterizing variable detection rates during plant surveys
Conservation Biology, Volume 36, Issue 3, June 2022., 2022 Abstract Surveys aimed at finding threatened and invasive species can be challenging due to individual rarity and low and variable individual detection rates. Detection rate in plant surveys typically varies due to differences among observers, among the individual plants being surveyed (targets), and across background environments.

Using expert knowledge to support Endangered Species Act decision‐making for data‐deficient species
Conservation Biology, Volume 35, Issue 5, Page 1627-1638, October 2021., 2021 Abstract Many questions relevant to conservation decision‐making are characterized by extreme uncertainty due to lack of empirical data and complexity of the underlying ecologic processes, leading to a rapid increase in the use of structured protocols to elicit expert knowledge.

Veterinary Dermatology, Volume 32, Issue 4, Page 331-e92, August 2021., 2021 Background MicroRNAs (miRNA) are short, single‐stranded RNA molecules that regulate gene expression in a post‐transcriptional manner. Their expression is proposed to be tissue‐specific and alterations in miRNA expression have been detected in many diseases. Objective To compare miRNA expression in the skin of healthy Labrador and golden retrievers, and

考虑换流器伪量测建模的交直流混联电网状态估计方法 [PDF]
全球能源互联网, 2022 随着直流源储荷的接入与柔性直流电力电子设备的发展，含多种分布式电源（distributed generation,DG）的交直流混联电网被认为是未来电网的主流架构，这给系统操作带来了更多灵活性，但也加剧了量测数据不足的问题，使得系统状态估计求解更加困难。目前成熟的交流状态估计未计及直流系统状态量和量测量的特征及各类DG出力的不确定性，且通常默认换流器控制方式已知，控制方法未知时的伪量测建模技术有待研究。采用计及电压源换流器（voltage source converter,VSC）损耗的模型 ...

Trends in seabird breeding populations across the Great Barrier Reef
Conservation Biology, Volume 35, Issue 3, Page 846-858, June 2021., 2021 Abstract The Great Barrier Reef is an iconic ecosystem, known globally for its rich marine biodiversity that includes many thousands of tropical breeding seabirds. Despite indications of localized declines in some seabird species from as early as the mid‐1990s, trends in seabird populations across the reef have never been quantified.

Redistributive effects of fiscal policies in Mexico: Corrections for top income measurement problems
Latin American Policy, Volume 12, Issue 1, Page 148-180, May 2021., 2021 Abstract This article assesses the redistributive effects of fiscal instruments in Mexico in 2010–2014, correcting for top‐income measurement problems. Two correction methods are applied—survey‐sample reweighting for households' nonresponse probability and replacing of top incomes using smooth Pareto distributions—to reestimate the effects of pensions,

Zhejiang Daxue xuebao. Lixue ban, 2023 经济发展不均衡是区域经济的常态，适度的区域经济差异有利于发挥地区比较优势。近年来，区域经济差异研究大多集中在中部沿海、长三角、珠三角等发达地区，对广西壮族自治区等欠发达地区的研究很少。以广西壮族自治区92个县域为基本研究单元，利用变异系数、泰尔指数和探索性空间数据分析，研究2005—2020年县域经济集聚差异的时空演变格局，并通过构建空间杜宾模型，探究差异的形成原因。结果表明：（1）县域经济的绝对差异逐渐增大，相对差异略有缩小，区域内差异一直大于区域间差异；（2）大部分县域经济发展处于孤立状态 ...
