A Roadmap For Urban Evolutionary Ecology, Sarah E. Diamond, Ryan A. Martin
A Roadmap For Urban Evolutionary Ecology, Sarah E. Diamond, Ryan A. Martin
Faculty Scholarship
Urban ecosystems are rapidly expanding throughout the world, but how urban growth affects the evolutionary ecology of species living in urban areas remains largely unknown. Urban ecology has advanced our understanding of how the development of cities and towns change environmental conditions and alter ecological processes and patterns. However, despite decades of research in urban ecology, the extent to which urbanization influences evolutionary and eco-evolutionary change has received little attention. The nascent field of urban evolutionary ecology seeks to understand how urbanization affects the evolution of populations, and how those evolutionary changes in turn influence the ecological dynamics of populations, …

English Language and Literature
Cultural ecology and Ecofeminism are two concepts that intersect with each other. Both concepts define and reinforce each other. It could be claimed that, Ecofeminism is one manifestation of cultural ecology since the former tackles issues about feminism’s relationship with nature including nature domination and the duality of nature which find their echoes in cultural ecology as well. The whole idea of the earth’s subjugation and male domination as well as the male/ female duality of nature in general find resonance in feminist resistance to patriarchal domination which develop under the umbrella of Ecofeminism to be part of the struggle …

Evaluating The Need For Ocean Literacy In South Africa, Eugene Nyman
World Maritime University Dissertations
Pressures on the ocean are increasing due to anthropogenic activities, which has a caused decline in the health of the ocean. This has adversely affected the services and goods that populations are able to derive from the ocean. Various international agreements and partnerships, have been adopted to stem the human pressures on the ocean. However, the decline in the health of the ocean, has persisted. Ocean literacy is summarised by UNESCO (2017) as an individual being able to understand the influence they have on the ocean, and the ocean’s influence on their life. The concept has been developed with the …

New concepts have emerged in theoretical ecology with the intent to quantify complexities in ecological change that are unaccounted for in state-and-transition models and to provide applied ecologists with statistical early warning metrics able to predict and prevent state transitions. With its rich history of furthering ecological theory and its robust and broad-scale monitoring frameworks, the rangeland discipline is poised to empirically assess these newly proposed ideas while also serving as early adopters of novel statistical metrics that provide advanced warning of a pending shift to an alternative ecological regime. We review multivariate early warning and regime shift detection metrics, …

Watershed Sciences Faculty Publications
Fifty years ago, riparian habitats were not recognized for their extensive and critical contributions to wildlife and the ecosystem function of watersheds. This changed as riparian values were identified and documented, and the science of riparian ecology developed steadily. Papers in this volume range from the more mesic northwestern United States to the arid Southwest and Mexico. More than two dozen authors—most with decades of experience—review the origins of riparian science in the western United States, document what is currently known about riparian ecosystems, and project future needs. Topics are widespread and include: interactions with fire, climate change, and declining …

Mapping Maternal Mortality Rate Via Spatial Zero-Inflated Models For Count Data: A Case Study Of Facility-Based Maternal Deaths From Mozambique, Osvaldo Loquiha, Niel Hens, Leonardo Chavane, Marleen Temmerman, Nafissa Osman, Christel Faes, Marc Aerts
Obstetrics and Gynaecology, East Africa
Maternal mortality remains very high in Mozambique, with estimates from 2015 showing a maternal mortality ratio of 489 deaths per 100,000 live births, even though the rates tend to decrease since 1990. Pregnancy related hemorrhage, gestational hypertension and diseases such as malaria and HIV/AIDS are amongst the leading causes of maternal death in Mozambique, and a significant number of these deaths occur within health facilities. Often, the analysis of data on maternal mortality involves the use of counts of maternal deaths as outcome variable. Previously we showed that a class of hierarchical zero-inflated models were very successful in dealing with …

Civil and Environmental Engineering Faculty Research and Publications
Anaerobic membrane bioreactors (AnMBR) play a key role in future plans for sustainable wastewater treatment and resource recovery because they have no energy-intensive oxygen transfer requirements and can produce biomethane for renewable energy. Recent research results show that they can meet relatively stringent discharge limits with respect to BOD5 and TSS when treating municipal wastewater primary effluent. Sustainable used water recovery plans should also consider removal of unregulated pollutants. Antibiotic resistance genes (ARGs) represent an important emerging contaminant due to public health concerns surrounding the spread of infections resistant to common antibiotics. Conventional activated sludge processes have demonstrated mixed …

