Estimation Of Available Epinephrine Dose In Expired And Discolored Autoinjectors Via Quantitative Smartphone Imaging, Amirus Saleheen, Bill M. Campbell, Rebecca A. Prosser, Christopher A. Baker

United States National Park Service: Publications

Epinephrine autoinjectors (EAIs) are important first aid medications for treating anaphylaxis. A 10-fold price increase over the past 12 years and evidence that expired EAIs may still contain significant doses of available epinephrine have motivated interest in the efficacy of expired EAIs as treatments of last resort. Degradation of expired EAIs, which can be caused by improper storage conditions, results in various degrees of discoloration of the epinephrine solution. Previous studies have determined that significant epinephrine remains available in expired EAIs, but these have only considered EAIs that show no discoloration. Here, we investigate the potential for colorimetric estimation of …

Effects Of Culling White-Tailed Deer On Tree Regeneration And Microstegium Vimineum, An Invasive Grass, John Paul Schmit, Elizabeth R. Matthews, Andrejs Brolis

United States National Park Service: Publications

Reduction of forest regeneration due to overbrowsing by white-tailed deer is a growing concern for land managers. Abundant deer can impede forest regeneration through direct predation on tree seedlings. Additionally high deer density can facilitate the establishment of a dense understory of browse tolerant plant species that shades seedlings and persists even in the absence of deer. In response to these challenges, land managers have sought to reduce deer herds to restore tree regeneration, but few studies have evaluated the effectiveness of this management. Our study took place in Catoctin Mountain Park, a US National Park Service unit with a …

Nurse Rock Microclimates Significantly Buffer Exposure To Freezing T Temperature And Moderate Summer Temperature, Joshua L. Conver, Elliott Yarwood, Lucas D. Hetherington, Don E. Swann

United States National Park Service: Publications

Nurse tree canopies mitigate exposure to freezing temperatures that could result in injury or mortality to the saguaro cactus (Carnegiea gigantea). Abiotic objects have been hypothesized to provide similar beneficial microclimates. We used data loggers at 11 nurse rock sites to record daily daytime summer maximum and winter nighttime minimum temperatures at Saguaro National Park, Arizona, to examine the effectiveness of rocks to moderate seasonal temperature extremes in the microclimate. Temperatures at rock sites averaged 2 °C warmer than exposed open control sites in winter. We found that the efficiency of rocks to act as insulators significantly increased as temperature …

Beryllium-7 Elucidate Sediment Dynamics Of The Branford River Estuary, Connecticut, Usa, Gaboury Benoit, Matthew Hirschbeck, Beth Bisson

United States National Park Service: Publications

Berrylium-7 elucidates sediment dynamics (i.e., sources, sinks, deposition, and resuspension) in a Connecticut estuary. Average 7 −2−1 annual atmospheric deposition of Be is 290 mBq cm year. Sediment samples from 43 locations within the estuary show that 7Be deposition is spatially complex, but were statistically indistinguishable a year apart. Weekly time series of sediments indicate 7 that levels are nearly constant on this shorter time scale on ceradio active decay is taken into account. Be levels in sediments area balance between steady losses through radioactive decay and periodic pulse inputs following rainstorms. The water column was measured intensively during three …

Implications Of Organic Mass To Carbon Ratios Increasing Over Time In The Rural United States, W.C. Malm, B.A. Schichtel, J.L. Hand, A.J. Prenni

United States National Park Service: Publications

The thermal evolution procedure used by most monitoring programs in the United States to determine carbonaceous aerosol concentrations is referred to as the thermal‐optical reflectance method, where an aerosol sample that has been collected on a quartz filter is heated and evolved carbon is characterized as either organic (OC) or light absorbing carbon (LAC). Evolved carbon assigned to OC is multiplied by a factor, Roc, to achieve an estimate of organic mass. Over the last 10–15 years, Roc, estimated through multiple linear regression analysis of data collected in the Interagency Monitoring of Protected Visual Environments (IMPROVE) program, has increased at …

Berry Important? Wolf Provisions Pups With Berries In Northern Minnesota, Austin T. Homkes, Thomas D. Gable, Steve K. Windles, Joseph K. Bump

United States National Park Service: Publications

Wolves (Canis lupus) primarily provision pups by catching mammalian prey and bringing remains of the carcass to the pups at a den or rendezvous site via their mouths or stomach. In August 2017, we observed an adult wolf regurgitating wild blueberries (Vaccinium spp.) to pups at a rendezvous site in the Greater Voyageurs Ecosystem, Minnesota, USA, which is the only known observation of wolves provisioning pups with wild berries. This observation, in combination with other evidence from the Greater Voyageurs Ecosystem, suggests wild berries might be a more valuable food source for wolves in southern boreal ecosystems than previously appreciated.

