Learning novel concepts from relational databases is an important problem with applications in several disciplines, such as data management, natural language processing, and bioinformatics. For a learning algorithm to be effective, the input data should be clean and in some desired representation. However, real-world data is usually heterogeneous – the...
We develop a methodological approach using splines to analyze the deterministic population dynamics of fish stocks at low stock levels. Considering the aggregate Northern cod stock by way of illustration, we reject the hypothesis of strong compensation estimated by the conventional regression methods used by classic bioeconomic models.
This work is part of the SUCCESS project (Work Package 4: Competitiveness and sustainability of European fisheries and Aquaculture sectors) funded by the EC (H2020, GA 635188). The dynamics of the value chain in eight different species at the Spanish market has been studied using price integration methodologies. Cases of...
The aim of this work is to analyse the evolution of profit margins of those firms that have decided to use a PDO label (Mejillón de Galicia in the case of this research) to improve their economic performance and to evaluate the success of this product differentiation strategy. A sample of...
European seabass and gilthead seabream are two economically important cultured fish species along the Mediterranean coast. Both species represent respectively 10.9% and 13.5% of the total value of the European aquaculture sector (Eurostat, 2013). The EU is one of the largest producers of seabass and seabream in the world, being...

The extent of lipid hydrolysis (free fatty acids) and oxidation...
Understanding the interplay between energy and water is central to effective natural resource management. With enough energy it is possible to secure sufficient water, with enough water it is possible to produce nearly boundless energy. The sun is the engine which drives the availability of both these resources; nearly every...
This study examined water scarcity and vulnerability in Quintana Roo, along the northern Caribbean coast of Mexico where rapid growth of tourism in the past 40 years has limited the ability of rural and urban communities to obtain safe, reliable, and equitable access to water services and critical water infrastructure...
Latinos are the largest and most rapidly growing ethnic minority in the United States, and they have the highest dropout rates of any major ethnic group in the country (U.S. Department of Labor, 2003). Latinos' educational attainment is consistently lower than that of other students (Gandara, 2008). The majority of...
Concerns regarding maintaining wheat yield per hectare and extending
the commercial life expectancy of cultivars grown in the Yaqui
Valley of Mexico prompted this investigation. Four genetically diverse
spring wheat cultivars were grown in pure stands and in all possible
combinations at the Northwest Agricultural Research Center at Ciudad

Until the 1930s, flows of the Colorado River maintained approximately 781,060 hectares of wetlands in its delta. These wetlands provided important feeding and nesting grounds for resident and migratory birds as well as spawning and protection habitat for many fish and other invertebrate species. However, the Delta's wetlands started to...
Fisheries management currently claims for fisheries governance (FG), a more balanced scheme that proposes to share the power among government, civil society and economics. In Mexico and other developing countries, the lack of operational regulations has delayed its implementation. Several authors state that topological analysis is useful to identify key...
Seascape ecology is an emerging discipline focused on understanding how features of the marine habitat influence the
spatial distribution of marine species. However, there is still a gap in the development of concepts and techniques for its
application in the marine pelagic realm, where there are no clear boundaries delimitating...

Over the past century, the tuna canning industry has been dominated by a few big companies, some of
them having changed of ownership or merged: these oligopolistic firms are the “big three” in the USA,
Van Camp, Star Kist, and Bumble Bee, the French Saupiquet, the Italian Trinity Alimentari and...
The focus of this thesis is to design, characterize, and apply novel computational methods and molecular systems to interrogate heterogeneous human gut microbiome-related phenomena. In Chapter 2, I design, implement, and characterize a method for embedding co-occurrence patterns derived from massive 16s amplicon datasets. I use this method to 1....
Rising atmospheric [CO₂], cₐ, is expected to affect stomatal regulation of leaf gas-exchange of woody plants, thus influencing energy fluxes as well as carbon (C), water, and nutrient cycling of forests. Researchers have proposed various strategies for stomatal regulation of leaf gas-exchange that include maintaining a constant leaf internal [CO₂],...
Court cases, wills, and letters are common examples of surviving primary texts
from colonial Latin America. These documents are important to historians because they
provide a unique glimpse into the lives of ordinary people who lived hundreds of years
ago. This thesis is a recreation of these types of primary...

Literacy is often considered to be a basic set of skills to be mastered by the student; the conventional wisdom maintains that the individual who has mastered these skills is then literate. Scholars in the field of literacy studies, however, argue that such assumptions about literacy fail to take into...
It has generally been assumed by historians and anthropologists that the indigenous groups living to the west and northwest of the Colorado River were non-horticultural with three or four exceptions: some horticulture among the eastern-most Kamia, among the Chemehuevi who settled at a late date along the Colorado River, and...
The concept of compensatory mitigation is well established as an approach to environmental management. In the past, mitigation programs have been used to conserve wetlands affected by development, and is proposed as a cost-effective approach to offsetting greenhouse gas emissions through reforestation programs. The concept may be equally applicable to...

Members of the family Chlamydiae cause a wide range of diseases. Chlamydia trachomatis and C. pneumoniae are most commonly associated with human disease. C. psittaci and C. pecorum are largely animal pathogens, although C. psittaci can cause pneumonia in the elderly and immunocompromised. A vaccine against these pathogens is desirable,...
This thesis is a comparative study of the two processes of currency change that occurred in Ecuador in 2000 and in France in 2002. Although the background of these two countries and the motivations behind each currency change varied, Ecuador and France have experienced many similar outcomes. Each of the...
Small-scale fisheries around the world are increasingly facing pressures from a range of environmental, economic, and social sources. In order to sustain the societal benefits of small-scale fisheries, it is imperative to understand how fishing communities adapt to disturbances. Fishermen often catch multiple different species as an adaptation technique because...
This thesis is comprised of two manuscripts based on a laboratory experiment conducted to examine realistic wave forcing on a vertical wall subjected to tsunami loading. The first manuscript examined tsunami force and pressure distributions on a rigid wall that was fronted by a small seawall. Six different seawall heights...
The yeast Brettanomyces bruxellensis is the most important wines spoilage yeast encountered during winemaking as it can survive in wine for long periods, requires minimal nutrients for growth, and can be difficult to control. Brettanomyces produces two major spoilage products, the volatile phenols 4-ethylphenol (Band-Aid, medicinal smell) and 4-ethylguaiacol (smoke,...
The original settlement of Santa Rosalia,
Baja California del Sur, Mexico, was due to the exploitation
of the copper resources in the Boleo copper
district of Mexico. Mineral resources have always
