A general account is given of studies made on experimental populations Drosophila melanogaster which are exposed to radiations. consideration the frequencies lethals, semilethals, and subvitals within estimates adaptive values suggests that heterotic gene combinations have been developed some these populations. The bearing results estimation radiation damage resulting from mutation briefly mentioned.
HE existence of variation among the individual members a populationT has been recognized for centuries ; biological importance this begun to be understood only in past few decades.Formerly type specimen was regarded as representing species now it is realized that adequate representation obtainable through series specimens.Population geneticists 1920's and 1930's were active studying genetic component variability.CHETVERIKOV ( 1926, 1927), TIMOFEEFF-RES-SOVSKY TIMOFEEFF-RESSOVSKY (1927)...
Information concerning mechanistic processes underlying changes in vital rates and ultimately population growth rate is required to monitor impacts of environmental change on wildlife. We estimated age-specific survival examined factors influencing for a threatened Steller sea lions (Eumetopias jubatus) southeastern Alaska. used mark-recapture models data from 1,995 individuals marked at approximately one month age four five rookeries Alaska, resighted Oregon the Bering Sea. Average annual...
Abstract Studies of health, survival, and development juvenile Alaskan Steller sea lions ( Eumetopias jubatus , SSL) require accurate estimates age for wild‐captured animals. However, the value accuracy several potential predictors have not been assessed with data from known‐age free‐ranging During 2001–2005, forty‐six individual SSL originally branded or tagged at ≤6 mo were recaptured by Alaska Department Fish Game (ADF&G). Using a series general linear models, we evaluated ability...
ABSTRACT Steller sea lion ( Eumetopias jubatus ) pups n = 366) were hot‐branded at Lowrie Island, Southeast Alaska, USA, in June 2001 and 2002 for vital‐rates studies. To assess potential mortality following branding, we estimated weekly survival to 12 weeks postbranding using mark‐recapture models. Survival estimates ranged from 0.984/week 0.988/week, or 0.868 over the 12‐week period; varied little with sex, year, capture area; higher larger than smaller male unexpectedly lower female pups....

Crosses between resistant lines of D. melanogaster, developed independently by the same method selection over some twenty generations, give an F1 population resistance as parent and F2 with significantly lower a mortality distribution greater variance. These phenomena indicate that two have achieved consolidating different combinations factors for resistance. The significance this finding is discussed in light other recent evidence gene pool integrated whole.
Measurements of the ratio hatched eggs to total in randomly breeding and inbred populations Drosophila melanogaster show that two differ strikingly consistently. In former is high its variance low; latter situation reversed. The embryo has a low variable probability developmental success even very constant environment. Recent attempts apply information theory cybernetics biological phenomena suggest new way looking at these facts employing concepts redundancy, noise equivocation with respect...
In an effort to find common ground between the fields of population and developmental genetics, techniques have been worked out for observing measuring some embryonic characters in Drosophila melanogaster. Measurements made on rates three strains show that each has its own pattern. These characteristic patterns development are evidence way which genetic system a produces array adult phenotypes by effecting set biochemical events.

Abstract The Hawaii Undersea Military Munitions Assessment (HUMMA) was designed to develop methodologies for surveying and assessing a historic deep-water munitions sea disposal site determine the potential impact of ocean environment on sea-disposed those that use it. HUMMA is most comprehensive investigation conducted in United States look at both chemical conventional munitions. Recognizing each poses unique logistical environmental challenges, approach emphasizes adaptability. Here, we...
<b>Medical Genetics: Principles and Practice,</b>by James J. Nora F. Clarke Fraser, 399 pp, 226 illus, $20, Lea & Febiger, 1974. These two books illustrate ways of presenting a subject to the student. Ford writes an extended essay explaining how principles genetics apply medicine. Fraser describe syndromes genetic disease in framework principles. During last 20 years, medicine, like most subjects, has been enormously engorged by information explosion; revolutionized development molecular...
