近日,南昌大学生命科学学院青年教师周亚东同中科院武汉植物园科研人员合作,以“Geographic patterns and environmental correlates of taxonomic and phylogenetic diversity of aquatic plants in China”为题,在SCI期刊《Journal of Systematics and Evolution...
The contributions in this special issue clearly demonstrate the broad range of problems involved in the subject of marine biological diversity. One central theme, however, is the need for accurate ide...
By using very general and well established features of soft strong interactions we show, contrary to conventional expectations, that (i) soft final-state interactions (FSI) do not disappear for large ...
Three new types of arthropod from Cambrian intertidal lithofacies of the Elk Mound Group and Lodi Member of Wisconsin, and the Potsdam Group of Quebec are described. These arthropods are preserved ven...
This report deals with a general reexamination of the systematics of sulfosalts. It represents an update of the activity of the Sulfosalt Sub-Committee within the Commission on Ore Mineralogy of the I...
Gamma-ray burst analyses at neutrino telescopes are typically based on diffuse or stacked (i.e., aggregated) neutrino fluxes, because the number of events expected from a single burst is small. The ag...
This paper continues our development of non-parametric tests for analysing the completeness in apparent magnitude of magnitude-redshift surveys. The purpose of this third and final paper in our comple...
We study the effects of instrumental systematics on the estimation of primordial non-Gaussianity using the cosmic microwave background (CMB) bispectrum from both the temperature and the polarization a...
Systematic biology faces tremendous challenges and opportunities at the present time. This conference aims at providing an opportunity for plant systematists and evolutionary biologists to review the ...
We have investigated the odd-parity preference of the WMAP 7 year power spectrum. Our investigation shows parity asymmetry of the WMAP data (2<= l <=22) is anomalous at 4-in-1000 level. We also find i...
The type species of the Carboniferous chondrichthyan genus Lagarodus JAEKEL, 1898 is changed to Psammodus specularis TRAUTSCHOLD, 1874 because of an identification error in TRAUTSCHOLD (1874). Five mo...
Aholoplanktonic mollusc assemblage from Neogene sediments of theAzorean island SantaMaria is described and analysed to determine the age of the sediments. Sixteen taxa are documented (three heteropods...
Systemactics iS a science.which iS very important for biodiversity conservation.In this re— view,the definition,main research topicsservices and user needs of systematics are introduced。 The inform...
Based on the neutron induced fission fragment mass distribution data up to neutron energy 20MeV measured with the double kinetic energy method (KEM) and the radio active method (RAM), the systematics...
With this paper we encourage the acceptance of paraphyletic taxa in systematics of Clitellata. Recent molecular studies unmask more and more paraphyletic groups in the traditional classification; mos...
