Full textAbstract:
A study of the Helminthoglyptidae of Sonora was undertaken to determine the extent of their distribution and speciation. As a result, nine new species of Sonorella are described, and new ranges of the known species are given. The status of the family is reviewed and its standing is supported with the analysis of morphological characteristics of several genera. The zoogeography of the family and its distribution are shown. Possible dispersal and isolation mechanisms are discussed in order to explain the present distribution of these snails, and comments on ecological and speciation accounts are offered.

The purpose of this study was to validate the Adlerian Parenting Educational Model (APEM) as a means of improving parent-child relationships in urban, Mexican families as measured by the movement toward the development of willingness to contribute and cooperate by family members. Research problems and their corresponding hypotheses were formulated to facilitate the validation of the model. The subjects were 42 mothers whose children attended a preschool program in the geographical area of Caborca, Sonora, Mexico. Each subject was actively committed and willing to participate in the APEM. The study utilized a pretest-posttest control group design to obtain an indication of mothers' development of positive changes in their child's behavior and effectiveness in allowing their children to make more positive changes in their behavior as measured by the Social Interest Index, the Adlerian Parental Assessment of Child Behavior Scale, and the Behavior Concepts Inventory: Educational Model. All subjects were administered each instrument prior to the first session to determine their degree of social interest, understanding of Adlerian principles, and potential behavioral areas for mother and children to work with. The two methods of analysis employed, a test of differences between means and a test of homogeneity of variance, revealed that mothers in the treatment group of this program experienced more positive interpersonal relationships among family members, a more positive attitude toward themselves, positive changes in their perceptions of their child's behavior, a more thorough understanding of Adlerian principles, and related more positively to their children than mothers in a control group. The study presented a number of implications for further research and indicate that the APEM may be applied to different groups.

Full textAbstract:
A taxonomic revision of the Bulimulidae of Sonora, Mexico is undertaken. The existing species are redescribed and their ranges given. Four new species are described and one species synonymized on the basis of anatomical and conchological characteristics. In addition a new genus, Drymaeus Albers, 1850, is recorded for the state and several species are reassigned from Rabdotus Albers, 1850 to Naesiotus Albers, 1850. The zoogeography of the Sonoran species and genera is also presented along with their relationships to congenerics in the rest of North America. It was determined that one of these genera Naesiotus has a North American-South American disjunct distribution and that both it and Rabdotus probably had Southern Hemisphere origins. The mechanisms of isolation and dispersal are discussed and a microplate tectonics model is presented to explain them. The Gondwanaland distribution of the subfamily is also described.

Full textAbstract:
Assemblages of Paleozoic age and less significant Triassic and possibly Cretaceous-Tertiary volcanic rocks constitute the Sierra El Aliso, 186 km east-southeast of Hermosillo, Sonora. The Paleozoic section consists of approximately 2000 m of allochthonous Ordovician to Permian pelagic and hemipelagic deposits that accumulated in continental slope, continental rise and ocean floor (?) environments. The lower Paleozoic is characterized by graptolitic black shale and radiolarian chert, quartzite, argillite and local limestone. The upper Paleozoic is predominantly turbidite carbonates rich in benthonic foraminifera, and conodont faunas, subordinate bedded chert, siltstone, sandstone and chert-clast conglomerate. After Early Permian time, but prior to the deposition of the Late Triassic Barranca Group the Paleozoic section was imbricated along south-southeast vergent thrust faults. The Triassic rocks unconformably overlie the Paleo-zoic strata and all thrust faults. The Triassic and older rocks are overlain by the Cretaceous-Tertiary volcanics.

Full textAbstract:
This thesis reports the findings of a multi-disciplinary investigation focused on exploring the Paleoindian habitation of the upper San Pedro Valley, Sonora, Mexico. Two recently-identified fluted points stand as the first Clovis evidence reported from the project area, and site AZ:EE:16:5 (ASM/INAH) has the potential of containing intact Clovis archaeology. Several lanceolate points of the Plainview variety mark the first late Paleoindian evidence reported from Northern Sonora. Four newly identified lithic sources may inform our understanding of Paleoindian range and mobility in the valley and Greater Southwest region. However, intensive geochronological determinations demonstrate that terminal Pleistocene and early Holocene alluvial deposits are rare or absent throughout most of the basin in Mexico. The findings of the project indicate that well-known Paleoindian-age deposits identified at Clovis sites in the valley in Arizona are restricted to relatively small areas of the upper basin north of the border.

Full textAbstract:
Cnemidophorus costatus barrancorum was studied in the short-tree forest of southeastern Sonora, Mexico from November 1985 to December 1988. Adult females varied in snout-vent length from 71 to 101 mm, while males reached a maximum of 121mm. Ontogenetic change in color-pattern was pronounced, however sexual dimorphism in color-pattern was slight. The mean number of dorsal scales around mid-body was 99.4. Mating occurred in late July. Females laid two clutches of eggs per season, with clutch size varying from 2-8 (X = 4.2). The maximum shelled egg dimensions were 10.5mm x 15.6mm. Hatchlings appeared in early fall, and were surface-active throughout November. Yearlings emerged from hibernation in February-March. Adults were active from mid-spring into September. C. c. barrancorum had a unimodal daily activity pattern, with activity beginning when air temperature exceeded 30°C. The mean body temperature of surface-active animals was 40.0°C.

