As normally happens in a diverse scientific community, the interpretations of specialized lunar data have reflected the precepts in the various specialized fields. Constant promotion of the broadest overviews between these diverse fields is appropriate to identify processes or phenomenon recog- nized in one avenue of investigation which may have great importance in explaining the data of other specialities. -

Hyperspectral Imaging of Cuttlefish Camouflage Indicates Good Color
Hyperspectral imaging of cuttlefish camouflage indicates good color match in the eyes of fish predators Chuan-Chin Chiaoa,b,1, J. Kenneth Wickiserc, Justine J. Allena,d, Brock Genterc, and Roger T.

Kimball Romney, University of California, Irvine, CA, and approved April 13, 2011 (received for review December 30, 2010) Camouflage is a widespread phenomenon throughout nature and hyperspectral image is typically captured by scanning the 2D an important antipredator tactic in natural selection. Many visual sensor either spectrally or spatially in the third dimension to predators have keen color perception, and thus camouflage acquire the 3D data cube of which the z axis normally represents patterns should provide some degree of color matching in addition the reflectance spectrum of the corresponding point in the scene. to other visual factors such as pattern, contrast, and texture. Camouflage is the primary defense of coleoid cephalopods Quantifying camouflage effectiveness in the eyes of the predator (octopus, squid, and cuttlefish) and their rapidly adaptable body is a challenge from the perspectives of both biology and optical patterning system is among the most sophisticated in the animal imaging technology. Here we take advantage of hyperspectral kingdom (21–23). The expression of camouflaged body patterns imaging (HSI), which records full-spectrum light data, to simulta- in cuttlefish is a visually driven behavior. -

Mimicry - Ecology - Oxford Bibliographies 12/13/12 7:29 PM Mimicry David W. Kikuchi, David W. Pfennig Introduction Among nature’s most exquisite adaptations are examples in which natural selection has favored a species (the mimic) to resemble a second, often unrelated species (the model) because it confuses a third species (the receiver). For example, the individual members of a nontoxic species that happen to resemble a toxic species may dupe any predators by behaving as if they are also dangerous and should therefore be avoided. In this way, adaptive resemblances can evolve via natural selection. When this phenomenon—dubbed “mimicry”—was first outlined by Henry Walter Bates in the middle of the 19th century, its intuitive appeal was so great that Charles Darwin immediately seized upon it as one of the finest examples of evolution by means of natural selection. Even today, mimicry is often used as a prime example in textbooks and in the popular press as a superlative example of natural selection’s efficacy. Moreover, mimicry remains an active area of research, and studies of mimicry have helped illuminate such diverse topics as how novel, complex traits arise; how new species form; and how animals make complex decisions. General Overviews Since Henry Walter Bates first published his theories of mimicry in 1862 (see Bates 1862, cited under Historical Background), there have been periodic reviews of our knowledge in the subject area. Cott 1940 was mainly concerned with animal coloration. Subsequent reviews, such as Edmunds 1974 and Ruxton, et al. 2004, have focused on types of mimicry associated with defense from predators. -
Ten Misunderstandings About Evolution a Very Brief Guide for the Curious and the Confused by Dr
Ten Misunderstandings About Evolution A Very Brief Guide for the Curious and the Confused By Dr. Mike Webster, Dept. of Neurobiology and Behavior, Cornell Lab of Ornithology, Cornell University ([email protected]); February 2010 The current debate over evolution and “intelligent design” (ID) is being driven by a relatively small group of individuals who object to the theory of evolution for religious reasons. The debate is fueled, though, by misunderstandings on the part of the American public about what evolutionary biology is and what it says. These misunderstandings are exploited by proponents of ID, intentionally or not, and are often echoed in the media. In this booklet I briefly outline and explain 10 of the most common (and serious) misunderstandings. It is impossible to treat each point thoroughly in this limited space; I encourage you to read further on these topics and also by visiting the websites given on the resource sheet. In addition, I am happy to send a somewhat expanded version of this booklet to anybody who is interested – just send me an email to ask for one! What are the misunderstandings? 1. Evolution is progressive improvement of species Evolution, particularly human evolution, is often pictured in textbooks as a string of organisms marching in single file from “simple” organisms (usually a single celled organism or a monkey) on one side of the page and advancing to “complex” organisms on the opposite side of the page (almost invariably a human being). We have all seen this enduring image and likely have some version of it burned into our brains. -

