RNA silencing is an evolutionarily conserved system that
functions as an antiviral mechanism in higher plants and
insects. To counteract RNA silencing, viruses express
silencing suppressors that interfere with both siRNA- and
microRNA-guided silencing pathways. We used comparative
in vitro and in vivo approaches to analyse the molecular
mechanism of...
To date, the use of oceanographic data in fisheries management has been limited by the scarcity and the difficulty of accessing complete oceanographic datasets. Consequently, fish stocks are managed with limited knowledge about the habitat where fish live and incomplete understanding of what oceanographic conditions affect their populations. With the...
This study was undertaken to see if a method of handling
segregating populations could be employed which combined the positive
attributes of the traditional pedigree and-bulk methods. Derived F₅
lines from the pedigree, bulk, and what is identified as a modified
bulk method, were obtained from three winter wheat crosses....
This document partially addresses the Wetlands component of San Juan County’s Critical Areas Ordinance (CAO). Drawing from a foundation in best available science, it describes important functions performed by the County's wetlands, effects of various activities on those functions, and strategies for protecting wetland functions from impacting activities, with an...
This document provides definitions and a general overview of streams and lakes of San Juan County (SJC) and then describes impacts to these water bodies and strategies for determining widths of buffers that protect their functions. It similarly provides definitions and a general overview of SJC upland (terrestrial) habitats, describes...
In the wake of the ``third wave'' of democratization, scholars and practitioners were optimistic regarding the ease with which countries could adopt democratic norms and institutions. However, after four decades of democracy, many competitive regimes have not improved government probity or developed strong forms of accountability. Levels of economic and...
The research was conducted in the Fundo Almendra, property of the National University of the Peruvian Amazon (UNAP). The objective was to analyze the gross forest loss in the period 2001-2021 in Fundo Almendra, the relationship between forest loss and local surface temperature, and the role of local communities’ demographics...
Disturbance and microclimate interact to play a central role influencing the composition and structure of plant communities. In this thesis, I examined plant community composition and structure twenty years after high severity wildfires with and without post-fire management (salvage logging, fuel treatment, tree planting, and shrub release) under contrasting microclimatic...
Large “hypercarnivorous” felids are recognized for their role as apex predators and hence as key elements in food webs and ecosystem functioning through competition and depredation. Here we show that cougars (Puma concolor), one of the largest and the most widely ranging apex felid predators with a strictly carnivorous diet,...
This ethnomusicological study has examined the forces that have globalized the Andean instrument of the quena and the genre of Andean music as a whole. This thesis specifically addresses the cultural, and socio-political factors over the last century that has led to the quena being circulated across the globe. Much...