Full textAbstract:
Puerto Penasco is a small Mexican town (pop. 26,141) located on the Sonora coast 65 miles from the U.S. border at Lukeville, Arizona. In recent years, over-fishing in the Gulf of California has resulted in a sharp decline in Puerto Penasco's fishing industry. Tourism is an economic alternative which holds potential for revitalizing the local economy, if planning and design for tourism is carefully conceived and executed. Review of international tourism and examination of economic, socio-cultural, and environmental impacts of tourism indicate that traditional forms of large-scale mass tourism may not be appropriate for Puerto Penasco. An alternative, integrated form of tourism is proposed for Puerto Penasco that respects local landscapes as well as local culture and heritage. Revitalization of the historic Old Town and the Harbor areas is proposed to attract tourists to existing urban areas while preserving natural open space along the coast.

Full textAbstract:
The current study examines the stratigraphy, geochronology, and paleoecology of La Playa, an Early Agricultural period archaeological site (3600-1800 BP) located in northern Sonora, Mexico. We distinguished seven stratigraphic units ranging in age from >44,570 to 680 cal yr BP. All of the cultural remains are contained in Unit B, which spans from 4700-1580 BP. Deposits from Unit B represent overbank deposition from the nearby Rio Boquillas. The majority of cultural materials come from Units B4 and B5, which correspond to the Cienega phase (2800-1800 BP) of the Early Agricultural period. This period coincides with the first sedentary agricultural populations in the region and is marked by thousands of archaeological features including roasting pits, human burials, and extensive canal systems at La Playa. The presence of semi-aquatic and aquatic snails demonstrates that water was present year round in the canal system. The stable and radiometric isotopic evidence suggests that the early agriculturalists diverted ground water, likely from the nearby Rio Boquillas. Cultural remains from Unit C spanning the period <1580-680 BP are rare, suggesting major population decline during this time. There is little to no evidence of bioturbation in Unit C, suggesting that the landscape was thinly vegetated at this time. La Playa has experienced up to five meters of erosion during historic times, exposing a complex alluvial stratigraphy and numerous cultural features, which has greatly complicated archaeological interpretations at the site.

Full textAbstract:
The archaeological record of the first Americans in Mexico is poorly known and somewhat confusing. However, the state of Sonora presents a remarkably pristine setting for studying the late Pleistocene occupation of North America. The early archaeological record in Sonora is stunning in terms of its relative abundance and only within the past ten years has this fact become evident. The Paleo-Indian sites are concentrated in north-central Sonora on and surrounding, the Llanos de Hermosillo. The settlement pattern appears to indicate that Clovis groups were generalized hunter and gatherers that exploited a wide range of environments, and their diet was based upon a wide variety of foodstuffs. The Clovis groups of Sonora developed a sophisticated settlement pattern and land use determined by the location of lithic sources for tool making, water sources, large prey animals and a mosaic of edible plants and small animals. Exploiting an extensive territory probably permitted them to remain in the same region for longer periods of time. The presence of only few late Paleo-Indian diagnostic points could represent the decrease of population density in Sonora, but most likely it is an indication that after Clovis a regionalization of the hunter and gather groups took place in Sonora. The Sonoran Clovis occupation is a testimony that multiple regional Clovis adaptations emerged each with specific responses of plants, animals and resources.

Full textAbstract:
Nogales, Sonora, is one of many cities along the international border between Mexico and the United States, and the most important border crossing for the state of Sonora. Although each of them unique, they have similar problems as a result of the accelerated economic and demographic growth, such as high migration rate, frantic activities downtown, and overwhelming traffic. These cities must act before they become larger cities with serious health, environmental and social issues; they need to boost up their economy in order to become destination points. A general condition in Nogales, Sonora is the location of downtown within the fi rst blocks south of the border. Many agencies are ‘fitted’ into pre-existing buildings, making them deficient in interior, exterior and parking space, as well as character and status. Commercial establishments and “tourist” attractions are also located here. This overloading range of ongoing activities causes them to interfere with each other. The recommendation is to remove government buildings from downtown and group them together. This effort intends to relieve the entanglement of activities in the area, allowing for commercial services and tourist activities to flourish, helping the city’s economy. Additionally, reducing the traffic flow in the first few blocks south of the border will offer a safer and more appealing entrance to Sonora from the U.S. Relocating government agencies away from downtown hopes as well to remove the flow of users (and traffic) generated by them. There is an effort to group government agencies together away from downtown The developers (private sector) of a projected Urban Center, located on the rapidly developing south part of the city, are donating 15 hectares within the area known as “El Greco” (the Greek in Spanish) destined for creation of a Civic Center. The city is lacking of character and sense of pride. The grouping of the government agencies in a well planned assemble could provide the government with a strong image and respect. This report proposes the development of design guidelines for a new Civic Center in the city of Nogales, Sonora, Mexico, that may be applicable to other Mexican cities along the northern border with the U.S. These design guidelines will facilitate the development of the Civic Center, as an integral part of the Urban Center, as well as of the city itself. This report culminates in the creation of a prototype Master Plan for the proposed site applying the design guidelines resulting from the research. Introducing Landscape Architecture principles hopes to sensitize and educate a culture that is unaware of the potential and benefits of this discipline. The document will provide a Landscape Architecture approach towards exterior space; specifically within a government building assemble.