Modelling Pinniped Abundance And Distribution By Combining Counts At T Terrestrial Sites And In-Water Sightings, Steven L. Whitlock, Jamie N. Womble, James T. Peterson

United States National Park Service: Publications

Pinnipeds are commonly monitored using aerial photographic surveys at land- or ice-based sites, where animals come ashore for resting, pupping, molting, and to avoid predators. Although these counts form the basis for monitoring population change over time, they do not provide information regarding where animals occur in the water, which is often of management and conservation interest. In this study, we developed a hierarchical model that links counts of pinnipeds at terrestrial sites to sightings-at-sea and estimates abundance, spatial distribution, and the proportion of time spent on land (attendance probability). The structure of the model also allows for the inclusion …

Dental Microwear As A Behavioral Proxy For Distinguishing Between Canids At The Upper Paleolithic (Gravettian) Site Of Predmostí, Czech Republic, Kari A. Prassack, Josephine Dubois, Martina Laznickova-Galetova, Mietje Germonpre, Peter S. Ungar

United States National Park Service: Publications

Morphological and genetic evidence put dog domestication during the Paleolithic, sometime between 40,000 and 15,000 years ago, with identification of the earliest dogs debated. We predict that these earliest dogs (referred to herein as protodogs), while potentially difficult to distinguish morphologically from wolves, experienced behavioral shifts, including changes in diet. Specifically, protodogs may have consumed more bone and other less desirable scraps within human settlement areas. Here we apply Dental Microwear Texture Analysis (DMTA) to canids from the Gravettian site of P�redmostí (approx. 28,500 BP), which were previously assigned to the Paleolithic dog or Pleistocene wolf morphotypes. We test whether …

Bird Community Monitoring At Tallgrass Prairie National Preserve, Kansas, Status Report 2001–2018, David G. Peitz, Kathleen A. Kull

United States National Park Service: Publications

Executive Summary

In 2001, the Heartland I&M Network initiated breeding bird surveys on Tallgrass Prairie National Preserve, Kansas, to assess the ecological integrity of the preserve’s habitat. Birds are an important component of ecosystems and can serve as good indicators of habitat change in an ecosystem. In the 17 years of bird surveys at the preserve (2001 to 2018, excluding 2003), there were 2,089 plot visits and 119 different bird species recorded, 96 of which have the potential to breed within the preserve. These 96 species represent approximately 81% of the total species one would reasonably expect to have breeding …

Measuring Spatial And Temporal Shifts In Forest Structure And Composition In T High Elevation Beech Forests In Response To Beech Bark Disease In Great Smoky Mountains National Park, Lee Rubmle, Glenn Taylor, Joshua B. Grinath, Ashley B. Morris

United States National Park Service: Publications

Exotic forest pests and pathogens are among the most serious environmental threats to millions of hectares of forested land worldwide. Beech Bark Disease (BBD) is a non-native, pathogenic complex consisting of associations between scale insects and fungi. First confirmed in Great Smoky Mountains National Park (GRSM) in 1986, this complex has since threatened local high elevation beech forests, which are G-1 ranked (critically imperiled) forest communities where American beech (Fagus grandifolia Ehrh.) is a foundational tree species. In 1994, GRSM initiated the BBD Monitoring Protocol at 10 high elevation beech forest plots in the Park. The plots were sampled biennially …

Prey Of Reintroduced Fishers And Their Habitat Relationships In The Cascades T Range, Washington, Mitchell A. Parsons, Jeffrey C. Lewis, Jonathan N. Pauli, Tara Chestnut, Jason I. Ransom, David O. Werntz, Laura R. Prugh

United States National Park Service: Publications

Conservation and recovery of forest carnivores requires an understanding of their habitat requirements, as well as requirements of their prey. In much of the western United States, trapping and habitat loss led to extirpations of fishers (Pekania pennanti) by the mid-20th century, and reintroductions are ongoing to restore fishers to portions of their former range. Fisher recovery in Washington State has been limited by isolation from other populations, but other potentially important factors, such as diet of fishers in this region and prey availability, have not been thoroughly investigated. We collected hair samples from potential prey and fishers for stable …

