Bulletin of Chinese Academy of Sciences (Chinese Version)
Between 2000 and 2020, global wildfires contributed to approximately 7.32 billion metric tons of carbon dioxide (CO2) emissions, accounting for about 18.5% of CO2 emissions released from fossil fuels. Forest fires alone contributed to around 20% of these wildfire emissions, approximately 1.5 billion metric tons of CO2. Due to climate change and human activities, carbon emissions from forest fires are on the rise. For example, the 2023 Canadian fires have emitted 1.268 billion metric tons of CO2 up to August 29th. Despite the simultaneous increase in forest area and volume, the frequency and extent of forest fires have significantly decreased …

Bulletin of Chinese Academy of Sciences (Chinese Version)
Oasisization is an external manifestation of the temporal and spatial evolution of oasis in arid areas, and the regional water carrying capacity is the key to restricting oasis agriculture and ecological protection in arid areas. The Hexi Corridor is not only an important passage from the east to the west in China, but also an important carrier of regional development; it is not only an important ecological barrier in Northwest China, but also a typical irrigated agricultural area. After more than 60 years of construction, the Hexi Corridor has made remarkable achievements in social progress, traffic conditions, ecological construction and …

Developing Ecological Security Pattern For Coastal Wetlands Based On “Three-Line Integration” Spatial Strategy, Xiaowen Li, Liehui Zhi, Tiantian Ma, Zengli Liu, Baoshan Cui, Dongdong Shao, Yu Cao, Yonglin Mu
Bulletin of Chinese Academy of Sciences (Chinese Version)
Coastal wetlands function as key socioeconomic resources as well as ecological barriers for sustainable development in coastal regions. Although previous research and practices indicate that restoration of degraded wetlands needs combination with intact natural wetlands to achieve best integrated ecosystem services, this kind of integration is still lacking both in research and practice. In the past decades, increased land reclamation coupling with climate change (e.g. sea level rise) have led considerable coastal squeeze effects and intensified degradation and loss in coastal wetlands along Chinese coastline, restoration of damaged coastal wetlands is therefore urgently needed to enhance the overall ecological functions …

Nets are used across a wide variety of food production landscapes to control avian pests typically resulting in deaths of entangled birds. However, the impact of nets on bird populations is a human–wildlife conflict that remains mostly unquantified. Here, we examined the scale of netting in the central plains of Thailand, a region dominated by ricefields, among which aquaculture ponds are increasingly interspersed. Nets/exclusion types, number of individual birds and species caught were recorded on 1312 road-survey transects (2-km length × 0.4-km width). We also interviewed 104 local farmers. The transect sampling took place in late- September 2020, and from …

Changes in the timing of extreme precipitation have important ramifications for public safety and storm water management, but it has not received much attention in relation to flooding. This study analyzed the changes in the timing of extreme precipitation in the Poyang Lake basin and projected its future changes for the period 2020–2099. The study also quantified the influences of changes in the timing of peak flows on lake floods based on a hydrodynamic model. The results showed that peak rainfall in the Poyang Lake basin had occurred on later dates during the period 1960–2012, and it is this change …

United States Department of Agriculture Wildlife Services: Staff Publications
Animals communicate with potential mates using species-specific signals, and pheromones are powerful sexual signals that modify conspecific behavior to facilitate mate location. Among the vertebrates, snakes are especially adept in mate searching via chemical trailing, which is particularly relevant given that many snake species are invasive outside their native ranges. Chemical signals used in mate choice are, thus, potentially valuable tools for management of invasive snake species. The Burmese python (Python bivittatus) is an invasive snake in the Florida Everglades where it is negatively impacting native fauna. In this study, we sought to: (i) determine if males can follow conspecific …
Drought Perceptions And Management Techniques For Outdoor Recreation In The Great Plains, Lauren Uhlig
Drought Perceptions And Management Techniques For Outdoor Recreation In The Great Plains, Lauren Uhlig
Department of Environmental Studies: Undergraduate Student Theses
Outdoor recreation generates nearly $887 billion dollars in annual consumer spending and improves quality of life by promoting physical activity (Oftedal & Schneider, 2013; Outdoor Industry Association, 2017b). This industry relies heavily on the environment and these societal benefits are at risk as climate fluctuates. Drought is a regular component of the Great Plains climate (Miao et al., 2007) and can alter the landscape, changing the demand for outdoor recreation and creating challenges for managing recreation opportunities (USDA, 2017). This thesis explores the influence of drought on individual’s willingness to participate in outdoor recreation, the variation in that influence across …

Daugherty Water for Food Global Institute: Faculty Publications
Estimation of turbulent heat fluxes via variational data assimilation (VDA) approaches has been the subject of several studies. The VDA approaches need an adjoint model that is difficult to derive. In this study, remotely sensed land surface temperature (LST) data from the Moderate Resolution Imaging Spectroradiometer (MODIS) are assimilated into the heat diffusion equation within an ensemble Kalman smoother (EnKS) approach to estimate turbulent heat fluxes. The EnKS approach is tested in the Heihe River Basin (HRB) in northwest China. The results show that the EnKS approach can estimate turbulent heat fluxes by assimilating low temporal resolution LST data from …

The Effects Of Multilingualism Of Executive Function, Isabella Catalano
Department of Environmental Studies: Undergraduate Student Theses
In today's world, monolingualism is in the minority (Alonso et al., 2017); however, there is still a lack of understanding about the potential effects of being bi- or multilingual, and whether there is an effect of bilingualism in executive function is debated, given multiple contradictory studies (Paap et al., 2015). This study aims to more closely examine whether the number of languages spoken is related to executive function. In this study, sixty-three participants (mean age = 19.9 years, males = 10) completed the Stroop and flanker tasks, measures of inhibitory control, as well as the Language Experience and Proficiency Questionnaire, …

A modern challenge for conservation biology is to assess the consequences of policies that adhere to assumptions of stationarity (e.g., historic norms) in an era of global environmental change. Such policies may result in unexpected and surprising levels of mitigation given future climate-change trajectories, especially as agriculture looks to protected areas to buffer against production losses during periods of environmental extremes. We assessed the potential impact of climate-change scenarios on the rates at which grasslands enrolled in the Conservation Reserve Program (CRP) are authorized for emergency harvesting (i.e., biomass removal) for agricultural use, which can occur when precipitation for the …

Well-managed grasslands provide numerous ecosystem services. Ranchers who employ sustainable grazing practices limit grassland conversion and conserve critical habitats. This phenomenological study explored the grassland management decisions of progressive ranchers in Nebraska. Each individual interviewed for this study is proactive about the state of their grasslands, whether they are motivated by financial or conservation factors. Throughout the evolution of their businesses, these ranchers have taken steps to improve their management techniques and continue to employ new strategies while planning for the long-term productivity of their grasslands. For policy makers and educators seeking to improve grassland management decisions, demonstrating new methods …
