ALTERNATIVE OCCURRENCE OF TWO OVARIAN FUNCTIONS IN THE ADULT PSEUDOSCORPION, GARYPUS JAPONICUS BEIERToshiki MAKIOKA1976Volume 27Issue 1 Pages 8-15
Published: 1976
Released on J-STAGE: March 29, 2007
JOURNAL FREE ACCESSA general pattern of occurrence of the oogenic and secretory functions was studied in adult ovaries of the pseudoscorpion, Garypus japonicus. Both functions occurred alternatively and caused three morphological types or four functional phases of the ovary to appear. The relations among the morphological types and/or the functional phases were discussed.View full abstractDownload PDF (550K) -

JOURNAL FREE ACCESSOribatid mite fauna was investigated in October, 1975 along the north east slope of Mt. Mitsu-toge, Central Japan. Soil samples were taken at each 100m height from 700m to 1750m above the sea level. The mite density/m2 changed in accordance with water contents of soil as well as organic matter contents of soil, while the species number gradually fell along with the rise of altitude and at the same time the fall of temperature. A total of 104 species collected were classified into several groups according to their range of appearence. Dominant species, 18 in number, were also classified in the same manner. Quadroppia quadricarinata, Tectocepheus velatus and Oppiella nova become dominant throughout the area investigated.View full abstractDownload PDF (2561K) -

JOURNAL FREE ACCESSA thin layer found in the perivitelline space of the horseshoe crab eggs was studied anatomically, histochemically and electron-microscopically. The layer exists from the stage of unfertilized egg to that of germ-disc formation. In the early stages it seems to be of only viscous structure containing mucopolysaccharide. However, in the late blastula stage, a thin membranous structure which can tear off by forceps appears on the outer surface of the layer. Accompanying with the swelling of the inner egg membrane, the viscous layer and the thin membranous structure are attached on the outer surface of the inner egg membrane, and then disappear. We propose a thin membrane in regard to all these structures.View full abstractDownload PDF (1403K) -
