On 26–28 November 2020, the Chinese National Symposium on Systematic and Evolutionary Botany (also known as 14th Young Scholar's Symposium) was held at Xishuangbanna Tropical Botanical Garden (XTBG), Academy of Sciences (CAS) in Menglun, Yunnan Province, China. The symposium sponsored by Society China (BSC), organized Professor Yao-Wu Xing from XTBG. series has been every other year regularly l...

background : cockroaches are of vital importance medically and hygienically. they are able to contaminate foods and act as vectors of pathogenic agents such as bacteria, protozoa, and parasites to human environment either mechanically or through their digestive system. cockroaches belong to the phylum arthropoda, class insecta, and order blattodea or blattaria. to date, over 4,500 cockroach spe...

the present study provides information about the cryptinae and ichneumoninae (hymenoptera: ichneumonidae) species collected from kerman province, during 2013. a total of 12 species belonging to 10 genera of these two subfamilies were collected and identified. they were cryptus inculcator (linnaeus, 1758); dichrogaster longicaudata (thomson, 1884); dichrogaster saharator (aubert, 1964) and mesos...

Based on the Randic suggestion of the resolution of a structure into shape, size, and function an index representing structure-catabolic fate relationships of amino acids is constructed. The index obtained by multiplying three factors; (nb2 + nr), nc and M; representing shape, size and function respectively, where nb2 = number of double bonds, nr = number of rings, nc = number of carbon atoms, ...

The CMB’s B-mode polarization provides a handle on several cosmological parameters most notably the tensor-to-scalar ratio, r, and is sensitive to parameters which govern the growth of large scale structure (LSS) and evolution of the gravitational potential. These imprint CMB temperature anisotropy and cause E-to-B-mode polarization conversion via gravitational lensing. The CMB has also the pot...

The influence of the evolutionary theory is widespread in modern worldview. Due to its great explanatory power and pervasiveness, the theory of evolution should be used as the organizing theme in biology teaching. For this purpose, the essential concepts of phylogenetic systematics are useful as a didactic instrument. The phylogenetic method was the first objective set of rules to implement in ...
