Book excerpt: Excerpt from Biological Bulletin of the Marine Biological Laboratory, Woods Hole, Mass, Vol. 19: June November, 1910 The past decade has witnessed greatly renewed interest in the problems of sex determination, due very largely to the study of hybridization and the broad application of the results. Con currently the investigation of the germ cells has increased in amount in a geometrical ratio; never before have these cells so fully engaged the thoughts of biologists, and our knowledge of the complex chromosomal activities has increased to an extent unpredicted.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Biological Bulletin of the Marine Biological Laboratory, Vol. 29: Woods Hole, Mass A study Of this material by my students and myself has brought to light a situation so interesting, but withal so intricately com plex, that I almost despair of being able to render an intelligible account of it. Yet I cannot but be impressed with the unique ness Of the data and with the fact that it contains clews, afforded by no other material, as to methods Of attacking some Of the problems Of the mechanics Of hereditary transmission and Of the development Of organic symmetry. In presenting the results Of the study Of the heredity Of band and scute anomalies I have found that the problems Of heredity, and that Of the symmetrical distribution Of these inherited characters among the quadruplet embryos, are inseparably parts Of a larger problem that has to do with the mechanics Of organic symmetry. When, for example, it is found that a bilateral anomaly in a mother is inherited unilaterally in the various Offspring and appears in reversed symmetrical relations in twins, we have something more than a case of simple inherit ance. When again we find a unilateral anomaly in one pair appearing bilaterally without reversed symmetry in the opposite pair we see the problem in a more complex form. When, still further we note that an anomaly of a single scute in the mother is inherited as such in some of the Offspring and as a whole series Of anomalous Scutes (a band anomaly) in others, we begin to Suspect that the problem is too intricate for any Simple solution and that only in certain of its aspects is it likely to yield to analysis. Yet it is our duty to carry the analysis as far as our data allows. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Unfortunately he used eggs under pressure. Mem brane formation as a progressive wave beginning at the site of sperm-entrance has been observed by Wilson who, however, is not at all sure. He says (in a footnote): I have often observed that the formation of the membrane, in T oxopneustes, proceeds like a wave from the entrance-point around the periphery, but this is often irregular. Ries followed the fertilization with the cinematograph; he observed changes which indicated that the membrane forms first at one point.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Biological Bulletin, Vol. 22: Of the Marine Biological Laboratory, Woods Hole, Mass In the preceding paper we presented certain facts concerning ponds, together with a statement of succession in the pond at the head of Lake Michigan, without entering into its causes . Succession in ponds is due to many causes. It is only under the most favorable conditions that we can separate these causes one from another without long and careful investigation. The first attempts of ecologists in this line were considerations of the obvious general facts, such as the accumulation of organic detritus and the increased denseness of vegetation. We can give hen.1 hint at the more specific changes in the ponds and the relations of these to fish. The subject is one for cooperative, research. At present some of the workers and the necessary funds are not available, and the ponds are being destroyed rapidly. It is therefore improbable that the study can be carried further. This paper deals with the results of a preliminary investigation of the ponds for the purpose of learning something of the causes of distribution and succession of fish and other organisms in ponds. II. The Present Character And Content of The Ponds. The ponds with which we are concerned are shown on the map, p.131, of the preceding paper of this series. This map is essential to the understanding of the data of the present paper. Tin ponds here considered are an ecological age series, ecological age being determined by a study of amount of sand bottom, humus, etc., as shown in Table I. below. The physiographic history of the region is in full accord with the facts used in deciding age though in this case physiographic history is not essential to the decision. The pond designated as I is ecologically youngest, 14 the oldest, and the others intermediate. The measurements, analyses, and quantitative study were carried out on Pond i.c (west section), 7a, and 14b of the map. Some qualitative records from the other parts of pond 5c, from 5b, and 4d, are included with those of the ponds in which the other work has been done.
