Classic Textiles From Cueva Del Lazo (Chiapas, Mexico): Archaeological Context And Conservation Issues, Davide Domenici, Gloria Martha Sánchez Valenzuela

PreColumbian Textile Conference VII / Jornadas de Textiles PreColombinos VII (2016)

The excavation of Cueva del Lazo, a cave on the cliffs of the Río La Venta River canyon in the Zoque region of Western Chiapas (Mexico), led to the discovery of a complex Late Classic post-sacrificial context where eleven children were buried wrapped in textile bundles. The environmental conditions of the dry cave allowed an extraordinary preservation of perishable materials including textiles, cordages, botanical remains, etc. In the first part of the paper we provide a brief introduction to the archaeology of the Selva El Ocote, as well as a description and interpretation of the Cueva del Lazo archaeological context. …

La Conservación De Dos Fardos Funerarios Provenientes De Contextos Arqueológicos: El Caso De La Cueva Del Lazo, Ocozocoautla, Chiapas Y La Cueva De La Candelaria, Torreón, Coahuila, México, Gloria Martha Sánchez Valenzuela

PreColumbian Textile Conference VII / Jornadas de Textiles PreColombinos VII (2016)

El presente artículo se enfoca en la conservación de dos fardos funerarios localizados en diferentes cuevas dentro de la República Mexicana que, a pesar de encontrarse en polos opuestos, se conservaron gracias a las condiciones de humedad y temperatura estables dentro de un contexto seco. Lamentablemente, en ambos casos, no existe un registro minucioso del contexto (mediciones de humedad, temperatura, análisis de sedimentos, entre otros), así como de las condiciones en las que estos se encontraban (elementos asociados –restos óseos, ornamentos, posición, etc) que permitan realizar una intervención lo más fehaciente posible. Estos ingresan a la CNCPC1 completamente colapsados, después …

Distribution And Conservation Status Of The Freshwater Gastropods Of Nebraska, Bruce J. Stephen

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

This survey of freshwater gastropods within Nebraska includes 159 sample sites and encompasses the four primary level III ecoregions of the State. I identified sixteen species in five families. Six of the seven species with the highest incidence, Physa gyrina, Planorbella trivolvis, Stagnicola elodes, Gyraulus parvus, Stagnicola caperata, and Galba humilis were collected in each of Nebraska’s four major level III ecoregions. The exception, Physa acuta, was not collected in the Western High Plains ecoregion. Seven indigenous species, Valvata tricarinata, Helisoma anceps, Campeloma decisum, Galba bulimoides, Physa jennessi, Ferrissia rivularis, and …

Incorporating Sociocultural Phenomena Into Ecosystem-Service Valuation: The Importance Of Critical Pluralism, Carena J. Van Riper, Amanda J. Landon, Sarah Kidd, Patrick Bitterman, Lee A. Fitzgerald, Elise F. Granek, Sonia Ibarra, David M. Iwaniec, Christopher M. Raymond, David Toledo

Department of Geography: Faculty Publications

Ecosystem-services scholarship has largely focused on monetary valuation and the material contributions of ecosystems to human well-being. Increasingly, research is calling for a deeper understanding of how less tangible, nonmaterial values shape management and stakeholder decisions. We propose a framework that characterizes a suite of sociocultural phenomena rooted in key social science disciplines that are currently underrepresented in the ecosystem-services literature. The results from three example studies are presented to demonstrate how the tenets of this conceptual model can be applied in practice. We consider the findings from these studies in light of three priorities for future research: (1) complexities …

Unusual Aerobic Performance At High Temperatures In Juvenile Chinook Salmon, Oncorhynchus Tshawytscha, Jamilynn B. Poletto, Dennis E. Cocherell, Sarah E. Baird, Trinh X. Nguyen, Valentina Cabrera-Stagno, Anthony P. Farrell, Nann A. Fangue

School of Natural Resources: Faculty Publications

Understanding how the current warming trends affect fish populations is crucial for effective conservation and management. To help define suitable thermal habitat for juvenile Chinook salmon, the thermal performance of juvenile Chinook salmon acclimated to either 15 or 19°C was tested across a range of environmentally relevant acute temperature changes (from 12 to 26°C). Swim tunnel respirometers were used to measure routine oxygen uptake as a measure of routine metabolic rate (RMR) and oxygen uptake when swimming maximally as a measure of maximal metabolic rate (MMR) at each test temperature. We estimated absolute aerobic scope (AAS = MMR − RMR), …

Protected Areas As Social-Ecological Systems: Perspectives From Resilience And Social-Ecological Systems Theory, Graeme S. Cumming, Craig R. Allen

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Conservation biology and applied ecology increasingly recognize that natural resource management is both an outcome and a driver of social, economic, and ecological dynamics. Protected areas offer a fundamental approach to conserving ecosystems, but they are also social-ecological systems whose ecological management and sustainability are heavily influenced by people. This editorial, and the papers in the invited feature that it introduces, discuss three emerging themes in social-ecological systems approaches to understanding protected areas: (1) the resilience and sustainability of protected areas, including analyses of their internal dynamics, their effectiveness, and the resilience of the landscapes within which they occur; (2) …

A Descriptive Analysis Of Regal Fritillary (Speyeria Idalia) Habitat Utilizing Biological Monitoring Data Along The Big Bend Of The Platte River, Ne, Andrew J. Caven, Kelsey C. King, Joshua D. Wiese, Emma M. Brinley Buckley

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Speyeria idalia populations have declined as much as 95 percent over the last three decades. Here we critically evaluate prairie habitat components along the Platte River in central Nebraska that S. idalia populations require in an effort to better inform conservation efforts. We utilized S. idalia count data from biological monitoring transects where vegetation, soils, land management, and flooding frequency data were also collected to describe the habitat constituents associated with S. idalia presence. We utilize comparative statistics, Pearson’s correlation analysis, and random forest analysis to model S. idalia habitat on land owned and managed by a small conservation NGO. …

Using Species Distribution Models To Define Nesting Habitat Of The Eastern Metapopulation Of Double-Crested Cormorants, Kate L. Sheehan, Samuel T. Esswein, Brian S. Dorr, Greg K. Yarrow, Ron J. Johnson

USDA Wildlife Services: Staff Publications

When organisms with similar phenotypes have conflicting management and conservation initiatives, approaches are needed to differentiate among subpopulations or discrete groups. For example, the eastern metapopulation of the double-crested cormorant (Phalacrocorax auritus) has a migratory phenotype that is culled because they are viewed as a threat to commercial and natural resources, whereas resident birds are targeted for conservation. Understanding the distinct breeding habitats of resident versus migratory cormorants would aid in identification and management decisions. Here, we use species distribution models (SDM: Maxent) of cormorant nesting habitat to examine the eastern P. auritus metapopulation and the predicted breeding …

A Matter Of The Soul: Our Human Relationship To Trees In Nebraska, Ariana Brocious

Department of English: Dissertations, Theses, and Student Research

We love trees. We connect with them more closely, relate to them more intimately, than almost any other plant. Nebraska, in the country’s heartland, may be known today for its fields of corn, soybeans, and cattle. But for the last 200 years, Nebraskans have also labored to fill their prairie state with trees. This obsession has touched all kinds of things: tax incentives, state slogans, farming practices, rural homeownership, urban water bills, state celebrations, land use and conservation.

A Matter of the Soul: Our Human Relationship to Trees in Nebraska is a work of narrative nonfiction that looks at how …
