Coastal marine fish populations are in decline due to overfishing, habitat destruction, climate change and invasive species. Seasonal monitoring is important for detecting temporal changes in the composition of fish communities, but current monitoring is often non-existent or limited to annual or semi-annual surveys. In the present study, we investigate the potential of using environmental DNA (eDNA)...
The haptic interface plays important role in remote robot applications since it helps people to feel the real condition to make the control accurate. However, the uncertain time delay in the remote communication introduces issues for critical real time applications, which should be compensated to obtain accurate control. In this paper, the model is proposed first and its stability is studied, second...
The extraction of weak signals from noisy backgrounds is an important part of the modern information theory. Traditional methods based on linear systems such as filtering have limitation in such applications while Chaos theory has more advantage, which becomes an important research direction. In this paper, the nonlinear chaotic Duffing oscillator is studied and simulated for its phase trajectory,...
AimTo compile an inventory of freshwater fish species in China, and to investigate these data to determine spatial patterns in species richness, endemism and threatened species for the purpose of facilitating conservation.
LocationChina
MethodsLiterature, databases and fish collections were examined to create an inventory database of freshwater fishes of China. This list was analysed to determine...
