The genus Lasinus Sharp, 1874 of the Pselaphodes complex of genera (Pselaphitae: Tyrini: Tyrina) is revised. The three so far known species, Lasinus mandarinus Raffray, 1890, Lasinus monticola Sawada, 1961 and Lasinus spinosus Sharp, 1874 are redescribed. Eight new species, Lasinus sinicus
sp. n. from China, Lasinus mikado
sp. n., Lasinus yamamotoi
sp. n., Lasinus inexpectatus
sp. n., Lasinus yakushimanus
sp. n., Lasinus amamianus
sp. n., Lasinus saoriae
sp. n., and Lasinus okinawanus
sp. n. from Japan, are described. And all species are illustrated. Lectotypes are designated for Lasinus mandarinus and Lasinus spinosus. An identification key to species of the genus Lasinus is provided. 相似文献

This paper analyzes the interaction between science, philosophy and politics (including ideology) in the early work of J. B. S. Haldane (from 1922 to 1937). This period is particularly important, not only because it is the period of Haldane's most significant biological work (both in biochemistry and genetics), but also because it is during this period that his philosophical and political views underwent their most significant transformation. His philosophical stance first changed from a radical organicism to a position far more compatible with mechanical materialism. The primary intellectual influence that was responsible for this shift was that of F. G. Hopkins. Later, Haldane came to accept Marxism and its official metaphysics, dialectical materialism, a move that let him accept the materialist conception of the world while still maintaining a resolute distance from mechanism. Throughout all these changes, what is most obvious is the influence of science on Haldane's philosophical views. An influence in the opposite direction is far less apparent.Parts of this paper are extracted from a longer work which concerns the interactions between philosophy and science throughout Haldane's scientific career (Sarkar forthcoming). The general conclusions reached here, from a consideration of Haldane's work only from 1922 to 1937 (see Section 6), remain the same for the rest of his life, as is detailed in the longer work. Thanks are due to R. S. Cohen, J. F. Crow, A. R. Fersht, J. Maynard Smith, R. C. Olby, D. Paul, M. Ruse, J. Stachel and S. Sturdy for helpful discussions and comments and criticism of the positions outlined in this paper. This is Contribution No. BTBG-92-4 from the Theoretical Biology Group, Boston University. 相似文献

During the late-glacial eruption of the Laacher See volcano 12,900 b.p. the whole area of the Neuwied Basin, middle Rhine region, was covered by several metres of the Laacher See Tephra (LST) damaging
but also partly conserving the former vegetation. This gave the unique opportunity to study plant remains in situ and to estimate
the spatial biodiversity of plant taxa within the area investigated at the end of the last glacial as if in a snapshot of
12,900 years ago. Different kinds of plant material can be found because of different preservation conditions namely imprints,
charcoal and waterlogged remains. Investigations of this material from several places within the Neuwied Basin and the Brohl
valley north of it allowed the reconstruction of the former vegetation at different scales from local to regional. This resulted
in a large scale draft of a vegetation map of the studied area also based on the distribution and the stage of soil development
at that time. As to whether thermophilous trees were already present is discussed but largely rejected.