Balamuthia mandrillaris is a pathogenic free-living amoeba that causes a rare but almost always fatal infection of the central nervous system called granulomatous amoebic encephalitis (GAE). Two distinct forms of B. mandrillaris—a proliferative trophozoite form and a nonproliferative cyst form, which is highly resistant to harsh physical and chemical conditions—have been isolated from environmental samples worldwide and are both observed in infected tissue. Patients suffering from GAE are typically treated with aggressive and prolonged multidrug regimens that often include the antimicrobial agents miltefosine and pentamidine isethionate. However, survival rates remain low, and studies evaluating the susceptibility of B. mandrillaris to …

California Island Rediscovery: Building An Archive To Improve Conservation Today And Equip The Historical Ecologist Of Tomorrow, Scott A. Morrison, T. Scott Sillett, W. Chris Funk, Cameron K. Ghalambor, Torben C. Rick
Western North American Naturalist
An understanding of how past conditions have shaped present-day ecological patterns and trends is critical to science-based conservation management. Unfortunately, the records, specimens, and objects historical ecologists need to help generate that understanding are often lacking. And because of a general underinvestment by society in systematic collection and museum curation, future historical ecologists may be similarly limited in their ability to investigate conditions regarding our present day. Given the importance of historical data and materials in contemporary conservation decision-making, we suggest it is incumbent upon resource managers and scientists to ask whether additional research efforts are needed to document past …
Diets And Stable Isotope Signatures Of Yellowtail Rockfish (Sebastes Flavidus) In Central California, Jennifer Chiu
Diets And Stable Isotope Signatures Of Yellowtail Rockfish (Sebastes Flavidus) In Central California, Jennifer Chiu
Master's Theses
Studies of fish diets can improve the understanding of trophic distributions and the predatory role of a species in an ecosystem. Identifying the spatial and temporal variability in the diets of fishes can provide useful information for stock assessments and management. Yellowtail Rockfish (Sebastes flavidus) are a commercially and recreationally important fishery species, and abundant along the central California coast, yet the most recent studies of diets occurred over 20 years ago in Oregon and Washington. To provide current information from California, I examined the food habits of Yellowtail Rockfish collected near Cordell Bank, the Farallon Islands, and Half Moon …

Historical marine ecology provides information on past ocean conditions and community structure that can inform current conservation and management. In an era of rapid global ocean changes, it is critical that managers and scientists ensure sufficient documentation of past and present conditions of resources they manage or study. Documenting, archiving, and preserving historic and contemporary data will provide their colleagues in the future with more information to make robust science-based management decisions. Using a workshop approach, we identified research and archiving priorities to enhance documentation of the past and present conditions of coastal and marine ecosystems of the northern Channel …

Department of Anaesthesia
Background: The supply of controlled drugs is limited in the Far East, despite the prevalence of health disorders that warrant their prescription. Reasons for this include strict regulatory frameworks, limited financial resources, lack of appropriate training amongst the medical profession and fear of addiction in both general practitioners and the wider population. Consequently, the weak opioid tramadol has become the analgesic most frequently used in the region to treat moderate to severe pain.
Methods: To obtain a clearer picture of the current role and clinical use of tramadol in Southeast Asia, pain specialists from 7 countries in the region were …

Historical ecological research provides valuable insights for contemporary conservation management. Gaps in historical records, however, can limit the utility of that research. Future conservationists may therefore find themselves disadvantaged by the current societal trend of underinvestment in systematic collection of museum specimens and natural history information. To reduce that risk, we asked what managers and scientists could do today to better document the past and present conditions of Santa Cruz Island, California, as a means to improve both contemporary and future conservation. We focused our inquiry on the island’s terrestrial fauna, which includes numerous taxa of conservation concern. Here we …
An Evaluation Of Sciaenid Growth In The Gulf Of Mexico, Shane Flinn
An Evaluation Of Sciaenid Growth In The Gulf Of Mexico, Shane Flinn
LSU Master's Theses
Growth models estimate life history parameters that are used in the management of fisheries stocks. The most commonly used growth model in fisheries is the von Bertalanffy growth model (VBGM), yet it has been shown to provide a poor fit for length-at-age data of some species and other models exist. I reviewed 196 peer-reviewed age and growth studies and 50 NOAA stock assessments to examine temporal trends in the use of growth models and model selection in fisheries. I found that the use of multi-model frameworks has increased since the year 2000 and information theoretic approaches are replacing goodness-of-fit and …

