Rickettsia philipii (type strain “Rickettsia 364D”), the etiologic agent of Pacific Coast tick fever (PCTF), is transmitted to people by the Pacific Coast tick, Dermacentor occidentalis. Following the first confirmed human case of PCTF in 2008, 13 additional human cases have been reported in California, more than half of which were pediatric cases. The most common features of PCTF are the presence of at least one necrotic lesion known as an eschar (100%), fever (85%), and headache (79%); four case-patients required hospitalization and four had multiple eschars. Findings presented here implicate the nymphal or larval stages of D …

Intensive, Regular Sampling And Removal Of Modest Numbers Of Fishes Shows No Measurable Impact On Fish Populations In Three Streams Of North Georgia, Steven L. Powers

Southeastern Fishes Council Proceedings

Recent publications and restrictions on collecting by state fish and game managers indicate a growing concern regarding the impact of field sampling on native fish populations. To evaluate the validity of these concerns, data from five life-history studies conducted in Cherokee County, Georgia were examined to test the hypothesis that regular sampling has a negative impact on fish populations. Number of individuals collected was divided by time collecting to calculate catch per unit effort (CPUE) as an indicator of relative abundance for each species. The collecting sequence (i.e. the number of times a species had previously been sampled) was regressed …

Variability Of Lacustrine Sediment Proxy Responses To Late Holocene Climate Change As Modified By Lake Specific Processes: A Review Of Ecological And Geophysical Processes Across Northern And Eastern Iceland, Mallory Mintz

Independent Study Project (ISP) Collection

Consistenly-deposited lake sediments provide some of the highest resolution records of local and global climates in the past, offering the potential to better understand modern climate change in the context of past climate variability. In relating proxies to their respective climate regimes, the environmental cues that the specific proxies reacted to must be isolated from the general noise of possible local influences. In this investigation, biogenic silica (BSi), total organic carbon (TOC), δ13C values, and carbon: nitrogen ratios were analyzed between lakes through northern Iceland, to review possible complicating factors specific to the use of lacustrine proxies in the interpretation …

Prehistoric Pathoecology As Represented By Parasites Of A Mummy From The Peruaçu Valley, Brazil, Karl Reinhard, Adauto Araújo

Karl Reinhard Publications

Paleopathologists have begun exploring the pathoecology of parasitic diseases in relation to diet and environment. We are summarizing the parasitological findings from a mummy in the site of Lapa do Boquete, a Brazilian cave in the state of Minas Gerais. These findings in context of the archaeology of the site provided insights into the pathoecology of disease transmission in cave and rockshelter environments. We are presenting a description of the site followed by the evidence of hookworm, intestinal fluke, and Trypanosoma infection with resulting Chagas disease in the mummy discovered in the cave. These findings are used to reconstruct the …

Neighborhood Characteristics Contribute To Urban Alcohol Availability: Accounting For Race/Ethnicity And Social Disorganization, Aleksandra J. Snowden

Social and Cultural Sciences Faculty Research and Publications

This study examined the role that race/ethnicity and social disorganization play in alcohol availability in Milwaukee, Wisconsin, census block groups. This study estimated negative binomial regression models to examine separately the relationship between neighborhood racial/ethnic composition and social disorganization levels for (1) total, (2) on-premise, and (3) off-premise alcohol outlets. Results of this study suggest that proportion Hispanic was positively associated with total and with off-premise alcohol outlets. Second, proportion African American was negatively associated with on-premise alcohol outlets and positively associated with off-premise alcohol outlets. Proportion Asian was not associated with total, on-premise, or off-premise alcohol outlets. However, the …

Viral Zoonoses That Fly With Bats: A Review, Alfonso Calderon, Camilo Guzman, Jorge Salazar-Bravo, Luiz Tadeu Figueiredo, Salim Mattar, German Arrieta

MANTER: Journal of Parasite Biodiversity

Emerging infectious diseases are a growing threat to human health and a great challenge for global medical attention systems. Governmental agencies in tropical regions with abundant zoonotic pathogens should implement an active vigilance/monitoring model in bat reservoir populations because of their species richness, abundance and dispersal capabilities. Chiropterans represent approximately 20% of all mammal species, the second largest order in terms of number of species after rodents. Importantly, bats constitute natural reservoirs for potential infection of humans of several infectious disease agents such as Coronavirus, Filovirus, Lyssavirus, Paramyxovirus, and Flavivirus. Local disease outbreaks caused by new pathogens can …

