Aim: Yearly summaries of the North American Breeding Bird Survey (BBS) indicate that populations of many North American bird species are in decline. Determining the causes of these declines is the focus of much current research in avian conservation. Forest fragmentation has been linked to declines in populations of many species. In this study, the effects of forest fragmentation and connectivity as well as slope and physiographic features on two migratory bird species are explored. Location: This study area is Virginia, USA. Taxon: The species focused on are Wood Thrush (Hylocichla mus-telina) and the Ovenbird (Seiurus aurocapilla). Methods: We used the Markov Chain Monte Carlo Generalized Linear Mixed Models (MCMCglmm) package with a Poisson distribution and a Bayesian data analysis model with a 95% probability interval. Using the Repeated Measures ANOVA, the independent and treatment variables included time at 3 different levels in 2001, 2006 and 2011; three different forest types—Core, Connected and Fragmented; 8 slope categories and 5 physiographic regions. Results: Results indicate that forest fragmentation has a significant impact on population sizes of Wood Thrush and Ovenbirds in Virginia and that recent changes in Virginia’s landscape have had negative impacts on the populations of these bird species. Specifically, slope characteristics that influence rates of urbanization are cor-related with changes in bird populations. The Coastal Plain region in Virginia contributes significantly to the populations of both the Wood Thrush and Ovenbird currently. Main Conclusions: Core forests areas in Virginia are in decline and this process affects the populations and distributions of Ovenbird and Wood thrush in the
目的:北美繁殖鸟类调查(BBS)的年度摘要表明，许多北美鸟类物种的数量正在下降。确定这些下降的原因是目前鸟类保护研究的重点。森林破碎化与许多物种数量的减少有关。本研究探讨了森林破碎化和连通性、坡度和地形特征对两种候鸟的影响。地点:本研究区域位于美国弗吉尼亚州。分类群:重点研究的种有画眉(Hylocichla musi -telina)和烧鸟(Seiurus aurocapilla)。方法:采用泊松分布的马尔可夫链蒙特卡罗广义线性混合模型(MCMCglmm)包和95%概率区间的贝叶斯数据分析模型。使用重复测量方差分析，自变量和治疗变量包括2001年、2006年和2011年3个不同水平的时间;三种不同的森林类型——核心森林、连通森林和破碎森林;8个坡度类别和5个地理区域。结果:森林破碎化对维吉尼亚州画眉鸟和火炉鸟的种群数量有显著影响，近年来维吉尼亚州景观的变化对画眉鸟和火炉鸟的种群数量产生了负面影响。具体而言，影响城市化率的斜坡特征与鸟类种群的变化相关。目前，弗吉尼亚沿海平原地区对画眉鸟和火炉鸟的种群都有很大的贡献。主要结论:维吉尼亚州的核心林区正在减少，这一过程影响了该地区的炉鸟和画眉鸟的种群和分布

Waste management is one of urgent challenges in the world. In rapidly growing cities of developing countries like Accura, Ghana, waste collection is done without sufficient protection of workers. This situation became worse when the COVID-19 pandemic began to threaten the health and safety of waste collection workers. This paper aims to examine waste management workers’ safety concerns during the COVID-19 pandemic in Ghana. To better understand waste management workers’ safety concerns during the pandemic, we used the questionnaire survey. Our questionnaire survey was conducted among 60 waste management workers in Accra, the capital city of Ghana. The study then discusses how municipal waste management authorities can ensure safety of waste management workers during the pandemic. Our results showed that 58% of the respondents were worried about the COVID-19 pandemic, while 20% were not even sure of the existence of the Covid-19 pandemic. Besides their worry, we also found that about 40% of the respondents had access to face masks/shields at their workplace, and 30% had hand sanitizers. This paper highlights that providing more advanced safety protocols in terms of workers daily operations and safety measures will enable a safe working environment for the workers even in terms of future pandemics.
