PARENTAGE STUDIES IN THE BUSHTIT Psaltriparus minimus

Bruce, Jeffrey 11 1900 (has links)
<p> The bushtit (Psaltriparus minimus) of Southeastern Arizona is a cooperative breeder, in which 35% of nests have more than two birds attending. Helpers. join nests at all stages of the breeding season, and potentially make genetic contributions to the nest. Behavioural observations suggest that the fluid social system of the bushtit may provide opportunities for extra-pair fertilizations (EPFs) and intra-specific brood parasitism (ISBP). DNA fingerprinting was applied to assess parentage in the 1988 and 1992 breeding seasons. Using three minisatellite probes (Jeffreys 33.15, 33.6 and PER), fingerprints were generated from nine complete families (nestlings and adults) from 1992 and twelve families of nestlings, in this study, from 1988. Parentage analysis of the 1992 families indicated strict genetic monogamy, despite the fact that two of the breeding groups were socially polyandrous. A case of serial monogamy in a double-brooded nest provided evidence of a male helper achieving reproductive success after aiding in the rearing of non-kin in the first brood. This result suggests the potential reproductive benefits of helping behaviour in a double-brooding species. Genetic relatedness, within groups of nestlings from the same brood, was analyzed in the 1988 samples. In using the 1992 data as a calibration, the 1988 broods were found to contain no unrelated dyads resulting from ISBP. Discrimination between full and half­ sibling relationships was less clear. The analysis of relatedness serves as a useful comparison to other studies that have used a multiple probe approach to assess relatedness. </p> / Thesis / Master of Science (MSc)

Abstract Instant Messenger has become one of the most popular software among juvenile and almost can not be parted from their lives. This research would like to probe deeper into the significance of Messenger in those minority families which are marginalized by the whole society. Therefore, this research takes the minority juvenile, being less social welfare distributed, as the subject, through fundamental interviews of cases, to have an understanding of these juvenile¡¦s using Messenger and Messenger¡¦s significance in their daily lives. This research presents in two ways: one is through story narration providing ample information and clues to achieve an overall understanding; second is to analyze. Aiming at the purpose, divided into the form of relation-establishing and the motive and mechanism of interrelation to analyze the phenomenon of using Messenger. The research finds that these juvenile mostly come from a minority family, such as grand parenting. They lack parental care, get lower grades and cannot get identified by the teachers. As a result, they are depressed in real life. In addition, these juvenile use Messenger in different and distinctive ways from others. Which include : a good means of ¡§calling together¡¨ ¡V to call friends and fellows into group fight; a stealthy way of running away from home ¡V to use Messenger for preparation of running away from home; ¡§group¡¨ ¡V to communicate in an utmost speed; ¡§E generation affaire d¡¦amour¡¨ ¡V Messenger becomes a tool for developing affaire d¡¦amour; a secret means of interconnection; pressure releasing ¡V to release pressure from life through chatting with friends in Messenger; to generate self-identification through using Messenger. For these frustrated juvenile who come from minority families and can not get satisfaction from school and society, Messenger is a bigger inducement. Therefore, the society, their parents and teachers should pay more concern and care to these minority group of juvenile.

O direito de filiação nas famílias contemporâneas / The right to parentage in contemporary families.

Paiano, Daniela Braga 08 June 2016 (has links)
O presente trabalho tem por objetivo analisar o instituto jurídico da filiação nas famílias contemporâneas no Brasil. Para tanto, será contextualizado como está o Direito de Família na atualidade, com as principais alterações que vem sofrendo, como o reconhecimento da união homoafetiva como entidade familiar. Para embasar toda evolução sofrida nesse campo é que se optou por tratar de princípios protetivos do Direito de Família. Desta forma, o ponto de partida deste trabalho será a Constituição Federal de 1988 e o Código Civil de 2002, com as reformas por ele sofridas. Na sequência, serão tratadas as relações de parentesco e de filiação, analisando as espécies de filiação admitidas no ordenamento jurídico pátrio e, ainda, a Resolução do Conselho Federal de Medicina que disciplina as técnicas de reprodução assistida. Ainda neste capítulo será discutido se existe prevalência ou não entre as espécies de filiação admitidas no Código Civil atual e a possibilidade de conhecimento da origem genética autorizada pela lei de adoção. A escolha do tema se deu em razão de, na atualidade, mais especificamente após o ano de 2012, ter sido admitido pela via jurisprudencial, a possibilidade de coexistência de filiação biológica e socioafetiva, sem que uma exclua a outra, originando a denominada multiparentalidade. A jurisprudência, no início, foi reticente com relação à temática, mas em julgados atuais (que são trazidos no corpo deste trabalho) tem sido admitida a multiparentalidade, em especial em casos de adoção, inseminação artificial heteróloga e a filiação socioafetiva ao lado da biológica de forma geral. Assim, analisam-se aqui as formas de reconhecimento e desconstituição da filiação, casos de multiparentalidade em concreto, o conceito do instituto jurídico da multiparentalidade, a possibilidade jurídica de seu reconhecimento no ordenamento pátrio, bem como os efeitos decorrentes de tal admissibilidade. O procedimento metodológico aqui utilizado foi a pesquisa bibliográfica tanto do ordenamento jurídico brasileiro, quanto em alguns ordenamentos estrangeiros. / This research study aims at analyzing the right of parentage in contemporary families in Brazil. In order to do that, Family Law is contextualized nowadays, showing the main changes that it has been going through, such as the recognition of homosexual union as a family. To support the arguments for such an evolution, it has been opted to show some principles concerning Family Law. Hence, the starting point of this study is the Brazilian Federal Constitution of 1988 and the Civil Code of 2002 as well as its reformulations. Subsequently, parenting relation and the right to parentage will be focused on, analyzing the types of parentage admitted in the Brazilian Law. Besides that, this research study will mention the Resolution of Federal Medical Council, which regulates the techniques of assisted reproduction in Brazil. Moreover, in this chapter it shall be discussed the existence or not of any prevalence among the types of parentage currently admitted in the Civil Code and the possibility of knowing the genetic origin permitted by the adoption law. This research topic has been developed due to the fact that nowadays, more specifically after the year of 2012, jurisprudence has admitted the possibility of coexisting both parentage types: the biological and the affective ones, without the exclusion of one of them, which causes the so called multiparenthood. The jurisprudence, at the beginning, was very reticent with regard to this issue, but, in recent decisions (which are carried in this research study) the multiparenthood has been admitted, especially in cases of adoption, heterologous artificial insemination and affective parentage as well as the biological parentage, in general. Thus, the study analyzes ways of recognizing and desconstituting parentage, real cases of multiparenthood, as well as its concept, the possibility of its recognition in the Brazilian Law and the effects that may arise from this admission. The methodological procedure used here was the bibliographic research with regard not only to the Brazilian law, but also to the law of some foreign countries.