Lay Summary: Adaptive immune proteins in mothers’ milk are more variable than innate immune proteins across populations and subsistence strategies. These results suggest that the immune defenses in milk are shaped by a mother’s environment throughout her life.
Background and objectives: Mother’s milk contains immune proteins that play critical roles in protecting the infant from infection and priming the infant’s developing immune system during early life. The composition of these molecules in milk, particularly the acquired immune proteins, is thought to reflect a mother’s immunological exposures throughout her life. In this study, we examine the composition of innate …

Evidence that agrichemicals are associated with the incidence of birth defects is inconsistent. We examined whether nitrate and nitrosatable agrichemicals present in well water are associated with birth defect rates in Nebraska counties. Birth defect data from the Nebraska Department of Health and Human Services, 2005-2014, were merged with well data obtained from the Quality-Assessed Agrichemical Contaminant Database for Nebraska Ground Water (1977-2014). Nebraska counties with higher rates of birth defects had a greater prevalence of agrichemicals in well water. Of the 33 contaminants sampled from different well types, nitrate and atrazine were of interest. Birth defect rates were negatively …
Alzheimer’S Disease And Alpha-Synuclein Neuropathology In The Olfactory Bulbs Of Children And Young Adults ≤40years Exposed To High Levels Of Fine Particulate Matter Air Pollution In Metropolitan Mexico City: Apoe4 Carriers At Higher Risk Of Suicide Accelerate Their Olfactory Bulb Damage, Partha S. Mukherjee
Mathematics Faculty Publications and Presentations
There is growing evidence that air pollution is a risk factor for a number of neurodegenerative diseases, most notably Alzheimer’s (AD) and Parkinson’s (PD). It is generally assumed that the pathology of these diseases arises only later in life and commonly begins within olfactory eloquent pathways prior to the onset of the classical clinical symptoms. The present study demonstrates that chronic exposure to high levels of air pollution results in AD- and PD-related pathology within the olfactory bulbs of children and relatively young adults ranging in age from 11 months to 40 years. The olfactory bulbs (OBs) of 179 residents …
Male-Female Differences In The Prevalence Of Non-Hodgkin Lymphoma And Residential Proximity To Superfund Sites In Kentucky, Ramona Stone, W. Brent Webber
Male-Female Differences In The Prevalence Of Non-Hodgkin Lymphoma And Residential Proximity To Superfund Sites In Kentucky, Ramona Stone, W. Brent Webber
Public Health Sciences Faculty Publications
Non-Hodgkin lymphoma (NHL) is a category of cancers that arise from lymphocytes. Previous work by the authors demonstrated a significant association between residential proximity to Superfund sites in Kentucky and cumulative incidence rates of NHL. In both the U.S. and Kentucky, age-adjusted NHL rates in males consistently exceed rates in females, despite NHL often arising later in the lifespan when females outnumber males. The current investigation sought to determine whether the NHL rate difference by sex is associated with proximity to environmental toxicants. Cancer data for a period of 18 years were obtained from the Kentucky Cancer Registry. Superfund geospatial …

Decadal Effects Of Thinning On Understory Light Environments And Plant Community Structure In A Subtropical Forest, Ho-Chen Tsai, Jyh-Min Chiang, Ryan Mcewan, Teng-Chiu Lin
Biology Faculty Publications
Canopy-opening disturbance such as thinning has immediate and substantive effects on understory microclimate and therefore the establishment and growth of understory plants. A large number of studies have reported the effects of thinning on tree growth, but few studies have examined long-term effects of thinning on understory light environments and species and functional diversity of understory plants. Even less is known whether the change in understory plant community structure observed following canopy disturbance is short-lived and would diminish as the canopy closes or a long lasting due to legacy effects. We examined the effects of an experimental removal of 25% …

This study investigated the association between black carbon (BC) exposure and hospital admissions (HAs) and outpatient department/emergency room (OPD/ER) visits for cardiovascular diseases (CVD) among residents of Karachi, the largest city in Pakistan. We measured daily concentrations of BC in fine particulate matter (PM2.5) and collected records of HAs and OPD/ER visits for CVD from 2 major tertiary care hospitals serving Karachi for 6 weeks continuously during each quarter over 1 year (August 2008–August 2009). We subsequently analyzed daily counts of hospital and BC data over 0–3 lag days. Daily mean BC concentrations varied from 1 to 32 µg/m3 . …

