LA.B.1.2 The student uses the writing processes effectively. Social Studies SS.A.1.2.1: The student understands how individuals, ideas, decisions, and events can influence history. SS.B.2.2.4: The student understands how factors such as population growth, human migration, improved methods of transportation and communication, and economic development affect the use and conservation of natural resources. Science SC.G.1.2.2 The student knows that living things compete in a climatic region with other living things and that structural adaptations make them fit for an environment. National Science Education Standards: Content Standard C (K-4) - Characteristics of Organisms : Each plant or animal has different structures that serve different functions in growth, survival, and reproduction. For example, humans have distinct body structures for walking, holding, seeing, and talking. Content Standard C (5-8) - Diversity and adaptations of Organisms : Biological evolution accounts for the diversity of species developed through gradual processes over many generations. Species acquire many of their unique characteristics through biological adaptation, which involves the selection of naturally occurring variations in populations. Biological adaptations include changes in structures, behaviors, or physiology that enhance survival and reproductive success in a particular environment. -

Identification of Mutant Genes and Introgressed Tiger Salamander
www.nature.com/scientificreports OPEN Identification of Mutant Genes and Introgressed Tiger Salamander DNA in the Laboratory Axolotl, Received: 13 October 2016 Accepted: 19 December 2016 Ambystoma mexicanum Published: xx xx xxxx M. Ryan Woodcock1, Jennifer Vaughn-Wolfe1, Alexandra Elias2, D. Kevin Kump1, Katharina Denise Kendall1,5, Nataliya Timoshevskaya1, Vladimir Timoshevskiy1, Dustin W. Perry3, Jeramiah J. Smith1, Jessica E. Spiewak4, David M. Parichy4,6 & S. Randal Voss1 The molecular genetic toolkit of the Mexican axolotl, a classic model organism, has matured to the point where it is now possible to identify genes for mutant phenotypes. We used a positional cloning– candidate gene approach to identify molecular bases for two historic axolotl pigment phenotypes: white and albino. White (d/d) mutants have defects in pigment cell morphogenesis and differentiation, whereas albino (a/a) mutants lack melanin. We identified in white mutants a transcriptional defect in endothelin 3 (edn3), encoding a peptide factor that promotes pigment cell migration and differentiation in other vertebrates. Transgenic restoration of Edn3 expression rescued the homozygous white mutant phenotype. We mapped the albino locus to tyrosinase (tyr) and identified polymorphisms shared between the albino allele (tyra) and tyr alleles in a Minnesota population of tiger salamanders from which the albino trait was introgressed. tyra has a 142 bp deletion and similar engineered alleles recapitulated the albino phenotype. Finally, we show that historical introgression of tyra significantly altered genomic composition of the laboratory axolotl, yielding a distinct, hybrid strain of ambystomatid salamander. Our results demonstrate the feasibility of identifying genes for traits in the laboratory Mexican axolotl. The Mexican axolotl (Ambystoma mexicanum) is the primary salamander model in biological research. -
Time, Infinity, Recursion, and Liminality in the Writings of Jorge Luis Borges
Kevin Wilson Of Stones and Tigers; Time, Infinity, Recursion, and Liminality in the writings of Jorge Luis Borges (1899-1986) and Pu Songling (1640-1715) (draft) The need to meet stones with tigers speaks to a subtlety, and to an experience, unique to literary and conceptual analysis. Perhaps the meeting appears as much natural, even familiar, as it does curious or unexpected, and the same might be said of meeting Pu Songling (1640-1715) with Jorge Luis Borges (1899-1986), a dialogue that reveals itself as much in these authors’ shared artistic and ideational concerns as in historical incident, most notably Borges’ interest in and attested admiration for Pu’s work. To speak of stones and tigers in these authors’ works is to trace interwoven contrapuntal (i.e., fugal) themes central to their composition, in particular the mutually constitutive themes of time, infinity, dreaming, recursion, literature, and liminality. To engage with these themes, let alone analyze them, presupposes, incredibly, a certain arcane facility in navigating the conceptual folds of infinity, in conceiving a space that appears, impossibly, at once both inconceivable and also quintessentially conceptual. Given, then, the difficulties at hand, let the following notes, this solitary episode in tracing the endlessly perplexing contrapuntal forms that life and life-like substances embody, double as a practical exercise in developing and strengthening dynamic “methodologies of the infinite.” The combination, broadly conceived, of stones and tigers figures prominently in -
Cognitive Adaptations of Social Bonding in Birds Nathan J
Phil. Trans. R. Soc. B (2007) 362, 489–505 doi:10.1098/rstb.2006.1991 Published online 24 January 2007 Cognitive adaptations of social bonding in birds Nathan J. Emery1,*, Amanda M. Seed2, Auguste M. P. von Bayern1 and Nicola S. Clayton2 1Sub-department of Animal Behaviour, University of Cambridge, Cambridge CB3 8AA, UK 2Department of Experimental Psychology, University of Cambridge, Cambridge CB2 3EB, UK The ‘social intelligence hypothesis’ was originally conceived to explain how primates may have evolved their superior intellect and large brains when compared with other animals. Although some birds such as corvids may be intellectually comparable to apes, the same relationship between sociality and brain size seen in primates has not been found for birds, possibly suggesting a role for other non-social factors. But bird sociality is different from primate sociality. Most monkeys and apes form stable groups, whereas most birds are monogamous, and only form large flocks outside of the breeding season. Some birds form lifelong pair bonds and these species tend to have the largest brains relative to body size. Some of these species are known for their intellectual abilities (e.g. corvids and parrots), while others are not (e.g. geese and albatrosses). Although socio-ecological factors may explain some of the differences in brain size and intelligence between corvids/parrots and geese/albatrosses, we predict that the type and quality of the bonded relationship is also critical. Indeed, we present empirical evidence that rook and jackdaw partnerships resemble primate and dolphin alliances. Although social interactions within a pair may seem simple on the surface, we argue that cognition may play an important role in the maintenance of long-term relationships, something we name as ‘relationship intelligence’. -