Plains Zebra (Equus Quagga) Behaviour In A Restored Population Reveals Seasonal Resource Limitations, Charli De Vos, Alison J. Leslie, Jason I. Ransom

United States National Park Service: Publications

A once abundant species, plains zebra (Equus quagga), is declining across much of sub-Saharan Africa. Reintroduction efforts at Majete Wildlife Reserve, Malawi, have resulted in rapid population increases, but little is known about how such populations resemble natural populations socially or behaviourally, and what those attributes may reveal about restoration success. Incorporating behavioural knowledge into conservation efforts is an important tool for managing the effects of habitat fragmentation and resource competition. The aim of this study was to quantify the daylight time budget of both family and bachelor bands of reintroduced plains zebra to determine if such behaviours …

Predicting Livestock Depredation Risk By African Lions (Panthera Leo) In A Multi-Use Area Of Northern Tanzania, K. Beattie, E. R. Olson, B. Kissui, A. Kirschbaum, C. Kiffner

United States National Park Service: Publications

Human-wildlife conflicts, especially those involving large carnivores, are of global conservation and livelihood concern and require effective and locally-adapted prevention measures. Risk of lion attack on livestock (i.e. depredation) may vary seasonally and may be associated with variation in wild prey abundance or landscape characteristics. To test these competing hypotheses, we used a resource selection approach, and determined whether prey catchability (indicated by geo-spatial variables), or prey availability (indicated by modeled abundance recorded via camera traps) explained spatial and seasonal variation in livestock depredation risk by African lions on Manyara Ranch Conservancy, a multi-use area in northern Tanzania. Seasonal variation …

Direct And Indirect Effects Of Temperature And Prey Abundance On Bald Eagle Reproductive Dynamics, Joshua H. Schmidt, Judy Putera, Tammy L. Wilson

United States National Park Service: Publications

Understanding the mechanisms by which populations are regulated is critical for predicting the effects of large-scale perturbations. While discrete mortality events provide clear evidence of direct impacts, indirect pathways are more difficult to assess but may play important roles in population and ecosystem dynamics. Here, we use multi-state occupancy models to analyze a long-term dataset on nesting bald eagles in south-central Alaska with the goal of identifying both direct and indirect mechanisms influencing reproductive output in this apex predator. We found that the probabilities of both nest occupancy and success were higher in the portion of the study area where …

Food Deserts In Urban Areas, Regina Bellian

The Downtown Review: An Interdisciplinary Journal Written and Peer-Reviewed by Mandel Honors College Students at Cleveland State University

This paper illustrates the issue of food deserts faced by urban areas in three parts. Part one focuses on defining food deserts and what exactly the term denotes as well as who is affected by their present existence socially, physically, and economically. Part two presents research on some of the current policies and programs in place to address the issue of food deserts and discusses a few of the difficulties in implementing them. These approaches are then further analyzed for effectiveness in varying regions. Part three explores a handful of alternative methods to combat this urban issue in order to …

El artículo presenta información etnográfica y una interpretación etnológica sobre los Tagaeiri y Taromenane como parte de los grupos familiares en aislamiento que habitan en el Yasuní, su forma de vida tradicional y su territorio, en un contexto de actores externos que inciden en la generación de violencia y de amenaza a su supervivencia. Sobre los pueblos en aislamiento en Ecuador existe información referenciada en datos indirectos que han dado indicios de presencia a partir de registros de rastros e imágenes satelitales y algunos datos directos, como avistamientos, encuentros en la selva, fotografías aéreas y, el principal, encuentros que generaron …

Good Reasons Or Bad Conscience? Or Why Some Indian Peoples Of Amazonia Are Ambivalent About Eating Meat, Stephen P. Hugh-Jones

Tipití: Journal of the Society for the Anthropology of Lowland South America

Originally written for a conference on meat attended by farmers, anthropologists, people involved in cultural affairs, and other members of the public, and seeking to avoid emphasis on cultural difference, this paper explores common ground between Euro-American and Amerindian ambivalence about meat consumption. Meat-eating raises two shared concerns: an intuitive recognition of the resemblances between humans and animals and an uncomfortable awareness that human life often depends on the death and destruction of other living beings. I suggest that, behind some obvious cultural differences, Amazonian shamanic and ritual procedures aimed at the de-subjectification of meat share points in common with …

La Política Pública De No Contacto De Los Pueblos Indígenas En Aislamiento Y Contacto Inicial, Carlos Antonio Martin Soria Dall'orso