Aspects Of Host Usage Of The Chestnut Lamprey (Ichthyomyzon Castaneus) In Arkansas, Jeremiah Max Salinger

Student Theses and Dissertations

Most native North American lamprey species are imperiled in some manner, but are curiously understudied. The research described in this thesis addresses the adult feeding biology of the Chestnut Lamprey (Ichthyomyzon castaneus), a freshwater parasitic lamprey native to the southeastern United States. This thesis addresses Chestnut Lamprey attachment site selection and size-selective parasitism of Rainbow Trout (Oncorhynchus mykiss) in an outdoor laboratory setting, as well as Chestnut Lamprey host usage and distribution in Arkansas. Approximately 75% of the 80 wounded Rainbow Trout studied were attacked in their dorsal mid-section. Chestnut Lampreys were found to select shorter hosts, with no mass …

Torres-Castro, Carlos Machaín-Williams, Nohemi Cigarroa-Toledo, Lorenzo Sodá, Gabriela López-Manzanero, Josué R. Meza-Sulú, Victor M. Vidal-Martínez

MANTER: Journal of Parasite Biodiversity

Anthropocommensal rodents live in close proximity to humans in many habitats around the world. They are a threat to public health because of the pathogens they carry. Recent studies in Mérida, Yucatán, México, have shown that commensal rodents harbor potential zoonotic pathogens such as bacteria, helminths, and viruses. In this study, we describe reproductive and demographic parameters of house mice and black rats present in households from Mérida, Yucatán, México, a municipality located in a tropical region in southern México. Rodents were trapped in 142 households within the municipality of Mérida from 2011 to 2014. A total of 832 rodents …

Eco-Engineered Rock Pools: A Concrete Solution To Biodiversity Loss And Urban Sprawl In The Marine Environment, Lb Firth, Ka Browne, Am Knights, Sj Hawkins, R Nash

School of Geography, Earth and Environmental Sciences

In coastal habitats artificial structures typically support lower biodiversity and can support greater numbers of non-native and opportunistic species than natural rocky reefs. Eco-engineering experiments are typically trialed to succeed; but arguably as much is learnt from failure than from success. Our goal was to trial a generic, cost effective, eco-engineering technique that could be incorporated into rock armouring anywhere in the world. Artificial rock pools were created from manipulated concrete between boulders on the exposed and sheltered sides of a causeway. Experimental treatments were installed in locations where they were expected to fail and compared to controls installed in …

Integrating Social Determinants Of Health With Treatment And Prevention: A New Tool To Assess Local Area Deprivation, Andrew R. Maroko, Thao M. Doan, Peter S. Arno, Megan Hubel, Shirley Yi, Deborah Viola

Publications and Research

We assessed the appropriate geographic scale to apply an area deprivation index (ADI), which reflects a geographic area’s level of socioeconomic deprivation and is associated with health outcomes, to identify and screen patients for social determinants of health. We estimated the relative strength of the association between the ADI at various geographic levels and a range of hospitalization rates by using age-adjusted odds ratios in an 8-county region of New York State. The 10-km local ADI estimates had the strongest associations with all hospitalization rates (higher odds ratios) followed by estimates at 20 km, 30 km, and the regional scale. …

Current Knowledge Of Studies Of Pathogens In Colombian Mammals, Viviana Gonzalez-Astudillo, Héctor E. Ramírez-Chaves, Joerg Henning, Thomas R. Gillespie

MANTER: Journal of Parasite Biodiversity

Mammals provide an important ecological habitat or niche space to microbial diversity, protistans (or protozoans) and metazoan parasites that can have profound effects on both human and animal health. Thus, understanding the status of mammalian species as hosts for pathogens holds relevance, especially during this time of anthropogenic environmental change. Despite the great diversity in the mammal fauna of Colombia, data in the literature on the occurrence of parasites and pathogens in these mammals are scarce and widely scattered. In order to understand the state of the knowledge of pathogens carried by wild mammals in Colombia, a systematic review of …

Internal Medicine, East Africa

The burden of HIV/AIDS and other transmissible diseases is higher in prison and jail settings than in the non-incarcerated communities that surround them. In this comprehensive review, we discuss available literature on the topic of clinical management of people infected with HIV, hepatitis B and C viruses, and tuberculosis in incarcerated settings in addition to co-occurrence of one or more of these infections. Methods such as screening practices and provision of treatment during detainment periods are reviewed to identify the effect of community-based treatment when returning inmates into the general population. Where data are available, we describe differences in the …

The Economic Value Of Forest Park Ecosystem Services: Results Of Five Focus Groups Conducted In Spring 2016, Randall A. Bluffstone, Pablo Barreyro, Jenny Dempsey Stein, Cody Kent, Antonia Machado

Economics Faculty Publications and Presentations

Objective: This initial phase of research lays the foundation for a survey using contingent valuation (CV) and choice experiment (CE) methods. We asked select Portland residents what they care about most in Forest Park, their willingness to pay (WTP) for improving ecosystem services and how they generally think about the value of those goods and services. These results will help us narrow the experimental design of the forthcoming CV/CE study.