Theosophical Symbology Some Hints Towards Interpretation of the Symbolism of the Seal of the Society
Theosophical Siftings Theosophical Symbology Vol 3, No 4 Theosophical Symbology Some Hints Towards Interpretation of the Symbolism of the Seal of the Society by G.R.S. Mead, F.T.S. Reprinted from “Theosophical Siftings” Volume 3 The Theosophical Publishing Society, England "A combination and a form, indeed, Where every god did seem to set his seal, To give the world assurance of a MAN." As the question is often asked, What is the meaning of the Seal of the Society, it may not be unprofitable to attempt a rough outline of some of the infinite interpretations that can be discovered therein. When, however, we consider that the whole of our philosophical literature is but a small contribution to the unriddling of this collective enigma of the sphinx of all sciences, religions and philosophies, it will be seen that no more than the barest outlines can be sketched in a short paper. In the first place, we are told that to every symbol, glyph and emblem there are seven keys, or rather, that the key may be turned seven times, corresponding to all the septenaries in nature and in man. We might even suppose, by using the law of analogy, that each of the seven keys might be turned seven times. So that if we were to suggest that these keys may be named the physiological, astronomical, cosmic, psychic, intellectual and spiritual, of which divine interpretation is the master-key, we should still be on our guard lest we may have confounded some of the turnings with the keys themselves. -
A New Species of the Genus Nasikabatrachus (Anura, Nasikabatrachidae) from the Eastern Slopes of the Western Ghats, India

We describe a new species of the endemic frog genus Nasikabatrachus,from the eastern slopes of the Western Ghats, in India. The new species is morphologically, acoustically and genetically distinct from N. sahyadrensis. Computed tomography scans of both species revealed diagnostic osteological differences, particularly in the vertebral column. Male advertisement call analysis also showed the two species to be distinct. A phenological difference in breeding season exists between the new species (which breeds during the northeast monsoon season; October to December), and its sister species (which breeds during the southwest monsoon; May to August). The new species shows 6 % genetic divergence (K2P) at mitochondrial 16S rRNA (1330 bp) partial gene from its congener, indicating clear differentiation within Nasikabatra- chus. Speciation within this fossorial lineage is hypothesized to have been caused by phenological shift in breeding during different monsoon seasons—the northeast monsoon in the new species versus southwest monsoon in N. -
The Origins of Chordate Larvae Donald I Williamson* Marine Biology, University of Liverpool, Liverpool L69 7ZB, United Kingdom
lopmen ve ta e l B Williamson, Cell Dev Biol 2012, 1:1 D io & l l o l g DOI: 10.4172/2168-9296.1000101 e y C Cell & Developmental Biology ISSN: 2168-9296 Research Article Open Access The Origins of Chordate Larvae Donald I Williamson* Marine Biology, University of Liverpool, Liverpool L69 7ZB, United Kingdom Abstract The larval transfer hypothesis states that larvae originated as adults in other taxa and their genomes were transferred by hybridization. It contests the view that larvae and corresponding adults evolved from common ancestors. The present paper reviews the life histories of chordates, and it interprets them in terms of the larval transfer hypothesis. It is the first paper to apply the hypothesis to craniates. I claim that the larvae of tunicates were acquired from adult larvaceans, the larvae of lampreys from adult cephalochordates, the larvae of lungfishes from adult craniate tadpoles, and the larvae of ray-finned fishes from other ray-finned fishes in different families. The occurrence of larvae in some fishes and their absence in others is correlated with reproductive behavior. Adult amphibians evolved from adult fishes, but larval amphibians did not evolve from either adult or larval fishes. I submit that [1] early amphibians had no larvae and that several families of urodeles and one subfamily of anurans have retained direct development, [2] the tadpole larvae of anurans and urodeles were acquired separately from different Mesozoic adult tadpoles, and [3] the post-tadpole larvae of salamanders were acquired from adults of other urodeles. Reptiles, birds and mammals probably evolved from amphibians that never acquired larvae. -
Dragonlore Issue 37 08-11-03
The bird was a Rukh and the white dome, of course, was its egg. Sindbad lashes himself to the bird’s leg with his turban, and the next morning is whisked off into flight and set down on a mountaintop, without having excited the Rukh’s attention. The narrator adds that the Rukh feeds itself on serpents of such great bulk that they would have made but one gulp of an elephant. In Marco Polo’s Travels (III, 36) we read: Dragonlore The people of the island [of Madagascar] report that at a certain season of the year, an extraordinary kind of bird, which they call a rukh, makes its appearance from The Journal of The College of Dracology the southern region. In form it is said to resemble the eagle but it is incomparably greater in size; being so large and strong as to seize an elephant with its talons, and to lift it into the air, from whence it lets it fall to the ground, in order that when dead it Number 37 Michaelmas 2003 may prey upon the carcase. Persons who have seen this bird assert that when the wings are spread they measure sixteen paces in extent, from point to point; and that the feathers are eight paces in length, and thick in proportion. Marco Polo adds that some envoys from China brought the feather of a Rukh back to the Grand Kahn. A Persian illustration in Lane shows the Rukh bearing off three elephants in beak and talons; ‘with the proportion of a hawk and field mice’, Burton notes. -