Tipití: Journal of the Society for the Anthropology of Lowland South America

Esta articulo revisa la evolución de la legislación amazónica para la protección de los Pueblos Indígenas en Aislamiento y Contacto Inicial (en adelante PIACI) a través de una mirada al derecho comparado amazónico. Luego se propone cual es la situación territorial de los PIACI en varios países amazónicos, para entender que estos pueblos habitan paisajes complejos de derechos otorgados a ellos pero, a veces también al Estado y a terceros. A continuación se reflexiona sobre la propuesta de reconocer Corredores de Protección PIACI como una propuesta que permite integrar varias áreas de protección PIACI que son colindantes para así a …

The "Uncontacted" As Third Infamy, George Mentore

Tipití: Journal of the Society for the Anthropology of Lowland South America

This paper principally addresses the "problem" of anthropological thinking, that is, on how and why it remains with us and not with the peoples who do not subscribe to our contested regimes of truth. From my research on the topic, it appears we have not achieved any substantial moral progress on the question of exposure to indigenous otherness since the first European "contact." This failure is primarily due to our hardheaded rationalist refusal to accept our inability to access the felt reality of the Other directly. Or, better still, of the failure of our language to obtain the shared reality …

Miradas Del Aislamiento Y Del Contacto: Una Crónica Sobre Los Llamados Mashco Piro, Luis Felipe Torres Espinoza

Tipití: Journal of the Society for the Anthropology of Lowland South America

Este artículo presenta una breve crónica sobre la historia y el presente del pueblo indígena denominado mashco piro, considerado en situación de “aislamiento” por los gobiernos de Perú y Brasil. Además de considerar las amenazas externas que existen sobre sus territorios y sus modos de vida, se propone tomar en cuenta la agencia de los mashco piro al lidiar con este contexto. En este sentido, se plantea recurrir al conocimiento etnológico producido sobre aspectos clave de las sociedades indígenas de la Amazonia (como la guerra, el intercambio y el parentesco), para un entendimiento más completo de su forma de …

A Brief Comment On Hugh-Jones's "The Origin Of Night And The Dance Of Time", Geraldo Andrello

Tipití: Journal of the Society for the Anthropology of Lowland South America

In this comment on Hugh-Jones’s article "The Origin of Night," Geraldo Andrello argues that the politics of myth narrations and ritual performances are enacted through the regulation of temporality and explains why it is that all-important status distinctions are brought into existence through the retelling of permutations of the Origin of Night myth.

Christianity + Schooling On Nature Versus Culture In Amazonia, Aparecida M. N. Vilaça

Tipití: Journal of the Society for the Anthropology of Lowland South America

Based on the analysis of Evangelical Biblical translations, as well as on the school writing of Wari' (Southwestern Amazonia) students, produced in indigenous secondary school classrooms and at the intercultural university, this article aims to show how, in both church and school, a nature separate from humans is invented with which they should relate in a utilitarian and also contemplative way. Simultaneously nature’s opposite is invented–a culture that excludes animals and subjects them.

Rexistência Nas Fronteiras Do Capitalismo/Colonialismo: A Ecologia Política Do Isolamento E Da Soberania, Felipe Milanez

Tipití: Journal of the Society for the Anthropology of Lowland South America

Ofereço a perspectiva da ecologia política para rever e atualizar a política de “isolamento” e “não-contato” com base nos conceitos de soberania e necropolítica, sugerindo uma nova proposta de prática política para situações de conflitos em territórios ocupados por povos indígenas que resistem à conquista pela guerra e distanciamento. Da perspectiva do estudo dos conflitos ambientais, a ecologia política questiona a noção de isolamento ao inseri-la como parte do sistema mundo capitalista/colonial. Diante do quadro crescente de fascistização social e violência do Estado, cuja pressão sobre os territórios tornou-se ainda mais intenso, é a morte e a vida destes coletivos …

Tubes And Androgyny: Comment On "Thinking Through Tubes", Françoise Barbira Freedman

Tipití: Journal of the Society for the Anthropology of Lowland South America

In this comment on Stephen Hugh-Jones’s "Thinking Through Tubes" Françoise Barbira Freedman offers a feminist meditation on the semiotics of androgyny in Northwest Amazonian shamanism, ritual life and mythology. By focusing on processes of detotalization and retotalization that move beings from an androgynous state to a single-sex identity and back again, Barbira Freedman reveals a dynamic "one sex, two genders model of androgyny" that could not be further from a concept of androgyny as blurred gender. These movements in and out of a one sex state are largely the preserve of men so that androgynous features of the cosmos are …