Vector Competence Of Aedes Bromeliae And Aedes Vitattus Mosquito Populations From Kenya For Chikungunya Virus, Francis Mulwa, Joel Lutomiah, Edith Chepkorir, Samwel Okello, Fredrick Eyase, Caroline Tigoi, Michael Kahato, Rosemary Sang
All Peer-Reviewed Publications
Background: Kenya has experienced outbreaks of chikungunya in the past years with the most recent outbreak occurring in Mandera in the northern region in May 2016 and in Mombasa in the coastal region from November 2017 to February 2018. Despite the outbreaks in Kenya, studies on vector competence have only been conducted on Aedes aegypti. However, the role played by other mosquito species in transmission and maintenance of the virus in endemic areas remains unclear. This study sought to determine the possible role of rural Aedes bromeliae and Aedes vittatus in the transmission of chikungunya virus, focusing on Kilifi and …

Capture-recapture methods are commonly used to estimate abundance and density of wild animal populations. Although a variety of sophisticated analytical techniques are available to evaluate capture-recapture data, vertebrate monitoring programs often lack the resources (e.g., time, personnel, and/or analytical expertise) to apply these methods. As an alternative, simple population indices, such as counts of unique individuals, may provide sufficient information to detect meaningful changes in population size. In this study we investigated whether a population index, easily generated from mark-recapture data under all conditions, might be used to provide valid ecological information for managers interested in long-term population trends of …
Habitat Preferences Of Blue Marlin (Makaira Nigricans) And Black Marlin (Istiompax Indica) In The Eastern Pacific Ocean, Nima Farchadi, Michael G. Hinton, Andrew R. Thompson, Zhi-Yong Yin
Habitat Preferences Of Blue Marlin (Makaira Nigricans) And Black Marlin (Istiompax Indica) In The Eastern Pacific Ocean, Nima Farchadi, Michael G. Hinton, Andrew R. Thompson, Zhi-Yong Yin
Theses
Overexploitation and climate change can reduce the abundance and shift the spatial distribution of marine species. Determining the habitat suitability of a mobile pelagic species, such as Makaira nigricans (BUM) and Istiompax indica (BLM), can help describe their spatiotemporal distribution patterns over a broad spatial scale, which is a crucial need for fisheries management. Using 14 years (1997-2010) of Inter-American Tropical Tuna Commission (IATTC) catch data from purse-seine vessels in the eastern Pacific Ocean (EPO), we modeled the dynamic habitat suitability of BUM and BLM in response to environmental variables within the EPO using a species distribution model (MaxEnt) with …

An integrated understanding of both social and ecological aspects of environmental issues is essential to address pressing sustainability challenges. An integrated social-ecological systems perspective is purported to provide a better understanding of the complex relationships between humans and nature. Despite a threefold increase in the amount of social-ecological research published between 2010 and 2015, it is unclear whether these approaches have been truly integrative. We conducted a systematic literature review to investigate the conceptual, methodological, disciplinary, and functional aspects of social-ecological integration. In general, we found that overall integration is still lacking in social-ecological research. Some social variables deemed important …

Coastal estuaries represent areas of high biological invasions by virtue of their economic importance as ports. We report on the first occurrence of the non-native hydrozoan Moerisia sp. in coastal New Jersey, USA. Through the use of artificial settling plates, several diminutive, unknown cnidarian polyps were isolated. Initial morphological assessment indicated that two of the unknown polyps were keyed to Moerisia. We then used universal cnidarian primers to amplify and sequence the 16S rDNA mitochondrial locus for molecular identification. Upon evaluation and editing of sequences, two of the unknown polyps were identified as belonging to a group of unresolved Moerisia …

Lianas are a quintessential feature of tropical forests and are often perceived as being poorly studied. However, liana removal studies may be one of the most common experimental manipulations in tropical forest ecology. In this review, we synthesize data from 64 tropical liana removal experiments conducted over the past 90 yr. We explore the direction and magnitude of the effects of lianas on tree establishment, growth, survival, reproduction, biomass accretion, and plant and animal diversity in ecological and forestry studies. We discuss the geographical biases of liana removal studies and compare the various methods used to manipulate lianas. Overall, we …