Full textAbstract:
A marked population of wintering Gray Vireos (Vireo vicinior) was studied for two seasons (1985-1986 and 1986-1987) on two study sites near Puerto Lobos, Sonora, Mexico. Eleven of the 15 individuals banded in the first winter returned to the same areas in the following winter. Territories were defended throughout the winter and averaged 0.9 ha in size (N = 9). Territorial interactions occurred frequently along boundaries as neighbors trespassed to forage on each others' territories. All birds appeared to defend individual territories. First year birds appeared to occupy marginal territories on the periphery of the best habitats. Fruit from the elephant tree, Bursera microphylla, became a dominant part of the vireo's diet as winter progressed and the fruit ripened. The importance of B. microphylla to the vireos' winter diet and the high degree of overlap between the winter range of the vireos and the distribution of the plant suggested a mutualistic interaction between them. Gray Vireos acted as the primary dispersers for the plant.

Full textAbstract:
Piedras Verdes is a supergene-enriched porphyry-copper deposit. It contains 290 Mt at a total copper grade of 0.37%. The average thickness of the chalcocite blanket is 110 m. It is 400-500 m wide in a north-south direction and approximately 4 km long. The oxide-sulfide interface ranges from 80 m to 340 m in depth. The country rocks are a Triassic-Jurassic or Paleozoic meta-sedimentary sequence and a Tertiary intrusive porphyry suite. Geochemical studies define six principal intrusive phases of volcanic arc affinity, from quartz monzodiorite to granodiorite in composition. The first magmatic event at Piedras Verdes, was the emplacement of the Sinaloa-Sonora batholith at 67.3 ± 1.4 Ma. This was followed by the emplacement of quartz monzodiorite, "tall" biotite granodiorite, quartz-feldspar and biotite-hornblende granodiorite porphyries, fractionated from a less evolved magma than the preceding batholith. The latest magmatic activity at Piedras Verdes originated andesitic dikes (48.4 ± 1.2 Ma). Mineragraphic studies indicate three mineralizing pulses. A first pulse, related to emplacement of the batholith and the quartz monzodiorite, produced skarns. The second event was associated with the "tall" biotite granodiorite porphyry, introducing sulfides. The third pulse, related to the quartz-feldspar porphyry introduced quartz-molybdenite-chalcopyrite veins. Neodymium isotopic analyses, indicate that the four main intrusive phases at Piedras Verdes were formed by a mixture of primitive and crustal materials. Re-Os isotopic analyses on sulfides yield no considerable amount of Re. It is assumed that the sulfides suffered Re loss during alteration after primary mineralization.

Full textAbstract:
This paper concerns the study of sex-biased dispersal patterns as related to genealogical and geographical distribution in the Native American, Comca'ac Community of Punta Chueca, Sonora, Mexico. The Comca'ac Community is an isolate community that exemplifies the conditions of being both spatially and temporally structured around a prescribed relational system, which are desirable conditions for research on kin-structured communities. Agricultural communities are typically patrilocal and follow the trend of female-biased dispersal while hunter-gatherer societies follow the trend of matrilocality about equally often and favor male-biased dispersal. Industrialized communities have yet to be accurately classified as demonstrating a definite male-biased dispersal pattern, female-biased dispersal pattern, or neither as it is a continuously evolving society of relative instability. As the Comca'ac have refused to incorporate agriculture into their economy and proven to be a traditional, nonindustrialized community, it was predicted that they would be patterned after a matrilocal community that exhibits male-biased dispersal. By collecting genealogical (degrees of genetic relatedness) and geographical (location of households) data of the Comca'ac, local kin densities were calculated of the mother and father of the offspring of the community to support the hypothesis of the Comca'ac Community as a matrilocal community with a strong pattern of female philopatry.

