INFORMATION TO USERS This reproduction was made from a copy of a document sent to us for microfilming. While the most advanced technology has been used to photograph and reproduce this document, the quality of the reproduction is heavily dependent upon the quality of the material submitted. The following explanation of techniques is provided to help clarify markings or notations which may appear on this reproduction. 1.The sign or “target” for pages apparently lacking from the document photographed is “Missing Page(s)”. If it was possible to obtain the missing page(s) or section, they are spliced into the film along with adjacent pages. This may have necessitated cutting through an image and duplicating adjacent pages to assure complete continuity. 2. When an image on the film is obliterated with a round black mark, it is an indication of either blurred copy because of movement during exposure, duplicate copy, or copyrighted materials that should not have been filmed. For blurred pages, a good image of the page can be found in the adjacent frame. If copyrighted materials were deleted, a target note will appear listing the pages in the adjacent frame. 3. When a map, drawing or chart, etc., is part of the material being photographed, a definite method of “sectioning” the material has been followed. It is customary to begin filming at the upper left hand corner of a large sheet and to continue from left to right in equal sections with small overlaps. If necessary, sectioning is continued again—beginning below the first row and continuing on until complete. 4. For illustrations that cannot be satisfactorily reproduced by xerographic means, photographic prints can be purchased at additional cost and inserted into your xerographic copy. These prints are available upon request from the Dissertations Customer Services Department. 5. Some pages in any document may have indistinct print. In all cases the best available copy has been filmed. University Micrcxilms International 300 N.

    Zurich Open Repository and Archive University of Zurich Main Library Strickhofstrasse 39 CH-8057 Zurich www.zora.uzh.ch Year: 2012 Reproductive seasonality in captive wild ruminants: implications for biogeographical adaptation, photoperiodic control, and life history Zerbe, Philipp Abstract: Zur quantitativen Beschreibung der Reproduktionsmuster wurden Daten von 110 Wildwiederkäuer- arten aus Zoos der gemässigten Zone verwendet (dabei wurde die Anzahl Tage, an denen 80% aller Geburten stattfanden, als Geburtenpeak-Breite [BPB] definiert). Diese Muster wurden mit verschiede- nen biologischen Charakteristika verknüpft und mit denen von freilebenden Tieren verglichen. Der Bre- itengrad des natürlichen Verbreitungsgebietes korreliert stark mit dem in Menschenobhut beobachteten BPB. Nur 11% der Spezies wechselten ihr reproduktives Muster zwischen Wildnis und Gefangenschaft, wobei für saisonale Spezies die errechnete Tageslichtlänge zum Zeitpunkt der Konzeption für freilebende und in Menschenobhut gehaltene Populationen gleich war. Reproduktive Saisonalität erklärt zusätzliche Varianzen im Verhältnis von Körpergewicht und Tragzeit, wobei saisonalere Spezies für ihr Körpergewicht eine kürzere Tragzeit aufweisen. Rückschliessend ist festzuhalten, dass Photoperiodik, speziell die abso- lute Tageslichtlänge, genetisch fixierter Auslöser für die Fortpflanzung ist, und dass die Plastizität der Tragzeit unterstützend auf die erfolgreiche Verbreitung der Wiederkäuer in höheren Breitengraden wirkte. A dataset on 110 wild ruminant species kept in captivity in temperate-zone zoos was used to describe their reproductive patterns quantitatively (determining the birth peak breadth BPB as the number of days in which 80% of all births occur); then this pattern was linked to various biological characteristics, and compared with free-ranging animals. Globally, latitude of natural origin highly correlates with BPB observed in captivity, with species being more seasonal originating from higher latitudes.

  • Photoperiodism in Hamsters: Abrupt Versus Gradual Changes in Day Length Differentially Entrain Morning and Evening Circadian Oscillators
    Photoperiodism in Hamsters: Abrupt Versus Gradual Changes in Day Length Differentially Entrain Morning and Evening Circadian Oscillators Michael R. Gorman,*,‡,1 David A. Freeman,§,2 and Irving Zucker*,† Departments of *Psychology and †Integrative Biology, University of California, Berkeley, CA 94720; ‡Department of Psychology, University of Michigan, Ann Arbor, MI 48109; and §Department of Physiology and Neurobiology, University of Connecticut, Storrs, CT 06269 Abstract In studies of photoperiodism, animals typically are transferred abruptly from a long (e.g., 16 h light per day [16L]) to a short (8L) photoperiod, and circadian oscillators that regulate pineal melatonin secretion are presumed to reentrain rapidly to the new photocycle. Among rats and Siberian hamsters, however, reentrainment rates vary de- pending on whether additional darkness is added to morning or evening, and a subset of hamsters (nonresponders) fails ever to reentrain normally to short photoperiods. The authors assessed whether several short-day responses occurred at different rates when darkness was extended into morning versus evening hours and the effectiveness of abrupt versus gradual shortening in day lengths (DLs). Entrainment patterns of photoresponsive hamsters also were compared to those of photononresponsive hamsters. Responsive hamsters transferred on a single day from 16L to 8L underwent more rapid gonadal regression, weight loss, decreases in follicle-stimulating hormone titers, and expansion of nocturnal locomotor activity when darkness was added to morning versus evening. When the dark phase was extended gradually by 8 h over 16 weeks, short-day responses occurred at the same rate whether darkness was appended to morning or evening or was added symmetrically.

