A three-dimensional trajectory tracking control policy of a mid-water trawl net is presented. For the entire trawl system, a four material points simplified model is established, which can embody the horizontal expansion effect of the trawl mouth. Based on the backstepping method, a output-tracked controller ...
The accumulation and impacts in the ocean of marine debris generated by anthropogenic activities and aggravated by natural disasters are of growing concern, yet our existing data collection systems are rudimentary and cannot answer even fundamental questions. This is partly due to the diversity of the ...
This study uses freshwater fish of Taiwan as an example to explore people's preferences regarding conservation of endangered animal species and restoration policies, as well as a measurement of the value they are willingness to pay. This study employs the contingent valuation method (CVM) to construct ...
Aiming at the environmental characteristic and the tuna fishery in the open South China Sea (SCS), we put forward a tuna fishing ground forecasting information service system designing thought for the open SCS with its actual requirement. The primary modules and their functions were described and the ...
A key challenge in contemporary ecology and conservation is the accurate tracking of the spatial distribution of various human impacts, such as fishing. While coastal fisheries in national waters are closely monitored in some countries, existing maps of fishing effort elsewhere are fraught with uncertainty, ...
Glucocorticoids (GCs) in utero influence embryonic development with consequent programmed effects on adult physiology and pathophysiology and altered susceptibility to cardiovascular disease. However, in viviparous species, studies of these processes are compromised by secondary maternal influences. ...
This article examines lake drying and livelihood dynamics in the context of multiple stressors through a case study of the “Small Lake Chad” in the Republic of Chad. Livelihoods research in regions experiencing persistent lake water fluctuations has largely focused on the well-being and security of ...
Nearly half of the malnourished population of the world lives in South Asia, and agriculture is the main source of livelihood of the people in this region. Many review exercises have analysed the available evidences to understand the ways in which agriculture can be leveraged to enhance nutritional ...
Abstract In 2011, the zebrafish research facility at the University of Oregon experienced an outbreak of Mycobacterium marinum that affected both research fish and facility staff. A thorough review of risks to personnel, the zebrafish veterinary care program, and zebrafish husbandry procedures at the ...
Abstract In the past two decades, zebrafish (Danio rerio)-based research has contributed to significant scientific advances. Still, husbandry and health programs did not evolve at the same pace, as evidenced by the absence of general guidelines. Health monitoring is essential to animal welfare, to ...
Abstract We have established a European Zebrafish Resource Center (EZRC) at the KIT. This center not only maintains and distributes a large number of existing mutant and transgenic zebrafish lines but also gives zebrafish researchers access to screening services and technologies such as imaging and ...
Abstract Considering the numbers of zebrafish held in the laboratories, it is relevant to develop some tools to monitor the health of the animals, as well as their biotope. Environmental samples can be used to detect aquatic pathogens. Comprehensive health monitoring would thus seek pathogens in three ...
Colour and pattern are key traits with important roles in camouflage, warning and attraction. Ideally, in order to begin to understand the evolution and ecology of colour in nature, it is important to identify and, where possible, fully characterise pigments using biochemical methods. The phylum Mollusca ...
The continuous monitoring of pollution level in urban areas is important for a smart city. There are several parameters changes that indicate the pollution: dust particle density in the air, humidity, light intensity, and the level of sound noise. A technology that can be developed for an integrated ...
The motivation for a satellite mission to measure surface winds (stress) and surface currents is described. The mission concept is explained, and a successful example is shown based on simulated satellite sampling of the output a high-resolution ocean model with and without anticipated measurement n...
A large number of world's population lives within coastal areas. These environmentally sensitive zones bear both natural pressures such as erosion, accretion and natural disasters and anthropogenic impacts such as urban growth, resource exploration and pollution. The decay of coastal ecosystem has an ...
Aquaculture has an important potential in the alleviation of food shortfalls and poverty in many countries. The effective practice of aquaculture is based on several requirements, among which the location of appropriate sites and information which allows merging with activities of local populations ...
With the background of global change, wetland has great sensitivity and vulnerability. In order to investigate the spatial characteristics and heterogeneity in the pattern and dynamic of natural and constructed wetlands, the wetland ecosystem pattern in 1990, 2000, 2013 were rebuild based on satellite ...
In this paper, the data source are GF-1 WFV image and Radarsat-2 SAR image covering the Yellow River Estuary wetland eastern area. The paper first uses Gram-Schmidt algorithm for fusing GF-1 image and different polarimetric mode SAR images, and then uses the method of SVM for supervised classification. ...
The TanDEM-X constellation is served by two X-band SAR satellites, which fly in close orbit formation acting as a large and flexible single-pass radar interferometer. This paper investigates the potentials for monitoring sea ice in the Bohai Sea with the unique constellation. Our results show that the ...