Full textAbstract:
This dissertation examines the opportunities and constraints surrounding the production and commercialization of bacanora, which is analyzed as an economic alternative for Sonora, in the context of a new legal and economic environment that forces farmers to become competitive and efficient. It integrates many topics related to the knowledge of Agave angustifolia and other Agavaceae and the study of several distillates from agaves, contributing to the emergence and development of the bacanora industry in Sonora, Mexico. The economy of small-scale bacanora producers in the sierras is analyzed. Cost and return estimates for the activity show the relative profitability of bacanora making. Subsequent analyses of marketing strategies indicate that serrana producers have potential in bacanora production by adopting or adapting different technologies and marketing schemes. The new institutional frame will increase competition among producers, which in turn will put greater pressures on agave populations. Therefore, more research on domestication of agave is required to find sustainable solutions to avoid overexplcitation of the resource. The major outlet for increased bacanora production is the international market, especially the United States. However, regional and national markets might provide an important group of consumers, as derived from the study of the tequila and mescal industries.

Full textAbstract:
Most of dengue transmission occurs in tropical and subtropical zones. As a result, studies on the dynamics of dengue transmission are principally focused in these areas. Less is known about the dynamics of dengue transmission and the interplay of social and climatic determinants in arid regions located at the fringe of transmission zones. This dissertation uses surveillance data from the state of Sonora, an arid region in northern Mexico, to examine three specific aims: 1) to assess relationships among social and climatic factors utilizing locality-level dengue incidence data across the state of Sonora, 2) to determine the correlation between the spatial pattern of dengue cases during an outbreak in Hermosillo, a large urban area, and neighborhood-level socio-economic and water supply factors using a novel case-control study design, and 3) to determine how dengue cases disseminated across two arid cities, Hermosillo and Navojoa, and to determine if changing socio-demographic patterns were similar between cities. Results from the first ecological study indicated that the distribution of dengue across the state was associated most strongly with the climatic gradient and, secondarily, by population size and lack of education. Underreporting in rural areas with lower access to transportation infrastructure was also detected. We demonstrated that a spatially-based case-control study design was useful in identifying associations between dengue transmission and neighborhood-level characteristics related to population density, lack of access to healthcare and water supply restrictions. Finally, the spatio-temporal study identified common patterns between the two cities/outbreaks. Dengue transmission arose and was maintained for 2-3 months in specific foci areas characterized by low access to healthcare and then the disease moved to contiguous areas. Recommendations for surveillance and control programs based on these results include: 1) in small localities at risk of transmission a combination of active and passive surveillance should be carried out for a period of time to determine if transmission is occurring, 2) monitoring water storage practices during water restrictions and ensuring appropriate messaging about covering storage containers should be made, and 3) spatial monitoring of dengue cases and agency reaction to initial disease occurrence could reduce spread to adjacent areas.

Full textAbstract:
This study investigates the relationship between the evolution of the igneous and hydrothermal systems in the Cananea mining district located in northern Sonora, Mexico. The Cananea district was chosen for this study because post-mineral uplift and erosion has tilted the Cananea Range ∼15° to the east and exposed an oblique section through approximately 6 vertical kilometers of a mineralized volcano-plutonic system and because porphyry-related stockwork, breccia, and pegmatitic silicate-sulfide mineralization are all well developed and well exposed. Major, trace element, and isotopic data suggest that the Laramide (∼64-56 Ma) igneous rocks represent a cogenetic calc-alkaline magmatic series ranging in composition from gabbro to granite. Neodymium isotope (εNd = +0.7 to -5.7) and strontium isotope (⁸⁷Sr/⁸⁶Sr(initial) = 0.70570 to 0.71037) values show a smooth inverse correlation and combined with the major and trace element data suggest that the Laramide rocks evolved from a mantle-derived parent melt by coupled assimilation and fractional crystallization. Phase petrology, mineral compositions, whole rock geochemistry, and alteration mineralogy indicate water, metal, chlorine, and sulfur content of the magmas increased with increasing differentiation and reached a maximum in late stage differentiates. The mineralized quartz-feldspar porphyries represent the rapid upward emplacement of this enriched differentiate. Porphyry-related mineralization in the Cananea district includes pegmatitic silicate-sulfide mineralization represented by the La Colorada and Maria deposits. Detailed field and geochemical work on the Maria deposit suggests that the fluids, alteration assemblages and paragenetic relations in silicate-sulfide pegmatites are similar to those seen in stockwork- and breccia pipe-hosted porphyry Cu systems, but that silicate-sulfide mineralization represents transitional conditions in which magmatic fluids are concentrated in a small volume and undergo efficient cooling and decompression leading to formation of high-grade telescoped mineralization.

Full textAbstract:
The Cabullona Basin of northeastern Sonora is a structural depocenter that was formed during Late Cretaceous time. The 2.5 km-thick sedimentary fill of this basin, the Cabullona Group, is composed in ascending order of the Corral de Enmedio formation, Camas Sandstone, Packard Shale, Lomas Coloradas formation, and, laterally equivalent to the last two units, El Cemento conglomerate. Abundant vertebrate and invertebrate as well as pollen identifications from these units indicate the Cabullona Group is of middle Santonian to Maastrichtian age. The Corral de Enmedio formation represents shallow lacustrine deposits. Lithofacies of the Camas and Lomas Coloradas formations indicate they were deposited by braided- and meandering-fluvial systems, whereas the eight members of the Packard Shale represent complex fluvio-deltaic-and-lacustrine systems. The El Cemento conglomerate is a thick clastic wedge of coarse-grained alluvial deposits that was deposited adjacent to the structural margin of the basin. Clast composition and paleocurrent directions of the El Cemento conglomerate indicate it was derived from strata of the nearby uplift of the Sierra Anibacachi-Cerro Cabullona. The low-angle, southwest directed Cabullona thrust fault that separates the uplift from the basin formed the structural margin of the basin. The tectono-sedimentary history of the Cabullona Group, its age and regional tectonic setting support the idea that this basin was formed because of typical Laramide-style deformation and indicates that the Rocky Mountain foreland province of Laramide deformation extended southward to northeastern Sonora.

