[an integrated theory of natural control of animal populations].since the twenties of our century, at least 15 theories worth discussing have been developped which intend to explain the causes of natural control of animal populations (for details see schwerdtfeger, 1968). an attempt is made to integrate the different-partly contrary-ideas and new results into a general theory. the basis to start from is the cybernetic principle of feed-back mechanism introduced into population dynamics by wilbert (1962): an actual value (e.g. the inside temperature of a refr ...196828306898

[how the circannual sexual cycle of the malefield vole is determined (author's transl)].experiments were carried out on male field voles which have been captured in january. the resting sexual state of the animals at this time was determined by examination of the testis and of the genital tract during unilateral castration or by exploratory laparatomy. they were subsequently bred for 30 days in a climatic room, during which time they were fed on winter or spring grass, which has been preserved by freezing. 10 it was observed that a complete return to full sexual activity (from the ...1975772187
late dna replicaion of x chromosomes in female and pseudofemale cells of microtus agrestis.the late replication pattern of the short arms of the x chromosomes of microtus agrestis was studied in female cells and in cells with 2 x chromosomes of male origin by means of the budr-giemsa technique and of 3h-thymidine labelling. the light absorption of giemsa stained chromosome sections which were unifilarly substituted with budr (labelled), was found to be 59.2% of that of unlabelled chromosomes. in female cells, asynchrony of dna replication of both x chromosomes indicated the presence o ...197553180
heteropyknosis of the chromosomes in liver cells of different ploidy: a nuclear image study.the chromatin densities of feulgen-stained diploid, tetraploid, octoploid and binucleate cells of smear preparations of the liver of female field voles, microtus agrestis, were examined by means of image analysis. the ratio of the areas of flattened nuclei of 2n, 4n and 8n ploidy was about 1 : 1.62 :2.60 and that of the relative dna content 1 : 2 : 4. in flattened polyploid nuclei, the chromosomes are more densely arranged than in diploid. in diploid nuclei, absolutely and percentually smaller a ...19751108870

spermatogenesis in mature and regressed testes of the vole (microtus agrestis).eight stages of spermatogenesis, each with a characteristic frequency and germ cell association could be recognized in the vole. there was no difference between laboratory bred and field animals in the frequency of the stages. counts of the different types of germ cell showed that there was considerable cell loss during spermatogonial mitotic and spermatocytic meiotic divisions. only 60% of germ cells became spermatozoa in sexually mature animals, and 19% in the regressing testes of voles expose ...19751095738

[linear differentiation of the x-chromosomes of the field vole microtus agrestis].morphology of the fibroblasts x-chromosomes obtained from the female field vole microtus agrestis and cultured for 4--5 hr before fixation in 5-bromodeoxyuridine, was studied. a clear differential condensation along the lenght of the whole x-chromosome was observed. a difference between homologues in the degree of uneven condensation was noted both in the short arm (facultative heterochromatin) and in the long arm (constitutive heterochromatin).19751118897

visualization of nucleolar organizer regions im mammalian chromosomes using silver staining.a simple ammoniacal silver staining procedure, designated ag-as, differentially stains the chromosomal locations of ribosomal dna in certain mammalian species. this was critically demonstrated by ag-as staining of the nucleolus organizer regions in karyotypes of the same species and cell lines used for locating the ribosomal cistrons by dna/rna in situ hybridization. with ag-as, silver stained nors (ag-nors) are visualized as black spherical bodies on yellow-brown chromosome arms. ag-nors were v ...197553131
plasma and pituitary levels of lh in field voles, microtus arvalis, reared under two different photoperiods.10 plasma lh levels were measured in voles reared under long (15 l: 9 d) or short (10 l: 14 d) light photoperiods by radioimmunoassay from a rat lh-anti ovine lh system. 20 the number of animals exhibiting a detectable lh level (i.e. greater than 1 ng per ml) and the mean plasma lh values were higher for long days than for short days in spite of a very large variability between animals. 30 the sensitivity of the hypophysis towards lh. rh increased after gonadectomy, but is not controlled by the ...1975772188
mating, ovulation and corpus luteum function in the vole, microtus agrestis.a study of the relationship between the mating vehaviour of the vole and the induction of ovulation and cl function is described. a single intromission or an injection of lh-rf constitute stimuli which induce ovulation, but normally give rise to cl that degenerate soon after formation. more prolonged mating, or mechanical stimulation of the vagina and cervix given after a separate ovulatory stimulus, result in the maintenance of the cl. mechanical genital stimulation is effective in inducing cl ...19751089153
