Magma hybridization in the Western Tatra Mts. granitoid intrusion (S-Poland, Western Carpathians)
In the Variscan Western Tatra granites hybridization phenomena such as mixing and mingling can be observed at the contact of mafic precursors of dioritic composition and more felsic granitic host rocks. The textural evidence of hybridization include: plagioclase-K-feldspar-sphene ocelli, hornblende- and biotite-rimmed quartz ocelli, plagioclase with Ca-rich spike zonation, inversely zoned K-fel...
متن کاملThe species of the Chthonius heterodactylus group (Arachnida, Pseudoscorpiones, Chthoniidae) from the eastern Alps and the Carpathians.
The species of the subgenus Chthonius (Chthonius) C.L. Koch, 1843 displaying a sigmoid fixed chelal finger from the Eastern Alps and the Carpathians, assigned to the informal heterodactylus species-group, are revised and a key given for their identification. The following species are present in this area: Chthonius cavernarum Ellingsen, 1909 (Italy, Romania, Slovenia), C. heterodactylus Tömösvá...
متن کاملComplex distribution patterns of di-, tetra-, and hexaploid cytotypes in the European high mountain plant Senecio carniolicus (Asteraceae).
DNA ploidy levels were estimated using DAPI-flow cytometry of silica-dried specimens of the European mountain plant Senecio carniolicus (Asteraceae), covering its entire distribution area in the Eastern Alps (77 populations, 380 individuals) and the Carpathians (five populations, 22 individuals). A complex pattern of ploidy level variation (2x, 4x, 5x, 6x, and 7x cytotypes) was found in this sp...
متن کاملEvolutionary Biology: The Origins of Two Sexes
Evidence is accumulating that in the green algae the evolution of female and male gametes differing in size--anisogamy--involves genes linked to the mating-type locus, as was predicted theoretically.
متن کاملEvolutionary cell biology: two origins, one objective.
All aspects of biological diversification ultimately trace to evolutionary modifications at the cellular level. This central role of cells frames the basic questions as to how cells work and how cells come to be the way they are. Although these two lines of inquiry lie respectively within the traditional provenance of cell biology and evolutionary biology, a comprehensive synthesis of evolution...
