Desenvolvimento e utilização de marcadores microssatŠélites em perdizes (Rhynchotus rufescens) e outros Tinam‰ídeos /

Santos, Dimas Oliveira. January 2011 (has links)
Orientador: Humberto Tonhati / Coorientador: Renato Caparroz / Banca: Marcelo Cervini / Banca Leonardo de Oliveira Seno / Banca: Sandra Aidar de Queiroz / Banca: José Maurí‰cio Barbanti Duarte / Resumo: A Universidade Estadual Paulista - UNESP, campus de Jaboticabal desenvolve há v†ários anos pesquisas na á†rea de animais silvestres, contribuindo dessa forma na conservaçãˆo e produção‡ de espŠécies amea‡çadas de extin‡ção. Uma dessas espéŠcies estudadas para fins cientí‰ficos, a perdiz (Rhynchotus rufescens), apresenta potencialidades para a produ‡ção comercial em cativeiro. Com o objetivo de determinar polimorfismos genéŠticos nessa espéŠcie e em outras espéŠcies de tinam‰ídeos, foram desenvolvidos 16 pares de primers de microssatéŠlite para a perdiz a partir de biblioteca gen“ômica enriquecida com microssatŠélites. A fim de se verificar a amplificação cruzada em perdiz e em outros tinam‰ídeos foram utilizados 10 pares de primers desenvolvidos para avestruzes (Struthio camelus) e outros 10 pares desenvolvidos para o inhambŒú-da-cabe‡ça-vermelha (Tinamus major). Dos 16 locos desenvolvidos para perdiz, 8 apresentaram sucesso na amplificação nessa espŠécie e apenas cinco amplificaram em outros tinamídeos. Foi realizada a genotipagem em 26 amostras de perdizes e obtidas estimativas relacionadas ao percentual de locos polimó‹rficos (50%), núŒmero mŠédio de alelos por loco (5,75), conteŒúdo polim‹órfico informativo mŠédio (0,62) e diversidade genéŠtica esperada (0,69). Quanto ao teste de transferabilidade, dos pares de primers desenvolvidos para T. major, somente um apresentou amplificação especí‰fica em perdizes, sendo observadas taxas de amplificação cruzada de 100 e 70% para macuco (Tinamus solitarius) e para a azulona (Tinamus tao), respectivamente. As amplificações nos demais tinamí‰deos ficaram restritas a cinco locos de microssatŠélites. Com o uso de programas computacionais e de...

One of these species is the red-winged-tinamou (Rhynchotus rufescens), that has potential for production in captivity. The aim of the study was to determine genetic microsatellite polymorphisms in this species and other tinamous species. Sixteen microsatellite primer pairs were developed for the red-winged-tinamou from a genomic library enriched with microsatellites. In order to verify the cross amplification for the tinamous species we used 10 pairs of primers designed for ostriches (Struthio camelus) and 10 pairs developed for Tinamus major. From the 16 loci developed for red-winged-tinamou, 8 amplified in this species and only five amplified in other Tinamous. Genotyping was performed on 26 samples and estimates related to the percentage of polymorphic loci (50%), average number of alleles per locus (5.75), polymorphic information content (average 0.62) and expected genetic diversity (0.69). In order to test the transferability of the primer pairs developed for T. major, only one had a specific amplification in partridges, with observed rates of crossamplification of 100 and 70% for macuco (Tinamus solitarius) and the azulona (Tinamus tao), respectively. The amplifications in other tinamous were restricted to five microsatellite loci. With the use of computer programs and statistical analysis, we estimated genetic and phenotypic parameters of morphometric characteristics in red-winged-tinamou, in order to...

Phylogenetic analysis of the Nearctic Blepharicera Macquart (Diptera: Blephariceridae) with an emphasis on the eastern Blepharicera tenuipes group Hogue

Jacobson, Amanda Jane 01 December 2010 (has links)
The eastern Nearctic fauna of Blepharicera Macquart (Diptera: Blephariceridae) is revised to include twenty-three species, six of which are new to science. Descriptions of the larvae, pupae, and adults of B. amnicula n. sp., B. conifera n. sp., B. crista n. sp., B. enoristera n. sp., B. hillabee n. sp., and B. opistera n. sp. are presented. Keys to instar IV larvae, pupae, and adults of all eastern Blepharicera (except B. caudata Courtney) are provided. Phylogenetic studies were conducted to determine the relationships between eastern and western Nearctic Blepharicera and among species within these groups. Larvae, pupae, and adults were available for all known Nearctic species except B. caudata and B. micheneri Alexander. Molecular data acquired from two genes and morphological data for 44 characters were used to test previous phylogenetic hypotheses on the historical relationships and biogeography of Nearctic Blepharicera. Analyses using maximum parsimony, maximum likelihood, and Bayesian inference were conducted. Resulting phylogenies support monophyly of the B. tenuipes and B. micheneri groups and suggest that multiple species complexes may exist within the B. tenuipes group.

Sexual selection and delayed plumage maturation in the sub-adult male cohort of the red-winged blackbird (Agelaius phoeniceus)

Greenwood, Hamilton. January 1985 (has links)
The variable plumage characteristics of the sub-adult male cohort of the red-winged blackbird (Agelaius phoeniceus) are described. At one extreme of the plumage variation, there are a group of sub-adult males that are indistinguishable from the adult males. These birds can only be correctly aged by cloacal examination for the bursa of Fabricius in the autumn. At the other extreme, approximately 4% of the population are near perfect female-mimics. A simple scoring system based on the interspersion of dark feathers in the epaulet is presented, which permits classification of the sub-adult males into 1 of 6 plumage classes. These epaulet classes are significantly correlated with other traits of the plumage. / Age when entering the prebasic molt, and the physical condition of the sub-adult male may influence the development of the varied plumage characteristics. / The distribution of the plumage characteristics of a population of sub-adult males collected at a major blackbird roost in the province of Quebec is described for birds captured in the fall and spring. The spring plumage characteristics are more variable than the fall, a phenomenon which is not consistent with plumage wear as has been previously reported, but which may be related to a prealternate molt which the birds undergo. The prealternate molt is prevalent in some but not all of the contour feather tracts, and is restricted to females and the sub-adult male cohorts. / An age- and sex-specific spring migration of red-winged blackbirds is examined. Adult males arrive to the spring roosts first, followed by yearling males and then females. A similar pattern of dispersal to the breeding territories is described. Within the subadult male cohort, the birds with the most adult-male like plumage traits arrive at the vernal roosts first. / The characteristics of the prealternate molt and differential spring migration are discussed in relation to the pressures of sexual selection on the respective age and sex cohorts. / The adaptive significance of variable sub-adult male plumages and delayed plumage maturation in passerines is evaluated. Several competing hypotheses have been advanced to describe the phenomenon of delayed plumage maturation. These hypotheses are reviewed, and a test is proposed which unequivocally differentiates between the various alternatives. (Abstract shortened with permission of author.)
