Climate change is affecting the IPLCs (Indigenous Peoples and Local Communities) around the world, including ethnic minorities in China, especially from agriculture, animal husbandry, hunting and gathering, which are their main source of livelihoods. At the same time, IPLCs have rich traditional knowledge related to climate and its disasters, especially in their livelihoods. This review work examines the research about traditional knowledge associated to livelihood in monitoring and adapting to changing climatic conditions in ethnic minorities in China. Authors reviewed the research papers and monographs on the traditional agricultural livelihood of ethnic minorities in China, and divided different agricultural types on the basis of literature review. At the same time, authors focused on reviewing the traditional knowledge formed by ethnic minorities in the agriculture, especially the traditional knowledge related to weather and climate information. In authors’ findings authors realized that ethnic minorities are the practitioners of traditional agricultural practices. Their observation and perception come from real life and may not be “scientific”, but they directly reflect the impact of climate change on local livelihoods and contain wisdom to adapt to climate change. Ethnic minorities not only observe and perceive climate change, but also actively adapt to the impact of climate change on traditional livelihoods. In the process of adaptation, traditional knowledge plays a key role. This paper highlights how traditional knowledge can improve understanding of the influence of climate change on livelihood, and provide ideas to develop an equitable and effective plan to adapt the climate change. For the IPLCs, compared with the externally driven adaption options, they are more willing to take the community-based plan, because such plans will enable them to apply their traditional knowledge according to the geographical location and environment of their areas, so that

The existence of multigenic families in the mevalonate pathway suggests divergent functional roles for pathway components involved in the biosynthesis of plant sterols. Squalene epoxidases （SQEs） are key components of this pathway, and Squalene Epoxidase 1 （SQE1） has been identified as a fundamental enzyme in this biosynthetic step. In the present work, we extended the characterization of the remaining SQE family members, phylogenetically resolving between true SQEs and a subfamily of SQE-like proteins that is exclusive to Brassicaceae. Functional characterization of true SQE family members, Squalene Epox- idase 2 （SQE2） and Squalene Epoxidase 3 （SQE3）, indicates that SQE3, but not SQE2, contributes to the bulk SQE activity in Arabidopsis, with sqe3-1 mutants accumulating squalene and displaying sensitivity to ter- binafine. We genetically demonstrated that SQE3 seems to play a particularly significant role in embryo development. Also, SQE1 and SQE3 both localize in the endoplasmic reticulum, and SQE3 can functionally complement SQEI. Thus, SQE1 and SQE3 seem to be two functionally unequal redundant genes in the pro- motion of plant SQE activity in Arabidopsis.

A comb-shaped chaotic region has been simulated in multiple two-dimensional parameter spaces using the Hindmarsh-Rose （HR） neuron model in many recent studies, which can interpret almost all of the previously simulated bifurcation processes with chaos in neural firing patterns. In the present paper, a comb-shaped chaotic region in a two- dimensional parameter space was reproduced, which presented different processes of period-adding bifurcations with chaos with changing one parameter and fixed the other parameter at different levels. In the biological experiments, different period-adding bifurcation scenarios with chaos by decreasing the extra-cellular calcium concentration were observed from some neural pacemakers at different levels of extra-cellular 4-aminopyridine concentration and from other pacemakers at different levels of extra-cellular caesium concentration. By using the nonlinear time series analysis method, the determin- istic dynamics of the experimental chaotic firings were investigated. The period-adding bifurcations with chaos observed in the experiments resembled those simulated in the comb-shaped chaotic region using the HR model. The experimental results show that period-adding bifurcations with chaos are preserved in different two-dimensional parameter spaces, which provides evidence of the existence of the comb-shaped chaotic region and a demonstration of the simulation results in dif- ferent two-dimensional parameter spaces in the HR neuron model. The results also present relationships between different firing patterns in two-dimensional parameter spaces.