Photoperiodism in pigs. Studies on timing of male puberty and melatonin. Doctoral thesis ISSN 1401-6257, ISBN 91-576-5901-X. The routine castration of male piglets, which is performed in many countries to avoid boar taint in meat, is a cause for great concern in terms of animal welfare. Castrates also have reduced feed efficiency and more fat than do entire males. More of the ingested energy therefore goes to fat tissue than to muscle tissue. The European wild boar is a seasonal short-day breeder and although domestic pigs breed all year round there are indications that they remain responsive to photoperiod. Since boar taint is closely associated with male sexual maturation, the use of artificial light regimens to delay puberty could be a non-invasive method of reducing boar taint in entire males. Therefore, a series of experiments were performed in order to study photoperiodism in young pigs. In two experiments, matched winter-born siblings of crossbred males were allocated after weaning to either one of two light-sealed rooms with high-intensity light regimens or a conventional stable environment. In the first study, groups subjected to an 'artificial autumn' treatment and an 'artificial spring' treatment were compared with a 'natural spring' group.

  • 15. Photoperiodism
    15. PHOTOPERIODISM Photoperiodism is the phenomenon of physiological changes that occur in plants in response to relative length of day and night (i.e. photoperiod). The response of the plants to the photoperiod, expressed in the form of flowering is also called as photoperiodism. The phenomenon of photoperiodism was first discovered by Garner and Allard (1920). Depending upon the duration of photoperiod, the plants are classified into three categories. 1. Short day plants (SDP) 2. Long day plants (LDP) 3. Day neutral plants (DNP) 1. Short day plants These plants require a relatively short day light period (usually 8-10 hours) and a continuous dark period of about 14-16 hours for subsequent flowering. These plants are also known as long-night plants E.g. Rice, coffee, soybean, tobacco and chrysanthemum • In short day plants, the dark period is critical and must be continuous. If this dark period is interrupted with a brief exposure of red light (660-665 nm wavelength), the short day plant will not flower. • Maximum inhibition of flowering with red light occurs at about the middle of critical dark period. • However, the inhibitory effect of red light can be overcome by a subsequent exposure with far-red light (730-735 mm wavelength) • Interruption of the light period with red light does not have inhibitory effect on flowering in short day plants. • Prolongation of the continuous dark period initiates early flowering. 2. Long day plants These plants require longer day light period (usually 14-16 hours) in a 24 hours cycle for subsequent flowering. These plants are also called as short night plants.

Entomol. 118: 1–13, 2021 http://www.eje.cz doi: 10.14411/eje.2021.001 REVIEW Insect photoperiodism: Bünning’s hypothesis, the history and development of an idea DAVID SAUNDERS 21, Leadervale Road, Edinburgh EH16 6PB, Scotland, United Kingdom; e-mail: david59.saunders@mypostoffi ce.co.uk Key words. Insects, photoperiodism, diapause, Bünning’s hypothesis, clock models Abstract. In insects, the photoperiodic system comprises a linked sequence of events from photoreception to fi nal seasonally- appropriate phenotypes such as overwintering diapause. The fi rst and last of these events are reasonably well known, but central phenomena such as those distinguishing short from long days (time measurement) and the nature, accumulation and transfer of this information through development, metamorphosis and sometimes across generations remains obscure. Bünning’s intuitive suggestion that photoperiodic time measurement was a function of the circadian system, made eight decades ago, however, has provided a framework for numerous studies investigating these connections. This review examines the development of Bünning’s hypothesis from its origin in plants to the physiology of diapause in insects. Despite considerable inter-species differences, a close and probably causal relationship between circadian rhythmicity and photoperiodism is indicated. INTRODUCTION cadian rhythmicity. This approach revealed many parallels In 1936, the German plant physiologist Erwin Bünning between the two time-measuring systems, but progress suggested that time measurement inherent in the photoper- remained slow, mainly because the fundamental nature of iodic phenomenon was a function of the circadian system circadian rhythmicity itself was largely unknown.

Photosynthesis occurs in plants, algae, ________________________WORLD TECHNOLOGIES________________________ and many species of bacteria, but not in archaea. Photosynthetic organisms are called photoautotrophs, since they can create their own food. In plants, algae, and cyanoba- cteria, photosynthesis uses carbon dioxide and water, releasing oxygen as a waste product. Photosynthesis is vital for all aerobic life on Earth. As well as maintaining the normal level of oxygen in the atmosphere, nearly all life either depends on it directly as a source of energy, or indirectly as the ultimate source of the energy in their food (the exceptions are chemoautotrophs that live in rocks or around deep sea hydrothermal vents). The rate of energy capture by photosynthesis is immense, approximately 100 terawatts, which is about six times larger than the power consumption of human civilization. As well as energy, photosynthesis is also the source of the carbon in all the organic compounds within organisms' bodies.