LUNAR TOPOGRAPHIC ORTHOPHOTOMAP (LTO) AND LUNAR ORTHOPHOTMAP (LO) SERIES (Published by DMATC) Lunar Topographic Orthophotmaps and Lunar Orthophotomaps Scale: 1:250,000 Projection: Transverse Mercator Sheet Size: 25.5”x 26.5” The Lunar Topographic Orthophotmaps and Lunar Orthophotomaps Series are the first comprehensive and continuous mapping to be accomplished from Apollo Mission 15-17 mapping photographs. This series is also the first major effort to apply recent advances in orthophotography to lunar mapping. Presently developed maps of this series were designed to support initial lunar scientific investigations primarily employing results of Apollo Mission 15-17 data. Individual maps of this series cover 4 degrees of lunar latitude and 5 degrees of lunar longitude consisting of 1/16 of the area of a 1:1,000,000 scale Lunar Astronautical Chart (LAC) (Section 4.2.1). Their apha-numeric identification (example – LTO38B1) consists of the designator LTO for topographic orthophoto editions or LO for orthophoto editions followed by the LAC number in which they fall, followed by an A, B, C or D designator defining the pertinent LAC quadrant and a 1, 2, 3, or 4 designator defining the specific sub-quadrant actually covered. The following designation (250) identifies the sheets as being at 1:250,000 scale. The LTO editions display 100-meter contours, 50-meter supplemental contours and spot elevations in a red overprint to the base, which is lithographed in black and white. LO editions are identical except that all relief information is omitted and selenographic graticule is restricted to border ticks, presenting an umencumbered view of lunar features imaged by the photographic base. -

OCTOBER 2 0 0 6 �������������� http://www.universetoday.com �������������� TAMMY PLOTNER WITH JEFF BARBOUR 283 SUNDAY, OCTOBER 1 In 1897, the world’s largest refractor (40”) debuted at the University of Chica- go’s Yerkes Observatory. Also today in 1958, NASA was established by an act of Congress. More? In 1962, the 300-foot radio telescope of the National Ra- dio Astronomy Observatory (NRAO) went live at Green Bank, West Virginia. It held place as the world’s second largest radio scope until it collapsed in 1988. Tonight let’s visit with an old lunar favorite. Easily seen in binoculars, the hexagonal walled plain of Albategnius ap- pears near the terminator about one-third the way north of the south limb. Look north of Albategnius for even larger and more ancient Hipparchus giving an almost “figure 8” view in binoculars. Between Hipparchus and Albategnius to the east are mid-sized craters Halley and Hind. Note the curious ALBATEGNIUS AND HIPPARCHUS ON THE relationship between impact crater Klein on Albategnius’ southwestern wall and TERMINATOR CREDIT: ROGER WARNER that of crater Horrocks on the northeastern wall of Hipparchus. Now let’s power up and “crater hop”... Just northwest of Hipparchus’ wall are the beginnings of the Sinus Medii area. Look for the deep imprint of Seeliger - named for a Dutch astronomer. Due north of Hipparchus is Rhaeticus, and here’s where things really get interesting. If the terminator has progressed far enough, you might spot tiny Blagg and Bruce to its west, the rough location of the Surveyor 4 and Surveyor 6 landing area. -
Peter Kropotkin and the Social Ecology of Science in Russia, Europe, and England, 1859-1922
THE STRUGGLE FOR COEXISTENCE: PETER KROPOTKIN AND THE SOCIAL ECOLOGY OF SCIENCE IN RUSSIA, EUROPE, AND ENGLAND, 1859-1922 by ERIC M. JOHNSON A DISSERTATION SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY in THE FACULTY OF GRADUATE AND POSTDOCTORAL STUDIES (History) THE UNIVERSITY OF BRITISH COLUMBIA (Vancouver) May 2019 © Eric M. Johnson, 2019 The following individuals certify that they have read, and recommend to the Faculty of Graduate and Postdoctoral Studies for acceptance, the dissertation entitled: The Struggle for Coexistence: Peter Kropotkin and the Social Ecology of Science in Russia, Europe, and England, 1859-1922 Submitted by Eric M. Johnson in partial fulfillment of the requirements for the degree of Doctor of Philosophy in History Examining Committee: Alexei Kojevnikov, History Research Supervisor John Beatty, Philosophy Supervisory Committee Member Mark Leier, History Supervisory Committee Member Piers Hale, History External Examiner Joy Dixon, History University Examiner Lisa Sundstrom, Political Science University Examiner Jaleh Mansoor, Art History Exam Chair ii Abstract This dissertation critically examines the transnational history of evolutionary sociology during the late-nineteenth and early-twentieth centuries. Tracing the efforts of natural philosophers and political theorists, this dissertation explores competing frameworks at the intersection between the natural and human sciences – Social Darwinism at one pole and Socialist Darwinism at the other, the latter best articulated by Peter Alexeyevich Kropotkin’s Darwinian theory of mutual aid. These frameworks were conceptualized within different scientific cultures during a contentious period both in the life sciences as well as the sociopolitical environments of Russia, Europe, and England. This cross- pollination of scientific and sociopolitical discourse contributed to competing frameworks of knowledge construction in both the natural and human sciences. -