Full textAbstract:
This dissertation addresses Plutarco Elías Calles's government in the Mexican state of Sonora between 1915 and 1919, the years immediately following the period of most intense armed conflict in the Mexican revolution. Calles, the most astute and influential politician to emerge from the revolutionary struggle as well as the founder of the modern Mexican state, has been the most conspicuously ignored figure in the extensive historiography on the revolution. Until very recently it was generally accepted that Calles's political development began with his appointment in 1920 as Obregón's interior minister, and that from this office and later as president he pioneered corporatistic programs of agrarian reform and labour organization. Furthermore, revisionist historians have long characterized Calles as the principal influence in the betrayal of the supposedly more 'radical' and 'revolutionary' movements led by Villa and Zapata, who represented popular aspirations and a nationalistic response towards foreign capital finally redeemed by President Cárdenas in the late 1930s. My research, which in a narrative sense complements the wellknown work of the Mexican historian Héctor Aguilar Camín, suggests that the half decade of the callista state government in Sonora had a direct and important bearing on the future character of Mexican government and politics. Indeed, I have found Calles's governorship in Sonora to be a dry run for policies later implemented nationally. Calles pursued a programme which included the expansion of the public education system, substantial, often militarized agrarian reform, advanced labour reforms and the promotion of unions linked to the government, and the successful submission of large American firms to Mexican law; he expelled the Catholic clergy from the state and enforced the prohibition of alcohol and gambling.

Full textAbstract:
The present study utilizes survey data (n = 415) collected in the Migrant Border Crossing Study from repatriated Mexican migrants to examine three important questions regarding unauthorized migration attempts through southern Arizona. First, what factors explicate migrants' modes of crossing? Second, do coyote fees vary among people who rely on smuggling services to cross the border? If so, what accounts for this variation? Third, what factors shape encounters with bajadores while traversing the desert? The present analyses expand on previous studies examining the unauthorized crossing in multiple ways. For instance, I empirically test the role of a "culture of migration" in explaining modes of crossing, coyote fees, and bajador encounters. I also differentiate between two main types of coyotes: "border business" and "interior." I then examine whether crossing with a coyote mediates the risk of encountering bajadores during the journey. Overall, there are important differences in crossing modes and coyote fees. Women are more likely to travel with both coyote types, while the opposite is true for more experienced migrants. Older migrants and people who cross during summer months are less likely to travel with an "interior" coyote. The strongest predictor of higher smuggling fees is the region of a person's U.S. destination. Higher coyote fees are also associated with immigrants' higher educational attainment, being married, being the sole economic provider for one's household, and higher household income. More experienced migrants, and those crossing in larger groups or during the summer also pay higher fees, however fees do not vary by gender, age, or social capital. These findings are somewhat consistent with the extant literature on human capital and risk tolerance/aversion, but run counter to the vast migration literature emphasizing the importance of social capital in the migration process. Finally, the risk of encountering bajadores is not higher for males, young adults, the less educated, and the more impoverished, which contradicts extant findings in the victimology literature. With the exception of crossing corridor and time spent in the desert, no other factors increase the risk of encountering bandits more than traveling with a coyote. Implications and possible future research are discussed.

Digital analysis of thematic mapper images and digital elevation model (DEM) of the Puerto Libertad area, emphasized a NE-E structural pattern and a less evident N-S structural trend. These structures may correspond to the distensive mechanisms of the opening of the Gulf of California. Also, semicircular structures in the area were recognized. These are associated to plutonic bodies or local volcanic centers. Exploration targets are most likely to occur in the last type of structures. Analysis included multispectral ratios of bands 5/7 and 5/1 to enhance lithologic discrimination and alteration zones especially hydroxyl-bearing and ferric iron alterations. Principal component analysis to enhance spectral data was also performed. Images revealed new lithologic subdivisions in units previously mapped. Analysis of DEM data and gradient operators from the first principal component image were analyzed to extract textural information.

