Population control programs such as family planning and the introduction of sex identification technologies has helped to create skewed sex ratios in northern India and particularly in the state of Haryana. Due to a surplus of men and the numbers of missing females, an organized business of bride trafficking has emerged where poor women from eastern and northeastern states of India are bought and brought to Haryana for the purpose of marriage. This thesis explores how skewed sex ratios have contributed to the phenomenon of bride trafficking in Haryana guided by the theoretical framework of violences of development which argues that there is a hidden paradox within development. This was done by conducting a conventional content analysis in order to create a deeper understanding of the phenomenon. There is scarce research on bride trafficking, therefore this study contributes with extended knowledge in order to shed a light on the increasing trade with females.

Chionochloa, a genus of snow tussock grasses native to New Zealand, exhibits pronounced mast seeding. Chionochloa suffers very high levels of pre-dispersal flower and seed predation by three main insects: Eucalyptodiplosis chionochloae, a cecidomyiid midge, which is formally described here; Megacraspedus calamogonus, a gelechiid moth and Diplotoxa similis, a chloropid fly. Seven species of parasitoids that attack these seed predators were discovered. Four species parasitize M. calamogonus (one tachinid fly and three hymenopteran wasps), one parasitizes D. similis (Hymenoptera: Eulophidae) and two parasitize E. chionochloae, (a pteromalid wasp Gastrancistrus sp. and a platygastrid wasp Zelostemma chionochloae, which is given a formal description here). The abundance, predation levels by each of the insect species, and interactions between all the organisms in the community were studied across three elevations at Mount Hutt over three summer seasons. M. calamogonus was most abundant at 450 m altitude during all three seasons. D. similis was most common at 1070 m altitude, while its predation levels peaked in low flowering seasons and decreased in high seasons. E. chionochloae was abundant in all three altitudes and increased its predation levels with increasing flowering intensity. E. chionochloae was confirmed to use prolonged diapause of at least three years. Prolonged diapause was also confirmed in its two parasitoids. Chionochloa plants were manipulated with various treatments to test the effect on diapause in E. chionochloae and its two parasitoids. Treatments included plant warming, root pruning, gibberellic acid sprayed on the plants and combinations of these treatments. All three insects changed their emergence in response to some treatments and therefore it was suggested that combined with risk-spreading diapause, they may use some predicting to emerge from prolonged diapause. E. chionochloae control their diapause following some of the cues that Chionochloa use for flowering, while Z. chionochloae and Gastrancistrus in some cases follow their host’s cues and in others use similar cues as Chionochloa plants. Emergence or diapause predictions differed across elevations and plant species in all three insect seed/flower predators. E. chionochloae had female-biased sex ratios in different populations even after prolonged diapause. There was week evidence that both parasitoid species are female-biased in the first emergence year and male-biased after more than one year in diapause. Therefore it was suggested that diapause is not more costly for females of E. chionochloae and its parasitoid than for males. Females of all three species were not found to be better predictors (i.e, more likely to respond to treatments by not entering extended diapause) than males. The complex interactions of all the organisms in this web are thought to be sensitive to climate, and it was suggested that the global climate change may alter this sensitive system.

This thesis sheds light on several aspects of the economics of marital formation, dissolution, and bargaining. The first chapter focuses on the relationship between divorce law and family wellbeing, and shows that lowering the cost of divorce can reduce spousal conflict. The second chapter analyzes the effects of property division laws upon divorce on marital instability and female labor supply. Results suggest that a redistribution of property rights over family assets in case of divorce towards the financially weaker spouse, usually the wife, may increase marital instability and reduce female labor supply. The third chapter examines the role of sex ratios in college in explaining family formation patterns of young adults. Empirical evidence suggests that individuals who are exposed to a larger fraction of opposite-sex school mates are more likely to be married or residing with a partner from the same field of study shortly after finishing school. / Esta tesis arroja luz sobre algunos aspectos de la economía de la formación, disolución y negociación familiar. El primer capítulo se centra en la relación entre la regulación sobre el divorcio y el bienestar de la familia, y muestra que una disminución del coste del divorcio puede reducir el nivel de conflicto entre esposos. El segundo capítulo analiza los efectos de las leyes de división de activos en caso de divorcio sobre la inestabilidad matrimonial y la oferta de trabajo de las mujeres. Los resultados sugieren que una redistribución de los derechos de propiedad sobre los activos familiares en caso de divorcio en favor de la parte financieramente más débil, habitualmente la mujer, puede aumentar la inestabilidad matrimonial y reducir la oferta de trabajo de las mujeres. El tercer capítulo examina el papel de la ratio de sexos en la universidad en explicar el patrón de formación familiar de adultos jóvenes. La evidencia empírica sugiere que los individuos que están expuestos a una mayor proporción de compañeros del sexo opuesto durante la universidad tienen más probabilidad de estar casados o residiendo con una pareja de la misma carrera, poco después de finalizar los estudios.

Sex determination in leatherback sea turtles is directed primarily by the temperatures a clutch experiences during the middle third of development. Warmer temperatures tend to produce females will cooler temperatures yield males. Nest temperatures can vary spatially and temporally. During the 2010 and 2011 nesting seasons, this study estimated the hatchling sex ratio of leatherback sea turtles on Sandy Point National Wildlife Refuge (SPNWR), St. Croix, U.S. Virgin Islands. I measured sand temperatures from May- August and across the spatial range of leatherback nesting habitat. I spatially interpolated those temperatures to create maps that predicted temperatures for all nests incubating on SPWNR. Nest temperatures were also directly measured and compared with predicted nest temperatures to validate the prediction model. Sexes of dead-in-nest hatchlings and full term embryos were used to confirm the sex-temperature response. The model showed that microclimatic variation likely impacts the production of both sexes on SPNWR. / Includes bibliography. / Thesis (M.S.)--Florida Atlantic University, 2013.