Developmental Effects of Environmental Light on Male Nuptial Coloration in Lake Victoria Cichlid Fish
Developmental effects of environmental light on male nuptial coloration in Lake Victoria cichlid fish Daniel Shane Wright1, Emma Rietveld1,2 and Martine E. Maan1 1 Groningen Institute for Evolutionary Life Sciences, University of Groningen, Groningen, Netherlands 2 University of Applied Sciences van Hall Larenstein, Leeuwarden, Netherlands ABSTRACT Background. Efficient communication requires that signals are well transmitted and perceived in a given environment. Natural selection therefore drives the evolution of different signals in different environments. In addition, environmental heterogeneity at small spatial or temporal scales may favour phenotypic plasticity in signaling traits, as plasticity may allow rapid adjustment of signal expression to optimize transmission. In this study, we explore signal plasticity in the nuptial coloration of Lake Victoria cichlids, Pundamilia pundamilia and Pundamilia nyererei. These two species differ in male coloration, which mediates species-assortative mating. They occur in adjacent depth ranges with different light environments. Given the close proximity of their habitats, overlapping at some locations, plasticity in male coloration could contribute to male reproductive success but interfere with reproductive isolation. Methods. We reared P. pundamilia, P. nyererei, and their hybrids under light conditions mimicking the two depth ranges in Lake Victoria. From photographs, we quantified the nuptial coloration of males, spanning the entire visible spectrum. In experiment 1, we examined developmental colour plasticity by comparing sibling males reared in each light condition. In experiment 2, we assessed colour plasticity in adulthood, by switching adult males between conditions and tracking coloration for 100 days. Results. We found that nuptial colour in Pundamilia did respond plastically to our light manipulations, but only in a limited hue range. -
THE STUDY of SATURN's RINGS 1 Thesis Presented for the Degree Of
1 THE STUDY OF SATURN'S RINGS 1610-1675, Thesis presented for the Degree of Doctor of Philosophy in the Field of History of Science by Albert Van Haden Department of History of Science and Technology Imperial College of Science and Teohnology University of London May, 1970 2 ABSTRACT Shortly after the publication of his Starry Messenger, Galileo observed the planet Saturn for the first time through a telescope. To his surprise he discovered that the planet does.not exhibit a single disc, as all other planets do, but rather a central disc flanked by two smaller ones. In the following years, Galileo found that Sa- turn sometimes also appears without these lateral discs, and at other times with handle-like appendages istead of round discs. These ap- pearances posed a great problem to scientists, and this problem was not solved until 1656, while the solution was not fully accepted until about 1670. This thesis traces the problem of Saturn, from its initial form- ulation, through the period of gathering information, to the final stage in which theories were proposed, ending with the acceptance of one of these theories: the ring-theory of Christiaan Huygens. Although the improvement of the telescope had great bearing on the problem of Saturn, and is dealt with to some extent, many other factors were in- volved in the solution of the problem. It was as much a perceptual problem as a technical problem of telescopes, and the mental processes that led Huygens to its solution were symptomatic of the state of science in the 1650's and would have been out of place and perhaps impossible before Descartes. -