Full textAbstract:
The presidial system was the focus for Spanish and Mexican military operations in northern New Spain. The Spanish established these garrisons to provide their settlers and missionaries protection from hostile indigenous tribes opposing expansion into their territories. Between 1692 and 1776, presidios were established on the Sonoran frontier at Fronteras, Terrenate, Horcasitas, Santa Cruz, Altar, Tubac, Bavispe, Bacoachi, and Tucson. The Spanish and Mexican governments never completely solved the problem of adequately supplying the Sonoran presidios with men and materials to achieve dominance over the native populations. These conditions left the presidios and civilian population exposed to attack and harrassment by hostile Indians. Examination of the major events concerning the presidios from 1790 to 1835, including the Apache pacification policies, establishment of "Indian" presidios, the Mexican war for independence, transfer from Spanish to Mexican control, and the study of presidial personnel, reveals how the presidio functioned as a major frontier institution.

Following decades of protectionism, in 1982 Mexico reacted to its foreign debt crisis by implementing extreme structural adjustment policies and it has continued a pattern of neoliberalism, increasingly opening its economy to international markets. The cumulative impacts of these policies have negatively affected the majority of the Mexican population, and researchers have documented the detrimental effects of neoliberal polices on working and middle classes in other contexts. Based on ethnographic research in Nogales, Sonora, this paper will describe a particular group of Mexicans who have nevertheless risen to middle class status throughout this time period. It will situate them within an industrializing border economy and will investigate some of the factors, both internal and external, that have contributed to their success in this endeavor. Finally, it will raise questions for future research, such as: Is this middle-class sustainable?

The purpose of this study was to analyze strategies for sustainable development, and especially the opportunities and constraints for sustainable development in arid lands. This study examines how environmental, economic, political, and social factors influence regional development. Because of the complexity of the problem, a two-perspective interdisciplinary approach was used. First, from a historical perspective, a farming systems approach focuses on understanding the interaction of population, environmental, technological and institutional factors. Second, and from an economic perspective, a linear progranuning model examines the interaction of the North American Free Trade Agreement (NAFTA) as well as the Amendment to Article 27 of the Mexican Constitution in regional-level current and expected transformations. Research was conducted in central Sonora, located in northwest Mexico, one of the arid zones of the Sonoran desert. From colonial times to the early 20th century chaotic changes occurred in Sonora. These changes were influenced by cultural, environmental, and technological factors. Cultural differences between the indigenous Sens and Spaniards prompted a long period of conflict. Seris were a hunter-gatherer nomadic group, the Spanish conquerors searched for gold and minerals, and the later Mestizos were farmers and ranchers. The strategy of hunting-gathering not only permitted the Seris to cope with a hostile, arid climate, but also helped them resist Spanish efforts to colonize or exterminate them. In contrast, environmental barriers limited the introduction of agricultural systems into the Seri territory and limited the rapid conquest of the Sens as well. Nonetheless, the Seris were nearly exterminated as a result of this conflict, and their territory reduced to the coastal margins of the Gulf of California.

Full textAbstract:
Phytostabilization is a remediation technology that uses plants for in-situ stabilization of contamination in soils and mine tailings. The objective of this study was to identify native plant species with potential for phytostabilization of the abandoned mine tailings in Nacozari, Sonora in northern Mexico. A flora of 42 species in 16 families of angiosperms was recorded on the tailings site and the abundance of the most common perennial species was estimated. Four of the five abundant perennial species showed evidence of regeneration: the ability to reproduce and establish new seedlings. A comparison of selected physicochemical properties of the tailings in vegetated patches with adjacent barren areas suggests that pH, electrical conductivity, texture, and concentration of potentially toxic elements do not limit plant distribution. For the most abundant species, the accumulation factor for most metals was <1, with the exception of Zn in two species. A short-term experiment on adaptation revealed limited evidence for the formation of local ecotypes in
Prosopis velutina
and
Amaranthus watsonii
. Overall, the results of this study indicate that five native plant species might have potential for phytostabilization of the Nacozari tailings and that seed could be collected locally to revegetate the site. More broadly, this study provides a methodology that can be used to identify native plants and evaluate their phytostabilization potential for similar mine tailings.

Full textAbstract:
Pervasive social and ecological water crises in Mexico remain, despite over two decades of legal and institutional backing for Integrated Water Resources Management (IWRM) as a policy tenet. In this article we apply a socialshed analysis to uncover and understand the geographical and jurisdictional forces influencing the social construction and simultaneous fragmentation of the San Miguel Watershed (SMW) in the state of Sonora, in Mexico's water-scarcity bulls-eye. Specific insights derived from an empirical analysis include that water management (WM) is socially embedded in dense networks of family and friends, farmers and ranchers, citizens and local government - all to varying degrees sharing information about local water crises. Irrigation water user representatives (WUR) are connected across communities and within their own municipalities, but interwatershed social links with other WUR are virtually nonexistent, despite high levels of awareness of crossmunicipality WM problems. Implementation of IWRM as a federal policy by a single agency and the creation of basin councils and subsidiary technical committees for groundwater management have not been sufficient for technical - much less social - integration at the watershed level. This study shows that the SMW socialshed remains fragmented by local jurisdictions; without coordinated agency-jurisdiction-local action fomenting social connections, a socialshed will not emerge.