Molecular Technologies in the Science and Policy of Florida Largemouth Bass Micropterus floridanus Management in Florida

Sakmar, Josh 01 January 2013 (has links)
Advances in molecular technologies have provided conservation biologist with the opportunity to quantify the genetic structure of a population and, in turn develop management guidelines and policies aimed at preserving the genetic diversity of fish stocks challenged by human activities. This thesis examines the status of genetics as applied to the management of freshwater fisheries by state natural resource agencies with a purpose of understanding the keys to a successful genetics program. An online survey was used to investigate the breadth of molecular marker application to freshwater fisheries management by state natural resource departments. Seven questions were posed to 50 state agencies addressing species of concern, type of genetic resources used, type of molecular marker used, and management concerns. Genetics was listed as a concern in the management of 18 freshwater fish families representing 70 distinct species, with Salmonid species the most frequently reported (20%#37;). A majority of agencies rely on outside resources to perform genetics testing (65%#37;). The most common analysis technique used by state agencies was microsatellite DNA analysis (35%#37;) and the most frequently reported management concerns were genetic stock identification and management boundaries (23%#37;). The application of a specific molecular technology to a conservation question was addressed by investigating the mechanisms of unnatural selection in the form of a study of trait heritability. Microsatellite parentage analysis was used to reconstruct familial relationships of juvenile Florida bass (Micropterus floridanus) displaying variable traits of growth and aggressiveness in a culture setting. Differences in the parentage of high growth and aggression (HGA) and baseline growth and aggression (BGA) offspring showed that certain parent-pairings contribute disproportionally to certain size classes and levels of aggression. These results suggest that the selective pressures of recreational harvest may negatively impact the fitness of wild fish stocks. Overall, this work provides natural resource managers with the basic information required to successfully develop and employ strategies aimed at preserving the genetic integrity of freshwater fisheries.

First Love, Then Marriage, Then a Baby Carriage?

January 2012 (has links)
abstract: Above all else, this project is about parentage in the modern American legal system and culture. Advanced reproductive technologies require our courts to reconsider the long-standing presumption that a child has only one female mother and one male father. We now have children of choice, rather than chance. Assisted Reproductive Technology and its widespread availability and use and changed the landscape of parentage maybe forever. And the children of such efforts remain largely unprotected by our current legal system that favors reproduction by chance within a recognized marriage or at the least, a traditional two-parent paradigm. However, assisted reproduction calls into question the current legal framework for determinations of parentage based in marriage and/or biology. Based on a long and convoluted history, our current legal system conflates marriage and parentage. Moreover, in many circumstances the law restricts both the number and gender of the parties to a marriage or possible parents. One of the more compelling historical and still salient justifications for doing so is to accord the "Best Interest of the Child" standard which purports to underpin all such determinations. Unfortunately, that standard cannot best be met when weighed in a balance against a constitutionally protected exclusive right to parent vested in an adult either by a determination of a genetic link to the child or marriage to another parent. Children of choice, who result from the affirmative and purposive engagement in assisted reproduction, should be entitled to the same protections as children of chance born to a man and woman who are married. Once we look beyond marriage and biology as determiners of parentage, a better way for our legal system to serve the best interests of children, and their parents, is to identify and protect those adult relationships that are parental in nature and that benefit the child irrespective of a marriage between parents or genetic links to the child. Fortunately, the tools to accomplish this paradigm shift already are in existence. The expansion of our commonly used definitions and broader view of our current statutes will allow the legal system to better protect both children of choice and children of chance by making better parentage determinations. To that end, this project also takes on the ambitious task of praxis; of applying the theories to the law as it stands and demonstrating how the new paradigm might look as it is implemented with all of its far-reaching tentacles. / Dissertation/Thesis / Ph.D. Justice Studies 2012
