Ophiuroids were sampled from sandy beaches, sea shores and seaweed as associated fauna, continental shelf and continental slope (until ca. 800 m depth). It was analyzed 28.942 ophiuroids from 39 species and 8 families, and the highest species richness occurred on the continental shelf. Amphiuridae was the most representative family, mainly on the internal continental shelf, followed by Ophiuridae, which mainly occurred in greater depth areas.

Ecomorfologia e uso de recursos das espécies de Chironius (Serpentes, Colubridae) na Serra do Mar /

Rodrigues, Murilo Guimarães. January 2007 (has links)
Orientador: Otavio Augusto Vuolo Marques / Banca: Marcio Roberto Costa Martins / Banca: Denise de Cerqueira Rossa Feres / Resumo: Foram analisados exemplares das cinco espécies de Chironius (C. bicarinatus, C. exoletus, C. foveatus, C. fuscus e C. laevicollis), provenientes da Floresta Atlântica na Serra do Mar, incluindo os estados do Paraná, São Paulo e Rio de Janeiro. Todas as espécies foram caracterizadas em relação à morfologia, dieta e uso do ambiente. O dimorfismo sexual no tamanho de corpo é variável entre as espécies: machos de C. bicarinatus e C. foveatus são maiores que as fêmeas conspecíficas, ao passo que em C. fuscus e C. laevicollis não existe dimorfismo sexual de tamanho, e em C. exoletus, as fêmeas são maiores. Essas diferenças sugerem que o comportamento de combate ritual, registrado em algumas espécies não esteja difundido em todos representantes do gênero. A comparação interespecífica evidência diferenças marcantes na morfologia e dieta: Chironius laevicollis tem corpo grande, maior robustez, a menor cauda e dieta baseada em anfíbios terrestres, características condizentes com o hábito terrestre; C. fuscus, tem corpo pequeno, robustez intermediária e alimenta-se principalmente de anuros terrestres, indicando hábito predominantemente terrestre; C. bicarinatus tem corpo médio, robustez intermediária e dieta baseada em anuros arborícolas e terrestres, sugerindo que forrageia freqüentemente nos dois ambientes; C. exoletus possui corpo pequeno, é pouco robusta e apresa principalmente anuros arborícolas, indicando que forrageia principalmente no substrato arbóreo, e por fim, C. foveatus possui o maior tamanho corporal, menor robustez, a maior cauda e dieta baseada em anuros arborícolas, o que indica ser a espécie mais arborícola do grupo. O ancestral hipotético desse grupo possuía tamanho médio de corpo e cauda, era semi-arborícola e alimentava-se de anfíbios terrestres e arborícolas. / Abstract: We explored the relationship of morphology, diet and habitat use in five sympatric species of Chironius (C. bicarinatus, C. exoletus, C. foveatus, C. fuscus and C. laevicollis) from Serra do Mar, eastern Brazil. Sexual dimorphism in body length varies among species: males C. bicarinatus and C. foveatus are larger than conspecific females, whereas no sexual dimorphism in body size is recorded for C. fuscus and C. laevicollis, and female C. exoletus is the larger sex. Such differences suggest that ritual combat (already recorded in the genus Chironius) may be absent in some species. Interespecific comparison shows differences in morphology and diet: Chironius laevicollis has large body size and the smallest tail, is more stout, and prey on terrestrial anurans, characters that may reflect terrestrial habit; C. fuscus, has small body length, medium stoutness and feed on terrestrial anurans, indicating a predominant terrestrial habit; C. bicarinatus has medium body size and stoutness, preying on terrestrial and arboreal anurans, suggesting a semi arboreal habit; C. exoletus has small and slender body and prey on arboreal anurans, indicating an arboreal habit, and finally C. foveatus has the largest body size and tail length, is more slender, and feed on arboreal anurans, thus may been the most arboreal species of the group. Hypothetic ancestor of this clade had medium body and tail length, was semi arboreal and fed on terrestrial and arboreal anurans. / Mestre

Serpent Imagery in William Blake's Prophetic Works

Shasberger, Linda M. 12 1900 (has links)
William Blake's prophetic works are made up almost entirely of a unique combination of symbols and imagery. To understand his books it is necessary to be aware that he used his prophetic symbols because he found them apt to what he was saying, and that he changed their meanings as the reasons for their aptness changed. An awareness of this manipulation of symbols will lead to a more perceptive understanding of Blake's work. This paper is concerned with three specific uses of serpent imagery by Blake. The first chapter deals with the serpent of selfhood. Blake uses the wingless Uraeon to depict man destroying himself through his own constrictive analytic reasonings unenlightened with divine vision. Man had once possessed this divine vision, but as formal religions and a priestly class began to be formed, he lost it and worshipped only reason and cruelty. Blake also uses the image of the serpent crown to characterize priests or anyone in a position of authority. He usually mocks both religious and temporal rulers and identifies them as oppressors rather than leaders of the people. In addition to the Uraeon and the serpent crown, Blake also uses the narrow constricted body of the serpent and the encircled serpent to represent narrowmindedness and selfish possessiveness. The second chapter deals with the serpent as a symbolic force of energy itself. Blake uses the serpent to represent birth, the life force, guardian of life forces, inner strength, resurrection, forces of destruction, and rebellion against tyranny. The Orc figure, a mythological creation of Blake, is the major representative of all phases of energy. He is a Promethean figure of rebellion and often described by Blake as having a "serpent body." His birth represents the awakening of a terrible, uncontrolled energy which will bring war, destruction, and death. He is an "eternal viper" with "ever-hissing jaws." Blake often uses this rebellious energy to deal with specific political issues in America, Ahania and Tiriel. The "serpent-formed transgressor of God's law" is also in rebellion against the binding, constricting laws of religion, and in a larger sense, against the visionless state into which mankind has fallen. The third chapter considers Blake's use of the serpent and tree image. It is significant that he uses these familiar Christian symbols in various ways which suggest that occult lore and antiquarian mythologies must also be considered in their interpretation. The following five major types of serpent-tree symbolism and Blake's usages are discussed in this chapter: The divine serpent and the tree of life, the serpent as guardian of the tree of life, the serpent as destroyer of the tree of life, the serpent-tempter and the tree of death, and the serpent as an unfaithful messenger of God. It is possible to draw all of these interpretations from Blake's works. By the very diversity of its symbolic associations the serpent provides a unifying factor in Blake. It is in itself a symbol of unity in that it appears consistently in almost all of man's religions and mythologies.