Approach: We conducted a focus group in each of Portland’s 5 “quadrants.” We chose each location - Skyline, St. John’s, Cully, Foster-Powell and Hillsdale - based on either its proximity …

Increasing The Depth Of Current Understanding: Sensitivity Testing Of Deep-Sea Larval Dispersal Models For Ecologists, Rebecca E. Ross, W. Alex M. Nimmo-Smith, Kerry L. Howell

School of Biological and Marine Sciences

Larval dispersal is an important ecological process of great interest to conservation and the establishment of marine protected areas. Increasing numbers of studies are turning to biophysical models to simulate dispersal patterns, including in the deep-sea, but for many ecologists unassisted by a physical oceanographer, a model can present as a black box. Sensitivity testing offers a means to test the models' abilities and limitations and is a starting point for all modelling efforts. The aim of this study is to illustrate a sensitivity testing process for the unassisted ecologist, through a deep-sea case study example, and demonstrate how sensitivity …

A Quantitative Analysis Of Hugelkultur And Its Potential Application On Karst Rocky Desertified Areas In China, Megan Laffoon

Mahurin Honors College Capstone Experience/Thesis Projects

A type of environmental degradation, karst rocky desertification (KRD) refers to areas where the soil loss exposes the bedrock and reduces the land’s ability to sustain life and is particularly widespread through the vast karst area of rural southwest China. Hugelkultur is a permaculture method that harnesses the wood decomposition process by burying logs beneath soil. We proposed that hugel beds will demonstrate a higher water holding capacity and enhance soil development, in a way that may show promise as a potential method to help alleviate problems of KRD. Soil samples were taken from hugel plots, non-hugel plots, and KRD-like …

Alaskan Arctic Epibenthic Communities: Distribution Patterns, Links To The Environment, And Brittle Star Population Dynamics, Alexandra Mariela Ravelo

Marine Biology

The Arctic marine shelves are characterized by areas of high and low invertebrate standing stock and communities that vary spatially in patches. Large-scale environmental characteristics, such as the distribution of water masses, the fenology of sea ice cover, and variability of water depth define changes in epibenthic community structure throughout the Arctic shelves. The longevity and relatively low mobility of epibenthic invertebrates make them especially relevant as indicators of long-term environmental patterns. In terms of standing stock and biomass, the most representative group among Arctic epibenthic taxa are brittle stars. Large areas of the Arctic shelves have dense assemblages of …

Using Ecological Production Functions To Link Ecological Processes To Ecosystem Services, Randall Jf Bruins, Timothy J. Canfield, Clifford Duke, Larry Kapustka, Amanda M. Nahlik, Ralf B. Schäfer

United States Environmental Protection Agency: Publications

Ecological production functions (EPFs) link ecosystems, stressors, and management actions to ecosystem services (ES) production. Although EPFs are acknowledged as being essential to improve environmental management, their use in ecological risk assessment has received relatively little attention. Ecological production functions may be defined as usable expressions (i.e., models) of the processes by which ecosystems produce ES, often including external influences on those processes. We identify key attributes of EPFs and discuss both actual and idealized examples of their use to inform decision making. Whenever possible, EPFs should estimate final, rather than intermediate, ES. Although various types of EPFs have been …

Landscapes Of Environmental Justice: A Post-Structural Analysis Of Ecological Structures And Environmental Discourses, Sima Namin

Planning Dissertations - Archive

Although application of ecological concepts and looking at the city as an 'ecological space' or ecosystem is not new in planning (e.g. Chicago school), in the context of environmental justice research there is a need for a more integrated approach towards the complex interrelations between human aspects of urban landscapes and urban ecology. Consequently, the first starting point of my research is that studying environmental justice also requires an understanding of environmental health. The second defining point of this research is influenced by the notion of questioning science and research as a 'social construct.' Drawing on Foucault's legacy of discourse …
