The ecology and feeding behavior of mosquitoes in the Galapagos Islands

Mosquitoes remain important vectors in transmitting wildlife diseases. This dissertation aims to understand the role that mosquitoes play in transmitting wildlife diseases such as avian malaria, a protozoan parasite belonging to the genus Plasmodium. Using data from wild-caught mosquitoes captured in multiple years and across multiple islands on the Galapagos Archipelago, we describe distributional patterns of mosquitoes, their range limits and assess whether there exists a disease-free refuge as occurs in Hawaii. We show that altitudinal ranges for disease transmission of avian malaria may not be bounded by a stable disease-free refuge, since mosquitoes are found at all elevations, and the highest peaks are significantly lower in Galapagos than in Hawaii. Secondly, we investigate the influence of ecological factors on the distribution and abundance of mosquitoes on the inhabited island of Isla Santa Cruz. We show that both Aedes taeniorhynchus and Culex quinquefasciatus, two of the three mosquito species found in Galapagos, decline with elevation. We also show the influence of statistically significant factors of elevation, temperature, and humidity on mosquitoes in Galapagos. This chapter discusses the ecological requirements of the avian malarial parasite and how this may influence disease dynamics in the Galapagos; sampling sites at all elevations were within the optimal temperature range for both mosquito and parasite development. Thirdly, using data from wild-caught mosquitoes from Santa Cruz, we discuss the feeding range of both A. taeniorhynchus and C. quinquefasciatus. This chapter takes a molecular approach in screening mosquito bloodmeals using vertebrate universal primers. Fourthly, we use a combination of field captured mosquitoes, molecular screening, and microscopy in identifying Plasmodium parasites and understanding their competence in the disease dynamics of avian malaria in Galapagos. Collectively, these results aim to guide conservation efforts towards managing disease-transmitting mosquito vectors in Galapagos

Una mirada al mundo de lost : análisis de los elementos de la narrativa audiovisual de la serie que han influenciado culturalmente en la audiencia y su aporte a los shows de su género

Por medio de esta investigación se pretende desarrollar un análisis de la serie de televisión norteamericana LOST, a partir de una definición de las estructuras narrativas, argumentación, la temática, los personajes, el proceso de producción, los recursos literarios y las referencias culturales que han permitido que esta serie se configure como un hito de la televisión por el impacto que ha tenido en su audiencia. Para llevar a cabo el presente estudio, se hace necesario dividir el análisis en 5 capítulos que delimiten las áreas esenciales donde se centrará la investigación: Historia, Aspectos Técnicos Audiovisuales, Técnicas Narrativas, Recursos Literarios y Referentes Culturales. Teniendo en cuenta estos ejes, el presente Trabajo de Grado se centrará en responder la siguiente pregunta de investigación: ¿Cúales son los aspectos técnicos, narrativos, culturales, literarios y cinematográficos que dan forma a la historia de LOST y que constituyen un aporte en la forma de desarrollar nuevas formas de hacer televisión?Incluye bibliografí