Full textAbstract:
Although reptiles are well known for their low energy requirements and high efficiencies of biomass conversion, few studies have addressed the ecology and energetics of species with very low activity levels. I investigated the ecology and energetics of two such reptilian groups: helodermatid lizards, and viperid snakes. I radiotracked Mexican beaded lizards and three rattlesnake species in their natural environments to determine their activity patterns, the time and energy they invest in activity, home ranges, thermal biology, habitat and other resource use, and behavior. I measured metabolic rates in the laboratory to determine rates of energy use. Beaded lizards had a mean home range of 21.6 ha, an activity peak at 1800 hrs and traveled, on average, 25.3 km during approximately 121 h of surface activity over the year. They had very low metabolic rates during rest. However, helodermatids had maximal rates of oxygen consumption that were among the highest of any lizard measured, a trait that may be adaptive during their intensive male-male agonistic behaviors. Males had significantly higher capacities for aerobic activity than did females. Heloderma horridum can fulfill its annual maintenance energy requirements with a quantity of prey equivalent to approximately 1.4 times its body mass. Rattlesnakes had a mean home range size of 4.6 hectares and traveled, on average, 12.4 km over approximately 95 hours of annual surface activity. Rattlesnakes spent considerable time inactive on the surface, whereas Heloderma spent the vast majority of their time resting in shelters. Heloderma and Crotalus had similar body temperature preferences for activity (around 30 C). Like Heloderma, Crotalus had very low rates of metabolism during rest. A 300-g rattlesnake had a standard metabolic rate only 40% that of other squamate reptiles of similar mass, and could fulfill its yearly maintenance energy requirements with a prey quantity equivalent to 0.93 x its body mass, which could be met with 2-3 large meals. After feeding, free-ranging rattlesnakes exhibited thermophilic responses that varied, in part, due to their reclusive behavior, and thermal constraints in the environment. The temperatures selected for digesting and activity are apparently similar in rattlesnakes.

Full textAbstract:
Riparian systems are important for breeding bird communities and are highly used as migratory corridors; however, their importance for wintering birds has not been assessed systematically. In order to assess the value of riparian areas for birds wintering in Sonora, data from 1,816 standard point counts were collected from 87 locations during January and February 2004-2006. A total of 253 species were detected across 14 vegetation types, including nine categories of riparian vegetation. The mean number of species and individuals detected per count was significantly higher in riparian vegetation than in non-riparian vegetation for migratory species, but not for residents. Riparian bird communities are different from those in non-riparian habitats, and contribute 22% of the regional avifauna's species.Anthropogenic disturbance has imposed significant changes in riparian habitats, and is known to have negative effects on biological communities. To assess the effects of human induced disturbance on wintering bird communities, I recorded community composition, relative abundance of species, and three indicators of bird condition in relatively undisturbed and highly disturbed sites at three river systems in Sonora. There is, in general, little effect of disturbance on the composition of wintering communities, with less than 20% of the most common species having significant differences in their abundances between relatively undisturbed and highly disturbed sites. Condition indicators were similar in the two disturbance levels, but the mean heterophil/lymphocyte ratio in the blood of sampled birds showed increased levels of physiological stress in disturbed sites. A more experimental approach is needed to determine the specific cause of the stress expression in leucocytes.
Modification of natural flooding regimes has modified riparian areas, as has been the case in the Colorado River Delta. I present a summary of the changes experienced by riparian systems and some of the measures implemented for riparian restoration in the southwestern United States, and then I compare the scenario with that in central Sonora, where some of the same stressors exist on riparian systems, but where traditional management practices have also mitigated some of the negative consequences of flow control along mid-sized river systems.

Full textAbstract:
The present study has encompassed a series of field observations and theoretical considerations related to physical, chemical, and biological factors defining the process of eutrophication in the Guaymas system. Additionally, the work has produced the basic ecosystem model of the system through the modelling of the hydrodynamics, sediment dynamics, budget dynamics, net ecosystem metabolism and the potential for eutrophication. These findings produce an overall assessment of the system, which together with the environmental legislation and socio-economic concerns, allows those factors influencing decision making to be highlighted. In general, the knowledge of the hydrodynamic features indicates that the flushing capacity of the system may be insufficient to remove pollution discharged into the Guaymas sub-system and Estero el Rancho. There is a residual mass of water that exchanges from the Empalme sub-system to the Guaymas sub-system. Simulation of the trends for potential net transport of sediment indicates that bedload transport is likely to occur toward the head of the Guaymas sub-system. For the Empalme subsystem, there was a net bedload displacement toward the mouth. Mathematical interrelationships between measured phytoplankton biomass and environmental parameters shows through a MRA model that nearly 100% of its variance is influenced by nutrients, pH, temperature and salinity. The stoichiometric Redfield approach indicates that nitrogen is a limiting factor of the phytoplankton biomass growth in the Guaymas system, when other factors such as light, sinking, grazing, temperature and salinity gradients are not. However, an analysis of the two major subsystems shows that nutrients limiting in the Guaymas sub-system are closely related to phosphorus loads from wastewater sources, whereas for the Empalme sub-system, nutrient limitation was alternately by nitrogen and phosphorus. A primary quantitative outcome of the eutrophic status is given, using a simple biochemical budgetary approach, indicating that the Guaymas system is a net heterotrophic system, with a value of -4811.72 mmol.C.m^.y'1. Using a simple box model to characterise the potential hyper-trophic conditions suggests that phosphorus reduction in the system is accompanied by an improvement in water quality, hence management strategies must encourage P control from wastewater discharges into the sub-system. An analysis of the particular case of the Guaymas system in the context of the Mexican Environmental Legislation indicates that the quality standards set for the system will depend very much upon the designation ultimately used for the system. For instance, if some areas of the Guaymas sub-basin are designated for industrial use, a polluted influence is likely to occur in an area near the development. However, the areas influenced by this development must not pose a threat for the people living the Guaymas basin as stated in the Mexican Environmental Legislation.

Traditionally, the Onavas Valley located in the middle Rio Yaqui, has been identified as part of the Rio Sonora archaeological tradition. However, no archaeological research has taken place in this region to verify this cultural model. This work presents new data from the Onavas Valley Archaeological Project (OVAP), conducted in the summer of 2003 and 2004, which provide basic data to solidify our understanding of an archaeologically poorly researched area, examine its role in interactions with the neighboring archaeological areas, and contrast the Rio Sonora tradition model. The methodology used combine archaeological survey, artifact analysis, and ethnohistorical research. A full-coverage systematic pedestrian survey, at the center of the Onavas Valley, was conducted covering an area of 67 km² and recorded 122 new sites. Three research approaches where set to discern and define the archaeological tradition within the Onavas Valley and then examine extra-regional interactions with neighboring archaeological areas. Those are 1) building a local chronology and a diagnostic inventory of material culture; 2) establishing the landscape structure (settlement pattern and ritual landscape) of the area; and 3) collecting and analyzing evidence for the manufacture, use, and exchange of trade goods. At the end of the material analysis, the OVAP conclude that the Onavas Valley had more cultural relation with the Huatabampo archaeological tradition than to the Rio Sonora archaeological tradition. Finally a comparison of the cultural landscape of the Onavas Valley with those of the Marana, Cerro de Trincheras, and Paquime traditions was made, to see different cultural developments in similar geographical condition using same methodological and analytical framework.

The Tohono O'odham Nation of southern Arizona and northern Sonora Mexico has two distinct and distinctive cultural, social, political and federal histories. The American government politically acknowledges one group while the other is entrenched in Mexican social policy that regards Indigenous peoples as equals to the Mestizo population known as campesinos or peasants. The Sonoran Tohono O'odham community of Al Pi'ichkin or Pitiquito, Sonora, Mexico, has managed to persist and survive into the twenty first century despite the presence of an international boundary and the assimilative efforts of Mexican socio-federal Indian policy.This is an exploration of the issue of cultural continuity within the community of Pitiquito, Sonora Mexico via the following eight themes which emerged from my field work: the oral tradition; kinship; tradition and modernity in 2007; the Feast of St. Francis at Magdalena de Kino; nationalism; importance of photography; identity; and cultural persistence.

Full textAbstract:
Ecological change very often parallels social change. The concept of the social-ecological system (SES) provides a holistic means of accounting for the dualistic nature of human-environmental interactions by acknowledging that social, political and economic factors influence and are in turn influenced by the processes of ecological change. These transformations can be contextualized within nested adaptive cycles of change that respond to pre-existing conditions and which provide new opportunities for system actors. The adaptive cycle also grants that processes of social and ecological change may be permanent, irreversible and result in new configurations not previously imaginable. The ability for an SES to respond to these processes of change depends upon its resilience which defines the range of reversible change within a stable state. Resilience is determined by a system's vulnerability, by the pre-existing or available capital.Within this dissertation, I assert that resilience is an important factor to consider in studying arid land political ecology. Resilience can be influenced by both institutional and environmental factors. I assert here that institutional factors alone cannot explain the pace of change in a particular political ecology. While institutions constitute the dominant signals with regards to economic decision making, environmental signals may be ultimately more significant. I utilize a detailed case study focused upon a watershed and ejido in northwestern Mexico. This case study demonstrates the influence of strong political and economic signals that influence local economics. Nature bats last and can exert powerful forces over institutional choices. Using this case study, I demonstrate how a dramatic shift in climatic as well as hydrologic regimes leads ultimately to a general degradation of agropastoral ecological resources and their replacement with new, stable but less desirable states. Land-use has subsequently changed. The latter set of ecological changes has become a sort of death of a thousand cuts that has reduced the community's ability to tap local natural capital and thereby generate economic capital. This study is intends to contribute to our knowledge of political ecology by evaluating the concepts of ecological resilience, multiple stable states, and adaptive cycles to the study of these social-ecological systems.
